摘　　要：在PRIUS工作模式和试验研究的基础上,设计了逻辑门限值控制策略,并结合整车仿真模型研究基于逻辑门限控制策略的控制效果.在UDDS工况下对整车的速度特性、动力性、蓄电池SOC和油耗进行了仿真分析.仿真结果表明,基于逻辑门限的控制策略能够实现各种工作模式间的合理切换,整车的动力性能、燃油经济性和实车数据基本吻合,验证了整车仿真模型和控制策略的有效性.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.
