Abstract

A system includes a simulator device having a computing device having a computer processor and a computer readable medium. The simulator device further includes a communication port configured for communicating with an emissions inspection tool. The simulator device also has a database associated with the computing device and including multiple vehicle profiles, wherein individual ones of the multiple vehicle profiles include a plurality of Engine Control Units (ECUs), and wherein individual ones of the plurality of ECUs are configured to simulate a plurality of Parameter IDs (PIDs) and corresponding response codes. The individual ones of the multiple vehicle profiles are independently selectable for providing at least one PID response code to the vehicle inspection tool. The computing device is configured to perform a vehicle simulation for auditing a vehicle inspection tool.

Claims

1. A vehicle simulation system comprising:

a simulator device including a computing device having a computer processor and a computer readable medium, the simulator device further including a communication port configured for communicating with an emissions inspection tool;

a database associated with the computing device and including multiple vehicle profiles, wherein each of the multiple vehicle profiles include a plurality of Electronic Control Units (ECUs), and wherein each of the plurality of ECUs are configured to simulate a plurality of Parameter IDs (PIDs) and corresponding response codes; and

wherein each of the multiple vehicle profiles are independently selectable for providing at least one PID response code to the emissions inspection tool;

wherein the computing device is configured to perform a vehicle simulation for auditing the emissions inspection tool.

2. The system of claim 1 further comprising a vehicle port configured for communicating with a vehicle diagnostics port.

3. The system of claim 2, wherein the system is configured to query and monitor a vehicle via the vehicle diagnostics port and further configured to create and store a new vehicle profile corresponding to the monitored vehicle.

4. The system of claim 1, wherein the system is configured to simulate a plurality of ECUs simultaneously.

5. The system of claim 1, wherein the system is configured to simulate a plurality of PIDs at an adjustable interval.

6. The system of claim 5, wherein the adjustable interval comprises a simultaneous simulation.

7. The system of claim 5, wherein the adjustable interval comprises a sequential simulation.

8. The system of claim 5, wherein the adjustable interval corresponds to a predetermined “

within specification”

interval.

9. The system of claim 5, wherein the adjustable interval corresponds to a predetermined “

outside of specification”

interval.

10. The system of claim 5, wherein the adjustable interval of individual ones of the plurality of PIDs are independently adjustable.

11. The system of claim 5, wherein the adjustable interval is adjustable via a knob for easily adjusting the delay of at least one PID response code.

12. The system of claim 1, wherein at least one vehicle profile includes a PID that does not exist in a vehicle corresponding to the at least one vehicle profile.

13. The system of claim 1, wherein at least vehicle profile includes a PID that is not automatically detectable in a vehicle corresponding to the at least one vehicle profile.

14. The system of claim 1, wherein a first ECU is configured to respond with a valid PID response code and a second ECU is configured to respond with an invalid PID response code.

15. The system of claim 1, wherein the system is configured to provide a display signal.

16. The system of claim 15, wherein the display signal includes a first display corresponding to a first ECU and a second display corresponding to a second ECU.

17. The system of claim 15, wherein the display signal includes a display of the vehicle corresponding to the vehicle profile, the ECU being simulated, and an icon corresponding to the PID response being simulated.

18. The system of claim 1, wherein at least one of the multiple vehicle profiles stored in the database is adjustable.

19. The system of claim 1, wherein individual ones of the plurality of PIDs are corresponding response codes are randomly determined.

20. The system of claim 1, wherein individual ones of the plurality of PIDs are corresponding response codes are cyclically determined.

21. The system of claim 1, wherein individual ones of the plurality of PIDs are corresponding response codes are statically predetermined.

22. The system of claim 1, wherein individual ones of the plurality of PIDs are independently suppressible.

23. The system of claim 1, further comprising one or more diagnostic trouble codes (DTCs) stored within the database.

24. The system of claim 23, wherein at least one of the DTCs is configured to be applied to the simulation.
