Abstract
An automatic guided vehicle detects marks located on a plurality of points along a route it travels using at least three sensors, selects the number of marks detected from each individual sensor as a reference value in accordance with the logic of majority, and stops when the reference value agrees with a predetermined value. Cumulative errors, caused by misdetection are thus avoided and, there is little cumulative error. Thus, accurate control in long distance travel is possible.
