Research on Parallel-series Hybrid Electric Vehicle's Modeling and Control Strategy

On the basis of PRIUS working modes and experiment research,a logic threshold control strategy was designed. Combined with the simulation model of the vehicle,the control performance of the proposed control strategy was studied. The speed characteristic,power performance,battery SOC(state of charge) and fuel consumption of the vehicle have been studied under the UDDS driving cycle. The simulation results show that the control strategy based on logic threshold can realize rational switch in different operation modes,the vehicle power performance and fuel economy can match with the vehicle experiment data,and this verifies the feasibility of the whole-vehicle simulation model and the control strategy.
