摘要:

為了有效提高ISG重度混合動(dòng)力汽車(chē)(full hybrid electric vehicle assisted by an integrated starter generator,ISG-FHEV)發(fā)動(dòng)機和電機驅動(dòng)系統效率以及整車(chē)的燃油經(jīng)濟性,設計了一種等效燃油消耗最小控制策略(equivalent consumption minimization strategy,ECMS);在分析ISG-FHEV功率分流模式的基礎上,同時(shí)考慮發(fā)動(dòng)機和電機驅動(dòng)系統效率,構建出包含發(fā)動(dòng)機和電機驅動(dòng)系統的功率分配、ISG電機和主電機間的功率分配兩個(gè)控制變量的整車(chē)等效燃油消耗最小目標函數;引入龐特里亞金極小值原理(pontryagin’s minimum principle,PMP)并加入電池SOC偏差控制確定等效因子;最后,進(jìn)行了仿真和對比分析;結果表明,與基于規則的控制策略相比,發(fā)動(dòng)機效率提高9%,ISG電機和主電機總效率提高11.4%,百公里耗油量降低9.98%。

Abstract:

In order to effectively improve the drive efficiency of the engine and motor and the whole vehicle fuel economy for Full hybrid electric vehicle assisted by an Integrated Starter Generator (ISG-FHEV),this paper designed an equivalent consumption minimization strategy (ECMS). Considering the engine and the motor drive system efficiency based on the analysis of ISG-FHEV power split mode,the equivalent fuel consumption minimization objective function containing two control variables which are power distribution between the engine and motor drive system and the ISG motor and the main motor was constructed. By introducing Pontryagin’s Minimum Principle (PMP) and the deviation control of battery state of charge (SOC) to determine the equivalent factor. Finally,we carried on the simulation and comparative analysis. The simulation results show that engine efficiency increases 9%,total motor efficiency is up 11.4%,fuel consumption to travel 100 km decreases 9.98% compared with the Rule-based control strategy.
