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.

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.

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.

Progress report on the effort to establish provisions for heavy-duty hybrid vehicles in GTR No. 4, prepared for presentation to the June session of the Working Party on Pollution and Energy (GRPE).
