After the electronic control unit 20 receives the vehicle interior and exterior information of the vehicle, the electronic control unit 20 may automatically control the mistaken stepping on the accelerator pedal to open and send a prompt message to the driver according to the vehicle interior and exterior information of the vehicle and the stepping operation.
The function of stepping on the accelerator pedal by mistake has two states of opening and closing, and the driver can control the opening and closing of the function of stepping on the accelerator pedal by mistake. When the function of stepping on the accelerator pedal by mistake is started, the detection module 10 can automatically detect the stepping depth and/or the stepping average acceleration of the accelerator pedal, the detection module 10 can send detection information to the electronic control unit 20, and the electronic control unit 20 can control whether the vehicle executes braking operation according to the stepping depth and/or the stepping average acceleration, so that the situation that the accelerator is mistakenly stepped on as the brake can be avoided, traffic accidents can be prevented from occurring, and the running safety of the vehicle can be improved. When the function of stepping on the accelerator pedal by mistake is closed, the related function modules in the vehicle can automatically detect the information inside and outside the vehicle body of the vehicle, and the electronic control unit 20 can send prompt information and/or automatically control whether to start the function of stepping on the accelerator pedal according to the information inside and outside the vehicle body and the operation of stepping on the accelerator pedal, and the prompt information can be sent to remind a driver of the function of stepping on the accelerator pedal to be in a closed state, so that traffic accidents can be avoided when the driver forgets to start the function of stepping on the accelerator pedal, and the driving safety of the vehicle can be further improved.

5. The control method for preventing the accelerator pedal from being stepped on mistakenly according to claim 2, wherein when the function of stepping on the accelerator pedal mistakenly is turned off, the control method comprises the steps of detecting information inside and outside a vehicle body of the vehicle, and prompting and/or automatically controlling the function of stepping on the accelerator pedal mistakenly according to the information inside and outside the vehicle body and the operation of stepping on the accelerator pedal, and comprises the following steps: and detecting sound decibel information in the vehicle, and controlling the function of opening the accelerator pedal mistakenly stepped and sending alarm prompt information if the actual sound decibel value exceeds the preset sound decibel value and the average stepping acceleration is greater than the second threshold value within third preset time.
6. The control method for preventing the accelerator pedal from being stepped on mistakenly according to claim 2, wherein when the function of stepping on the accelerator pedal mistakenly is turned off, obstacles around the vehicle are detected, and when the fact that the spacing distance between the obstacles and the vehicle is smaller than a second preset distance and/or the stepping average acceleration is larger than a second threshold value is detected, the vehicle is controlled to perform a braking operation and alarm prompt information is sent out.
7. The control method for preventing false stepping of an accelerator pedal according to claim 5 or 6, wherein if the stepping average acceleration is not detected to be greater than the second threshold value, the false stepping function is turned off for a fourth predetermined time.
8. The control method for preventing the accelerator pedal from being stepped on mistakenly according to claim 1, wherein the function of stepping on the accelerator pedal mistakenly is started, and when the vehicle is detected to run uphill, the vehicle is controlled to send out prompt information to prompt a user that the function of stepping on the accelerator pedal mistakenly is in a starting state.
9. The control method for preventing the accelerator pedal from being stepped on mistakenly according to claim 1, wherein a driver controls the function of stepping on the accelerator pedal mistakenly to be turned on or off through a switch device.
10. A vehicle characterized by comprising the control method for preventing false stepping of an accelerator pedal according to any one of claims 1 to 9.
