Working principle of electronic accelerator pedal
The working principle of electronic accelerator pedal mainly involves using wire harness (wire) instead of traditional mechanical cable or rod, installing a micro motor at the throttle valve, and driving the throttle valve opening through the motor. This process is also called "wire driving", which replaces the original mechanical transmission mechanism with wire. Specifically, the working principle of electronic accelerator pedal includes the following key steps:
When the driver steps on the accelerator when he needs to accelerate, the pedal position sensor will sense this action and transmit the signal to the electronic control unit (ECU) through the cable.
After receiving the signal, the ECU analyzes and judges it, and sends a command to the drive motor.
The drive motor controls the throttle valve opening according to the ECU's command to adjust the flow of combustible mixture.
When the load is high, the throttle valve opens wide and more combustible mixture enters the cylinder. The electronic throttle can analyze and compare various data collected by the sensor through the ECU, and issue instructions to the throttle actuator to move the throttle to the best position, so as to achieve a state close to the theoretical air-fuel ratio under different loads and working conditions, so that the fuel can be fully burned.
In addition, the electronic throttle pedal also uses a non-contact electronic throttle pedal designed based on the Hall effect principle. The relative movement of the magnet and the Hall sensor causes the magnetic induction intensity acting on the Hall sensor to change, causing the output signal to change, thereby realizing the electronic control of the throttle function. The electronic throttle system is mainly composed of the throttle pedal, pedal displacement sensor, ECU (electronic control unit), data bus, servo motor and throttle actuator. Its working process is accurate and fast, and more ECU intervention can be added to facilitate the linkage of other electronic control auxiliary functions, and there is no problem of mechanical wear.
