1. A method to synchronize vehicle operation information comprising:

  • receiving the vehicle operation information via output signals generated by a plurality of sensors, wherein the plurality of sensors is coupled with a vehicle, wherein the plurality of sensors includes a first sensor that generates a first output signal conveying a first operating parameter and a second sensor that generates a second output signal conveying a second operating parameter, wherein the first output signal is associated with first timing information, and wherein the second output signal is associated with second timing information;

    detecting a first vehicle event based on the first output signal and the second output signal, the first vehicle event having a start time and an end time; and

    responsive to detecting the first vehicle event, associating information from the first output signal and the second output signal generated during the first vehicle event to create a first event record, wherein the first timing information includes a first time-stamp that indicates the start time of the first vehicle event, wherein the second timing information includes a second time-stamp that indicates the start time of the first vehicle event, and wherein the first time-stamp does not coincide with the second time-stamp; and

    synchronizing the information from the first output signal and the second output signal generated during the first vehicle event based on analysis of the first time-stamp and the second time-stamp, wherein synchronizing includes identifying and correlating corresponding information associated with one or more physical phenomena in the first output signal and the second output signal during the first vehicle event.
