Presentation by Mr Bon-Hwan Koo on behalf of Mr Jongsoo Kim (GTR7-07-08):

The results of seat tests at 16 and 20 km/h, using KNCAP protocol, performed in 2009-2010 were presented. The 20 km/h pulse had the peak scaled up, but had the same duration as the 16 km/h pulse.

It was reported that the CV for head and T1 accelerations was <7; there was a high CV for upper neck Fx, lower Fz and upper neck My at 20 km/h, and for lower neck My at both pulses. Other outputs had a CV <10. Upper neck Fz and lower neck Fx were acceptable as were the kinematics.

The study concluded that, in general, the CV was larger at 16 km/h than at 20 km/h, and that head rotation angle, T1 x and Head x accelerations seem appropriate for a GTR. It was reported that other seat models will be tested. Tests will be run with Hybrid III to try and correlate the Hybrid III 12 degree criterion with BioRID measurements.

The data from this study are available for the informal group.

It was noted that the tests were performed in 2009-2010, and it was asked whether the dummy has been checked against the latest checklists to determine whether the dummy was up the current specification. Mr Koo indicated that Mr Kim would be able to advise on this point.

Action all to email questions to Mr Kim at KATRI:
· The neck shear forces were negative, as per the NHTSA tests with a high seat back rotation angle, whereas they were positive in the PDB tests. What was the seat recline angle in the tests?
· Was the repeatability of T1 angle assessed when setting up the dummy?
· A description of the seat back contour would be useful, similar to that in the PDB presentation.

Review of Korean electric vehicle safety research and regulatory activities.

[Representing the] Korean delegation, Mr. Hyuk Jung presented the status of Korean EVS regulation including the report of Korean research activities for EVs. He explained that the revision to the test procedures is expected in 2012. He also expressed that Korea’s KMVSS 305 will harmonize with FMVSS 305.

Results of investigations intended to validate the reduction of tolerances for the BioRID II setting & acceleration pulse in the test procedures by analyzing the variations of test results due to various tolerance levels.

Mr. Alson presented on behalf of the U.S.A. and California (EVE-02-19e), Ms. Chen on behalf of China (EVE-02-16e), Mr. Horie on behalf of Japan (EVE-02-17e), Mr. Choi on behalf of Korea (EVE-02-15e), and Mr. Couroux on behalf of Canada (EVE-02-13e).

Highlights of interesting discussion points following the presentations:

• - Canada’s alignment with the USA on light and heavy duty vehicle GHG emission standards.
• - EV penetration under the US CAFE/GHG LDV rule for 2025, estimated to be approximately 3%.
• - EV labelling.

Presentation on Korean side-impact test results using the WorldSID and ES2 dummies using the Advanced European Mobile Deformable Barrier (AE-MBD).

Overview of Korea Motor Vehicle Safety Standards (KMVSS) implementation of UN R100 on electric vehicle safety and plans to enhance the fire resistance test procedures.

Members of the EVS-GTR informal working group (IWG) continued to exchange information and provided status update on EV and battery research and testing activities. The summaries of the presentations are as follows:

4.1 China:
The representative of China, Ms. Chen Chunmei, presented an update of EV strategies, EV pilot project and standards in China. According to China’s Energy Serving and New Energy Vehicle Industry Development Plan, china is planning to have 0.5million EVs on the market by 2015, and 5 million EVs by 2020. China launched the EV pilot project from 2009 and around 19,000 energy-saving and new energy vehicles have been demonstrated by now. More than 60 EV and infrastructure standards in China have been established and published, focusing on the whole vehicle, key components, and infrastructure, etc., such as GB/T 18384 Safety Requirements for Electrical Vehicles, QC/T 743 Li-ion Battery for EV

OICA questioned whether the Chinese government intends to replace its standards with the GTR once it’s established. China replied that it might revise its related standards on the basis of EVS-GTR. In addition, OICA requested China to identify those standards that are mandatory and those that are voluntary.

4.2 EU:
A representative of the Joint Research Center (JRC), Ms. Lois Brett, on behalf of EU, provided a presentation on the JRC organization, its role and its activities specific to EV battery research. The JRC is establishing facilities for:
• Battery cell performance testing,
• EV battery pack performance testing (up to 160 kW) and
• Battery cell abuse testing.

Using these facilities the JRC will perform pre-normative research in support of the deployment of batteries for vehicle traction. Scientific and technical support will be provided to policy makers concerning e-mobility and electrification of European transport. Furthermore JRC will also provide impartial and balanced scientific evidence to facilitate effective international and European standardization. A number of collaborations have been established including a Letter of Intent on Interoperability with Argonne National Laboratory and a Memorandum of Understanding with EUROBAT. Negotiations are ongoing to formalize agreements with other US DoE National Laboratories including NREL and SANDIA.

4.3 Korea:
The Korea provided a presentation on its fire testing including the localized/engulfing fire test on hydrogen fuel tank and REESS. In conclusion of the presentation Korea provided a proposal for the REESS fire test parameters. The IWG members will discuss this proposal further in future meeting.

4.4 US DOE:
The US Department of Energy representative, Mr. Lee Slezak, provided a presentation on its EV activities and some safety incidents regarding REESS. The presentation included details on the Advanced Vehicle Testing Activity (AVTA) program. The primary goal of AVTA is to provide benchmark data for technology modeling, and research and development programs, by benchmarking and validating the performance of light-, medium-, and heavy-duty vehicles that feature advanced renewable energy technologies including EVs. The US DOE also works with first responders to establish the guideline on how to handle EVs and REESS in an emergency situation.

4.5 US DOT (NHTSA):
On behalf of the US, the Chairman provided an update on NHTSA REESS safety research program. Below is a summary of NHTSA’s Li-Ion battery research main tasks and estimated completion dates:

• Failure Modes and Effects Analysis (FMEA): publication date anticipated after 1st quarter of calendar year 2013.

• Development of test procedures and performance requirements: SAE and Ford are leading 2 separate teams to conduct this task independently. The purpose of the task is to evaluate the FMEA and develop test procedures to mitigate the safety risks. This task is expected to be completed by October 2013.

• Standardized Battery Assessment and Field Discharge Procedure: NHTSA and Argonne National labs are working to identify, develop, and demonstrate methods for the safe management and handling of RESS in post-crash and non-operational environments. Estimated completion date for this task is August 2014.

• Analytical Tools Development Control System Performance Modeling: The purpose of this task is to define required operator warning indicators for RESS safety critical criteria. Research prognostic conditions and warnings for anticipated safety critical events. Volpe National Transportation Research Center is leading this effort to establish basic Fail-Safe Conditions, Diagnostic Codes and indicators, Data Recording/Storage (e.g., EDR), and Safety Prognostic Requirements. The completion date is expected by March 2014.

The German delegate questioned on how the research affects the timing of the development of the GTR. The US delegate expressed that NHTSA is conducting the research as timely as possible, and that the GTR requirements can be developed in the order of their maturity as research results become available.

Professor Younghan Youn presented an evaluation of WorldSID and ES-2 50th male pole side impact test results (PSI-07-04). These tests were part of a WorldSID and PSI joint research program conducted by Hyundai Motor Company and KATRI.

Professor Youn explained that car-to-car accidents are the major source of side impact fatalities in South Korea. UN R95 is applied in South Korea, but a significant proportion of fatalities are due to head injury. UN R95 cannot guarantee head protection. A reduction in head injury fatalities is a benefit that will come from a pole side impact regulation.
WorldSID and ES-2 50th males indicated similar AIS 3+ abdominal and pelvic injury risks in 32 km/h oblique pole side impact tests of the same vehicle model. However, the WorldSID 50th predicted a substantially higher head injury risk and ES-2 indicated a higher thorax injury risk. The WorldSID test was done using the ISO WorldSID seating procedure (draft) and the ES-2 test was done using the EuroNCAP pole side impact seating procedure.

Ms Tylko suggested the WorldSID 50th male may possibly have impacted a seam or sub-optimal portion of the curtain airbag, given the very high head injury risk recorded.

Presentation of results from Korean testing of the FlexPLI pedestrian lower legform tool.

Presentation on approaching vehicle audible signals for quiet electric vehicles.

This presentation compares the currently available test methods and boundary conditions with traffic situations typically occurring in Korea. From the findings, it is concluded that
  • The test method should comprise a component under acceleration in addition to standstill and cruise-by (SAE J2889-1);
  • The necessary sound level of AVAS is 55~60dB(A) in cruise and 60~65dB(A) in acceleration. The proposed value for acceleration is considered as minimum;
  • The AVAS should be active up to a velocity of 25km/h; and
  • Frequency shift measurement also can be conducted outdoors.

Comments

ISO/SAE considered the inclusion of acceleration and outdoor-testing. Eventually this idea was dropped due to poor repeatability.

Korea
Working paper HDH-12-05e was uploaded to the HDH website, but not presented by Korea at the meeting. The secretary drew the attention to the summary slide (page 16), in which Korea indicated to adopt the HILS approach as the second step in the national fuel economy regulation.

Comments on the HDH work program
No input was received.

The original working paper HDH-12-05e was uploaded to the HDH website, but not presented at the 12th meeting. Mr. Lee (KATRI) presented a revised version at this meeting. Korea is currently investigating to replace the existing fuel economy regulation, which is based on a 60 km/h constant speed driving on a chassis dyno, with the WHVC cycle. Analysis of driving conditions showed a good correlation between typical Korean driving patterns and the WHVC. As a first step, Korea plans to introduce the WHVC chassis test into the national fuel economy regulation. As a second step, Korea intends to adopt the HILS method as an option upon completion of the gtr.

As a first step, Korea plans to introduce the WHVC chassis test into the national fuel economy regulation. As a second step, Korea intends to adopt the HILS method as an option upon completion of the gtr.

Korea carried out intensive research on road operation, monitoring and safety assessment of EV and typical drive pattern throughout the last 3 years. The appropriate SPL for AVAS can be determined by comparing human detection of ICEVs. In order to clarify the term ’Practical use’ as included in the GRB proposed guideline for AVAS sound, one must differ between the driving states deceleration, cruise and acceleration. On an ICEV, the SPL increases with acceleration. However so far testing for the development of the test method has only been done in cruise and it needs to be clarified if this is sufficient. The results already presented during the last meeting in Berlin showed data for cruise as well as for acceleration which supported the thesis that sound emission during acceleration is higher than during cruise. Between 2010 and 2012, during 1194 days in several cities, ‘Research of road operation monitoring on the EV’ was carried out. During these days, typical drive patterns were recorded and it turned out, that cruise condition is very rare. In summary the analysis of typical patterns revealed that:

  • Instantaneous acceleration or deceleration occurs continuously in actual road driving.
  • It is hard to see cruise drive patterns especially in low speed.
  • Also, it is not easy to maintain constant speed in low speed.

This leads to the conclusion that:

  • Many transient drive patterns are typical for real traffic situation.
  • Actually, it is hard to maintain constant speed within a low velocity.
  • We have to determine the reference driving condition either minimum level compared to ICEV or the real traffic sound level of ICEV.
  • The generated sound during cruise is close to minimum.
  • Therefore, the SPL should increase if we consider acceleration

ISO confirmed that the test procedure is designed to measure the minimum sound emission. During the development of the method is turned out, that it is difficult to reached repeatable constant acceleration at low speed and out of practical reasons it was decided test in cruise condition. Also ISO can support the finding that during acceleration, the emission is increased compared to the cruise emission at the same speed. The reason in the tyre torque effect. An AVAS only emitting the minimum of typical cruise condition at the respective vehicle speeds would simulate the pure vehicle or powertrain noise. An EV fitted with such an AVAS and under acceleration would however emit a higher noise as the noise coming from tyres would be produced and must be added to the AVAS emission. Therefore it is sufficient for the AVAS to produce cruise sound emission only. It must however be admitted that, an increase in engine speed and the associated increase of noise may occur prior to an increase of vehicle speed.

75. The expert from Korea introduced GRPE-66-03, containing a proposal to develop a new UN GTR on Vehicles Indoor Air Quality (VIAQ), in order to secure consumers’ health and safe driving environment against harmful substances, minimizing emission of the harmful substances upon manufacturing vehicles. The proposal was supported by a presentation (GRPE-66-40) on recent research on the subject.

76. The expert from the USA expressed his interest in the proposal. Answering specific questions from the experts from the USA and the Russian Federation, the expert from Korea clarified that the tests for vehicle indoor air quality were carried out on new vehicles and in laboratory conditions.

77. GRPE agreed to report on this proposal to WP.29 in June 2013. GRPE also recalled that the requests for mandates to amend and/or develop UN GTRs shall be submitted directly by contracting parties to WP.29 and AC.3, inviting Korea to do so.

Presentation on an electric vehicle classification system based upon the concept of “system power”.

12. The 7th EVE IWG meeting once more provided an excellent opportunity for participants to share
information on electric vehicles. The information sharing sessions were divided in two blocks,
the first session was from 11:00-12:00 on October 17, 2013 and the second session was from
9:00-9:30 on October 18, 2013. The sessions included presentations from China and Korea on
the following topics:

• Research of Battery Durability Performance (EVE-07-08)
• New EV policies in China and EV testing results (EVE-07-11)
• EV Infrastructure and Standardization in China (EVE-07-14)
• Introduction to System Power Concept and its Application (EVE-07-06)
• Korea Green Car Fuel Economy Schemes: Status and Prospect (EVE-07-07)
• Wireless Power Charging is Ready for Cars Now (EVE-07-09)

All presentations were very well received and generated much discussion among participants.
The Secretary thanked presenters and encourage all participants to continue sharing available
information to inform the development of the reference guide and potential future activities of the
EVE IWG.

Presentation in support of Korea’s request document WP.29-161-12) to establish an informal expert group to develop a new global technical regulation to protect occupants from harmful emissions originating with materials used in vehicle interiors.

117. The representative of the Republic of Korea presented WP.29-161-12 and WP.29-161-13 complementing his presentation on Vehicle Indoor Air Quality (VIAQ) given at the previous session of WP.29 (ECE/TRANS/WP.29/1104, para. 130). He invited AC.3 to evaluate the possibility of establishing an IWG with the aim to develop a new UN GTR by 2017. He added that Korea would be committed to chairing such a group.

118. The representative of EU appreciated the presentations, but advised to complete first the development of current tasks before starting new activities. He indicated that this issue may already have been addressed by current legislation. The representative of Canada underlined the importance of addressing potential health impacts related with VIAQ. He supported the idea to work in this area taking into consideration the advice of the EU. He suggested focusing on the identification of best practices and the collection of information before undertaking regulatory work. The Chair of GRPE (Germany) supported the considerations of EU and Canada. He stressed the need to collect information and to analyse the subject before deciding upon the need to develop a UN GTR, if CPs see the need for such a step. Recalling the purpose of WP.29-160-38, the representative of the Russian Federation underlined the importance of the impact of pollutants emitted in the atmosphere on VIAQ. He introduced information through document WP.29-161-22, and expressed readiness to present additional information to the March 2014 session of WP.29. He evoked the need of regulatory initiatives aiming at establishing environmental requirements for vehicle design with respect to ventilation, heating, air conditioning and cabin filters. He recalled the work on tyre and brake wear, which he had introduced in WP.29 in earlier sessions, and underlined the importance of taking a holistic approach. The representative of the United States of America stressed the need to distinguish between emissions from materials used in vehicle construction, which were the responsibility of another agency of his country, and emissions due to vehicle propulsion systems.

119. AC.3 invited all participants to collect information on this topic and requested the secretariat to keep this item on the agenda of the March 2014 session for further discussion.

Presentation on Korean indoor (test chamber) and outdoor (road) sound-level tests towards defining quiet vehicle sound requirements. Korea proposes to establish both minimum and maximum sound requirements for audible vehicle alerting systems (AVAS).

Presentation: Frequency Shift Testing (Korea)

The background of the study that was presented was to compare and evaluate indoor versus outdoor testing. Also the need for maximum level of AVAS was looked at.

Three different ICE vehicles were tested, both on a chassis dynamometer and on outdoor facilities. It was concluded that both testing location delivered similar results so that testing can be carried outdoor. One advantage of outdoor testing is the easier availability of testing facilities as there is no limitation for the vehicle length. Also the standardization of indoor test facilities would have to be determined. As these tests were done on ICE vehicles, the transferability of the gathered results to electric vehicles remains to be proven.

Also Korea supports the request from France to set a maximum value for the emission from AVAS.

ISO mentioned some basic findings and the specific concerns on outdoor testing (pitch shifting) have been presented at previous meetings and invites Korea to participate in future ISO work.

Background information gathered in Korea to support the proposal for a new regulation to protect vehicle users with regard to harmful airborne chemical compounds originating from the materials used in vehicle interiors.

65. Having recalled the WP.29 decision to seek more information on VIAQ before taking decisions upon the development of a UN GTR on the subject (as reported under agenda item 2), the GRPE Chair announced that the VIAQ expert from Korea wished to share a presentation on the subject (GRPE-68-11). Unfortunately, he could not attend this session. GRPE agreed to postpone the introduction of GRPE-68-11 to its next session, in June 2014, maintaining this item on the agenda.

Review of Korean results using the heavy-duty hybrid vehicle mode on a chassis dynamometer per the proposed amendment to enable hybrid vehicle testing under GTR No.4

71. Mr. Sokchang Kwon, Director General of the Motor Vehicles Policy Division of the Ministry of Land, Transportation and Maritime Affairs of the Republic of Korea gave a presentation on the results of their national defect investigations on panoramic sunroofs (WP.29-162-15). The Chair of GRSG suggested that this topic be investigated further by GRSG experts to determine whether it is necessary to adjust the relevant UN Regulation No. 43 and UN GTR No. 6 on glazing. Thus, he invited the representative of the Republic of Korea to share these findings with GRSG experts during the forthcoming session in May 2014. The representative of the Republic of Korea (Korea Automobile Testing and Research Institute (KATRI)) introduced WP.29-162-22 showing the detailed results of their investigations on safety issues with panoramic sunroofs. The representative of Japan agreed with the suggestion by the Chair of GRSG. Finally, the World Forum requested GRSG to discuss this issue at its forthcoming session in April 2014.

Presentation on Korean investigations that identify certain conditions under which ceramic printing (black enamel) weakens toughened glass such that the glass no longer meets the mechanical strength requirements of GTR 6, UN R43 or FMVSS 205. Korea proposes amending the UN glazing regulations.

23. Referring to the discussion at the March 2014 session of WP.29 (GRSG-106-04), the expert from the Republic of Korea gave a presentation on the result of a national investigation on defects of panoramic sunroofs (GRSG-106-21). In this respect, he proposed an amendment to Global Technical Regulation (GTR) No. 6 on glazing (GRSG-106-10). GRSG noted a number of comments and concerns that the amendments to the drop test were not appropriate. The experts from Canada and Germany were of the opinion that further amendments to the GTR were necessary. Following the discussion, GRSG agreed to keep GRSG-106-10 on the agenda and to resume consideration of this subject at its next session. The Chair invited all experts to send, in the meantime, their comments to the expert from the Republic of Korea (e-mail: katrietf@ts2020.kr). He also invited the experts from Germany and the Republic of Korea to jointly prepare a concrete proposal.

44. Recalling the submission of GRPE-66-03, WP.29-160-38, WP.29-161-12 and WP.29-162-16, the expert from South Korea introduced GRPE-69-28 on (i) the Korean VIAQ guideline that had proved to be effective, (ii) the standards applied in various countries and (iii) the need to harmonize internationally the VIAQ requirements. He concluded his presentation by proposing that GRPE develop a VIAQ guideline, as a first step. GRPE agreed to report on this matter at the June sessions of WP.29 and AC.3 and to further discuss a possible strategy to tackle this issue at its January 2015 session.

#3: System power determination:
WLTP Subgroup EV has not the sufficient resources to develop a procedure for the determination of the combined power of HEVs within the given timeframe of WLTP phase 1B. Therefore the initiative of EVE IWG is supported to develop such a procedure in a parallel process. A mandate is currently in development under the co-leadership of Germany (H. Holdik) and Korea (D. Choi). H. Holdik gave a short presentation about the scope and tentative timeline (WLTP-SG-EV-06-08).

Thus, this issue is closed in WLTP IWG. Nevertheless it is very important that WLTP Subgroup EV provides input to the EVE group, especially which performance criteria are needed for WLTP. The possibility to extend the scope from HEVs to PEVs and conventional vehicles should be reconsidered.

EVE IWG has proposed to develop a method to determine system power for EV in a request for prolonged mandate. Thus, this issue is closed in Sub Group EV.
Presentation of the document. Development of performance criteria, like system power, from EV under a new mandate for the EVE IWG.
Important that WLTP Sub group EV provides input to the EVE group. Regarding what performance criteria which are requested for WLTP.

Determining power of EVs (EVE-13-05e)
Mr. Hans Holdik (Germany) presented EVE-13-05e, which outlines the proposed work for this topic: the development of a new regulation or recommendation on determination of powertrain performance of hybrid EVs. Mr. Holdik informed the EVE group that there was a clear demand from the WLTP IWG for this work and that the initial focus would be on light duty vehicles (M1, N1). The presentation detailed a number of open questions that would be discussed and clarified in Part A and presented a draft roadmap for the work. Discussion focused on pervious work of the HDH IWG, whether or not fuel cell vehicles were being considered (no), and whether or not the work would consider EVs as well as conventional vehicles (unclear). The EVE Secretary noted to the group that the timeline on Slide 6 would need to be adjusted to reflect the timeline presented in the Roadmap for Part A (EVE-13-06e).

ACTION 6: All interested parties wishing to participate in this work by Germany and Korea should reach out directly to Mr. Holdik (Hans.Holdik@bmvi.bund.de) and Mr. Dongseok Choi (dsechoi@naver.com).

ACTION 7: Germany and Korea will adjust the timeline on Slide 6 to reflect the timeline presented in the Roadmap for Part A (EVE-13-06e).

8. Mr. Hyun-woo Lee presented the existing Korean test standard for vehicle interior air measurement. He explained the rationality behind the standard and its behind achievements since the first issue in 2004.

The expert from Korea, Dr. Lee presented a proposal from Korea on the test parameters (VIAQ-04-07):

• M1 (light duty passenger cars) and N1 (light duty truck) should be tested.
• The production date is the date when the final test of vehicles is finished in the production line.
• Tests should be done for 28d old cars.
• Cars should be transported and stored in a normal way for series cars. Climate system should be in recirculation mode.
• Before the test the cars should be parked in a storage area.
• One day before the test all covers should be removed.
• Soak temperature should be 25°C. Soak time should be 16h.
• Each car should be tested twice.

Proposal for ACSF systems to be programmed to function only within the maximum speed limits defined by national or regional traffic authorities.

31. The expert from the Republic of Korea introduced GRSP-61-24 to inform GRSP about research and safety testing activities on L7 categories of vehicles. She also stated that Korea is planning to develop a frontal collision requirement for L7 category vehicles. The expert from EC informed GRSP that a study by the European Union on an initial assessment of additional functional safety of L7 vehicles was available. However, he added that the study did not show enough crash-worthiness data to justify an action plan. Moreover, he offered his availability, if needed, to cooperate with the expert from the Republic of Korea to adapt existing UN Regulations or in the development of a new UN Regulations to address this issue. The expert from France added that the fleet of L7 categories was increasing in his country and he volunteered to provide domestic accident data at the December 2017 session of GRSP. The Chair of GRSP, recalling a previous presentation made by the expert of his country at the May 2016 session (see GRSP-59-18) stressed the need to address the roadworthiness issue related to this category of vehicles, especially frontal collision as performed by Euro NCAP (see ECE/TRANS/WP.29/1126, para. 86). GRSP agreed to resume discussion on this issue at its December 2017 session on the basis of further research data and follow-up by WP.29 at its November 2017 session.
