Steering angle sensor for motor vehicle

摘要

The sensor has a steering angle sensor element (3) with which the angular position of a steering wheel is detected wrt. a full rotation. A counting unit (4) counts the number of steering wheel null transitions. An initialising arrangement (6) contains a comparator which sets an actual steering wheel signal from a sensor in relation to a reference value. A setting device initialises the counter if the compared signals coincide. The initialising arrangement contains a detector which derives the running position of the drive wheels, which are affected by the steering wheel, from representative dynamic parameters detected by the sensor elements. A corresp. signal is used to form the comparator's reference value.
