Working Party on Automated/Autonomous and Connected Vehicles - Introduction

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. The group supervises around 8 informal work groups (IWGs) and tasks forces. The IWGs documents as well as the calendar of meetings can be found on our wiki.

GRVA is currently chaired by Germany (Mr R. Damm, KBA). The Vice-Chairs are from China (Ms. C. Chen, MIIT) and Japan (Mr. T. Naono, MLIT)

    At its February 2018 session, the Inland Transport Committee (ITC) acknowledged the importance of WP.29 activities related to automated, autonomous and connected vehicles and requested WP.29 to consider establishing a dedicated subsidiary Working Party (Groupe de Rapporteurs - GR).
    Following this request, WP.29, at its June 2018 session, decided to convert the Working Party on Brakes and Running Gear (GRRF) into a new Working Party on Automated/Autonomous and Connected Vehicles (GRVA). The GRRF activities on tyres and couplings were passed to GRB which became GRBP.
