Claim of US Patent No. 10,919,550

1. A method for determining a position of a rail vehicle, the method comprising the following steps:using a distance measuring device provided on the vehicle for obtaining first position-determining distance measurement values;
readjusting the distance measuring device based on position marker information available at a position marker on a track;
using a first position marker information recorder connected to the distance measuring device for capturing the position marker information;
using a second position marker information recorder, being offset relative to the first position marker information recorder in a longitudinal direction of the vehicle, for capturing the position marker information of the same position marker and initiating a generation of second position-determining distance measurement values;
connecting a first evaluation device and a further evaluation device to the distance measuring device;
installing the first position marker information recorder at a front of the vehicle and installing the second position marker information recorder at a rear of the vehicle;
when a given position marker is passed by the first position marker information recorder, adjusting the distance measuring device using position marker information captured by the first position marker information recorder, and then providing position-determining distance measurement values of the distance measuring device, which has been adjusted to the first evaluation device and, with the first evaluation device, determining the position of the vehicle from the position-determining distance measurement values of the distance measuring device, which has been adjusted, until the given position marker is passed by the second position marker information recorder; and
when the given position marker is passed by the second position marker information recorder, readjusting the distance measuring device or a further distance measuring device connected to the second position marker information recorder, by position marker information from a respective position marker captured by the second position marker information recorder, and then providing position-determining distance measurement values of the distance measuring device, which has been readjusted, to the further evaluation device and, with the further evaluation device, determining the position of the vehicle from the position-determining distance measurement values of the distance measuring device, which has been readjusted.
