提出了一种多车辆协同定位系统，该系统利用GPS接收机和测距传感器协同标定车辆位置并识别周围车辆。所提出的系统以分布式方式操作，并且即使附近的所有车辆不参与或不能参与系统也能工作。每个车辆根据信息的来源和新近度获取具有不同精度的各种定位信息，并基于从估计精度导出的似然性来编译它们，以使估计误差最小化。基于仿真的性能评估表明，该系统的估计精度提高了85%，平均相对于独立的GPS接收机，并认识到约70%的周围车辆的误差为1米。
This paper presents a vehicular positioning system in which multiple vehicles cooperatively calibrate their positions and recognize surrounding vehicles with their GPS receivers and ranging sensors. The proposed system operates in a distributed manner and works even if all vehicles nearby do not or cannot participate in the system. Each vehicle acquires various pieces of positioning information with different degrees of accuracies depending on the sources and recency of information, and compiles them based on likelihood derived from estimated accuracies to minimize estimation errors. A simulation based performance evaluation given in the paper shows that the proposed system improves the estimation accuracy by 85% on average with respect to the standalone GPS receiver, and recognizes about 70% surrounding vehicles with an error of 1m.
