  • SENSOR-CONTROLLED ADJUSTMENT OF ODOMETRIC MEASUREMENT PARAMETERS TO WEATHER CONDITIONS
    Publication number: 20200172135
    Abstract: A method for adjusting measurement parameters of an odometry unit of a rail vehicle includes acquiring sensor data from the interior and/or the surroundings of the rail vehicle with the aid of at least one sensor unit that includes an internal image-recording unit. Weather data are determined on the basis of the acquired sensor data. Lastly, fusion weightings for the fusion of odometric data that have been determined on the basis of odometric sensor data from different types of odometric sensors are defined depending on the determined weather data. An adjustment device and a rail vehicle are additionally provided.
