Keysight Application Note 5992-3430EN | Why Autonomous Driving Systems Will Require Automotive Ethernet
Keysight App-Note :: Why Autonomous Driving Systems Will Require Automotive Ethernet
Major innovation drivers in the automotive industry span three categories: enhanced safety, cleaner environment, and improved convenience with connectivity.
To achieve these goals, automakers, automotive suppliers, governments, academia, and even non-traditional automotive players such as wireless chipset makers, mobile device makers, and wireless service providers are developing Advanced Driver Assistance Systems (ADAS), connected car technologies, and ultimately, autonomous vehicles.
ADAS and autonomous vehicles require a high-bandwidth and low latency network to connect all sensors, cameras, diagnostic, communications, and central artificial intelligence.
The wiring harness is now the third heaviest component in a vehicle, as well as its third most costly system. Wiring harness installation represents 50 percent of labor costs during automobile assembly.
Automotive Ethernet is the emerging solution to these challenges in the same way that WiFi is the foundation for Dedicated Short-Range Communications (DSRC), Ethernet is a well-known, trusted, and ubiquitous solution in traditional local area networking (LAN). The advantages of Ethernet—multi-point connections, higher bandwidth, and low latency—are attractive to automotive manufacturers. However, traditional Ethernet is too noisy and interfer ence-sensitive to be used in automobiles. The IEEE has new standards and protocols to deliver on the specific needs of the automotive industry.
