Description

Accidentally stepping on the accelerator to suppress the accelerator and its operation method

The invention relates to a kind of behavior of accurately judging the driver's misstep on the accelerator pedal, and can instantly send the accelerator idling signal to make the engine control unit of the car return to the idling state, thereby preventing the vehicle from rushing, and thus maintaining the accelerator for traffic safety. Accidentally stepped on the suppressor accelerator.

Vehicle rush usually refers to the unintentional acceleration behavior that occurs when the car is stationary and ready to start. Because the vehicle rush is not the state expected by the driver, it often becomes the cause of traffic accidents.

The common reasons for vehicle rushing are mostly due to improper operation of the driver, because the accelerator pedal and the brake pedal of ordinary vehicles are usually set adjacent to each other to facilitate the driver to control, when the driver is slightly careless or nervous. In this state, it is very likely that when you want to brake, you accidentally step on the accelerator pedal, resulting in a violent accident.

When the travel signal of the accelerator pedal is reduced by at least 10%, the microcontroller cancels the accelerator idle speed signal.
