A greater range of functions generally means an increased number of ECUs. The resulting increased fuel consumption has to be generated by the combustion engine, causing a rise in CO2 emissions. In the electrical vehicles of the future, the increased power consumption will result in a reduced driving range as well as unnecessary strain on the battery systems.The CAN partial networking technology makes it possible to reduce these effects and ensures energy efficiency both during driving operation and idle time. Audi is developing and standardizing this technology in collaboration with other OEMs and semiconductor manufacturers. Partial networking technology will become an inherent part of the Volkswagen Group Networking Technology Kit, with series production planned to begin in 2014.The manuscript deals with the development, application and verification of the partial network technology at Audi as well as the standardization process within the standardization bodies SWITCH, AUTOSAR and ISO.
