The present invention provides a graded braking control device and control method for vehicle tire burst, and belongs to the technical field of vehicles. It solves the problems of rear-end collision and more instability of the vehicle resulting from emergency brake after vehicle tire burst. The device includes a tire pressure sensor, a controller, a radar sensor, a stability detection module and an ESC, wherein the radar sensor and the stability detection module are respectively connected with input ends of the controller, the tire pressure sensor is in wireless connection with the controller, and the ESC is connected with an output end of the controller. The control method includes: 1. monitoring vehicle tire condition; 2. carrying out traffic state assessment and determining a first maximum braking deceleration value for preventing the rear-end collision with the follower vehicle after emergency brake of the present vehicle; 3. carrying out tire burst vehicle stability state assessment in combination with the current speed and setting the maximum braking deceleration under stable state; and 4. carrying out tire burst graded braking. The device and the method can ensure quick and stable braking of the tire burst vehicle, and avoid the rear-end collision of the present vehicle with the follower vehicle.
