Abstract: An onboard optical sensor cleaning device ejects fluid against a sensing surface of an onboard optical sensor installed in a vehicle and removes foreign matter from the sensing surface. The onboard optical sensor cleaning device includes a cleaning liquid ejection port that ejects supplied cleaning liquid and an air ejection port that ejects supplied air. The cleaning liquid ejection port and the air ejection port are independent from each other, an air ejection axis of the air ejection port is set so that the ejected air mixes with the cleaning liquid ejected from the cleaning liquid ejection port and to be directed toward the sensing surface.

Abstract: The on-vehicle optical sensor cleaning system includes a washer pump that feeds a cleaning liquid, an air pump, a nozzle member, and a controller. The air pump includes a discharge valve and discharges air through the discharge valve. The discharge valve opens when air is compressed in the air pump. The nozzle member includes an ejection port that ejects a gas-liquid mixture toward a sensing surface of an on-vehicle optical sensor to remove foreign matter from the sensing surface. The cleaning liquid from the washer pump and the air from the air pump are mixed in the gas-liquid mixture. The controller controls the washer pump and the air pump. The controller is configured so that the gas-liquid mixture is ejected by storing the cleaning liquid in the nozzle member to cover the ejection port and then feeding the air to the nozzle member.
