According to the legislation "Limits and measurement for emissions from diesel fuelled heavy-duty vehicles (China Ⅵ)", the China Ⅵ vehicle should be equipped with remote data acquisition system, that is OBD-Ⅲ system. The current data from OBD-Ⅲ system were insufficient and could not grasp the vehicle comprehensively. The OBD-Ⅲ system of China Ⅵ heavy-duty diesel vehicle was designed and developed based on multiple information fusion. The data of sensor node, engine CAN bus and vehicle OBD diagnostic interface were all collected with multiple information fusion technology, and hence the information was more comprehensive. The data samples were preprocessed by the moving average method, and the processed results were basically consistent with the measured results of portable emission measurement system (PEMS), which had a realistic meaning to vehicle emissions monitoring for the management department.
