Abstract
A difference in a longitudinal force indicating a difference between the longitudinal force acting on left and right wheels is obtained. A correction amount of the longitudinal force acting on each wheel is calculated based on the difference in the longitudinal force, and each wheel is independently controlled. When the difference in the longitudinal force is obtained, a speed increasing ratio of a front wheel steering angle for changing an overall steering ratio is calculated based on a preset control map and an input parameter including a vehicle speed and a lateral acceleration or the vehicle speed and steering wheel angle. A yaw moment to be generated around a weighted center of the vehicle is calculated based on the speed increasing ratio and a steering wheel angle of the vehicle as the input parameter. The difference in the longitudinal force is then calculated based on this yaw moment.
