Abstract
A vehicle door handle includes a coupling device having a handle lever movable between a flush position in which the handle lever is flush with an exterior door panel surface, a ready position in which the handle lever is extended and graspable by a user, and an inwards pushed position. The handle lever includes a handle lever shaft rotatively connected to a handle lever base. The vehicle door handle further includes a positioning device, at least one reduction mechanism driven in rotation by an electric motor and driving in rotation the handle lever shaft, and an electronic control unit operable to create a motor short circuit so as to generate a torque resistance on the handle lever.
Claims11
A vehicle door handle comprising:
- a coupling device having a handle lever movable between:
- a flush position in which the handle lever is flush with an exterior door panel surface,
- a ready position in which the handle lever is extended and graspable by a user so as to open the exterior door panel surface, and
- an inwards pushed position in which the handle lever is retracted at a rotation angle, the handle lever comprising a handle lever shaft rotatively connected to a handle lever base about the rotation angle;
- a positioning device adapted to detect the rotation angle of the handle lever shaft;
- at least one reduction mechanism, driven in rotation by an electric motor and driving in rotation the handle lever shaft;
- and
- a control unit operable to receive inputs from the positioning device and to send a signal to the electric motor,
- wherein the control unit is operable to create a motor short circuit so as to generate a torque resistance on the handle lever once an inwards pushed predetermined angle of rotation a of the handle lever shaft is reached.
