In a vehicle wiper apparatus, rotation of an output shaft of a wiper motor is converted to reciprocal rotation of a pivot shaft, and a wiper member, attached to the pivot shaft, reciprocally rotates between closed and open positions. A nozzle, provided in the wiper member, sprays a cleaning fluid towards a front side in an advancing direction of the wiper member on at least one of forward and return paths of the reciprocal rotation. A washer pump supplies the cleaning fluid to the nozzle. A round-trip time of the wiper member is detected based on a detection result of a detecting unit that detects at least a state in which the wiper member is positioned in the closed position. The washer pump is controlled based on a detected round-trip time, and is operated during rotation of the wiper member on at least one of the forward and return paths.

A cleaning target provided to a vehicle is automatically cleaned in an appropriate manner. A vehicle cleaning system includes a cleaning section configured to clean a cleaning target provided to a vehicle, and a control section configured to control cleaning of the cleaning target by the cleaning section according to at least one out of a travel situation of the vehicle, an environmental situation of the vehicle, or an indicator relating to adhesion of adhered material to the cleaning target of the vehicle.

The invention relates to a device (1) for de-icing and/or cleaning insects off a vehicle window (10) which is designed to perform at least a window wiping function and comprising a continuous-rotation motor (40) designed to drive the rotation of at least one wiper (30) to at least a first level corresponding to a first wiping speed, referred to as high wiping speed (HWS), and a second level at a second wiping speed, referred to as low wiping speed (LWS) and lower than the first, so as to perform the wiping function, and a system for spraying a specific, de-icing or insect-cleaning liquid, onto the window (10) from the said at least one wiper (30), characterized in that the continuous-rotation motor is designed in such a way as to operate at a third speed (CS), lower than the second speed, and in that the device is configured to cause the said wiper (30) to at least descend from the high position (PH) as far as the low position (PB) with the motor (40) operating at the very slow speed (CS) and with the said spraying system activated over at least part of the said descent. The invention also relates to the continuous-rotation motor suited to the device and to a cleaning method using the device.

A system includes a dome, a wiper assembly, a position sensor and a control device. The wiper assembly includes a wiper blade configured to rotate around the dome. The position sensor may be configured to send a signal to a control device when a wiper blade passes the position sensor. The control device may include one or more processors configured to receive the signal from the position sensor and determine a location of the wiper blade relative to the dome based on the received signal.

A vehicle cleaning device removes an extraneous object collected on a cleaning subject of a vehicle. The vehicle cleaning device includes: a cleaning liquid supply device mounted on the vehicle; and a wiper device including a wiper driver and a wiper blade. The wiper driver includes a linear movement portion that produces a linear movement based on supply of a cleaning liquid that is pressure-fed from the cleaning liquid supply device, and a movement converter that converts the linear movement into a pivoting movement. The wiper blade is arranged to be contactable with the cleaning subject. The wiper device is configured to cause the wiper blade to perform a reciprocal wiping operation based on the pivoting movement of the movement converter.

The present invention relates to a motor vehicle's windscreen wiper, that includes a wiper blade and driving system; where the driving system includes a wiper motor, a wheel plate that pivots about a central rotational axis; where the wheel plate's angular position is associated with the wiper blade's angular position; where a parking cam on the wheel is associated with two parking contact springs with parking electrodes that press against the wheel plate surface under a resilient bias of the parking contact spring; where a parking trace is defined by a track slid by the parking electrode on the wheel plate during the wheel plate's rotation such that distances between the contact spring parking electrodes and the wheel plate's central rotation axis is substantially equal to each other such that traces of the parking electrodes generally coincide with each other; where the invention further includes a single-trace parking cam consisting of only one arc-segment such that the parking trace substantially follows a center arc by; where application of the single-trace cam is able to achieve the wiper parking function of the windscreen wiper in a compact and cost-effective manner.

A washer fluid distribution device includes a plurality of nozzle units formed consecutively, a transfer conduit configured to pass through the plurality of nozzle units and having one end fluidly connected to an introduction part, the introduction part located at one end of the transfer conduit and configured to allow a washer fluid to be introduced from a washer pump, a plurality of discharge holes configured to correspond to the number of the nozzle units in the transfer conduit and having different angles based on a center of the transfer conduit, and a controller configured to control a rotation angle of the transfer conduit to allow the discharge holes to correspond to the nozzle units in response to a user’s request.

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.

Work machines, control systems for work machines, and methods of operating work machines are disclosed herein. A work machine includes a frame structure, a work implement, a camera, a cleaning system, and a control system. The work implement is coupled to the frame structure and includes at least one ground engagement tool configured for interaction with an underlying surface in use of the work machine. The camera is coupled to the frame structure and configured to provide camera input indicative of one or more images captured by the camera in use of the work machine. The cleaning system is coupled to the frame structure and configured to clean the camera in use of the work machine. The control system is coupled to the frame structure and includes a controller communicatively coupled to the camera and the cleaning system.

A system includes a dome, a wiper assembly, a position sensor and a control device. The wiper assembly includes a wiper blade configured to rotate around the dome. The position sensor may be configured to send a signal to a control device when a wiper blade passes the position sensor. The control device may include one or more processors configured to receive the signal from the position sensor and determine a location of the wiper blade relative to the dome based on the received signal.
