Abstract: The invention relates to a method for piloting means (13, 14, 15) for driving a motor vehicle (10) according to either of two driving modes, i.e.: —a manual driving mode, wherein the driving means are controlled manually, by the motor vehicle driver (20), and —an autonomous driving mode, wherein the driving means are controlled automatically, by a calculation unit (12) of the motor vehicle. According to the invention, when the autonomous driving mode is exited, the following steps are provided: —acquiring at least one image of the surrounding area in from of the motor vehicle, —calculating a coefficient of visibility of at least a portion of the surrounding area in the image acquired, and c) selecting, depending on said coefficient of visibility, a way to exit the autonomous driving mode, from at least two separate exiting ways.

Abstract: The invention relates to a camera arrangement for a vehicle, comprising a camera (12), wherein by means of the camera arrangement a brightness of the surroundings of the camera is determinable. The camera arrangement comprises a storage device (38) in which is stored at least one brightness reference value (34) capturable by the camera. This reference value (34) is correlated with a corresponding value (36) indicative of a photometric quantity measurable by means of a photometer (14) at this brightness. An evaluation unit of the camera arrangement is designed for comparing a brightness value determined by the camera with the brightness reference value (34). Furthermore, the invention relates to a method for calibrating a camera (12) and for operating a camera arrangement.

Abstract: The invention relates to a vehicle (10) with at least one camera (16), by means of which at least one image area of a surrounding of the vehicle (10) is capturable, the image area comprising a plurality of pixels and being arranged obliquely above a vehicle front as viewed in the direction of travel of the vehicle (10), and with a tunnel detection device (44) designed for determining an average brightness of the at least one image area. The tunnel detection device (44) comprises a device (46) for feature or edge detection, by means of which differences in the brightness of pixels differing from each other are capturable and thus features characterized by abrupt changes in brightness are detectable in the at least one image area. Moreover, the invention relates to a method for operating a camera arrangement for a vehicle (10).

Abstract: The invention relates to a method for detecting raindrops (26) on a windscreen of a vehicle, in which at least one image (30, 32, 34) is captured by a camera. An object extracted from the at least one image (30, 32, 34) captured by the camera is identified as a raindrop (26), if a confidence value assigned (S20) to the extracted object is above a predetermined threshold value. The threshold value is modified (S22) in dependence of the presence of an item (16) within the vehicle path. Moreover the invention relates to a camera assembly for detecting raindrops (26) on a windscreen of a vehicle.

Abstract: The invention relates to a method and a camera assembly for detecting raindrops (28) on a windscreen of a vehicle, in which at least one image (14) is captured by a camera (12), at least one reference object (20) is identified in a first image (18) captured by the camera (12) and the at least one identified object (20) is at least partially superimposed to at least one object extracted from a second image (16) captured by the camera. Raindrop (28) detection is performed within the second image (16).
