Title: MEASUREMENT OF DISTANCES BETWEEN A RAIL VEHICLE AND OBJECTS ARRANGED TO THE SIDE OF THE RAIL VEHICLE
Abstract:
The invention relates to a method for measuring distances between a rail vehicle and objects arranged to the side of the rail vehicle (1), in particular a platform edge (7), during the journey of the rail vehicle (1), wherein - during the journey, a first measuring system (12), in particular an ultrasonic measuring system, is used to repeatedly measure first measured values of the lateral distance, - during the journey, a second measuring system (13), in particular a laser measuring system, is used to repeatedly measure second measured values of the lateral distance, - the accuracy of the first measuring system (12) is greater than that of the second measuring system (13), but the measurement frequency, that is to say the frequency with which measured values are recorded, of the first measuring system (12) is lower than that of the second measuring system (13), - distance values are calculated by combining the first and second measured values, which distance values represent the lateral distance of the rail vehicle (1) on the basis of the time during the journey and/or on the basis of the location on the route.
