PURPOSE:To run a truck in a predetermined direction without making the truck incline by controlling vehicle wheel acceleration so that vehicle wheel acceleration on a large acceleration side may be neared to vehicle wheel acceler ation on a small acceleration side in the case where acceleration difference between the truck advancing direction right side wheel and the left side wheel in generated. CONSTITUTION:Wheels 3a, 3b are provided at the lower ends of a truck 1 on whose frame 2 inside a pallet 4 is suspended through a wire 5, and detectors 8a, 8b top detect shift in regard to the guide line 6 of a guidance cable or the like provided on a road surface 7 are provided on the outside of the frame 2, and right and left travel motors are controlled so that the truck 1 may be run along the guide line 6 on the basis of the signals of the detectors 8a, 8b. Also, when the gravity center of a load on the pallet 4 is shifted, for example, onto the left side in regard to an advancing direction, the truck 1 has the tendency of traveling toward the left side, so the acceleration of the right side motor is controlled so that the acceleration of the right wheels 3a may be neared to the acceleration of the left wheels 3b.

In such a trackless carriage, when the center of gravity of the loaded luggage is displaced to the left with respect to the traveling direction, the left motor is rotated by the left wheel. Such a load becomes larger than the load of the right motor for rotating the right wheel. Therefore, as shown in FIG. 4, when the dolly accelerates from the stopped state to the maximum speed, the left wheel takes a longer time to reach the maximum speed than the right wheel, that is, the acceleration becomes smaller. As a result, the trolley will start to incline with its front part facing left with respect to the guideline. On the other hand, although the control device controls to increase the rotation of the left motor so that the accelerations of the left and right wheels are matched, the acceleration of the left wheel does not increase because the load of the left motor is large. The dolly will continue to run while tilting with respect to the guideline.
