PURPOSE:To eliminate errors of a route in the first travel when a carrier runs one travel route repeatedly by adding travel information storage means, a route information modifying means and a direction information storage means. CONSTITUTION:When the travel of a vehicle deviates from a target travel route, a travel control means M6 corrects the travel route. The corrected travel route is stored as travel information in the travel information storage means M7 and the route information modifying means M8 rewrites route information on the basis of the travel information. Accordingly when the vehicle runs the same route again, the deviation of the travel route arising previous time is eliminated. Where the vehicle runs according to the rewritten route information, the direction information storage means M9 stores a detecting signal outputted from a direction detecting means M2 as direction information and afterward the vehicle runs according to the direction information, while checking the vehicle direction. |
