Abstract

System and method for modifying the operation of an engine comprising an engine control unit coupled to the engine, a command module coupled to the engine control unit, wherein the command module is operable to modify operating characteristics of the engine by reconfiguring the function of the engine control unit. The engine control unit further comprises software and/or firmware, and the command module reconfigures the function of the engine control unit by altering the software and/or firmware. The command module may modify the engine operation, for example, based upon environmental conditions, topographic conditions, and/or traffic conditions.

Claims

1. A system for modifying the operation of an engine, comprising:

an engine control unit coupled to the engine;

a geolocation device;

a command module coupled to the engine control unit; and

one or more accelerometers coupled to the command module;

wherein the command module is operable to modify operating characteristics of the engine using the engine control unit based upon a location of the vehicle determined using the geolocation device;

wherein the command module reconfigures the function of the engine control unit based upon data from the one or more accelerometers.

9. The system of claim 1, wherein the engine control unit further comprises software;

and wherein the command module reconfigures the function of the engine control unit by altering the software.

10. The system of claim 1, wherein the engine control unit further comprises firmware;

and wherein the command module reconfigures the function of the engine control unit by altering the firmware.

11. The system of claim 1, wherein the command module modifies the engine operation based upon environmental conditions.

12. The system of claim 1, wherein the command module modifies the engine operation based upon topographic conditions.

13. The system of claim 1, wherein the command module modifies the engine operation based upon traffic conditions.

14. The system of claim 1, wherein the engine operation is modified to maximize fuel economy.

15. The system of claim 1, further comprising:

a remote base station in communication with the command module; and

wherein the command module is adapted to receive engine configuration commands transmitted from the remote base station.

16. The system of claim 1, further comprising:

an on-board diagnostic system for the engine coupled to the command module.

17. The system of claim 16, wherein the command module receives vehicle performance data from the on-board diagnostic system;

and

wherein the command module reconfigures the function of the engine control unit based upon data from the on-board diagnostic system.

18. The system of claim 16, wherein the command module reconfigures the function of the engine control unit via the on-board diagnostic system or other conduit to an engine control module.

2. A system for modifying the operation of an engine, comprising:

an engine control unit coupled to the engine;

a geolocation device;

a command module coupled to the engine control unit; and

wherein the command module is operable to modify operating characteristics of the engine using the engine control unit based upon a location of the vehicle determined using the geolocation device;

wherein the function of the engine control unit is adapted to be reconfigured by a tuning chip that replaces an existing erasable programmable, read-only memory (EPROM) chip.

3. A method for controlling the operation of an engine, comprising:

determining a location of a vehicle;

receiving an engine operation command at a command module in a the vehicle, the engine operation command based on the determined location of the vehicle, and

reconfiguring an engine control device of the vehicle in response to the engine operation command;

wherein the engine control device is adapted to be reconfigured by a tuning chip that replaces an existing erasable programmable, read-only memory (EPROM) chip.

4. A method for controlling the operation of an engine, comprising:

receiving, at a command module, vehicle operation data from a vehicle monitoring system in a vehicle, the vehicle monitoring system including two or more accelerometers; and

reconfiguring an engine control device in response to the vehicle operation data, the vehicle operation data including data from one or more accelerometers.

5. The method of claim 4, wherein the engine operation is modified to maximize fuel economy.

6. The method of claim 4, further comprising:

reconfiguring a function of the engine control device based upon data from an on-board diagnostic system for the vehicle.

7. The method of claim 6, wherein the command module reconfigures the function of the engine control device via the on-board diagnostic system.

8. A system for modifying the operation of an engine, comprising:

an engine control unit coupled to the engine;

a geolocation device;

a command module coupled to the engine control unit; and

wherein the command module is operable to modify operating characteristics of the engine using the engine control unit based upon a location of the vehicle determined using the geolocation device.

19. A method for controlling the operation of an engine, comprising:

determining a location of a vehicle;

receiving an engine operation command at a command module in a the vehicle, the engine operation command based on the determined location of the vehicle; and

reconfiguring an engine control device of the vehicle in response to the engine operation command.

20. The method of claim 19, wherein the command module receives the engine operation command via a wireless link to a base station.

21. The method of claim 19, further comprising:

reconfiguring a function of the engine control device by altering software in the engine control device.

22. The method of claim 19, further comprising:

reconfiguring a function of the engine control device by altering firmware in the engine control device.

23. The method of claim 19, wherein the reconfiguring modifies an engine operation based upon environmental conditions.

24. The method of claim 19, wherein the reconfiguring modifies an engine operation based upon topographic conditions.

25. The method of claim 19, wherein the reconfiguring modifies an engine operation based upon traffic conditions.

26. The method of claim 19, wherein the command module is coupled to the engine control device via an on-board diagnostic system for the vehicle.

27. The method of claim 26, wherein the command module reconfigures a function of the engine control device via the on-board diagnostic system.
