Summary:PURPOSE:To attain the optimum turning of an unmanned guide truck at a speed corresponding to the turning radius by controlling the guide truck when it travels at a turning part after detecting the angle deflection between the truck and a guide line. CONSTITUTION:When an unmanned truck travels at a turning part, the angle deflection between the guide truck and a guide line which is varied in response to the turning radius is detected. A control circuit 18 controls speed commands EL and ER of right and left wheels 11a and 12a as VS-VA-VP and VS- VA+VP respectively by means of a speed command VS, an angle signal VA and a position signal VP. The signal VA increases as the turning radius is decreased and the angle deflection is increased respectively. Then both commands EL and ER are reduced. As a result, the guide truck can travel at a turning part at an optimum speed.
