Mr. Planer presented working paper HDH-09-13. He briefly summarized the results of the TU Vienna work package and indicated that the final report would be available, soon.

Meanwhile, the final report has been published and circulated to the HDH group as working paper HDH-09-15. He then went on with the suggested validation phase 1 (pages 17 to 19).

As already introduced at the 8th HDH meeting, validation phase 1 is intended to verify the suggested changes of the research institutes to the Japanese HILS method. The proposal is based on the ECU as software in the loop as basis for further programming and software development. As task 1, a serial hybrid simulator would be developed, since the ECU is considered easier to implement. The simulator would cover both the WHVC and the WHDHC as input cycles for the simulation, and would be extended with a library for non-electric components, a library of new components, such as planetary gear box, power split, and with thermal models (exhaust gas aftertreatment components, coolant, lube oil, battery and electric motor). Task 2 would adapt the simulator to a parallel hybrid. As a result of tasks 1 and 2, task 3 would consist of amendments to the Japanese procedure with respect to the methods for component testing, test cycle definition and the simulation method. In task 4, an interface system would be defined to be used for real ECUs.

The participants principally agreed to the proposal. It was common understanding that starting with the serial hybrid would be most beneficial. JARI indicated that they had completed a serial hybrid model, which would be made available to TU Vienna for the validation study. JARI further informed that they already have a simple serial hybrid ECU and would support TU Vienna in developing the software ECU. OICA agreed to deliver input to task 1.4.

OICA offered to sponsor at least part of validation phase 1 depending on the total budget needed. The secretary asked the participants to consider contributing to the validation. In order to get a clearer picture, Mr. Planer was asked to submit a quote to the secretary by mid-April. Task 6 on page 19 (real vehicle testing) of working paper HDH-09-13 is not considered part of validation phase 1, but validation phase 2 and should therefore not be part of the quote. In order to meet the revised project plan the program should start no later than June 2012. Final approval of validation phase 1 will be on the agenda for the 10th HDH meeting.

Mr. Martinez indicated that EU COM would most likely take over the budget for validation phase 2. Intention would be to run this validation at JRC. OICA will check by the 11th HDH meeting (October 2012) which HDVs could be offered for this validation. It is expected to run at least one parallel and one serial hybrid.
