CONTROL SYSTEM FOR WORK MACHINE, WORK MACHINE, MANAGEMENT SYSTEM FOR WORK MACHINE, AND CONTROL METHOD AND PROGRAM FOR WORK MACHINE

摘要

A control system 30 for a work machine is provided with: a GPS receiver 31 that detects the GPS position of a dump truck; a laser sensor 24B that detects the positions of objects in the vicinity of the dump truck; and a position measurement controller 33 that, when the dump truck is traveling along a travel route, detects, from the detection results of the GPS receiver 31 and the detection results of the laser sensor 24B, the position of an upward protrusion that protrudes upward from the surface of the travel route, and stores, in a database 36 for map storage, the detected position of the upward protrusion as map information for the travel route. The position measurement controller 33 determines whether the state of the dump truck reduces the precision of map information. When it is determined that the state of the dump truck does not reduce the precision of map information, the storage of map information for the travel route continues. When it is determined that the state of the dump truck reduces the precision of map information, the storage of map information for the travel route is halted.
