<p>An accelerator pedal unit is known comprising an accelerator pedal, an actuator, and a control shaft via which the actuator can transmit a restoring torque to the accelerator pedal. The accelerator pedal unit can generate an additional restoring force which acts on the accelerator pedal, for example in order to regulate or limit the speed of a vehicle or to function as a warning device in the event of speeding. Disadvantageously, the actuator and the accelerator pedal are rigidly coupled to each other. As a result, brief losses of torque of the actuator, for example losses of torque of a brushed DC electric motor, are transmitted to the accelerator pedal with no change in their relative magnitude and are noticeable to the driver in a disruptive manner. In the accelerator pedal unit according to the invention, the actuator is mechanically decoupled from the accelerator pedal. According to the invention, the torque of the control shaft (3) is transmitted to the accelerator pedal (1) via a damping element (10).</p> |
