Abstract: A vehicle cleaning system includes a drive pump, an ejection nozzle and a valve device. The valve device includes an intake passage, a valve that closes the intake passage and accumulates pressure of the fluid supplied to the intake passage, a discharge passage, and an auxiliary mechanism. The auxiliary mechanism generates leakage of the fluid from the intake passage during the pressure accumulation to accumulate pressure with the leakage at a leaked side, opens the valve body based on two pressures accumulated in the intake passage and the leaked side, outputs the fluid, which is pressure-accumulated in the intake passage, to the discharge passage by opening the valve body, and closes the valve body as the fluid is output to the discharge passage to allow for re-accumulation of the pressure in the intake passage.

Abstract: A cleaning target provided to a vehicle is automatically cleaned in an appropriate manner. A vehicle cleaning system includes a cleaning section configured to clean a cleaning target provided to a vehicle, and a control section configured to control cleaning of the cleaning target by the cleaning section according to at least one out of a travel situation of the vehicle, an environmental situation of the vehicle, or an indicator relating to adhesion of adhered material to the cleaning target of the vehicle.

Abstract: A vehicle washing device, including: a wiping section configured to wipe a predetermined range on a windshield of a vehicle, the predetermined range including an imaging range of an imaging section configured to image an exterior of the vehicle through the windshield from inside a vehicle cabin; and a spraying section provided outside the vehicle cabin and configured to spray a washer liquid onto the windshield, the spraying section having a spray direction of the washer liquid configured such that a spray region of the washer liquid interposed between a pair of tangents, each extending from the spraying section and tangential to a landing region at which the sprayed washer liquid lands on the windshield, has an overlap with the imaging range of no greater than a predetermined proportion of the imaging range, or such that the spray region is separated from a predetermined region of the imaging range.

Abstract: A valve device includes a washing inlet, outlets, a switching inlet, a movable switching member, and a conversion engagement portion. The outlets is configured to be in communication with the washing inlet. The movable switching member is movable in a linear direction based on a pressure of a fluid that is fed to the switching inlet. The conversion engagement portion converts linear movement of the movable switching member into a rotation of a predetermined angle.
