摘　　要：DCT同步器换挡控制是DCT控制的关键技术之一。如何既保证正常挂挡,又能减小换挡冲击,无误挂挡、自动脱挡对于DCT的控制意义重大。文中从分析湿式DCT同步器的特点入手,针对不同阶段的需求提出控制方法,建立整车物理仿真模型,并通过仿真分析和整车试验验证证明控制方法的有效性、合理性。此外,同步器的控制还受到整车状态、工作温度、驾驶意图变化等方面的影响,是一个复杂的过程。Synchronizer shifting control is one of the key DCT control technologies. It is very important for DCT to ensure the shifting function and reduce the shifting impact. This paper analyzes the feature of synchronizer shifting in wet DCT, and proposes the control method corresponding to each shifting phase. Vehicle plant simulation model is built. Then the effectiveness and the rationality of this control method is proven by simulation and vehicle tests. The synchronizer control is a complex process which will be affected by vehicle status, working temperature and driver＇s intended action and so on.
