摘　　要：车载组合定位是现代汽车常用的定位方式,它通过集成化的传感器及卫星定位系统,实时定位车辆位置,在现代错综复杂的城市交通中有着广泛的应用.本文以微小型车载组合定位系统为对象,设计了基于ARM嵌入式系统的微小型车载组合定位系统,借助MEMS传感器设计的惯性导航系统、GPS导航及相应的融合算法,实现对车辆的实时高精度的定位.Vehicle Integrated Position is an effective method for modern positioning system. It provides the real-time and accurate position for cars with the help of integrated sensors and global positioning system. Thus, ithas been widely used in the intricate urban transport. In this paper, in order to improve the positioning accuracyof the Vehicle Integrated Positioning System, an ARM-based miniature Vehicle Integrated Positioning Systemwas designed, which is based on MEMS inertial sensors and GPS. Besides, some infusion algorithms were designed for the Vehicle Integrated Positioning System, which improves the accuracy of the designed system.
