Abstract: A method for controlling a pressure inside a fuel tank system on board a vehicle, the fuel tank system having a fuel tank and a venting circuit having at least one controllable pressure relief valve, the vehicle having a source of energy adapted to activate said at least one pressure relief valve so as to move it from a closed position to a pressure relief position. The method entails: detecting a key off event indicative of the vehicle shut-down; determining an amount of energy available at the source of energy; starting at least one pressure relief operation by verifying whether the amount of energy available is lower than a first predetermined threshold amount and, if the verification is positive, activating the at least one pressure relief valve; and terminating the at least one pressure relief operation.

Abstract: A method for determining the volatility of fuel in a fuel storage system which entails: determining that a refueling event has occurred (210) and that the fuel storage system has subsequently been sealed (220); performing a first pressure measurement (230) at a first time after the determining; performing a second pressure measurement (240) at a second time, the second time occurring after the first time; determining a pressure evolution rate (250) from the first pressure measurement at the first time and the second pressure measurement at the second time; and deriving an estimation (260) of the volatility of the fuel from the pressure evolution rate.

Abstract: Fuel tank (1) having: a wall (12) defining an internal volume (20) of the tank, and a temperature sensor (4) located inside the internal volume of the tank and at least partially enveloped with a material (21) having a thermal diffusivity comprised between 2×10−7 and 2×10−5 m2/s at 20° C. The temperature sensor measure an internal tank temperature, such as a vapor dome temperature.

Abstract: Determining the thermodynamic state of fuel includes opening the venting connection to release the tank pressure while monitoring the derivative pressure (dP/dt), closing the venting connection when one of the following conditions is met, the derivative pressure (dP/dt) is lower than a predetermined threshold DP1 or the opening time Δt1 reaches a predetermined value, if the closing of the venting connection occurs when the opening time Δt1 reaches the said predetermined value, determining that the fuel is boiling and aborting the method if the closing of the venting connection occurs when the derivative pressure (dP/dt) is lower than the said threshold DP1, measuring an initial tank pressure at the closing of the venting connection, measuring the final tank pressure after a closure time Δt2, calculating the pressure variation (ΔP/Δt2), comparing the pressure variation (ΔP/Δt2) with a first threshold PV1, if the pressure is lower then aborting the method.

Abstract: A method for controlling a filling operation of a vehicular liquid storage system including a tank equipped with a filler pipe and a shut-off valve, the method including detecting the start of a refilling event; while the shut-off valve is open, observing whether a measured fill level of the tank has reached a predetermined fill level; if the predetermined fill level has been reached, performing the following steps: closing the shut-off valve to induce a shut-off of a filling nozzle; when a first pressure criterion is met, opening the shut-off valve; and when a second pressure criterion is met, closing the shut-off valve. The second pressure criterion includes a decrease of pressure inside the tank below a predetermined pressure level.
