Description

VEHICLE FUELING MANAGEMENT SYSTEM
BACKGROUND OF THE INVENTION 1. Field of the invention. The present invention relates to a device for dispensing liquid fuel. More particularly, the present invention relates to a fuel dispenser having a sealed fuel delivery conduit and a sealed vapor receiving conduit, which receives an initial communication from a target vehicle. 2. Description of the related art.
Fuel dispensing stations generally include an above-ground monitoring and controlling device having an extendable hose with an attached nozzle for dispensing fuel into an awaiting vehicle. The above-ground device often times provides an operator with a means of inserting a credit card and receiving pre-approval on the fuel intended to be dispensed. Additionally, the operator must select a grade of fuel .
Once the above-mentioned selections have been made, fueling can commence, and fuel is dispensed through the hose into the fuel tank of the vehicle. Simultaneously, vapors housed within the fuel tank are displaced into the immediate atmosphere as the fuel continues to enter the fuel tank. This release of vapors into the atmosphere has been a cause of concern for numerous environmental entities and governing bodies. Furthermore, it is this transfer of fuel vapor from the fuel tank to the atmosphere that inhibits the flow of fuel into the fuel tank. It is therefore desirable to provide a fuel dispensing system that offers an environmentally conscious rapid fueling capability.
SUMMARY OF THE INVENTION The present invention provides a fuel dispensing system that delivers fuel to a fuel inlet port of a target vehicle in a rapid and environmentally friendly manner. According to the invention, the fuel dispensing system includes a fuel dispenser having a pump means, a nozzle having a fuel dispensing port and a vapor receiving port, a hose disposed between the fuel dispenser and the nozzle for carrying fuel to the vehicle and recovering vapor from the vehicle, a coupling assembly for creating a sealing relationship between the nozzle and the fuel inlet port, a data storage device attached to the vehicle, a communications assembly for transmitting signals between the fuel dispenser and the data storage device prior to the activation of the pump, and a processor assembly for receiving, processing, and sending signals to control fuel dispensing activity in accordance with the processing results.
The fuel dispensing system, in one form thereof, defines a first communicating element associated with a fuel dispenser and a second communicating element associated with the vehicle. Prior to fueling, the first and second communicating elements transfer signals representative of the vehicle identification, customer payment data, and refueling grade data. Upon the successful transfer of the representative signals, an operator is given permission to commence fueling of the desired transmitted grade of fuel, and applicable charges are applied to the customer's designated credit card.
The invention, in another form thereof, provides a method of delivering fuel to and removing vapors from a vehicle carrying refueling information, the method comprising the steps of communicating the refueling information to a receiver, processing the refueling information, removably and sealingly engaging a fluid delivery conduit and a vapor recovery conduit to the vehicle, detecting for leaks in the fluid delivery conduit and the vapor receiving conduit, providing fuel through the fuel delivery conduit and providing a vapor vacuum through the vapor recovery conduit .
It is an advantage of the present invention that a vehicle operator need not enter his credit card information each time he fills up his vehicle with fuel.
It is a further advantage of the present invention that the nozzle attached to the fuel dispensing system includes both a fuel dispensing port and a vapor receiving port, for eliminating the release of fuel vapors into the surrounding environment during refueling.
It is another advantage of the present invention that the vapor receiving port is provided with a vacuum device for creating a vacuum in the vapor receiving port and attached vapor recovery conduit, thereby providing for the quick and efficient removal of vapors from the vehicle's fuel tank. By providing the quick and efficient removal of vapor from the fuel tank, fuel may be dispensed at a higher flow rate, thereby shortening the total time necessary to fill a fuel tank. It is yet another advantage of the present invention that a sealing relationship is established between the fuel dispenser and the fuel tank of the vehicle via a coupling arrangement that includes a first coupling element sealingly attached to the nozzle of the fuel dispenser and a second coupling element that is fitted to sealingly attach to a fuel inlet port, the first and second coupling elements having a mating relationship with each other. By providing for a sealing relationship between all components, the present invention provides for a transfer of fluid into the fuel tank and the transfer of vapors back to the fuel dispensing system while preventing any leakage or loss of the fuel and vapor to the environment. Additionally, this allows for refueling without leaving fuel residue on the hands of the operator of the fuel dispenser.
A further advantage of the present invention is the ability to detect a leak or improperly connected coupling assembly within the fuel and vapor conduits. When a leak is detected, a processor assembly alerts an operator, and ceases operation of the pumping mechanism until a sealing relationship is established. It is a further advantage that the coupling assembly includes quick-connect intermeshing coupling elements for facilitating easy and efficient attachment by an operator.
It is still a further advantage of the present invention that a credit authorization is performed while the seal check is initiated to ensure secure connection between the nozzle coupling and the fuel tank coupling, thereby shortening fueling time.

Fig. 3 is an enlarged, cross-sectional view of the coupling device associated with the invention; and
Fig. 4 is a diagrammatic view of a typical fuel dispensing apparatus that includes another type of quick fill device according to the present invention.
Corresponding reference characters indicate corresponding parts throughout the several views. The exemplification set out herein illustrates one preferred embodiment of the invention, in one form, and such exemplification is not to be construed as limiting the scope of the invention in any manner. DETAILED DESCRIPTION OF THE INVENTION Referring now to the drawings and particularly to Fig. 1, there is shown a fuel dispensing system 10 having a fuel dispenser 11, a pump means 48 for pumping fuel to a vehicle 22, a hose 12, a nozzle 14, nozzle coupling element 16 and fuel tank coupling element 18 for sealingly engaging nozzle 14 with a fuel inlet port 20 on vehicle 22.
As shown in Fig. 2, hose 12 is comprised of a fuel delivery conduit 24, a fuel dispensing port 25, a vapor recovery conduit 26 and vapor receiving port 27. Both fuel delivery conduit 24 and vapor recovery conduit 26 being operatively connected to nozzle coupling element 16 (shown in Fig. 3) .
Fig. 3 portrays the relationship between hose 12, nozzle coupling element 16, and fuel tank coupling element 18. Hose 12 carries fuel delivery conduit 24, fuel dispensing port 25, vapor recovery conduit 26 and vapor receiving port 27, and hose 12 sealingly engages nozzle 14 such that no leakage can occur between hose 12 and nozzle 14, and between fuel delivery conduit 24 and vapor recovery conduit 26. While Fig. 3 shows delivery conduit 24 and recovery conduit 26 concentrically aligned, it is within the scope of the invention to have any alignment for conduits 24, 26, including a side-by-side relationship. Fuel dispensing system 10 is utilized with a vacuum assisted vapor recovery system but is not limited to a vacuum assisted vapor recovery system and other systems, such as a balance system for vapor recovery, can be utilized as well. Nozzle coupling element 16 is formed to have a sealing and mating relationship with fuel tank coupling element 18, such that vapor and fuel are prevented from leaking into the atmosphere . Nozzle coupling element 16 and fuel tank coupling element 18 are dry brake couplings wherein when the coupling is broken, each of coupling elements 16 and 18 seal themselves so no fuel can escape and no vapor can escape. An example of dry brake couplings would be flapper valves. The invention is not limited to dry brake couplings and other types of couplings may be utilized as well. Directional arrows 17 show the insertion of nozzle coupling element 16 into fuel tank coupling element 18.
Fig. 3 also shows a threaded coaxial quick-connect and quick- disconnect relationship between nozzle coupling element 16 and fuel tank coupling element 18. The quick connect/disconnect coupling allows for nozzle 14 to be securely fastened into fuel inlet port 20 of vehicle 22 with one turn of nozzle 14. This is just one example of the relationship between nozzle coupling element 16 and fuel tank coupling element 18 and is not meant to be limiting to the invention. It is within the scope of the invention to have any sealing and mating relationship between coupling elements 16, 18, including other quick-connect and quick- disconnect embodiments, such as a releasable collar. The sealing and mating relationship between coupling element 16, 18 can also be much like that utilized to fuel a race car or an airplane. In another embodiment of the present invention, a removable sealing and mating relationship between nozzle coupling element 16 and fuel tank coupling element 18 is an interlocking relationship.
In one embodiment of the present invention, as shown in Fig. 4, the trigger is removed from nozzle 14 since the flow rate is determined by the operator selecting fueling options from a display (not shown) , such as a touch screen display, located on either nozzle 14 or fuel dispenser 11. Either a preset amount of money or gallons of fuel can be entered, as well as, the option to fill the fuel tank of vehicle 22. Another way to select the fueling options on nozzle 14 would be to rotate thumb wheels corresponding to either the total amount of fuel desired to be purchased, the total number of gallons of fuel to be purchased, or to completely fill the fuel tank. Also, a button can be utilized on nozzle 14, and when that button is pressed, fuel dispenser 11 will completely fill the fuel tank of vehicle 22. Other ways of designing nozzle 14 to allow for selecting fueling options can be utilized as well. Other designs for nozzle 14 can be utilized such as nozzle designs much like that utilized for filling race cars or airplanes with fuel. Also, the amount of fuel can be manually controlled by the operator utilizing a standard nozzle utilizing a flow controlling device, such as a trigger. Fuel tank coupling element 18 is formed such that it can be engaged to an existing fuel tank inlet port 20, thereby converting a standard fuel tank inlet port 20 into a quick-connecting sealable coupling element. In one embodiment, fuel tank coupling element 18 is a filler cap that fits onto fuel tank inlet port 20. In another embodiment, fuel tank coupling element 18 remains with the vehicle between fueling stations, allowing for refueling to be accomplished without the extra step of attaching and unattaching fuel tank coupling element 18 each time. In one embodiment, fuel tank coupling element 18 fits onto a filler pipe 46 located in the fuel tank of vehicle 22. Fuel tank coupling element 18 does not have to be fit onto filler pipe 46 and can be placed in or on other locations of vehicle 22.
In one embodiment of the invention, as shown in Fig. 1, a data storage device 28 is attached to vehicle 22 in close proximity to fuel inlet port 20. The location of data storage device 28 is not to be limited by Fig. 1 and other locations for data storage device 28 such as inside the fuel tank of vehicle 22 can be utilized as well. Data storage device 28 stores information pertaining to vehicle 22 including the make and year of vehicle 22, the size of the fuel tank for vehicle 22, customer payment information such as a credit card number, and the customer's desired grade of fuel. Payment information is not limited to credit card information and any payment card such as an Automated Teller Machine card or a debit card. Also, a bank account number can be utilized to directly withdraw payment for the fueling transaction directly from the bank account. The frequency and dollar amount of fueling transactions by the owner of vehicle 22 can be stored on data storage device 28. Fuel dispenser 11 or one of its components will read the data from data storage device 28 and based on the frequency and dollar amount of the fueling transactions made by the owner of vehicle 22 for a predetermined amount of time, a discount, coupon or other reward can be given to the owner of vehicle 22 based on a frequent buyer program or other promotional program.
In another embodiment of the present invention, data storage device 28 is located within fuel tank coupling element 18. Data storage device 28 is one or more integrated circuits such as Electrically Erasable Programmable Read Only Memory. Other types of memory to store the information pertaining to vehicle 22 can be utilized as well.
The information pertaining to vehicle 22 is encrypted to stop people from attempting to retrieve the owner's credit card information from data storage device 28. Furthermore, if data storage device 28 is removed from vehicle 22 after installation, a security means 50 causes the integrated circuits or other memory to be erased or unaccessible to eliminate the possibility of theft of data storage device 28 and utilizing data storage device 28 to illegally dispense fuel into another vehicle utilizing the credit card information for the owner of data storage device 28. In one embodiment of the present invention, fuel tank coupling element 18 has a battery and a strip of conductive material connected to the battery. The strip of conductive material has an adhesive exterior. Also located in fuel tank coupling 18 is data storage device 28. The adhesive strip of conductive material is located above data storage device 28. When fuel tank coupling element 18 is placed in fuel tank inlet port 20, filler pipe 46 moves into the interior of fuel tank coupling element 18. Once fuel tank coupling element 18 is completely connected to filler pipe 46, the strip of conductive material sticks to the end of filler pipe 46. If fuel tank coupling element 18 is removed from filler pipe 46, the strip of conductive material continues to adhere to filler pipe 46 and before fuel tank coupling element 18 is completely removed from filler pipe 46, the strip of conductive material comes into contact with data storage device 28 with enough electricity to erase data storage device 28. The strip of conductive material sticks to the bottom of fuel tank coupling element 18 once fuel tank coupling element 18 is completely removed from filler pipe 46 to eliminate the need of having to remove the strip of conductive material from filler pipe 46 once fuel tank coupling element 18 is completely removed. Other ways of making data storage device 28 unaccessible if removed from vehicle 22 can be utilized as well.
Data storage device 28 can be purchased from a store and at that store, the purchaser provides the vehicle and credit card information to the store worker to have the information stored on data storage device 28. Once data storage device 28 is programmed, the operator attaches data storage device 28 to vehicle 22 and the operator can utilize the fuel dispenser system 10 to quickly fill the fuel tank of vehicle 22. Also, the operator of vehicle 22 can buy a new data storage device 28 and attach data storage device 28 to vehicle 22 without programming data storage device 28. The first time the operator attempts to refuel vehicle 22, signal receiver 34 will interrogate data storage device 28 and upon being unable to find any data on data storage device 28 to quickly fill the fuel tank of vehicle 22, signal receiver 34 will send a signal to processor assembly 30. Processor assembly 30 will send a signal to the display (not shown) on fuel dispenser 11 and/or to a speaker (not shown) on fuel dispenser 11 to notify the operator either visually and/or audibly to go into the service station to provide the pertinent information and the worker in the service station will be able to store the vehicle and credit card information on data storage device 28.
In one embodiment of the invention, communicating element 32 transmits data from data storage device 28 to signal receiver 34 using radio frequency (RF) signals. However, other embodiments are anticipated by this invention, including a direct electrical connection between data storage device 28, communicating element 32 and processor assembly 30 wherein a serial transmission link connection is established when a mating relationship is formed between coupling elements 16, 18. Another way to transmit between data storage device 28 and signal receiver 34 is to place an magnetic ring around filler pipe 46 and another ring around nozzle 14. When the two rings get close to one another, they become magnetically coupled. The data from storage device 28 can then be interrogated from communicating element 32 by signal receiver 34. Signal receiver 34 is in wireless bi-directional communication with processor assembly 30. The wireless communication can be by RF signals or any other wireless communication signal . Other ways of communicating data between data storage device 28 and signal receiver 34 can be utilized as well. The location of signal receiver 34 as shown in Fig. 3 is one embodiment of the present invention. Signal receiver 34 can be located anywhere on the fuel dispenser and/or any of fuel dispenser 11 components. A data input device 42 is utilized for receiving alternative operator payment data and refueling grade data and transmitting the data to processor assembly 30. Processor assembly 30 processes the data received from data input device 42 and controls the fuel dispensing activity in accordance with the processing results. Processor 30 then transmits the data to communicating element 32 to store the data to data storage device 28.
In one embodiment of the present invention, communicating element 32 and data storage device 28 are located within or close to fuel tank coupling element 18. Fuel tank coupling element 18 can be shaped much like a filler cap with communicating element 32 and data storage device 28 located within fuel tank coupling element 18. In another embodiment of the present invention, communicating element 32 and data storage device 28 are located in fuel tank coupling element 18. Fuel tank coupling element 18 can be an identical shape to a standard filler cap.
Fuel dispensing system 10 additionally comprises a leak check assembly 36 located in fuel dispenser 11, for detecting a sealing relationship between coupling elements 16, 18. Leak check assembly 36 provides a signal to processor assembly 30 to cease the dispensing of fuel when a sealing relationship is not properly established.
Nozzle 14 has an indicator means 44 to indicate one or more events. Indicator means 44 is operatively connected to signal receiver 34. Based on a signal representing an event transmitted from processor assembly 30, signal receiver 34 activates indicator means 44. One example of an event would be when a sealing relationship has been established between coupling element 16 and 18. Indicator means 44 can be light emitting diodes (LED) with labels placed or etched in close relation to each LED to describe what each LED represents. If a proper sealing relationship has been established between coupling elements 16 and 18, leak check assembly 36 provides a signal to processor assembly 30 and processor assembly 30 sends a signal to signal receiver 34 to activate the LED that corresponds to a proper sealing relationship between coupling elements 16 and 18. Therefore, the operator will know that a proper sealing relationship has been established between coupling element 16 and 18 before attempting to dispense fuel into vehicle 22. Other events include when the fuel begins and continues flowing into vehicle 22, as well as, when the fuel dispensing is completed. Other events can be utilized as well. Also, indicator means 44 can be graphical display (not shown) indicating that an event has occurred and/or an audible indicator can be utilized to notify the operator that a particular event is occurring. Fuel dispenser system 10, in another embodiment thereof, includes a vacuum device 38 disposed within fuel dispenser 11, for creating a vacuum within vapor recovery conduit 26, thereby facilitating the recovery of fuel vapors from vehicle 22. Additionally, metering device 40 monitors the volumetric flow rate of the vapor and the fuel through vapor recovery conduit 26 and fuel delivery conduit 24, and metering device 40 sends a monitoring signal to processor assembly 30. Processor assembly 30, using signals received from metering device 40, determines the optimal proportional volumetric flow rates between fuel delivery and vapor recovery, and responsively controls the dispensing rate of fuel through fuel delivery conduit 24 and the recovery rate of the fuel vapor through vapor recovery conduit 26. Metering device 40 also monitors the fueling of vehicle 22 to ensure that an overfill does not occur. During operation, one embodiment of the invention performs substantially as follows. Upon arrival at fuel dispensing system 10, an operator retrieves hose 12 from its retracted position on fuel dispenser 11 and inserts nozzle 14, which has been equipped with nozzle coupling element 16, into fuel inlet port 20. Fuel inlet port 20 is either already fitted with fuel tank coupling element 18, or a coupling element can be purchased or provided. In another embodiment of the invention, nozzle coupling element 16 is secured to nozzle 14, and fuel tank coupling element 18 is removably attached to fuel inlet port 20. Fuel tank coupling element 18 is preferably designed such that an operator leaves the fuel tank coupling element 18 attached to his vehicle 22, for establishing sealing relationships with subsequent fuel dispensing systems . Upon insertion of nozzle 14 into fuel inlet port 20, an operator establishes a sealing relationship between coupling elements 16, 18. Data storage device 28, in conjunction with communicating element 32, subsequently sends signals to signal receiver 34 and processor assembly 30 regarding operator and vehicle information, such as credit card payment information, vehicle identification number, and the fuel grade selection. An operator is then prompted to confirm the data received by processor assembly 30 via input device 42. Software in fuel dispenser 11 is utilized to determine the proper speed of fuel dispensed and vapor removed during a fueling transaction based on the fuel tank size for vehicle 22 which is gathered from data storage device 28.
Also, additional fueling options other than selecting a preset amount of fuel, preset amount of gallons of fuel or to completely fill the fuel tank can be utilized as well. The operator of vehicle 22 does not need to preset or select any fueling options and can activate fuel dispenser 11 and manually dispense as much fuel as the operator desires. Thereafter, processor assembly 30 initiates a payment authorization process. While all of the above-mentioned communication and authorization processes are conducted, leak check assembly 36 conducts a test to determine whether a sealing relationship has been established between nozzle coupling element 16 and fuel tank coupling element 18. Once a proper sealing relationship is established, indicator means 44 is activated so that the operator knows that a proper sealing relationship has been established. Simultaneously, this test can determine whether any leaks are present in hose 12, and whether fuel tank coupling element 18 is properly attached to fuel inlet port 20. Once credit card authorization is granted and leak check assembly 36 confirms a sealing relationship, an operator is permitted to begin the fuel dispensing process. Once this process has begun, fuel begins to be dispensed through fuel conduit 24 while vapors housed in vehicle 22 are recovered through vapor recovery conduit 26. Indicator means 44 is activated so that the operator of vehicle 22 knows that fuel is being dispensed into vehicle 22.
Additionally, a metering device 40 is operatively connected to fuel delivery conduit 24 and vapor recovery conduit 26 for monitoring and controlling the volumetric flow rates of the respective fuel and vapor flows. In the preferred embodiment of the invention, an optimal ratio between the two volumetric flow rates is established, thereby providing the most efficient fueling of vehicle 22. In another embodiment of the present invention, a computer
(not shown) that stores and controls the settings for vehicle 22 can be connected to communicating element 32. During fueling of vehicle 22, signal receiver 34 can access the computer controlling the settings for vehicle 22 and compare them with standard settings stored in the computer for a vehicle of that same make and year. This comparison can be performed by the same software in fuel dispenser 11 that is utilized to determine the proper speed of fuel dispensed and vapor removed during a fueling transaction. Based on the comparison between the computer control settings of vehicle 22 and the standard settings for an automobile such as vehicle 22, the software will determine if any of the settings are different than the standard settings. If the settings are different, the software will notify the operator of vehicle 22 by sending the information to the display (not shown) on fuel dispenser 11 or sending the information to a receipt printer (not shown) so that the information is included with the customer's receipt. This embodiment allows for concurrent fueling, as well as, diagnostic testing of vehicle 22.
According to the invention, in another embodiment thereof, a method of providing fuel to and removing vapors from a vehicle carrying refueling information comprises the steps of communicating the refueling information held in a data storage device utilizing a communicating element to a signal receiver and/or a processor assembly. The second step is processing the refueling information with a processor assembly. The third step is removably and sealingly engaging a vapor recovery conduit and a fuel delivery conduit to a fuel inlet port utilizing a nozzle coupling element and a fuel tank coupling element. The coupling elements are formed to establish a sealing and mating relationship with each other. The fourth step is detecting for leaks in the fluid delivery conduit and a vapor recovery conduit utilizing a metering device. The fifth step is providing fuel through the fuel delivery conduit and the final step is providing a vapor vacuum through the vapor recovery conduit . While this invention has been described as having a preferred design, the present invention can be further modified within the spirit and scope of this disclosure. This application is therefore intended to cover any variations, uses, or adaptations of the invention using its general principles. Further, this application is intended to cover such departures from the present disclosure as come within known or customary practice in the art to which this invention pertains and which fall within the limits of the appended claims .
