摘　　要：DCT同步器换档控制是DCT控制的关键技术之一。如何确保DCT挂档迅速,换档冲击小、异响小,避免打齿、挂档失败,这对于DCT的控制意义非常重大。文章对同步器换档过程进行细分,并依据同步器换挡过程的不同阶段提出其所需控制原理。基于该控制原理提出了换档过程各个关键阶段/点所需换档力的计算及控制方法和换档速度测试及控制方法。最后通过将该换档过程控制原理及计算/测量方法在某款车型匹配DCT的某档位进行计算分析和试验验证,证明控制方法的有效性、合理性。Synchronizer shifting control is one of the key technology of DCT control.It is very important for DCT how to insure the shifting function, meanwhile to reduce the shifting impact and sound, toavoid clash and dropping gear.This article subdivides synchronizer gear shifting process and describes the control principle on the basis of synchronizer shifting at different stages of the process. It represents every key stage, shifting force calculation on various key points, shifting speed test and control method based on this principle. Finally, this shift process control/measurement principle and calculation methods are test in a certain DCT gear, and proved its validity and rationality.
