Abstract
Embodiments of the present application provide a vehicle control method and device, a vehicle body controller and a vehicle. The vehicle control method and device, the vehicle body controller and the vehicle realize the vehicle power-off and the turning-on of the hazard warning light at the same time by multiplexing the hazard warning light switch, which simplifies the operation process and improves the safety. On the other hand, the vehicle control method and device, the vehicle body controller and the vehicle do not need to add an additional power-off button, which reduces the production cost. At the same time, the vehicle control method and device, the vehicle body controller and the vehicle do not need to rely on the virtual switch in the vehicle display screen, thereby improving the reliability of the vehicle power-off. The vehicle control method comprises: detecting a pressing operation on the hazard warning light switch when the vehicle is in the ON gear; if the pressing time of the pressing operation is not less than a first set threshold or the pressing frequency of the pressing operation is not less than a second set threshold, obtaining the real-time vehicle speed; if the real-time vehicle speed represents that the vehicle is in a running state, controlling the low-voltage electrical equipment in the vehicle to power off, and controlling the hazard warning light to enter a working state.
