Abstract

In this paper, firstly the braking force distribution is analyzed in theory, and the scope within regulations of braking force distribution is calculated. Secondly, a braking energy recovery maximally control strategy is proposed, which assigns the maximum braking force to motor within the ECE regulation, and the other three control strategies that braking force is distributed as Belt line, I line and having no limit is given to comparative analysis. And then, according to the parameters of vehicle and braking system, the FWD and RWD vehicle model and the control strategies mentioned above are built by the cosimulation based on MATLAB/Simulink and CRUISE to analyze the braking energy recovery rate in each braking process of different braking intensities, and the energy-saving rate in five types of running cycle. At last, by the comparative analysis of simulation, it can be acquired that the effect of braking energy recovery in FWD is better than RWD, and the braking energy recovery maximally control strategy proposed is effective which is the nearest to the maximum potential of braking energy recovery.

考虑前轴和后轴驱动的制动力分配策略对能量回收效果的影响分析

本文首先从理论上对制动力分配进行了分析，并计算了制动力分配的规定范围。其次，提出了在ECE规定范围内为电机分配最大制动力的制动能量回收最大化控制策略，并将制动力分配为带线、I线和无限制三种控制策略进行对比分析。然后，根据车辆和制动系统参数，通过MATLAB/Simulink和CRUISE联合仿真，建立了FWD和RWD车辆模型及上述控制策略，分析了不同制动强度下各制动过程的制动能量回收率，以及五种工况下的节能率。最后，通过仿真对比分析可知，在FWD工况下制动能量回收效果优于RWD工况，所提出的制动能量回收最大化控制策略是最接近制动能量回收最大潜力的有效控制策略。
