Powertrain Systems development is facing unprecedented challenges driven by the convergence of many factors: increasing government regulations for tailpipe emissions, diagnostics and fuel economy, increased competition, shorter development cycles, and tighter program budgets. Using telematics and information technology to automate the evaluation of a system�s robustness enables engineers to focus their time on problem areas during their normal development process and launch with quality. This presentation will use real world examples to detail how this methodology was jointly applied by Control-Tec and Ford Motor Company to identify and improve the system performance of Ford�s Air-Fuel Imbalance Monitor before production. Presenter Bill Leisenring, Control-Tec LLC

OBD system requirements were first developed by the California Air Resources Board, the U.S. Environmental Protection Agency, and the European Commission. New OBD requirements should be as consistent as possible with existing requirements to maximize reliability and to minimize system complexity, proliferation of configurations, and consumer cost. New OBD requirements from around the world are briefly reviewed and most are consistent with the original U.S. and European requirements. Worldwide OBD requirements are being further harmonized under the United Nations, Economic Commission for Europe, World Forum for Harmonization of Vehicle Regulations (WP29). Presenter David H. Ferris, General Motors Company

Plug-in Hybrid Electric Vehicles (PHEVs) are entering the market and bring with them new OBD issues. A key one is how to measure in-use monitor performance ratio and where to set a standard for this, as PHEVs will have varying amounts of engine-on operation depending on customer plug-in and driving behavior. Toyota�s Prius PHEV system is described and customer use data from a US demonstration fleet is examined. Some prior denominator proposals by Toyota and CARB are explained, as background for the current CARB/industry agreement for denominator and ratio. Presenter Morton M. Smith, Toyota
