摘要
目的提高车辆导航精度．方法建立加速度计与里程计组合导航模型，给出相应算法及ＧＰＳ校正里程计刻度因子的方法．结果车辆运行在短时间内用加速度计与里程计组合校正里程计刻度因子，长时间运行后用ＧＰＳ校正里程计刻度因子，从而提高了车辆导航精度．结论加速度计、里程计和ＧＰＳ接收机组合导航提高了车辆导航精度，增加了系统的可靠性．
Aim To improve the precision of vehicle navigation. Methods The integrated model of accelerometer and odometer was presented, the corresponding algorithm and the method of updating the odometer′s scale factor with GPS were provided. Results After a short running, the odometer′s scale factor was updated by integrating accelerometer and odometer, after a long running the scale factor was updated by GPS and The precision of vehicle navigation was increased. Conclusion The reliability of system is improved by integrating accelerometer, odometer and GPS.
