UN to strengthen and extend use of Advanced Emergency Braking System for trucks and coaches  

The United Nations Economic Commission for Europe (UNECE) has recently announced that the revision of the Regulation 131 on the use of Advanced Emergency Braking System (AEBS) for trucks and coaches, will extend and strengthen its scope.

Scheduled to enter into force in February 2023, the strengthened provisions will be widened to include other road contexts, including in urban areas. It will introduce much stronger automated braking in response to the detection of stationary objects, even if the driver has not been alerted beforehand by a warning system. This is important if, for example, the traffic situation suddenly worsens due to heavily braking vehicles in front.  

The new measures, which build on experience gained with AEBS over recent years, aims at significantly reducing casualties in traffic jam situations.  

The new provisions will also restrict the conditions under which emergency braking assistance systems can be switched off. Once switched off, the systems must be automatically reactivated after 15 minutes, meaning that in practice, the system will be activated almost permanently.  

Additionally, to better protect vulnerable road users, the proposed revisions require heavy vehicles’ AEBS to be able respond to the detection of pedestrians and avoid accidents up to 20 km/h driving speed.
