  • Method for providing enhanced stability of a vehicle with a deflated tire
    Patent number: 7677095
    Abstract: In a motor vehicle equipped with pneumatic tires and a hydraulically actuated wheel brake system, a method for enhancing stability of the vehicle by determining whether any tire on the vehicle is deflated, determining the current magnitude of brake pressure at the wheel of the deflated tire when the brakes are applied, and reducing the current magnitude of brake pressure at the wheel of the deflated tire.
