Zusammenfassung:PROBLEM TO BE SOLVED: To prevent an accidental variation in a wheel steering angle when a vehicle speed is changed during cornering at a constant steering angle. SOLUTION: In an operation method for superposition steering, a traveling speed is taken into consideration when determining a steering gear ratio so as to be able to change the steering gear ratio according to the traveling speed. In determining the steering gear ratio, the change of the traveling speed is taken into consideration only during steering motion when determining the steering gear ratio. COPYRIGHT: (C)2009,JPO&INPIT
