VEHICLE BRAKING SYSTEM

摘要

A vehicle braking system including a controller, in an initial anti-skid cycle, performs a first determination to select a high or a low control mode in accordance with wheel speed parameters. The controller in a second, or subsequent anti-skid cycle, performs a second determination to determine whether a near mu test is to be performed in accordance with wheel speed parameters. The controller consequent upon selection of low control mode performs a near mu test. The near mu test includes performing a rise in the brake pressure and then selecting a high or low mode in accordance with the speed of the wheels resulting from the rise in brake pressure in the near mu test.
