A wiper drive device includes: a drive member that is configured to cause a wiper blade to wipe a region of a windshield as a wiping operation, the region of the windshield including a to-be-imaged region of the windshield, the to-be-imaged region being included in a field of view of a camera which images a predefined imaging range near a vehicle through the windshield; and a stop section that is configured to stop the wiper blade in an outside region in response to that an anomaly that hinders the wiping operation occurs while the drive member causes the wiper blade to perform the wiping operation on the windshield, the outside region being a region of the windshield outside of the to-be-imaged region.

A work vehicle comprising: a cab, an inside of which is a cockpit, having a window portion; a vehicle body having a passage on a periphery of the cab; a front lateral wiper provided so as to be rotatable around a first axis and along the window portion, and rotating around a second axis that extends in a different direction with the first axis in a movement range between a normal position that is in contact with the window portion and a rising position separated from the window portion; and a passage fence extending along an outer edge of the passage. The passage fence is configured to open upward with penetrating the passage fence inwardly and outwardly, and a part of the passage fence has an opening that includes the movement range of the front lateral wiper.

A cab of a work vehicle includes a front windshield that extends in a vehicle width direction; front lateral windshields that extends diagonally rearward and is connected to both sides of the front windshield in the vehicle width direction via ridgelines, and a rear-end edge of each front lateral windshield extending in a vertical direction being gradually separated from the ridgeline of each front lateral windshield while extending downward; a front lateral wiper that is disposed so as to be rotatable around an upper axis that is disposed above each front lateral windshield and so as to be rotatable along each front lateral windshield; an upper drive device that is configured to reciprocally rotate the front lateral wiper around the upper axis between a rear position in and a front position.

A windshield wiper installation system is configured to be used to install a wiper on a windshield of an aircraft. The windshield wiper installation system includes a housing, an installation control unit contained within the housing, at least one positioning member secured to the housing, wherein the installation control unit is operatively coupled to the positioning member(s), and at least one position-setting member secured to the housing, wherein the installation control unit is operatively coupled to the position-setting member(s). The positioning member(s) is configured to be engaged to move the wiper to one or more desired positions on the windshield. The position-setting member is configured to set the desired position(s) when the wiper is at the desired position(s).

A windshield assembly includes a laminated windshield provided with a cutout and a motor mounting plate secured to the laminated windshield over the cutout. The motor mounting plate includes a first mounting area. An exterior motor cover plate is secured on an exterior side of the laminated windshield and overlays the cutout in facing relation with the motor mounting plate. The exterior motor cover includes a second mounting area in alignment with the first mounting area. The structure distributes forces encountered by the wiper and motor over a large area on the glass. Also, due to a small footprint, the view through the windshield is less obstructed. The structure also eliminates the need for drilling/aligning holes in laminated glass.

A wiper system performs operation control on wiper driving electric motors and based on position information about wiper blades and attached to pivot shafts, wherein a learning mode in which a position of the wiper blades is learned to correct blade position information is executed after the wiper blades are attached to the pivot shafts, respectively. In the learning mode, the wiper blades are moved to a prescribed position such as a lower retracted position, and that the wiper blades are located in the prescribed position is detected by such means as a sensor, a video image, and contact with a jig. If the wiper blades are detected to be in the prescribed position, the blade position information is corrected to a value corresponding to the position.

A wiper system for a machine is provided. The wiper system includes a first motor configured to operate a first wiper and a second motor configured to operate a second wiper wherein the first motor and the second motor are connected in a parallel configuration. The wiper system further includes a power source which is in electrical connection with the first and the second motors for energizing each motor to move the respective wipers. The wiper system includes a switch configured to simultaneously operate the first motor and the second motor in one of a high speed mode, a low speed mode, or a park mode. The wiper system includes an isolating circuit configured to isolate the first motor from the power source and allow the second motor to run independent of the first motor when the switch is set in the park mode and speed of the first motor is different from speed of the second motor.

A vehicular wiper device is provided with a snowfall determination unit that determines whether a predetermined snowfall condition is satisfied. When the snowfall determination unit determines that a predetermined snowfall condition is satisfied, a controller that controls a wiper motor changes lower reverse positions of wiper blades to lower reverse positions during snowfall that are on the lower side with respect to lower reverse positions during normal times.

A wiper arrangement for a vehicle is configured for cleaning a sensor field of vision of a windshield and thereby has a wiping element and a carrier. The carrier can be fastened on the windshield. The wiping element is movably mounted on the carrier. The carrier, the wiping element and/or mounting elements acting between the carrier and the wiping element is/are configured so that the wiping element can assume at least one fixed holding position-relative to the carrier, and wherein the wiping element can be brought out of the fixed holding position at least by overcoming a defined holding force. Furthermore, the mounting of the wiping element on the carrier is selected such that the wiping element is always driven to assume at least one specific, preferably a first holding position or second specific holding position with respect to the carrier.

A control apparatus that can be mounted on a vehicle which includes an observation apparatus for observing a peripheral environment and a performance recovering apparatus for recovering a performance of the observation apparatus, comprising a predicting unit configured to predict, based on driving information of the vehicle, a degree of performance degradation of the observation apparatus while the vehicle is traveling, and a determination unit configured to determine execution of a driving operation of the performance recovering apparatus based on a prediction result by the predicting unit.
