磁阻罗盘及其在车辆导航中的应用

Application of Magnetoresistive Compass in the Navigation of Vehicles

介绍了以磁阻传感器为基础的磁阻罗盘HMR30 0 0的硬件组成、软件设计原理及其在车辆导航中的应用。重点叙述了在车体倾斜和有金属材料影响的情况下 。

The hardware structure and the software designing principle of the magnetoresistive compass (MM) based on the magnetoresistive sensor and its application in the navigation of vehicles are expounded,and these methods of compensating and computing to the magnetoresistive sensor's output are introduced mainly when the bodywork is tilt and there is the influence of metal materials.
