<p>Left and right rear wheels (16B) are controlled independently and the traveling direction of a vehicle (10) is altered (turned) by the speed difference. A steering wheel is normally provided and steered constantly by a crew; but since the vehicle (10) can be turned automatically with an optimal curvature by simply tilting an operating stick (92) previously to the left or right thereby designating the turning direction, troublesome steering operation of the crew can be eliminated. Since the left and right rear wheels are controlled independently through PLL control, the vehicle can be turned accurately with good response.</p> |
