电动汽车再生制动平顺性及能量回收仿真研究

针对电动机再生制动的加入影响电动汽车制动平顺性,采用并联制动方式,制定整车制动力分配策略和整车控制策略,建立恒定充电电流和电枢电流控制策略,利用软件建立复合制动仿真模型.结果表明:采用恒定电枢电流策略的汽车制动平顺性优于恒定充电电流策略,汽车能量回收效率较差.

Simulation Research on Regenerative Braking Comfort and Energy Recovery of Electric Vehicles

In view of the fact that the addition of electric motor regenerative braking affects electric vehicle braking comfort,Parallel braking method is adopted to reasonably distribute the braking torque of the front and rear axles,and establish a constant charging current and armature current control strategy.A simulation model was established using software platform.The results show that the braking comfort of the vehicle using the constant armature current strategy is better than the constant charging current strategy,and the vehicle energy recovery efficiency is poor.
