ABSTRACT:
The invention is directed to a vehicle motion control system for maintaining vehicle stability by controlling the braking force applied to each wheel, in response to a condition of the vehicle in motion. A predetermined pressure increasing characteristic is provided for the hydraulic braking pressure which is supplied from a pressure control apparatus to wheel brake cylinders, on the basis of the vehicle condition, when the braking force controller initiates the control of the braking force to actuate the pressure control apparatus. And, a predetermined pressure decreasing characteristic is provided for the hydraulic braking pressure, when the braking force controller terminates the control of the braking force. The braking force controller is arranged to control the hydraulic braking pressure supplied from the pressure control apparatus to each wheel brake cylinder in accordance with the pressure increasing characteristic and the pressure decreasing characteristic to maintain the stability of the vehicle.
