The in-vehicle infotainment system refers to the abbreviated term for the onboard information and entertainment products installed in automobiles. Functionally, it enables information communication between humans and vehicles, as well as between vehicles and the external environment (vehicle-to-vehicle). Most in-vehicle systems are installed in the central console. Some systems integrate the main unit and screen, while others have them separated. With technological advancements, in-vehicle systems have evolved from early CD and DVD navigation to intelligent and informational developments. Currently, besides traditional features like radio, music and video playback, and navigation, modern systems include 3G and Telematics capabilities. These can integrate with the vehicle's CAN-BUS technology to facilitate communication between humans and vehicles, and between vehicles and the external environment, enhancing user experience, service, and safety-related functions. Among these features, "I-Call" and "E-Call" are the most typical examples. The "I-Call" function uses the built-in communication module in the system to connect to a backend Call-Center, providing one-touch navigation and corresponding location-based and remote services. The "E-Call" function is designed to call emergency services in the event of a severe accident. It is reported that the "E-Call" feature can read airbag information via the CAN bus and automatically dial emergency numbers. The vehicle also includes positioning and anti-theft monitoring functions. If the vehicle is stolen, the call center will collaborate with law enforcement to track its location.
