Attitude set device of onvehicle equipment

[Detailed Description of the Invention]

The object Co of [invention Field 1 of [invention The present invention relates to the attitude setting device of the equipment on a vehicle which carries out the positioning drive of the postures, such as a sheet on a vehicle, and a steering operation part, with an electric motor, It is related with the attitude setting device of equipment on a vehicle which is provided with a plurality of drive system and a plurality of posture adjustment mechanisms, and is especially positioned automatically in the position which defined beforehand the posture of a plurality of equipment on a vehicle with predetermined directions.

[Description of the Prior Art] A driver sheet position, a steering wheel position, etc. can adjust now freely, and it is usual so that Triba which operates it can generally relieve all the operation in a vehicle at the time of operation. The driver sheet, the steering wheel, etc. are set as the posture at the time of operation. However, in the state of this as, a steering wheel and a seat back become hindrance, and since a sheet etc. are positioned so that only space required for a driver to move a hand and a leg may remain at the time of operation, when a driver gets on and off on a vehicle, a driver cannot be got on and off, unless it takes an unnatural posture. Then, the dill 841m style and telescope mechanism of a steering operation part are made electric, and a steering operation part is positioned to a retreating position at the time of getting on and off, Vehicle top Posture control @ (Japanese Patent Application No. No. 130884 [ 56 to ]) positioned to the predetermined running position at the time of operation The rotation control device (JP,58-214423,A) of the vehicle upper sheet which forms the device which rotates a sheet by an electric mechanism, and turned the sheet to the direction of a doorway at the time of getting on and off is proposed.

In problem J which [invention tends to solve, and time, an electric attitude setting device is in a vehicle as double A few teeth respectively at a steering operation part, a sheet, a mirror, etc. Therefore, when performing return operation to the posture before an evacuation posture setup at the time of the above driver getting on and off, and evacuation, or when performing posture adjustment united with the physique of the driver, it is preferred to carry out posture adjustment of a plurality of equipment on a vehicle. In this kind of device, since the speed of the source of a drive (electric motor) is slow, posture adjustment takes comparatively long time. Therefore, when carrying out posture adjustment of a plurality of equipment on a vehicle, the direction which drove a plurality of equipment on a vehicle simultaneously can complete a posture setup in a short time. However, since very big current will flow if a plurality of electric motors are driven simultaneously, the voltage drop by wiring etc. is large, and it is posture+111 by the influence! The drive of the fi1 device itself may stop or malfunction may arise to other devices. For this reason, if one posture setup is completed and that electric motor is conventionally suspended even when a plurality of equipment on a vehicle needs to be posture adjusted, he is trying to start the drive of other equipment on a vehicle. For this reason, a posture setup has taken very long time. An object of the present invention is to shorten the time which a posture setup when a plurality of equipment on a vehicle needs to be posture adjusted takes, and to prevent generating of malfunction of the various device under posture adjustment.

[Elements of the Invention] [Means for Solving the Problem] In order to achieve the above-mentioned object, if the necessity for posture adjustment of a plurality of equipment on a vehicle arises, after starting a drive of equipment on [ of one ] a vehicle first and fully stabilizing transitional current at the time of an energization start of the source of a drive, a drive of equipment on [ another ] a vehicle is started in the present invention.

[Function] Generally, very big transitional current (incoming current) flows into an electric motor immediately after energization. For this reason, when the energization start of a plurality of electric motors is carried out simultaneously, total of the current which flows through a battery becomes still larger, and its voltage drop of wiring and the battery itself is remarkable at the time of this energization start. However, it is only immediately after an energization start that incoming current flows, and it is the inside of a short time after that. A current value returns to a regular value. In a stationary state, even if it drives many electric motors simultaneously, total of the current which flows through a battery is in tolerance level. Therefore, as long as only the amount of [ of current ] transitional period shifts the timing of an energization start mutually, a plurality of drive systems may be driven simultaneously. If the value of the current which actually flows through a battery etc. is measured and it judges whether it is a transitional period of Wl style, it is not necessary to define beforehand the time lag at the time of an energization start. By the way, when adjusting automatically the inclination posture of a steering wheel, and the direction position of a rotation axis at the time of getting on and off, a feeling of freedom to which the direction given to a driver gives touch that a steering wheel separates from a driver quickly at the time of away (Withdraw'a) operation to a driver is strong. At the time of return operation, the feeling of oppression which the one where the approach operation start to the driver of a steering wheel is slower gives to a driver becomes small. However, if the completion of positioning to the running position of a steering wheel is slow in return operation, it will be overdue that operation becomes possible. Then, in the desirable example of the present invention, at the time of away operation, the posture adjustment start of the telescope mechanism is carried out previously, and posture adjustment of a tilt mechanism is started continuously. At the time of return operation, the posture adjustment start of the tilt mechanism is carried out previously, and posture adjustment of a telescope mechanism is started continuously. Since touch that a steering wheel separates from a driver is stronger than carrying out posture adjustment of the tilt mechanism in evacuation, i.e., the rise direction, when posture adjustment of the telescope mechanism is carried out in evacuation, i.e., the shortening direction, a feeling of freedom of a driver becomes strong by performing posture adjustment of a tilt mechanism previously. By making posture adjustment of a telescope mechanism into behind at the time of a return, the feeling of oppression of a driver becomes small.

While nut section 221 is formed, the nut section 221 and screw 222 to screw are supported at the right end of retaining bracket 217 at the left end lower part of hinged cantilever 219, enabling free rotation. Bearing bracket 223 adheres to retaining bracket 217. And while bearing bracket 223 covers screw 222, the move space of screw 222 is secured (the refer toj [ 5 ] figure). Gear 243 was allocated in screw 222 and one by the left end portion of screw 222, and it has geared with Worm gear 226 attached to shaft 225 of direct-current motor 224 (M3 of Drawing 6) into it. Direct-current motor 224 is attached to retaining bracket 217. Therefore, if motor 224 rotates, screw 222 will rotate. Thereby, nut section 221 moves along the direction of an axis in screw 222 top. Hinged cantilever 219 which has nut section 221 moves to retaining bracket 217. Therefore, inner shaft 215 takes out and inserts to outer shaft 214.

A standby signal is generated after t4 progress for a predetermined period [ timer 2 ] for making CPU standby. if a power supply turns on microcomputer CPU -- the -- although processing is performed from the start (power supply ON) of the main routine shown ina [ 7 ] figure, two processings are performed aside from the processing. One of them is external interruption processing (the refer toQ [ 7 ] figure) according to external interruption from vehicle speed sensor SSW, and another is timer interruption processing (it is referring to the figure to the 7th) performed whenever an internal timer calculates a predetermined value. In this example, a timer interrupt occurs every 5-m5ec. External interruption is explained first. In this interruption, if it roughly says, processing which measures the vehicle speed will be performed. Whenever the value of a vehicle speed timer processes this external interruption, it is cleared by 0. The value of a vehicle speed timer is counted up by processing of timer interruption performed every 5-m5cc. Therefore, when an external interrupt occurs, the time from the last end time of interruption to the present always comes. Since it is falling of a vehicle speed signal which an external interrupt generates in this example, the value of a vehicle speed timer is equivalent to the time of one cycle of a vehicle speed signal. In fact, in order to avoid the influence of the variation in the duty of a sensor, four samplings were performed and the average value is detected. Therefore, four vehicle speed registers SPO, SPI, SP2, and SP3 are used. Whenever it processes external interruption, the contents of each register SP3 *SP2 and SPI are transmitted to register SP2.SPI and SPO, respectively, and the newest vehicle speed goes into register SP3. And the four contents of register 5PO-5P3 are added, and let the result be the measurement vehicle speed. since [ however, ] this value is a cycle of a vehicle speed pulse -- the usual vehicle speed -- small diameter with a conversely large value -- it corresponds to the Sana vehicle speed. Next, timer interruption is explained. If the internal timer of a microcomputer calculates 5-m5ec, it will jump into the portion of the beginning of timer interruption shown [ 7th ] in a figure. And the contents of the various registers are evacuated, next timer interruption is set up, the state of various input boats is read, and a 60-m5ec counter is carried out +1 (increment). If the value of the 60-m5ec counter has not reached 5Qmsec, the contents of the register are returned and it returns to a main routine immediately, but if the value of a counter is 60-m5ec, the next processing will further be performed. First, the value of a 60-m5ec counter is cleared and a vehicle speed timer, a tilt timer, a Telescopic timer, and a sheet timer are carried out +1. Next, A/D conversion machine ADC is controlled and they are a tilt posture and a telescope posture. The state of a sheet posture, battery voltage, and a manual posture configuration switch (SWI~5W4) is read. Next, it asks for the average speed of posture change from the obtained attitude information. Processing of a tilt posture is explained. In this example, in order to equip four tilt posture registers TIPm (m=o~3) in order to hold the tilt attitude information for 4 times, and to hold the tilt speed information for 5 times, five tilt speed register Tl5Pn (n=o~4) is equipped. The newest tilt posture is contained in register TIPO, the last tilt posture goes into TIPI and the tilt posture of @ Every time is contained in TiF4, respectively. In this example, a difference (absolute value) with the value of the posture before last and the newest posture is put into tilt speed register Tl5PO. Other tilt speed register Tl5PI. Tl5P2. The last tilt speed, the tilt speed before last, and ... are contained in ..., respectively. Then, five tilt speed information is added and it stores in register TI SP by making the result into a tilt speed authorization result. By next, the contents of each tilt posture register rIP (m) are transmitted to T I P (m+1), and the contents of each tilt speed register Tl5P (n) are transmitted to T I S P (n+1.). Processing of a telescope posture and a See 1~posture is the same as that of the case of a tilt posture. T E P (m) is a Telesf posture register, TESP (n) is a Telescopic speed register, and it is S E P. (m) is a posture register for See 1, and 5EP (n) is a sheet speed register. If a tilt refreshment flag and a tele Scolli fresh flag are 1, the contents of tilt posture register TIPO and Telescopic posture register TEPO are memorized in a memory as each new memory posture, respectively. Next, the condition precedent of the inversion operation based on the surveillance of the existence of an electrical overload and electrical overload detection is judged about each of a tilt mechanism, a telescope mechanism, and sheet drive mechanism. First, a tilt mechanism is explained. It progresses to the next without doing anything, when tilt motor M2 is OFF. Since tilt inversion flag F6a is usually O when tilt motor M2 is ON, it progresses to electrical overload detection. However, in order to avoid detection of the incoming current at the time of motor-on as the value of a tilt timer is 11 or less for a predetermined period, the mask of the electrical overload detection is carried out. Three conditions are judged if a tilt timer is 11 or more. One is detection of the high current detected by each over-current detection circuit CDI~CD3. This arises, when a motor locks. Another is overflow of a tilt timer. Usually, although a posture setup is ended in 2 or about 3 seconds, when abnormalities arise, the motor may have driven continuously for a long time. So, in this example, if tilt driving time reaches at 5 seconds, it will have judged unusually. Another condition is the variation speed of a tilt posture. The information on the variation speed of a tilt posture is stored in register Tl5P as mentioned above. In the usual operation, if posture variation speed is slower than a predetermined value as compared with the predetermined value which defined the value of register Tl5P in the program beforehand since attitude information changes by predetermined inclination during the drive of a motor, it can judge with it being an electrical overload. If at least one of these three conditions is unusual. Tilt stop flag F31 is set to "1." If tilt stop flag F31 is set to "1", by a main routine, tilt inversion flag F6a will be set to "1", so that it may mention below. If a tilt inversion flag is set to "1", it will progress to the judgment of the condition precedent of inversion operation. There are three conditions of this judgment in this example. The priority of a stroke is the highest. That is, inversion mode will be canceled, if a posture when an electrical overload is detected is compared with the present posture and the stroke reaches a predetermined value. Usually, a motor stops by this judgment. Another condition is a case where it becomes the predetermined posture defined beforehand. The one [ remaining ] is a case where time in inversion mode reaches a predetermined value (t3) (that is, when Time Oba is carried out). If any these one condition is fulfilled, a tilt inversion flag will be cleared to "0" and a tilt inversion timer will be cleared. Next, it progresses to processing (refer to the 7thohm figure) of a telescope mechanism. It progresses to the next without doing anything, as well as the case of a tilt mechanism when telescope motor M3 is OFF. By ON, motor M3 progresses that Telescopic inversion flag F6b is rOJ to electrical overload detection. Also in this case, three conditions, detection of an over-current, overflow of a Telescopic timer, and the variation speed of a Telescopic posture, are judged, and "1" is set to Telescopic stop flag F32 as at least one is abnormalities (electrical overload). If a Telescopic stop flag is set to "1", by a main routine, Telescopic inversion flag F6b will be set to "1", so that it may mention below. If a Telescopic inversion flag is set to 1, an inversion condition precedent will be judged. If the conditions of any one of are fulfilled when it changes into the predetermined state which the number of these conditions was also three, and the telescope posture defined beforehand when the stroke under inversion became more than predetermined, and when inversion time amounts to t3 for a predetermined period, A Telescopic inversion flag is cleared to 0 and a Telescopic inversion timer is cleared. Next, it progresses to processing (refer to the 7th m figure) of sheet drive mechanism. It progresses to the next without doing anything, as well as the case of a tilt mechanism when sheet motor M1 is OFF. By ON, motor M1 progresses that sheet inversion flag F6c is "0" to electrical overload detection. Also in this case, three conditions, detection of an over-current, overflow of a sheet timer, and the variation speed of a sheet posture, are judged, and it is .. At least one sets "l" to sheet stop flag F33 as it is unusual Overload. If a sheet stop flag is set to "1", by a main routine, sheet inversion flag FCC will be set to "1", so that it may mention below. If a sheet inversion flag is set to "1", an inversion condition precedent will be judged. The number of these conditions is also three, and if the conditions of any one of are fulfilled when it changes into the predetermined state which the sheet posture defined beforehand when the stroke under inversion became more than predetermined, and when inversion time amounts to t3 for a predetermined period, a sheet inversion flag will be cleared to 0 and a sheet inversion timer will be cleared. Next, when the output of over-current detection circuit CD4 is seen, it confirms whether the over-current is flowing into relay RL1~RL6 and the over-current is flowing, a relay is set as OFF. Then, the main routine which begins from a "start" of the 7th the a figure is explained. ON of a power supply will perform initial setting first. That is, an output port is set as an initial state (motor-off), and the contents of the memory used as a counter, a register, a flag, etc. are cleared. Here, the limit position setting method flag F1 is altogether cleared by "0." Next, the output of regulators R and E G is checked. If the engine is operating in regulator REG, predetermined voltage (voltage of a battery) has appeared in it, but voltage will become zero if the engine has stopped. Therefore, the existence of engine operation is judged by supervising the output of regulator REG. During engine operation, it is a manual figure! The manual posture adjustment according to operation of 3 configuration-switch SWI~SW4 is permitted. Also when ignition switch IGS is ON, manual posture adjustment is permitted. If one state of manual switch SW1~SW4 has change, the contents of a tilt timer and the Telescopic timer will be cleared. First, the manual posture adjustment processing when not having set up immediately after power supply ON (i.e., a limit position) is explained. If there are manual tilt rise directions (SWI turns on), the limit position setting method flag FLU will be checked at Step 7. At first, since flag FLU is "0", 1 usual continues and it is Step 9-10-11-23-2-4-6-7.... Processing is repeated and performed. If the lapsed time from the time at which tilt timer T1 was cleared exceeds 0.06 second when switch SWI is turned ON namely, it will progress to the next of Step 9 at Step 14, and will set a tilt motor as a drive OFF state. And if the lapsed time will be 0.26 second, again, it will progress to the next of Step 9 at Step 10, and will carry out the drive set of the tilt motor in the rise direction. That is, in manual operation, if it continues pushing a switch, and - Responsibility and posture adjustment will be stopped and 0.2 second (TB) will pass after that after performing (TA) and posture adjustment for 0 or 06 seconds at first, posture adjustment will be started again (refer to the 8th figure). If a switch is turned OFF, posture adjustment will stop immediately. By performing such processing, fine tuning of the posture in manual operation becomes easy. namely, -- if the time required (TC, TD) is 0.06 second and a range for 0.26 second when operation which changes a manual switch into an ON state from an OFF state, and it returns to an OFF state again (it stops pushing after pushing a switch) is performed Since the time which a tilt motor drives to the one operation is regularity (0 or 06 seconds) no matter what operation it may perform, even if it performs switch operation slowly, a posture does not change greatly across a target position by one switch operation. Therefore, a posture can be brought little by little close to a target position by performing several switch operations, and if it further continues pushing 6 manual tilt rise switch SWI which can perform exact positioning easily, the marginal position where a tilt mechanism is mechanical will be arrived at. In that case, an electrical overload is detected and tilt stop flag F31 is set to "1" by the above-mentioned timer interruption processing (Drawing 7) in Step 319. Since hula;F31 is "1" when processing of a main routine progresses to Step 10 after that, it progresses to Step 20 next. In Step 20, it is based on the posture at that time (the contents of TIPO), after performing time waiting for 0.1 second, in order to wait to stop the drive of a tilt motor and for a motor to actually stop, It asks for the data of the position (at this example, it is an equivalent for about 1 and 5 ma+ by motion of a steering wheel) which returned in the down direction from it for a while, and memorizes that value in a tilt top dead center memory. that is, the position memorized by the top dead center memory -- 5 -- a small portion of mechanical marginal positions -- it is this side. Therefore, if a motor is controlled not to cross the position memorized in the top dead center memory, it is lost that V& style part reaches to an actual marginal position in next, and it can avoid a mechanical collision. Next, "1" is set to the limit position setting method flag FLU. Then, Steps 21 and 22 are processed, a tilt motor is driven in the down direction and a tilt motor is suspended after that until it reaches the top dead center memorized now. The bad influence of the excessive stress received by 29 when a tilt mechanism exists in a mechanical marginal position becomes the minimum. Then, since flag FLU is "1" when manual switch SWI is set to ON, it progresses with Step 2-4-6-7-8. In this case, if a tilt position reaches the memorized top dead center, it will progress to Step 13-14 continuously, and will stop the drive of a tilt motor. Therefore, a manual drive is not carried out across the position which the tilt mechanism memorized. However, an electrical overload may be detected before arriving at the marginal position which should be detected, if a foreign substance is caught, for example in a tilt mechanism in the case of the first limit position memory. In that case, incorrect pine Position is memorized by the top dead center memory, and the moving range of a tilt mechanism becomes narrow. then, re-setting mode provides and comes out in this example. When it continues pushing switch SWI and one to dill 1 style specifically reaches a top dead center (memory site), after turning OFF - Responsibility switch SWI, if switch SW1 is pushed again, it will become re-setting mode. That is, if switch SWI is turned off from ON, it progresses with Step 2-4-5-6-15-16, and "1" will be set to manual limit stop flag F2U if a tilt mechanism is a top dead center in Step 16. Although a tilt motor is Suspension(ed) one time by the following step 19, Then, if manual switch SWI is turned on again, it progresses with Step 2-4-5-6-7-8-13, and since flag F2U is "1", it will progress to the next of Step 13 at Step 12, and flag FIU set [ limit position ] will be cleared by "0." Therefore, it is since it progresses with Step 2-4-6-7 in next processing and flag FIU is "0", A tilt mechanism carries out posture change and a limit position again new in a memory is memorized until it skips the check (Step 8) of a top dead center and a tilt mechanism arrives at a mechanical marginal position (i.e., until flag F31 is set to "1"). It is operation of a down, manual Telescopic shortening, and manual Telescopic extension to manual tail 1, Operation of the above-mentioned manual tilt rise is the same, and it is switch SW2 (manual tilt down operation performed by But)! Manual Telescopic shortening operation is performed by operation of switch SW3, and manual Telescopic extension operation is performed by operation of switch SW4. operation of a manual tilt down, manual Telescopic shortening, and manual Telescopic extension -- respectively -- the --b [ 7 ] figure. the -- main processings are shown in thec [ 7 ] figure and 7thd figure. Next, automatic posture setting operation in case a driver gets on and off to a vehicle is explained. In this example, auto switch ASW is ON, and moreover, automatic posture setting operation is performed, when battery voltage is normal. When OFF is equipped with key switch KSW and a key cylinder is not equipped with ignition key 2, away operation which positions Possibility of getting on and off, child nothing, and a steering wheel into an evacuation posture is performed. When ON is equipped with key switch KSW and the key cylinder is equipped with ignition key 2, it is regarded as Possibility of operation and return operation positioned into the posture (memory posture) before evacuating a steering wheel is performed. First, away operation is explained. A regulator output passes along Step 2-3, if an ignition switch is OFF in zero (engine shutdown), and a regulator output is normal, or if ignition switch IGS is ON, it passes along step 2-4-, and progresses to Step 91 of the 7th the e figure anyway. Auto switch ASW has normal battery voltage at ON, and if key switch KSW is OFF, it passes along Step 91-92-93, and progresses to Step 121 of the 7th f figure. Here, the vehicle speed is smaller than 10 km/h, and if input port P1 of CPU is moreover low level L, it progresses with Step 121-122-123, and performs away operation. First, refreshment flag F4 is cleared to "0", and flag FIS set [ limit position ] is checked. If it has not set up, it progresses with Step 125-132-133. At first, since tilt away drive flag F5Ab is "0", it progresses to the following step 134, the drive set of the telescope motor is carried out in the shortening direction, "1" is set to flag F5Ab, and a Telescopic timer is cleared. It is this and a steering wheel. It drives in the direction in which the rotation axis cringes. if a telescopic mechanism arrives at the mechanical marginal position and collides with a predetermined stopper, an electrical overload will be detected by timer interruption processing -- the -- Telescopic stop flag F32 is set to "1" at Step 326 shown inQ [ 7 ] figure. If F32 is set to "1", it will progress to the next of Step 132 of a main routine (the 7thf figure) with Step 138-139. Operation of Step 138, i.e., a Telescopic stop subroutine, is shown in the 7thh figure. The 7thh figure is referred to. In this routine, driving stoppage of the telescope motor is carried out first, in order to wait for a motor to actually stop, time waiting for 0.1 second is performed, and then, flag F5Ab is checked. Since tele score way flag F5Ab is "1" in the above-mentioned case, it progresses to Step 223 next. Since flag F1S set [ limit position ] is "0", it progresses to the 1st order at Step 228, and it is based being the same as that of the case of manual operation on the posture (TEPO) at that time, It asks for the data of the position (in this example, it is an equivalent for about 1 and 5 m+n at the length of an axis) which returned in the extended direction of a steering wheel axis from it for a while, and memorizes that value in the Telescopic shortest point memory. And "1" is set to flag FIS set [ limit position ]. And a telescopic mechanism is driven in the direction which extends an axis until it reaches the top dead center just memorized in the Telescopic iMtln point memory now, i.e., the shortest point. If the position is arrived at, a Telescopic motor will stop. Therefore, a setup of the limit position of the away direction. If it changes into the state of performing away operation even if it does not operate manual posture adjustment specially, it will be carried out automatically. The situation where a limit position remains not set up by this for a long period of time since he has forgotten adjustment is avoided. It returns to the 7thf figure and continues explanation. If 0.3 second is exceeded after starting away operation and starting the drive of a telescopic mechanism (i.e., if the value of Telescopic timer T2 exceeds 0.3 second), it will progress with Step 135-128-129-130. Since the tilt mechanism has stopped at first, tilt away flag F5Aa is "0" here. Therefore, it progresses to Step 131 at the 1st order. In Step 131, the drive set of the tilt motor is carried out in the rise direction, "1" is set to tilt away flag F5Aa, and tilt timer T1 is cleared. That is, in this example, when the drive start of the telescopic mechanism is first carried out in the shortening direction and 0.3 second passes at the time of away operation, the drive start of the tilt mechanism is carried out in the rise direction. Such a time lag is given in order to lose the influence of the incoming current at the time of the energization start of an electric motor. namely, -- if the energization start of a plurality of electric motors is simultaneously carried out since the very big transitional current at the time of an energization start (incoming current) flows through an electric motor, total of the current which flows through a battery will reach to an extreme temporarily -- The -- it becomes large and malfunction arises in an electric circuit by this. However, even if it drives a plurality of electric motors simultaneously by shifting the timing of an energization start by this [ required for transitional current to fully be stabilized / temporal aspect ], the maximum of a current value is held down to a comparatively small value (refer to the 9th figure). The time taken to complete posture adjustment, i.e., evacuation operation, by this compared with the case where it adjusts in order if posture adjustment of a telescopic mechanism and the tilt mechanism is simultaneously carried out on substance is shortened by the abbreviated half. Like this example, at the time of evacuation (away), if the drive start of the telescopic mechanism is carried out previously, and the drive start of the tilt mechanism is carried out continuously, a desirable result will be obtained. That is, if the direction of shortening operation of a steering wheel axis carries out operation of a telescopic mechanism previously since a feeling of opening can be given with a driver rather than the case of tilt operation, a feeling of freedom can be early given to a driver. If at least Limiter1~ arrives at the shortest position which the posture of the telescopic mechanism memorized after finishing flag FIS on a set is set to rlJ, It progresses to the next of Step 126 of the 7th f figure at Step 127, the drive of a Telescopic motor is stopped, and tele score way drive flag F5Ab is cleared to "0." When the top dead center of the tilt mechanism is not memorized. By performing away operation, a mechanism part reaches to a mechanical marginal position. in this case -- an electrical overload is detected by timer interruption processing -- Step 319 of Drawing 7 -- tilt stop flag F31 -- "1" -- set To 9 To. If flag F31 is set to "1", it will be Step 129 of the 7th f figure, next will progress to Step 136. Processing of Step 136, i.e., a tilt stop subroutine, is an example in detail to the 7thg figure. The 7thg figure is referred to. In this routine, driving stoppage of the tilt motor is carried out first, in order to wait for a motor to actually stop, time waiting for 0.1 second is performed and flag F5Aa is checked to the 5th order. In the above-mentioned case, since tilt away flag F5Aa is "1", it progresses to Step 203 at the 9th order. Since the limit position setting method flag FIU is rOJ, it progresses to the 1st order at Step 208, it asks for the data of the position which returned in the down direction from it for a while on the basis of the posture (TIPO) at that time like the case of manual operation, and memorizes the value in a tilt top dead center memory. And "1" is set to the limit position setting method flag FIU. A tilt mechanism is driven to an opposite direction (the down direction) even in it until it reaches the top dead center just memorized in the tilt top dead center memory now. If the position is arrived at, a tilt motor will stop. Therefore, as for a tilt mechanism, even if it does not operate manual posture adjustment specially, a setup of the limit position of the away direction will be automatically performed, if 7 Cotton candy operation is performed. If a limit position is memorized by a framework, manual posture adjustment, or automatic posture setting operation, Unless abnormal circumstances arise, flags F31 and F32 are not set to "1", therefore posture adjustment of a tilt and a telescopic mechanism is ended in away operation in the place which reached the top dead center and the shortest point which were memorized. If a telescopic mechanism reaches the shortest point and a tilt mechanism reaches a top dead center, evacuation operation of a steering wheel will be completed. Operation of a sheet is mentioned below. Next, return operation is explained. When auto switch ASW has normal battery voltage at ON. If key switch KSW is set to ON, it will pass along Step 91-92-93, will progress to Step 98, and will perform return operation. First, a standby timer is cleared. Next, the limit position setting method flag FID is checked. If it has not set up, since tilt return drive flag F5Ra is "0" at Step 99-106-107 and the beginning to follow, zero-order step 108 is performed. In this step 108, the drive set of the tilt motor is carried out in the down direction, "1" is set to flag F5Ra, and tilt timer T1 is cleared. Now, a steering wheel is driven toward the direction of a bottom dead center from a retreating position, i.e., a top dead center. If a tilt mechanism arrives at the mechanical marginal position (bottom dead center) and collides with a predetermined stopper, an electrical overload will be detected by timer interruption processing, and flag F31 will be set to "1" at Step 319 shown [ 7th ] in a figure. If F31 turns into "1", it will be Step 106 of the 7th the e figure, next will perform Step 112, i.e., a tilt stop subroutine. In this case, since flag F5Aa is "0", it progresses with Step 201-202-211. In this case, since the limit position setting method flag FED is "0", it progresses to Step 212 at the 1st order. In Step 212, it asks for the data of the position (this example 5 about 1 mm) which returned in the direction of [ above it ] for a while on the basis of the posture (TIPO) at that time, and memorizes that value in a tilt bottom dead center memory. And a tilt mechanism is driven toward the direction of a top dead center until it reaches the bottom dead center just memorized in the tilt bottom dead center memory now. A tilt motor will be suspended if a bottom dead center is reached. Therefore, a bottom dead center setup of a tilt mechanism will be automatically performed, if it sets to the state of performing return operation even if it does not operate manual posture adjustment specially. the -- it returns toe [ 7 ] figure and continues explanation. If 0.3 second passes after starting return operation and starting the drive of a tilt mechanism (i.e., if the value of tilt timer T1 exceeds 0.3 second), it will progress with Step 109-114-103-104. Since the telescopic mechanism has stopped at first, tele Scolli turn drive flag F5Rb is "0" here. Therefore, it progresses to Step 105 next. In Step 105, the drive cent of the Telescopic motor is carried out in the direction which extends a steering wheel axis, "1" is set to flag F5Rb, and Telescopic timer T2 is cleared. That is, in this example, when the drive start of the tilt mechanism is first carried out in the down direction and 0.3 second passes at the time of return operation, the drive start of the telescopic mechanism is carried out in the extended direction. Such a time lag is given like the time lag at the time of above-mentioned away one in order to lose the influence of the incoming current at the time of the energization start of an electric motor. Like this example, at the time of a return, if the drive start of the tilt mechanism is carried out previously and the drive start of the telescopic mechanism is carried out later, a desirable result will be obtained. That is, the feeling of oppression which the direction where it delays the start of a return posture setup of a telescopic mechanism rather than a tilt mechanism since the extended operation of a steering wheel axis gives a feeling of oppression to a driver rather than down operation of a tilt mechanism gives to a driver is small. When the longest point of the telescopic mechanism is not memorized, a mechanism part reaches to a mechanical marginal position (the longest position) by performing return operation. In this case, an electrical overload is detected and Telescopic stop flag F32 is set to "1" by timer interruption processing at Step 326 of the 7th the Q figure. If flag F32 is set to "1", it will be Step 103, next will progress to Step 110. In the Telescopic stop subroutine of Step 110, in order to wait to suspend a Telescopic motor and for a motor to actually stop first, time waiting for 0.1 second is performed and then flag F5Ab is checked. Here, since it is among a return, flag F5Ab is "0." Therefore, next it progresses to Step 231 and checks flag FIL set [ limit position ]. At first, since FIL is "0", it progresses to Step 212 at the 1st order, and is Mu. In Step 212, it asks for the data of W (this example about 1.5 mm) to the extent that it returned in the shortening direction from it for a while on the basis of the posture at that time (TEPO), and that value is memorized in the Telescopic longest point memory. And a telescopic mechanism is driven toward the shortening direction until it reaches the longest point just memorized in the Telescopic longest point memory now. A Telescopic motor will be suspended if the longest point is reached. Therefore, the best point setup of a telescopic mechanism will be automatically performed, if it sets to the state of performing return operation even if it does not operate manual posture adjustment specially. Since it will progress with Step 98-99-100 in processing of the 7th the e figure by a framework, manual posture adjustment, or automatic posture setting operation if a limit position is memorized, the drive stops in the place which arrived at the memory site before a tilt mechanism evacuating, i.e., the usual driving posture. Since flag FIL set [ limit position ] is "1", it progresses with Step 109-114-102, and confirms whether to be the memory site before the posture of a telescopic mechanism evacuating, i.e., a driving posture, at Step 102, and the drive stops in the place which reached the driving posture. That is, it is only 1 time immediately after power supply ON that a tilt mechanism and a telescopic mechanism reach to a marginal position in return operation, and limit positioning operation is performed. If both a tilt mechanism and a telescopic mechanism reach a memory posture, return operation of a steering wheel will be completed. It is since it judges whether the key cylinder is equipped with ignition key 2 by key switch KSW in this example and automatic posture setting operation is performed by that result, Even if ignition key 2 is turned and it turns ON an ignition switch, before inserting ignition key 2 in a key cylinder, starting automatic posture setting operation and completing the operation, KSW is not come by off, therefore automatic posture setting operation does not stop in the middle of posture adjustment by operation of Engineering key. the [ next, ] -- posture adjustment of a sheet is explained with reference toj [ 7 ] figure. The state of door switch DSW is checked first. If door opening is detected, a sheet will be positioned into a getting-on-and-off posture. First, "1" is set to away flag F5Ac at Step 162, and the drive set of the sheet motor M1 is carried out in the direction in which a sheet goes to a doorway. If a sheet posture is supervised and the position becomes a predetermined getting-on-and-off posture, it will progress to Step 161, sheet motor M1 will be turned off, a sheet timer will be cleared, and See 1~away flag F5Ac will be cleared to zero. If an electrical overload is detected during the drive of a sheet, F33 is set to "1" for a See 1-stop flag. In that case, it progresses to step PR7 and the cent of the sheet motor M1 is carried out to OFF, like the case of other mechanisms, inversion flag F6c is set to "1", the drive set of the sheet motor M1 is carried out in the inversion direction, and if an inversion flag is set to "O", motor M1 will be suspended. a door -- closed (it is not fully closed) -- if it detects, it will judge with operational status, it will progress to Step 156, "1" will be set to sheet return flag F5Rc, and the drive set of the sheet motor M1 will be carried out in the direction in which a sheet goes to the position for operation. If a sheet posture is in agreement with a memory site, i.e., the position for operation, sheet motor Ml will be set to OFF at Step 155, a sheet timer will be cleared, and sheet return flag F5Rc will be cleared to "0." If an electrical overload is detected during the return drive of a sheet posture, sheet motor M1 will be set to an inversion like the case of other posture setting operations, and if predetermined conditions are fulfilled, motor M1 will be set to a stop. Although the state of the existence of the vehicle speed, a parking brake, and an ignition key is performing starting of automatic posture setting operation (away one and return operation) by whether it is in agreement with predetermined conditions in the above-mentioned example, various things as this condition can be considered. Then, about the modification example which changed this condition, it is Drawing 11. It is respectively shown in Drawing 12, Drawing 13, and Drawings 14, 15, and 16. These figures change a part of processing of the 7th the e figure of the above-mentioned example, and others are the same as that of the above-mentioned example. In the example of Drawing 11, the conditions of an automatic setup of a steering wheel posture (a tilt and Telescopic) are limited to when neutral switch NLS of a self-@ gearbox is ON, and return operation or away operation is performed according to the existence of ignition key 2. In the example of Drawing 12, the conditions of an automatic setup of a steering wheel posture are limited to when neutral switch NLS is ON, and away operation or return operation is performed according to OFF/ON of accessories switch ACC8. In the example of Drawing 13, the conditions of an automatic setup of a steering wheel posture are limited to when neutral switch NLS is ON, and away operation or return operation is performed according to OFF/ON of ignition switch ■GS. In the example of Drawing 14, the conditions of an automatic setup of a steering wheel posture are limited to when parking position switch PKS of an automatic shift is ON, and return operation or away operation is performed according to the existence of an ignition key. In the example of Drawing 15, the conditions of an automatic setup of a steering wheel posture are limited to when parking position switch PKS is ON, and 7 Cotton candy operation or return operation is performed according to OFF/ON of accessories switch ACC8. In the example of Drawing 16, the conditions of an automatic setup of a steering wheel posture are limited to when parking position switch P'KS is ON, and away operation or return operation is performed according to OFF/ON of ignition switch rGS. the -- the relation between each position of the ignition key on a key cylinder and ON and OFF of each switch is shown in 1. Oa figure -- the -- the relation between the shift lever position of an automatic shift and ON and OFF of each switch is shown inb [ 10 ] figure. The various above-mentioned modification examples have the characteristic strong point respectively.

[Effect] As above, by the present invention, after influence of incoming current at the time of an energization start of a driving means (electric motor) of one system is lost, a driving means of another system is energized. Therefore, even if it drives a plurality of mechanisms simultaneously on substance, a period which incoming current produces does not overlap and malfunction by a voltage drop does not arise. Since a plurality of mechanisms are simultaneously driven on substance, the time which posture adjustment takes is shortened.
