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.

A vehicle cleaning system is provided including a foreign object detection section configured to detect a foreign object present on a windshield, a foreign object removal device configured to clean the windshield to remove the foreign object, an actuation notification section configured to notify a user of actuation of the foreign object removal device, and a control section that, when the foreign object detection section has detected the foreign object, controls the actuation notification section so as to notify of actuation of the foreign object removal device before controlling the foreign object removal device so as to clean the windshield.

A windshield wiper system includes a windshield wiper having a wiper blade with a near end and a far end. The windshield wiper is configured for performing a relative rotation of the wiper blade between the far end and the near end of the wiper blade. A mechanism applying a torque to the far end during a sweeping motion of the windshield wiper twists the far end of the wiper blade relative to the near end. The mechanism may perform the relative rotation of the wiper blade regardless of whether the wiper blade is in contact with a windshield. For example, the mechanism may include a stationary cam block having a cam profile, and an actuator arm moving along the cam profile with the sweeping motion of the windshield wiper. The cam profile is suitably shaped to pivot the actuator arm in laterally outer ranges of the sweeping motion.

Window wiping device for a motor vehicle comprising at least one link (2, 3), a mobile arm (6) adapted to be mounted on the vehicle by said link (2, 3) and effect an angular to-and-fro movement (A), a flexible washing liquid feed tube (16), rigidly fastened to said mobile arm (6), which device is characterized in that it further comprises a means (20) for limitation of a curvature assumed by said flexible feed tube (16) configured to surround the flexible feed tube (16) so as to prevent it cracking.

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 present invention comprises an AS-side wiper motor 40 including an AS-side output shaft 83 that is rotated in forward and backward directions and a link mechanism 60 constituted by a four-bar link. The AS-side wiper member 50 is configured to wipe in a first AS-side wipe range 11b by a pivotal movement of the AS-side output shaft 83 in a first angular range SA1, and wipe in a second AS-side wipe range 11c by a pivotal movement of the AS-side output shaft 83 in a second angular range SA2 that differs from the first angular range SA1. The wipe range of the AS-side wiper member 50 can thus be switched between the first AS-side wipe range 11b and the second AS-side wipe range 11c by controlling an angular range, in which the AS-side output shaft 83 is pivotally moved, to be in the first angular range SA1 or the second angular range SA2 that differ from each other. In addition, a size of the wipe range can be adjusted by controlling a pivot angle of the AS-side output shaft 83 in forward and backward directions.

A vehicular wiper device includes a first wiper arm, a first drive source, a rocking mechanism, a second drive source, an extension and retraction mechanism, and a control unit. A first wiper blade for wiping a surface to be wiped of a vehicle is connected to the front end of the first wiper arm. The first drive source is directly or indirectly affixed to the vehicle body. The rocking mechanism is driven by the drive force of the first drive source and reciprocates and rocks the first wiper arm. The second drive source is directly or indirectly affixed to the vehicle body separately from the first drive source. The extension and retraction mechanism is driven by the drive force of the second drive source and extends and retracts the first wiper arm in the longitudinal direction thereof. The control unit controls the drive of the first drive source and the second drive source so that the extension and retraction operation of the first wiper arm performed by the extension and retraction mechanism will correspond to the rocking operation of the first wiper arm performed by the rocking mechanism.

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.

Casing (20) for a windscreen wiper drive rod, in particular of a motor vehicle, said casing being configured to cover at least a portion of said drive rod and comprising means for fixing to said drive rod and/or to at least one element (42) linked to said drive rod, characterised in that it further comprises support and guiding means (70) which are configured to cooperate with at least one electric cable (63) and/or at least one fluid line (64) of said windscreen wiper.
