Work vehicle vicinity monitoring system and work vehicle

Abstract

The controller (100) of this work vehicle vicinity monitoring system comprises: an overhead image synthesis unit (110) that generates overhead image information for displaying an overhead image of a work vehicle and the vicinity thereof on a display device; a display control unit (140) that displays, on the same screen of a monitor (50), a first image in which a mark indicating a target object detected by radar devices (21-28) is superimposed on the overhead image and a second image captured by imaging devices (11-16); a warning issuing unit (150) that issues, as a warning, a first warning in which an area where a mark is present is differentiated from areas where a mark is not present within the first image and / or a second warning in which a sound is issued to indicate the presence of a target object; and a warning cancellation unit (160) that, on the basis of a warning cancellation signal from a warning cancellation switch (53), cancels warnings in accordance with a cancellation order based on positions where a target object is present.

Description

technical field [0001] The present invention relates to techniques for monitoring the periphery of a work vehicle. Background technique [0002] Various work vehicles, such as dump trucks and hydraulic excavators, operate at civil engineering work sites or quarry sites of mines. Especially in mines, very large work vehicles are used. Compared with ordinary vehicles, such a work vehicle has a larger width, height, and front-to-rear length, so it is difficult for an operator to confirm and grasp the surrounding conditions through a rearview mirror or the like. A device for monitoring the surroundings of a vehicle has been proposed as a technique for allowing an operator to easily grasp the surrounding conditions of a vehicle and perform driving support. For example, a device is disclosed that presents the danger level of an obstacle within the operating position range of a working machine (Patent Document 1).
