ABSTRACT:
A vehicle passive entry side door latch release system engageable with a release cable connected a door latch includes a moveable linkage assembly engageable with the cable, and a motor including an output shaft engaged with a tensioning gear for driving a ratcheting gearwheel rotatably affixed to a coil spring, with the gearwheel including external teeth engageable with a rack affixed to the linkage to move the cable to unlatch the door latch. A pivotable ratcheting pawl may be engageable with the gearwheel to allow or prevent rotation of the gearwheel. Operation of the motor may drive the gear to drive the gearwheel in a rotary direction to energize the spring, and disengagement of the pawl from the gearwheel may allow stored energy in the spring to drive the gearwheel in an opposite rotary direction to thereby drive the rack to move the cable to unlatch the door latch.
