Abstract
A foreign substance detection system includes: a vehicle provided with a detector that detects a foreign substance present on a road on which the vehicle travels; and a server device that determines whether or not the foreign substance actually exists on the road on which the vehicle travels based on a detection result of the detector. Further, the server device evaluates validity of the detection result of the foreign substance by comparing, between a plurality of vehicles, the detection result of the foreign substance by the detector and information on a position where the foreign substance has been detected.
