Abstract

The invention relates to a closing system for motor vehicles involving access authorization and driving authorization by means of a control unit provided with means of communication. Said communication means comprise a stationary transmitter-receiver unit in the vehicle and a mobile transmitter-receiver unit in a wireless hand telephone (10). The control unit monitors the data transferred during said communication for access or driving authorization and activates or deactivates the corresponding systems if authorization is valid. The hand telephone (10) contains an SIM card (15) for telephonic network operation. In order to use the closing system in a quick and comfortable manner, the SIM card (15) is also a carrier for the access and driving authorization data. (16). A bi-directional local communication hands-free system operating in the GHz range is also used in the motor vehicle. Said telephonic local communication is also used for transmitting access and/or driving authorization data (16).

Claims

1. Locking system for motor vehicles (20) with an access authorization system for the releasing and locking of doors (24), hatches (28, 27), or the like in the vehicle (20), with a driving authorization system for starting, operating, and stopping an engine in the vehicle (20) and possibly for enabling and disabling a steering wheel (18) of the vehicle (20), and with a control unit (33) for both systems, which is operated by communication devices, such that the communication devices consist of a stationary transmitter-receiver unit (25, 25′

) in the vehicle (20) and of a mobile transmitter-receiver unit in a wireless hand telephone (mobile phone 10), and the control unit (33) checks the transmitted data for its access and driving authorization and, if successful, activates or deactivates the associated system, such that, for its telephonic network operation, the mobile phone (10) contains a SIM card (15), which can be inserted in and, if necessary, removed from its housing, characterized by the fact that the SIM card (15) simultaneously serves as the carrier for the access authorization data and/or the driving authorization data of the communication (16), that a hands-free system for bidirectional local communication (30) of the mobile phone (10), which operates in the GHz range, is installed in the vehicle (20), that the local communication (30, 30′

) intended for telephone traffic simultaneously carries out the transmission of the access and/or driving authorization data (16) between the mobile phone (10) and the control unit (33) in the vehicle (20), and that the communication devices (25, 25′

) provided in and on the vehicle (20) distinguish a vehicle interior position and exterior position of the mobile phone (10).

2. Locking system in accordance with claim 1, characterized by the fact that the stationary transmitter-receiver (25, 25′

) devices for the local communication (30, 30′

) are located in both the vehicle interior (22) and in the exterior space (32) outside the vehicle (20).

3. Locking system in accordance with claim 2, characterized by the fact that the transmitter-receiver devices (25′

) located in the exterior space (32) outside the vehicle (20) are integrated in the door handle (23).

4. Locking system in accordance with any of claims 1 to 3, characterized by the fact that there is a cradle for the mobile phone (10) in the vehicle interior (22), and that the transmitter-receiver devices (25) for the local communication (30) are located near the cradle.

5. Locking system for motor vehicles (20)

with an access authorization system for releasing and locking of doors (24), hatches (28, 27), or the like in the vehicle (20),

with a driving authorization system for starting, operating, and stopping an engine in the vehicle (20) and possibly for enabling and disabling a steering wheel (18) of the vehicle (20),

and with a control unit (33) for both systems, which is operated by communication devices,

wherein the communication devices consist of a stationary transmitter-receiver unit (25, 25′

) in the vehicle (20) and of a mobile transmitter-receiver unit in a wireless hand telephone (mobile phone 10),

and the control unit (33) checks the transmitted data and, if successful, activates or deactivates the associated system,

with a SIM-card, for the telephonic network operation of the mobile phone (10), which can be inserted in and, if necessary, removed from its housing,

wherein the SIM card (15) simultaneously serves as the carrier for the access authorization data of the communication (16),

and with a hands-free system in the vehicle (20) for a bi-directional local communication (bluetooth system 30) of the mobile phone (10) which operates in the GHz range, comprising

in addition to external communication devices (25′

) at the vehicle, which respond to a vehicle exterior position of the mobile phone (10),

internal communication devices (25) arranged in the vehicle interior (22) which recognize the vehicle interior position of the mobile phone (10),

wherein, in addition to the access authorization data, vehicle-specific driving authorization data (16) for rendering operative the engine electronics, for starting and for operating the engine, are arranged on the SIM-card (15),

and wherein the driving authorization data (16) of the SIM-card (15) are received and evaluated by the network communication (bluetooth-system 30) of the mobile phone (10) which operates in the GHz range.

6. The locking system according to claim 5, wherein the transmitter-receiver devices (25′

) acting in the exterior area (32) of the vehicle (20) are integrated in the door handle (23) and/or in the actuating device (29) of the rear flap (28).

7. The locking system according to claim 5, wherein a cradle for the mobile phone (10) is located in the vehicle interior (22)

and wherein the inner transmitter-receiver devices (25) for the local communication (bluetooth-system 30) is arranged in the area of the cradle.
