BYD f3 can't afford to refuel (the reason why BYD f3 hot car is difficult to start)

The reason why BYD f3 hot car can't refuel: the electronic throttle of the car is out of order. The electronic throttle uses wire harness (conductor) instead of cable or pull rod, and a micro motor is installed on the other side of the throttle to drive the throttle to open, which is called conductor drive, and the original mechanical transmission mechanism is replaced by conductor.

The electronic accelerator control system is mainly composed of accelerator pedal, pedal displacement sensor, ECU (electronic control unit), data bus, servo motor and accelerator actuator. The displacement sensor is installed inside the accelerator pedal, which can monitor the position of the accelerator pedal at any time.

When it is detected that the height and position of the accelerator pedal change, the information will be sent to the electronic control unit immediately. The electronic control unit will calculate and process these information and data information from other systems to calculate the control signal, which will be sent to the servo motor relay through the line. The servo motor drives the throttle actuator, and the data bus is responsible for the communication between the system ECU and other ECU.

Because the throttle is adjusted by the electronic control unit, the electronic throttle system can set various functions to improve driving safety and comfort.
