PURPOSE:To attain branching with a command issued on a truck by applying a DC signal to a steering control circuit of the truck according to the branching direction and giving deviation to the drive of the truck. CONSTITUTION:A plus or minus DC signal is produced according to the branching direction by a branch signal generating circuit 64 and by turning on a selection switch 643 or 644. Thus a branch signal is delivered 647. This output 647 is applied to a deviation amplifier circuit 65. As a result, a steering wheel 68 is deviated forcibly to the right or left side of a guide line. Under such conditions, a truck passes through a branch point. Thus the truck can be branched in a deviated direction to the guide line buried into a floor by the branch signal. This can omit the branch switching equipment on the ground. Then the branching is possible according to an operation command issued on the truck. |
