When a curve exists in the direction of travel of a vehicle and information for this curve is inputted from a navigation system and the shape of the actual curve in the road changes gently with respect to the curve shape of the navigation system, the change in the curvature of the actual curve actually becomes smaller based on an integral value of the yaw rate, vehicle speed, and the yaw rate. It is then detected that the navigation system and the actual vehicle behavior of the system do not coincide, and the output of unnecessary control commands such as alarms, deceleration and steering and the like is halted. Namely, it is judged that curve information from the navigation system is erroneous, and outputting of unnecessary control commands can be avoided before something happens.
