E-LATCH WITH MICROCONTROLLER ONBOARD LATCH AND INTEGRATED BACKUP ENERGY

摘要

A latching assembly is used on a door of a motor vehicle, wherein the motor
vehicle includes a main electric supply and a striker. The latching assembly
includes a ratchet that is selectively rotatable with respect to the striker
to latch and unlatch the door. The latching assembly includes a pawl that is
selectively engagable with the ratchet to selectively prevent the ratchet from
rotating. The latching assembly includes a motor which is electrically
connected to the main electric power supply. The motor is operatively
connected to the pawl for pivoting the pawl into and out of engagement with
the ratchet. The latching assembly also includes a backup battery disposed
adjacent the motor for supplying electric power when the motor is disconnected
from the main electric supply.
