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.

Abstract: A method is provided for detecting a rollover event of a vehicle. A lateral kinetic energy of the vehicle is determined in response to vehicle longitudinal velocity and vehicle side slip angle. A lateral acceleration of the vehicle is measured. A rollover potentiality index is determined in response to the lateral kinetic energy and the lateral acceleration. A rollover index is determined by weighting the rollover potentiality index by a factor of the lateral acceleration. A comparison is made to determine if the rollover index is above a predetermined threshold.
