The invention discloses a vehicle braking force distribution method and device, electronic equipment and a storage medium. The method comprises the steps that the target braking deceleration of a vehicle is obtained in real time, and the total target braking torque of the vehicle is obtained based on the target braking deceleration; obtaining a torque distribution proportion between a front axle and a rear axle based on the obtained vehicle; a front axle target braking torque and a rear axle target braking torque are obtained based on the total target braking torque according to the torque distribution proportion; a front axle maximum recovery torque allowed by a front axle is obtained, and a front axle recovery torque strategy is obtained based on the front axle maximum recovery torque and the front axle target braking torque; a rear axle maximum recovery torque allowed by a rear axle is obtained, and a rear axle recovery torque strategy is obtained based on the maximum recovery torque and the rear axle target braking torque; and the front axle torque recovery strategy and the rear axle torque recovery strategy are executed to complete braking force distribution of the vehicle. In this way, the recovery torque of the motor can be fully utilized, the electric braking utilization rate is increased, and the vehicle endurance is prolonged.

    本申请公开了一种车辆制动力分配方法及装置、电子设备、存储介质,该方法包括:实时获取车辆的目标制动减速度,并基于目标制动减速度得到车辆的总目标制动扭矩;基于获取车辆得到前轴与后轴之间的扭矩分配比例;按照扭矩分配比例基于总目标制动扭矩得到前轴目标制动扭矩和后轴目标制动扭矩;获取前轴所允许的前轴最大回收扭矩,基于前轴最大回收扭矩和前轴目标制动扭矩得到前轴回收扭矩策略;获取后轴所允许的后轴最大回收扭矩,基于最大回收扭矩和后轴目标制动扭矩得到后轴回收扭矩策略;执行前轴回收扭矩策略和后轴回收扭矩策略,以完成车辆的制动力分配。这样,本申请能够充分利用电机的回收扭矩,提升电制动利用率,增加车辆续航。
