The individual driver assistance functions available in vehicles today are, step by step, evolving into highly complex interrelated systems designed to make fully automated driving possible. The path leads from alarm-based support functions to assisted driving, such as lane departure warning systems, to functions that take partial control of the vehicle, such as the highway chauffeur or valet parking and finally to completely autonomous cars. Along with these developments, the requirements for transmission rates that must be able to handle large amounts of data are increasing significantly, thus turning Automotive Ethernet into a key technology for future vehicles.
