Abstract
If an obstacle ( ) is detected, its position is stored in obstacle memory unit ( ) on the assumption that the obstacle ( ) is common to a plurality of vehicles ( ). As vehicles ( ) pass by, the content of the obstacle memory unit ( ) is updated. When the vehicles ( ) are supplied with position data of the respective goal point ( ), the vehicles ( ) are guided by their goal point ( ) in accordance with the content of the obstacle memory unit ( ) so that they can avoid the obstacle ( ). 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.
