ABSTRACT:
A vehicle motion control apparatus is provided for performing a vehicle stability control on the basis of a parameter indicative of lateral margin for a tire on a road. The apparatus includes a steering control device for controlling a relationship between a steering angle and a tire angle to be varied, and a decelerating control device for controlling a vehicle speed to be decreased. The parameter indicative of lateral margin for the tire is monitored, and the steering control device and the decelerating control device are controlled on the basis of the monitored parameter. The steering control device is controlled to decrease the tire angle relative to the steering angle, when the parameter is decreased from a value of relatively large lateral margin to a value of relatively small lateral margin, which is smaller than a first threshold value, and the decelerating control device is controlled to decrease the vehicle speed in addition to the steering control by the steering control device, when the parameter is further decreased to a value of lateral margin smaller than a second threshold value, which is smaller than the first threshold value.
