The invention relates to the technical field of vehicles, and discloses a motor driving current abnormity determination method and device, equipment and a storage medium, and the method comprises the steps: obtaining the input voltage of a motor and the feedback rotation speed of the motor; wherein the feedback rotating speed is the rotating speed fed back to the speed control ring by the motor; calculating an estimated current according to the input voltage and the feedback rotating speed; determining whether the driving current of the motor is abnormal or not according to the estimated current and feedback current output by the motor; wherein the feedback current is the current fed back to the current control loop by the motor. The input voltage of the motor and the feedback speed fed back to the speed control loop are acquired in real time to calculate the real-time estimated current, and the real-time estimated current is compared with the feedback current fed back to the current control loop by the motor to quickly and accurately determine whether the driving current of the motor is abnormal or not.
