The invention relates to the technical field of vehicle stability, and discloses a tire burst vehicle stability control method, system and device, a vehicle, equipment and a medium. Firstly, under the condition that a vehicle tire burst signal is determined to be generated and a vehicle control parameter is determined to be greater than a threshold value, an ideal deceleration and an ideal steering wheel angle are determined based on the vehicle speed when the vehicle tire is burst. Then, on the basis of the ideal deceleration, the ideal steering wheel angle and the track of the vehicle, the execution steering wheel angle parameter and the braking force corresponding to each wheel of the vehicle are determined; and finally, performing combined control on each wheel of the vehicle based on the braking force distribution corresponding to each wheel of the vehicle, and controlling a steering wheel angle controller based on execution of the steering wheel angle parameter, so that the vehicle driving state meets the stable condition, the tire burst condition is effectively dealt with, the limitation of single control is avoided, various tire burst working conditions are adapted, and the safety of the vehicle is improved. And particularly, the vehicle is kept stable under complex road conditions. Graded braking is achieved based on the vehicle speed during tire burst of the vehicle.
