摘　　要：常见的车载GPS导航定位技术由于市区内建筑遮挡等情况会导致一定时间内无法定位。故对GPS/DR组合导航技术加以研究,给出对应系统模型及算法,并采用地图匹配修正技术后,使得定位精度持续稳定,并可进一步作为自动驾驶系统构件。研究表明,该方案效果显著,工程上可行。GPS is widely used in car navigation system for portable navigation devices and car telematics applications. The navigation results are not available in GPS signal blockage area, such as urban canyons, tunnel and underground parking area. Designs a GPS/DR integrated naviga- tion system to provide continuous positioning, Simultaneously, employs a map matching algorithm which enhances the calibration accuracy of gyroscope and gives a better estimation of position. The system accuracy performance is investigated using field tests in many urban envi- ronments. The test results show that the GPS/DR/MM system works well even when GPS signals are not available.
