Progress report of the working group developing the emissions and CO2 test procedure for heavy-duty hybrid vehicles.

Assessment of hardware-in-the-loop simulation (HILS) methodologies and proposals for enhancements (e.g. more topologies, component library, temperature signals to include cold start tests).

Work package 3: Extension of hardware-in-the-loop simulation (HILS) to non-electrical hybrids currently not
covered by Kokujikan No. 281.

Summary report (identical to document HDH-10-03) on the assessment of the hardware-in-the-loop simulation (HILS) methodology for heavy-duty hybrid emissions proposed by Japan.

Proposal from the research institutions involved in assessing and adapting hardware-in-the-loop simulation (HILS) methodologies to the evaluation of heavy-duty hybrids for the anticipated second phase work to produce a HILS tool for use in GTR 4 hybrid vehicle provisions.

Status of the work towards developing a methodology for certifying heavy-duty hybrids based on “hardware in the loop simulation” (HILS).

Status of the work towards developing a methodology for certifying heavy-duty hybrids based on “hardware in the loop simulation” (HILS).

Update on development and validation of the new hybrid heavy-duty vehicle test cycles.

This report is the final report of the work done by the Universities of Technology in Chalmers, Graz and Vienna and research institute TNO performed within the research program on an emissions and CO2 test procedure for Heavy Duty Hybrids (HDH). This report specifically refers to Validation Test Program 1 (VTP1) under the contract for “Developing the Methodology for Certifying Heavy-Duty Hybrids based on HILS”.

Presentation of the results of the validation test program 1 and status of test program 2 (Chassis dyno test program at JRC, HDH drive cycle investigation, and HILS/SILS model verification) and review of open issues for drafting the GTR text.

Status report on research and validation programs concerning:

• HILS Model Library
• WHVC Test Cycle
• System Work Concept
• Rated Power Determination for a Hybrid Vehicle
• Family Concept-Validity of Certification
• Validation Test Phase 2 (VTP2) Validation Results−Sub-presentations of VOLVO, MAN and IVECO
• VTP2 conclusions & discussion of further actions

Revised version of the additional slides concerning the seat performance criteria for rear-impact testing presented during the session.

Presentation on urban noise research at Chalmers University.
