Abstract
In a steering device for vehicle, the movement of a steering actuator, which is driven in accordance with the rotating operation of an operating member, is transmitted to the vehicle wheels such that the steering angle changes without mechanically coupling the operating member to the wheels. A target yaw rate, which accords with a load torque, that is sum of the control torque generated by an operating actuator and driver operating torque, and an operating angle of the operating member resulting from the functioning of this load torque, are computed. The steering actuator is controlled such that the vehicle yaw rate follows the target yaw rate. The operating actuator is controlled such that the operating angle follows a target operating angle of the operating member corresponding to a behavior index value comprising at least yaw rate of the vehicle.
