摘要： 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.

摘要： In a steering device for a vehicle, the movement of a steering actuator driven by operation of an operating member is transmitted to vehicle wheels, in such a manner that the steering angle changes, without the operating member being coupled mechanically to the vehicle wheels. A first target yaw rate is calculated in accordance with the detected vehicle speed and a first steering angle set value, which corresponds to the detected amount of operation and vehicle speed. A second target yaw rate corresponding to the detected lateral acceleration and vehicle speed is calculated. A second steering angle set value, which corresponds to the difference between the detected yaw rate and a target yaw rate, as which the first target yaw rate or the second target yaw rate whichever has the smaller absolute value is taken, is calculated. The steering angle actuator is controlled in such a manner that the steering angle corresponds to the target steering angle, that is the sum of the first steering angle set value and the second steering angle set value.
