中文摘要	干式双离合器自动变速器(DCT)的起步过程对其驾驶体验和使用寿命有很大影响;而车辆起步路况和驾驶员操作极其多样化,因此需要随之调整起步控制策略,来实现起步性能优化。该文基于车辆动力学从车速、等效坡度、路面附着和驾驶员意图4方面对起步工况进行识别,其中驾驶员意图识别结合了模糊推理模型。在起步工况识别基础上进行起步自适应控制,根据车速和路面附着选择最优的起步挡位,根据等效坡度和驾驶员意图控制双离合器的结合方式和结合速度。应用该识别方法和自适应起步控制策略进行仿真和实车测试,结果表明:车辆能有效识别不同的起步工况并采用适合该工况的起步方式,该控制策略有效提升了DCT的起步性能。; The vehicle initial acceleration process significantly influences the drivability and service life of dry dual clutch transmissions(DCT).Road conditions and driver intentions during the initial acceleration vary greatly,so flexible control strategies are needed to optimize transmission performance.The control strategies presented in this paper use the vehicle speed,equivalent slope,adhesion coefficient and driver intention with vehicle dynamic theory.The driver intention is recognized by a fuzzy logic model to give adaptive initial acceleration control strategies.The strategies decide the startup gear by considering the vehicle speed and adhesion coefficient and optimize the dual clutch control for the equivalent slope and driver intention.Finally,the recognition method and adaptive initial acceleration control strategies are evaluated to show that the vehicle can chose the best way to start for various road conditions and driver intentions that effectively improves the DCT startup performance.
