Background
The ITU Collaboration on ITS Communication standards (
CITS), which serves as an international platform for the coordination of globally acceptable and harmonised standards on Intelligent Transportation Systems (ITS), established, in September 2023, the Expert Group on Communications Technology for Automated Driving (
EG-ComAD). At its second meeting, on 12 September 2024, the EGComAD established the second of its working groups:
WG2 on “Vehicular communications for advanced emergency braking, including to
protect VRUs”.- WG2 is collecting automotive requirements to enable “Vehicular communications for advanced emergency braking, including to protect VRUs”, thus expanding current AEB technologies such as cameras and radars to allow for larger ODDs up to long distance and High Speed;
- This effort is aimed for a possible next generation of vehicular communications that addresses automotive safety, possibly by 2032.
Topics in Focus
The U.S. NHTSA has announced extended regulation for advanced emergency braking, including to protect VRUs. It will implement the new Federal Motor Vehicle Safety Standard that will make extended requirements for automatic emergency braking (AEB), including pedestrian AEB, standard on all passenger cars and light trucks by September 2029. This safety standard is expected to significantly reduce rear-end and pedestrian crashes.
The new standard, FMVSS No 127, requires that “all cars be able to stop and avoid contact with a vehicle in front of them up to 62 mph and that the systems must detect pedestrians in both daylight and darkness. In addition, the standard requires that the system apply the brakes automatically up to 90 mph when a collision with a lead vehicle is imminent, and up to 45 mph when a pedestrian is detected”.
The initial implementation of “Vehicular communications for advanced emergency braking, including to protect VRUs” is expected to be for all U.S. light vehicles (gross vehicle weight rating of 10,000 pounds or less).
As this is the first regulation with such requirements, it likely to set a bar for the AEB worldwide. WG2 will study if vehicular communications will assist in meeting this AEB requirement.
A non-exhaustive list of items for WG2 is:
- Collect and organize relevant accident situations from the field in which vehicular communications will allow for efficient, up to long-range and high-speed advanced emergency braking, including to protect VRUs;
- Define the most relevant accident scenarios in which vehicular communications;
- Define which requirements for vehicles to benefit from vehicle communications included with AEB, safely, and with the required reliability up to high-speed situations;
- Build a consolidated functional safety perspective for vehicular communications for advanced emergency braking, including to protect VRUs across major vehicle manufacturers;
- Collect large, complex examples of the high-speed AEB environment in all major jurisdictions as well as appropriate other jurisdictions;
- Identify the level of failure that authorities in different jurisdictions might be able to accept.
Work on requirements for vehicular communications for advanced emergency braking, including to protect VRUs identified by other groups will be included.
