Management system for work vehicle and management method for work vehicle

1. A management system for a transport vehicle, comprising:

at least one processor configured to:

generate entering route data that causes a transport vehicle including a dump body to enter with forward movement, through a route from an entrance of a loading place to a loading point of the loading place, and exiting route data that causes the transport vehicle to exit with backward movement, through a route from the loading point to an exit of the loading place, a load being discharged from a rear portion of the dump body, and the loading point indicating a position where a loading operation is performed by a loading machine; and

output the entering route data and the exiting route data to the transport vehicle,

wherein the at least one processor is further configured to:

calculate an entering traveling area indicating an area passed through by the transport vehicle that travels on the entering route, based on the entering route data and an outer shape of the transport vehicle;

calculate an exiting traveling area indicating an area passed through by the transport vehicle that travels on the exiting route, based on the exiting route data and the outer shape data of the transport vehicle;

calculate an overlapping area between the entering traveling area and the exiting traveling area; and

correct the entering route data and the exiting route data such that, when a first transport vehicle is present in the overlapping area, a second transport vehicle having entered from the entrance waits at a standby point outside the overlapping area, and when the first transport vehicle exits from the overlapping area, the second transport vehicle waiting at the standby point starts moving.

2. The management system for a work vehicle according to claim 1 ,

wherein the transport vehicle has an obstacle sensor at each of a front portion and a rear portion, and is configured to detect an obstacle at the time of forward movement and at the time of backward movement.

3. The management system for a work vehicle according to claim 1 ,

wherein the at least one processor is configured to correct the entering route data and the exiting route data of the first transport vehicle and the entering route data and the exiting route data of the second transport vehicle such that a sum of a time until the first transport vehicle exits the overlapping area after finishing work at the work point and a time until the second transport vehicle moves from the standby point to the work point becomes small.

4. The management system for a work vehicle according to claim 1 ,

wherein the at least one processor is configured to correct the entering route data and the exiting route data such that the overlapping area becomes small.

5. A management method for a transport vehicle, comprising:

generating entering route data that causes a transport vehicle including a dump body to enter with forward movement, through a route from an entrance of a loading place to a loading point of the loading place, and exiting route data that causes the transport vehicle to exit with backward movement, through a route from the loading point to an exit of the loading place, a load being discharged from a rear portion of the dump body, and the loading point indicating a position where a loading operation is performed by a loading machine; and

outputting the entering route data and the exiting route data to the transport vehicle,

wherein the method further comprises:

calculating an entering traveling area indicating an area passed through by the transport vehicle that travels on the entering route, based on the entering route data and an outer shape of the transport vehicle;

calculating an exiting traveling area indicating an area passed through by the transport vehicle that travels on the exiting route, based on the exiting route data and the outer shape data of the transport vehicle;

calculating an overlapping area between the entering traveling area and the exiting traveling area; and

correcting the entering route data and the exiting route data such that, when a first transport vehicle is present in the overlapping area, a second transport vehicle having entered from the entrance waits at a standby point outside the overlapping area, and when the first transport vehicle exits from the overlapping area, the second transport vehicle waiting at the standby point starts moving.
