Abstract: A system and method to rapidly perform emissions measurements of in-use vehicles being driven by the general public under normal driving use for determining whether the vehicles are performing in accordance to the regulatory standards by which they were certified. The system and method require no recruitment testing of in-use vehicles with potentially detectable connections, but instead incorporate a vehicle emissions remote sensing device that does not require mechanical or electrical connection to the vehicle, with the measured values being recorded and the vehicles identified, including based on, for example, make and model, engine size, engine combustion management technology and/or pollution control technology.

Abstract: A system and method to rapidly perform emissions measurements of in-use vehicles being driven by the general public for comparison with vehicle inspection OBD emission fault code testing results for determining if the inspection results indicate that false failures are being generated for a particular vehicle group, such as based on make and model, engine size, engine combustion management technology and/or pollution control technology, or determining if the inspection results correlate with increased in-use emissions. The system may access or integrate with a database of vehicle inspection OBD emission fault code testing results that may be analyzed to evaluate the existence of higher than normal or expected OBD failure rates for emissions related items. The system and method require no recruitment testing of in-use vehicles with potentially detectable connections, but instead incorporate a vehicle emissions remote sensing device that does not require mechanical or electrical connection to the vehicle.
