The invention discloses a regenerative braking force distribution method for a new energy automobile, and belongs to the technical field of new energy automobiles. The method comprises the steps of S1, distributing the total braking force to a front wheel and a rear wheel, and distributing the braking force to the rear wheel as much as possible on the premise that safety and braking stability areboth considered; and S2, dividing the distributed rear wheel total braking force into rear wheel friction braking force and motor braking force, distributing the rear wheel total braking force to themotor as much as possible under the condition that the motor can meet the braking requirement, and compensating by the rear wheel friction braking force when the motor braking does not meet the requirement. The braking capacity of the motor can be brought into full play, and efficient braking energy recovery is achieved.

    本发明公开了一种新能源汽车再生制动力分配方法,属于新能源汽车技术领域。该方法包括:S1、将总制动力分配给前轮和后轮,在兼顾安全及制动稳定性的前提下,将制动力尽可能多地分配给后轮;S2、将分配得到的后轮总制动力分为后轮摩擦制动力和电机制动力,在电机能够满足制动需求的情况下,将后轮总制动力尽可能多地分配给电机,当电机制动不满足需求时,由后轮摩擦制动力进行补偿。本发明能够充分发挥电机制动能力,实现高效制动能量回收。
