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 driven wheels and non-driven wheels of a vehicle. A vehicle motion control is 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. 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, 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. In the case where an excessive braking to at least one of the driven wheels is detected, when an engine brake is exerted on the vehicle, a correction control is performed to increase the braking force applied to at least one of the non-driven wheels. For example, when an excessive slip rate of at least one of the driven wheels is detected, a desired slip rate of at least one of the non-driven wheels is corrected.
