TLDR
In this article, a method for a vehicle, comprising: indicating a true fill level of a fuel tank based on a fuel vapor canister temperature profile during a refueling event, was proposed.Abstract:
A method for a vehicle, comprising: indicating a true fill level of a fuel tank based on a fuel vapor canister temperature profile during a refueling event. In this way, a quantity fuel dispensed over the maximum fill level of the fuel tank may be accounted for, regardless of the fuel level sensor reading.read more

System and methods for determining fuel fill level
Dudar Aed M,Chingpo Liu +1 more
TL;DR: In this article, the initial rate of change of fuel tank pressure is proportional to the amount of vapor dome space within the fuel tank, and thus proportionate to the residual fuel left in the tank.
Patent
Reductant tank sensor diagnostic method and system
TL;DR: In this paper, a system for diagnosing a sensor of an exhaust aftertreatment system may include receiving a first tank level value from a sensor, which is then determined based on the difference between the sensor-estimated dosing value and the second tank level values.
Patent
Method for controlling a filling operation of a vehicular liquid storage system.
TL;DR: In this paper, a method for controlling a filling operation of a vehicular liquid storage system comprising a tank equipped with a fill level limiting valve is presented, which includes detecting the start of a first filling event, measuring a first fill level of said tank, verifying whether said measured first filllevel has reached a predetermined fill level; if said verifying is positive, starting a first timer for a first amount of time; upon expiry of said first timer, closing said fill level restricting valve.
Patent
Fluid level indication for vehicle reservoirs
TL;DR: In this article, a system and method for estimating a fluid level in a reservoir disposed in a vehicle compartment having a compartment cover is presented, which includes monitoring at least one operational parameter relating to the reservoir, monitoring a state of the compartment cover using a sensing device, detecting a triggering event, and in response, determining an estimate for an amount of fluid in the reservoir based on data related to the triggering event.
