Abstract
In a vehicle with first and second front vehicle wheels and third and fourth rear vehicle wheels and at least one member of a first group comprising anti-lock brake control and positive acceleration traction control, a brake control method comprising the steps of: determining a desired vehicle yaw rate; determining an actual vehicle yaw rate; responsive to the desired and actual vehicle yaw rates, determining an axle command; responsive to the desired and actual vehicle yaw rates, determining a torque command; applying the axle command during activation of one of the anti-lock brake control and the positive acceleration traction control to one member of a second group comprising (i) the two front wheels and (ii) the two rear wheels, wherein wheel-to-road traction is increased and a difference between desired vehicle yaw rate and actual vehicle yaw rate is minimized; and applying the torque command to at least one of the vehicle wheels independently of the axle command to create a yaw torque moment on the vehicle body, wherein the difference between the desired vehicle yaw rate and the actual vehicle yaw rate is minimized.
