The invention provides a regenerative braking system, an electric vehicle and a regenerative braking system control method and device, and relates to the technical field of electric vehicle braking. The regenerative braking system is used for braking of the electric vehicle and comprises a brake pedal, a load sensor, a controller, a first brake, a second brake and a braking force sensor, and the load sensor is used for detecting acting force acting on the brake pedal; the controller is used for obtaining the corresponding initial braking force F0 according to the value of the acting force detected by the load sensor and controlling the first brake to be started according to the initial braking force F0; when the absolute value of the difference value between the value of the first braking force detected by the braking force sensor and the initial braking force is larger than the set threshold value, the second brake is controlled to be started, and a second braking force acting on the driving device is generated. In this way, in the braking process, the electric vehicle has a constant deceleration level, so that gentle deceleration of the electric vehicle is achieved, and the braking feeling of a driver is improved.
