ABSTRACT:
The present invention is directed to a vehicle motion control system for maintaining stability of an automotive vehicle when the vehicle is in motion, by controlling a hydraulic braking pressure control apparatus to control a hydraulic braking pressure in each of wheel brake cylinders operatively mounted on each wheel of the vehicle to control a braking force applied thereto. A steering control unit and an anti-skid control unit are provided for actuating the apparatus to control the braking force applied to at least one of the wheels, respectively. A pressure increase compensating unit is provided for controlling a pressure increasing rate for increasing the braking pressure in at least one of the wheel brake cylinders to a desired pressure which is set after the pressure decreasing operation when the braking pressure with respect to at least one of the wheels is controlled in accordance with the control performed by the steering control unit and the control performed by the anti-skid control unit simultaneously, to be greater than a pressure increasing rate for increasing the braking pressure to the desired pressure in accordance with the control performed only by the anti-skid control unit.
