| Summary | 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. | ||||||||
