Abstract

The disclosure relates to a computer-implemented method (10) for controlling pressure release in a liquid gas fuel volume (20) in a vehicle (30), the liquid gas fuel volume (20) being arranged with a control unit (24) and a pressure release valve (22) configured to automatically ventilate gas to an external environment when a pressure in the liquid gas fuel volume (20) exceeds a predetermined ventilation set point (P<T>). The method (10) comprises obtaining (S1) by the control unit (24) data, which data pertains to operation of the vehicle and to historical automatic ventilation events of the liquid gas fuel volume (20), determining (S2) by the control unit (24) a refueling pressure set point (R<P>) for the liquid gas fuel volume (20) based on the obtained data, and at a subsequent refueling operation R, communicating (S3) the refueling pressure set point as a maximum pressure threshold to be used when refueling the liquid gas fuel volume (20). The disclosure also relates to a control unit (24) to control pressure release according to the method (10), a computer program, a computer-readable medium, a liquid fuel gas volume (20) arranged with the control unit (24) and a vehicle (30) comprising the liquid fuel gas volume.
