  • Patent number: 9037338
    Abstract: Based on initial position information on an instructed fixed switch-back point and position information on a loading point, a relative positional relationship between the loading point and the switch-back point is generated. If the position of the loading point moves, then based on position information on the position-moved loading point, information on a direction of an unmanned vehicle at the loading point and information on a relative positional relationship, a new switch-back point is set at a position where the relative positional relationship can be maintained. When the initial position of the switch-back point is instructed, then on the basis of the initial position information on the switch-back point, a driving path leading to the loading point via the instructed switch-back point is generated and, when the position of the loading point moves, a driving path leading to the position-moved loading point via the new switch-back point is generated.

  • Patent number: 9008889
    Abstract: Topographical data for a work location is created and information on a new travel route is generated. Next, a work location including the new travel route is constructed on the basis of the created topographical data. Then, the information on the new travel route generated is provided to the vehicle, the vehicle is made to travel along said new travel route in accordance with temporary travel control data, and actual topographical data for the new travel route is acquired. Next, the aforementioned temporary travel control data is corrected on the basis of the acquired actual topographical data for the new travel route. After that, the unmanned vehicle is made to travel in accordance with the corrected travel control data.
