Abstract

A parallel operation work vehicle for enabling operation of an autonomous work vehicle by a long distance operating device installed in an accompanying work vehicle for performing work while accompanying the autonomous work vehicle, wherein the accompanying work vehicle is provided with a display and a speaker as notification means, the notification means is capable of communicating with the autonomous work vehicle through a communication device, and, when a distance to the edge of the cultivated field from the autonomous work vehicle approaches a set distance, a control device transmits a signal to a control device of the accompanying work vehicle through the communication device and issues a warning through the notification means.

Claims

1. A traveling system of work vehicles wherein

in an autonomous traveling work vehicle including position calculation means for positioning a machine body, utilizing a satellite positioning system, and a control device that causes the autonomous traveling work vehicle to automatically travel and work along a set traveling route, and an accompanying traveling work vehicle that enables the autonomous traveling work vehicle to be operated with a remote operation device mounted on the accompanying traveling work vehicle that performs work while traveling, accompanying the autonomous traveling work vehicle,

the accompanying traveling work vehicle is provided with notification means, the notification means can communicate with the autonomous traveling work vehicle through a communication device, and when a distance of the autonomous traveling work vehicle to a field end becomes close to a set distance, a control device makes warning notification with the notification means through the communication device.

3. The traveling system of work vehicles according to claim 1, wherein the notification means displays the notification on a display, and makes the notification by voice from a speaker.

4. The traveling system of work vehicles according to claim 1, wherein the control device of the accompanying traveling work vehicle is connected to the communication device, and is also connected to speed change means to decrease a speed when a warning is issued.

2. A traveling system of work vehicles wherein

in an autonomous traveling work vehicle including position calculation means for positioning a machine body, utilizing a satellite positioning system, and a control device that causes the autonomous traveling work vehicle to automatically travel and work along a set traveling route, and an accompanying traveling work vehicle that enables the autonomous traveling work vehicle to be operated with a remote operation device mounted on the accompanying traveling work vehicle that performs work while traveling, accompanying the autonomous traveling work vehicle,

the accompanying traveling work vehicle is provided with notification means, the notification means can communicate with the autonomous traveling work vehicle through a communication device, and when it becomes before a set time that the autonomous traveling work vehicle reaches a field end, a control device makes warning notification with the notification means through the communication device.

8. The traveling system of work vehicles according to claim 2, wherein the notification means displays the notification on a display, and makes the notification by voice from a speaker.

9. The traveling system of work vehicles according to claim 2, wherein the control device of the accompanying traveling work vehicle is connected to the communication device, and is also connected to speed change means to decrease a speed when a warning is issued.

5. A traveling system of work vehicles, wherein
