Steering device for vehicle

摘要

A steering device for a vehicle wherein the movement of a steering actuator (2) is transmitted to the wheels (4) of a vehicle in such a manner that the steering angle changes in accordance with this movement, without the operating member (1) being coupled mechanically to the vehicle wheels (4). A behaviour index value corresponding to change in the behaviour of the vehicle due to change in the steering angle is determined, and a target behaviour index value corresponding to the amount of operation of the operating member (1) is calculated. A steering angle correction value corresponding to the differential between the target behaviour index value and the determined behaviour index value is summed with a steering angle set value corresponding to the target behaviour index value to give a target steering angle. The steering actuator (2) is controlled in such a manner that the steering angle corresponds to the target steering angle. <IMAGE>
