In addition, the higher the level of the autonomous driving system, the number of independent sensors will also increase greatly, and the total amount of data generated will also be larger. For example, Level 2 autonomous driving systems can provide longitudinal and lateral vehicle motion control, so drivers can let go of their hands and take a break from their eyes. The system may require the use of 5 RADAR sensors and 5 cameras. Fully autonomous driving systems (levels 4 and 5) will require up to 20 RADAR sensors and 6 cameras, as well as use V2X communication. We predict that a self-driving car will generate about 4 terabytes of data per day. This data needs to be transmitted, stored, and shared over high-speed, reliable networks with extremely low latency, which is the strength of high-throughput, low-latency networks based on in-vehicle Ethernet.
