In a sensor device for determining ambient conditions of a vehicle, in particular a motor vehicle, comprising at least one transmitter for emitting electromagnetic radiation, in particular infrared radiation, comprising at least three receivers for receiving electromagnetic radiation, in particular infrared radiation, wherein at least one transmitter is assigned to at least one receiver for determining precipitation on at least one glass surface, in particular the windscreen of the motor vehicle, and wherein at least three receivers are aligned for receiving electromagnetic radiation from different angular regions, it is provided as essential to the invention that the spatial receiving regions of at least one first and at least one second receiver are aligned substantially horizontally, that the spatial receiving region of at least one third receiver is aligned substantially upwards.

A method for recognizing directional structures on a window pane of a vehicle is described. The method includes carrying out an assessment of image points of an image of the window pane, which image points are disposed along an evaluation path, a course of the evaluation path being dependent on an expected orientation of the directional structures on the window pane. The method further includes recognizing a directional structure based on the assessment.

A turbidity degree calculating unit calculates a degree of the white turbidity U on a surface of the lens based on a brightness gradient g of an image I (x, y), and a lens cleaning control unit sets a lens cleaning mode for spraying at least one of the cleaning fluid and the compressed air, which is performed by the lens cleaning unit, based on the calculated turbidity degree U.

An image processing apparatus includes a light source configured to emit light onto a glass; an image-capturing unit configured to capture light from an image-capturing region including reflection light of the emitted light from the glass; an object detection filter used to detect an object attached to the glass, light from a portion of the image-capturing region entering the object detection filter; an exposure control unit configured to determine a first exposure amount used in image capturing for a first region where the object detection filter does not exist and a second exposure amount used in image capturing for a second region where the object detection filter exists; and an image analysis unit configured to analyze a captured image obtained by the image-capturing unit. The image-capturing unit switches an exposure amount used in an image-capturing process for the image-capturing region between the first exposure amount and the second exposure amount.

The invention relates to a windscreen wiper motor (10), having a housing (12) for accommodating a gearing arrangement which comprises a gear wheel (20) rotatably mounted in a shaft (13), which gear wheel has, on its outer circumference, a toothing (21) which interacts with a counterpart toothing (19) on a drive shaft (15), wherein the shaft (13) is received in a mount (22; 22a to 22c), which is constructed as a bore, of the housing (12) in an eccentric bush (25; 25a to 25c) for setting the distance (a) between the shaft (13) and the drive shaft (15), and wherein a press fit is formed at least in regions between the mount (22; 22a to 22c) and the eccentric bush (25; 25a to 25c).

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.
