Relative position measurement using Differential Global Positioning System (DGPS) and inter-vehicle communication is proposed and evaluated. Relative position information of neighboring vehicles is expected to enhance Advanced Vehicle Control and Safety Systems (AVCSS) and to improve reliability of sensor information such as inter-vehicle distance. This paper proposes a method of acquisition of relative position information sufficiently accurate in real-time to be used for the above application. The proposed method is evaluated by experiments using two vehicles. Experimental results show that the proposed method makes it possible to acquire accurate and latency-compensated information in a short sampling period.
