PROBLEM TO BE SOLVED: To prevent excessive control due to a decrease in the accuracy of computing a vehicle speed in a vehicle motion control device which calculates the angular velocity of revolution about the turning center of the vehicle by dividing lateral acceleration by the vehicle speed computed according to wheel speeds detected by a plurality of wheel speed detection means detecting the speeds of wheels, and which controls the yawing motion of the vehicle according to the rate of change of a side-slip angle which is the difference between the angular velocity of the revolution and a yaw rate. SOLUTION: A revolution angular velocity computing means 61 includes a division means 80 which divides lateral acceleration by a vehicle speed computed by a vehicle speed computing means and a low speed correction means 83 which, when the vehicle speed obtained by the vehicle speed computing means is as low as less than a set speed, corrects the value obtained by the division means 80, according to the vehicle speed obtained by the vehicle speed computing means, by setting the rate of a change of a side-slip angle at a small value including zero. |
