Abstract
The introduction of high-speed automotive Ethernet to in-vehicle networks has been accelerated by the increase of communication volume resulting from the spread of advanced driving assist systems (ADAS) including autonomous driving. To ensure safety, in-vehicle network products require communication reliability even under severe conditions associated with extreme heat and noise, and therefore electromagnetic compatibility (EMC) performance is one of the important factors. However, conventional trial EMC countermeasures require a lot of efforts and development costs to ensure EMC performance. We have developed a simulation technology to efficiently verify the EMC performance of automotive Ethernet communication systems under various conditions by constructing the physical layer model of a communication system composed of connectors, wire harnesses, and electronic control units.
