The invention relates to a method for refuelling a vehicle (60) or an autonomous vehicle (60). At least one hydrogen tank (10) accommodating gaseous hydrogen is fitted in the vehicle (60). The method comprises the following method steps: The vehicle (60) drives into a refuelling area (24). A refuelling operation (28; 78, 80, 82) is performed on the vehicle (60). Then, the temperature of the contents of the at least hydrogen tank (10) is checked (30). If a temperature (74) of the tank contents of the at least one hydrogen tank (10) exceeds a temperature limit value (32), the vehicle (60) is transferred to a cooling down area (36). There, the tank temperature (44) is checked a second time following a cooling down phase. The tank pressure is checked (48) if the tank temperature (74) lies below a temperature limit value. If the tank pressure (76) in the at least one hydrogen tank (10) is below a tank pressure limit value, the vehicle (60) is transferred to the refuelling area (24) to continue refuelling; if the tank pressure (76) is in the tank pressure limit range, refuelling is halted (52).
