8. (b) Remote-controlled Parking

48. The expert from OICA invited the experts of GRRF to witness a demonstration of a vehicle equipped with an RCP system, with the driver being out of his car during the parking manoeuvre and controlling the car’s motion via a smartphone or a smart key. The experts were presented a well-functioning vehicle equipped with various sensors ensuring safety redundancies. A day before on 16 September 2015, the Ministers of Transport of the G7 Countries witnessed a similar demonstration at their meeting at the Frankfurt Motor Show. In their declaration, the transport ministers of the G7 States and the European Commissioner for Transport stressed that “A key prerequisite for the widespread deployment of innovative and reliable technologies in road transport is that modern vehicle systems are legally permissible and suitable for mass production. Revising, as appropriate, regulations applicable in the G7 states, and those established under the agreements administered by the UN World Forum for the Harmonization of Vehicle Regulations (WP.29) – is of crucial importance.”

49. The expert from OICA introduced GRRF-80-18 (i) presenting the system and those Regulations relevant for this system, (ii) concluding that RCP could be type-approved according to Regulations Nos. 79 and 13-H and (iii) in line with the requirements of the 1968 Vienna Convention on road traffic. The expert of GRRF expressed positive comments about the systems and agreed that clarifications should be added in the relevant Regulations to capture the benefits of such systems without compromising safety. The chair recalled that even though correctly type-approved, such system would still be subject to regulations related to the use of road vehicles. He added that the concern related to cyber security should be addressed.

GRRF-80-18 | Remote Control Parking (RCP): A safe and comfortable parking solution
8. (c) Other ITS issues

50. The Chair of GRRF recalled various cases of cyber-attacks (“hacking”) disclosed in specialized media which were not only affecting automated driving vehicles but also conventional vehicles. The expert from the Russian Federation agreed that this subject should be reported to WP.29. He recalled that the Working Party on General Safety (GRSG) already manage regulations on the protection of vehicle against unauthorized use (UN Regulations Nos. 18 and 116). The expert from Japan also agreed that WP.29 should tackle this issue. He added that both the IWGs on ACSF and ITS/AD would have to tackle this issue within their current mandates. He mentioned that special attention would be needed for connected vehicles and especially those allowing “over the air” (OTA) updates. The expert from Germany stated that “eSecurity” is a serious issue and agreed that WP.29 should tackle this matter.

9. Steering equipment
9. (a) UN Regulation No. 79

51. Referring to GRRF-78-27, the expert from CLEPA, on behalf of CLEPA and OICA, introduced ECE/TRANS/WP.29/GRRF/2015/37 proposing to align the requirements to be met in case of the steering system and the braking system of a vehicle share the same energy source with those of Regulations Nos. 13 and 13-H. GRRF adopted the proposal as reproduced below:

Insert a new paragraph 5.3.1.6., to read:

“5.3.1.6.The requirements for the braking performance in paragraphs 5.3.1.4. and 5.3.1.5. above shall not apply if the braking system is such that in the absence of any energy reserve it is possible with the service brake control to achieve the safety requirement for the secondary braking system mentioned in:
(a) Paragraph 2.2. of Regulation No. 13-H, Annex 3 (for M1-, N1-vehicles);
(b) Paragraph 2.2. of Regulation No. 13, Annex 4 (for M2-, M3-, N-vehicles).

Paragraph 5.3.1.6. (former), renumber as 5.3.1.7.

GRRF-78-27 | Proposal for amendments to document GRRF/2014/19 on Regulation No. 79 Proposal to clarify the draft text to align UN R79 with UN R13-H concerning cases where the braking and steering systems have the same energy source. This proposal would clarify and reaffirm that where there is “a failure in the energy supply, the steering system shall have priority”.
GRRF/2015/37 | Proposal for amendment to Regulation No. 79 Proposal to clarify and align the wording of Regulations Nos. 79, 13-H and 13. The current text of Annex 3 of UN Regulation No. 79 covers requirements to be met in case the braking and the steering systems have the same energy source (paragraph 5.3.1.4.), and the same energy supply (paragraph 5.3.1.5.). However these requirements are not aligned with those of Regulation No. 13-H. Paragraph 1.1.2. of Annex 4 to Regulation No. 13-H requires the capacity of a certain number of sudden stops after the energy source failed ONLY in the case where the secondary braking performances cannot be met without energy assisting the muscular energy: see paragraph 1.1.2. The current text of Annex 3 of Regulation No. 79 covers requirements to be met in case the braking and the steering systems have the same energy source (paragraph 5.3.1.4), and the same energy supply (paragraph 5.3.1.5.). However these requirements are not aligned with those of Regulation No. 13. Paragraph 1.1.3. of Annex 7 to Regulation No. 13 requires the capacity for the system of a certain number of sudden stops, after the energy source failed, ONLY in the case where the secondary braking performances cannot be met without energy assisting the muscular energy: see paragraph 1.1.3. The current text of the provisions in Regulation No. 79 could be interpreted as the required number of sudden stops that must be achieved irrespective of the service braking design, i.e. even in the case of assisted braking system.

52. The Secretary of GRSG introduced ECE/TRANS/WP.29/GRSG/2015/12, proposing amendments to Regulation No. 79 related to the recent adoption of a Supplement to Regulation No. 43 introducing Camera-Monitoring-Systems. GRRF adopted the proposal.

GRSG/2015/12 | Proposal for Supplement 5 to the 01 series of amendments to Regulation No. 79 Proposal to adapt UN R79 in line with the proposed addition of camera-monitor systems to UN R46 (indirect vision). UN R79 refers to external mirrors in test procedures involving the vehicle turning circle. This proposal replaces the reference to mirrors with a broader reference to "indirect vision devices" that includes CMS.

53. GRRF requested the secretariat to submit both adopted proposals to WP.29 and AC.1 for consideration at their June 2016 sessions, as Supplement 5 to the 01 series of amendments to Regulation No. 79.

GRRF/2015/37 | Proposal for amendment to Regulation No. 79 Proposal to clarify and align the wording of Regulations Nos. 79, 13-H and 13.
