Abstract
A vehicle motion control system which generates a minimized switching noise when a hydraulic pressure control valve is switched. The vehicle motion control system includes an automatic hydraulic pressure generator generating a hydraulic pressure irrespective of a brake pedal operation and a hydraulic pressure control valve adjusting the hydraulic brake pressure by opening or blocking a connection between the automatic hydraulic pressure generator and a wheel brake cylinder, and performs a motion control by controlling at least the hydraulic pressure control valve in accordance with the motion of a vehicle. The vehicle motion control system has a hydraulic pressure sensor detecting a generated hydraulic pressure of the automatic hydraulic pressure generator, setting a necessary hydraulic pressure for control, and adjusting the generated hydraulic pressure of the automatic hydraulic pressure generator by controlling the automatic hydraulic pressure generator in accordance with the result of a comparison between the actually generated hydraulic pressure of the automatic hydraulic pressure generator and the necessary hydraulic pressure for the motion control.
