Proposal to correct erroneous references (to annexes in the regulation as well as to UN R94 and R95) in the text and to correct an inconsistency in the text (paragraph 26.7.2. refers to situations where the AECS is not equipped with a back-up power supply; however, the subparagraph 26.7.2.3. refers to an AECS with a back-up power supply).

UN R144 | Amendment 2 (2020)
3 Nov 2020 2021-01-04 08:53:17 UTC 2 01 series of amendments Based upon the adopted proposal: WP.29/2020/29

Proposal to:

  1. clarify that the application of an AECD approval to other vehicle categories than M1 and N1 is not mandatory,
  2. align the power supply requirement of Part III, para. 34.1 with the corresponding requirement in Part II, para. 25.1.
  3. clarify with regard to para. 34.1 that if the vehicle is equipped with both
    • -a “back-power supply” as listed in para. 35.10.1 and
    • -a “Power supply other than back-up power supply mentioned in paragraph 35.10.1” as listed in para. 35.10.2
    both should be tested according to Annex 9. The “Power supply other than back-up power supply mentioned in paragraph 35.10.1” should indeed only be tested if it is the only power supply for the AECS.
  4. include two-year transitional provisions
  5. remove the exclusion of M1 and N1 not equipped with a side airbag and to specify that the AECS shall be able to output the navigation solution in an NMEA-0183 protocol format (RMC, GGA, VTG, GSA and GSV message), among other clarifications.
