Modular Integration of Entertainment Hardware in Automotive Systems

This document outlines the modular design and integration of individual hardware components in automotive entertainment systems, such as radio receivers, CD players, and Bluetooth connections. It emphasizes the role of drivers that feed applications, presenting a user interface that ties them together. The paper discusses the hardware abstraction layer (HAL) as an API that simplifies software communication with diverse hardware, enabling commoditization. Furthermore, it delves into the applications of sensors, telematics, and health monitoring within these integrated systems.

  2. Decompose • Integrate • Individual hardware pieces are associated with drivers • The drivers feed applications • The applications are tied together by a user interface

  3. Decompose into modules PlayList Radio CD Player DVD Player Speakers CD Driver BlueTooth USB OS/Hardware

  4. Entertainment • Radio receiver • Regular radio • Satellite radio • Antennas • Radio • OnStar • OnStar • CD player • DVD player • Sound • Stereo speakers • SurroundSound • Displays • Touch • Non-touch • Games

  5. Information/Telematics • Sensors/Radar • Vehicle health • Cell phone connections • Apps

  6. Hardware abstraction layer • The specific hardware is hidden from the software. • The layer acts as an API • An operating system usually includes a layer • Making the API from standards allows the underlying device to be commoditized
