UN Regulation No. 137
Restraint System in Frontal Impact

Uniform provisions concerning the approval of passenger cars in the event of a frontal collision with focus on the restraint system

This regulation provides for a full-width rigid barrier frontal impact test to evaluate the performance of occupant restraint systems. Briefly, the test involves a 50 km/h impact of a vehicle equipped with a Hybrid III 50th percentile male driver and an HIII 5th percentile female front passenger. Aimed particularly at reducing injuries to the elderly, the test sets a 42 mm ThCC threshold that will be strengthened to 34 mm for the HIII 5F in 2020 (via the 01 series amendments).

21 Mar 2018 21 Mar 2018 | ACEA Position Paper: General Safety Regulation Revision ACEA and EU European Automobile Manufacturers' Association and European Union Global Technical Regulation No. 7: Head Restraints This regulation specifies requirements for head restraints to reduce the frequency and severity of injuries caused by rearward displacement of the head (i.e. whiplash from rear-end collisions). A second phase in the development of this rule is underway to address the following:
  1. new headrest height requirements;
  2. a dynamic test to mitigate both short and long term whiplash injuries;
  3. evaluation of dummy use and injury criteria vis-à-vis biofidelity and correspondence with real world accidents.
GRSP is expected to consider an informal proposal, addressing all issues, including a draft Addendum 1 to the M.R.1 at its December 2016 session. AC.3 agreed to extend the mandate of the IWG until March 2017.

ESS would amend UNECE Regulations 13 and 13-H on heavy and light vehicle braking, respectively, to incorporate systems that automatically signal sudden hard braking of motor vehicles to following vehicles.

Of current concern is the risk of regenerative braking systems (as used in hybrids and electric vehicles) to interfere with and/or mimic the behavior of ESS systems.

VRU Proximity Awareness Awareness of Vulnerable Road Users in Low-speed Maneuvers WP.29 Regulatory Project Awareness of Vulnerable Road Users in Low-speed Maneuvers, In 2018, EDR became a priority in the WP.29 programme of work in relation to automated vehicle work and proposals for a Data Storage System for Automated Driving (DSSAD). In 2015, the UK Department for Transport published a Regulatory Review around Driverless Cars. This looked at whether such vehicles could be tested in the UK and which areas of legislation would need to be changed prior to everyday use of driverless cars. The Review found that event data recorders would be an essential element for the widespread use of driverless cars, given the need for a definitive record of the actions the driver and/or vehicle may or may not have taken prior to a collision. Therefore, the UK raised this topic during the May 2015 GRSG session and asked that EDR be added to the agenda for the October 2015 GRSG session.
