BYD, one of the largest automobile manufacturers in China, needed to upgrade to Ethernet for the communication technology in their car network. This modernization shift would connect essential components like the digital instruments, driving data recorder, the panoramic ECU, and the AVB switch allowing faster testing when new capabilities are added. The customer was using an older, but well known, controller area network (CAN) for their system bus. The move to Automotive Ethernet provided higher-quality, lower latency, time synchronization of audio and video in Ethernet standard format to transmit realtime audio and video streams. The upgrade resulted in a reduction of test time by 50% with a Layer 1-7 end-to-end solution.
