Abstract: A method for determining a headlight range alignment of at least one first headlight of a motor vehicle. The motor vehicle includes at least one optical sensor which is designed for detecting at least one part of a first illuminated area of the first headlight and generating a first image having the part of the first illuminated area. The method includes the following steps: reading in the first image from the optical sensor, selecting at least one first image area in the first image, whereby a cut-off line of the first headlight is intended to be imaged in the first image area, and determining the headlight range alignment as a function of the first image area.

Abstract: A method is provided for operating a driver assistance system of a vehicle, including the following steps: formation of video data that correspond to an object in a surrounding environment of a vehicle, formation of at least one motion parameter of the object relative to the vehicle, based on the video data, and standardized to a distance between the vehicle and the object, calculation of a collision-related threshold value based on the standardized motion parameter, the driver assistance system carrying out an action as a function of a comparison between the threshold value and a collision-related parameter. A driver assistance system, a vehicle, and a computer program are also provided.

Abstract: A filtering method for sensor data formed by a sensor system for acquiring objects, including: measurement of a scaling value from the sensor data, the scaling value corresponding to a change in size of an object from the sensor data over a time interval, determination of a measurement error parameter of the scaling value, and execution of a Kalman filtering based immediately on the measured scaling value, the time interval, and the measurement error parameter, in order to estimate at least one normalized motion parameter of the object relative to the sensor system. A related filter device, a driver assistance system, and a computer program are also described.
