Collaborative Driving Support Systems

Paper Summary:

This paper investigates the challenges and feasibility of developing intelligent driving system providing time-sensitive information about traffic conditions and roadside facilities. The architecture for collaborative vehicle communication system is presented using the concepts of wireless networks and Bluetooth protocol. The paper further describes how vehicles can form mobile ad-hoc networks and exchange data through the on-board Bluetooth sensors and analyzes the key design concepts of the intelligent driving service infrastructure. The paper indicates that the collaborative fusion of multiple positional data can give a better understanding of the surrounding traffic conditions for collaborative driving. The technical feasibility of using Bluetooth for data exchange among moving vehicles is evaluated. Includes color illustrations and charts.

From the Paper:

"Vehicles participating in the service infrastructure are equipped with an embedded microprocessor with a display interface, a GPS receiver, a class 1 Bluetooth sensor node, and an onboard diagnostics (ODI) interface. Some vehicles may have alternative wireless network connectivity support based on an on-board cellular communication device. The ODI is used to acquire a small set of data values from mechanical and electronic sensors mounted on the vehicle. All subsystems (GPS, ODI, wireless networking and Bluetooth links) are connected and forward data to the embedded microprocessor."
