OICA-CLEPA proposals for amendments to the draft corrective steering/ACSF B1 amendments to UN R79 (revisions to GRRF-82-12/Rev.3 approved at GRRF-82 and subsequently submitted for the March 2017 WP.29 session as WP.29/2017/10).

Proposal for category C automated steering requirements.

Presentation of concept for test procedures and performance requirements for the assessment of automated steering as a collision avoidance/mitigation countermeasure.

Supporting argument in favor of developing provisions for the approval of category C automated steering systems.

OICA concern over the provision whereby a Category B1 system can only be reactivated by a deliberate action of the driver after the system has been switched off. This provision could be problematic should lane-keeping systems become mandatory to the extent that it could be interpreted as meaning that the system cannot be “default-on” after such a manual deactivation.

Presentation of technical capabilities and constraints for radar systems.

OICA revision of the German/Japan draft text for Category C1 ACSF.

Revised proposal based upon document ACSF-12-11.

OICA-CLEPA perspectives on the definition and use of Category C lane-change systems, especially emphasizing the need for human supervision (SAE Level 2 automation).

Proposal based on document ACSF-12-12.

OICA-CLEPA proposals for improvement of the draft text pursuant to open issues from the previous ACSF informal group session.

Proposals concerning capabilities and requirements for ultra-sonic sensors, radar systems, and blind-spot detection and view on HMI and C1-C2 mode confusion issue.

Presentation covering

1. Lane change functional test
2. Abort of lane change test
3. Overriding force test
4. Deactivation test
5. Sensor performance test
6. Sensor blindness test (industry proposal)
7. Engine start/run cycle test (three phases)

OICA-CLEPA “homework” input addressing open issues from the previous ACSF informal group session.

Following bench testing of steering override force of 50 N, all participants concurred that the 50 N force can be easily handled and therefore is appropriate for all categories of CSF, ACSF, and ESF systems.

Proposal for draft amendments to UN R79 for the 15th session of the ACSF informal group

Vehicle manufacturer input concerning override force requirements for automated steering systems, including a proposal for an alternative to fixed limits.

Results of OICA testing of driver reaction times to direction indicator activation and lane-change maneuver.

OICA and CLEPA positions on the development of regulatory requirements for light vehicle automatic emergency braking systems.

OICA proposal to provide a clearer and more precise definition for “stable acceleration”. The definition introduced in document GRB/2017/02 is specified as "when the acceleration from line AA’ to PP’ has a low variation to the acceleration from line PP’ to BB’.” The term “low variation” is imprecise and so OICA proposes the wording “when the acceleration ratio a_{(PP’-BB’)}/a_{(AA’-BB’)} is lower than 1,2.”

Discussion of current issues related to vehicle noise levels, especially given the availability of affordable electronic devices that enable car owners to artificially increase vehicle sound output.

UN R51 allows the use mechanical or electronic devices to control the gear shifting and measures to avoid accelerations greater than 2.0 m/s². However, the measures are not defined and the manufacturer or technical service is not obliged to document the methodology in the test report. This proposal would introduce a table with examples for devices and measures for reference and would require documentation of methodology used.

OICA presentation on modeling, including tire rolling noise and power train noise, of vehicle sound emissions and compliance with UN R51 requirements.

Clarification proposals for ISO B2 fixture to:

1. Solve interference between cushion & seatback parts
2. Facilitate the path seatbelt path in the cushion part
3. No need to define the centre of gravity for the ISO B2.

Proposal as revised during the first DPPS task force session.
