1. A method for analyzing conditions of technical components of a track bound vehicle in view of a rarity and/or an abnormality of a condition, the method comprises the following steps of:
a) describing the conditions of the technical components in a behavioral input space being spanned by state variables, which are characteristic for the technical components;
b) analyzing the condition of a technical component of the technical components in respect to other conditions of the technical component in the behavioral input space, whereby the rarity of the condition of the technical component is detectable, wherein step b) comprises the sub-steps of:
determining a distribution of the conditions of the technical component in the behavioral input space for the analyzing of the conditions of the technical component;
identify characteristic regions in the behavioral input space by using a distribution of the technical component in the behavioral input space; and
determining a number of the conditions of the technical component in at least one characteristic region of the behavioral input space;
c) analyzing the condition of the technical component also in respect to analyses of conditions of further technical components in the behavioral input space, whereby the abnormality of the condition of the technical component is detectable, wherein step c) comprises the sub-steps of:
determining a number of the conditions of the further technical components in the at least one characteristic region of the behavioral input space for analyzing the condition of the technical component also in respect to analyses of the conditions of the further technical components; and
initiating counter measures for secure operation of the technical component upon detecting the technical component as a failing technical component and/or ordering a new technical component for replacing the technical component.
