2. pilot phase - Learnings
TF6 – General comments, certification procedure
Important parts of the regulation are missing, parts that are needed before providing final evaluation / comments, e.g.:
Detailed provision for input data certification are still unknown regarding:
Families and type definitions
CoP provisions
Requirements for documentation
Provisions for tyre RRC for CO2 calculation is missing
Provisions for the CO2 calculation process approval are missing
Provisions for the “Ex-post verification” are missing
The SiCo test is an “ex-post verification” test, not considered as a COP test
Provisions on data format to be stored, data files handling, record keeping etc. are missing

3. pilot phase - Learnings
TF6 – General comments, certification procedure
The option to apply for a separate certificate for retarders, or for torque converters (in case of automatic transmissions ), is requested
The use of correct technology default values for Auxiliaries should be included in the certification of the CO2 calculation process. A separate certificate for Auxiliaries is not needed.
The text of the Technical Annex needs to be further clarified
The management of default values has to be defined
The appropriate definition of the “certified input data” should be discussed, whether it is the raw data submitted to the pre-tools or the resulting input data to VECTO?
The appropriate information to include in the information document should be reviewed
Non-essential information shall be removed. For instance , “any elements of design that affects CO2” is a too extreme description. It should be limited to “main elements”.
Proposal to shift test results from information document to test report.

4. pilot phase - Learnings
TF6 – General comments, certification procedure
The family concepts shall include the possibility to test more, if the OEM wants, without creating too many families (provided that the test accuracy allows for this)
The legal status and responsibilities regarding updates, malfunctions, etc. of the software tools provided by the Commission (VECTO and pre-tools) must be clearly defined in the regulation
The approval of the CO2 calculation process must be independent of the VECTO version used
The CO2 calculation process approval should be the requirement for the Whole Vehicle Type Approval (WVTA). Component /subsystem approvals shall not be listed for WVTA
The component manufacture of must be responsible for providing the data, defining tolerances and ensuring Conformity of Production regarding all input data for VECTO, including tyre RRC
