Motor vehicle steering system has servomotor to regulate wheel lock angle and sensor to monitor its shaft rotation

摘要

The steering system incorporates a servomotor (2) that creates an effort to regulate the wheel lock angle of one of the vehicle's steerable wheels (3). The rotation of the servomotor shaft (4) is picked up by the position detector of a rotor (5) whose signals are used by an evaluation unit (6) to determine the wheel's absolute angle of lock.
