Machine Learning, IoT, and Embedded Systems for Intelligent Automotive Diagnostics, Predictive Analytics, and Smart Mobility Systems

Abstract

The convergence of Machine Learning (ML), Internet of Things (IoT), and Embedded Systems is redefining the automotive ecosystem across Electric Vehicles (EVs), Hybrid Electric Vehicles (HEVs), and Internal Combustion Engine (ICE) platforms. Modern vehicles are equipped with hundreds of sensors and Electronic Control Units (ECUs), generating high-frequency, multi-dimensional data streams. These data streams, accessed via OBD-II and CAN bus, provide a foundation for predictive analytics, anomaly detection, and intelligent decision-making.

This paper presents a comprehensive, end-to-end framework for designing, implementing, and scaling ML-enabled automotive diagnostic systems using embedded platforms and IoT infrastructure. It integrates insights from TinyML, modern ML frameworks, and real-world automotive applications such as EV battery health monitoring, hybrid system optimization, and ICE predictive maintenance.

Furthermore, the paper highlights how KeenComputer.com and IAS-Research.com can support SMEs and enterprises in deploying scalable, cost-effective, and intelligent automotive solutions.
