In at least some embodiments, the fuel authorization controller at the vehicle automatically uses the fuel tank sensor data and known tank size to include in a fuel authorization request sent to a fuel vendor data defining how much fuel is required to fill the vehicle fuel tanks. In at least some embodiments, the fuel vendor consults data from a source other than the vehicle (such as records maintained by the fuel authorization program) to determine how large the vehicles fuel tanks are, and to calculate how much fuel is required. ## Claims ### Claim 1 A method for administering a fuel authorization program, the method comprising the steps of: (a) in response to receiving a radiofrequency (RF) query from a participating fuel vendor over an RF data link at an enrolled vehicle, automatically implementing the steps of: (i) obtaining a fuel tank reading from a fuel tank sensor at the vehicle to provide an indication of how much fuel is required to fill a vehicle fuel tank; (ii) dynamically retrieving fuel authorization credentials from at least one of a vehicle data bus and a non-removable, non-transitory vehicle memory at the vehicle, thereby reducing a likelihood that the vehicle fuel authorization credentials are being used with an non-enrolled vehicle; (iii) communicating the indication of how much fuel is required and vehicle fuel authorization credentials from the vehicle to the fuel vendor, using at least one of the RF data link and the IR data link; (b) automatically using the vehicle fuel authorization credentials to determine if the vehicle is authorized to receive fuel; (c) after determining the vehicle is enrolled in the fuel authorization program and is authorized to receive fuel, enabling fuel delivery at the fuel pump the vehicle is proximate to in a quantity sufficient to fill the fuel tank based on the indication of how much fuel is required communicated from the vehicle to the fuel vendor. ### Claim 2 (depends on 1) The method of claim 1, further comprising the step of automatically establishing an infrared (IR) data link between the vehicle and a specific fuel pump, thereby unambiguously identifying the fuel pump the vehicle is proximate to. ### Claim 3 (depends on 1) The method of claim 1, wherein the data retrieved from the at least one of the vehicle data bus and the non-removable, non-transitory vehicle memory comprises a VIN. ### Claim 4 (depends on 1) The method of claim 1, further comprising the step of automatically periodically reporting fuel tank readings from the fuel tank sensor at the vehicle during operation of the vehicle to a remote computing device, using at least one of a cellular data link and a satellite data link. ### Claim 5 (depends on 4) The method of claim 4, further comprising the step of automatically applying a calibration factor to the fuel tank sensor at the vehicle based on instructions received from the remote computing device. ### Claim 6 (depends on 1) The method of claim 1, further comprising the steps of: (a) remote from the vehicle, automatically comparing fuel tank readings and authorized fuel quantities over multiple fuel authorizations to determine a calibration factor to apply to readings taken by the fuel tank sensor; (b) automatically sending the calibration factor to from the fuel vendor to the vehicle in subsequent fuel transactions; and (c) automatically applying the calibration factor at the vehicle for any subsequent fuel tank readings. ### Claim 7 (depends on 1) The method of claim 1, wherein after a fuel transaction is complete, automatically implementing the steps of: (a) obtaining a fuel tank reading from the fuel tank sensor at the vehicle, and if the fuel tank reading is not full, then: (b) applying a calibration factor to the fuel tank sensor at the vehicle. ### Claim 8 (depends on 1) The method of claim 1, wherein if less fuel than indicated by the communication from the vehicle to the fuel vendor is delivered because the fuel pump automatically shut off to prevent spilling, automatically implementing the steps of: (a) sending a communication from the fuel vendor to the vehicle over the RF data link indicating that less fuel was required to fill the tank than indicated by the communication from the vehicle to the fuel vendor; and (b) applying a calibration factor to the fuel tank sensor at the vehicle. ### Claim 9 (depends on 1) A non-transitory memory medium having machine instructions stored thereon for facilitating a fuel transaction with a vehicle, the machine instructions, when implemented by a processor, carrying out the functions of step (a) of claim 1. ### Claim 10 (depends on 4, 9) The non-transitory memory medium of claim 9, further having machine instructions stored thereon for implementing the step of claim 4. ### Claim 11 (depends on 5, 9) The non-transitory memory medium of claim 9, further having machine instructions stored thereon for implementing the step of claim 5. ### Claim 12 (depends on 6, 9) The non-transitory memory medium of claim 9, further having machine instructions stored thereon for implementing step (c) of claim 6. ### Claim 13 (depends on 7, 9) The non-transitory memory medium of claim 9, further having machine instructions stored thereon for implementing the steps of claim 7. ### Claim 14 (depends on 8, 9) The non-transitory memory medium of claim 9, further having machine instructions stored thereon for implementing step (b) of claim 8. ### Claim 15 (depends on 1) A non-transitory memory medium having machine instructions stored thereon for facilitating a fuel transaction with a vehicle, the machine instructions, when implemented by a processor, carrying out the functions of steps (b), (c), and (d) of claim 1. ### Claim 16 (depends on 6, 15) The non-transitory memory medium of claim 15, further having machine instructions stored thereon for implementing step (b) of claim 6. ### Claim 17 (depends on 8, 15) The non-transitory memory medium of claim 15, further having machine instructions stored thereon for implementing step (a) of claim 8.
