Improper management of engine starting in-motion of PHEV (plug-in hybrid electric vehicle) may result in noticeable jerk. The engine ignition time and the clutch state are the key to the ride comfort control. Therefore, a clutch pressure fuzzy control algorithm for PHEV mode transition is proposed, which bases on torque coordination control and starting engine at target speed. And the strategy is verified through bench test and road test, and the test results indicate that the torque coordination control strategy which is based on engine starting at target speed and clutch pressure fuzzy control algorithm can improve vehicle ride comfort.
