Abstract: A device for detecting rain includes a camera and a lighting source for emitting visible light onto a window. The camera and the lighting source are configured and arranged in such a way that the camera can detect a signal of the visible light which the lighting source emits onto the window. The signal which is detected by the camera correlates with visible light of the lighting source, which visible light is reflected or scattered at the inner face of the window or outer face of the window and/or at the raindrop. The visible light passes through a shutter device which causes the light to be blocked or highly attenuated in a predefined direction perpendicular to the illumination direction of structures of the shutter device. In contrast, the light in the direction perpendicular to the predefined direction and to the illumination direction can propagate virtually unimpeded through the shutter device.

Abstract: A driver assistance system for a motor vehicle has a surroundings sensor and an evaluation unit for evaluating the surroundings sensor data. The evaluation unit receives data from a positioning device. Furthermore, a reduced or limited subset of data taken from a digital roadmap is stored in a non-volatile memory, which is provided to the evaluation unit. The reduced data are selected to include only data relevant for the function(s) of the driver assistance system. Thereby the driver assistance system does not need to be connected for data transmission with a navigation system.
