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。
Double clutch automatic transmission with its unique structural characteristics, so that the vehicle has good power, fuel economy and driving comfort, become the new trend of the application of automatic transmission field. Based on the research of the starting control theory of dual clutch automatic transmission, the starting process is divided into five stages of active control and the corresponding vehicle dynamics calculation is given. The test of starting control strategy is carried out in real vehicles, which proves that the starting control strategy can effectively start the dual clutch automatic transmission and has good effect on the starting ride comfort.
