Abstract

Systems and methods for location reporting of detected events during vehicle operation in accordance embodiments of the invention are disclosed. In one embodiment of the invention, an event reporting telematics unit configured to report the location of events includes a first sensor configured to determine sensor information, a storage device configured to store sensor information and an event reporting application, and a processor, wherein the event reporting application configures the processor to receive a first sensor information using the first sensor, calculate a first sensor information timestamp, where the first sensor information timestamp is associated with the first sensor information, determine the occurrence of a vehicle event, complete the determination of the vehicle event, correlate the first sensor information with the determined event using the first sensor information timestamp, and determine the time corresponding to the beginning of the determined event.
