摘要
对电动汽车电液复合制动系统的结构和工作原理进行了简单的概述。在分析基于传统摩擦制动系统的再生制动控制策略的基础上,重点讨论了电液制动系统对电动汽车制动能量回收能力的影响。结合电液复合制动系统能够对电动汽车制动过程进行精确控制的特点进行的理论分析表明,将摩擦制动力矩尽量分配到汽车非驱动轴能够使制动能量回收最大化。根据上述结论设计了基于电液复合制动系统的再生制动控制策略,在ADVISOR2002中进行了仿真研究,验证了该再生制动控制策略的有效性。结果表明,该再生制动控制策略相较于传统的并行制动分配控制策略,能够提高电动汽车的制动能量回收率和整车有效能量回收率。
The structure and working principle of electro-hydraulic hybrid brake system of electric vehicle is introduced briefly. Based on analysis of the regenerative braking control strategy based on conventional friction brake system, the influence of electro-hydraulic brake system on ability of braking energy recovery of electric vehicle is discussed. Combining with the characteristics that electro-hydraulic hybrid brake system can control the braking process of electric vehicle precisely, a theoretical analysis is conducted, which shows that distributing friction braking moment to non-drive axle as much as possible can maximize braking energy recovery. On this basis, the regenerative braking control strategy based on electro-hydraulic hybrid brake system is designed, the model of the braking control strategy is set up in ADVISOR2002 and the simulation is carried out to verify the effectiveness of the control strategy. The result shows that this regenerative braking control strategy can improve braking energy recovery rate and effective energy recovery in electric vehicle compared with traditional parallel brake distribution control strategy.
