The invention relates to a braking energy control method and device, computer equipment and a storage medium. The method comprises the following steps: acquiring a total braking force expected value; a braking energy recovery function is activated, and a front axle recovery torque threshold value, a rear axle recovery torque threshold value, a front axle recovery torque expected value and a rear axle recovery torque expected value are obtained; selecting a front and rear axle distribution rule according to the current vehicle condition driving stage, the front axle recovery torque threshold value and the rear axle recovery torque threshold value; a front axle recovery torque target value, a rear axle recovery torque target value, and a hydraulic brake target value of a master cylinder are calculated using a total braking force expected value, a front axle recovery torque expected value, and a rear axle recovery torque expected value on the basis of front and rear axle distribution rules. By adopting the method, the energy recovery rate of the vehicle can be improved and the endurance mileage can be increased on the basis of ensuring the stability and the safety of the vehicle for the split-axle four-wheel-drive vehicle.
