STEERING ANGLE SENSOR

摘要

A steering angle sensor assembly (10) for determining absolute angular position of a steering wheel of a motor vehicle and includes a multi-axis detector (24) having an active operating mode and a standby operating mode and being adapted to measure speed and direction of rotation of the steering wheel. The steering angle sensor assembly (10) further includes at least one second detector (26) arranged to form a quadrature encoder to detect movement and direction of the steering wheel when the multi-axis detector (24) is in the standby or powered down operating mode.
