Update and Technical Challenges for European OBD Requirements
An overview of the European OBD legislation is made and the challenges imposed by the more stringent OBD requirements are identified. The available monitoring hardware options are reviewed and information is given on the different principles of operation chosen by developers. A major challenge in the Euro 6 light duty and Euro VI heavy duty vehicle OBD requirements is the detection of partial DPF failures against the upcoming particulate OBD threshold limits. The talk focuses on an extensive multi laboratory, multi sensor EU study that targeted the assessment of the technical feasibility of the proposed particulate OBD thresholds and the evaluation of the soot sensors available in the market at mature development state. In this project a test procedure was developed including test protocols and cycles, measurement equipment and artificial introduction of DPF failures. A generic OBD algorithm was also developed and calibrated for each sensor separately. The errors of omission and commission were determined for each sensor, test engine and vehicle and used as sensor evaluation score. Finally, some discussion is added from the European perspective on the US OBD requirements, certification procedures, test methods and technologies introduced by OEMs on latest vehicle models with focus on PM and NO, OTLs for Diesel passenger cars.

Worldwide OBD Update
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).

GPS and Navigation Inputs into the Control System: EU Implementing Decision 2013-529
The EU has provided a decision which allows for usage of GPS/map data in the hybrid control system for battery state of charge control. However, the decision does not provide direction on how to handle for periods when the GPS data may be too inaccurate for consumption by the control system, nor does it provide for how much diagnostic coverage is required. This presentation provides a common implementation standard to have consistent operation of these new systems, and hopefully align with any future OBD regulations which include GPS as a required input for diagnosis.
