Guidance system of unmanned work vehicle

摘要

PROBLEM TO BE SOLVED: To provide a guide device for an unmanned traveling working vehicle arranged to appropriately guide the unmanned traveling working vehicle to a charger when the unmanned traveling working vehicle returns to the charger for battery charging in the unmanned traveling working vehicle arranged to drive a working machine by an electric motor that is mounted on a vehicle body and is supplied with power from a battery and to cause the working machine to operate.;SOLUTION: An unmanned traveling working vehicle 10 is provided with an electric motor and other electric motors supplied with power from a battery and is arranged to drive a working machine by the electric motor to operate while driving wheels by the other electric motors and traveling in a working area defined by an area wire. The unmanned traveling working vehicle 10 is further arranged to travel while detecting magnetic field intensity of the area wire by left and right magnetic sensors 34 and to return to a charger 84 disposed on the area wire for battery charging. The area wire having a first offset portion 72a1 and a second offset portion 72a2 is offset in one of left and right directions as viewed in a plan view. Accordingly, a guide device for the unmanned traveling working vehicle guides the unmanned traveling working vehicle such that the unmanned traveling working vehicle turns from a straight-traveling position to an off-set direction and subsequently returns to the straight-traveling position when the unmanned traveling working vehicle travels to be connected to the charger 84.;COPYRIGHT: (C)2013,JPO&INPIT
