Abstract
Upon detection of a potential transition from a low mu road surface to a high mu road surface, a rear wheel anti-lock brake system generates one dump pulse to increase the braking effort of the controller rear wheel as a test of the road surface. If the wheel accelerates following the test pulse, the transition is false and the anti-lock brake system continues as before. If the wheel does not accelerate following the test pulse, the transition is true and the anti-lock brake system proceeds to increase the braking effort of the controlled wheel brake.
