Abstract
A method grants an enablement of refueling of a motor vehicle. The method includes the steps: i) detecting a tank temperature value which is indicative of the present temperature of at least one pressure vessel of the motor vehicle and/or of the fuel stored in the at least one pressure vessel; ii) determining a temperature difference value which is indicative of the present difference between the tank temperature value and an ambient temperature value which is indicative of the ambient temperature; and iii) releasing a tank flap, wherein the tank flap is released by the motor vehicle for the purposes of refueling only if the temperature difference value is lower than a temperature difference threshold value.
Claims11
A method for granting an enablement of refueling of a motor vehicle, the method comprising:
- detecting a tank temperature value which is indicative of a present temperature of at least one pressure vessel of the motor vehicle and/or of fuel stored in the at least one pressure vessel;
- determining a temperature difference value which is indicative of a present difference between the tank temperature value and an ambient temperature value which is indicative of ambient temperature;
- and
- releasing a tank flap, wherein the tank flap is released by the motor vehicle for the purposes of refueling, only if the temperature difference value is lower than a temperature difference threshold value.
A method for refueling a motor vehicle, the method comprising:
- releasing a tank flap as a result of granting of an enablement of refueling by:
- detecting a tank temperature value which is indicative of a present temperature of at least one pressure vessel of the motor vehicle and/or of fuel stored in the at least one pressure vessel;
- determining a temperature difference value which is indicative of a present difference between the tank temperature value and an ambient temperature value which is indicative of ambient temperature, wherein the tank flap is released by the motor vehicle purposes of refueling, only if the temperature difference value is lower than a temperature difference threshold value;
- and
- refueling the motor vehicle taking into consideration the ambient temperature value.
A motor vehicle having a pressure vessel system, comprising:
- at least one pressure vessel;
- at least one tank flap;
- and
- at least one control unit, wherein the control unit is configured to:
- detect a tank temperature value which is indicative of a present temperature of the at least one pressure vessel and/or of fuel stored in the at least one pressure vessel,
- determine a temperature difference value which is indicative of a present difference between the temperature value and an ambient temperature value which is indicative of ambient temperature, and
- release the tank flap by the motor vehicle for purposes of refueling only if the temperature difference value is lower than a temperature difference threshold value.
