The Internet of Vehicles (IoV): Connecting Cars to the Digital World
Introduction
The digital transformation of the automotive industry has advanced beyond onboard electronics and infotainment systems to a larger, more integrated ecosystem known as the Internet of Vehicles (IoV). A natural evolution of the Internet of Things (IoT), IoV connects vehicles to networks, infrastructures, cloud platforms, and even each other, creating a seamless web of data exchange and communication.
The IoV paradigm is transforming cars from isolated machines into intelligent, communicative entities capable of making decisions, anticipating issues, enhancing driver safety, and participating in a smart transportation ecosystem. With connected cars projected to make up over 95% of all new vehicles sold globally by the early 2030s, understanding IoV is crucial to grasping the future of mobility.
This article delves deeply into the concept of the Internet of Vehicles, its components, benefits, underlying technologies, applications, challenges, and its role in shaping the digital mobility of tomorrow.
