Autonomous travel working vehicle
In order to adjust the sensitivity of an obstacle detection means and improve detection accuracy when an obstacle is actually present although the obstacle detection means detects no obstacle or when no obstacle is actually present although the obstacle detection means detects an obstacle, an autonomous travel working vehicle is provided with a position calculation means for measuring the position of a vehicle body using a satellite positioning system, and a control device for automatic travel and work along a set travel path. The autonomous travel working vehicle is provided with an obstacle sensor, an alarm means, and a false report switch, and if, although an obstacle has been detected and an alarm has been issued, an operator does not recognize the obstacle and activates the erroneous report switch, the control device cancels the alarm.
1. An autonomously traveling work vehicle comprising:
a position calculation means positioning a position of a vehicle body by using a satellite positioning system; and
a control device making the vehicle travel and work automatically along a set traveling route,
characterized in that
an obstacle detection means, an alarm means and a false notification means are provided, and when an operator does not recognizes an obstacle and the false notification means is operated though the obstacle is detected and an alarm is given, the control device cancels the alarm.
2. The autonomously traveling work vehicle according to claim 1 , wherein when number of false notification made by the false notification means reaches a first set value, the control device reduces sensitivity of the obstacle detection means.
3. The autonomously traveling work vehicle according to claim 1 , wherein after reducing the sensitivity of the obstacle detection means, when the number of false notification made by the false notification means reaches a second set value, the control device judges as sensor breakage and displays and notifies the breakage.
4. An autonomously traveling work vehicle comprising:
a position calculation means positioning a position of a vehicle body by using a satellite positioning system; and
a control device making the vehicle travel and work automatically along a set traveling route,
characterized in that
an obstacle detection means, an alarm means and a notification failure notification means are provided, and at a time at which any alarm is not given though an obstacle exists in a detection range of the obstacle detection means, when an operator operates the notification failure notification means, the control device gives an alarm.
5. The autonomously traveling work vehicle according to claim 4 , wherein when the obstacle detection means does not detect any obstacle and sudden braking is performed, the control device judges as notification failure.
6. The autonomously traveling work vehicle according to claim 4 , wherein when notification of the notification failure reaches a third set number, the control device raises sensor sensitivity.
7. The autonomously traveling work vehicle according to claim 4 , wherein after raising the sensitivity of the obstacle detection means, when a notification failure notification number reaches a fourth set number, the control device judges as breakage and displays and notifies the breakage.
