PROBLEM TO BE SOLVED: To enable a vehicle detection sensor using a light emitter and receiver to appropriately detect a vehicle by distinguishing from an obstacle.SOLUTION: A control device for vehicle detection comprises: a receiving part for receiving a detection signal from a vehicle detection sensor equipped with a plurality of light emitters and receivers; and a light-shielding cause determination part for starting light-shielding cause determination processing when it detects according to the detection signal the occurrence of at least one long-period light-shielding region with a period when the light is shielded exceeding the first threshold. The light-shielding cause determination part outputs vehicle determination information indicating the presence of a vehicle when the light is shielded in both of two light emitters and receivers adjacent to both sides of the long-period light-shielding region, among the plurality of light emitters and receivers. |
