Dealing with Functional Safety Requirements for Automotive Systems: A Cyber-Physical-Social Approach

Road transport system is one of the essential infrastructures in the world, where the majority of the population use its facilities on a daily basis. That is why ensuring their safety has been always a growing concern for most authorities. The automotive industry is already aware of that, and the ISO 26262, a standard for developing functional safety systems for vehicles, has been developed. Although current studies have shown that the root cause for most of the accidents has shifted from vehicle-centric to driver-centric, the main objective of ISO 26262 is covering electronic and electric (E/E) systems of vehicles with almost no emphasis on the driver itself. To this end, we propose a holistic approach based on the ISO 26262 standard that not only considers the E/E systems of the vehicle but also the driver's behaviour. We illustrate the utility of the approach with an example from the automotive domain.
