Autonomous Driving and Beyond: The Necessity of High-Speed Automotive Ethernet

Dublin, Sept. 05, 2023 (GLOBE NEWSWIRE) -- The "In-vehicle Communication and Network Interface Chip Industry Report, 2023" report has been added to's offering.

The landscape of in-vehicle communication is undergoing a dynamic transformation, with automotive Ethernet emerging as a key enabler of high-speed, high-bandwidth communication solutions. As automotive Electronic and Electrical (E/E) architecture evolves to accommodate complex in-vehicle functions, the demand for real-time communication and data processing capabilities has surged. Automotive Ethernet, with its high bandwidth, low latency, and reliability, is poised to play a pivotal role in the future of E/E architecture and high-speed in-vehicle communication.

Communication Connection Forms:

Automotive communication is categorized into wireless and wired communication, each with its unique advantages and use cases.

E/E Architecture and Data Surge:

The increasing number of sensors in vehicles has led to a significant rise in vehicle data. To address this surge in data and the need for high real-time communication, automotive Ethernet is emerging as a preferred solution. Its high bandwidth, low latency, and reliability make it suitable for future E/E architecture and high-speed in-vehicle communication.

Zonal Architecture and Automotive Ethernet:

Zonal architecture, characterized by centralized functions and fewer Electronic Control Units (ECUs), necessitates high computing power for central controllers and lower computing power for zone controllers. Automotive Ethernet serves as the data backbone in this architecture, facilitating massive data transmission between central and zone controllers, as well as software and algorithm interactions.

Future Vehicle Network and Ethernet Switches:

Ethernet switches enable information exchange between zone controllers in future vehicles. Companies like Marvell, Broadcom, and NXP are driving the development of the next-generation vehicle network architecture.

Growing Penetration of Automotive Ethernet Chips:

The proliferation of automotive Ethernet chips is supported by the increasing adoption of zonal architecture. In China, the automotive Ethernet PHY chip market is predicted to reach RMB 21.87 billion by 2025, driven by the incorporation of high-speed PHY chips to accommodate the growing number of chips in a vehicle.

Autonomous Driving and Bandwidth Demand:

Autonomous driving requires real-time data transmission and storage. High-definition data from sensors necessitates higher in-vehicle network bandwidth. As autonomous driving advances, the demand for high-speed communication networks, particularly 10G+ automotive Ethernet, will grow. L4/L5 autonomous vehicles are expected to rely heavily on 10G+ automotive Ethernet.

Marvell's Brightlane Q622x Switches:

Marvell's Brightlane Q622x family of central Automotive Ethernet switches supports zonal networking architectures in next-gen vehicles. These switches aggregate traffic from devices within a zone and connect to the central computing switch via high-speed Ethernet. The switches offer bandwidth up to 90 Gbps and multiple port configurations.

Increasing Automotive Ethernet Ports:

With evolving E/E architecture, the penetration of automotive Ethernet is increasing, resulting in a higher demand for Ethernet node chips. The number of automotive Ethernet communication ports is expected to exceed 100 in intelligent vehicles.
