The invention concerns a rear view system (1) of a motor vehicle comprising:—an optical image capturing sensor (3),—a protective support (5) comprising a transparent and flat protective screen (7), the optical sensor (3) being installed on the protective support (5) in such a way as to point through said protective screen (7), and—a scraper blade (9) for cleaning the protective screen (7) disposed on the face of the protective screen (7) opposite that of the optical sensor (3) side, characterised in that it further comprises an electromagnetic actuation device (11) for actuating said scraper blade (9) in translation on the protective screen (7).

A cleaning device for a surface, such as a windshield of a vehicle, includes an active positioning system and a cleaning head. The active positioning system is configured to deploy from a storage position hidden from view within a covered storage space and to position the cleaning head upon the windshield. The active positioning system includes a first extension member and a second extension member that move relative to one another to position the cleaning head, and also move the cleaning head across the windshield along a path. The cleaning head can have a brush portion configured to agitate debris from the window, and a drying portion configured to dry the window after cleaning. The cleaning device can be controlled via a touch-screen display in the vehicle, enabling a user to direct that specific portions of the windshield be cleaned as desired.

A wiper device for a small and curved surface such as a spherical surface of an optical element includes at least one elongate wiper element with two ends, two drive units to which the ends of the wiper element are attached so that the wiper element can be moved on the surface of the optical element using the two drive units, and at least one contacting means for bringing the wiper element into contact with a surface of the optical element, the contacting means shapes the wiper element around at least that part of the surface which is exposed to the environment due to an opening provided by the housing and is to be cleaned.

A windshield wiper system (100) includes a pivoting wiper arm (110); a wiper blade (120) for wiping a surface (102); and a connector assembly (128) coupling the pivoting wiper arm (110) to the wiper blade (120), the connector assembly (128) comprising a gear drive (130) including at least one drive gear (132) and at least one positioning cog (136), wherein the gear drive (130) rotates the wiper blade (120) based on an angular position of the pivoting wiper arm (110) such that an arc of a motion path (320) of the wiper blade (120) is reduced.

A vehicle wiper system includes a plurality of first sensor elements, an adjustable wiper, and a second sensor. The plurality of first sensor elements is configured to be disposed at a periphery of a vehicle window to form a boundary. The adjustable wiper has a distal end and a proximal end, and an adjustment mechanism that enables a distance between the distal end and the proximal end to change. The adjustable wiper is configured to travel along a windshield to define a wiper path. The second sensor element is disposed adjacent the distal end, and is configured to operate in conjunction with the first sensor element to adjust the adjustable wiper such that a distance between the distal end and the proximal end changes, and a distance between the distal end of the wiper and the boundary remains substantially consistent as the adjustable wiper travels along the wiper path.

A contaminant removal apparatus for windshields includes: driving belts located at both side surfaces of a windshield; a drive unit configured to apply driving force to the driving belts; a wiper assembly located on the windshield; rotary rollers configured to be shifted along the driving belts; idle gears located at ends of the driving belts to change a rotating direction of the rotary rollers; frame connection shafts coupled to both ends of the wiper assembly and located within the rotary rollers so as to contact the idle gears to change the rotating direction of the rotary rollers; and a controller configured to change a rotating direction of the rotary rollers when the idle gears and the frame connection shafts contact.

A windshield wiper system for use on an aircraft includes a controller and a wiper assembly including a wiper arm, a wiper blade, and a moving block. Further, the windshield wiper system includes a rail assembly including a rail assembly rack, a plurality of electromagnets, and an electrical interface. The electrical interface and the plurality of electromagnets induce a force on the moving block of the wiper assembly, causing the wiper assembly to sweep across the windshield of the aircraft. The controller is coupled to the rail assembly and the controller is configured to direct the motion of the wiper assembly through command signals to the rail assembly.

A camera cleaning system for an autonomous vehicle may include a platform that can accommodate multiple cameras, wiper systems, as well as a fluid delivery system. The wiper system may include a wiper, rail, and a hydraulic motion component for each camera. The platform surface that contacts the wiper system's wipers and cleaning fluid may be angled and may include a window or lens for each camera. The autonomous vehicle may include a controller that may decide when a camera cleaning protocol should be executed. Alternatively, or additionally, a camera cleaning protocol may be executed periodically, as indicated by a controller.

An autonomous vehicle includes a front bumper comprising an opening; a light detection and ranging (LiDAR) sensor comprising a surface exposed to the opening of the front bumper; and a sensor cleaning device configured to remove foreign materials on the surface. The sensor cleaning device includes a wiper configured to move over a surface of a sensor to remove foreign materials from the surface of the sensor; and a movement unit connected to the wiper and comprising at least a linkage system configured to perform folding and unfolding movements, which causes the wiper to reciprocate over the surface of the sensor.

The invention relates to a motor vehicle driver assistance system (100) comprising at least one detection module (101) and a cleaning device (120), the detection module (101) comprising at least one driver assistance sensor (110, 130) and at least a protective window (140) closing the detection module (101) and protecting the at least one driver assistance sensor (110, 130), the cleaning device (120) being configured to clean the protective window (140) and the cleaning device (120) comprising at least one wiper (121) in contact with the protective window (140) and able to move in a rectilinear main direction (D).
