Common faults of electronic accelerator pedal

The accelerator pedal is the key component of the electronic accelerator automatic control system. Its basic principle is to convert the data signal needed by the accelerator pedal into the current data signal according to the pedal phase sensor and send it to ECU. ECU calculates the optimal throttle opening by integrating the current speed, distance judgment, throttle opening, vehicle speed and other information. The ECU controls the torque of the DC brushless motor, continuously adjusts the throttle opening of the electronic device, and the throttle phase sensor reports the data signal of the throttle position to the ECU to generate a closed-loop control system, which finally stabilizes the throttle of the electronic device to the optimal opening.

Common problems of accelerator pedal of electronic equipment

The common faults of the accelerator pedal of electronic equipment are easy to cause abnormal pedaling noise or poor pedal return, which is also extremely dangerous. The common faults of accelerator pedal in most electronic devices are caused by accelerator pedal sensors. If the accelerator pedal sensor is faulty or damaged, the fault indicator will flash, and the ECU will not be able to identify the size of the accelerator pedal, which will lead to idling jitter, stuck accelerator pedal, insufficient fuel supply and so on, which will lead to the abnormal application of the automobile.

As a key component of electronic accelerator automatic control system, the performance of electronic accelerator pedal not only affects the driving force, comfort and rationality of gasoline and diesel, but also affects the safe driving of automobiles. Once there is a problem, it is necessary to complete the maintenance immediately and replace it if necessary, so the most important thing is to ensure driving safety.
