Mr. Berg presented OICA’s input. He indicated that the OICA members continue to support the validation test program 1 with the required inputs for the signal list and the component list. In addition, at least two vehicles will be made available for validation test program 2. In OICA’s opinion, both WHVC and WHTC curves need signal filtering in order to remove artifacts due to gear shifting events that are neither representative for a HV nor suitable for simulation. For the WHVC motorway phase, introduction of road gradients is proposed. As regards the WHDHC approach, the vehicle speed signal will likely be needed by the ECU (either from WHVC or backwards calculation). |
