双离合器自动变速器（Double Clutch Transmission，简称 DCT）因其作为当前世界最前沿的变速器产品，对手动变速器结构上的继承性好，机械效率高，适用范围广，已成为各汽车企业争相研究开发的焦点。研究双离合器自动变速器的核心技术对我国自主开发自动变速器产品具有重要的现实意义。 换挡规律是自动换挡时刻随控制参数变化的规律，是双离合器自动变速器换挡控制系统的核心。由于传统换挡规律不能充分反映车辆发动机的动态特性,没有充分考虑车辆载荷变化、驾驶员操纵意图和道路环境对换挡控制策略的影响，使得双离合器自动变速器的性能难以得到充分发挥。 基于以上背景，本文首先分析以及简化了车辆的运动及动力传递线路，利用AMESim软件建立了整车模型、DCT动力学模型以及离合器控制模型。在分析现有换挡控制策略的基础上，根据DCT结构和控制原理，利用模糊逻辑控制方法，以车速、油门开度、加速度为换挡控制参数制定了模糊三参数换挡控制策略。基于模糊三参数换挡控制策略，同时考虑质量因素以及油门开度变化率因素对换挡控制策略的影响，制定了两种四参数换挡控制策略（一种是考虑质量因素的模糊四参数换挡控制策略，另一种是考虑油门开度变化率因素的模糊四参数换挡控制策略）和模糊五参数换挡控制策略。以上四种模糊换挡控制策略都利用AMESim和MATLAB/SIMULINK联合仿真平台进行仿真实验，验证了其有效性及合理性。

As the world's most cutting-edge transmission products ,Dual Clutch Transmission (referred to as DCT)that inheritances on the manual transmission in the structure , has high mechanical efficiency and widely applied , has become the auto companies competing research and development focus. It is has important practical significance for China's own development of automatic transmission products that research dual clutch transmission core technology.   Shift schedule refers to the time between two automatic shift gears with the variation of the control parameters.Shift schedule is core technology to dual clutch transmission shift control system . Because of the traditional shift schedule does not adequately reflect the dynamic characteristics of the vehicle engine , does not fully consider the affect that the vehicle load changes , the driver meaning and the road environment to the shift schedule, making the performance of dual clutch transmission is difficult to be fully realized.   Based on the above background , in this paper , the movement of vehicles and power transmission lines are analyzed and simplified ,the vehicle model and clutch dynamics and control model are built by AMESim software.With the existing shift control strategies are analyzed,the fuzzy three-parameter shift control strategy is made ,which according to DCT structure and control principles and the using the method of fuzzy control logic and speed , throttle , acceleration as the control parameters. Based on fuzzy three-parameter shift control strategy , two kinds of fuzzy four-parameter and the fuzzy five-parameter shift control strategy are developed ,which taking into account the affecting factors of the vehicle quality and rate of change throttle.These four kind of strategies are verified by AMESim and MATLAB / SIMULINK co-simulation platform for its validity and reasonableness.
