The invention provides a vehicle tire burst classifying brake control device and a control method, and belongs to the technical field of automobiles. The device and the method solve the problems that tailgating happens and a vehicle becomes more unstable due to emergency braking after tire burst of the vehicle. The vehicle tire burst classifying brake control device comprises a tire pressure sensor, a controller, a radar sensor, a stabilization detecting module and an ESC. The radar sensor and the stabilization detecting module are respectively connected to the input end of the controller, the tire pressure sensor is in wireless connection with the controller, and the ESC is connected with the output end of the controller. The control method includes the first step of monitoring conditions of vehicle tires, the second step of carrying out traffic condition assessment and determining a first maximum braking deceleration value preventing tailgating of a rear vehicle after the tire burst vehicle carries out emergency braking, the third step of carrying out tire burst vehicle stable state assessment by combining the current vehicle speed and working out the maximum braking deceleration based on the stable state, and the fourth step of carrying out tire burst classifying braking. The device and the method can ensure the quick and stable braking of the tire burst vehicle and prevent tailgating from happening between the rear vehicle and the tire burst vehicle.
