Abstract
An anti-lock braking system having an anti-lock braking control which periodically increases the speed of the engine during the anti-lock mode of operation. The anti-lock braking control detects the deceleration of the driven wheel speed when each periodic increase in engine speed is terminated, to detect the transition in the driven wheels from a low friction road surface to a high friction road surface. Upon the detection of the transition to a high friction road surface, the anti-lock brake control terminates the increased engine speed and increases the brake fluid pressure to the driven wheel actuators to maintain maximum anti-lock braking torque.
