Abstract
Vehicular applications are the bases of vehicle value-added services in the future, which depend on real-time access to multi-source vehicular information. In order to be applied to vehicles in use easily, the implementation of vehicular applications should avoid modifying vehicles and control the increase of wiring harness to decrease system complexity. A vehicular information real-time monitoring framework is proposed, which can collect, transfer and display vehicle driving information, such as velocity and trouble codes, and environment information, such as GPS and video around the car. A flexible and reliable communication protocol is designed to exchange multi-source information between modules in the framework. On-Board Diagnose (OBD) technology and wireless technology are used to collect vehicle driving information to avoid modifying vehicles, and to transfer information to control the increase of wiring harness, respectively. The prototype system is tested on a car, and the results show that the system can be used easily as a basis for future vehicular applications based on multi-source information fusion.
