An onboard system for winterizing vessels includes an antifreeze storage system. The onboard system includes a control system capable of determining one or more of the one or more system components to be winterized, an antifreeze storage system, and one or more pumps capable of pumping antifreeze from the antifreeze storage system. The antifreeze flows through the determined one or more system components to be winterized.

This technology relates to system for clearing a sensor cover. The system may include a sprayer, a support, and a positioning device. The sprayer may be mounted to the support and direct a flow of fluid to the sensor cover. The positioning device may be configured to adjust the position of the sprayer on the support. The system may include a nozzle and the nozzle may be positioned to direct the flow of fluid to an area of the sensor cover. The system may include additional sprayers.

A cleaning device for selectively bombarding a surface with a media sequence, the sequence including at least a first gaseous medium and a second liquid medium, includes a nozzle configured to bombard the surface with the second medium; a cleaning valve with a holding port, a pressure port, a plunger, and a pressure outlet; and a high-pressure accumulator configured to store the first medium. The first medium is loaded with an accumulator pressure. The cleaning device further includes a changeover valve configured to selectively create a connection between a first medium supply line and a holding line connected to the holding port. The pressure outlet is configured to bombard the surface with the first medium in pulse-like fashion.

A device for dispensing liquid onto a target area of a vehicle surface is described, and includes a mixing valve that is in communication with a pressurized fluidic supply system via a fluidic distribution system, and a controller. The mixing valve includes an outlet orifice that is disposed proximal to the target area, and the mixing valve includes first and second valve conduits that are fluidly connected to the outlet orifice via a mixing portion. The first valve conduit includes a first control valve, and the second valve conduit includes a second control valve. The fluidic distribution system includes a first fluidic conduit and a second fluidic conduit. The controller is operatively connected to the fluidic supply system, and the first and second control valves.

A vehicle surface cleaning device comprising a vehicle integrated housing including a nozzle carrier extendable from and retractable into the bodywork of a vehicle, said nozzle carrier being provided with at least one fluid nozzle, and comprising means for contactlessly heating the fluid nozzle while being in a retracted position.

The disclosure relates to a method for operating a cleaning system for cleaning a sensor surface of a sensor of a vehicle, in particular an optical sensor, having the step: applying an amount of compressed air to the sensor surface in an air cleaning step characterized by: checking an air cleaning result in a checking step; in the event of a negative air cleaning result, performing a hybrid cleaning step including: applying an amount of cleaning fluid to the sensor surface in a fluid, in particular liquid, cleaning step; and/or, applying an amount of compressed air to the sensor surface in a further air cleaning step.

A composite nozzle comprises: a housing having formed at one side thereof a cleaning liquid inlet through which the cleaning liquid is introduced, an installation port communicating with the cleaning liquid inlet at the other side thereof, and an air inlet path communicating with an air inlet on the outer side of the installation port; an opening and closing valve installed so as to be slidably movable toward one side and the other side in the installation port formed in the housing; an elastic body such as a spring that slidably moves the opening and closing valve while elastically supporting the opening and closing valve; and a cap which sprays the cleaning liquid to the outside from the other end of the housing in which the opening and closing valve is installed so as to be slidably movable in one direction and the other direction of the installation port.

A method of preventing washer fluid freezing is provided. The method includes performing hose residual washer fluid removal control that removes residual washer fluid of a hose which is a movement path of washer fluid after a spray of the washer fluid by operation of a pump washer fluid device.

A vehicle cleaning device removes an extraneous object collected on a cleaning subject of a vehicle. The vehicle cleaning device includes: a cleaning liquid supply device mounted on the vehicle; and a wiper device including a wiper driver and a wiper blade. The wiper driver includes a linear movement portion that produces a linear movement based on supply of a cleaning liquid that is pressure-fed from the cleaning liquid supply device, and a movement converter that converts the linear movement into a pivoting movement. The wiper blade is arranged to be contactable with the cleaning subject. The wiper device is configured to cause the wiper blade to perform a reciprocal wiping operation based on the pivoting movement of the movement converter.
