Abstract

The present disclosure relates to a computer system and a method for controlling pressure release in a liquid gas fuel volume of a vehicle, the vehicle including a liquid gas fuel volume, a valve controllable to ventilate a volume of fuel gas into ambient surroundings of the vehicle, a sensor assembly, a navigational system and a computer system including a processor device. The method includes, by the processor device identifying the vehicle approaching a confined space, measuring by the sensor assembly a status of the liquid gas fuel volume. Based on the measured status of the liquid gas fuel volume and on historical data, estimating an amount of fuel gas that would be released while the vehicle is located in the confined space, and controlling the valve to preemptively ventilate at least the estimated amount of fuel gas from the liquid gas fuel volume before reaching the confined space.

First claim

1 . A computer system comprising a processor device for controlling pressure release in a liquid gas fuel volume of a vehicle, the vehicle comprising a liquid gas fuel volume, a valve controllable to ventilate a volume of fuel gas into ambient surroundings of the vehicle, a sensor assembly and a navigational system, the processor device being configured to:
identify the vehicle approaching a confined space, measure by the sensor assembly a status of the liquid gas fuel volume, based on the measured status of the liquid gas fuel volume and on historical data, estimate an amount of fuel gas that would be released while the vehicle is located in the confined space, and controlling the valve to preemptively ventilate at least the estimated amount of fuel gas from the liquid gas fuel volume before reaching the confined space.

2 . A computer-implemented method for controlling pressure release in a liquid gas fuel volume of a vehicle, the vehicle comprising a liquid gas fuel volume, a valve controllable to ventilate a volume of fuel gas into ambient surroundings of the vehicle, a sensor assembly, a navigational system and a computer system comprising a processor device, the method comprising, by the processor device:
identifying the vehicle approaching a confined space, measuring by the sensor assembly a status of the liquid gas fuel volume, based on the measured status of the liquid gas fuel volume and on historical data, estimating an amount of fuel gas that would be released while the vehicle is located in the confined space, and controlling the valve to preemptively ventilate at least the estimated amount of fuel gas from the liquid gas fuel volume before reaching the confined space.

3 . The method of claim 2 , further comprising continuously or intermittently collecting data on a group of confined spaces, and wherein the confined space that the vehicle is approaching is comprised in the group of confined spaces.

4 . The method of claim 3 , wherein the data on confined spaces relate to one or more of: type of confined space, ambient temperature, ambient pressure, location and/or time spent by the vehicle in the confined space.

5 . The method of claim 3 , wherein the data on confined spaces is collected by the sensor assembly, by a Global Positioning System/Global Navigation Satellite System (GPS/GNSS), by communication with a remote database, and/or by collection of navigational data from the navigational system.

6 . The method of claim 3 , further comprising storing the collected data on confined spaces as historical data.

7 . The method of claim 2 , wherein measuring the status of the liquid gas fuel volume comprises measuring one or more of: a temperature of the liquid fuel gas volume, a pressure of the liquid fuel gas volume, an ambient pressure and/or an ambient temperature.

8 . A vehicle comprising a processor device, a liquid gas fuel volume, a valve controllable to ventilate a volume of fuel gas into ambient surroundings of the vehicle, a sensor assembly and a navigational system, the processor device being configured to perform a method comprising:
identifying the vehicle approaching a confined space, measuring by the sensor assembly a status of the liquid gas fuel volume, based on the measured status of the liquid gas fuel volume and on historical data, estimating an amount of fuel gas that would be released while the vehicle is located in the confined space, and controlling the valve to preemptively ventilate at least the estimated amount of fuel gas from the liquid gas fuel volume before reaching the confined space.
