UN regulators tabled an event recorder amendment that triggers on emergency braking
A proposal put to the World Forum's general safety working party in Geneva would make the event data recorder capture automatic emergency braking interventions and log drowsiness warnings issued up to an hour before a crash.
The 132nd session of the World Forum for Harmonization of Vehicle Regulations’ general safety working party opened in Geneva on the afternoon of September 28, with a proposal for a third series of amendments to UN Regulation No. 160 on its agenda. The paper was submitted by the informal working group on event data recorders and data storage systems for automated driving, and distributed on July 14.
The central change is a new trigger class. Alongside the existing crash triggers, the draft would record an event on “emergency braking demand by the advanced emergency braking system in response to detecting the possibility of an imminent collision”. The group’s justification was that collisions involving vulnerable road users “may be missed by the currently defined triggers”. Deployment of a rollover protection system and of a vulnerable-road-user secondary safety system would also become triggers.
The draft adds mandatory data elements, including the status of the driver drowsiness and attention warning system and the time since a warning was issued, over a proposed window of up to 60 minutes. Advanced driver distraction warning, blind spot monitoring, turn signal, emergency stop signal and driver control assistance system status join the list, together with time to collision recorded from zero to 5.0 seconds. The sample rate for several elements rises to 10 Hz.
Several values remain in square brackets, and the paper is a proposal tabled for discussion rather than an agreed text. The session runs to October 2, and its report is not expected for some weeks.
