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).
