A Dynamic Coordinated Control Method for Parallel Hybrid Electric Vehicle Based on Model-matching-control

Based on the analysis on the difference of dynamic response characteristics between engine and electric motor,a dynamic coordinated controller is designed using model-matching-control method.Then a forward-facing simulation model for parallel hybrid electric vehicle(PHEV) is set up and a simulation on PHEV with both dynamic coordinated control and proportional control is conducted.The results show that compared with proportional control, the dynamical coordinated control has higher torque control accuracy and better dynamic characteristics,so can effectively control the coupling between motor and engine.Finally,the control method is validated by a hardware-in-the-loop simulation test.
