Vehicle steering angle determination sensor comprises a synchronous rotor and coupled rotating body each with magnetic tracks and magnetic field sensing arrangements

摘要

The steering angle sensor (2) rotor (4) that rotates synchronously with the steering wheel and is coupled to the steering wheel or column via a coupled rotating body (8). Both rotor and rotating body have magnetic sections (24, 29) with different polarity sectors (26, 28, 29a, 29b) and magnetic field sampling arrangements (12, 18), whose output signals are fed to the evaluation unit. The invention also relates to a corresponding method for determining the absolute steering angle of a steering wheel.
