1. A servo actuation system (20, 520, 620, 720, 820, 920, 1020, 1120) for a closure member (12) of a vehicle (10) comprising:
an actuator assembly (622) having an actuator housing (141, 148, 184, 188, 206, 408, 422, 684);
the actuator assembly including an electric motor (36) disposed in the actuator housing and configured to rotate a driven shaft (166) operably coupled to an extensible member (134) coupled to one of a body (14) or the closure member for opening or closing the closure member; and
an accelerometer (697) configured to sense movement of the closure member by a user manually moving the closure member while the electric motor (36) is moving the closure member (12);
at least one servo controller (50, 850, 1050) coupled to the electric motor (36) and to the accelerometer (697) and configured to determine whether to open or close the closure member (12) using the sensed movement of the closure member (12) by the user, and control the electric motor (36) to move the closure member (12) based on the sensed movement and an inclination of the closure member (12) sensed using the accelerometer (697).
