Rich Autonomous Functions under Driver Supervision


The SAE Level 2+ (L2+) trend continues to gain traction in the automotive market. Systems developed by Tesla, Mobileye, and NVIDIA are set to deliver a comprehensive set of autonomous driving functions, including urban driving, highway automation, lane changes, and merges, etc.—features that are more often associated with a fully autonomous vehicle or robotaxi. The critical difference between these L2+ vehicles and the typical Level 3 or Level 4 vehicle is the role that the driver plays in providing redundancy to the L2+ system. The driver retains responsibility for the vehicle, allowing automakers to begin deploying and monetizing their autonomous vehicle investments without exposing themselves to liability, or waiting for a step change in any laws that may preclude deployment of unsupervised autonomous functions in the targeted region.

This raises an important question: what components are needed to deliver a vehicle with rich autonomous functions, but with redundancy provided by the driver? Which of the technologies seen of the typical unsupervised L4 prot…
