Division ‘Appendix 3a Extended Documentation Package
United Kingdom
The extended documentation package shall include the following information on all AES:
- (a)
a declaration of the manufacturer that the vehicle does not contain any defeat device not covered by one of the exceptions in Article 5(2) of Regulation (EC) No 715/2007;
- (b)
a description of the engine and the emission control strategies and devices employed, whether software or hardware, and any condition(s) under which the strategies and devices will not operate as they do during testing for TA;
- (c)
a declaration of the software versions used to control these AES/BES, including the appropriate checksums of these software versions and instructions to the authority on how to read the checksums; the declaration shall be updated and sent to the Type Approval Authority that holds this extended documentation package each time there is a new software version that has an impact to the AES/BES;
- (d)
detailed technical reasoning of any AES; including explanations on why any of the exception clauses from the defeat device prohibition in Article 5(2) of Regulation (EC) No 715/2007 apply, where applicable; including hardware element(s) that need to be protected by the AES, if applicable; and/or proof of sudden and irreparable engine damage that cannot be prevented by regular maintenance and would occur in the absence of the AES along with a risk assessment estimating the risk with the AES and without it; reasoned explanation on why there is a need to use an AES for starting the engine;
- (e)
a description of the fuel system control logic, timing strategies and switch points during all modes of operation;
- (f)
a description of the hierarchical relations among the AES (i.e., when more than one AES can be active concurrently, an indication of which AES is primary in responding, the method by which strategies interact, including data flow diagrams and decision logic and how does the hierarchy assure emissions from all AES are controlled to the lowest practical level;
- (g)
a list of parameters which are measured and/or calculated by the AES, along with the purpose of every parameter measured and/or calculated and how each of those parameters relates to engine damage; including the method of calculation and how well these calculated parameters correlate with the true state of the parameter being controlled and any resulting tolerance or factor of safety incorporated into the analysis;
- (h)
a list of engine/emission control parameters which are modulated as a function of the measured or calculated parameter(s) and the range of modulation for each engine/emission control parameter; along with the relationship between engine/emission control parameters and measured or calculated parameters;
- (i)
an evaluation of how the AES will control real-driving emissions to the lowest practical level, including a detailed analysis of the expected increase of total regulated pollutants and CO2 emissions by using the AES, compared to the BES.’.
