Abstract
External sensors of a vehicle are individually set with sensing regions through external surfaces. Cleaning nozzles of the vehicle inject cleaning fluid to individually clean the external surfaces of the external sensors. An injection control unit performs classification of the cleaning nozzles, which correspond to the external surfaces whose sensing regions of the external sensors overlap with each other, into an injected nozzle, which performs injection of cleaning fluid and a stopped nozzle, which stops injection of cleaning fluid, and controls the classification according to a stain state of the external surface. A priority control unit controls a priority of cleaned sensor data, which is acquired through the external sensor whose external surface corresponds to the injected nozzle, to be lower than a priority of non-cleaned sensor data, which is acquired through the external sensor whose external surface corresponds to the stopped nozzle.
