Driving system of unmanned vehicle and driving path generation method
First Claim
1. A driving system of an unmanned vehicle, which generates a driving path for the unmanned vehicle and causes to travel the unmanned vehicle along the generated driving path to a target point, the system comprising:
- stopover point instructing means which instructs initial position information of a stopover point on a driving path and before a target point, the stopover point being a moving point which moves in position according to a position movement of the target point;
relative positional relationship information generating means which generates information on a relative positional relationship between the target point and the stopover point on the basis of the initial position information on the stopover point instructed by the stopover point instructing means and position information on the target point;
stopover point setting means which, when the position of the target point moves, sets a new stopover point at a position where the relative positional relationship can be maintained on the basis of position information on the position-moved target point, information on a direction of the unmanned vehicle at the position-moved target point, and the relative positional relationship information;
driving path generating means which, when the initial position of the stopover point is instructed by the stopover point instructing means, generates a driving path leading to the target point via the instructed stopover point on the basis of the initial position information on the stopover point and, when the position of the target point moves, generates a driving path leading to the position-moved target point via the new stopover point set by the stopover point setting means; and
driving control means which causes the unmanned vehicle to travel along the driving path to the target point via the stopover point on the basis of the information on the generated driving path.

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.

8. A driving path generation method for an unmanned vehicle, which generates a driving path leading to a target point of the unmanned vehicle, comprising:
-
instructing initial position information of a stopover point on a driving path and before a target point, the stopover point being a moving point which moves in position according to a position movement of the target point; when the initial position of the stopover point is instructed, generating a driving path leading to the target point via the instructed stopover point on the basis of the initial position information on the stopover point, and generating information on a relative positional relationship between the target point and the stopover point on the basis of the initial position information on the instructed stopover point and position information on the target point; and when the position of the target point moves, setting a new stopover point at a position where the relative positional relationship can be maintained on the basis of position information on the position-moved, target point, information on a direction of the unmanned vehicle at the position-moved target point, and the relative positional relationship information, and generating a driving path leading to the position-moved target point via the newly set stopover point.
