STEERING ANGLE SYSTEM AND METHOD FOR MEASURING A STEERING ANGLE

摘要

The invention relates to a steering angle sensor system (1) for measuring the steering angle in a motor vehicle, said system comprising a magnetic encoder (85) which is magnetically coupled to at least one magnetic field sensor (2) detecting a variation in the steering angle even when the ignition is turned off, and an electronic memory (10) for storing steering angle information. The steering angle sensor system (1) also comprises at least one other element (4) sensitive to magnetic fields in addition to the sensor element(s) for detecting the steering angle, said element being magnetically coupled to the magnetic encoder and prematurely identifying steering movements for at least partial initiation of the steering angle sensor system (1) and/or another system.
