Traction vehicle stability monitoring method, vehicle and device

The invention provides a method, vehicle and device for monitoring the stability of a towed vehicle, and the method comprises the steps: obtaining target distance values at a plurality of moments, and enabling the target distance values to represent the distance between a vehicle radar and the towed vehicle; and determining the stability of the towed vehicle according to the target distance values at the multiple moments. Thus, the vehicle-mounted radar of the vehicle is used for detecting the stability of the towed vehicle, the problem that the detection precision is reduced due to sensor damage caused by external factors is solved, and the universality of the vehicle for monitoring the stability of the towed vehicle is improved.
