Progress report and overview of the effort to develop a heavy-duty hybrid vehicle emissions test procedure based on hardware-in-the-loop simulations.

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).

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.

Overview of TU Graz and TNO evaluation of hardware-in-the-loop simulation methodologies covering the test cycle and vehicle related parameters, harmonisation with CO2 test methods, inclusion of power take-off, and worldwide harmonized vehicle cycle weighting factors.

Presentation on the pilot test phase to evaluate the draft type-approval test procedure for the assessment of mobile air-conditioning (MAC) energy efficiency developed by the consortium of TUG, LAT, KTI and TNO.

TNO presentation on the results of its simulation of a retrofit selective catalytic reduction system.
