Discussion of vehicle characteristics to be taken into account (or left out) in order to ensure an optimally harmonized set of heavy-duty vehicle test procedures for worldwide use.
Mr. Danczyk presented the OICA proposal for vehicle parameters for the HILS modelling. Background for the proposal are the different vehicle categories in the regional legislation of the Contracting Parties. The vehicle parameters under consideration are summarized on page 4. For the driving resistance parameters (test vehicle weight, curb weight, rolling resistance, air resistance), calculation formulae based on engine power are being proposed. Ratio related parameters, losses and inertia moments would be based on OEM specific values.
The proposal was agreed by the Group. The institutes were asked to integrate the equations into the models.
