中文摘要：
根据发动机平均值模型,将节气门开度和点火角作为输入量,充分利用了节气门调节范围大、但响应速度慢,而点火角响应速度快、但调节范围有限的特点,结合控制量分配技术,提出了一种换挡过程的发动机转矩调节策略。在Matlab/Simulink环境下对控制器进行了仿真验证,结果表明,所提出的换挡过程发动机转矩控制策略能有效抑制输出轴的转矩波动,提高换挡舒适性。
英文摘要：
Based on engine mean value model, with throttle opening and ignition angle as inputs and fully utilizing the features of throttle opening （ wide regulation range but with slow response） and ignition angle （ quick response but with limited adjusting range）, a shift control strategy with engine torque regulation is proposed by using control allocation technique. The controller is validated by simulation with Matlab/Simulink, and the results show that the shift control strategy proposed can effectively suppress the torque fluctuation of output shaft and hence improve shift comfort.
