A wiper device is provided. An operating range of each of two sets of wiper arm units can be properly restricted. A first wiper arm unit is prevented from colliding with a first front pillar or a dash panel when a first output shaft of a first speed reduction mechanism has rotated beyond a first control angle, and a second wiper arm unit is prevented from colliding with a second front pillar or the dash panel when a second output shaft of a second speed reduction mechanism has rotated beyond a second control angle.

A windshield wiper system (WWS) is provided. The WWS includes a brushless direct current (BLDC) motor, a wiper arm and blade, a gearbox/converter operably interposed between the BLDC motor and the wiper arm and blade and a smart motor drive configured to determine a WWS failure condition and to operate the BLDC motor according to the determination.

Embodiments provide vehicle camera cleaning systems used for cleaning foreign matter off of a camera lens, including, for example, a water flow nozzle arranged to eject water flow, an air nozzle arranged to eject air, and a central controller used to control the water flow nozzle and air nozzle. In certain embodiments, a plurality of sensing devices are used for sensing the conditions of the camera lens, such as an infrared water drop sensor, a temperature sensor, a camera sensing sensor, and the like. The central controller may determine whether there are water drops, ice, snow, or other foreign matter on the lens based on signals received from the plurality of sensing devices, and may control the air nozzle and the water flow nozzle to clean the camera lens based on the foreign matter present.

A cleaning tool is adapted for cleaning a camera lens or sensor of a vehicle comprising a surface being subject to weather conditions in which coarse matter adheres to the surface. The cleaning tool comprises a body comprising a container for containing a cleaning solution, a delivery nozzle fluidly connected to the container, and a trigger for forcing the cleaning solution through the delivery nozzle to be sprayed over the surface of the sensor. The cleaning tool further comprises a blade extending from the body, the blade comprising an operating edge for sliding against the surface to remove the coarse matter from the surface, and a swabbing component housed by the body, the swabbing component being made from microfiber, chamois or an alternative type of cleaning cloth material and being adapted for polishing the surface.

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 system for a motor vehicle according to an exemplary aspect of the present disclosure includes, among other things, a controller and a rear wiper configured to wipe a rear window of the motor vehicle in response to instructions from the controller. Further, the controller is configured to instruct the rear wiper to run at a predefined speed for a predefined time period based on a plurality of factors. A method is also disclosed.

A windshield-wiper system includes a precipitation-detector, a windshield-wiper actuator, an object-detector, and a controller. The precipitation-detector detects precipitation proximate to a host-vehicle. The windshield-wiper actuator clears the precipitation from a windshield of the host-vehicle. The object-detector detects a distance of an object to the host-vehicle. The controller is in communication with the precipitation-detector, the windshield-wiper actuator, and the object-detector. The controller determines when the precipitation is present based on the precipitation-detector, determines the distance from the object to the host-vehicle based on the object-detector, and adjusts a speed of the windshield-wiper actuator when the precipitation is detected and the object is less than a distance-threshold away from the host-vehicle.

A rain sensor system for measuring a quantity of rain on a window of a vehicle is provided. The rain sensor system comprises a camera device configured to capture images of an area surrounding the vehicle using camera optics; and a rain sensor including a transmitter and a receiver, the transmitter being configured to emit or transmit light and the receiver being configured to receive measurement light that is emitted or transmitted by the transmitter and guided to the receiver by the window. The transmitter and the receiver are arranged at a distance (d) from each another, and the receiver and the camera optics of the camera device are different components.

A system includes a computer including a processor and a memory, the memory storing instructions executable by the processor to actuate a windshield wiper on a vehicle, collect amplitude data and frequency data from a sound of the windshield wiper, and, upon determining that the amplitude data meets a first predetermined threshold and the frequency data meets a second predetermined threshold, actuate a vehicle component to move the vehicle to a specified location.

A display device, particularly for an exterior mirror of a motor vehicle, comprising a display means that comprises a lighting means, characterized in that the display device comprises a moisture detection apparatus comprising a sensor device, the moisture detection apparatus being designed to at least partially detect light emitted by the display means and light reflected by moisture.
