The invention discloses an adaptive control system and an adaptive control method of electric vehicle brake feedback energy. The control system comprises a vehicle weight sensor, a vehicle controller, a brake sensor, a power battery pack, a battery management system, a motor controller and a driving motor, wherein the vehicle weight sensor is provided with a contact; a lead of the contact is connected with an input end of the vehicle controller; an output wire of the brake sensor is connected with the other input end of the vehicle controller; the vehicle controller is simultaneously connected with the battery management system and the motor controller; the battery management system is connected with the power battery pack and is used for controlling the power battery pack to supply power; the high-voltage direct-current output of the power battery pack is connected with the high-voltage direct-current input of the motor controller; the high-voltage alternating-current output of the motor controller is connected with an input cable of the driving motor. The driving motor is controlled according to a signal transmitted by the brake sensor to be converted into a power generator, energy feedback is realized, and adaptive control is realized according to no load or heavy load of a vehicle.
