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.

Text submitted by the expert from Japan proposing an amendment to document GRVA-05-05 from TF CS/OTA

Proposal to delete limitations regarding the choice of cryptographic modules.

Japan supports the proposal from Germany (GRVA-07-03) to establish an informal working group to develop requirements for heavy-duty vehicle VRU AEBS. Japan proposes to adapt provisions from UN R152 on light vehicle AEBS.

Alternative proposal to clarify the text with regard to transitional provisions and extension of approvals in response to document GRVA-10-12.

Proposal to authorize work on a new UN Regulation for the approval of light vehicles with regard to prevention and mitigation of collisions due to driver error in actuating the accelerator pedal.

Proposal to explicitly note objectives behind provisions requiring manufacturers to perform in-service monitoring and reporting (ISMR) for their driver-control assistance systems approved under UN R171 and for UN R171 to be continually reviewed based on technological progress and data collected via ISMR.

Proposal to simplify the original text.

Proposal to clarify that the tolerance for the speed of the pedestrian dummy crossing the vehicle path is 0.4 km/h across all the series of amendments.

Proposal to correct a reference to paragraph 3.6.1.1.3. that should read 5.6.1.1.3. and to correct a misspelling.

Proposal to amend the draft text (GRVA/2019/9) submitted to resolve measurement concerns in the test requirements for ACSF of Category B1 and C by introducing provisions for tolerances, including:

1. inclusion of the position at which the lateral acceleration was measured and the position of the centre of gravity of the vehicle for better traceablility,
2. sampling rate of at least 100 Hz for dynamic testing,
3. specification of filters and cut-off frequency for determination of lateral acceleration,
4. option to measure “overriding force” torque via an internal sensor or an external device (e.g., steering robot).

This document summarises the reviews conducted by the GR working parties on the fitness for ADS of UN Regulations and GTR for application to ADS vehicles. This document represents the current opinions of the experts at the time of submission, and the recommendations contained inside may evolve significantly during the next steps of the process of reviewing and amending Regulations.

Plans to validate performance thresholds and test procedures for hydrogen effects on slow-strain-rate tensile (SSRT) and related durability/fatigue properties.

Japan rationale for proposing Humid Gas Stress Corrosion Cracking (HG-SCC) test methods and performance requirements.
