[0002] At present, the electronic accelerator for passenger car is divided into two types of with hysteresis force and without hysteresis force. The electronic accelerator with hysteresis force can provide damping force when the accelerator returns to the original position, thus producing hysteresis, and the driver's leg force is relatively small, and the driving is more comfortable, especially for long distance driving. In order to provide such damping force, a damping mechanism needs to be added to the electronic accelerator.
