1. A system for opening or closing a closure member of a vehicle comprising:
an actuator assembly comprising an electric motor operably coupled to an extensible member coupled to one of a body or the closure member for opening or closing the closure member;
an accelerometer configured to sense one of movement and orientation of the closure member and output an accelerometer signal corresponding to the one of movement and orientation of the closure member sensed, wherein the electric motor is controlled using an adjusted accelerometer signal; and
a controller coupled to the electric motor and to the accelerometer, wherein the controller is adapted to receive the accelerometer signal, generate the adjusted accelerometer signal, and control the electric motor based on the adjusted accelerometer signal, wherein the controller is further configured to determine the 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.
