The evolution of autonomous driving vehicles will result in fundamental changes in requirements for automotive architectures. Recently discussed approaches show a trend toward centralization of computation power on one side and the need for redundancy and decentralized aggregation of high-speed sensor and camera data on the other side. This development requires robust data transmission across the car. Ethernet has been established as a flexible in-vehicle network solution for this purpose. The standardization of specific physical layers for automotive applications in IEEE and other organizations ensures compatibility and broad acceptance for data rates from 10 Mbps up to 10 Gbps and even more.
From the cabling hardware and harness point of view, a robust system design is needed to meet the requirements for automated driving. Especially for high data rates of 10 Gbps and above, the automotive industry enters new ground, and there is the question about the maximum data rate that can reliably be transmitted via electrical wires in a car.
This 60-minute Webinar will answer this question by describing the physical effects and limitations of the link segment. Analysis and simulation results will be discussed about the available data capacity of wire-based transmission channels depending on parameters such as link topology, performance of the cabling components, and constraints regarding electromagnetic compatibility. Sufficient margin is required in the definition of electrical parameters for connectors and cables to allow environmental variations, process tolerances, and changes of harness lengths including different numbers and locations of inline connectors in a link. The Webinar will also explain how these effects can be considered to achieve economic solutions. The focus of the presentation will be on essential aspects of the development of economical and robust connection solutions for future applications including:
- Realization of automotive communication links with data rates of 10 Gbps and higher
- Requirements for topologies, component performance, and EMC
- Environmental influences and process tolerances in the automotive environment
- Achievable data rates based on today's established automotive technologies
An audience Q&A follows the technical presentation.
