A kind of four-wheel steering system is introduced, which is powered hydraulically and controlled by a single piece processor. This system is different from current steering system in all aspects. When a turning action occurs, the four wheels turn simultaneously, and every wheel can turn in the range of 180 deg angle. Under the control of the single piece processor, the vehicle body can move in any direction with given form and no dead zone in the range of 360 deg. The wheels are driven by rack cylinders which are controlled by proportional direction valve and powered by a hydraulic station. This system is suitable for any load, and the synchronism tolerance of the four wheels is less than 2.1 deg.
