Hybrid electric systems with reflux power have two forms during switching. First, the driving mode switching between the power source and the speed control mode switching between the continuously variable transmission (CVT) situation and the power reflux situation. Both of them will cause a sudden change in the output torque of the power coupling system affecting vehicle ride comfort during motion. To solve this problem,we propose a dynamic control strategy for plug-in hybrid electric vehicles (PHEVs) with reflux power by a coordinated control system involving the motor, engine, and clutch to minimize vehicle jerk. The results from MATLAB simulations indicate that the proposed control algorithm can be used to efficiently reduce torque fluctuations and jerk.
