The invention discloses a torque control method and device of a vehicle, a storage medium and an electronic device, and relates to the technical field of vehicles. The method comprises the steps that the motor rotating speed and the rotor angle of a motor in a vehicle are obtained; in response to the received active short-circuit instruction and the motor rotating speed being greater than a preset threshold value, determining a target current according to the rotor angle, the active short-circuit instruction being used for performing active short-circuit control on the motor, and the target current being used for representing a current of the motor in a rotating coordinate system; determining a target flux linkage value based on the target current and a target relation table; determining a target torque based on the target current and the target flux linkage value; and controlling the torque of the vehicle according to the target torque. The technical problems of high cost, difficult implementation, poor anti
