摘要
为了提高轮毂电机电动汽车再生制动的占比与制动能量回收,提出了一种新的复合制动系统制动力分配策略.首先,针对轮毂电机再生制动和线控摩擦制动的特点,结合车辆参数及 ECE 法规对制动性能的要求,提出不同条件下的前后轴制动力分配策略.其次,根据不同制动工况提出集成制动装置内部再生制动和摩擦制动之间的制动力分配策略.最后,在Matlab/Simulink软件中模拟不同工况、不同强度下的制动过程.结果表明:所提策略可以充分利用再生制动的优势,为摩擦制动分担部分制动需求,且在小强度制动时再生制动占比较高.
Abstract
In order to improve the share of regenerative braking and braking energy recovery in hub-motor e-lectric vehicles,a new braking force distribution strategy for composite braking system is proposed.First,the front and rear axle braking power distribution strategies under different conditions are proposed for the character-istics of hub motor regenerative braking and line-controlled friction braking,combined with the vehicle parame-ters and the braking performance requirements of the ECE regulations.Secondly,the braking force distribution strategy between regenerative braking and friction braking within the integrated braking device is proposed ac-cording to different braking conditions.Finally,the braking process under different working conditions and dif-ferent strengths is simulated in Matlab/Simulink software.The results show that the proposed strategy can fully utilize the advantages of regenerative braking,share part of the braking demand for friction braking,and the re-generative braking accounts for a higher percentage of the braking force in small intensity braking.
