A cleaning unit for cleaning foreign matter from a cover, in particular a cover of a transmitter/receiver window of an environment sensor, including at least one movable wiper blade, which is arranged so as to wipe off foreign matter such as water or dirt on the cover by movement along the cover. For this purpose, the wiper blade touches the cover for example with one or multiple rubber lips. The wiper blade is positioned in an inclined manner with respect to a direction of movement of the wiper blade and is thus movable in such a way that a force exerted by the moved wiper blade on the foreign matter has a component in the direction of the force of gravity. Also described is a related device for sensing the environment as well as a method for cleaning a cover.

A motor-powered windshield scourer for any type of a motor-powered vehicle and or motor craft. The motorized windshield scourer may have a motor propelled appendages or a singular appendage that have replaceable scouring attachments joined to the appendages. The motor that propels the appendages can be positioned anywhere on or in the motor vehicle/craft, whether under the hood, in the cabin or elsewhere. The motor driven appendages with joined scouring attachments may be mounted on the windshield of the vehicle directly opposite of the windshield wiper blades. When turned on, the motor may move the appendages with joined attachments in a side to side and/or up and down motion across the windshield. The appendages may include an unpliable metal such as: steel, titanium, tungsten, or inconel, and the scouring attachments may include nylon scouring pads or a vinyl coated mesh attached to and covering rubber or foam.

A vehicle wiper device includes a first driving lever, a second driving lever, a first driven lever, a second driven lever, a first wiper arm, a first wiper blade, a second wiper arm, and a second wiper blade. The first driving lever is pivoted by a driving force of a first drive source. The second driving lever is pivoted by a driving force of a second drive source. A pivoting speed of the second wiper blade from a lower reversal position is set to be greater than a pivoting speed of the first wiper blade from a lower reversal position.

A wiper device includes a wiper arm that includes a recess and that is swung due to rotation of a wiper motor, the wiper arm causes a wiper blade coupled to a leading end portion of the wiper arm to perform a wiping operation across a surface of a windshield glass, an acceleration sensor that is installed in the recess of the wiper arm, a drive circuit that generates a voltage to be applied to the wiper motor, and a control circuit that controls the drive circuit such that a voltage to reduce a change in acceleration of the wiper arm, detected by the acceleration sensor, is applied to the wiper motor.

The invention relates to a geared motor (1) for a wiper system of a motor vehicle, comprising a brushless direct-current electric motor (2) comprising: a rotor (20) comprising magnetic elements (29); a stator (21) comprising coils for the electromagnetic excitation of the rotor; a rotating shaft (22) secured to the rotor; a reducing mechanism (3) connecting the rotating shaft (22) and an output shaft (8) of the geared motor; and a housing (4) forming a protective envelope for the electric motor (2) and said reducing mechanism (3). According to the invention, a bearing (23) guides the rotating shaft (22) on one of the longitudinal ends of the rotating shaft, said bearing (23) being arranged inside the rotor (20) and stator (21) assembly and housed in a recess inside the rotor (20), the envelope of the housing (4) comprising an inwardly projecting part (40) penetrating said inner recess and carrying a seat (41) for said bearing (23).
