摘要
回馈制动能有效提高分布式电驱动车辆的能量效率。论文分析了分布式电驱动车辆回馈制动系统的结构、电机的性能及制动法规的约束条件,提出了基于非线性规划方法的最大能量回馈制动控制策略,并结合回馈制动系统的特性分析了制动力分配的特点。通过仿真分析了典型制动过程及典型工况循环的制动能量回收效果,结果表明,与理想制动力分配策略相比,本文提出的回馈制动控制策略能获得更高的能量回收效率。
Regenerative braking control can improve the energy efficiency of distribute drive electric vehicle. The structure of the regenerative braking system,the characteristics of the motor and the constraint conditions of braking regulations are analyzed. A regenerative braking control strategy aiming at acquiring the maximum regenerative energy is proposed based on nonlinear programming. The characteristics of the regenerative braking control strategy are analyzed with consideration of the characteristics of the regenerative braking system. The regenerative energy efficiencies of typical braking conditions and driving cycle are analyzed through simulation. Results show that the proposed strategy can achieve better regenerative energy efficiency than ideal braking force allocation.
