The invention discloses a regenerative braking system based on ESC hardware. The system comprises a brake pedal unit, a vacuum booster unit, a brake master cylinder unit, a hydraulic execution unit, four wheel cylinders, four wheel speed sensors, an ESC control unit, a vehicle control unit, a motor control unit and a battery control unit. The brake pedal feeling the same as that of a traditional hydraulic braking system can be guaranteed, no brake pedal travel simulator needs to be additionally mounted, when the ESC hardware fails, backup braking the same as that of the traditional hydraulic braking system can be provided, and the braking safety is guaranteed. Regenerative braking is finished through a drive motor, the hydraulic execution unit is used for finishing hydraulic braking, and a braking scheme which is low in cost and easy to implement and integrates regenerative braking and ESC is provided.
