Abstract: An accelerator pedal unit (1) for a motor vehicle includes an accelerator pedal (11) for controlling a propelling force of a motor of the motor vehicle, and a return spring. A position change of the accelerator pedal (11) from its starting position caused by an actuating force against a restoring force exerted by the return spring results in an increase of the propelling force of the motor, and the restoring force of the return spring returns the accelerator pedal (11) toward its starting position when the actuating force subsides. A friction device (100, 200, 300, 400, 500, 600) generates a friction force that acts in addition to the restoring force. Alternatively, an electromechanical main actuator (18) produces an additional restoring force (FZusatz) that can be variably controlled using a control unit (12).
