Feasibility assessment regarding the development of VECTO for hybrid heavy-duty vehicles
Final report
Publication metadata
The computer simulation tool, VECTO, used to calculate CO2 emissions from new heavy-duty vehicles to be certified, reported and monitored in the European Union mandatory from 1.1.2018 on. In its current version, VECTO does not have the capability to simulate hybrid powertrains. This represents a clear limitation of the entire approach because it would leave a significant and increasing share of new HDVs, in particular city buses where the technology is more spread, without a certified fuel consumption value. In addition, this could lead to a potential market distortion because if they cannot be compared in a mandatory EU certification procedure with the other HDVs in terms of fuel consumption and CO2 emissions, the introduction of hybrid powertrains might be disincentivized. The aim of this study was to assess the current situation and to propose technical solutions for the extension of the HDV CO2 certification procedure to include hybrid powertrain configurations. Therefore, relevant powertrain configurations to be considered shall be derived from the assessment of hybrid technologies –existing or under development- at OEM level. One obvious strategy is to extend VECTO so as to inherently support hybrids. Independently of assessing the feasibility of extending VECTO, due to the intrinsic complexity of the issue and the potential costs involved, the study should also identify possible alternative approaches beyond the use of VECTO but still showing a good correlation with VECTO results. For the detailed analysis of possible options the following 5 tasks were performed for the purposes of this study: 1) Assessment of the current status regarding hybrid powertrains at OEM level 2) Review of the methodologies and tools used or planned to be used for hybrid HDV certification in other global markets 3) Identification and description of possible options for the extension of VECTO to simulate hybrid HDVs 4) Identification of alternative options for certifying hybrid HDVs 5) Assessment and comparison of all suggested approaches for certifying fuel consumption and CO2 emissions of hybrid HDVs
