Authors Abstract
Content
Technological advances in automotive industry have resulted in an increased number of Electronic Control Units (ECU)s. These ECUs are used for sensing and controlling actuators in the modern vehicles. Various network protocols have been proposed to achieve scalable and reliable communication amonglarge number ECUs in modern vehicles.Various network protocols have been proposed for invehicle communication,such as Controlled Area Network (CAN), Local Interconnected Network (LIN), Media Oriented System Transport (MOST), and FlexRay. This study compares latency and reliability of CAN-Bus and FlexRay communication protocols. The HSC12 microcontroller is used to implement these protocols, and for secure communication data is encrypted.Our experimental results indicate that the CAN-Bus communication protocol is a better option for hard real-time systems and FlexRay protocol is appropriate for deterministic data transmission, e.g., priority-less message communication.
