The invention discloses a vehicle braking force distribution method and device, a vehicle and a storage medium, and the method comprises the steps that the required braking torque value and the rear wheel braking torque limiting value of a target vehicle at the current moment are determined, and if the required braking torque value is larger than the rear wheel braking torque limiting value, the target vehicle is started; if yes, the rear wheel braking torque value of the target vehicle is configured to be the target electric braking torque value, and the target electric braking torque value is the rear wheel braking torque limiting value; configuring a front wheel brake hydraulic pressure value of the target vehicle according to the required brake torque value and the rear wheel brake torque limit value; and distributing braking force to the target vehicle according to the target electric braking torque value and the front wheel braking hydraulic pressure value. By means of the method, when the rear wheel braking torque limit value is reached, the rear wheel braking torque value is controlled not to exceed the rear wheel braking torque limit value, braking is achieved through the front wheel hydraulic value, on the basis, the electric braking utilization rate can be increased, and the rear wheel locking probability can be reduced as much as possible.

    本申请公开了一种车辆制动力分配方法、装置、车辆及存储介质,该方法包括:确定当前时刻目标车辆的需求制动扭矩值以及后轮制动扭矩限制值,若需求制动扭矩值大于后轮制动扭矩限制值,则将目标车辆的后轮制动扭矩值配置为目标电制动扭矩值,目标电制动扭矩值为所述后轮制动扭矩限制值;根据需求制动扭矩值以及后轮制动扭矩限制值,配置目标车辆的前轮制动液压值;根据目标电制动扭矩值以及前轮制动液压值为目标车辆分配制动力。通过该方法,在达到后轮制动扭矩限制值时,控制后轮制动扭矩值不超过后轮制动扭矩限制值,同时通过前轮液压值实现制动,基于此,可以提高电制动利用率,可以尽可能减少后轮抱死的概率。
