DOOR HANDLE SYSTEM FOR A VEHICLE DOOR

摘要

A door handle system for a vehicle door has a door handle and at least one flap for reversibly closing a grip recess set back to the rear of the door handle. An actuating device pivots the one or more flaps between a closed position that covers the handle recess and an open position that exposes the handle recess. A distance sensor is disposed on the flap. A control and evaluation unit uses a first measurement signal that is output by the distance sensor in the closed position, to deduce that a vehicle user is approaching so as to activate the actuation device to move the one or each flap into the open position. A second measurement signal that is output by the distance sensor in the open position indicates that the door handle is grasped by the vehicle user.

主权项

1. A door handle system for a vehicle door, the door handle system comprising:
a door handle having a rear side; at least one flap for reversibly closing off a grip recess formed in the vehicle door and set back with respect to an outer surface of the vehicle door relative to the rear side of said door handle; an adjusting device configured to pivot said at least one flap between a closed position that covers said grip recess and an opened position that reveals said grip recess; a distance sensor at least in part disposed on said at least one flap or on one of a plurality of said flaps; and a control and evaluating unit configured:
with reference to a first measuring signal output by said distance sensor in the closed position, to conclude that a vehicle user is approaching said at least one flap;to control said adjusting device so as to adjust said at least one flap into the opened position when detecting that the vehicle user is approaching said at least one flap; andto determine with reference to a second measuring signal output by said distance sensor in the opened position whether said door handle is being gripped by the vehicle user.
