The invention relates to the technical field of automobile braking, and discloses a braking control method, system and equipment for a distributed driving electric vehicle and a medium. The method comprises the steps that for the distributed driving electric vehicle, state data of the vehicle during braking are obtained, and whether the braking intention of a driver during braking is conventional braking or emergency braking is recognized according to the state data; the current longitudinal speed and the current side slip angle of the vehicle are obtained; the braking intention of a driver, the current longitudinal speed of the vehicle and the difference between the current side slip angle of the vehicle and the expected side slip angle of the vehicle in the absolute stable state serve as input data, the input data are input into the trained braking control model, and the braking torque used for stably braking the vehicle is obtained; and the vehicle is stably braked according to the braking intention of the driver and the obtained braking torque. According to the braking control method of the distributed driving electric vehicle, the control effect of the braking stability of the vehicle can be improved.
