The invention discloses a method and device for reducing automobile braking noise. The method comprises the steps that the automobile braking noise and automobile information are collected; determining the current working condition of the automobile; obtaining an automobile brake noise prediction model of the automobile under the current working condition; wherein the automobile brake noise prediction model is a corresponding relation model of automobile information and brake noise of an automobile; the brake noise and the vehicle information are matched with an automobile brake noise prediction model, and when the brake noise and the vehicle information are matched with the automobile brake noise prediction model, a brake noise calibration value is determined according to the brake noise prediction model; when the braking noise reaches the braking noise calibration value, the braking torque is distributed again, so that the braking noise is lower than the braking noise threshold value; wherein the braking torque comprises a braking torque provided by wheel energy recovery and a hydraulic braking torque. The noise generated when the automobile is braked can be reduced, the NVH performance of braking is met, and the driving comfort of a driver is greatly improved.
