Our new section, SAE Standards News, aims to update readers on the extensive activity in the SAE Global Ground Vehicle Standards development arena, by more than 800 ground vehicle committees comprised of volunteers from global industry stakeholders and SAE GVS staff who support the committee work.
Cybersecurity, connected and automated vehicles and EV charging are the technology trends dominating SAE Ground Vehicle Standards work for 2017—a year that is shaping up to be the busiest ever, noted Keith Wilson, Project Manager, Technical Programs.
Wilson, based in SAE’s Troy, MI, offices, updated Automotive Engineering on recent activity in his group. You can search http://standards.sae.org/ for the status of any of the standards listed below.
Cybersecurity Guidebook—SAE J3061: This is the first automotive product of its kind, according to Wilson, covering a vital topic that has “far reaching” aspects across all mobility sectors. The standard’s best practices are intended to be flexible, pragmatic, and adaptable in their applications within the vehicle industry as well as to other cyber-physical vehicle systems (e.g., commercial and military vehicles, trucks, buses), Wilson noted, and he promises more to come in this area.
Speaking of J3061, SAE is conducting a webinar training package “Keys to Creating a Cybersecurity Process from the J3061 Process Framework” offered by SAE experts on the standard. Two sessions were given in 2016, and three sessions are slated for 2017. More details can be found at http://training.sae.org/webseminars/wb1604/.
Connected Vehicle—SAE J2735, J2945/1, J3067: An area of prodigious standards activity as industry experts and SAE work to keep pace with the vehicle technology that is emerging in this area. Wilson explained that the U.S. Dept. of Transportation issued a proposed rule on Dec. 13, 2016 that would advance the deployment of connected vehicle technologies throughout the U.S. light vehicle fleet. The Notice of Proposed Rulemaking would enable vehicle-to-vehicle (V2V) communication technology on all new light-duty vehicles, enabling a multitude of new crash-avoidance applications that, once fully deployed, could prevent hundreds of thousands of crashes each year by helping vehicles “talk” to each other (www.nhtsa.gov/About-NHTSA/Press-Releases/nhtsa_v2v_proposed_rule_12132016). He reports that SAE has a contract with the Federal Highway Admin. to accelerate the development of industry standards in this important vehicle technology.
As SAE approaches its fifth year of federal-agency funding support related to this area, new Connected Vehicle standards are nearing publication including SAE J2945/0, J2945/2 & J2945/9.
EV charging—SAE J2954: Wilson says electrified vehicle charging is one of the most active and broadest areas of focus for SAE standards committees for 2017. EV charging goes hand in hand with the flurry of standards activity related to electric-vehicle batteries and other EV and hybrid systems, he said. That arena has seen the proliferation of electrified propulsion systems in the commercial vehicle sector as well, including electric and hybrid buses, delivery vans, on- and off-highway trucks and construction and ag equipment.
SAE Standards Committee activities include overhead charging devices for transit buses, large capacity plug-in chargers for commercial vehicles and wireless charging for both passenger and commercial vehicles. Additionally, there are standards under development for the vehicle-to-grid (V2G) interface. “EV charging doesn’t only encompass power transfer; it’s communicating with your service provider,” Wilson noted. “If you pull into a parking lot in a public parking space and there’s a charger there, you can connect to it. You can set it up to charge for X number of hours and to charge at different levels. And, of course, there are different costs”—and the need for standards at multiple levels; see also SAE J3105, J3068, J2953, J2836, J2847 & J2931.
Levels of Vehicle Automated Driving—SAE J3016: “Automated vehicles are made from the building blocks of ADAS [advanced driver assistance systems] and connected-vehicle technology,” Wilson said. “We have an immense amount of activity going on in those building blocks,” including the human-factors area (how the driver and vehicle communicate back and forth).
Published in the second half of 2016, SAE J3016 provides a taxonomy for automated and autonomous driving systems ranging from SAE Level 0 (fully manual driving) to Level 5 (complete autonomous operation). The standard is the only one of its kind and is cited in the recently released NHTSA Federal Automated Vehicle Policy, according to Wilson.
