摘　　要：建立了DCT双离合器联合起步的数学模型,基于发动机恒转速控制策略,以磨滑功为目标,制定了以一挡和二挡起步的转矩控制策略。仿真结果验证,所提出的控制策略能很好地使两离合器分担磨滑功,延长离合器使用寿命。DCT launching model with two clutches working together was built. On the basis of fixed engine speed, considering the slipping friction work as target,the control strategy of torque transfer for 1 st gear launch and 2 nd gear launch was proposed. The simulation result shows that the strategy proposed could let two clutches share slipping friction work, and prolong the life-span of clutches.
