摘要
能量回收率作为评价制动系统常用的指标,其缺点是对制动系统优化设计的指导较弱。通过分析多款混合动力汽车试验数据,对车辆制动系统在常规制动情况下的能量回收能力进行研究,得到车辆最大回收转矩和车速的关系。基于车辆的回收转矩限制,论文提出了电制动系数的概念。然后从理论上深入分析了电制动系数和能量回收率的关系。其次,提出了基于电制动系数评价单次工况和循环工况车辆能量回收能力的方法。最后利用试验数据验证了电制动系数评价方法的有效性。研究表明:电制动系数的分布可以表征制动系统的能量回收能力;单次工况,电制动系数高于0.8区域的面积占整个区域面积的比例可以作为评价车辆能量回收能力的指标;循环工况,车辆工作点在电制动系数高于0.8区域的比例可以作为评价车辆能量回收能力的指标。
The energy recovery rate is used as an index to evaluate the braking system,and its shortcoming is that the assistance for the optimal design of the braking system is weak.By analyzing the test data of a variety of hybrid electric vehicle,the energy- savingpotential of the vehicle braking system under the normal braking condition is studied,and the relationship between maximum braking torque and vehicle velocity is obtained.In this paper,the concept of electric braking coefficient is presented.Then,the relationship between the electric braking coefficient and the energy recovery rate is analyzed theoretically.Secondly,a method based on the electric braking coefficient is proposed to evaluate the energy recovery ability of vehicles under the condition of single operation and driving cycles.Finally,the validity of the method is verified by the test data.The research results are as follows.The distribution of electric braking coefficient can be used to characterize the energy recovery of the braking system.In a single operating condition,the proportion of the area that the electric braking coefficient is higher than 0.8 can be used as an index to evaluate the braking system.In a driving cycle condition,the proportion of the vehicle operating point whose electric braking coefficient higher than 0.8 can be used as an index to evaluate the vehicle energy recovery capability.
