The invention discloses a control system for automobile brake energy recovery. The control system is characterized in that the pedal force is amplified by a vacuum booster after a brake pedal is pedaled, and a brake master cylinder and a brake wheel cylinder begin to work to output a hydraulic brake force; moreover, pressure sensors of the brake master cylinder and the brake wheel cylinder are used for transmitting the current pressure to a brake energy recovery controller, the brake energy recover controller is used for controlling the electric brake force of an automobile according to the current hydraulic brake force, the reduction value of the hydraulic brake force is equal to the increase value of the electric brake force, and the total braking force remains unchanged. Due to the adoption of the structure, the control system realizes the control and redeployment of the hydraulic brake force and the electric brake force of the automobile, so that the hydraulic brake force and the electric brake force of the automobile are matched with each other to achieve an optimum efficiency, and the comfort of the vehicle is met while the automobile energy recovery is met; moreover, sufficient brake force of the vehicle is guaranteed, and the safety of the automobile is guaranteed.
