N2 - According to the PEV's structure, the dynamic model considering the driving shaft's torsional vibration in the drivetrain is build up and the approximate mathematical model of the transmitted torque in AMT that can be used in shifting progress control is deduced. This model is validated in trial that it can control the torque transmitted in AMT and weaken the oscillation of the output shaft's rotate speed after shifting into neutral gear. The real vehicle test results shows that the proposed control strategy based on torsional vibration model can decrease the time of power interrupt, reduce the oscillation of vehicle speed and improve the shifting quality.
