Abstract:
Described herein is a computer-implemented method for estimating a true fuel level of a vehicle. The method comprises: accessing an estimate as to a current state of the vehicle, the current state of the vehicle comprising a current fuel level state; predicting the state of the vehicle at a future time based on the current state of the vehicle; accessing a measured state of the vehicle based on sensor data; estimating a true state of the vehicle based on the predicted state of the vehicle and the measured state of the vehicle, the true state of the vehicle comprising an estimate as to the true fuel level of the vehicle; and outputting the estimated true fuel level of the vehicle.
Abstract:
Device, system, and method for wirelessly communicating a fuel level of a fuel tank to a TRS controller. The electronics of the fuel level sensor, which include a temperature sensor for measuring ambient temperature, are completely sealed and protected from the elements. The fuel level sensor can quickly connect and disconnect to a mechanical floater assembly and/or a fuel tank.
Abstract:
Present invention optimizes utilization of different fuels in various single and multi-fueled engines. The fuel system and optimization controller links fuel properties (physical, reactionary, combustion etc.) to on-board computer systems during the refueling process. This link enables fuel and additive producers an opportunity to optimize combustion parameters of their proprietary fuel blends to increase performance, fuel efficiencies and reduce emissions.

L'invention concerne un procédé de contrôle d'une mesure de pression dans un réservoir de carburant, mis en œuvre dans un véhicule comprenant un réservoir de carburant, et un circuit d'évacuation de vapeurs de carburant comportant : · un filtre, · une vanne d'isolation du réservoir, interposée entre le réservoir et le filtre, et · une ligne de purge, reliée au filtre, en aval de celui-ci, et comprenant un capteur de pression, et une vanne de purge, le procédé comprenant des étapes, lorsque la vanne de purge est fermée, de : · mesure (100) d'une valeur de pression dans le réservoir lorsque la vanne d'isolation est fermée, puis · mesure (200) d'une valeur d'extremum temporel de pression dans la ligne de purge suite à une ouverture de la vanne d'isolation, et · détermination (300), à partir des valeurs mesurées, d'une anomalie dans la pression mesurée dans le réservoir.
Abstract:
A vehicle (100) includes a fuel tank (14), a fuel amount detecting device and a control device (24). The fuel amount detecting device (33) is configured to detect an amount of fuel inside the fuel tank (14). The control device (24) is configured to calculate an estimated refueling amount that diminishes fuel inside the fuel tank (14) from degrading based on a usage history of the vehicle (100). The control device (24) is further configured such that the control device (24) stops refueling based on an amount of fuel detected by the fuel amount detecting device (33) and the estimated refueling amount.
Abstract:

The present invention further relates to use of a system for spill-free refilling of liquids and also to a gun for spill-free refilling of liquids, a connection for a vehicle tank, a method and a system for control and communication in a spill-free liquid re-filling system, a method and a system for media provision in a spill-free refilling system, a spill-free and liquid-tight refilling connection and computer programme products.
Abstract:
A self-closing cap (50) for the filling neck of a container, the self-closing cap having integral therewith a smart card (54) having a container coil antenna (52) for communicating with a supply station coil antenna fixed to a supply nozzle when the supply nozzle is inserted into the container through the self-closing cap.
Abstract:
A fuel tank system according to the present disclosure includes a fuel tank, a purge canister a valve assembly and a controller. The valve assembly has an upstream canister valve that moves between an open position and a closed position to close an upstream vent line that fluidly connects the fuel tank and the purge canister. The controller (i) conducts a first pressure test that measures a pressure in the fuel tank over a time, (ii) closes the upstream canister valve based on a determination that a leak exists, (iii) conducts a second pressure test that measures a pressure in the fuel tank over a time subsequent to closing the upstream canister valve and (iv) determines a location of the leak based on comparing the first pressure test and the second pressure test.
