GUIDANCE DEVICE FOR UNMANNED TRAVELLING VEHICLE

摘要

PURPOSE: A guidance system of an unmanned driving working vehicle is provided to guide a working vehicle to be suitable for a charger by using an electric motor electrified from a battery and a turbine. CONSTITUTION: An unmanned driving working vehicle (10) comprises an electric motor and a turbine. The electric motor is mounted on a vehicle and is electrified from a battery (30). The turbine is mounted inside a vehicle. The turbine operates a vehicle wheel (14). A working machine inside the vehicle is operated when the turbine drives on a work area (70) using the electric motor. The magnetic field intensity of an area wire (72) is detected to a magnetic sensor arranged in a vehicle body and returns to a charger arranged on the area wire. The area wire is offset to a right or left direction and guides a working vehicle to rotate in the offset direction and restore to a straight posture when the working vehicle is connected to the charger.
