Abstract
An ECU ( ) of a vehicle executes under-steering control when a steering wheel is operated in the direction to increase the steering angle under an under-steering state and the yaw rate does not increase. The under-steering control is not executed under such a driven under-steering state that the vehicle is cornering while applying the engine power to the driven wheels. The under-steering control is executed only under such a condition that although the steering wheel is operated in the direction to increase the steering angle, the actual yaw rate &phgr; does not change and not follow the operation. Thus, in the vehicle, when the under-steering control for restraining the under-steering state or the over-steering control for restraining the over-steering state is executed during the cornering motion of the vehicle, the condition for executing the under-steering control or the over-steering control is adequately set. In consequence, it is prevented that the driver feels a malaise due to the excessively earlier or later execution of the control so that both of higher safety and driving characteristics may be obtained.
