Abstract
A system for opening or closing a closure member of a vehicle and an accelerometer calibration method are provided. The system includes an actuator assembly with an electric motor operably coupled to an extensible member for opening or closing the closure member. The system also includes an accelerometer configured to sense movement of the closure member and output an accelerometer signal. An actuator controller is coupled to electric motor and to the accelerometer and is configured to determine an adjusted accelerometer signal as the accelerometer signal adjusted using one of a plurality of predetermined compensation factors determined through an accelerometer calibration process temporally before installation of the accelerometer in the vehicle. The actuator controller then controls the opening or closing of the closure member using the electric motor based on the movement of the closure member as represented by the adjusted accelerometer signal.
