AEBS informal group proposal to introduce new and enhanced requirements for the car-to-pedestrian test scenario.

The 01 series of amendments aims at increasing the performance requirements in the Car to Pedestrian
scenario by permitting only reduced maximum impact speed compared to the original version of this
Regulation. Thereby the same maximum impact speed is required for the Car to Pedestrian as for the
Car to Car scenario. However, in the original proposal (GRVA/2019/16), the permitted maximum impact speed for an N₁ vehicle erroneously corresponds to that of an M₁ vehicle. This proposal corrects the error.

Presentation in support of the proposals for the 01 series of amendments and for Supplement 1 to UN R152 (respectively, documents GRVA/2019/16 and GRVA/2019/17.

Proposal from the AEBS informal group to improve and clarify the text of the Regulation.

Pursuant to discussions during the 9th session of the informal working group on AEBS for M₁/N₁, paragraphs 6.5.2. (pass conditions regarding “car-to-car moving” collision warning) and 6.6.2. (pass conditions regarding the collision warning in the Car to Pedestrian scenario) were deleted given that pass conditions were already defined by the general requirements. For consistency, this proposal would delete the pass conditions under the car-to-car stationary scenario.

The False Reaction scenarios in Annex 3-Appendix 2 were based on UN R131 (on-highway heavy vehicles) without verification of their applicability to urban light vehicles. Japan has begun research and anticipates proposing changes to the UN R152 scenarios in the near future. This proposal identifies scenarios under study and recommends tolerances for the vehicle and pedestrian dummy placements. Japan also raises concerns over the provision “the AEBS shall not provide a collision warning” in cases where there is no imminent collision risk.
