Abstract

A working vehicle perimeter monitoring system includes: a plurality of object detecting devices which are attached to a working vehicle and detect an object existing in a periphery of the working vehicle; and a controller which enables or disables of a generation of an alarm notifying an existence of the object based on a detection value of the object detecting device and a predetermined threshold value and sets the predetermined threshold value to be different inside and outside a predetermined region set in the periphery of the working vehicle based on an operation range of the working vehicle.

First claim

1 . A working vehicle perimeter monitoring system comprising:
a plurality of object detecting devices which are attached to a working vehicle and detect an object existing in a periphery of the working vehicle; and a controller which enables or disables of a generation of an alarm notifying an existence of the object based on a detection value of the object detecting device and a predetermined threshold value and sets the predetermined threshold value to be different inside and outside a predetermined region set in the periphery of the working vehicle based on an operation range of the working vehicle, wherein the predetermined region is set based on at least a trace of a front corner portion of the working vehicle when the working vehicle turns at a minimum turning radius.

2 . (canceled)

3 . The working vehicle perimeter monitoring system according to claim 1 ,
wherein the controller generates the alarm when at least the detection value is equal to or larger than the predetermined threshold value, and the predetermined threshold value inside the predetermined region is smaller than the predetermined threshold value outside the predetermined region.

4 . The working vehicle perimeter monitoring system according to claim 1 ,
wherein the predetermined region has a rectangular shape in a plan view.

5 . The working vehicle perimeter monitoring system according to claim 4 ,
wherein the predetermined region has a rectangular shape in the plan view in at least one of a front side and a lateral side of the working vehicle or in both sides thereof.

6 . A working vehicle perimeter monitoring system comprising:
a plurality of object detecting devices which are attached to a working vehicle and detect an object existing in a periphery of the working vehicle by a radar; and a controller which generates an alarm at least when a detection value of the object detecting device is equal to or larger than a predetermined threshold value, wherein a predetermined region is set in a periphery of the working vehicle based on at least a minimum turning radius of the working vehicle and a trace of a front corner portion of the working vehicle and the predetermined threshold value inside the predetermined region is smaller than the predetermined threshold value outside the predetermined region.

7 . A working vehicle comprising:
the working vehicle perimeter monitoring system according to claim 1 .
