<P>PROBLEM TO BE SOLVED: To provide a steering device for a vehicle that prevents a driver from imparted with incongruity feeling. <P>SOLUTION: The steering device for vehicle is a four-wheel active steering system that can vary a steered angle ratio of the steered wheel angle of a front wheel to the steering angle of a steering wheel, and can steer also rear wheels. When the load of a steered wheel actuator, which drives a steered angle ratio varying means for varying the steered angle ratio being a ratio between the steering angle of the steering wheel and the steered wheel angle of the front wheel has reaches than a predetermined given threshold or larger for a setup time or longer, the steered wheel actuator is controlled so that the steered angle ratio becomes a nearer value to 1 than the value at that time. <P>COPYRIGHT: (C)2011,JPO&INPIT |
