Abstract: A vehicle includes a system performing a method of controlling an operation of the vehicle during a tire blowout. The system includes a vehicle dynamics sensor for detecting a dynamic parameter of the vehicle, tire sensors for detecting wheel speeds of wheels of the vehicle, and a processor. The processor is configured to receive a velocity of the vehicle from the vehicle dynamics sensor and the wheel speeds from the tire sensors, determine a diagonal product ratio of the wheel speeds, compare the diagonal product ratio to a range to detect an occurrence of a tire blowout, identify a location of the tire blowout from a wheel speed ratio based on wheels that are diagonally opposite each other, and control the operation of the vehicle in response to the tire blowout.
