Software Interfaces for In-Vehicle Navigation and Information Systems

Modern in-vehicle navigation and driver information systems are used to track the location of vehicles, locate destinations by street address, and provide guidance to drivers. A typical system consists of a general-purpose computing device, sensors, mass storage, and applications software. The optimum configuration of such a system is as a set of separate modules of software that provide certain well defined services through well-defined interfaces. This configuration allows applications software to be independently developed, and allows applications software to run on a variety of hardware.
