The invention provides a vehicle braking force distribution method and device, a controller and a storage medium, and the method comprises the steps that a braking signal of a vehicle braking pedal is obtained, and the total braking force of a vehicle is obtained; if it is judged that the current running speed of the vehicle is larger than the minimum vehicle speed for triggering braking energy recovery, the rear axle braking force of the vehicle is obtained through calculation; if it is detected that the front wheels of the vehicle tend to be locked, the front axle braking force of the vehicle is set to be the front axle critical locking demand braking force; if it is judged that the braking force of the rear axle is larger than the maximum regenerative braking force allowed by the rear axle, the mechanical braking force of the rear axle is set to be the difference value between the braking force of the rear axle and the maximum regenerative braking force allowed by the rear axle, and the regenerative braking force of the rear axle is set to be the maximum regenerative braking force allowed by the rear axle; and if it is detected that the rear wheels of the vehicle tend to be locked, the rear axle braking force of the vehicle is set to be the rear axle critical locking demand braking force. According to the invention, the maximum utilization of regenerative braking force is realized, and the optimal braking effect is realized through braking force distribution.

    本发明提供一种车辆制动力分配方法、装置、控制器及存储介质,方法包括:获取车辆制动踏板的制动信号,得到车辆的总制动力;若判定车辆当前的行驶速度大于触发制动能量回收的最小车速,则计算得到车辆的后轴制动力;若检测到车辆的前轮有抱死趋势,则设置车辆的前轴制动力为前轴临界抱死需求制动力;若判定后轴制动力大于后轴允许的最大再生制动力,则设置后轴的机械制动力为后轴制动力与后轴允许的最大再生制动力的差值,设置后轴的再生制动力为后轴允许的最大再生制动力;若检测到车辆的后轮有抱死趋势,则设置车辆的后轴制动力为后轴临界抱死需求制动力。本发明实现了再生制动力的最大化利用,通过制动力分配实现最佳的制动效果。
