Strut position sensor including a magnet mounted on an idler gear contained in a stator portion, which is movable relative to a rotor portion connected to the strut, and a galvanomagnetic sensor in the stator portion for detecting angular position of the strut

摘要

A power actuator system for a movable vehicle panel such as a lift gate assembly includes a position sensor that detects the pivotal movement of a strut mechanism of the power lift gate assembly relative to the host vehicle. A rotary sensor is coupled directly to an end component of the strut mechanism and provides signals that indicate the total amount of pivotal or rotary movement of the strut mechanism and the lift gate during the opening and closing of the lift gate. The signals provide information to determine the absolute position of the strut and the lift gate for processing in the vehicle's electronic control unit.
