1. A method to synchronize vehicle operation information comprising:

  • providing a plurality of sensors coupled with a vehicle, the sensors including a first sensor that generates a first output signal conveying information related to a first operating parameter, and a second sensor that generates a second output signal conveying information related to a second operating parameter;

    receiving the vehicle operation information via output signals generated by the plurality of sensors, 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 physical phenomena in the first output signal and the second output signal during the first vehicle event.
