GRVA | Session 24 | 19-23 Jan

58. GRVA reviewed GRVA-24-20 prepared by the Task Force on ADAS. The experts discussed whether the proposed text would exclude the approval of Remote-Control Parking (RCP) systems.

59. The representative of France presented ECE/TRANS/WP.29/GRVA/2026/8, as amended by GRVA-24-11, aimed to improve the accuracy and reliability of the verification of the driver warnings, hazard lights, and other indicators in relation to the objectively determined RMF initiation point. The representative of OICA proposed an alternative proposal (GRVA-24-38). Both proposals received some comments. GRVA agreed to resume consideration of ECE/TRANS/WP.29/GRVA/2026/8, as amended by GRVA-24-11 and GRVA-24-38, at its next session.

60. The representative of Japan introduced a proposal for corrigendum to paragraph 5.6.1.2.9 in the 02, 03, and 04 series of amendments to UN Regulation No. 79 (GRVA-24-25). GRVA adopted it and requested the secretariat to submit it (see annex IV) as proposal for corrigenda or supplements (as necessary) to WP.29 and AC.1 for consideration and vote at their June 2026 sessions.

61. The representative of Korea presented GRVA-24-10, which aims to clarify the pre-test conditions for measuring steering effort under a failure condition in UN Regulation No.79. Following discussion, GRVA requested the secretariat to distribute GRVA-24-10/Rev.2 with an official symbol at the June 2026 session.

62. GRVA reviewed GRVA-24-20 and GRVA-24-40, which clarify the special provisions for Automated Commanded Steering Functions of Category A.

63. GRVA adopted GRVA-24-40 as reproduced in annex VII and requested the secretariat to revise ECE/TRANS/WP.29/2026/9, tabled for adoption in June 2026. GRVA also requested the secretariat to submit it as supplements to the 03 and 04 series of amendments to UN Regulation No. 79 to WP.29 and AC.1 for consideration and vote at their June 2026 sessions.

GRVA | Session 25 | 18-22 May

45. During the consultations:

  1. The expert from France recalled the purpose of document ECE/TRANS/WP.29/GRVA/2026/8, which aimed to determine the timing of system interventions for verifying compliance with the Risk Mitigation Function (RMF) requirements. He also recalled an alternative proposal discussed at the twenty-fourth GRVA session. He introduced a third option of a more general nature, contained in GRVA-25-52, which superseded ECE/TRANS/WP.29/GRVA/2026/8.
  2. The expert from the Republic of Korea introduced document ECE/TRANS/WP.29/GRVA/2026/19, superseded by GRVA-25-53, which originally proposed pre-test conditions for measuring steering effort under a failure condition in UN Regulation No. 79. The experts preferred to clarify the testing conditions to address the issue and consequently drafted GRVA-25-53/Rev.1, incorporating the correction contained in GRVA-25-38.
  3. The expert from OICA introduced proposals contained in GRVA-25-09 and GRVA-25-34 to extend the scope of the Automatically Commanded Steering Function of Category A to off-road applications.
  4. The expert from OICA also introduced proposal GRVA-25-13 to extend the maximum operational range for remote-control parking. The experts recalled that the justification for the existing requirement was derived from a line-of-sight consideration translated into a maximum distance. The Chair suggested considering functional safety requirements. The expert from Canada called for additional data and shared considerations regarding misuse assumptions. The expert from Norway raised qualitative considerations, including the presence of obstacles.

46. GRVA requested the secretariat to distribute GRVA-24-11 and GRVA-24-38 (from the twenty-fourth GRVA session) with an official symbol in September 2026 and noted that ECE/TRANS/WP.29/GRVA/2026/8 had been superseded.

47. GRVA adopted ECE/TRANS/WP.29/GRVA/2026/19, as amended by informal document GRVA-25-53/Rev.1, and requested the secretariat to submit it to WP.29 and AC.1 as a draft supplement to the 03 and 04 series of amendments to UN Regulation No. 79 for consideration and vote at their November 2026 sessions.

48. GRVA requested the secretariat to distribute GRVA-25-09 with an official symbol in September 2026.

49. GRVA noted GRVA-25-13 and agreed to review a revised proposal (official working document) to be tabled by CLEPA and OICA on the basis of GRVA-25-59, submitted for information. GRVA recommended that additional data be provided and noted the advice from the expert from China that the justification section was not factually accurate with regard to the situation in China.

GRVA | Session 26 | 14-18 Sep

51. The representative of France recalled the purpose of document ECE/TRANS/WP.29/GRVA/2026/32, which had been prepared following discussions at the twenty-fifth session and was intended to address a case encountered during market surveillance activities. The representative of OICA provided comments on the proposal (GRVA-26-23) and also presented an alternative proposal in document ECE/TRANS/WP.29/GRVA/2026/33. Following discussion, the representative of France withdrew document ECE/TRANS/WP.29/GRVA/2026/32. GRVA then considered the alternative proposal contained in informal document GRVA-26-33.

52. GRVA adopted ECE/TRANS/WP.29/GRVA/2026/33, as amended by Annex VIII to this report (based on GRVA-26-33/Rev.1), and requested the secretariat to submit it as part of the draft Supplements 13 and 2 to the 04 and 05 series of amendments to UN Regulation No. 79 to WP.29 and AC.1 for consideration and vote at their March 2027 sessions.
