An improved anti-lock brake control method adaptively determines exit criteria for terminating anti-lock brake control based on rate of brake pedal release and estimates of the brake torque and road surface coefficient of friction. The brake torque and road surface coefficient of friction are estimated based on a periodically updated characterization of the relationship between brake pedal position and vehicle deceleration.

1. A method of operation for a vehicle braking system including a driver manipulated brake pedal and an ABS system for modulating vehicle braking when activated based on an ABS command, the method comprising the steps of:detecting a rate of change in brake pedal movement when the driver is releasing the brake pedal; biasing the ABS command toward deactivation of the ABS system in response to the detected rate of change in brake pedal movement when the ABS system is activated; deactivating the ABS system if the ABS command indicates that the ABS system should be deactivated for at least an exit time interval.
