Abstract

A control system for a vehicle is provided. The system generally includes a first setup module that configures at least one data recording trigger based on data parameters received from at least one of a telematics system and a technician tool. A data logger module records and stores real-time vehicle data based on the at least one data recording trigger.

Claims

1. A control system for a vehicle, comprising:

a first setup module that configures at least one data recording trigger based on data parameters received from at least one of a telematics system and a technician tool; and

a data logger module that records and stores real-time vehicle data based on the at least one data recording trigger.

2. The system of claim 1 further comprising a second setup module that configures overwrite parameters that correspond to the at least one data recording trigger and wherein the data logger module overwrites the stored real-time vehicle data based on newly recorded real-time vehicle data and the overwrite parameters.

3. The system of claim 2 wherein the second setup module configures the overwrite parameters based on input parameters received from at least one of a telematics system and a technician tool.

4. The system of claim 1 further comprising a data retrieval module that retrieves the stored real-time vehicle data based on a data request received from at least one of a telematics system and a technician tool.

5. The system of claim 4 wherein the data retrieval module transmits the retrieved real-time vehicle data to the at least one of the telematics system and the technician tool.

6. The system of claim 1 wherein the data recording trigger is defined by at least one of a diagnostic trouble code, a variable address, an address type, an operator, and an operand.

7. The system of claim 1 wherein the data logger module records the real-time vehicle data based on activation of a diagnostic trouble code.

8. The system of claim 1 wherein the data logger module records the real-time vehicle data in a circular buffer until a condition defined by the data recording trigger is met.

9. The system of claim 8 wherein the data logger module records the real-time vehicle data in the circular buffer until a trigger position is met.

10. The system of claim 8 further comprising a datastore that maintains the real-time vehicle data when power is removed from the control system and wherein the data logger module stores the recorded real-time vehicle data in the datastore.

11. A method of recording real-time vehicle data, comprising:

receiving data parameters from at least one of a telematics system and a technician tool;

configuring at least one data recording trigger based on the data parameters; and

recording and storing real-time vehicle data based on the at least one data recording trigger.

12. The method of claim 11 further comprising:

configuring overwrite parameters that correspond to the at least one data recording trigger; and

overwriting the stored real-time vehicle data based on newly recorded real-time vehicle data and the overwrite parameters.

13. The method of claim 12 wherein the configuring the overwrite parameters is based on input parameters received from at least one of a telematics system and a technician tool.

14. The method of claim 11 further comprising retrieving the stored real-time vehicle data based on a data request received from at least one of a telematics system and a technician tool.

15. The method of claim 14 further comprising transmitting the retrieved real-time vehicle data to the at least one of the telematics system and the technician tool.

16. The method of claim 11 further comprising defining the data parameter to be at least one of a diagnostic trouble code, a variable address, an address type, an operator, and an operand.

17. The method of claim 11 wherein the recording the real-time vehicle data is based on activation of a diagnostic trouble code.

18. The method of claim 11 wherein the recording the real-time vehicle data comprises recording the real-time vehicle data in a circular buffer until a condition defined by the data recording trigger is met.

19. The method of claim 18 wherein the recording the real-time vehicle data comprises recording the real-time vehicle data in, the circular buffer until a trigger position is met.

20. The method of claim 18 further comprising maintaining the real-time vehicle data in memory when power is removed from the control system.
