Abstract: The opening of vehicle doors often leads to collisions with stationary obstacles that are not visible to the occupants or with moving obstacles that approach the vehicle without being noticed. Thus to avoid collisions when vehicle doors are opened, the aim of the invention is to take any modifications to the environmental situation of the vehicle as a result of a movement of the vehicle and the detected objects into consideration. This allows a collision of the vehicle doors with the objects to be reliably avoided. To achieve this, in a first step the probable trajectory of a vehicle is determined. In an additional step, the objects in the vicinity of the vehicle are detected and probable trajectories of said detected objects are determined. Respective probability ranges are then defined both for the vehicle and the pivoting zone of the vehicle doors and for the detected objects.

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.
