Discover how A2B and Ethernet technologies will work together to create lighter, simpler, and faster electronic systems within automotive design.
The adoption of HD multicamera systems for parking assistance, 360° vision systems (also known as bird’s-eye view or surround view monitor systems), radar (RF microwave), and lidar (optical) to enhance advanced driver-assistance systems (ADASs) are raising the bar for automotive electronic design. The coexistence of all these systems is a key factor in the development of autonomous vehicles, but it represents a big challenge for any communication bus.
As size and weight are considered for the latest automotive electronic design, A2B is an easy-to-implement technology. It brings power and data over the same UTP, with a deterministic support for fixed latency. For the much-needed extra boost of speed, Ethernet—with the incumbent 100-Base-T1 (and 1000-Base-T1 in the future)—will be a convergent technology allowing the aggregation of multiple data buses, but with an increased complexity for adding power (PoDL) and SW determinism (TSN).
Likely, a mixed solution based on A2B for audio transport and sensors, and a backbone implemented with a high-speed Gb Ethernet for cameras, lidar, and radar, could fit most of the future mid-term needs of the automotive industry.
