Abstract

A work vehicle periphery monitoring system (10) is a system which monitors a periphery of a work vehicle with a vessel for loading a load thereon and includes: a plurality of radar devices (21 to 28) each of which is attached to the work vehicle and detects an object existing around the work vehicle and a controller (100) which notifies an alarm based on detection results of the radar devices (21 to 28) and switches between a notification mode for notifying the alarm and a restriction mode for stopping the notification of the alarm based on a state of the work vehicle.

Claims

1. A work vehicle periphery monitoring system which monitors a periphery of a work vehicle with a vessel for loading a load thereon, the work vehicle periphery monitoring system comprising:

a plurality of object detecting devices each of which is attached to the work vehicle and detects an object existing around the work vehicle; and

a controller which notifies an alarm when the object detecting device detects the object around the work vehicle and switches a notification mode for notifying the alarm and to a restriction mode for restricting the notification of the alarm when the load is loaded on the vessel.

4. The work vehicle periphery monitoring system according to claim 1,

wherein the controller stops the notification of the alarm using at least a sound in the restriction mode.

5. The work vehicle periphery monitoring system according to claim 4,

wherein the controller displays an alarm image on a display device.

6. The work vehicle periphery monitoring system according to claim 1,

wherein the controller stops an operation of the object detecting device to set the restriction mode.

7. The work vehicle periphery monitoring system according to claim 1,

wherein the controller causes the detection result of the object detecting device not to be input to set the restriction mode.

8. The work vehicle periphery monitoring system according to claim 1,

wherein the controller sets the restriction mode when receiving a loading start signal transmitted from a loading machine which loads the load on the vessel, and

wherein the controller sets the notification mode when receiving a loading end signal transmitted from the loading machine.

9. The work vehicle periphery monitoring system according to claim 1,

wherein the work vehicle includes a position detecting device,

wherein the controller includes a storage unit which stores position information of a loading station, and

wherein the controller sets the restriction mode when a current position detected by the position detecting device is equal to a position indicated by the position information stored in the storage unit.

10. The work vehicle periphery monitoring system according to claim 1,

wherein the controller switches the restriction mode to the notification mode when a brake of the work vehicle is released in the restriction mode.

2. (canceled)

3. The work vehicle periphery monitoring system according to claim 2,

wherein the controller sets the restriction mode when a brake of the work vehicle is operated.

11. A work vehicle periphery monitoring system which monitors a periphery of a work vehicle with a vessel for loading a load thereon, the work vehicle periphery monitoring system comprising:

a plurality of object detecting devices each of which is attached to the work vehicle and detects an object existing around the work vehicle; and

a controller which notifies an alarm when the object detecting device detects the object around the work vehicle and switches a notification mode for notifying the alarm to a restriction mode for stopping at least the notification of the alarm using a sound when the load is loaded on the vessel.

12. A work vehicle comprising:

a work vehicle periphery monitoring system which monitors a periphery of a work vehicle with a vessel for loading a load thereon, the work vehicle periphery monitoring system comprising;

a plurality of object detecting devices each of which is attached to the work vehicle and detects an object existing around the work vehicle; and

a controller which notifies an alarm when the object detecting device detects the object around the work vehicle and switches a notification mode for notifying the alarm and to a restriction mode for restricting the notification of the alarm when the load is loaded on the vessel.
