Abstract: A work vehicle automated travel system for executing automated travel of a work vehicle along a travel route comprising work routes, in which work is performed by a work unit, and turning routes. Said work vehicle automated travel system is provided with an operation unit. Said operation unit is able to select implementation or non-implementation of an automated work unit control, which detects the beginning of turning of the work vehicle and automatically raises the work unit and disconnects the work clutch of the work unit, and detects completion of the turning of the work unit and automatically lowers the work unit and connects the work clutch. If the beginning of turning is detected while the work vehicle is performing automated travel in a turning route, automated work unit control is implemented regardless of whether implementation or non-implementation of automated work unit control has been selected by the operation unit.

Abstract: This autonomous travel system for a work vehicle is provided with an autonomous travel control unit. The autonomous travel control unit is capable of using a positioning system to cause a work vehicle to travel autonomously along a travel path including a turning path and a work path in which work is performed by a work unit. The work vehicle is provided with a vehicle speed control unit for controlling the vehicle speed and a vehicle speed operation unit for manipulating the vehicle speed. The vehicle speed control unit is capable of executing vehicle speed maintenance control in which even when operating force applied to the vehicle speed operation unit is released, the vehicle speed of the work vehicle corresponding to the operating position of the vehicle speed operation unit prior to release is maintained.
