The invention provides a vehicle differential protection method, device and equipment, a storage medium and a vehicle. The method comprises the steps that whether a driving shaft connected with a differential mechanism is damaged or not is judged based on wheel speeds at the two ends of the differential mechanism and the motor rotating speed of a vehicle motor; in response to determining that the drive shaft is damaged, determining a first wheel speed difference between wheels at two ends of a differential by using the motor speed; and the duration time when the first wheel speed difference is larger than or equal to a pre-calibrated wheel speed difference threshold value is determined, and the output torque executed by the driving shaft is determined based on the duration time and the first wheel speed difference so as to protect the differential mechanism. Therefore, according to the method, the torque applied to the differential mechanism under different driving shaft conditions is limited, and the protect
