Improvement in OBD Development Process for HEV's

Hybrid technology has the potential to enable dramatic reductions in greenhouse gases (GHG), such as the California goal of reducing GHG by 80 percent from 1990 levels by 2050. As a result it is expected that hybrid systems will occupy a growing proportion of the market. ...In this presentation, Ricardo will present a process for evaluating the impact that a hybrid system which has been optimised to minimise GHG emission over a specified drive-cycle will have on the effectiveness of engine OBD monitors. ...The optimisation process generates torque split, mode and gear changes required to minimise GHG emissions. This optimal engine-transmission-machine on-time profile is automatically analysed to generate the impact on the engine OBD system.
