Abstract
When the absolute value of the steering angle equals or is greater than a prescribed angle, a vehicle motion control apparatus sets a control gear ratio so that when an estimated vehicle-body speed is equal to or greater than a prescribed value, the control gear ratio becomes a value equal to or greater than a certain value and which increases with estimated vehicle-body speed as the absolute value of the steering angle increases. When the estimated vehicle-body speed is less than the prescribed value, the control gear ratio becomes a value not greater than the certain value and which decreases with estimated vehicle-body speed as the absolute value of the steering angle increases. The apparatus then calculates a target yaw rate making use of the control gear ratio, and controls a braking force applied to each wheel so that the actual yaw rate coincides with the target yaw rate.
