Abstract: A raindrop detection device includes: a front monitoring camera for photographing a front of a vehicle through a windshield of the vehicle; a raindrop detection camera for photographing a raindrop adhering to the windshield; and an electronic control unit disposed away from the windshield, the front monitoring camera, and the raindrop detection camera, performing an image processing on an image data of a front image from the front monitoring camera, and performing an image processing on an image data of a windshield image from the raindrop detection camera.

Abstract: A raindrop recognition device is configured to recognize a raindrop on a transparent panel. The raindrop recognition device includes a storage unit, an image input unit, and an image recognition unit. The storage unit stores a trained model that is a machine learning model trained using, as training data, images of the transparent panel with adhered raindrops and images of the transparent panel without adhered raindrops. Image data of the transparent panel taken by a camera is input to the input unit. The image recognition unit is configured to calculate a value representing a raindrop likeness of an object on the transparent panel in the image data by inputting the image data to the trained model. The trained model is trained by training data including images of the transparent panel with uniform background and images of the transparent panel with light source.

Abstract: A camera device includes a windshield information detection camera and a vehicle exterior information detection camera. The windshield information detection camera captures an image to obtain information about a surface of a windshield. The vehicle exterior information detection camera captures an image to obtain information about the vehicle exterior. The windshield information detection camera and the vehicle exterior information detection camera are fixed to a vehicle in a state in which they are also fixed to each other.

Abstract: This transparent shield device has a windshield that is disposed in the sensing direction of an onboard camera. The windshield has an outer surface that is exposed to the outside. The outer surface has an extended imaging area, which includes the imaging area of the onboard camera, and a surrounding area. Furthermore, the transparent shield device has a water-repellent sticker that is positioned within the extended imaging area and/or a water-attracting coating layer that is positioned within the surrounding area. Liquid droplets deposited on the outer surface can be moved out of the imaging area or prevented from entering the imaging area from the surrounding area.

Abstract: In a vehicle wiper device, a retaining portion is formed inside an arm piece at respective areas of a base end side fixing section, a main body, and a leading end side fixing section of the arm piece. A hose is retained by the retaining portion. This thereby enables the hose to be retained to the arm piece without using a retaining member, such as a holder, to retain the hose to the arm piece. Moreover, disposing the hose inside the arm piece enables the hose to be suppressed from being exposed or projecting out from the arm piece. The hose can accordingly be retained in the arm piece without having a detrimental effect on the appearance and while suppressing an increase in cost of the vehicle wiper device.

Abstract: A vehicle wiper device includes a wiper arm, a drive source, a drive shaft that is pivoted by the drive source, and a wiper arm urging member. The wiper arm urging member includes a swing member, an inclination member, a rod, and a compression spring. The inclination member includes a wiper fixing portion and a drawing portion. The rod includes a basal end supported by the drawing portion. A first end of the compression spring is supported by the swing member and the second end applies an urging force to a distal end of the rod. The compression spring acts to draw the drawing portion and urge a distal end of the wiper arm toward a wiped surface.

Abstract: A drive unit includes an output shaft, a drive source, which causes the output shaft to rotate in a reciprocating manner within a first angular range, an arcuate movement portion, which performs arcuate movement about the axis of the output shaft as the shaft is rotated, a pivot shaft, and a lever member, which is rotational about the axis of the pivot shaft. As the arcuate movement portion performs arcuate movement, the lever member is rotated, in a reciprocating manner within a second angular range, while changing the engaging position with the arcuate movement portion.
