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.
