Required safety component of automotive cyber - physical systems

Abstract

This identification of possible hazardous events is a task for the risk assessment procedure. Current practices for risk characterization is based on known threats, their consequences and damage expectance.

Modern technologies, such as electric, electronic, cyber- physical systems etc. have proven the existence of many

challenges related to their practice and there is potential for improvements in how the hazard characterization can be conducted. Our purpose is to present practical methods that should be applied for hazardous events’ evaluation. Features of electric vehicles fire safety studies are highlighted. These approaches include furthering studies regarding rankings of risk factors and assumptions supporting the analysis. Focusing on events not included in existing studies. A simple example is used to illustrate how efficiency is reduced, due to a lack of a proper risk assessment perception from a safety standpoint. For the wires with polyvinylchloride insulating material with a most widespread cross-sectional areas the

temperature and the time of the reaches the point of self- ignition was established.
