纯电动汽车电液制动系统再生制动控制策略分析研究

Analysis and Research on the Regenerative Braking Control Strategy of Pure Electric Vehicles Electric Liquid Brake System

制动能量回馈是电动汽车特有的功能之一,即电动汽车在制动时,驱动电机处于发电状态,可为电池充电,从而实现制动能量的再生利用。通过对电液制动系统再生制动控制进行研究,减少了运行中的动力浪费,延长了纯电动汽车的使用寿命。因此,应根据纯电动汽车现有的电液制动系统,设定有效的再生制动控制策略,从而完善纯电动汽车的构造,实现更高的舒适性。

The regenerative braking is one of the features of electric cars would have a special, namely electric vehicle during braking, driving motor is in the state of power, to charge the battery, so as to realize the braking energy regeneration and utilization. The research on regenerative braking control of electro hydraulic braking system is carried out, which reduces the power waste and prolongs the service life of electric vehicle. Therefore, we should set up the effective regenerative braking control strategy according to the existing electro liquid brake system of pure electric vehicle, so as to improve the structure of pure electric vehicle and achieve higher comfort.
