Embodiment approach

[0041] According to an exemplary embodiment of the present invention as described herein, the power source includes a rechargeable power source, and the access system further includes a power management controller for monitoring the status of the rechargeable power source and using For controlling recharging of the rechargeable power source via at least one on-board power source of the vehicle, the power management controller is disposed in one of the at least one door or the release handle and is controlled by the powered by the rechargeable power source described above. However, it should be appreciated that with the benefit of this disclosure, the power supply may be a single charge power supply rather than rechargeable, which can be replaced once depleted.

[0042] As used herein, the term "electric latch" means an essential component of a vehicle's electric door latch system that is electrically, mechanically, and / or electromechanically "downstream" of a door's release ha...

Abstract

A system for accessing a vehicle when the main battery is incapable of supplying sufficient power for actuating the vehicle's power door locks/latches comprises: a power supply in the door or release handle supplying power to the vehicle's power latch; an entry authentication device for receiving one or more inputs for authenticating a user's access to the vehicle, the entry authentication device powered by the rechargeable power supply; and a latch controller powered by the power supply and operatively connected to the power latch and the at least one entry authentication device to receive information from the entry authentication device corresponding to the one or more inputs. The latch controller can authenticate a user's access to the vehicle to place the power latch in an unlocked state so that the door can be opened.

Description

[0001] Cross References to Related Applications [0002] This application is related to and claims the benefit of priority to US Provisional Patent Application Serial No. 61 / 583,343, filed January 5, 2012, the disclosure of which is incorporated herein by reference in its entirety. technical field [0003] The present disclosure relates generally to access systems for vehicles having doors with power latches, and more particularly, to Systems and devices for actuating electric latches when not in operation. Background technique [0004] Conventionally, vehicle doors include a door latch mechanism received between inner and outer panels of the door. When the door is closed, the latch mechanism cooperates with elements provided on the door frame to latch the door, and the latch mechanism cooperates with a user-actuated release handle to unlock the door so that the door can be opened manually. [0005] Historically, vehicle latch mechanisms have been entirely mechanical, with...
