摘要
为提高四驱电动汽车制动能量回收量和避免制动过程中车轮抱死,根据车辆动力学理论和ECE法规得到车辆再生制动系统安全再生制动区域并分析其限制作用,结合双电机特性设计了再生制动系统控制策略。MATLAB/Simulink仿真结果表明,该控制策略相较于并联控制策略可将回收能量提高10%,并基于d SPACE验证了其有效性和实时性。
In order to improve the recovery of braking energy and avoid the wheels lock in the process of braking of All-Wheel Drive(AWD) Battery Electric Vehicle(BEV), the safety regenerative braking area of vehicle regenerative braking system is obtained and its restrictive effect is analyzed according to the vehicle dynamics theory and ECE regulations. The control strategy of regenerative braking system is designed based on the characteristics of dual motors. The simulation results of MATLAB/Simulink show that this control strategy can improve the energy recovery by 10% compared with the parallel control strategy, and its effectiveness and real-time performance are verified based on dSPACE.
