A control system 30 for a work machine is provided with: a GPS receiver 31 that uses GPS to detect the GPS position of a dump truck; a determination unit that determines whether the error in the detected GPS position exceeds a prescribed error; a laser sensor 24B that detects the positions of objects in the vicinity of the dump truck; and a database 36 for map storage, in which, if the determination unit determines that the error in the GPS position of the dump truck detected by the GPS receiver 31 does not exceed the prescribed error, a detection result regarding an upward protrusion that protrudes upward is extracted from the detection results of the laser sensor 24B, and the extracted detection result regarding the upward protrusion is stored as map information. |
