What is an electronic throttle?

The principle of electronic throttle and cable throttle is due to various reasons such as environmental protection, economy and reliability. Electronic throttle is widely used in newer models. The so-called electronic throttle is aimed at the previous cable throttle. The traditional cable accelerator connects the accelerator pedal and the accelerator directly, and the depth of stepping on the accelerator pedal directly corresponds to the opening and closing size of the accelerator. The electronic throttle has no cable. By installing a potentiometer (variable resistor) in the pedal, the depth of the accelerator pedal is converted into the resistance value of the resistor, and the electronic system of the automobile indirectly determines the depth of the accelerator pedal by sampling the resistance value. Finally, ecu drives the stepping motor to control the throttle opening. Through the principle comparison, it is not difficult to find that the cable accelerator is characterized by simple system and direct control, and the opening of the accelerator pedal and accelerator is1:1; The characteristic of electronic accelerator is that the accelerator pedal only represents the driver's operation intention, and the final accelerator control is given to ecu.
