PROBLEM TO BE SOLVED: To provide a control device of an autonomous working vehicle capable of accurately detecting the position of a working vehicle without using an expensive position detection sensor.SOLUTION: A control device 31 of an autonomous working vehicle includes: a route generation unit 313 for generating a travel route along the borderline of a working region, on the basis of the turn angle detected by a turn angle detection unit and the travel distance detected by a travel distance detection unit during trace mode; a storage unit 314 for storing the magnetic field intensity detected by one magnetic sensor during the trace mode in association with the travel route; a position specification unit 315 for specifying the position of the working vehicle during work mode, on the basis of a comparison result between the magnetic field intensity detected by one magnetic sensor and the stored magnetic field intensity.SELECTED DRAWING: Figure 6 |
