Abstract:
1. An accelerator pedal unit comprising: (a) a base element; (b) a pedal element that may be displaced with respect to the base element along an actuation direction (B); (c) a rotating element that is linked to the pedal element such that said rotating element rotates upon displacement of the pedal element; (d) at least one return element to return the pedal element in a direction opposite to the actuation direction (B); (e) an electric drive device with a rotor and a stator element to create opposing force against pedal depression, said rotor and said rotating element being mounted adjacent to each other along a common axis; and (f) a freewheel clutch unit, positioned between the rotor and the rotating element, for coupling the rotor and the rotating element, upon actuation of the pedal element along the actuation direction (B), such that the opposing force generated by the electric drive device acts on the pedal element, but which allows separate motion opposite the actuation direction (B); (g) a rotation sensor, coupled to the rotating element, positioned along an extension of the common axis of the rotor and the rotating element.
