<p>PROBLEM TO BE SOLVED: To attain cost reduction by eliminating an address plate for controlling right and left turning signal for an unmanned running vehicle, especially an address plate for turning-off. SOLUTION: Within the control region of the rotational speed of a motor due to a guide tape position (dislocation), a straight driving control region set at a range where dislocation quantity is small and a difference the rotational speeds of right and left motors is smaller than first setting value (ΔVs), and a right and left turning control region is set at a range where dislocation quantity is large and a difference between the rotational speeds of the rights and motors is larger than the second setting value (ΔVt) which is larger than the first setting value. After lamps 9A, 9B, 10A, 10B for right and left turning display turned on according to the right/left turning command of the address plate just before a branched point, the lamps are turned off when a vehicle has a curve and has entered a straight control region.</p> |
