发明名称 MOTOR VEHICLE BRAKE PRESSURE CONTROL APPARATUS WHEREIN BRAKE PRESSURE IS CONTROLLED BASED ON OVERSHOOT DROP OF WHEEL SPEED UPON LOWERING OF BRAKE PRESSURE
摘要 A brake pressure control apparatus for regulating a brake pressure for braking a wheel of a motor vehicle, the apparatus including a device, for obtaining a wheel speed, a device for obtaining a reference wheel speed, on the basis of a vehicle speed, a commanding device for generating brake control commands for regulating the wheel brake pressure, and a pressure regulator for regulating the brake pressure according to the brake control commands, the apparatus further including an overshoot obtaining device for obtaining an estimated amount of an overshoot drop of the wheel speed, which overshoot drop is estimated to occur after commencement of a decrease of the brake pressure, so that the commanding device generates the brake control commands depending upon whether the wheel speed is higher or lower than a critical wheel speed, that is, the reference wheel speed minus the estimated amount of the overshoot drop of the wheel speed.
