摘　　要：针对湿式双离合器自动变速器的特点,建立起步过程动力学模型,根据车辆起步过程评价指标,得出起步过程控制策略。并结合以大众DQ250为目标变速器的起步台架试验,分析小油门平稳起步工况,验证控制方法。试验结果表明,控制策略适应拟定工况,符合车辆起步要求。Based on characteristic the wet DCT,the dynamic model of the starting process of the DCT is build.The starting control strategy of wet double clutch transmission is got,based on the evaluation of starting quality.Through the experiments on the DQ250 of VW,smooth stating of the throttle control is analyzed,and the control method is verified.It results show that the control strategy adapts to the assumed working condition and meets the requirement of vehicle starting.
