This presentation aims to introduce the participants with the progression of Electrical / Electronic Architecture over the years, and the corresponding sophistication within in-vehicle networks. Network Communications play an integral part in the vehicle’s architecture, enhancing and advancing the vehicle’s electronic operation. Traditional vehicle architectures mainly consisted of Controller Area Network (CAN) and Local Interconnect Network (LIN) buses, both of which run at relatively slow bit rates and low bandwidth. With the advancement of next-generation architectures (e.g., connectivity, high-resolution surround view camera, high-resolution displays, etc.), today’s vehicles require higher bandwidth networking solutions. The data rate required to support these features can range from 100 Mbps (e.g. Automotive Ethernet) to multiple gigabits (e.g. MultiGig Automotive Ethernet, Automotive SerDes Alliance-ASA, LVDS, etc.). and is accompanied with increased challenges including vehicle integration since vehicles have more challenging EMC, Electrical, and Environmental requirements than consumer electronics.

Participants attending this session will be able to takeaway the differences within architecture types, the evolving industry trends influencing the direction. In addition, we will also cover the networking that is required to achieve the latest architectural requirements. This presentation will also incorporate the signal integrity characteristics, cable-connector assembly evaluation, and post-processing methods we have adopted to evaluate them.
