摘要
以大运新奥普利轻型卡车为目标车型,在保证动力性的前提下,设计了一款单轴并联式混合动力城郊物流车。基于Matlab/Simulink软件搭建了整车模型,制定了逻辑门控制策略进行转矩分配,为提高燃油经济性,制定了模糊逻辑控制策略,基于NEDC工况通过仿真与台架试验验证了模型与策略的可信性。基于CHTC-LT工况进行了仿真分析。结果表明:该模糊逻辑控制策略在满足动力性的前提下,与逻辑门控制策略相比,电池SOC的变化更为平缓,百公里燃油消耗量下降,燃油经济性提高。
Having brought great convenience to mankind,the automobiles have also caused many problems such as energy crisis,environment pollution and enormous greenhouse gas emission.Therefore,China,by putting forward goals with carbon neutrality and carbon peaking,has attached great importance to automobile industry with bound-duties.Following the calls for energy conservation and emission reduction all over the world,more and more researchers start to put emphasis on hybrid electric vehicles in various countries.Hybrid electrical vehicles,with the advantages of low emission and fuel consumption during long drives,have brought great significance on energy conservation and environmental protection.In addition,different driving cycles applied in vehicle development cause various impacts on economy and emissions.For a long time,Chinese car companies have been using foreign driving cycles for development,and there is still room for improvement.The paper,taking Dayun New Opley light truck as the target model,illustrates a design of hybrid-powered suburban logistics vehicle under the premise of ensuring power.According to the selection and matching of power components and hybrid types,a vehicle simulation model was built based on the Matlab/Simulink platform,with which a rule-based logic gate control strategy and a fuzzy logic control strategy were designed.Simulations were performed under part of the New European Driving Cycle(NEDC)and China Heavy-duty Commercial Vehicle Test Cycle-Light Truck(CHTC-LT).A single-shaft parallel hybrid test bench with the same configuration as the research object was built in the paper,and some NEDC hybrid conditions were selected for tests.The research confirms that two control strategies,the one with fuel consumption obtained by simulation consistent with the change and the one obtained from the bench test,were credible.Finally,an analysis was carried out based on the CHTC-LT operating conditions.The result shows that once fuzzy logic control strategy meets the criteria of dynamic properties,the SOC of the battery changes more stably with lower fuel consumption per kilometer.
