Abstract
A control system includes: a detector detecting a position of a work machine running on a running path; a non-contact sensor detecting an object at a side of the running path; a generator generating map data of a work site based on detection data from the detector and the non-contact sensor; a first storage storing past map data generated in the generator based on the detection data from the detector and the non-contact sensor acquired in a predetermined period in a past; a second storage storing current map data generated in the generator based on the detection data from the detector and the non-contact sensor; a first calculator calculating integrated map data by integrating the past map data and the current map data; and a second calculator by matching the integrated map data and the detection data from the non-contact sensor, calculates the position of the work machine.
