Abstract
The present invention is directed to a vehicle motion control system, which includes wheel brake cylinders, an automatic hydraulic pressure generating apparatus for generating a hydraulic braking pressure irrespective of operation of a brake pedal, a hydraulic pressure control valve device disposed between the pressure generating apparatus and the wheel brake cylinders to control the hydraulic braking pressure in each wheel brake cylinder, and a controller for controlling the pressure generating apparatus and the valve device in response to conditions of vehicle motion, and performing an automatically pressurizing control to the wheel brake cylinders at least when a brake pedal is not depressed, to perform a vehicle motion control. The controller is adapted to maintain the pressure generating apparatus to operate for a predetermined time period after the vehicle motion control was terminated, and control the valve device to shut off the communication between the pressure generating apparatus and the wheel brake cylinders, to modify the time period on the basis of the conditions of vehicle motion.
