Zusammenfassung:	The present application relates to the field of electric vehicles. Disclosed are a distance to empty determining method and apparatus. The method comprises: acquiring an actual driving attenuation coefficient of the last travel; in the process of the current travel, according to a preset display period, acquiring a current state of charge (SOC) of a vehicle battery corresponding to a current display period, an influence coefficient corresponding to current vehicle operation information, and an influence coefficient corresponding to current battery operation information; and according to the actual driving attenuation coefficient, the current SOC and a preset full-charge distance to empty, the influence coefficient corresponding to the current vehicle operation information, and the influence coefficient corresponding to the current battery operation information, determining an actual distance to empty corresponding to the current display period. The use of the present application can improve the accuracy of ca
