A cleaning device for cleaning a lens of a motor vehicle camera using a cleaning head, which includes hydraulic drive members that drive the camera or the cleaning head. The hydraulic drive members are able to generate a relative longitudinal displacement of the cleaning head with respect to the camera between a passive position in which the cleaning head is positioned outside of the image-capturing field of the camera and an active position in which the cleaning head extends facing the lens so as to allow cleaning liquid to be ejected towards the lens. The hydraulic drive members include a chamber in which a piston secured to the camera or to the cleaning head slides under the effect of the pressure of a liquid circulating between a first orifice and a second orifice which are formed respectively in the chamber.

An electric pump includes a cylinder, a piston, a motor, and a discharge valve. The cylinder includes a valve port and a discharge port, which is in communication with the valve port. The discharge valve opens and closes the valve port. When the piston is moved forth to narrow a void in the cylinder, air is compressed in the cylinder. The discharge valve opens when operated by the piston that moves forth. The discharge valve opens and discharges compressed air from the valve port so that fluid including air is discharged from the discharge port.

A camera device for a motor vehicle includes a camera module with a module body having at least one aperture, a sensor adapted to detect electromagnetic radiation of a spectral range and arranged within the module body, and an optical element mounted to substantially cover, fill or close the aperture, a deployment system adapted to move the camera module between a retracted state, in which at least the optical element is arranged within the cavity of the vehicle body with the outer surface of the camera module body being generally flush with the exterior of the vehicle body, and a deployed state, in which the camera sensor is operable and at least the optical element protrudes from the vehicle body, and cleaning means for cleaning the optical element at least during movement of the camera module between the retracted state and the deployed state.

An apparatus includes a base, a cylindrical sensor window fixed to the base, and a helical cleaning member movable between a retracted position in the base and an extended position extending around the sensor window. The cleaning member includes an outlet directed at the sensor window when the cleaning member is in the extended position.

A cleaning device, intended to spray at least one fluid towards a surface to be cleaned of a motor vehicle, such as an optical sensor of an optical detection system, comprises at least one fluid intake and distribution device (D) into which are selectively admitted a cleaning fluid and a drying fluid through two distinct sets of runs from an intake end-fitting (110, 111) specific to each fluid. According to the invention, a blocking element (5) is provided in the intake and distribution device (D). This blocking element is movable between a first position of blocking of the set of runs for a cleaning fluid and a second position of clearing of this set of runs for a cleaning fluid.

The present invention concerns a device (1) for cleaning an optical sensor (3), in particular intended to equip a motor vehicle, comprising a nozzle (5) for dispensing a cleaning liquid, characterised in that the cleaning liquid dispensing nozzle (5) is a drip dispensing nozzle and is configured to deposit the cleaning liquid on the optical sensor (3) in individual drops.

A vehicle and a method of controlling the vehicle capable of removing contamination of a Light Detection and Ranging (LiDAR) surface mounted on the vehicle are provided. The vehicle may include: Light Detection and Ranging (LiDAR) configured to detect an object and a terrain around the vehicle; and a cleaning nozzle device configured to inject cleaning liquid and compressed air to a passage of laser pulses on a LiDAR surface.

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 a surface, such as a windshield of a vehicle, has a housing that holds a spray bar, rotatable brush and a wiper blade. An engagement mechanism moves spray bar, the brush, and the wiper blade out from a disengaged position within the housing to an engaged position outside the housing so that they can be used to clean, brush, and dry the surface. After the spray bar, brush, and wiper blade are used to, respectively, clean, brush, and dry the surface, the engagement mechanism then moves the spray bar, the brush, and the wiper blade to a disengaged position within the housing.

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.
