POWER LOCKING DOOR HANDLE WITH CAPACITIVE SENSING
First Claim
1. An exterior handle assembly for a vehicle door, comprising:
- a base adapted to be surface mounted on the door;
a hand grip connected to the base and with an open field between the base and the hand grip to receive an operator'"'"'s hand;
a power lock motor in the base;
a printed circuit board in the base to provide system controls for the handle assembly, with the system controls normally being in a sleep mode when an operator is not at the vehicle;
a capacitive sensor in the base adapted to wake up the system controls when an operator'"'"'s hand enters the open field; and
the printed circuit board adapted to send an unlock signed to the power lock motor after recognizing a user fob.

Abstract
A power locking door handle with capacitive sensing is provided for heavy duty vehicles. The door handle includes a base surface mounted to the exterior of the vehicle door and a hand grip mounted or formed with the base. The handle may be a pull type or push button type. A power lock motor and printed circuit board with a capacitive sensor are sealed within the base. When an operator'"'"'s hand is inserted between the hand grip and the base, the capacitive sensor sends a signal via the PCB to the motor to unlock the door latch. A key lock cylinder on the base overrides the lock motor if power to the motor is disabled.
