PURPOSE:To eliminate an irregular working track at a place near the end of a route by giving the prescribed control to the conversion of direction of an automatic driving truck which performs work to the ground with reciprocating drives. CONSTITUTION:A truck 1 moves forward by a prescribed distance l2 and has the first 90 deg. turn l3 after a copying sensor A detects the end of a working route. Then the truck 1 peforms the 2nd 90 deg. turn l4 and at the same time moves forward by a prescribed distance l5. During this advance, the direction of the truck 1 is corrected by a steering operation so that the detecting direction of a direction sensor 6 is coincident with the prescribed reference direction. Then the truck 1 is moved parallel with a steering operation during it travles a prescribed distance l6 after the sensor A detects an unprocessed work area B. Then the left position of the truck 1 is corrected. In such a way, an irregular working track is eliminated at a place near the end of the working route by controlling the direction conversion of the truck 1. |
