Document Type and Number:
WIPO Patent Application WO/2020/039782
Kind Code:
A1
Abstract:
In the present invention, work efficiency is improved by increasing the vehicle speed of a work vehicle in a work area within a work field while the work area is widened. This automatic traveling system for a work vehicle has a vehicle speed control unit (42), a storage unit (47) for storing a target path, and an automatic traveling control unit (46) for causing a work vehicle (1) to perform automatic traveling according to the target path by use of a satellite positioning system. The target path includes a plurality of parallel paths arranged in parallel in a traveling area in a field and a plurality of turning paths for connecting, in a traveling order, the plurality of parallel paths in an outer edge part of the traveling area. The automatic traveling control unit (46) has a separation distance measurement unit (46A) that, when the work vehicle is performing automatic traveling on a parallel path, measures a separation distance, in the work vehicle advancing direction, from the work vehicle to the outer peripheral edge of the work field. The vehicle speed control unit (42) has a vehicle speed limitation unit (42A) that limits the vehicle speed of the work vehicle in accordance with the separation distance.
