Abstract

A method for dispensing fuel has features to prevent theft of fuel and also control maintenance of authorized vehicles. The system includes a portable memory unit which remains with each vehicle. The portable memory unit is removably connected to an on-board computer on the vehicle. The on-board computer senses certain vehicle conditions and changes through transducers carburetor settings. The on-board computer also writes into the portable memory unit a warning if any of the vehicle conditions exceed limits. At the fuel dispensing site, a data processing unit receives the portable memory unit to read from it coded information. A central processing unit is located at a central records site and connected to the remote processing unit for record storage. The remote processing unit reads from the portable memory unit a last mileage at which fuel was dispensed, and compares it to a current mileage entered by the operator into the remote processing unit. A next service mileage is also read by the remote processing unit and compared to the current mileage. If the current mileage exceeds a next service mileage or if warnings are read by the remote processing unit, the operator is notified to immediately take the vehicle to a maintenance facility for maintenance.

Claims

1. A method of dispensing fuel and providing maintenance information for a motor vehicle, comprising:

providing with the vehicle a portable memory means for storing, retrieving and updating selected data;

providing with the vehicle an on-board processing means for sensing at least one vehicle condition, and for poviding a warning in the on-board processing means should the condition exceed selected bounds, the on-board processing means having a receptacle means for releasably receiving the memory means and storing the data and any warnings in the memory means;

inserting the memory means into the receptacle means of the on-board processing means and storing in the memory means the data and any warnings received from the on-board processing means;

providing at a fuel dispensing site a remote processing unit having receptacle means for releasably receiving the memory means, providing with the remote processing unit a means for reading and updating the data in the memory means, and providing with the remote processing unit an interface means for controlling a pump to dispense fuel;

removing the memory means from the receptacle means of the on-board processing means and inserting the memory means into the receptacle means of the remote processing unit, then reading with the remote processing unit from the memory means the data and any warnings;

notifying the vehicle operator with the remote processing unit of service needs if a warning has been entered in the memory means;

if a warning has not been entered in the memory means, turning on the pump with the remote processing unit; and

if a warning has been entered in the memory means, refusing with the remote processing unit to turn on the pump.

2. A method of dispensing fuel and providing maintenance information for a motor vehicle, comprising:

providing with the vehicle a portable memory means for storing, retrieving and updating selected data including a next service mileage;

providing with the vehicle an on-board processing means for sensing at least one vehicle condition, and for providing a warning in the on-board processing means should the condition exceed selected bounds, providing with the on-board processing means a means for sensing current mileage of the vehicle, the on-board processing means having a receptacle means for releasably receiving the memory means and storing current miles and any warnings in the memory means;

inserting the memory means into the receptacle means of the on-board processing means and storing in the memory means the current mileage and any warnings;

providing at a fuel dispensing site a remote processing unit having receptacle means for releasably receiving the memory means, providing with the remote processing unit a means for reading and updating the data in the memory means, and providing with the remote processing unit an interface means for controlling a pump to dispense fuel and for the monitoring the fuel dispensed;

removing the memory means from the receptacle means of the on-board processing means and inserting the memory means into the receptacle means of the remote processing unit, then reading with the remote processing unit from the memory means current mileage of the vehicle, an identification number, a next service mileage for the vehicle and any warnings;

verifying with the remote processing unit that the identification number is a valid number;

comparing with the remote processing unit the current mileage with the next service mileage and notifying the vehicle operator of service needs if the current mileage exceeds the next service mileage, and if any warnings have been entered in the memory means;

if the identification number is valid, turning on the pump and monitoring with the remote processing unit the amount of fuel dispensed; and

removing the memory means from the receptacle means of the remote processing unit and re-inserting the memory means into the receptacle means of the on-board processing unit.

3. The method according to claim 2 further comprising:

refusing with the remote processing unit to turn on the pump if any warnings have been entered in the memory means.

4. The method according to claim 3 wherein the on-board processing means disables the vehicle from operation unless the memory means is inserted into the receptacle means of the on-board processing unit.

5. The method according to claim 2, further comprising the steps of:

providing a central processing unit at a central records site remote from the fuel dispensing site with storage means for storing data transmitted to it by the remote processing unit; and

transmitting with the remote processing unit to the central processing unit a message that the remote processing unit has notified the operator of service needs and the warning, if any.

6. A method of dispensing fuel and providing maintenance for a motor vehicle, comprising:

providing with the vehicle a key having internal memory means for storing, retrieving and updating selected data of the vehicle;

providing with the vehicle an on-board processing means for sensing current mileage and at least one vehicle condition, and for providing a warning in the onboard processing means should the condition exceed selected bounds, the on-board processing means having a receptacle means for releasably receiving the key and storing the current mileage and any warnings in the key;

inserting the key into the receptacle means of the on-board processing means and storing in the memory means the current mileage and any warnings;

providing at a fuel dispensing site a remote processing unit having recpetacle means for releasably receiving the key and for reading, comparing and undating the data in the memory means, and providing with the remote processing unit an interface means for controlling a pump to dispense fuel and for monitorting the fuel dispensed;

removing the key from the receptacle means of the on-board processing means, and inserting the key into the remote processing unit and reading with the remote processing unit from the memory means an identification number, a current mileage, a last mileage at which fuel was dispensed, a next service mileage for the vehicle and any warnings;

verifying with the remote processing unit that the idenfitication number is a valid number;

comparing with the remote processing unit the next service mileage with the current mileage and notifying the vehicle operator of service needs if the current mileage exceeds the next service mileage, and if a warning has been entered in the memory means; and

turning on the pump with the remote processing unit if the identification number if valid and monitoring with the remote processing unit the amount of fuel dispensed.

7. The method according to claim 6, further comprising:

updating in the memory means the last mileage at which fuel was dispensed with the current mileage by using the remote processing means.
