The invention discloses a driving motor torque limit control method and system, a new energy vehicle and a storage medium, and the method comprises the steps: S010, evaluating the torque limit of a dual clutch DCT transmission to a driving motor, and taking the torque limit as the first-stage limit MotTqMaxLimt1 of the driving motor to limit the torque; s020, the maximum torque limit value, evaluated by the driving motor system, of the driving motor is smaller than the first-stage limit MotTqMaxLimt1, and the maximum torque limit value serves as a second-stage limit MotTqMaxLimt2; s030, torque limitation of the power battery on the driving motor is evaluated, and the torque limitation serves as third-stage limitation MotTqMaxLimt3; and S040, the second-stage limit MotTqMaxLimt2 and the third-stage limit MotTqMaxLimt3 are smaller, and the smaller value serves as the final torque limit value MotTqMaxLimt of the driving motor. According to the invention, the maximum electric driving capability can be released.
