对汽车制动能量再生系统的制动力分配控制方法进行了研究,提出了基于ABS系统的防止后轮先抱死控制的车辆制动力分配控制方法,建立了相应的再生制动系统前后轴制动力分配控制策略模型,对控制模型进行了仿真分析,并在本课题组建立的汽车能量再生制动试验台上进行了在环仿真试验,结果表明,该再生制动系统制动力分配控制策略能够保证汽车良好制动性能,制动过程中增加了电机制动率,从而提高了汽车制动能量的回收率。

A braking force distribution control method of auto regenerative braking system was investigated,and a braking force distribution control strategy of anti-rear-wheel-first-lock based on ABS was proposed.The relevant strategy model of front and rear wheel braking force distribution of regenerative system was set up,simulation of the model was carried out,and the method of control was validated on the test bench.The validated results indicate that the braking force distribution control strategy can assure good braking performance,and increase the motor brake rate during braking,to improve the reclaiming ratio of braking energy.
