电动汽车再生制动特点及控制策略

Regenerative Braking System Characteristics and Control Strategy of EV

再生制动对延长电动汽车续驶里程和延长机械制动器的使用寿命提供了很好的辅助制动功能。文章介绍了再生制动的影响因素和特点,并将各因素换算成当前最大允许制动力矩和当前最大允许制动功率后,基于ABS系统提出一种再生制动的较好控制策略,为开发设计具体的控制系统及算法奠定了良好的基础。

Based on the importance of regenerative braking system （RBS） to EV＇s sustained travel mileage and prolonging life of mechanical brake, this paper introduces the affecting factors and characteristics of RBS, at the same time the affecting factors are conversed into the present maximum allowed braking torque and power. At last, a better control strategy of RBS based on ABS is proposed, providing good base for developing specific control system and algorithm.
