MOTION CONTROL DEVICE OF VEHICLE

In the case where the absolute value of steering angle &thetas;s is equal to or greater than a prescribed angle, a motion control apparatus 10 for a vehicle sets a control gear ratio n in such a manner that when an estimated vehicle-body speed Vso is equal to or greater than a prescribed value, the control gear ratio n becomes a value which is equal to or greater than "20" and which increases with the estimated vehicle-body speed Vso as the absolute value of the steering angle &thetas;s increases, and when the estimated vehicle-body speed Vso is less than the prescribed value, the control gear ratio n becomes a value which is not greater than "20" and which decreases with the estimated vehicle-body speed Vso as the absolute value of the steering angle &thetas;s increases. The apparatus then calculates a target yaw rate Yrt by making use of an equation shown in Step 510 and using the control gear ratio n, and controls a braking force applied to each wheel so that the actual yaw rate Yr coincides with the target yaw rate Yrt.
