| 摘 要： | 通过对车载导航系统结构、功能的分析，对车辆的高精度导航定位进行了研究。在常见的卫星导航（GPS）、航位推算（DR）等导航定位的基础上，进一步研究并实现了地图匹配算法，克服了GPS信号受阻时定位间断或失效的缺点，避免了航位推算定位误差随时间的积累。通过大量的跑车试验表明，基于GPS／DR／MM的车辆导航系统，可以高精度地实现车辆定位，进而可以实现地理信息的查询、交通诱导等功能。具有重要的实际应用价值。 |

| Abstract: | The paper discusses high precision positioning and navigation by analyzing the structure and functions of vehicle navigation system. It further studies and implements map matching algorithm in the system based on GPS and Dead Reckoning, and not only overcomes shortcomings such as disconnection and invalidity of GPS, but also avoids the accumulation of navigation location calculation errors with time passing. Many field trials for principle prototypes are made and the experimental results show that the system can be steadily and reliably run on vehicle, providing geographic information searching and navigation function, and proves to be effective and feasible. |
