Abstract :

With rapid growth in complex requirements in the design of modern vehicles, the necessity of real time operation of advanced applications, considering various electronic control units and applied intelligent systems prerequisite communication technique between every sub-systems within the vehicle. These complex systems vary from safety related systems of the vehicle such as Supplemental Restraint System (SRS) ├ó┬?┬? airbag, Steering-By-Wire (SBW), Adaptive Cruise Control (ACC), Traction Control System (TCS), Anti-lock Braking System (ABS), Electronic Stability Program (ESP), to the comfort systems of a car like central locking system and in-car entertainment gadgets. All of the above systems comprised of several ECUs that are interconnected through in-vehicle networking system. These networking systems must meet the hard real-time constraints of driver├ó┬?┬?s assistant systems as missing a deadline can simply lead to a catastrophe. There are several protocols defined for in-vehicle communication system such as a Local Interconnected Network (LIN), controller Area Network (CAN), Media Oriented Systems Transport (MOST), J1939 and the one that recently has become popular is FlexRay. In this study, the function of FlexRay Protocol in an ultra-important system in a vehicle called Advanced Driver Assistant Systems (ADAS) as part of an electronic stability program (ESP) and anti-lock braking system (ABS) has been envisaged. A suitable choice of networking infrastructure in the early stages of ADASs implementation will influence the overall performance and reliability of the system. Though FlexRay is one of the most sophisticated networking protocols that can be used in such systems, but it provides redundancy, high-speed, fault tolerant and deterministic exchange of data.
