Abstract
In this study, a modified shift control algorithm for improving the shift quality of a parallel hybrid drivetrain with an automated manual transmission (AMT) is proposed. Improving shift quality of general AMT demands the sophisticated control for the engagement of clutch, which is generally known to be difficult. But in the parallel hybrid vehicle, both engine and motor can control the speeds of each clutch plate. Therefore it provides the easier clutch control in shift than general AMT. Consequently, it also permits the much reduced shift shock during the shift period. Furthermore various dynamometer-based experiments are carried out to prove the validity of the proposed shift control algorithm.
