Recent paper is addition to the previously published papers and articles of the author in themes of vehicle sensory systems and, due the connection matrix, can serve for further study, as for reliability calculations of the sensory and control systems of the electric vehicles. At the beginning of paper, the detailed hierarchical model of the EV (Electric Vehicle) has been created, later from this map the graph-map of the system is formed based on FCM model, and at the end the “connectivity-matrix” and suggestion for creating the “reliability-matrix” of the system is explained. At the end of paper, the table of acronyms (NOMENCLATURE) can be found.
