Abstract (en)
[origin: EP2796337A1] Method for determining the track course of a track bound vehicle, the method comprising the following steps: a) defining a first error distribution of a curvature determination error for a plurality of erroneously measured track curvatures around a first estimated curvature value k 1 , b) defining a first threshold T 1 according to a predefined first wrong decision probability, whereby any measured track curvature beyond this threshold is considered not to be the first estimated curvature value k 1 , c) defining a second error distribution of a curvature determination error for a plurality of erroneously measured track curvatures around a second estimated curvature value k 2 , the first estimated curvature value k 1 being smaller than the second estimated curvature value k 2 , d) defining a second threshold T 2 according to a predefined second wrong decision probability, whereby any measured track curvature beyond this threshold is considered not to be the second estimated curvature value k 2, the second threshold T 2 being located on this end of the second error distribution facing towards the first error distribution, e) whereby the distance between the first and second estimated curvature values k 1 and k 2 is chosen such that T 1 = T 2 or T 1 <T 2 , f) measuring a track curvature of the track bound vehicle, whereby the measured curvature value is considered to be k 1 if it is <T 1 and is considered to be k 2 if it is >T 2 .
