Dual clutch transmissions (DCTs) are recognized as being suitable for electric drive applications as they can drive with high efficiency and achieve good shifting comfort.A two-speed DCT electric drivetrain is described in this paper, comprised of only two gear pairs and a final drive gear here in the two-speed gearbox.The fundamental shifting control algorithm is provided.On the testing rig of University of Technology, Sydney (UTS) powertrain lab, shifting controls and some driving cycle controls were realized.The results demonstrated that the control algorithm functioned well both in transient shifting control process and in harry potter magsafe case the driving cycle conditions.
