Abstract
A power-operated vehicle closure system includes a vehicle door equipped with a cinch assembly having a power actuator and a closure latch assembly having a latch mechanism and a latch cinch mechanism. Actuation of the power actuator in a first direction provides a power cinch operation to cause the latch cinch mechanism to cinch the latch mechanism. Actuation of the power actuator in a second direction provides a power ice breaking operation to cause the latch cinch mechanism to open the latch mechanism. The system includes a controller that receives signals indicating the positions of a ratchet and a pawl of the latch mechanism and controls the power actuator to operate the latch cinch mechanism in either the first or second direction.
