The aim is to stably control the lateral movement of a vehicle even on a road where the frictional coefficient is extremely small, such as on a frozen road, thereby improving the turnability and travelling stability. The device includes a frictional force adding means for increasing the frictional force of wheels to a road surface by scattering particulates and a controller which calculates the target lateral movement value and the actual lateral movement value based on the signals from wheel speed sensors, a steering angle sensor and a yaw rate sensor and actuates the right or left frictional force adding means according to the difference between these two values to increase the frictional force, thereby stabilizing the lateral movement.
