RAIN DETECTION BY MEANS OF AN ENVIRONMENT SENSOR FOR CAPTURING THE ENVIRONMENT OF A VEHICLE POINT BY POINT, IN PARTICULAR BY MEANS OF A LIDAR-BASED ENVIRONMENT SENSOR

摘要

The invention relates to a method for detecting precipitation by means of an environment sensor (14) for capturing the environment of a vehicle (10) point by point, comprising the steps of capturing environment points by means of the environment sensor (14) within the field of view (20) of the environment sensor, selecting at least one region (22, 24) within the field of view (20) of the environment sensor (14), determining a point density of environment points captured by means of the environment sensor (14) in the at least one region (22, 24), and detecting precipitation by comparing the point density in the at least one region (22, 24) with a predefined limit value. The invention further relates to a driving assistance system (12) for a vehicle (10), comprising an environment sensor (14) for capturing the environment of the vehicle (10) point by point and a computing device (16), which are connected to one another by means of a data transmission connection (18), the driving assistance system (12) being designed to carry out the method described above.
