Automatic fueling notification
View Patent ↗A system that notifies the operator, during refueling, when the fuel tank of a vehicle has been filled to contain a predetermined amount. The predetermined amount may include but is not limited to a full condition, an amount that is calculated to satisfy a specific trip, etc. The system may include one or more fuel sensors that can detect conditions of the fuel delivery system, such as the quantity of fuel residing in the tank. The system further includes a controller and an output device. During a refill event, the controller receives the data from the one or more sensors, processes the data, and causes the output device to notify the operator when the tank is filled with the predetermined amount of fuel. The notification can be audible, such as the horn honking, visual, such as lights flashing, or tactile, such as the vehicle seat vibrates.
1. A system for notifying a user of a condition during refueling of a vehicle, comprising:
an output device configured to produce a user notification;
a fuel reservoir;
a memory having stored therein a start quantity of fuel in the fuel reservoir, a full quantity of fuel in the fuel reservoir, and a user-selectable quantity of fuel in the fuel reservoir;
one or more sensors associated with the fuel reservoir, wherein the one or more sensors are configured to generate data indicative of a cumulative quantity of fuel added to the fuel reservoir; and
a controller configured to receive the data from the one or more sensors during refill of the fuel reservoir, add the cumulative quantity to the start quantity to determine a total quantity of fuel in the fuel reservoir, compare the total quantity of fuel in the fuel reservoir with the full quantity of fuel in the fuel reservoir or the user-selectable quantity of fuel in the fuel reservoir, and cause the output device to produce the user notification when the total quantity of fuel in the fuel reservoir has exceeded either the full quantity of fuel in the fuel reservoir or the user-selectable quantity of fuel in the fuel reservoir.
2. The system of claim 1 , wherein the output device generates one of an audible notification, a visual notification, and a haptic notification.
3. The system of claim 1 , wherein the data indicates one or more conditions selected from the group consisting of fuel volume, fuel weight, and fuel level.
4. The system of claim 1 , wherein the user-selectable quantity of fuel in the fuel reservoir is less than a quantity representing a full fuel reservoir.
5. The system of claim 1 , wherein the user-selectable quantity of fuel represents a quantity of fuel required to reach a selected destination.
6. The system of claim 1 , further comprising a start switch.
7. The system of claim 6 , wherein the start switch is a user operated switch.
8. The system of claim 6 , wherein the start switch is activated by a signal generated by one of the one or more sensors.
9. The system of claim 6 , wherein the start switch is activated by a signal generated by a sensor independent of the one or more sensors.
10. A method for notifying a user of a condition during refueling of a vehicle, comprising:
storing, in a memory, values indicating a start quantity of fuel in a fuel tank, a full quantity of fuel in the fuel tank, and a user-selectable quantity of fuel in the fuel tank;
receiving data indicative of a fuel level in the fuel tank from one or more sensors;
obtaining, from the memory, the values indicating the full quantity of fuel in the fuel tank and the user-selectable quantity of fuel in the fuel tank;
determining a cumulative quantity of fuel added to the fuel tank during refueling from the one or more sensors;
determining a total quantity of fuel in the fuel tank during refueling by adding the cumulative quantity of fuel to the start quantity of fuel;
comparing the total quantity of fuel in the fuel tank with the full quantity of fuel in the fuel tank or the user-selectable quantity of fuel in the fuel tank; and
outputting a notification signal in response to the total quantity of fuel in the fuel tank being equal to or greater than the full quantity of fuel in the fuel tank or the user-selectable quantity of fuel in the fuel tank.
11. The method of claim 10 , wherein the notification signal is one of an audible signal, a visual signal, and a haptic signal.
12. The method of claim 10 , wherein the data is generated from one or more sensors selected from a group consisting of a load sensor, a fuel flow meter, a float sensor, and a distance sensor.
13. The method of claim 10 , wherein the user-selectable quantity of fuel in the fuel tank represents a minimum quantity of fuel needed to reach a destination.
14. The method of claim 10 , wherein the user-selectable quantity of fuel in the fuel tank is less than a quantity representing a full tank.
15. The method of claim 10 , wherein determining the quantity of fuel in the fuel tank during refueling includes:
determining a quantity of fuel added to the fuel tank during refueling; and
adding to the quantity of fuel added to the fuel tank during refueling the start quantity of fuel in the fuel tank.
