摘要
针对具有双轴双电机四驱结构的电动汽车,设计了一种基于I线制动力分配策略。该策略在制动时,前后轴制动力按照I线分配,前后电机同时回收能量,既发挥了制动能量回收潜力,又保证了制动稳定性。仿真结果表明,该策略能回收更多的能量,制动力分配曲线与I线相吻合,保证了制动稳定性,也验证了该策略的有效性。
An ideal braking force distribution strategy based on curve I is designed for a two-axle two motor 4WD electric vehicle. With the strategy, the braking forces of front and rear axles are distributed as per I-curve during braking, and both front and rear motors recover braking energy, taking its potential of braking energy recovery while assuring braking stability. The results of simulation show that the strategy can recover more energy with a braking force distribution pattern well agreeing with I.curve, tiveness.
