Examination of Hazard Analysis and Risk Assessment and Exposure Research in the Real Traffic Situation of ISO 26262 for Motorcycles

ISO 26262, an international functional safety standard of electrical and/or electronic systems (E/E systems) for motor vehicles, was published in November 2011 and it is expected that the scope will be extended to motorcycles in a second edition of ISO 26262 going to be published in 2018. In order to apply ISO 26262 to motorcycle, proper estimation of Exposure, Controllability, and Severity are key factors to determine Motorcycle Safety Integrity Level (MSIL). Exposure is a factor to indicate the probability of the state of an operational situation that can be hazardous with the E/E system malfunction. And it is not easy to estimate the motorcycle Exposure due to less availability of back ground data in actual operational situation compared to motor vehicle. Therefore real traffic situation should be investigated in order to provide rationales for MSIL determination. In this study, we examined Hazard Analysis and Risk Assessment (HARA) for motorcycle in accordance with ISO/PAS 19695 and identified motorcycle-specific operational situation. Then we executed field survey for the acquisition of actual operational situation data and estimated Exposure. This paper shows motorcycle-specific issues for HARA and example of motorcycle travelling data useful for Exposure estimation.
