Abstract
An unmanned vehicle management system includes: an inter-vehicle distance determination unit that determines an inter-vehicle distance between a sprinkling vehicle and an unmanned vehicle traveling behind the sprinkling vehicle in a same direction as that of the sprinkling vehicle based on a sprinkling state from a sprinkling spray provided in the sprinkling vehicle traveling in a work site; and an output unit that outputs, to the unmanned vehicle, inter-vehicle distance data indicating the inter-vehicle distance determined by the inter-vehicle distance determination unit.
Claims17
An unmanned vehicle management method in a work site where a sprinkling vehicle configured to travel and sprinkle from a sprinkling spray provided in the sprinkling vehicle, and an unmanned vehicle configured to travel behind the sprinkling vehicle in a same direction as that of the sprinkling vehicle;
- comprising:
- calculating an inter-vehicle distance between the sprinkling vehicle and the unmanned vehicle to be longer than a distance calculated by adding a braking distance of the unmanned vehicle to a distance that sprinkling by the sprinkling spray reaches based on a sprinkling state from a sprinkling spray;
- outputting inter-vehicle distance data indicating the inter-vehicle distance to the unmanned vehicle to set the inter-vehicle distance, and
- controlling the unmanned vehicle according to the calculated inter-vehicle distance between the sprinkling vehicle and the unmanned vehicle.
An unmanned vehicle management system comprising:
- a sprinkling vehicle configured to travel and sprinkle in a work site from a sprinkling spray provided in the sprinkling vehicle;
- an unmanned vehicle configured to travel behind the sprinkling vehicle in a same direction as that of the sprinkling vehicle, and a processor as a processing circuit configured to:
- calculate an inter-vehicle distance between a sprinkling vehicle and an unmanned vehicle based on a sprinkling state from the sprinkling spray, wherein the inter-vehicle distance is calculated to be longer than a distance obtained by adding a braking distance of the unmanned vehicle to a distance that sprinkling by the sprinkling spray reaches;
- output, to the unmanned vehicle, inter-vehicle distance data indicating the calculated inter-vehicle-distance to set the inter-vehicle distance;
- and
- control the unmanned vehicle according to the calculated inter-vehicle distance between the sprinkling vehicle and the unmanned vehicle.
