Route generation method, device, and program for a work vehicle operating in a narrow area
A route generation method executes generating a plurality of work routes where a work vehicle travels straight in a first direction that is a travel direction of the work vehicle, in a work area where a crop is arranged, generating a movement route that is a route continuous with the work route and that includes a straight route where the work vehicle travels straight, in a headland area adjacent to the work area in the first direction, in non-work areas surrounding the work area, where the crop is not arranged, and generating a movement route that is a single route continuous with the movement route and that guides the work vehicle to each of the plurality of work routes.
1. An autonomous travel system for a route generation comprising:
a work vehicle having an autonomous traveling controller, mounted on the work vehicle, executing and traveling on a plurality of work routes where the work vehicle travels straight in a first direction that is a travel direction of the work vehicle, in a work area where a work object is arranged;
wherein
the work vehicle having the controller, executes and travels on a first movement route that is a route continuous with at least one of the plurality of work routes and that includes a straight route, in a first non-work area adjacent to the work area in the first direction, in non-work areas surrounding the work area, where the work object is not arranged; and
the work vehicle having the controller, executes and travels on a second movement route that is a single route continuous with the first movement route and that guides the work vehicle to each of the plurality of work routes.
2. The autonomous travel system for a route generation according to claim 1 , wherein the second movement route includes a straight route where the work vehicle travels straight in a second direction that is a direction opposite to the first direction.
3. The autonomous travel system for a route generation according to claim 1 , wherein the second movement route is included in a second non-work area adjacent to the work area in a direction orthogonal to the first direction, in the non-work areas.
4. The autonomous travel system for a route generation according to claim 1 , wherein the second movement route is a work route located at an end of the work area in the plurality of work routes.
5. The autonomous travel system for a route generation according to claim 1 , wherein the straight route included in the first movement route extends in a direction inclined with respect to the first direction.
6. The autonomous travel system for a route generation according to claim 1 , wherein a turning radius of a turning route included in the first movement route is set to a smaller value than a turning radius of a turning route included in the second movement route.
7. The autonomous travel system for a route generation according to claim 6 , wherein a user operation to select a turning radius of a turning route is accepted, and the turning radius of the turning route included in the first movement route and the turning radius of the turning route included in the second movement route are set on a basis of the user operation.
8. The autonomous travel system for a route generation according to claim 1 , wherein a travel speed of the work vehicle traveling on the second movement route is set to a speed according to a length of the second movement route.
9. The autonomous travel system for a route generation according to claim 1 , wherein the work vehicle is a vehicle that can perform a spraying work in which a sprayed object is sprayed on a first work object and a second work object in each of the right-left directions of the first work object while traveling over the first work object.
10. An autonomous travel system for a route generation comprising:
a work vehicle; and
an operation terminal having a route generation processor that generates in an autonomous traveling controller, mounted on the work vehicle,
wherein
the work vehicle travels on a plurality of work straight in a first direction that is a travel direction of the work vehicle, in a work area where a work object is arranged;
the work vehicle travels on a first movement route that is a route continuous with at least one of the plurality of work routes and that includes a straight route, in a first non-work area adjacent to the work area in the first direction, in non-work areas surrounding the work area, where the work object is not arranged; and
the work vehicle travels on a second movement route that is a single route continuous with the first movement route and that guides the work vehicle to each of the plurality of work routes.
11. An autonomous travel system comprising:
a work vehicle; and
an operation terminal containing a route generation program for causing one or more processors in an autonomous traveling controller, mounted on the work vehicle, to execute wherein:
the work vehicle with the controller, executes and travels on a plurality of work routes straight in a first direction that is a travel direction of the work vehicle, in a work area where a work object is arranged;
the work vehicle with the controller, executes and travels on a first movement route that is a route continuous with at least one of the plurality of work routes and that includes a straight route where the work vehicle travels straight, in a first non-work area adjacent to the work area in the first direction, in non-work areas surrounding the work area, where the work object is not arranged; and
the work vehicle with the controller, executes and travels on a second movement route that is a single route continuous with the first movement route and that guides the work vehicle to each of the plurality of work routes.
