Patent ID: 8280573

Claim:
A guided travel control device for an unmanned vehicle, said guided travel control device comprising: a remote control tower for guiding and causing the unmanned vehicle to travel along a target travel course, said target travel course being line-shaped and said vehicle traveling at a vehicle speed according to a target speed with a guidance error in a width direction of the vehicle occurring according to the vehicle speed, the target travel course being set between right and left travelable borderlines which are predetermined so that the borderlines show boundaries of a travel passage width in the width direction of the unmanned vehicle, the travel passage width being a width in which the unmanned vehicle is capable of traveling to right side or left side with respect to a traveling direction of the unmanned vehicle target speed setting means for setting the target speed of the unmanned vehicle such that when the unmanned vehicle is guided and caused to travel along the target travel course, the target speed increases as a distance in the width direction of the unmanned vehicle between a current target point on the target travel course and the right or left travelable borderline increases, and the target speed decreases as a distance in the width direction of the unmanned vehicle between a current point of the unmanned vehicle and the right or left travelable borderline decreases; and guided travel control means for guiding and causing the unmanned vehicle to travel along the target travel course so that the set target speed can be obtained.
