  • A METHOD FOR TESTING THE STATE OF AT LEAST ONE INTERNAL REINFORCEMENT ELEMENT OF A LIQUID TANK OF A VEHICLE
    Publication number: 20210164861
    Abstract: A method tests the state of an internal reinforcement element connecting two opposed walls of a liquid tank including an initial amount of liquid measurable by a level sensor. The method includes: determining a first threshold based on the initial amount of liquid and an initial internal pressure of the liquid tank; monitoring a level sensor output and a pressure sensor output; if the pressure sensor output is above the first threshold, determining a second threshold and a third threshold; comparing the level sensor output to the second and third thresholds; if the level sensor output is above the second threshold, sending a first predetermined signal indicating that the internal reinforcement element is broken, and/or if the level sensor output is below a third threshold, sending a second predetermined signal indicating that the internal reinforcement element is broken.
