Abstract

A control system is provided with a position detection device which detects a position of a work machine, a contactless sensor which detects an object around the work machine in a contactless manner, a position calculation unit which calculates a position of the work machine on the basis of at least map data indicating a position of the object and detection data of the contactless sensor, and a diagnosis unit which compares the position of the work machine derived from detection data of the position detection device and the position of the work machine calculated by the position calculation unit and diagnoses that there is an abnormality in either the detection data of the position detection device or a calculation result of the position calculation unit.
