ABSTRACT:
A method and system are disclosed for controlling an anti-lock brake system based on vehicle deceleration. The system includes a wheel speed sensor and control unit for performing the method steps of sensing a wheel speed and determining a wheel deceleration and a vehicle deceleration therefrom. The control unit also performs the method steps of determining an initial deceleration threshold representing a pre-lockup condition, determining a final deceleration threshold based on the vehicle deceleration, comparing the wheel deceleration to the final deceleration threshold, and activating the vehicle anti-lock brake system if the wheel deceleration exceeds the final deceleration threshold.
