This extraordinary session has been scheduled to advance the work on automated steering systems under UN R79 (i.e., automatically commanded steering functions, or ACSF). The deadline for the submission of official working documents is 22 September 2017.
5. The Chair of GRRF recalled the purpose of ECE/TRANS/WP.29/GRRF/2017/27 proposing amendments to UN Regulation No. 79 with provisions for Automatically Commanded Steering Function (ACSF) of Category C, Emergency Steering Function (ESF) and clarifications to Annex 6. He mentioned that the Informal Working Group (IWG) on ACSF held two meetings and a webex conference since the September 2017 session of GRRF to review this document.
6. The expert from Germany presented (GRRF-85-06 and GRRF-85-07) the outcome of the IWG on the draft provisions applicable for ACSF of Category C (GRRF-85-02). He explained that the IWG resolved the remaining issue on the definition of the point at which, following the beginning of the Lane Change Procedure, the driver’s reaction should be understood. He added that, for this purpose, continuous lateral movement and lane centering provisions were added. He continued his presentation by reporting on the deliberation of the IWG on the definition of the target vehicle used for the sensor performance test proposed in Annex 8, para. 3.5.5. He added that the worst case scenario would be a sensor performance test with a motorcycle of category L3 target coming from the rear of the subject vehicle. He noted that no standard defining a test target L3 vehicle would exist to date and that therefore the IWG agreed on the compromise defined in Annex 8, para. 3.5.5.1. He noted that the definition of the target vehicle should be reviewed at a later stage as some experts had expressed their doubts that a L3 vehicle without fairing and windshield would indeed be the worst case scenario for this sensor performance test. He concluded his presentation with the description of the type approval tests requirements to be included in Annex 8. GRRF agreed that using a motorcycle without fairing and windshield would be appropriate until such times that a uniform target would be agreed.
7. GRRF reviewed in detail GRRF-85-02 and agreed on a number of amendments as reproduced in GRRF-85-02-Rev.1.
8. The expert from the United Kingdom of Great Britain and Northern Ireland introduced GRRF-85-01-Rev.1 proposing amendments to Annex 6. The expert from Japan introduced GRRF-85-05 with amendments to GRRF-85-01-Rev.1.
9. GRRF reviewed both documents in detail and agreed on a number of amendments as reproduced in GRRF-85-01-Rev.2.
10. The expert from OICA presented (GRRF-85-08) a proposal for provisions applicable to ESF (GRRF-85-03).
11. GRRF reviewed the latter document in detail and agreed to insert the definition of ESF contained in GRRF-85-02.
12. GRRF adopted ECE/TRANS/WP.29/GRRF/2017/27 with the amendments endorsed during this session concerning ACSF of Category C, ESF and Annex 6, as reproduced in Annex II to the session report and requested the secretariat to submit it as draft 03 series of amendments to UN Regulation No. 79 to World Forum for the Harmonization of Vehicle Regulations (WP.29) and Administrative Committee of the 1958 Agreement (AC.1) for consideration and vote at their March 2018 sessions.
13. GRRF noted the necessity to further develop Transitional Provisions applicable to the draft 03 series of amendments to UN Regulation No. 79 (see para.12 above). GRRF reviewed the proposal tabled by the expert from OICA (GRRF-85-04), agreed on the necessity of transitional provisions (GRRF-85-04-Rev.1) and requested the Chair and the Secretary to further develop the Transitional Provisions accordingly, also taking into consideration the newly adopted Transitional Provisions applicable to the 02 series of amendments.
