TierIIBin5 and Euro6 OBD algorithm development for Generic Diesel systems on a passenger car platform with a DOC-DPF-SCR aftertreatment.

Tasks were: legislation interpretation, advising in legislation interpretation, review of existing algorithms, algorithm development, set-up of certification process including automated process for OBD certification documentation generation, SW test and calibration work on vehicles on public roads, test tracks (internal customer (Tier I) track and Idiada), and test trips in Switzerland and Spain.

Development was mainly for diagnostic strategies on Cold Start Emission Reduction strategies and for NOx sensors.
