【摘要】 针对GPS测量实际道路车速中存在的突变野值问题,提出改进的自适应"当前"统计模型.该模型在"当前"统计模型基础之上,根据新息向量实时对机动频率做两次调整.两次调整算法使得模型更加适应于跟踪快速机动目标,提高跟踪精度.最后将模型应用于处理GPS测量的实际道路行驶车速,同时与通过CAN总线采集的车速传感器信号进行对比.实验结果表明该方法能够改善测量结果,使修正后的数据更加切合实际.更多还原

【Abstract】 For correcting outliers emerging in GPS measurement data of real-riving speed,an improved current statistical model is proposed.The model adjusts maneuvering frequency twice according to innovation vectors,and the method makes more suitable to track fast maneuverable target and improve,tracking precision.By comparing the data measured by GPS on a real-road conditions using the model with the data from a CAN bus of the vehicle,it is found that the model can effectively improve the measurement results and obtain more reliable data.更多还原
