    摘要:

    针对以液力变矩器为起步装置,金属带无级变速传动为高速行驶时调速装置的双状态无级变速汽车,在发动机和液力变矩器台架实验基础上,建立了用变矩器作起步装置的双状态无级变速传动系统动力学模型,提出了双状态无级变速汽车起步控制策略.仿真结果表明,所提出的控制策略能明显改善对车辆的动力性能.研究结果为开发设计双状态无级变速汽车提供理论依据.

    Abstract:

    Continuously variable transmission (CVT) is the ideal transmission for automobile, it is also one of the most important research items of researchers and automobile companies all over the world. The dynamic simulation model is established and integrated control strategy of standing start is proposed for dual mode CVT vehicle, aiming at automatic vehicle with torque converter as a starter and metal pushing belt as a higher transmission equipment (Dual mode CVT vehicle), on the base of engine and torque converter performance experiment. Simulation result shows that vehicle performance can be improved by using the control strategy proposed. The research results provide the theory method of analyzing and designing for CVT vehicle.
