Abstract
A vehicle door handle system includes a pair of electrodes disposed within an operating handle located on the outer surface side of a door along the longitudinal direction of the vehicle. A detection circuit for detecting a change in capacitance between the two electrodes is connected to the two electrodes.
Claims17
A vehicle door handle system comprising:
- an operating handle disposed on an outer side surface of a vehicle door along a longitudinal direction of the vehicle;
- a pair of electrodes disposed, in their entirety, within the operating handle;
- and
- a detection circuit that detects a change in capacitance between the two electrodes, the detection circuit being connected to the two electrodes.
