摘要
和传统汽车的仿真研究一样,建立正确的模型是混合动力汽车仿真研究的前提。和传统汽车相比,在控制上混合动力汽车多了更复杂的整车控制策略这一关键技术,因此所建立的模型更强调检验其在不同整车控制策略时的动态适应能力。基于先进实时系统分析工具PSAT,提出了一套混合动力汽车模型科学仿真研究过程。对某混合动力系统进行的仿真实践表明,所制定的方案科学合理,修正优化后的整车模型能准确贯彻执行混合动力汽车的控制策略指令,为后面基于不同优化目标的详细整车控制策略的开发打下了基础。
Like conventional vehicle, proper model establishment is the premise of research on hybrid vehicle. Compared with conventional vehicle, hybrid vehicle adopts a key and more complicated technology in control that is complete vehicle control strategy. Hence, the established model pays more attention to the dynamic adaptability under different complete vehicle control strategy. A series of scientific artificial research processes of hybrid vehicle model are advanced based on PSAT——an advanced real -time system analytical tool. The artificial practice of a certain hybrid power system shows that the plan is scientific and reasoning, the corrected and optimized complete vehicle model can properly implement the control strategy instruction of hybrid vehicle, which provides foundation for further development of complete vehicle control strategy aiming at different optimization objectives.
