Definitions
- the invention relates to a safety device according to the preamble of patent claim 1.
- DE-OS 36 27 194 results in a portable high-frequency transmitter for keyless access systems, which is itself designed as a chip card.
- the interaction between transmitter and receiver can be designed in different ways. For example, it is possible to provide the transmitter itself with an actuating element by which the transmitter is caused to emit the code signal.
- security devices of the type mentioned at the outset are known in which the receiver causes the transmitter to emit the code signal.
- DE-OS 35 36 377 in which the receiver in turn sends a question signal to the portable transmitter when a door flap or the like is actuated.
- a memory device within the motor vehicle, which controls user-specific settings of operating and use elements of the motor vehicle. This includes setting the driver's seat, for example in terms of its axial position, the inclination of the backrest and the height of the headrest. This also includes settings for the rearview mirror, the steering wheel, the pedals and also the heating and air conditioning system, the maximum permissible speed and other comfort features such as the shock absorber. With the help of the memory device, the appropriate setting of these elements is carried out automatically for the respective vehicle user. The memory device in turn is controlled by the user. For example, it can have different push-button switches that enable the above-mentioned elements to be set in three different ways for vehicle users 1, 2 and 3.
- a memory device offers a considerable gain in comfort, it has the disadvantage that it is usually left to the vehicle user himself to make the "right" selection. It can often happen that an incorrect selection is not recognized or is recognized only too late, with the result that the actual advantage of a memory device is reversed.
- the invention is based on the object of providing a security device of the type mentioned at the outset which, with maximum convenience, enables both the control of the anti-theft devices and further elements which can be set individually for the user.
- the invention solves this problem by the characterizing features of claim 1.
- the code signal consists of two parts. One part is the same for every user and is used to legitimize the vehicle determine user for the respective motor vehicle. If the vehicle user sends out the correct code signal with regard to this part, the anti-theft devices are set to the desired state. This can be, for example, a central locking and unlocking system and an ignition lock system.
- the further portion of the code signal is individually assigned to the respective vehicle user and, via a corresponding evaluation device which is connected downstream of the receiver, initiates the user-specific setting of the elements mentioned.
- This is associated with a significant improvement in comfort, since it is no longer necessary for the vehicle user to control the theft protection devices and the user-individually adjustable devices independently of one another and, as a rule, by means of two separate operating processes. Rather, as part of the verification of the vehicle user with regard to his authorization, if the result of this verification is positive, the individual setting of the elements mentioned is also carried out at the same time. This can be done automatically for the control of the theft protection devices without separate control of the transmitter in the manner known from DE-OS 35 36 377 when the vehicle user tries to open the motor vehicle with the help of the door flap.
- the safety device according to the invention does not have a limitation of the various adjustment options, such as is given, for example, in the case of a memory device with three push-button switches. This is irrespective of how the additional portion of the code signal is designed. It can only be a coding for the respective vehicle user act. With the help of a provided in the motor vehicle
- the memory device is then made for this coding, the respective setting of the elements mentioned.
- the additional portion can also be a coding of the different ones
- Part of the code signal is thus composed of different parts, each of which is assigned to one of the elements and which determine its setting.
- a memory device in the motor vehicle can thus be dispensed with. It is then only necessary to specify the requirements contained in the additional part for the
- the mode of operation of the security device according to the invention is also independent of the manner in which the additional portion of the code signal is transmitted. It can be both an additional portion that is sent out immediately after the first portion that is characteristic of the identification of the vehicle user. In this case, the transmitter generates a uniform code signal. Alternatively, the additional portion can also be sent with a time delay. This can take place, for example, in the form of a question / answer dialog, in which the first part is first sent out by the transmitter and, if reception is successful, the second part is sent out by the transmitter on the basis of an acknowledgment signal sent by the receiver.
- the transmitter can be a device which is a user-specific identifier, for example in the form of an inscription or a distinctive design of the transmitter housing.
- a separate mechanical part to the additional portion of the code signal, which part is part of the transmitter and can be removed from it.
- the user-specific generation of the transmitter only the addition of the respective mechanical part is required.
- 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 in accordance with 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 or settlement.
- they can also be used to make the individual settings of the motor vehicle elements mentioned 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 received completely in an opening in the transmitter body, it is thus largely protected against damage and changes to its contents by means 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 described in DE-OS 36 27 194 for the interaction between the transmitter designed as a chip card and the vehicle's own 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.
- An extension of the invention aims to
- (Portable) transmitters 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 invention is further illustrated by the drawing. It shows:
- FIG. 1 shows the basic mechanical structure of a portable transmitter which is used in the context of the safety device according to the invention
- Fig. 2 shows schematically the operation of the safety device according to the invention and Fig. 3 schematically shows an expansion stage of the safety device according to the invention.
- 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 design can be found in detail, for example, from DE-OS 36 27 194.
- the housing 1 also serves to hold a chip card 2, which can be inserted into the housing 1 via an opening 3 and is completely contained in the housing 1 in the inserted state.
- 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 are, for example, the 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 derived from the storage content of the electronic memory of the chip card 2 is formed. It serves to set the above-mentioned operating and usage elements of the motor vehicle in a user-specific manner.
- the two-part code signal emitted by the transmitter arrives via an antenna of the motor vehicle in an evaluation unit 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 4 is prompted 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. If the first part, which is responsible for the theft protection devices, matches the expected code signal, the evaluation unit 4 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.
