Abstract:
1. A method of controlling a door handle to move into an extended position from a vehicle door, comprising: running a motor operatively coupled to a door handle to facilitate the door handle retracting into the vehicle door, the retraction being performed solely by a biasing member that urges a swing arm coupled to the door handle to retract; receiving a first retraction force signal response corresponding to a first retraction force applied to a retraction force sensor as the swing arm retracted by the biasing member also retracts into the vehicle door and presses against the retraction force sensor; instructing the motor operatively coupled to the door handle to stop running when the first retraction force signal indicates the first retraction force is greater than a retraction stop threshold; receiving a second retraction force signal response corresponding to a second retraction force applied to the retraction force sensor as a result of an inward push on the door handle and the swing arm coupled to the door handle pressing against the retraction force sensor; and instructing the motor operatively coupled to the door handle to facilitate extending the door handle from the retracted position into an extended position from the vehicle door in response to receiving the second retraction force signal response, the extension occurring against the biasing member and being performed solely by running the motor.
