Abstract

An apparatus and method is provided that allows a host workstation to communicate with all types of VDR available to a user to record events in a vehicle type selected by the user. The host workstation can also alert the user when the incorrect VDR is connected based upon the vehicle selection by the user. Once connected, the host workstation can configure the VDR for the desired recording parameters.

Claims

1. A software recorded on a computer readable medium capable of causing a host workstation to perform steps comprising of:

selecting a type of vehicle by a user that a user wants to record an event;

instructing the user the type of vehicle data recorder with proper communication protocols to connect to the host workstation and to an electronic control unit based on the selected vehicle;

detecting if the vehicle data recorder is attached to the host workstation;

querying the vehicle data recorder with a tool identification command to identify if the correct type of vehicle data recorder is attached to the host workstation; and

configuring the vehicle data recorder to record a desired event.

2. The software of claim 1, wherein detecting if the vehicle data recorder is attached can be done manually by user input or automatically through communication between the host workstation and the vehicle data recorder.

3. The software of claim 1, further comprising the step of:

sending a tool connection error signal to the host workstation when the vehicle data recorder is not properly connected to the host workstation.

4. The software of claim 1, further comprising the step of:

sending vehicle data recorder type error signal to the host workstation when the software detects that the incorrect type of vehicle data recorder is attached based on the vehicle selection.

5. The software of claim 1, wherein configuring the vehicle data recorder includes configuring to at least one of recording data for a predetermined period of time, recording data when a trigger button is actuated by the user, recording data for a period of time before and after the trigger is actuated by the user, any other time period and a combination thereof.

6. The software of claim 1, wherein at the querying step, the software can communicate with any type of vehicle data recorder that can communicate with any communication protocol communicated by the electronic control unit on a vehicle.

7. The software of claim 1, wherein the host workstation is a computing device.

8. The software of claim 7, wherein the computing device can be one of a personal computer, a personal digital assistant and a scan tool or any device that is capable of communicating with the vehicle data recorder.

9. The software of claim 4, further comprising the step of:

sending vehicle data recorder type error signal to the host workstation further includes informing the user the correct type of vehicle data recorder to attach to the host workstation.

10. A method of communicating with a vehicle data recorder, comprising:

selecting the desired vehicle type by a user that the user wants to record an event;

instructing the user the vehicle data recorder type equipped with proper communication protocols to connect to a host workstation and to an electronic control unit based on the selected vehicle type;

detecting a connection between the vehicle data recorder and the host workstation;

querying the vehicle data recorder with tool identification command to identify the type of vehicle data recorder attached to the host workstation; and

configuring the vehicle data recorder to record a desired event.

11. The method of communicating of claim 10, wherein detecting a connection can be done manually by user input or automatically through communication between the host workstation and the vehicle data recorder.

12. The method of communicating of claim 10, further comprising the step of:

sending a tool connection error signal to the host workstation when the vehicle data recorder is not properly connected to the host workstation.

13. The method of communicating of claim 10, wherein configuring the vehicle data recorder includes configuring to at least one of recording data for a predetermined period of time, recording data when a trigger button is actuated by a user, recording data for a period of time before and after the trigger is actuated by the user, any other time period and a combination thereof.

14. The method of communicating of claim 10, wherein at the querying step, the software can communicate with any type of vehicle data recorder that can communicate with any communication protocol communicated by the electronic control unit on a vehicle.

15. The method of communicating of claim 10, wherein the host workstation is a computing device.

16. The method of communicating of claim 15, wherein the computing device can be one of a personal computer, a personal digital assistant and a scan tool or any device that is capable of communicating with the vehicle data recorder.

17. A host workstation, comprising:

an input device to input information from a user;

an output device to communicate information;

a communication port to communicate with an external device;

a memory to store information;

a storage device to store information; and

a processor in communication with the storage, input and output devices, the communication port and the memory, wherein the host workstation is capable of performing functions comprising of;

selecting the desired vehicle type that the user wants to record an event;

instructing the user the vehicle data recorder type equipped with proper communication protocols to connect to the host workstation based on the selected vehicle type;

detecting for a connection between the vehicle data recorder and the host workstation;

querying the vehicle data recorder with tool identification command to identify the type of vehicle data recorder attached to the host workstation; and

configuring the vehicle data recorder to record a desired event.

18. The host workstation of claim 17, wherein detecting for a connection can be done manually by user input or automatically through communication between the host workstation and the vehicle data recorder.

19. The host workstation of claim 17, further comprising the step of:

sending a tool connection error signal to the host workstation when the vehicle data recorder is not properly connected to the host workstation.

20. The host workstation of claim 17, wherein configuring the vehicle data recorder includes configuring to at least one of recording data for a predetermined period of time, recording data when a trigger button is actuated by a user, recording data for a period of time before and after the trigger is actuated by the user, any other time period and a combination thereof.

21. The host workstation of claim 17, wherein at the querying step, the software can communicate with any type of vehicle data recorder that can communicate with any communication protocol communicated by the electronic control unit on a vehicle.

22. The host workstation of claim 17, wherein the host workstation is a computing device.

23. The host workstation of claim 22, wherein the computing device can be one of a personal computer, a personal digital assistant and a scan tool or any device that is capable of communicating with the vehicle data recorder.

24. A method of communicating with a vehicle data recorder, comprising:

selecting the desired vehicle type by a user that the user wants to record an event;

instructing the user the vehicle data recorder type equipped to connect to a host workstation based on the selected vehicle type;

automatically detecting a connection between the vehicle data recorder and the host workstation;

automatically querying the vehicle data recorder with tool identification command to identify the type of vehicle data recorder attached to the host workstation;

automatically selecting the software module that communicates with the vehicle data recorder; and

automatically configuring the vehicle data recorder to record a desired event.

25. The method of communicating of claim 24, further comprising selecting the recording parameter based on user preference.
