In-vehicle networks and ECU testing
Automotive Ethernet and other bus systems
Inside a typical car, you will find over 100 electronic control units (ECU) controlling everything from brakes, transmission, engine, A/C, steering, cameras, radar, acoustic sensors to the non-cellular and cellular wireless communications.
ECUs talk to each other via car buses, including controller area network (CAN), media oriented systems transport (MOST), local interconnect network (LIN) and FlexRay.
Automotive OEMs and Tier 1s are moving away from mixing so many different bus types to something more uniform, enabling higher data throughput, lower latency and less weight in order to reduce complexibility and increase cost-efficiency.
