Problems solved by technology

During the reset operation, the reverse operation of the power release motor is known to generate noise, which is considered undesirable
Another issue with "power" resetting of the power release mechanism is the potential inability to subsequently release the latch mechanism
This potential situation is especially problematic in closure latches that are not equipped with a mechanical internal latch release mechanism since the vehicle occupant may not be able to release the latch mechanism and escape from the vehicle

Abstract

The present disclosure relates to a closure latch for a vehicle door, and more particularly to a closure latch for a vehicle door equipped with a passive entry feature. To this end, the present disclosure relates to the use of a bidirectional power release mechanism operable in a first mode to release a latch mechanism under normal operating conditions and which is operable in a second mode to release the latch mechanism under emergency operating conditions.

Description

[0001] Cross References to Related Applications [0002] This application claims U.S. Provisional Patent Application No. 62 / 510,922, the entire disclosure of which is hereby incorporated by reference. technical field [0003] The present disclosure generally relates to closure latches for vehicle passenger doors. More specifically, the present disclosure relates to closure latches equipped with bi-directional power release mechanisms. Background technique [0004] This section provides background information related to closure latches and is not necessarily prior art to the closure latches of the present disclosure. [0005] Passive entry systems for vehicles are provided on some vehicles to allow a vehicle user with a key fob to simply pull the door handle and open the door without inserting a key into a keyhole located in the door. The key fob is typically equipped with electronics that communicate with the vehicle's on-board control system to authenticate the user. W...
