Abstract: In this study, a shift control algorithm for improving the shift quality of a parallel hybrid drivetrain with an automated manual transmission (AMT) is proposed. The general AMT requires sophisticated control of clutch in clutch engagement to improve its shift characteristics, and that is generally known to be difficult. But in this hybrid drivetrain, we can control the speeds of clutch plates by engine and motor control and it provides the easier clutch control in shift process than general AMT. Additionally, it permits much-reduced shift shock. The motor control during the shift period also enables the velocity drop of the vehicle to be reduced, compared to that of a general AMT. Furthermore, various dynamometer-based experiments are carried out to prove the validity of the proposed shift control algorithm.
