| 摘要 |
It is proposed a vehicular liquid containment system comprising a tank (1), a pressure sensor (7) arranged to detect a pressure in a vapor dome inside the tank (1), a thermistor array (2) arranged to detect temperatures at a plurality of levels of the tank (1), and leak detection logic operatively connected to the pressure sensor (7) and the thermistor array (2). The leak detection logic is configured to:
- use a first thermistor (3") of the thermistor array (2) to perform a first measurement indicative of a temperature in a vapor dome in the tank (1);
- estimate an expected pressure evolution in function of at least the first temperature measurement;
- monitor pressure sensed by the pressure sensor (7),
- determine whether the monitored pressure deviates from the expected pressure evolution, and
- generate a leak condition signal, conditional on said determining. |
