Abstract

The present invention is directed to a vehicle motion control system for maintaining vehicle stability by controlling the braking force applied to at least one of the front and rear wheels of a vehicle. Oversteer restraining control and/or understeer restraining control are performed by applying the braking force to at least one wheel, on the basis of a condition of the vehicle in motion and irrespective of depression of a brake pedal. In the oversteer restraining control, the braking force is applied to at least one wheel so as to cause an increase in turning radius, when an excessive oversteer occurs during vehicle motion. Whereas, in the understeer restraining control, the braking force is applied to at least one wheel so as to cause a decrease in turning radius, when an excessive understeer occurs during vehicle motion. When the excessive oversteer and excessive understeer occur simultaneously or sequentially during vehicle motion, priority is given to the oversteer restraining control over the understeer restraining control with respect to at least one of the front wheels, while priority is given to the understeer restraining control over the oversteer restraining control with respect to at least one of the rear wheels.
