Abstract

If an obstacle (74) is detected, its position is stored in obstacle memory unit (41) on the assumption that the obstacle (74) is common to a plurality of vehicles (2, 2). As vehicles (2, 2) pass by, the content of the obstacle memory unit (44) is updated. When the vehicles (2, 2) are supplied with position data of the respective goal point (72, 72), the vehicles (2, 2) are guided by their goal point (72, 72) in accordance with the content of the obstacle memory unit (41) so that they can avoid the obstacle (74). Vehicles can be thus guided to avoid obstacles by knowing the existence of obstacles in the working sites where the positions of obstacles are always different.
