Abstract
A steering actuator can be controlled such that the ratio between amount of operation of an operating member and amount of steering of vehicle wheels changes. Movement of the steering actuator is transmitted to the vehicle wheel such that variation in steering angle is generated. A relationship between behavior index value for operating corresponding to change in behavior of the vehicle caused by change in steering angle, target behavior index value for operating corresponding to amount of operation of the operating member, and target operating torque is stored. The target operating torque is calculated from the stored relationship, the determined behavior index value for operating, and the determined target behavior index value for operating. An operating actuator for generating torque which acts upon the operating member is controlled such that the operating torque of the operating member corresponds to the target operating torque.
