ABSTRACT:
An anti-lock brake controller that is operable, upon detecting a potential wheel lock-up situation during a vehicle braking cycle, to cycle apply and dump valves associated with vehicle rear wheels continuously between apply and dump modes to determine an estimated maximum friction wheel slip. The controller then is further operable to utilize the estimated maximum friction wheel slip to determine reference velocities that are used to continuously control apply and dump valves associated with the vehicle front wheels to optimize vehicle braking.
