Abstract

This automated travel system for spraying work has a target path generation unit for generating a target path for a spraying work. A work vehicle is provided with left and right liquid spraying units which have spraying patterns including: a four-direction spraying pattern in which each of the left and right liquid spraying units sprays a liquid to both the left and right directions; and a direction-restricted spraying pattern in which the number of spraying directions of the left and right liquid spraying units is restricted to 3 or less. The target path generation unit generates the target path P in a path setting to incorporate a four-direction spraying path for which the four-direction spraying pattern is set as a spraying pattern and direction-restricted spraying paths for which the direction-restricted spraying pattern is set as a spraying pattern.

Claims (12)

1. A route generation method, comprising:

generating a target route including a plurality of work routes corresponding to each row of a plurality of work objects and multiple movement routes connecting the plurality of work routes; and

controlling a work vehicle to travel automatically in a field in which the plurality of work objects disposed in the target route are arranged in multiple rows.

2. The route generation method according to claim 1 , wherein the plurality of work routes are set with a travel order in which the work vehicle travels automatically, and the multiple movement routes connect the plurality of work routes to the travel order of the work vehicle.

3. The route generation method according to claim 1 , wherein

the plurality of work routes are routes along which the work vehicle travels automatically while performing work, and the multiple movement routes are routes along which the work vehicle travels automatically without performing work.

4. A route generation method comprising:

generating a target route including a plurality of work routes for every other row or every several rows of multiple rows of work objects, and multiple movement routes connecting the plurality of work routes; and

controlling a work vehicle to travel automatically in a field in which the work objects disposed in the target route are arranged in the multiple rows.

5. A route generation method comprising:

generating a target route including a plurality of work routes in a field in which a plurality of work objects are arranged in multiple rows, and multiple movement routes connecting the plurality of work routes; and

controlling a work vehicle to travel automatically in a field across odd-numbered rows or even-numbered rows of the multiple rows of the work objects disposed in the target route.
