PURPOSE:To obtain a guidance controller for unmanned truck which can detect assuredly obstacles and stop automatically the drive of the truck together with simple attachment and simple change of a guide line, by detecting the horizontal shifts of front and rear parts of the truck body from the guide line with reception of a guiding light beam and separating a part of the light beam to an obstacle sensor. CONSTITUTION:A projector 10 is used for projection of a guiding light beam 100 and for setting a guide line AB. A guidance control part 20 of an unmanned truck 12 contains the 1st position shift sensors 22a and 22b and the 2nd position shift sensors 24c and 24d. The projecting position of the beam 100 is detected based on the detection outputs of those 1st and 2nd sensors. Thus the truck 12 can be driven accurately with control along the line AB which is indicated by the beam 100. If an obstacle exists in the traveling direction of the truck 12, the beam 100 is cut by the obstacle. Thus an obstacle sensor 28a and 28b detects the obstacle, and the drive of the truck 12 is stopped automatically. |
