The invention discloses a braking force distribution method, device and equipment, a medium and a vehicle, and relates to the technical field of vehicles. The braking force distribution method comprises the steps of obtaining target data; predicting a longitudinal acceleration and a lateral acceleration of the vehicle based on the target data; the target braking force currently needed by the vehicle is calculated through the longitudinal acceleration and the transverse acceleration; according to the friction braking capacity of each wheel, the current actual friction braking force of each wheel and the current actual recovery braking capacity of a front axle and a rear axle of the vehicle, the maximum recovery capacity capable of being provided by an actuator, a front axle motor and a rear axle motor corresponding to each wheel is calculated; and performing braking force distribution on each wheel, a vehicle front axle and a vehicle rear axle based on the target braking force and the maximum recovery capacity which can be provided by the actuator corresponding to each wheel, the front axle motor and the rear axle motor. Through the scheme disclosed by the invention, the NVH interference can be avoided while the requirement of vehicle stability can be met.
