Wiper system for motor vehicle windows, more particularly motor vehicle windscreens

The invention relates to a windshield wiper device () comprising a driving means () and a control unit () for the driving means (). An operating characteristic map () is provided, in which a maximum torque to be output by the driving means () and a minimum rotational speed of the driving means () are stored.

Windshield wiper device

The invention relates to a control device () for a drive unit () of a vehicle windshield wiper system () comprising at least one wiper arm (). The control device () is designed to determine a load quantity (L) of the drive unit () and to set the wiping frequency (WH) of the wiper arm () on the basis of the ratio of the load quantity (L) to at least one load threshold value (LS). Furthermore, the control device () is designed to set the wiping frequency (WH) depending on the current speed (v) of the vehicle.

Control device and control method for the drive unit of a windshield wiper system

The invention relates to a device and a method for actuating a wiper system. The device comprises a drive unit () for driving at least one wiper arm (), and a control unit (), wherein the control unit () is designed to set a wiping frequency of the wiper arm () as a function of a load variable which is dependent on the torque which is to be applied by the drive unit () during a wiping operation.

Device and method for actuating a drive unit of a wiper system

The invention relates to a bushing () for a drive unit, in particular an eccentric bushing () for a wiper drive of a windshield wiper, having an axial mounting section () and a radial flange section protruding therefrom, wherein the bushing () can be mounted having the mounting section () and having the flange section in/on a component, wherein the bushing () has a relief channel () such that a fluid can flow through the relief channel () upon mounting of the bushing () in/on the component and/or in a mounted state on/in the component. The invention furthermore relates to a drive unit, in particular a wiper drive for a windshield wiper of a motor vehicle, having a bushing () according to the invention.

Bushing for a drive unit and drive unit

A windshield wiper drive for a motor vehicle, with a reverse-operating driving motor for driving a wiper shaft which is connected in a rotationally fixed manner to a wiper arm, and with a fastening plate for fastening the windshield wiper drive to a vehicle body or to a component mounted on the body, wherein a first end stop surface for limiting the rotational movement of the wiper shaft in a first direction of rotation is provided on the fastening plate and/or on a component fixed to the fastening plate.

Windshield wiper drive

A system for determining if a tire of a vehicle is improperly inflated. The system includes a radar, a wheel speed sensor, and a controller. The radar is configured to emit a signal to detect a reflection of the signal off of an object positioned perpendicular to the vehicle, and to output an indication of a speed of the vehicle. The wheel speed sensor is configured to sense a speed of a wheel of the vehicle. The controller is configured to receive the indication of the speed of the vehicle from the radar, to calculate a speed of the vehicle based on the sensed speed of the wheel, and to determine a tire of the wheel is improperly inflated when the speed of the vehicle calculated using the wheel speed sensor varies by more than a predetermined amount from the speed of the vehicle determined using the radar signal.

Method for performing closed-loop and/or open-loop control of a windshield wiper device, computer program product, control device and windshield wiper device

The invention relates to a windshield wiper drive () for a motor vehicle, in particular a windshield wiper drive (), with a reverse-operating drive motor (), for driving a wiper shaft () connected non-rotatably to a wiper arm (), and with a fastening board () for attaching the windshield wiper drive () to a vehicle body or to a body-mounted component (). The invention provides that a first end stop surface () for delimiting the rotary movement of the wiper shaft () in a first direction of rotation is provided on the fastening board () or on a component () affixed to the fastening board ().

The invention relates to a pressure compensation device for compensating pressure between an inner chamber of a housing, in particular an electric motor, gearbox, container or the like and an outer side. The device includes a pressure compensation membrane mounted on an annular end face of a cylindrical structure that extends toward the outer side. The cylindrical structure is provided with a ventilation channel that extends therethrough. The cylindrical structure extends towards the outer side in order to form a projection from the wall of the housing, which projection is delimited by the end face on which the membrane is applied in a curved, dome-shaped form. A protective cover extends towards the outer side at a spaced apart distance in relation to the membrane over the cylindrical structure.

Pressure compensation element, in particular for pressure compensation in a housing

The invention relates to a wiper system with a wiper drive (), which is comprised of a wiper motor () and a gear (). A wiper arm shaft () for a wiper arm () can be driven via the output shaft () of the gear (). Linking points () for accommodating the wiper drive () on a surface () are arranged in the housing area () of the wiper drive (). The linking points () of the wiper drive () each feature a decoupling element (), in which fastening elements () to mount the wiper drive () either on a vehicle body () or on a screw-down surface () are accommodated.

Bearing for wiper drives

A wiper blade for cleaning motor vehicle windows has a wiper strip ( ) which is surrounded by a guard profile ( ) that with extensions ( ) formed onto its side cheeks ( ) engages longitudinal grooves ( ) of the wiper strip ( ) and is fixed axially on the wiper strip ( ) by inward-protruding protrusions ( ) in the region of its face ends ( ). The protrusions ( ) originate at one side cheek ( ) of the guard profile ( ), and a first protrusion ( ) extends on the outer face end ( ) of the guard profile ( ) to touch the opposite side cheek ( ) of the guard profile ( ), while a second protrusion ( ) on the inner face end ( ) forms a gap ( ) from the opposed side cheek ( ), which the gap allows mounting or unmounting of the guard profile ( ) in the longitudinal direction ( ).

Wiper blade

A windshield wiper has a wiper arm ( ), which is driven via a drive shaft and is made up of a fastening element ( ) and a hinge element ( ), pivotably connected to it via a swivel joint ( ). The hinge element has a wiper rod ( ) to which a wiper blade ( ) is pivotably connected, and at least one spray nozzle ( ) is disposed on a pivotable part ( ), the spray nozzle communicating with a water pump via a water line ( ). An electric resistance heating line ( ) in wire form is guided through the water line ( ) and has two insulated current-carrying leads ( ), which on one end are electrically connected to one another and on that end, with the spray nozzle ( ) of a heating-conducting material, form a contact point ( ) with good heat transfer.

Windshield wiper

The invention relates to a windshield wiper having arm ( ), which is driven via a drive shaft and on which a wiper blade is ( ) is pivotably connected. At least one spray nozzle ( ) for providing fluid to the windshield is disposed on one of the pivotable parts ( ) and is connected via a water inlet ( ) to a water pump. A nozzle body ( ) with one inlet conduit ( ) and at least one outlet conduit ( ) is provided in a housing ( ). A spray nozzle is mounted in the nozzle body. Both inlet and outlet conduits have openings on a jacket face of the nozzle body. A diaphragm ( ), in a pressureless state, closes the inlet conduit ( ) and the outlet conduit ( ) on the jacket face.
