POWER RELEASE ACTUATOR

摘要

A method as disclosed for operating a motor bidirectionally to cinch an d release a closure panel of a motor vehicle. The motor is operatively connect ed to a pawl, ratchet and spring of a latch for the closure panel. The method includ es the step of driving the motor in a cinching direction to rotate the ratchet to cinch the closure panel in the closed position. The motor is then returned to a park position by driving the motor in a park direction opposite to the cinching direction. Power is applied to the motor to drive the motor in a release direction to drive the motor past the park position with respect to the cinching direction. In doing so, the motor contracts the spring as it moves in the release direction. Power is then removed from the motor allowing the spring to force the motor to return to the park position as the spring returns to its steady state position.
