<p>The present invention realizes a stable steering system by steering a vehicle using a steering motor during usual time, and transmitting a steering force of a steering wheel to the a driving wheel using a hydraulic pressure in case of an error in the system. In addition, introduced is a steering system by a wire which can provide driving stability and reliability by preventing an error from occurring in a steering operation due to the lack of hydraulic pressure as the oil flows back to a reservoir when steering the steering wheel using the hydraulic pressure.</p> |
