NAME OF THE INVENTION: "A system adapted to one or more electrically propulsive vehicles." (Detecting arrangement.)

TECHNICAL FIELD OF THE INVENTION

The present invention relates generally to a detection arrangement of a track in a stretch of road and its road sections, related to an electrically propelled vehicle adapted system, and more particularly to such a system where, inter alia, one or more batteries and / or a battery set, for power adjustment and energy storage, is intended to be able to propel the vehicle rolling along the stretch of road.

Systems of this kind are based on the utilization of a stretch of road where the upper surface of this stretch of road has at least one track and into which two or more parallel electrical and voltage conductive conductors are inserted, which are preferably formed with exposed and uninsulated surface sections.

In accordance with the instructions of the present invention, such a system shall comprise: "a" a plurality of divisible, total sections of road, each of which is assigned one or more electrically conductive conductors, connectable, via a switch, to stationary electrical stations, serving as a the vehicle exterior energy source, in order to allow to charge vehicle-related batteries and / or the battery set, but primarily via the battery set let the vehicle run along the stretch of road and its road sections and "b" one or more, via their electric motor or a plurality of mo533 982 drivers, drivable vehicles and where, respectively, vehicles shall have an effect regulating control circuit, for the creation of a selected and required propulsive power and / or a speed adjustment and / or regulation.

The invention aims to be able to have an application for road stretching in the form of public and individual roads and along its road sections, but can also come to use in industrial plants, with different requirements for power requirements and energy requirements.

The invention relates to, inter alia, simultaneously with an energy charge of the battery set from the external energy source, supply the power and energy that will be required for a selected power demand for the vehicle's upward and upward gradient section.

More particularly, the present invention provides such a system in which a non-track vehicle, such as a truck, during its performance along selected road sections with its vehicle-assigned battery set, can be supplied with a supplementary energy, such as from the external energy source or from a vehicle-related energy source, such as a diesel generator.

In this regard, the present invention proposes a "first" vehicle-related power source, such as a diesel generator, a "second" vehicle-related power source, such as a battery set, and a "third" vehicle separate and external power source, such as voltage-adjustable electric two or more conductors embedded in tracks. successive sections of road, and wherein the conductors of a selected road section are electrically insulated from the corresponding conductors of an adjacent (present or subsequent) section of the road.

The present invention is based on the fact that two or more conductors are embedded in one track or in each track in its road section and where the track (non-conductors) extends continuously from road section to road section.

The voltage assigned to these voltage-adjustable conductors may be an AC voltage (with a vehicle-related rectifier) ​​or a DC voltage. When choosing a direct voltage, one conductor can be positive while the other conductor can be

533 982 negative and an additional conductor assigned ground potential or 0 potential, whereby the vehicle can be operated at double the voltage value.

When alternating voltage to the conductors for the road sections, this can advantageously be arranged in a counter phase and symmetrically around an earth potential or O potential.

The motor intended for driving the vehicle may be a direct current type or alternating current type, in which case the motor shall be preceded by an inverter.

BACKGROUND OF THE INVENTION

Methods, arrangements and constructions, related to the above-mentioned technical field and nature, are previously known in a variety of embodiments.

In the case of electrically driven vehicles, these can advantageously be categorized as track-bound vehicles ”or as“ non-track vehicles ”.

"Tracked vehicles" are driven along their stretches of road and sections of roadways inserted or via the exposed parallel rails of the grinders, which control the fixed wheels of the vehicle.

"Non-tracked vehicles" are driven along their stretches of road and sections of road over a drivable and carried along the sections of the road via a vehicle belonging to the control equipment.

The present invention is based on and is intended to be utilized in the latter category and technology, and is primarily intended to be able to apply to heavy goods vehicles, with or without coupled trailers, where known, by patent publication US-4,129,203. A, a vehicle-related arrangement for, up and down and sideways, cause the vehicle to underlie contact springs for mechanical and electrical co-operation with or out of co-operation with the non-insulated surface sections of the road sections of voltage-controlled electrical conductors (14).

Here, use is made of an insulator (16) within a channel (18) which supports the conductors in the form of rails (14). A cover plate (20) formed with a slot (12) is removably attached

533 982 to the upper and opposite wall portions of the duct (18), where this cover plate (20) is aligned to a plane adjoining the upper surface (22) of the road section.

Figures 2 and 3 of the aforementioned patent publication describe a vehicle-related table (98) and to which table is pivotally attached (94, 96, 99) an arm (10). The sensors (30) associated with the table (98) generate signals which, with respect to phase position and size, indicate the direction and distance from a rotational shaft (99) to the slot (12) in the cover plate (20), which is based on changes in an generated magnetic field. Via a designated mechanism (31), the table (98) and the arm (10) can be driven by a motor (32) between predetermined limits and positioned limit switches (40, 41).

By patent publication WO 93/10995-A it is previously known a system for driving along electrically drivable vehicles along a stretch of road and its sections.

Figure 9, in this patent publication, indicates the principle structure of the system.

Here it is disclosed that the road section (14) and its road sections are provided with electrically conductive road sections (300a - 300f), where a road section can be considered to correspond to a road section.

The vehicles (310) have an electric motor (320) and two (312, 314) or three (312, 312 'and 314) underlying contact springs, adapted for mechanical and electrical contact with the electrically conductive conductors, the length of which is adapted to correspond to a selected length (identically equal lengths) for utilized road sections or sections.

The electrically conductive conductors within the road sections (300a - 300f) are positioned one after the other with a mid-range free space (302a - 302e), thereby preventing a short circuit via trailing contact springs (312, 312 ', 314).

Here, each other road section (300b, 300d, 300f) is connected continuously to a reference voltage (ground potential) while the other road sections (300a, 300c and 300e) are either directly connected to a DC voltage source (440) or via a

533 982 coupling means (304a, 304b, 304c) connectable to any suitable electrical power source (308) when a vehicle is nearby.

When an embodiment with three contact springs is used, the distance between them must be chosen so that two or three contacts are always in an electrical contact with two opposite polarity-exhibiting wall sections and that neither of the two contacts should be able to short the free space (302a-302e) between two nearby sections.

The system here requires for its function specially designed vehicles (310), where a selected distance between front (314) and rear (312, 312 ') contacts must be identically equal and further selected slightly longer than the road sections (300b, 300d) equal lengths.

Thus, specially designed vehicles with front and rear contacts are required and where each of the used road sections (300a - 300f) is to be chosen with equal lengths and oriented one after the other in the vehicle's direction of travel with equally free and intermediate spaces (302a - 302e).

The patent publication generally indicates the presence of a single stressed conductor or rail within a road section (p. 5, lines 11-13), and that a vehicle should be able to call voltage to a present road section (p. 5, lines 19-21; p. 6, line 710; page 8, lines 28-32).

Furthermore, it is contemplated that voltage-adjustable rails (16) should be provided with lateral drainage grooves (page 9, lines 1-4).

An absence (or presence) of an activation signal must be able to affect a control unit (38) (page 8, lines 23-27).

The required distance between vehicle-related contacts is given on page. 10, row, 17-20 and a utilization of activity initiating radio signals is proposed on page. 11, lines 2-4 and p. 14, lines 1-16.

533 982

It is further suggested, on p. 15, lines 21-23 and p. 16, lines 1-15, utilizing a Hall element (240) and its connection to an amplifier (246). Alternatives to this are further illustrated on page 17, lines 3-9.

It is also known to electrically drive a vehicle along a stretch of road by means of an inductive energy transfer effective between a vehicle and an underlying road section.

As an example of this prior art reference is made to the contents of patent publications US-3,914,562-A and US-4,007,817-A.

The present invention concentrates on a detection arrangement for detecting the occurrence and orientation of a track oriented along a stretch of road and its road sections and with its upwardly open tracks connecting to each other from road sections to road sections with two or more parallel electrical conductors, such as shaped with uninsulated surface sections within each road section, and relates to the structuring of the detecting arrangement to allow interaction between a vehicle-related pantograph and the track, utilizing a magnetic field, to generate within the road section and detectable by vehicle-related coils whose output signals are processed by a control equipment.

DESCRIPTION OF NOW PROPOSED EMBODIMENTS.

It should be pointed out at the outset that in the following description of presently proposed embodiments which exhibit the significant features of the invention and which are illustrated by the figures shown in the following drawings, we have chosen terms and a particular terminology in order to primarily to clarify the concept of invention itself.

533 982

However, it should be taken into account in this context that the terms chosen here are not to be construed as limiting only to the terms used and chosen here, but it should be understood that any such term chosen shall be interpreted so that it will in addition include all technical equivalents, which function on the same or substantially the same way, thereby being able to achieve the same or substantially the same intention and / or technical effect.

Thus, with reference to the appended figures, the basic conditions of the present invention are shown schematically and in detail in which the significant features of the invention are concretized, by the presently proposed and subsequently described embodiments.

Thus, Fig. 1A shows one, for an electric and propulsion of one or more batteries or a battery set, the forwarding of the vehicle 1 along a stretch of road 2 and its road section 2a 1 and 2a 1 'adapted system "S".

The vehicle 1 here is made exterior of a Ford-Ford, but this is here converted to a battery-powered vehicle, with an access to an external energy source, designated "si", "111".

The vehicle 1 according to the invention should then comprise a control equipment not shown, so that a driver F (not shown) can drive and steer the vehicle 1 along said road section 2 and its road section 2a1. The vehicle 1 could also include a gearbox and other parts and details required for the vehicle's performance, but as these parts are well known to one of ordinary skill in the art, they will not be described in detail.

However, an electrically driven vehicle 1 does not need a gearbox as speed control and power take-off can be done via known electrical and electronic circuits.

Figure 1B shows, in the same way as in Figure 1A, an electrically propelled truck 1b with coupled trailer 1c along the road section 2, 2a and its road section 2a1.

533 982

The figure 1C now clearly shows two vehicle-related energy sources, designated Ί "and" II ", a" first "in the form of a diesel generator" G ", a" second "in the form of a battery or a battery set" B ", and a third "Energy source" IIΓ in the form of a vehicle external energy source, here formed as, via coupling means or switches, voltage-adjustable parallel conductors or rails, recessed into grooves and a cavity in the roadway or stretch of road 2.

These in Figure 1C are coordinated to a vehicle-related control circuit 100, which, depending on an applied power to an electric drive motor 5, allows all or a combination of the power-supplying energy sources T, 11 "III". The power control is illustrated here as a gas pedal 100a, whose movement up and down is coupled to a control circuit "R2" within the control circuit 100, which in turn comprises one, power and energy between the energy sources, distributing circuit "R1".

Figure 1D illustrates in a P / t (power / time) diagram how a full power or reduced power can be distributed and transmitted for the passage of the vehicle along different road sections 2a of a road or road 2 using circuit R1 and control circuit "R2 ".

Between the times ti-12 it is basically illustrated how a full power output from the three energy sources "I", "II" and III "can be realized, with the power output from the energy source I" illustrated at the top, the power output from the energy source "II" illustrated below (dashed lines) and the power outlet for the energy source H1 ”illustrated below.

Between the times t₅ - t © illustrates in principle a reduced power output from the energy sources "II" and "III".

During this period of time, full power can be obtained from the energy source ΊΓ and a small excess can be allowed to maintain the charged battery set "II", "B".

533 982

The invention is based on the fact that the battery set B "and the second power source" 11 "must first supply the motor 5 via the distributing circuit R1" and for this purpose the battery set "B has stored an energy capable of driving the motor 5 at full power. .

Battery set "II"; B "shall be primarily maintained through the energy source" III "; "S1" and in the alternative is maintained or charged via the energy source "I".

The energy from the energy sources T and "III" can be selected at 5-30% of the energy assigned to the energy source "II"; "B", such as about 25%.

The supply voltage to the motor 5 can be selected at +400 VDC and -400 VDC, ie the voltage value 800 VDC.

The system "S" proposed according to the invention should then comprise in the first place: "a" one or more, via each electric motor 5 or motors, electrically driven vehicles 1,1b and where, respectively, vehicles exhibit an effect distributing and / or regulating control circuit "R1" within the control circuit 100, for the creation of the required power and / or speed control via the control circuit "R2" and the accelerator pedal 100a.

The required power output must be provided primarily by the vehicle exterior energy source "II"; "B" and which must be secondary to maintenance charge from the energy source "III"; "S1". The road section 2 is divisible into road sections 2a (2a1,2a2, 2a3; 2a1 ', 2a2' and 2a3 '), each of which should advantageously be assigned an external energy source "III", here illustrated as a number of electrical stations "s1.

The vehicle exterior third energy source "III"; "S1" and / or vehicle-related first energy source "I"; "G" can be used one or both, in order to supplementally charge the vehicle's battery set "II"; "B" during a custom time sequence of power outputs from this battery set.

It also falls within the scope of the invention in addition to driving the vehicle 1 via the battery sets II; B "and during a supplementary charge of the battery set" II "; "B" along the road sections and the stationary electrical stations "sT 'or the energy source" III ", for the vehicle 1's transmission over the road section 2a1, an additional additional power and energy can be supplied via the vehicle-related energy source" I "; "G.

Figure 2 shows, in principle, an electrical / mechanical coupling arrangement "K" related to a vehicle 1, (1b) with a schematically shown control equipment 10, for controlling a vehicle-associated pantograph 4 towards and to an electrical contact with pairs of voltage-adjustable wires, in the form of rails. 4a, 4b, for a possible common parallel operation of an electric motor 5, from the battery set "II"; "B" and / or from stationary station "III"; "S1", and / or from the diesel generator "I", "G".

The pantograph 4 is here related to a carrier 6 which is vertically arranged up and down via a first electric auxiliary motor 7 and laterally is movably arranged back and forth via a second electric auxiliary motor 8.

The means and control of the auxiliary motors 7, 8 required for this movement by means of sensors are not shown in detail, but are in principle previously known and obvious to one of ordinary skill in the art.

The auxiliary motor 7 and the auxiliary motor 8 are both operable in a reciprocating motion, wherein a first movement is activated via a first signal on a first conductor 7a and a first signal on a first conductor 8a, while a second (opposite) movement is activated via a second signal on the conductor 7a and 7a, respectively. 8a, while the instantaneous setting positions of the motors 7, 8 and the carrier 6 are evaluated by one or more sensors not shown and indicated by a generated signal on a second line or conductor 7b and 8a respectively. 8b.

These signals on the first conductors 7a, 8a are generated in a central unit or control circuit 100 with a control equipment 10 and signals on the second conductors 7b and 8b are generated within the same central unit 100, utilizing position sensors (not shown).

The central unit 100 with the control equipment 10 is a complex unit, which via a sensor 16 it must be able to detect the presence and orientation of conductors 4a, 4b and then lower the pantograph 4, via the auxiliary motor 7, to an electrical contact with these conductors 4a, 4b, which are here illustrated as voltage-set or vice versa.

Via a connection 10a to the central unit 100 and its control circuit "R2", the power to be supplied via the control circuit "R1" to the motor 5. For this purpose, the control circuit "R1" is directly controlled by a gas pedal 100a (Fig. 1C) in order to via the control circuit R2 ”to supply the required power to the motor 5.

In the shown position, the pantographs 4 allow current and voltage to be transferred from the energy source "III" to a power and energy distributing control circuit "R1". This or another control circuit "R2" senses via the central unit 100 the power demand of the motor 5 and primarily allows the motor 5 to supply the power it needs according to the input signal on the connection or line 10a and the output signal on the connection or line 10b thus generates the stationary system. "ST", "III" are charged and supplemented with power and energy requirements via the battery set "II", "B.

A parallel connection of the vehicle externally extracted power III "," s1 "and the vehicle internally generated power" I "," G "and / or" II ", B" can be realized here via the control circuits "R1" and "R2".

Via the line 10a, information is provided to the central unit 100 on a desired speed and associated power for the vehicle 1 and via internal circuits not shown and the function R2 "; "10 is affected via line 10b control circuit R1".

Figure 3 shows, in an end view, a vehicle 1 (1 b) with its downwardly directed pantographs 4 in a mechanical and electrical interaction with the two conductive conductors or rails 4a, 4b, assigned to the section of road 2aT, and an earth connection 4c.

Figure 4 shows an electrical connection arrangement ”ΚΓ where road sections on road sections 2a 1, 2a2 and 2a3 respectively. 2aT, 2a2 'and 2a3' with their station after station "s1", "s2", "s3" respectively. "S1" s2 '"and" s3' ", can be energized and energized from one and the same parent charge source III, 42, via switches or coupling means 43a, 44a, and 45a for one of the road sections 2a and 43a ', 44a' and 45a ' for the opposite road section 2b, as a vehicle 1 will pass along the electrically spaced, but longitudinally aligned, sections of the road sections 2a, 2b.

For this, a number of switches or switching means (switches) are required for a switching on and off of stations "s1", "s2" ...., where this switching on and off can be done via stationary sensors related to the road section (not shown).

The present invention and its detection arrangement will now be described in more detail with reference to Figures 5 to 11.

Thus, as shown in FIG. 5, on an arrangement in which lateral said track 51,52 is arranged in the carriageway 2a1 or in the duct 30, one or more electrical conductors L1, L2, through which is arranged to pass a direct current, to generate a magnetic field and / or inserted in place of these conductors L1, L2 permanently magnetized magnets, to generate said magnetic field.

A coil Sp1 related to the vehicle 1 is adapted to allow, by its relative movement across the tracks 51, 52 to detect the magnetic field "B" variation and to influence the pantograph 4 via associated auxiliary motors 7, (8), for cooperation with the groove and the electrically adjustable conductors 4a, 4b inserted in the bottoms of the grooves 51, 52.

The distance "h between the conductors L1, L2 and / or the magnets related to the carriageway 2a1 and the vehicle-related coil Sp1 is adapted to below 15 cm, such as between 10 and 1 cm.

The reference numeral "d" indicates a selected distance between the conductors L1, L2 and the reference numeral "-x" and "+ x" is intended to indicate the distance that the coil Sp1 takes from a central plane "0" for the grooves 51 and 52 or the conductors L1, L2 and to be able to determine the orientation of the grooves 51 and 52 and to be able to bring down the contact means 4 to cooperate with the rails 4a, 4b, or 4c, respectively.

Figure 6 then illustrates the magnetic field's distance dependence ('' -x '; + x') variation B 'for three different heights' h', where it can be seen that the coil Sp1 indicates a minimum at the central plane '0'. The conductors L1 and L2 are fed with equal currents and in opposite directions, giving the waveforms of Figure 6.

533 982

Figure 7 illustrates that said coil consists of two coils Sp1, Sp2, oriented one after the other across the driving direction of the vehicle 1.

The reference numerals "-x" and "+ x" are intended to indicate the distance taken by the coils Sp1, Sp2 from a central plane 0 for the tracks 51 and 52 or the conductors L1, L2 and to be able to determine the orientation of the tracks 51 and 52 and to be able to bringing down the contact means 4 to cooperate with the rails 4a, 4b, or 4c.

The figure 8 then illustrates the magnetic field's distance dependence ("-x"; "+ x) variation" B "for three different heights h", where it is shown that the coils Sp1, Sp2 indicate a maximum at the central plane "0". The conductors L1 and L2 are fed with equal currents and in opposite directions, which gives the waveforms of Figure 8 when the coils Sp1 and Sp2 are counter-coupled.

The control equipment 10 is adapted to, as the magnetic field has increased and starts to decrease, as shown in Figure 6, to actuate the auxiliary motors 7, (8) to lower the pantograph 4 to contact with voltage conductors 4a, 4b.

The control equipment 10 is further adapted that, when the magnetic field B "for the coils Sp1 and Sp2 has increased and starts to decrease towards" 0 ", according to Figure 8, let calculate or wait for a maximized magnetic field B" and actuate the auxiliary motors 7, (8) to lower the pantograph. 4 for contact with voltage conductors 4a, 4b.

The control equipment 10 is also adapted to allow, via circuits, to distinguish a minimum value or a maximum value, valid for a false identification of a track from false values.

The two coils Sp1, Sp2 are oriented at the same vertical distance h "from parallel electrical conductors or magnets, related to the grooves 51, 52 and / or the road section 2a1.

The principle of the invention is to relate to the realization that by placing cables L1, L2 in the road section 2a1, a detector 16 adjacent the pantograph 4 can detect magnetic fields from the coil Sp1 in Figure 5 or from the coils Sp1; Sp2 in Figure 2, thereby locating the tracks 51, 52.

To avoid mistakes, use a frequency that does not normally occur. It is important to avoid grid frequency and harmonics to the grid frequency. In this way, the detectors can be made very selective by filtering narrow band with a high gain.

The figure 6 thus intends to illustrate the variations of the magnetic field at three different distances and height "h" from the live conductors L1, L2, with h "selected at 10 cm, 3 cm and 1 cm, with increasing B-value.

It can be difficult to determine from this data when the contact 4 is to be lowered into the grooves 51, 52. Particularly troublesome is that the field B "increases and then decreases from" -x "to 0" and therefore increases with "+ x". It is at a minimum field strength that the contacts 4 should be lowered.

By introducing two coils Sp1, Sp2, as shown in Figure 7, a more sophisticated assessment can be made.

Figure 8 is intended to illustrate the subtracted sum of the magnetic fields in two coils Sp1, Sp2, with the same distance from each other as the grooves 51 and 1, respectively. 52 width in the road section 2a 1.

Maximum magnetic field "B" is obtained when the contact 4 and the coils Sp1, Sp2 are in the middle of the tracks 51; 52. This increases the safety of bringing down contacts 4 at the right time.

However, in some cases it can still be difficult to find the absolute maximum value, as it cannot be ignored that there can be local maximum values ​​at the wrong location.

The following function is studied;

f (x, li) = + B2 (x, / i) l / | F (x, h) |

533 982 where: B1 is the field of detection coil Sp1, as a function of distance from track 51 and height above road section 2a1;

B2 is the field of detection coil Sp2, as a function of distance from the groove 51 and height above the road section 2a1; and

B is the sum of the two fields;

For example, the waveform of Figure 8 can be transformed into a waveform of Figure 9, where the coils Sp1 and Sp2 are connected in series.

Figure 9 then shows the function at 10 cm, 3 cm and 1 cm height h over the runway 2a1 and gives distinct values ​​"B2" under a reference (ref).

As is evident, the function gives a markedly low value in the vicinity of the value "0" and the track 51 and 2 respectively. 52. This can be used to remove the local maximum values.

Form a new function according to:

= 1 if f (x, h) &lt;uref fl (x, K) = 0 if f (x, h.)&gt; Uref.

According to Figure 10, this gives a high value near the groove 51 and 1, respectively. 52, but "0" further on the x scale from the "0" point.

The value "clockwise is selected so that the value becomes" 0 "at the local maximum values. However, the value “uref” can be selected within a fairly wide range.

The function f1 (x, h) is multiplied by the B fields, from the two coils Sp1, Sp2 below the "uref" value in Figure 9 to form the graph of Figure 10.

Apparently, a distinct signal is obtained very close to the center of the tracks 51 and 1 respectively. 52. The control must now make sure to look up the maximum value and lower the contact there. 52 one to lie exactly right without the risk of confusion with false values.

Thus, Figure 11 is intended to illustrate, in a perspective view, the embodiment of Figure 7.

533 982

It will be appreciated that Figure 11, in a slightly modified embodiment, may come to use in the embodiment of Figure 5.

Paired pantographs 42a, 42b for a second groove 52 are oriented immediately above groove 52.

The bottom of the groove 51 carries the voltage-adjustable or voltage-fed conductor 4a, while the bottom of the groove 52 carries the conductor 4b.

According to the invention, and with reference to the embodiment of Figure 7, the presence of two coils Sp1 and Sp2, which are fixedly related to the pantographs 41a, 41b and 2 respectively, are indicated. 42a, 42b and shall follow horizontally in the horizontal movement of the pantographs to detect the occurrence and instantaneous position of the tracks 51 and 52 related to the carriageway 2a 1.

The sensed signals from the coils Sp1 and Sp2, which are dependent on the instantaneous magnetic field from the conductors L1 and L2, are supplied to the control equipment 10 as input signals.

Via a calculation circuit 10a1 and taking into account stored criteria in memories, an output signal is generated to actuate the auxiliary motor 7 to lower the pantographs 41a, 41b respectively. 42a, 42b down towards and for electrical interaction with conductors 4a, 4b.

The calculation circuit 10a1 can also generate an output to actuate the auxiliary motor 8.

In the memory 10a2 are stored magnetic fields depending on the horizontal distance from the track, in the memory 10a3 is stored the vertical distance "h" and in the memory 10a4 other relevant criteria.

The invention is, of course, not limited to the exemplary embodiment described above but can undergo modifications within the scope of the inventive idea illustrated in the following claims.
