Definitions

  • the invention relates to a safety device according to the preamble of patent claim 1.
  • Such a safety device is known from US-A-4451887.
  • the other part of the code signal which controls the user-individually adjustable devices, enables these devices to be adapted to the respective user. This results in a considerable gain in comfort if, for example when the motor vehicle is started up, the authorized user is able to use the motor vehicle at the same time and the user-adjustable parts are set for the respective vehicle user.
  • a "wrong" setting of the user-individually adjustable devices can occur, namely when the user uses the transmitter of another authorized user.
  • the invention has for its object to provide a safety device of the type mentioned, which is easy to use and with the help of which the control of the user-individually adjustable devices is initiated in the correct manner.
  • the transmitter is composed of two parts. In addition to a basic module with which the anti-theft devices are controlled, it contains the separate mechanical part with which the user-individually adjustable devices are controlled. The transmitter can thus be completed individually by adding this separate mechanical part.
  • the mechanical part in turn can be designed in different ways. For example, it can have a magnetic coding that is generated by the vehicle user himself by adjusting magnet bodies that can be changed in position. In contrast, there is a significant improvement if the removable part contains an electronic memory which is occupied according to the additional portion of the code signal. In this way it becomes possible to design the additional portion of the code signal so that it consists of individual parts, each of which enables the setting of a motor vehicle operating or use element. In addition, such a memory is mechanically insensitive and thus eliminates the risk of incorrect settings of the elements mentioned.
  • Chip cards are becoming increasingly important and are used as a means of payment and settlement.
  • they can also be used to make the individual motor vehicle element settings for the respective vehicle user. Since the vehicle user always only has his personal chip card at hand, there is a risk of one possible incorrect setting of the elements mentioned as a result of an incorrect chip card excluded.
  • a further embodiment of the invention deals with the simplification of the mechanical structure provided that a chip card is used. If this is completely received in an opening of the transmitter body, it is thus largely protected against damage and changes to its memory content with the help of external magnetic fields.
  • the transmitter housing it is only necessary to read out the content of the electronic memory. This can be done in the manner as described in DE-A-36 27 194 for the interaction between the transmitter designed as a chip card and the motor vehicle receiver. It is then only necessary within the scope of the invention to provide a receiver within the transmitter housing itself which, for example, causes the memory content of the chip card to be read out in response to a corresponding transmission signal. This memory content is converted into the corresponding portion of the code signal within the transmitter housing and transmitted to the motor vehicle by the transmitter.
  • the (portable) transmitter is additionally provided with a receiver and a memory for a code signal with vehicle and / or user-specific data content.
  • This code signal is transmitted by the motor vehicle immediately before or after the code signal transmitted by the transmitter and stored in the receiver. It makes sense that to store vehicle-specific data in conjunction with that for the portion of the code signal that controls the state of the anti-theft devices. Accordingly, the vehicle user-specific data must be recorded in connection with the other part of the code signal. If a memory is provided in a separate mechanical part for the latter, the vehicle user-specific data can thus also be processed independently of the vehicle-specific data. This is possible, for example, in a workshop or in a customer service acceptance point.
  • the transmitter 1 'shown in FIG. 1 for a wirelessly transmissible code signal is seated in a housing 1 which has the electronic elements required for transmitting and receiving a code signal and for generating or converting these signals (not shown).
  • the construction can be found in detail, for example, from DE-A-36 27 194.
  • the housing 1 also serves to receive a chip card 2, which can be inserted into the housing 1 via an opening 3 and is completely contained in the housing 1 when inserted.
  • the chip card 2 contains an electronic memory (PROM, not shown) in which data for setting operating and use elements of the motor vehicle are contained. These elements include central locking, the height and length adjustment of the steering column and the heating and air conditioning system.
  • a receiver via which an external code signal can be received and processed on the one hand and via which the content of the electronic memory of the chip card 2 is also read out.
  • a transmitter is included within the housing 1, which generates a code signal composed of two parts and wireless, z. B. emits as an infrared or radio frequency signal.
  • One of the two parts is formed according to a predetermined algorithm and represents the user identification with the aid of which the anti-theft device of the motor vehicle is unlocked.
  • the other part is characteristic of the respective vehicle user and is made up of the memory content of the electronic memory of the chip card 2 is formed. It is used to set the named operating and usage elements of the motor vehicle in a user-specific manner.
  • the two-part code signal emitted by the transmitter passes through an antenna of the motor vehicle into an evaluation unit 4a which contains a transmitter and a receiver.
  • the antenna in turn can sit in the driver's door, the passenger door and / or the tailgate of the motor vehicle.
  • a switch contact which is a door handle contact 4 or 5 and a tailgate lock button 6. If this contact is actuated, the evaluation unit 4a is caused to send out a question code via the antennas 1 to 3.
  • the portable transmitter 1 'receives this question code and is thereby caused to transmit its two-part code.
  • the evaluation unit 4 a initiates the unlocking of the theft protection devices. This causes the driver's door, all other doors, the tailgate and also the ignition and steering wheel lock to be locked.
  • the transmitter 1 can trigger additional functions. This is done using buttons 7 to 10, when pressed, the change in the state of the anti-theft device from a greater distance (button 7), the remote control of devices outside the motor vehicle such as a garage door (key 8) and the remote control of other devices of the motor vehicle, such as the window regulator (key 9) and the exterior lighting system (key 10).
  • the extension of the safety device shown in FIG. 3 schematically shows the structure of an overall system with mutual transmission and reception options between the transmitter 1 ', a motor vehicle 11 and other external devices.
  • the latter is, for example, a read / write device 12 in a workshop or the like.
  • the transmitter 1 ' consists of a part 1, which serves to determine the portion of the transmitted code signal required for the user identification.
  • part 1 now also contains a receiving part, which is shown as a combined transmitting / receiving part (S / E part).
  • S / E part a combined transmitting / receiving part
  • NV non-volatile
  • the transmitter 1 ' also contains the chip card 2, which is also provided with a transmitting / receiving part, a non-volatile memory and a controller. Parts 1 and 2 exchange data with each other. A bidirectional data exchange is possible between the transmitter 1 'and the motor vehicle 11.
  • the data of the data contained in the non-volatile memory of parts 1 and 2 are transmitted to the motor vehicle and, conversely, the data contained in these memories are queried or updated by the motor vehicle.
  • the division of the data is expediently carried out in such a way that the user-specific data are stored in the chip card 2. This data can in turn be entered or updated externally by the read / write device 12.
