Abstract

A system for control of automatic refueling of automotive vehicles parked alongside a fuel dispenser unit which allows for a customer to control a refueling procedure without having to exit the vehicle. The control system includes a processing unit, control operating units, operating units and a communications system which is located within the vehicle to be refueled. The communications system has the capability to start, monitor and finish the refueling procedure by transmitting and receiving data signals which concern the refueling procedure such as signals which start the refueling procedure and signals which interrupt the procedure. The data signals are received by the from the vehicle into the processing unit where the signals are processed. The processed data signals are directed to control operating units. The control operating units then direct operating units in carrying out operating functions which are necessary to automatically refuel the vehicle.

Claims

1. A system for control of automatic refueling of automotive vehicles parked alongside a fuel dispenser unit, the system comprising:

(a) a communication means for starting, monitoring and finishing a refueling procedure, said refuelling procedure including a starting step, a fuel supply step and a finishing step, the communications means being arranged within a vehicle to be refueled such that during the refuelling procedure the communications means is functional to control the refuelling procedure, the communications means also being functional to stop the fuel supply step by transmitting from the vehicle an interruption data signal;

(b) operating control units for controlling operating functions involved within said refuelling procedure, the operating functions being carried out by respective operating units having the capability of performing the operating functions on vehicle fuel systems which have different refuelling configurations;

(c) a processing unit for processing data signals from the vehicle and directing the processed data signals to and from said operating control units which control said respective operating units in executing the refuelling procedure;

(d) wherein the data signals comprise first and second data signals, said first data signals comprising fill pipe data, fuel cap position data, fuel type data and cap lock data, and said second data signals comprising customer identification data and customer bank account data; and

(e) wherein the starting step includes processing the first and second data signals to determine whether the operating units are compatible with the vehicle'"'"'s fill pipe, fuel cap position, fuel type and cap lock such that the operating units can refuel the vehicle and whether automatic payment can be made for the fuel, should the starting step determine that the operating units are capable of refuelling the vehicle and payment can automatically be made, the starting step approves the starting of the fuel supply step, otherwise the starting step aborts the refuelling procedure;

(f) wherein the communication means includes a transmitter/receiver means for transmitting and receiving signals, the transmitter/receiver means being located on the fuel dispenser unit and also being arranged within a rear light unit of the vehicle and wherein said fill pipe data signals, said fuel cap position data signals, said fuel type data signals, and said cap lock data signals are transmitted by the transmitter/receiver means on the vehicle and received by the transmitter/receiver means on the fuel dispenser unit.

2. The system as claimed in claim 1, wherein said communication means is operated continuously.

3. The system as claimed in claim 2, wherein said continuously operated communication means includes a vehicle control means for starting and finishing the refueling procedure by using at least one operating device which is engaged for starting the procedure and then respectively released for finishing the procedure.

4. The system as claimed in claim 3, wherein said vehicle control means comprise at least one pedal, operated for starting, respectively finishing, said refuelling procedure by pressing, respectively releasing, said pedal.

5. The system as claimed in claim 4, wherein a combination of pedals is used.

6. The system as claimed in claim 2, wherein said continuously operated communication means includes an in-car terminal having at least one key which is operated for starting, respectively finishing, said refuelling procedure by pressing, respectively releasing said key.

7. The system as claimed in claim 6, wherein a combination of pedals and keys is used.

8. The system as claimed in claim 6, wherein said transmitter/receiver means comprise electromagnetic wave transmitter/receiver means for receiving and transmitting electromagnetic waves.

9. The system as claimed in claim 8, wherein said transmitter/receiver means is functional to transmit and receive infra-red light waves.

10. The system as claimed in claim 9, wherein said transmitter/receiver means includes light emitting diodes for transmitters and semi-conductor infra-red receivers.

11. The system as claimed in claim 1, wherein said transmitter/receiver means comprise acoustic wave transmitter/receiver means for receiving and transmitting acoustic waves.

12. The system as claimed in claim 1, wherein said communication means comprise electronic circuitry holding said data signals to be communicated.

13. The system as claimed in claim 1, wherein the transmitter/receiver means for transmitting and receiving signals is an infra-red electromagnetic transmitter/receiver means for transmitting and receiving infra-red light waves where the signals are conducted to the processing unit in order to determine respectively, the fill pipe position relative to the fuel cap, the fuel cap position relative to the rear light unit, the type of fuel to be refuelled, and the lock of the cap to be opened and locked respectively before and after the refuelling procedure, subsequently generating fill pipe position data, fuel cap position data, cap lock control data, and fuel type control data, and wherein said second data signals are processed in the processing unit in order to generate customer identification control data and customer bank account control data, the corresponding data signals being sent to a memory unit of said processing unit to be stored.

14. The system as claimed in claim 13, wherein at least said second data signals are displayed on an in-car terminal which further enables identification confirmation and fuel supply interrogation, interruption, continuation and finishing.

15. The system as claimed in claim 13, wherein during the starting step subsequently the fuel cap position data, the cap lock control data, the fill pipe position data, the fuel type control data, the customer identification control data, and the customer bank account control data are read from their respective processing unit memory units, and are processed by said processing unit in order to generate, after approval, a combined data acceptance signal comprising combined refuelling procedure data.

16. The system as claimed in claim 15, wherein said combined data acceptance signal generated is directed to a robot arm control unit in order to enable a robot arm to carry out the fuel supply step.
