Performance evaluation of a vehicular edge device for customer feedback in Industry 4.0

Abstract

<p>Industry 4.0 is the term used to specify the current industrial revolution, not only from a technological point of view but also from economical, sociological and strategical points of view. The revolution involves several traditional economic sectors, as is the case with the industrial ecosystem. The main benefits are related to creating value during the entire product lifecycle and in terms of customer feedback, which is particularly relevant to the automotive industry. Its disruptive diffusion is due to various enabling technologies, such as the Internet of Things (IoT), and, as such, it is a vision rather than a technological step forward. Thus, this paper investigates a performance evaluation of an Edge OBD-II device, which collects data from vehicles in an autonomous way in order to provide customer feedback and tracking. The metrics evaluated were different sets of OBD-II Parameter IDs (PIDS), responsiveness, driver behaviour and CO<sub>2</sub> pollution estimates. The experiments were performed using three vehicles in urban and highway areas in the city of Natal, Brazil. For validation purposes, the results obtained from the vehicles were compared with an OBD-II Emulator, which demonstrated the accuracy of the experiments.</p>

A TinyML Soft-Sensor Approach for Low-Cost Detection and Monitoring of Vehicular Emissions

“…Considering the characteristics of the selected vehicle, with only the PID MAF available, the calculation of CO 2 emissions expelled by the vehicle was based on Equation ( 10 ). Actually, the compatibility of the CO 2 calculation using MAP or MAF has already been verified in a previous work by the authors of this article, as seen in [ 43 ], which reinforces the relevance of the achieved results in this section.…”

“…Thus, when programming the proposed soft-sensor approach, if the considered vehicle has both sensors (MAP and MAF), the emission of CO 2 is calculated directly by exploiting the MAF provided by the OBD-II reader, saving resources and computing time. Actually, according to [ 43 ], emissions being calculated through the PID MAP or the PID MAF present similar values; thus, they could be adopted interchangeably.…”
