A system for controlling an access authorization and/or driving authorization for a vehicle includes at least one mobile communication device and a control unit in the vehicle that receives and checks authorization data sent from the mobile communication device. The mobile communication device has a data carrier for storing the authorization data. The data carrier has at least one protected storage region for the storage of the authorization data. A database server transfers encrypted authorization data to the data carrier for storage in the protected storage region.

Device and method for controlling an access authorisation and/or driving authorisation for a vehicle

A device for prompting a controller in a vehicle to switch the controller from a normal operating state into an idle state includes a prompting device which switches a power supply through to the controller when activated to bring it into the normal operating state. The prompting device is connected in series to a first condenser and a resistor between power supply lines. A central tap between the first condenser and the resistor is connected directly or indirectly with the control input of a first transistor. An output of the first transistor is connected directly or indirectly with a control input of a second transistor that switches the supply current for the controller to be prompted. A connection line led back from the second transistor to the node between central tap and control input of the first transistor.

Device for prompting a controller

An electronic vehicle key has a radio receiver for receiving radio call information which is transmitted by a control center, and a key communication device for communicating with a vehicle communication device in an associated vehicle, signals transmitted by the key communication device to the vehicle communication device serving to activate or deactivate an immobilizer on the vehicle. According to the invention, a key controller, which administers a mobility account, is provided in the electronic vehicle key; and radio call information is transmitted by a control center is registered as a &ldquo;credit&rdquo; in the mobility account. Relevant events are processed as &ldquo;debits&rdquo; in the mobility account, and deactivation or activation of the immobilizer on the vehicle is dependent on the account value of the mobility account.

Electronic vehicle key

A vehicle key with an installed electronic system is used, for example, for wireless communication with the vehicle for controlling a vehicle locking system or a drive-away blocking system. The electronic vehicle key has a voice memory, a voice output unit, a control unit with a voice system function a radio call receiving device, a radio call information output unit and a control unit. By means of the voice system function, for example, the parking site of a vehicle can be stored in the key and can be emitted again in voice form. A key equipped with the radio call receiving function permits the transmission of radio call messages to the owner of the key.

An adjusting device having a multi-function operating switch is provided. The function elements which can be controlled by the operating switch can be selected in a variable manner on the user side from a totality of function elements. In a motor vehicle, the operating switch may, for example, have the configuration of a tunnel driving switch by which function elements that can be selected by the user, such as window lifting mechanisms, low-beam and interior-light units, etc. can be controlled into function positions which can also be predetermined by the user for driving through tunnels. This implements a high operating comfort for the individual and situation-adapted adjustment of a condition which can be influenced by a totality of function elements.
