石油资源匮乏与环境污染已经成为制约汽车工业可持续发展的两大难题。混合动力汽车采用内燃机和电动机作为动力源,成为国际公认的解决两大难题的有效策略。在总结混合动力大客车发展现状的基础上,分析串联式、并联式、混联式及复合联接式混合动力汽车驱动方案,并提出发展混合动力大客车需解决的关键技术。 Lack of oil resources and environmental pollution have become the two major problems restricting the sustainable development of the automotive industry. The use of internal combustion engines and electric motors as power sources in hybrid vehicles has become an internationally accepted effective strategy to solve two major problems. Based on the summary of the development status of hybrid buses, the driving schemes of series, parallel, hybrid and compound hybrid vehicles are analyzed and the key technologies needed to be solved for the development of hybrid buses are proposed.
