摘要
通过对并联混合动力电动汽车(PHEV)的仿真和对发动机工作点在发动机效率map图中分布情况的 分析,研究了影响PHEV的发动机在高效区工作的因素。研究表明:驱动系统能量管理和控制策略对PHEV的发 动机在高效区工作的影响最为显著,其次是换挡策略、循环工况以及发动机高效区的位置和分布的影响。
Through the simulation of parallel hybrid electric vehicle and the analysis on efficiency map of its engine, the factors making engine works within efficient operation region are studied. This result shows that the most significant affecting factor is the powertrain energy control strategy. And the other factors next to it are shifting strategy, driving cycle and the location and distribution of efficient operation region of the engine. These conclusions provide a basis for the design and control of parallel HEV, aiming at the objective of lowering fuel consumption.
