摘　　要：双离合器自动变速器以其特有的结构特点,使车辆具有良好的动力性、燃油经济性以及驾驶舒适性,成为目前自动变速器领域应用的新动向。在研究双离合器自动变速器起步控制理论的基础上,将起步分为5个主动控制过程阶段,并给出相应的车辆动力计算。通过对所设计的起步控制策略进行实车测试,证明该起步控制策略能有效实现双离合器自动变速器的起步而且在起步平顺性上也取得了很好的效果。With unique configuration characteristic,the dual- clutch transmission（ DCT） makes the vehicle get a good result in power performance,fuel economy and drivability,and recently it becomes a new development trend in the field of transmission. Basing on analysis of launch control theory of DCT,five phases about launch active control are proposed and vehicle power calculations corresponding to those each control phase are also proposed. It proves that this control strategy can make the vehicle launch in effect and also get a good result of drivability through the test according to the design.
