摘要/Abstract

摘要： 本文中基于混合动力系统内部能量流,提出系统平均综合传动效率概念,并建立基于能量计算的混合动力系统理论油耗模型。结合混合动力系统基本节油途径,考虑再生制动、发动机平均燃油消耗率和平均综合传动效率变化因素,建立混合动力系统理论综合油耗增量计算模型,并针对功率分流式混联混合动力系统的油耗及其影响因素进行深入的定量分析。整车燃油经济性仿真结果和油耗影响因素理论分析结论验证了所提出方法的合理性。

Abstract: Based on the hybrid power system internal energy flow , the concept of average integrated transmission efficiency is proposed and the theoretical fuel consumption model is built on the basis of energy calculation in this paper. Combined with the basic fuel-saving approach of hybrid power system, the incremental theoretical calculation model of fuel consumption is established, considering the factors of regenerative braking, average engine fuel consumption and average integrated transmission efficiency change. Finally, the quantitative analysis of fuel consumption and the influencing factors of a typical power-split hybrid power system is carried out. Simulation results of vehicle fuel economy and the theoretical analysis of the fuel consumption influencing factors show the rationality of the proposed method

Key words: hybrid electric bus, theoretical fuel consumption model, average integrated transmission efficiency, power-split hybrid system, fuel saving analysis
