摘要
以混合动力电动汽车为研究对象,以驾驶员的制动意图和制动能量回收率为设计指标,基于最优控制理论设计了一套有效的制动力分配模型。仿真结果表明,该控制方法能够显著提高汽车制动时的响应速度,大约在0.5 s以内就能实现制动意图,并且能够提高制动能量回收率10%左右。
Taking the driver＇s braking intention and the rate of braking energy regeneration as design targets, an effective braking force distribution model for a hybrid electric vehicle is set up based on optimal control theory, and a simulation is conducted. The result of simulation shows that the control scheme can significantly speed up the dynamic response to braking. The driver＇s braking intention can be achieved within 0.5s and the rate of energy regeneration can increase by about 10%.
