Abstract：Drivability of automotive drivetrain is one of the main properties of the vehicles, and is closely related to the dynamic performance and comfort of passenger feelings. The change of engine torque and the release and engagement of clutch influence the drivability of automotive drivetrain greatly. This paper introduces the dynamic model of each part of the drivetrain, and demonstrates the working scenarios that affect drivetrain drivability: launch control, gear shift control, anti-jerk control, engine start-stop control and backlash compensation control. For each working scenario, the control method and algorithm are described in detail. Finally, the conclusions are given and the research hotspots in the near future are pointed out, including coordination control of electrified vehicles as well as the effects of intelligent control.
