Abstract

A device for determining the angular position of the steering wheel in a motor vehicle uses a steering angle sensor and an electronic evaluation device for determining the angular position. The steering angle sensor is integrated in a contact unit for transmitting energy and data from stationary subassemblies of the vehicle to the steering wheel and vice versa. Preferably, the steering angle sensor is disposed as part of a stator and rotor in a contact unit which operates in a contactless manner and comprises the stator and the rotor. In this way, the steering angle sensor does not require any additional space for installation and costs are reduced.
