Earlier this year, SAE International published an Information Report categorizing and defining various levels of automated driving. Now it is offering a handy and free two-page document at http://www.sae.org/misc/pdfs/automated_driving.pdf to illustrate and summarize the categories. The full Information Report (J3016 - "Taxonomy and Definitions for Terms Related to On-Road Motor Vehicle Automated Driving Systems" at http://standards.sae.org/j3016_201401/ includes operational definitions for advanced levels of automation and related terms. SAE says the report provides a foundation for further standards development activities and a common language for discussions within the broader “automated/autonomous vehicle community." In related automated-driving news, Mercedes-Benz recently received a license permitting it to test vehicles in autonomous driving mode in daily traffic on California's roads. Audi and Google previously had been granted licenses.
