Presentation in support of the proposal to delete the static test procedure for seat strength (document GRSP-62-12) from UN R80.

51. The expert from Germany gave two presentations (GRSP-62-35 and GRSP-62-36) to introduce a proposal of amendment (GRSP-62-12) to the UN Regulation aimed at removing the static tests and improving the dynamic test on seat anchorages. Referring also to the video presentations Nos. 1 and 2, he provided evidence that seat anchorages tested statically do not reach the same level of safety as that tested dynamically and, therefore, they cannot be considered as equivalent. GRSP agreed to resume discussion on this subject at its May 2018 session and requested the secretariat to distribute GRSP-62-12 with an official symbol.

Presentation concerning point light sources, gray-scale rendering, color noise, and gloss of monitor housing.

Adaptation of ISO 13406-2 to camera-monitor systems for vehicle rear vision, proposing a visual inspection for bright and stuck pixels on the monitor screen.

At night, conventional mirrors reflect headlamps and similar light sources as points of light. This presentation reviews evaluations of camera-monitor systems in rendering point light sources compared against conventional exterior rear-view mirrors and methods for laboratory testing of their performance.

Presentation on the outcomes of a national meeting of German experts and stakeholders in AECS to discuss the proposed technical regulation for the type approval of in-vehicle systems.

• Dr. Behrning indicated that the presentation is not representing an official national German view but is based on his and TUV’s experience and discussions with stakeholders, in order to provide a view of how Germany deals with D-F.
• Procedure is to deduct the difference of the diesel-mode emission (each substance) from the one measured in the D-F mode.
• There is no national approval system. Each vehicle has to be inspected (based on German 70 StVZO)
• CNG-LPG D-F mode is possible according to ECE R67 or R.110. Emissions based on R.49, ESC, ELR & ETC
• European reference fuels are used.
• About 60% of German diesel engines are failing the initial emissions test so it is difficult to find one to convert in order to test on D-F.
• This would be a transition before having something on the European level.
Discussion
• It is difficult to certify an engine if they don’t know what the baseline diesel engine emissions are.
• Need a way to prove system performance and then move to harmonization.
• Germany is more interested in certifying systems to Euro 6 and not any lesser levels. The certifications regarding D-F also are dealt with on a state-by-state basis.
• Systems can’t be low cost, low performance and high benefit.
• There also must be a way to determine how the D-F system itself performs.

Guidelines for the evaluation of optical artefacts of camera-monitor devices during testing under low sunlight condition.

Comments on the proposed amendments to Regulation No. 46 intended to enhance the objectivity of the requirements for camera monitoring systems.
