摘要
为解决自主导航智能车辆纵向精确定位的问题,设计了一个基于两维磁阻传感器的车辆局部定位系统,包括横、纵向磁定位方法的确定、磁尺结构设计和磁信号采集处理的软硬件设计。进行了磁钉的两维磁场信号采集和磁定位方法的对比验证,结果表明:该系统不仅在较大范围内具有高的横向定位精度,还能够提供精确的纵向定位信息。
To solve the problem of precise longitudinal localization for autonomous navigating intelligent vehicles, a vehicle localization system based on 2-axis magneto-resistive sensor was designed, which included the lateral and longitudinal localization method, the design of structure for magnetic sensor ruler, and the hardware and software design for the collection and processing of magnetic signals. With the experiments on the 2-axis magnetic field collection for the magnetic marker and the comparison of different magnetic localization methods, this system can get precise lateral and especially longitudinal localization measurement in a large range.
