A method for indirectly deriving a systematic dependence for a system behavior of a system component of a cleaning system of a motor vehicle. The cleaning system is adapted for cleaning at least one surface of the motor vehicle by means of a cleaning process adapted for a resource efficient cleaning. Additionally, a diagnosing method, a method for selecting a resolution strategy, a use of a resolution strategy, a cleaning method, a cleaning system, and a motor vehicle are disclosed.

Described herein are sensor assembly cleaning apparatuses and methods of operation thereof that utilize a fluid such as pressurized air to cause dispersion of debris, rain droplets/water droplets from other sources, condensation, or any other environmental contaminant that may obscure a transparent surface such as a glass window of a camera housing from the glass window. In this manner, the pressurized air acts to clean the transparent surface, and as a result, improve the clarity of the field-of-view provided through that transparent surface to a camera housed in the camera housing. In addition, sensor assembly cleaning apparatuses described herein can include a water nozzle that is adapted to eject high pressure water onto the transparent surface as well as towards an air nozzle or an air vent that is adapted to eject the pressurized air. The water nozzle can thus be used to remove debris form the air nozzle.

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.

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 sensor system to be mounted on a vehicle includes a LiDAR, a camera, a housing that accommodates the LiDAR and the camera and a cleaner that is attached to the housing and has at least one nozzle configured to clean a first cleaning target surface corresponding to the LiDAR and a second cleaning target surface corresponding to the camera at the same time using a cleaning medium.

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.

A system for distributing washer liquid includes at least one washer pump connected to a reservoir to pressurize the washer liquid, at least one distributor including at least one distribution unit fluidly connected to the washer pump, a plurality of nozzles fluidly connected to the at least one distribution unit in a distributor among the at least one distributor to face a cleaning target, and a controller configured to control opening or closing of the distribution unit formed in the at least one distribution unit and to control pressure of the washer pump.

A method for indirectly deriving a systematic dependence for a system behavior of a cleaning system of a motor vehicle. The method relates to a system behavior of a cleaning process of a surface of the motor vehicle, for cleaning of at least one surface of the motor vehicle. The method relates to a resource efficient cleaning and/or a resource-saving cleaning. Moreover, the method relates to a cleaning method, a use of a systematic dependence, a cleaning system and a motor vehicle.
