Audio system with automatic setting of user-dependent system parameters

The invention relates to an audio and / or navigation system of a motor vehicle with a control unit for setting the system parameters by a user.

Audio systems are among the most widely used information and Comfort systems in motor vehicles. They have an operating unit for Setting on different system parameters. These include, for example, the setting of the radio channel, the volume or the Sound. Furthermore, for example, the automatic insertion selectable traffic announcements during running CD or cassette mode be.

Navigation systems are among the most modern information systems in Motor vehicles. After entering a destination, the system calculate a Driving Directions and enter while driving the necessary instructions to the Rider. For dynamic route selection, that is a route selection taking into account the changing traffic conditions, can the navigation systems to be connected to an audio system. hereby Broadcasting can broadcast traffic information via the audio system supplied directly to the navigation system and in the Route determination are considered.

Also, the navigation system includes a control unit. about the operating unit can, for example, from a destination Address are selected. Further, by the driver preferred information display can be selected. So is For example, the display of map extracts or the representation of arrows, for example to a Turn in point, possible. Regulations pertaining to Navigation system can also be in a common unit be present with a single operating unit.

If the vehicle is of different drivers used, these are also various system settings of the audio and / or Navigation Systems prefer. As a consequence, that each user before driving his personal will carry out the preferred system settings. This Process is for a time-consuming, must on the other hand Setting the system parameters when the audio or Navigation system occur. In many cases, the Settings therefore performed with the engine running. This is However, for environmental reasons not desirable. Further occurs particularly in company cars to the problem that the Address books of the navigation system by all users are cost. A personal assignment of an address book to a user is not possible.

is known from JP-A-10088878 it is known to a driver based on the used to identify the vehicle key and a device in a Motor vehicle with stored values ​​for to operate the identified driver, for example, adjust volume of a radio.

This is where the present invention, it is to made object, an audio and / or navigation system with simplified operation, especially when using the So further develop vehicle by multiple users and that a higher safety is achieved in the driver detection.

The object is achieved by an audio and / or navigation system dissolved Claim 1.

The inventive development of an audio and / or Navigation system eliminates the regular, time-consuming, manual entry of system parameters before Drive by the user. This is in respect of vehicles regularly used by different people, a achieved significant gain in comfort. Each user of the This vehicle may need only once his desired system parameters on the setting members of the audio and / or make navigation system and this then in a Storage element save. The storage element can be both be a part of the audio and / or navigation system or be located externally. If the user has his preferred system parameters once a storage element stored, so set it back each, once by the means for identifying the user this has been identified. The identification of the User effected speech recognition. For this, the audio and / or navigation system needs a Speech recognition system interact. The driver speaks one or a few words to by the A speech recognition system to be identified. If the User is recognized by the speech recognition system, the information of its identity to the audio and / or Navigation system passed, so that the associated can be selected and set system parameters.

If, for example, a vehicle with a remote-controlled locking system, so is the car key via an infrared or radio link with a receiver inside the vehicle in conjunction. Between the receiver and the keys are exchanged data. Therefore, it is without Another possible that the data exchanged interpreted to enhance that even between different keys authentic driver can be distinguished. In a such a case, the audio and / or navigation system the receiver of the remote-controlled locking system in Communicate, so that the information on the encryption keys to the audio and / or Navigation system can be passed.

For example, in particular, have the vehicles Superclass seat storage, in which the adjustment of the Driver's seat for different users of the vehicle is stored. If now a specific seat setting selected the seat memory, so can this Information at the same time the driver-specific System parameters of the audio and / or navigation system be selected and adjusted. The system parameters of Audio and / or navigation system may in particular also in the seat memory be stored with.

An inventive method for setting user-related system parameters in an audio and / or Navigation system of a motor vehicle is characterized in that the user on the basis of Speech recognition is identified, depending on the identified user system parameters from a Memory element can be read and the audio and / or Navigation system with the read system parameters is set.

The invention will be explained below with reference Embodiments and the drawing explained. It show:<dl tsize="7"><dt>figure 1</dt><dd>a schematic representation of a Systems according to the invention, </dd><dt>figure 2</dt><dd>an inventive audio system with user identification by speech recognition,</dd><dt>figure 3</dt><dd>an inventive navigation system.</dd></dl>

According to Figure 1, the audio and / or navigation system 1 is connected to a Storage element 2 and means 3 for identifying the user interacts. In the storage element 2 are for different users A, B, C, ... stored the preferred system parameters. The means 3 for identification the user may be a speech recognition system, a Key recognition system, a Sitzverstellspeicher or other user-related Sensors act. If by the means 3, for example, recognized that the vehicle of the user B key was used, it is this information is transmitted to the audio and / or navigation system. By the audio and / or navigation system are then stored in the storage element 2 stored user-related system parameters for the user B accessed and adjusted. Manual adjustment of the preferred system parameters can be dispensed by the user.

In Figure 2 an inventive audio system 1 is illustrated, equipped with a Speech recognition system 4 interacts. The audio system 1 includes a microprocessor 5 which is connected to a control unit 6th The control unit 6 includes various setting elements 7 for setting special system parameters of the audio system. This may be, for example, by adjusting the volume of the transmitter, the sound, the Receiving traffic messages, playing a CD or tape and the like. By means of the setting 7 is the User's preferred system parameters and stores them by Operating the memory button 8 in the storage element 2, also with the Microcomputer 5 is connected, from. Then still has the assignment a user identification to the Data effected. To this end, the user speaks a few words from the microphone 9 of the speech recognition system 4 and added to an evaluation unit 10 of the speech recognition system be forwarded. 4 The speech recognition system 4 shares the registered speech patterns a user code and passes them on the microcomputer 5 of the audio system 1. By pressing the Memory key 8 allows the user code previously in storage element 2 stored user-specific system parameters are assigned. In memory element 2 thus a data pair consisting of user code and user-specific system parameters stored. The described Operation must be carried out only once by each user. The aforementioned speech recognition system is beyond the scope of this invention and therefore need not be explained in detail herein.

the user uses the vehicle again, he must first only by Talk one or a few words picked up by the microphone 9 be and evaluated by the evaluation unit 10, identify. Can he User by the speech recognition system a stored code are assigned, then this code by the speech recognition system 4 passed on to the microprocessor. 5 The microprocessor 5 begins dialing the to the user code in the memory element 2 stored user-specific System parameters and sets the audio system accordingly. For this purpose, the microcomputer 5, for example, corresponding signals to Actuators 11 for adjusting the volume, the balance or the sound. Microprocessor 5 user system parameters can also other components not shown in 12 of the audio system output are, for example, for setting a preferred radio station. The audio signal with the user-specific system settings is over an audio amplifier 13 is output to one or more speakers 14th

In Fig. 3 as a further embodiment of a navigation system with the for the invention essential components shown. About an operating unit 6, which is connected to a microprocessor 5, settings can of System parameters of the navigation system are made. For example the desired form of presentation of the information on the display unit be selected 15th Further, the destination can be entered or from a list of possible destinations, the displayed on the display unit 15 are to be selected. The operating unit 6 and the display unit 15 can also be designed as a combined operator control / display unit. The Navigation system further includes a reader 16, with which on a CD-ROM 20 or similar storage medium stored digitized map data can be read into the microprocessor. 5 Further, the microprocessor 5 to 17 non-illustrated components Positioning of the vehicle by dead reckoning and / or GPS navigation connected. After entering a destination is the Microprocessor 5 because of the 17 sites identified by the components present Location of the vehicle and the map data, the distance to Destination is calculated. About the display unit 15 are driving information output with respect to the route to the driver. The microprocessor 5 can be connected to an audio system, not shown, where the audio system transmits traffic information to the navigation system be taken into account when planning a route. To this extent, is. a known navigation system

According to the invention, the microprocessor 5 is connected to a memory element 2 connected, in the user-specific system settings, such as the desired Information representation or an address book with preferred destinations and an associated user code are stored. to assign the user-specific system information to a user of the vehicle the microprocessor in addition to a vehicle locking system 18 connected, which depends on the used vehicle key 19 a User code sends to the microprocessor. 5 On the basis of the received Codes from the memory element 2 is associated with this code read user-specific system parameters and set.

The storage of these user-specific system settings must in turn, are made by each user only once. The storage the system settings, as with the previously described Audio system occur, whereby the user mapping now of the Locking system transmitted code with the system settings is stored.

In particular, for reasons of cost, the means for identifying the User usually not exclusively with an audio and / or navigation system Collaborate. Just a voice recognition system is particularly substantially for reasons of driving authorization control in his vehicle available. However, this may for setting the user-specific System parameters of the audio and / or navigation system be shared. For the reasons mentioned, therefore, the interaction the audio and / or navigation system with a seat memory in any case in one of the vehicles is already present, particularly preferred.
