Abstract
A vehicle control device incorporating an electric power steering is provided, wherein an extraordinary yaw motion acting on a vehicle is detected and is suppressed or moderated, so that the stability of the vehicle in a straight-ahead steering is improved. The causes of the extraordinary yaw motion are one of lateral wind, asymmetrical surface state of the road, lateral slant of the road and the like. A countermeasure against the extraordinary yaw motion is taken by applying a counter (opposite direction) yaw motion on the vehicle or switching over the control mode from a proportional control to a proportional integral control.
