ABSTRACT:
A powered vehicle door closing system for producing an auto-closing action to automatically move a latch member from a half-latched position to a fully-latched position comprises a reversible motor mechanically linked through a linkage to the latch member, for powering a final, low-displacement/high-force movement of a vehicle door, and a controller for controlling the motor. The controller includes a full-latch confirmation section for confirming that the latch member is maintained at its fully-latched position, and a motor-drive limiting section for limiting re-activation of the motor so as to avoid ineffective auto-closing action of the system when the full-latch confirmation section decides that the latch member has already been shifted to and maintained at the fully-latched position.
