摘　　要：针对由于磨损导致的同步点发生变化,综合考虑了同步器错位的现象,分析了同步器错位出现的原因及其与换挡同步力之间的关系,进而开发了一种新的同步点辨识方法。最后通过实车实验证明了该同步点辨识方法在升档和降档时都有着较好的表现,辨识到的同步点的准确性和一致性较好。Aiming at addressing the changing issue of synchronization position caused by wear, this paper considers the dislocation between the sleeve displacement and sensor, the cause of dislocation and the relationship between dislcation and gearshift force is analyzed. Then this paper develops a noval estimation method of synchronization position. Finally experimental results have demonstrated that the estimation method has good performance and the estimated synchronization positions have good accuracy and consistency.
