四轮独立驱动电动汽车再生制动控制策略的研究

摘要: 针对四轮独立驱动电动汽车,设计了一种再生制动控制策略。充分考虑车速、电池的SOC(充电状态)、电池的最大充电电流和最大充电电压、电机的转矩特性、汽车制动Ⅰ曲线以及ECE法规曲线等因素的影响,该控制策略兼顾了制动稳定性和制动能量的回收效率。基于Simuliuk和AVLCruise软件平台进行了系统建模和联合仿真。仿真结果表明,该优化控制策略在保证制动安全、稳定的前提下,极大地提高了制动能量的回收效率。

Abstract: A regenerative braking control strategy was designed for an independent four wheel drive electric vehicle. Full consideration of factors of influence such as the vehicle's speed, state of charge of its battery, its maximum charge current and charge voltage and the torque characteristics of the electric motor, the braking curve and ECE regulation curve of the vehicle. The control strategy balances the braking stability and the recovery efficiency of braking energy. The modeling and collaborative simulation are performed with the software platforms of Simulink and AVL Cruise. The simulation results show that under the precondition of braking safety and stability, the control strategy greatly improves the recovery efficiency of braking energy.
