Abstract
The application discloses a vehicle stability control method, device and equipment and a vehicle, and relates to the technical field of vehicle control. The vehicle stability control method comprises the following steps: in response to triggering of a crosswind stability compensation mechanism of a vehicle, acquiring an actual yaw angular velocity of the vehicle at a driving speed and a theoretical yaw angular velocity of the vehicle at the driving speed; determining a front wheel compensation angle of the vehicle according to the actual yaw angular velocity and the theoretical yaw angular velocity through a vehicle stability control mapping diagram; and compensating a front wheel steering angle of the vehicle through the front wheel compensation angle to keep the vehicle stable. In this way, when the crosswind stability compensation mechanism of the vehicle is triggered, the front wheel compensation angle of the vehicle can be determined according to the actual yaw angular velocity and the theoretical yaw angular velocity through the vehicle stability control mapping diagram to compensate the front wheel steering angle of the vehicle, so that the complexity of the vehicle stability control method can be reduced, and the stability of vehicle driving can be improved.
