DGPS-Based Vehicle-to-Vehicle Cooperative Collision Warning: Engineering Feasibility Viewpoints

In this article researchers discuss an autonomous collision warning system (CWS), where information is collected and collated by a vehicle's sensors and then potential safety threats are assessed. In lieu of a centralized processing system for the proposed architecture, the authors describe a cooperative CWS (CCWS) where vehicles communicate logistical information directly to one another. Iinformation is collected by using an integrated global positioning system (GPS) and inertial navigation system (INS). The differential GPS (DGPS) suitability for CCWS as a means of future trajectory prediction for vehicle safety is assessed. Testing took into account various vehicle maneuvers as well as restrictions on DGPS coverage. Strengths of the proposed system include few missed detections, straightforward design, tolerance to data noise, and tolerance to delays. Drawbacks include potential decreased prediction accuracy, vulnerability to GPS blockages, vulnerability to shifts in driver intentions, and potential false alarm rates.
