A Functional Safety Methodology for Advanced Driver Assistance Systems
Nowadays, there is a large-scale research and investment in automotive safety field, especially for ADAS (Advanced Driver Assistance Systems) in order to make the road vehicles safer as they get more intelligent, more interconnected and more complex, by enabling them to detect and avoid possible accidents, help the driver with changing lanes efficiently and turning in a more accurate way. Almost every automotive OEM is trying to develop an autonomous vehicle now. The automotive companies today spend an immense part of their energy, money and effort and it might lead to make self-driving vehicles part of our lives in a short time. Addition to the benefits of the autonomous vehicles, these vehicles come with some risks also for the road safety. The ISO 26262 is a well-known standard today that defines the functional safety methodology for electrical components of a vehicle. Today, actually there is no direct standard that immediately deals with the functional safety in smart vehicle area and therefore, many developers use this standard as a guideline to design their software and hardware models to make compatible with the functional safety standards. This paper focuses on an overview of a functional safety method that can be applied in autonomous vehicles.
