In the event of an abnormality occurring in a temperature sensor that is used to detect the temperature of a battery, an electrically driven vehicle sets a drivable time by using a reference temperature of the battery and gives permission for emergency drive until a driving time of the electrically driven vehicle reaches the drivable time. When the reference temperature is used for the first time since the occurrence of the abnormality in the temperature sensor, a temperature detected before the occurrence of the abnormality in the temperature sensor is used as the reference temperature. When the reference temperature is used for the second or subsequent time since the occurrence of the abnormality in the temperature sensor, a temperature obtained by applying a resistance value based on an inter-terminal voltage of the battery and an electric current flowing in the battery, to a correlation between battery resistance and battery temperature is used as the reference temperature.
