The invention discloses a braking force distribution method and device, equipment and a storage medium, and the method comprises the steps: obtaining an observation input parameter and an actual yaw velocity, and carrying out the preprocessing of the observation input parameter, and obtaining a preprocessing parameter; and calculating an ideal yaw velocity according to the preprocessing parameters. Then, feedback control is constructed according to the observation input parameters, the actual yaw velocity and the ideal yaw velocity, and feed-forward control is constructed according to the observation input parameters; when the vehicle speed is not larger than the first preset vehicle speed, the expected yaw moment is calculated through feedforward control; when the vehicle speed is not less than a second preset vehicle speed, calculating an expected yaw moment by using feedback control; when the vehicle speed is larger than the first preset vehicle speed and smaller than the second preset vehicle speed, the expected yaw moment is calculated through compound control, and the second preset vehicle speed is larger than the first preset vehicle speed. And finally, according to the expected yawing moment, braking force distribution is performed to obtain expected braking force. The steering and braking cooperation capability of the drive-by-wire chassis can be improved.
