Based on the unevenness of the road surface, the positions and speeds at which the left and right wheels of the front and rear wheels will be moved in the vertical direction are predicted using fuzzy reasoning before passing over the road surface, and the wheels are moved in accordance with the predictions. a fuzzy control unit that outputs a wheel control signal including a position and a moving speed; and a wheel control unit that outputs a wheel drive signal to each wheel drive unit individually in response to the wheel control signal from the fuzzy control unit. A wheel control system for a four-wheel independent suspension vehicle, characterized by comprising: and.
