Abstract: A vehicle motion state control device controls an actuator capable of regulating a vehicle motion state so that an actual yaw rate approaches a target yaw rate determined based on a steer angle and a vehicle speed, target yaw rate limit values for left and right turn directions of a vehicle are individually determined by a target yaw rate limit value determining mechanism based on detected lateral acceleration, detected vehicle speed, and predetermined set minimum lateral acceleration set in a direction opposite to that of the detected lateral acceleration; and target yaw rates for the left and right turn directions are determined by a target yaw rate determining mechanism 5 while limiting them by the determined target yaw rate limit values. Thus, an over steer control is started at an early timing when an abrupt steering operation at a large steer angle occurs which causes a phase difference to the yaw rate and the lateral acceleration.
