Abstract

An event data recorder (EDR) system includes an event identification module, a parameter selection module, and an event recorder module. The event identification module identifies occurrences of a first event and second event of M predetermined events based on operating conditions of an automotive vehicle. The parameter selection module selects a first set of parameters to record from N predetermined parameters when the first event occurs. The parameter selection module selects a second set of parameters to record from the N predetermined parameters when the second event occurs. The event recorder module records data corresponding to the first set of parameters when the first event occurs and records data corresponding to the second set of parameters when the second event occurs. M and N are integers greater than 1 and the first set includes at least one parameter that is different from the parameters included in the second set.

Claims

1. An event data recorder (EDR) system, comprising:

an event identification module that identifies occurrences of a first event and second event of M predetermined events based on operating conditions of an automotive vehicle;

a parameter selection module that selects a first set of parameters to record from N predetermined parameters when the first event occurs and that selects a second set of parameters to record from the N predetermined parameters when the second event occurs; and

an event recorder module that records data corresponding to the first set of parameters when the first event occurs and that records data corresponding to the second set of parameters when the second event occurs, wherein M and N are integers greater than 1 and the first set includes at least one parameter that is different from the parameters included in the second set.

2. The EDR system of claim 1, wherein the event recorder module records a single value for each parameter included in the first and second sets.

3. The EDR system of claim 1, wherein the event recorder module records data corresponding to the first and second sets of parameters for a predetermined period.

4. The EDR system of claim 1, further comprising an event order module that determines a chronological order of each of the M predetermined events that occur.

5. The EDR system of claim 1, further comprising an event selection module that selects the M predetermined events to be identified from Q predetermined events, wherein Q is an integer greater than M.

6. The EDR system of claim 5, wherein the event selection module and the parameter selection module receive instructions from one of a handheld tool and a satellite communication network, and respectively select from the Q predetermined events and the N predetermined parameters based on the instructions.

7. The EDR system of claim 5, further comprising an event counter module that determines a number of occurrences for each of the Q predetermined events.

8. An event data recorder (EDR) system, comprising:

a first EDR module that selectively records data associated with a first system of a vehicle; and

an EDR activation device installed on the vehicle that activates the first EDR module to record the first system data based on a driver input.

9. The EDR system of claim 8, further comprising a second EDR module that selectively records data associated with a second system of the vehicle, wherein the first EDR module selectively activates the second EDR module to record the second system data.

10. The EDR system of claim 9, wherein the first EDR module activates the second EDR module when the EDR activation device activates the first EDR module.

11. An method for recording event data, comprising:

identifying occurrences of a first event and second event of M predetermined events based on operating conditions of an automotive vehicle;

selecting a first set of parameters to record from N predetermined parameters when the first event occurs;

selecting a second set of parameters to record from the N predetermined parameters when the second event occurs;

recording data corresponding to the first set of parameters when the first event occurs; and

recording data corresponding to the second set of parameters when the second event occurs, wherein M and N are integers greater than 1 and the first set includes at least one parameter that is different from the parameters included in the second set.

12. The method of claim 11, further comprising recording a single value for each parameter included in the first and second sets.

13. The method of claim 11, further comprising recording data corresponding to the first and second sets of parameters for a predetermined period.

14. The method of claim 11, further comprising determining a chronological order of each of the M predetermined events that occur.

15. The method of claim 11, further comprising selecting the M predetermined events to be identified from Q predetermined events, wherein Q is an integer greater than M.

16. The method of claim 15, further comprising receiving instructions from one of a handheld tool and a satellite communication network, and selecting from the Q predetermined events and the N predetermined parameters based on the instructions.

17. The method of claim 15, further comprising determining a number of occurrences for each of the Q predetermined events.

18. The method of claim 11, further comprising:

selectively recording data associated with a first system of the vehicle; and

activating a first event data recorder (EDR) module to record the first system data based on a driver input.

19. The method of claim 18, further comprising selectively recording data associated with a second system of the vehicle, wherein the first EDR module selectively activates a second EDR module to record the second system data.

20. The method of claim 19, further comprising activating the second EDR module when the first EDR module is activated.
