SAE International® Hosts First-Ever Meeting of UNECE World Forum for Harmonization of Vehicle Regulations GRVA in the United States in Troy, Michigan

Record Number of Attendees Convene to Discuss Global Autonomous Driving System Regulations at SAE International’s Ground Vehicle Headquarters

TROY, Mich. (June 6, 2024) – The United Nations Economic Commission for Europe (UNECE) Working Party on Automated/Autonomous and Connected Vehicles (GRVA) recently convened at the SAE International® offices in Troy, Michigan, to discuss global Autonomous Driving System (ADS) regulations.

More than 230 delegates from 55 countries attended in-person at SAE’s offices, with an additional 70+ attending virtually. In addition to being the first time the GRVA has gathered outside of Geneva, Switzerland, this meeting also serves as a GRVA meeting attendee record - recognizing the global cooperation of developing global ADS regulations.

“SAE is honored to host the GRVA working group, which is focused heavily on automated driving, ADAS, and most importantly, safety,” said Christian Thiele, Director, Global Ground Vehicle Standards, SAE International.

Delegates were given the opportunity to experience technologies developed by companies with a presence in North America with “Ride & Drives.” The Ride & Drives included 16 vehicles and more than 500 driving experiences as well as static vehicle displays, displaying various ADS technologies such as:

  • ADAS and Autonomous Driving Solutions (Mobileye Supervisiontm)

  • Safety Driven, Large-Scale Simulation (Foretellix)

  • Hands-Free Driving Technology (Aptiv, BMW, Ford, GM)

  • Interior Sensing Solutions (Bosch)

  • Thermal Sensing Systems (Magna)

  • Camera-Based Driver Monitoring System (Magna)

  • Automated Driving Marker Lights (Mercedes-Benz)

  • Automatic Lane Change Function (Mercedes-Benz)

“SAE organized invaluable technical visits and demonstrations for GRVA,” added Francois Guichard, Secretary to the Working Party on Automated/Autonomous and Connected Vehicles, United Nations Economic Commission for Europe. “They were truly exceptional, showcasing great innovations and enabling regulators from various continents to sequentially test technologies (from multiple brands) related to DCAS (Driver Assistance Systems, the technical term covering Level 2) – a very impressive feat.”

“At the end of the day, the ultimate goal of the GRVA is to save lives,” Thiele added.

About the WP.29/GVRA:
The UNECE World Forum for Harmonization of Vehicle Regulations (WP.29) is a unique worldwide regulatory forum hosted within the institutional framework of the UNECE Inland Transport Committee. Overall, the regulatory framework developed by the World Forum WP.29 allows the market introduction of innovative vehicle technologies, while continuously improving global vehicle safety, and vehicles’ environmental performance.

GRVA is the Working Party preparing draft regulations, guidance documents and interpretation documents for adoption by the parent body, WP.29. GRVA deals with safety provisions related to the dynamics of vehicles (braking, steering), Advanced Driver Assistance Systems, Automated Driving Systems and well as Cyber Security provisions.

GRVA meets three times a year, with around 160 experts present at each session. It gathers the decision makers (the representatives of Countries and REIOs – “the Contracting Parties”) as well as many stakeholders having a technical interest in the work of GRVA: the vehicle manufacturers (cars, trucks, buses etc.), the suppliers, the motorists, the test houses, the consumers representatives to name a few.
