The methods involve operating at least one processor to: receive a telematics data stream; define a plurality of sliding windows for the telematics data stream, each sliding window containing a portion of the telematics data stream, each sliding window overlapping with one or more neighboring sliding windows, each sliding window including: a logical window; a first buffer preceding the logical window; and a second buffer following the logical window; the logical window being adjacent with one or more neighboring logical windows of the one or more neighboring sliding windows without overlapping the one or more neighboring logical windows; identify a vehicle event based on the portion of the telematics data stream contained within one of the sliding windows; and store an indication of the vehicle event. ## Claims ### Claim 1 A system for processing telematics data streams for event detection, the system comprising: at least one data store operable to store telematics data; and at least one processor in communication with the at least one data store, the at least one processor operable to: receive a telematics data stream; define a plurality of sliding windows for the telematics data stream, each sliding window containing a portion of the telematics data stream, each sliding window overlapping with one or more neighboring sliding windows, each sliding window comprising a logical window, the logical window being adjacent with one or more neighboring logical windows of the one or more neighboring sliding windows; and identify a vehicle event based on the portion of the telematics data stream contained within one of the sliding windows. ### Claim 2 (depends on 1) The system of claim 1, wherein a start of the vehicle event occurs within one and only one of the logical windows. ### Claim 3 (depends on 1) The system of claim 1, wherein each sliding window comprises at least one buffer. ### Claim 4 (depends on 3) The system of claim 3, wherein a length of the at least one buffer is greater than the length of the vehicle event. ### Claim 5 (depends on 3) The system of claim 3, wherein the at least one buffer comprises a first buffer preceding the logical window and a second buffer following the logical window. ### Claim 6 (depends on 1) The system of claim 1, wherein a length of each logical window is equal to a distance between the start of each pair of neighboring sliding windows. ### Claim 7 (depends on 1) The system of claim 1, wherein a length of each sliding window is the same. ### Claim 8 (depends on 1) The system of claim 1, wherein a length of each logical window is the same. ### Claim 9 (depends on 1) The system of claim 1, wherein the vehicle event is a first vehicle event, one of the sliding windows is a first sliding window, and the at least one processor is further operable to: identify a second vehicle event based on the portion of the telematics data stream contained within a second sliding window. ### Claim 10 (depends on 9) The system of claim 9, wherein a start of the first vehicle event occurs within the logical window of the first sliding window and a start of the second vehicle event occurs within the logical window of the second sliding window. ### Claim 11 A method for processing telematics data streams for event detection, the method comprising operating at least one processor to: receive a telematics data stream; define a plurality of sliding windows for the telematics data stream, each sliding window containing a portion of the telematics data stream, each sliding window overlapping with one or more neighboring sliding windows, each sliding window comprising a logical window, the logical window being adjacent with one or more neighboring logical windows of the one or more neighboring sliding windows; and identify a vehicle event based on the portion of the telematics data stream contained within one of the sliding windows. ### Claim 12 (depends on 11) The method of claim 11, wherein a start of the vehicle event occurs within one and only one of the logical windows. ### Claim 13 (depends on 11) The method of claim 11, wherein each sliding window comprises at least one buffer. ### Claim 14 (depends on 13) The method of claim 13, wherein a length of the at least one buffer is greater than a length of the vehicle event. ### Claim 15 (depends on 13) The method of claim 13, wherein the at least one buffer comprises a first buffer preceding the logical window and a second buffer following the logical window. ### Claim 16 (depends on 11) The method of claim 11, wherein a length of each logical window is equal to the distance between a start of each pair of neighboring sliding windows. ### Claim 17 (depends on 11) The method of claim 11, wherein a length of each sliding window is the same. ### Claim 18 (depends on 11) The method of claim 11, wherein a length of each logical window is the same. ### Claim 19 (depends on 11) The method of claim 11, wherein the vehicle event is a first vehicle event, one of the sliding windows is a first sliding window, and the method further comprises operating the at least one processor to: identify a second vehicle event based on the portion of the telematics data stream contained within a second sliding window. ### Claim 20 (depends on 19) The method of claim 19, wherein a start of the first vehicle event occurs within the logical window of the first sliding window and a start of the second vehicle event occurs within the logical window of the second sliding window. ### Claim 21 A non-transitory computer readable medium having instructions stored thereon executable by at least one processor to implement a method for processing telematics data streams for event detection, the method comprising operating the at least one processor to: receive a telematics data stream; define a plurality of sliding windows for the telematics data stream, each sliding window containing a portion of the telematics data stream, each sliding window overlapping with one or more neighboring sliding windows, each sliding window comprising a logical window, the logical window being adjacent with one or more neighboring logical windows of the one or more neighboring sliding windows; and identify a vehicle event based on the portion of the telematics data stream contained within one of the sliding windows.
