摘要:基于某紧凑运动型多用途车辆开发双电机串并联混动系统,设计双电机混动控制策略,提出用于不同运行工况的纯电驱动、串联驱动、并联驱动3种稳态混动模式;通过发动机起动和停机、离合器关闭和打开4种过渡工况实现不同混动模式之间的切换。基于Matlab/Simulink搭建双电机混动系统车辆仿真模型,分析双电机串并联混动系统的经济性和动力性。结果表明:双电机串并联混动模式全球统一轻型车辆测试循环油耗为6 L/(100 km),车速0~100 km/h的加速时间为9.1 s,双电机串并联混动节油显著,动力性良好。

Abstract:Based on a compact SUV vehicle, double motors serial and parallel hybrid system is developed, and a hybrid control strategy is built. The three steady hybrid modes: electric drive, serial drive, and parallel drive are developed for different operating conditions.Hybrid modes are switched through four transitional modes: engine starting, engine stopping, clutch closing and clutch opening.The vehicle simulation model of the double motors hybrid system is built based on Matlab/Simulink to analyze the fuel economy and driving performance of the double motors serial and parallel hybrid system.The results show that the fuel consumption of the WLTC is 6 L/(100 km), and the acceleration time from 0 to 100 km/h is 9.1 s. The double motors serial and parallel hybrid system has good fuel economy and driving performance.
Keywords:series and parallel; hybrid; control strategy; hybrid mode
