Among them, the radio frequency receiving circuit is used to receive the control signal sent by the remote control and send the control signal to the MCU, the vibration detection circuit is used to collect the vibration signal when the vehicle vibrates abnormally and send the vibration signal to the MCU, the steering detection circuit, the reversing detection circuit and the overspeed detection circuit are used to collect the steering, reversing and overspeeding signals and send them to the MCU, the MCU is used to obtain the vehicle status information, and when receiving the control signal sent by the remote control, it is determined whether the electric vehicle needs to be locked; if it is determined that the electric vehicle needs to be locked, a first lock motor signal is generated and the first lock motor signal is sent to the motor control circuit; the motor control circuit controls the motor of the electric vehicle to stop running; if it is determined that the electric vehicle does not need to be locked, no instruction is sent.
