Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to an electronic accelerator pedal assembly. Background technique [0002] The accelerator pedal is an automobile component to be controlled when the automobile accelerates. It can control the oil intake of the motor vehicle cylinder and then control the speed and power of the engine, and finally realize the control of the speed of the motor vehicle. The traditional accelerator pedal assembly mostly realizes the accelerator opening control through a connecting rod or a cable, and its series of actions are all mechanical movements. As we all know, the transmission accuracy and sensitivity of mechanical motion cannot meet a very high requirement, so the traditional accelerator pedal assembly cannot achieve the technical purpose of precise control of the accelerator, and the pedal needs to be in frequent contact with the foot, so the wear resistance of the pedal is very high Theref...
