Embodiment Construction

[0040] figure 1 The light beam sensor module 101 is shown with a housing 103 which is designed such that the light beam sensor module 101 can be arranged on the inner side of the vehicle windshield 102 at the height of the foot of the rearview mirror. The windshield 102 closes the open front face of the housing 103. For clarity reasons figure 1 The light beam sensor module 101 is shown in a cross-sectional view, so the wall of the housing 103 that closes the side is not shown and opens the viewing angle to the inside of the housing 103. The beam sensor module 101 also includes: a detector element 104, which is designed, for example, as an indium-gallium-arsenide-photodiode; and a blocking filter 105 for reducing the influence of interference factors caused by sunlight on the detector element 104 Convex lens 111, the convex lens will reflect the sensor beams 106, 106' and all sensor beams (not shown) between the sensor beams 106 and 106' to converge on the detector element 104 f...

Abstract

The invention relates to a method for determining the condition of the road ahead in a vehicle, according to which method the road surface (113) is illuminated with sensor beams (106, 106'), said sensor beams (106, 106 ') being reflected and absorbed in accordance with the condition of the road surface (113) and the condition of the road being determined on the basis of the reflected sensor beams (115). The method is characterised in that the road surface (113) in front of the vehicle in the direction of travel is illuminated. The invention also relates to a corresponding beam sensor module.

Description

Technical field [0001] The invention relates to a method for proactively determining road conditions in a vehicle according to the preamble of claim 1 and a method for proactively determining road conditions in a vehicle according to the preamble of claim 7 Status of the beam sensor module. Background technique [0002] Many different sensor systems for detecting the environment are already known in the prior art for the automotive field. With the aid of this sensor system, for example, other vehicles, road signs or lane boundaries can be detected. As sensors, camera sensors, lidar sensors, laser sensors or radar sensors are often used here. The environmental information detected in this way can also be used for safety-related interventions, such as autonomous braking or steering interventions. In addition, there are also known vehicle sensors that first determine the state of the vehicle, and the vehicle sensors can also implement inferences about environmental conditions, su...
