摘要： 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.

摘要： 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.

摘要： The present invention is directed to a vehicle motion control system for maintaining vehicle stability by controlling the braking force applied to each wheel of a vehicle. The braking force applied to each wheel is controlled on the basis of outputs of the wheel speed sensors and the vehicle speed estimation unit. A limit value is calculated to a difference between a first estimated vehicle speed calculated for a second wheel located on the right side of the vehicle and a left estimated vehicle speed calculated for a left wheel located on the left side of the vehicle. The calculation of one of the first and second estimated vehicle speeds is limited in response to the limit value, so as to keep the estimated vehicle speed calculated for one of the right and left wheels rotating at a relatively low speed to be greater than a value subtracting the limit value from the second estimated vehicle speed provided for the other one of the right and left wheels rotating at a relatively high speed. For example, the limit value is calculated on the basis of a varying value resulted from at least a change in a coefficient of friction for each wheel of the vehicle, and varied in accordance with one of a plurality of control modes.
