Abstract: 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.

Abstract: A drive authorization system for an electric drive includes a predefined number of field coils and a rotationally movable element. An evaluation and control unit for operation of the electric drive determines the current position of the movable element from several items of positional information, which can be made available by a predefined number of angle of rotation sensors. To implement an electronic immobilization function, positions, the number of the active rotation angle sensors, or both those positions and that number are made encodable. The evaluation and control unit decodes the encoded positional information of the active rotation angle sensors in order to determine the current position of the movable element. Operation of the electric drive is possible only after successful decoding of the positional information.

Abstract: A driving authorization system comprises an electronic immobilizer function which is coupled to a rotary shaft sensor. The rotary shaft sensor senses the position and/or rotational speed of the rotary shaft by means of a pickup wheel arranged on a rotary shaft, and transmits that information to a vehicle control unit which enables the electronic immobilizer function. According to the invention, the pickup wheel comprises a predefined number of teeth which are arranged distributed along the circumference of the pickup wheel according to a code, and an encoded rotational speed signal which is picked up by the rotary shaft sensor and can be decoded by the vehicle control unit. The vehicle control unit enables the immobilizer function only after successful decoding of the encoded rotational speed signal. A synchronization time for detecting a specific position of the rotary shaft is part of the encoded rotational speed signal.
