混合动力汽车能量控制策略研究现状

Research status of energy control strategy for hybrid electric vehicle

随着环境污染问题的日益凸显和石油资源的逐渐匮乏,混合动力汽车研究的意义和价值也得到了广泛认可。混合动力汽车由两种或两种以上的能源提供动力,具有纯电动汽车高效率低排放的优点,又能够显著增加电动汽车的行驶里程,具有传统燃料车高比能量、高比功率的长处,又可获得传统车无法达到的优化控制目标。如何对多能量源与其他部件协调配合,进行优化组合,以减少燃油消耗、降低排放,是混合动力汽车研究中面临的一个关键问题。文章重点阐述了混合动力汽车能量控制策略的三种分类方式,并对几种常见能量控制策略进行介绍和比较,得出这些算法的优缺点及适用场合。

With the rising severe environmental pollution problems and gradual scarcity of oil resources, the significance and value of research for hybrid electric vehicle are widely recognized. Hybrid electric vehicle is powered by two or more energy sources. It has the advantage of high efficiency and low emissions as pure electric vehicle, but a higher running range than it. It also has the advantage of higher energy density and power density as traditional fuel vehicle, while it can get the optimal control target which the traditional vehicle can not achieve. The key problem on hybrid electric vehicle research is how to coordinate the multi-energy sources system with other components and optimize the combination to reduce fuel consumption and emissions. This paper mainly explains three classification methods of the energy control strategy of hybrid electric vehicles, and introduces and compares some kinds of common energy control strategies, of which the advantages and disadvantages as well as applicable situations are then obtained.
