Steering angle sensor system and method for measuring a steering angle

摘要

A steering angle sensor system for measuring a steering angle in a motor vehicle. The steering angle sensor system includes a magnetic encoder which is coupled to at least one magnetic field sensor that senses a variation in the steering angle even when the ignition is switched off, and an electronic memory for storing the steering angle variation. The steering angle sensor system also includes at least one magnetic-field-sensitive element which is coupled to the magnetic encoder for detecting the occurrence of steering movements at an early time in order to at least partially activate the steering angle sensor system and/or another system.
