Due to various reasons such as environmental protection, economy, controllability, etc., the current models of the market generally use electronic throttle accelerator. The so-called electronic throttle accelerator
is for the previous pull throttle. The traditional pull throttle uses a thin steel wire to directly connect the accelerator pedal to the throttle. They are connected, and the depth of the accelerator pedal directly corresponds to the opening and closing size of the throttle. The electronic throttle has no wire. It installs a potentiometer (variable resistor) in the pedal. The depth of the accelerator pedal is converted into the resistance of the resistor, and the electronic system of the car indirectly determines the depth of the accelerator pedal by sampling the resistance value. Finally, the stepping motor is driven by the ecu to control the opening of the throttle.
It is not difficult to find through the theory that the throttle is characterized by simple system and direct control. The accelerator pedal and the throttle are open at 1:1. On the contrary, The electronic throttle accelerator
is characterized by the accelerator pedal only characterizing the driver's operation intention, and the final throttle control was given to ecu. Simply put, the electronic throttle accelerator was born to alleviate the throttle lag.
