In some arrangements, upon detecting a turn, sensor data may be collected to determine one or more characteristics or attributes of the turn. Such data may indicate a loss event associated with the turn and be used to calculate a probability or risk of loss given the various characteristics of the turn. These probabilities may further be applied to determine various costs and premiums. ## Claims ### Claim 1 A turn detection apparatus comprising: a communication interface; a processor; and memory storing computer readable instructions that, when executed by the processor, cause the turn detection apparatus to: detect, using at least one sensor of a vehicle, a triggering vehicle event; initiate a sliding heading detection window defined by a specified amount of time; detect a plurality of headings of the vehicle during the sliding heading detection window, each of the headings corresponding to a different point in time; determine at least one movement characteristic of the vehicle based on the plurality of headings of the vehicle detected during the sliding heading detection window; and determine a risk of loss associated with at least one of the vehicle and a driver of the vehicle based on the determined at least one movement characteristic of the vehicle. ### Claim 2 (depends on 1) The turn detection apparatus of claim 1, wherein the communication interface includes a mobile communication device. ### Claim 3 (depends on 1) The turn detection apparatus of claim 1, wherein the communication interface is configured to be physically connected to the vehicle, and wherein determining the at least one movement characteristic of the vehicle is further based on one or more sensor readings obtained from a sensor of the turn detection apparatus. ### Claim 4 (depends on 1) The turn detection apparatus of claim 1, wherein detecting the plurality of headings of the vehicle is performed using signal triangulation. ### Claim 5 (depends on 1) The turn detection apparatus of claim 1, wherein determining at least one movement characteristic of the vehicle includes determining that the vehicle has registered a turn based on a total turn angle, detected using the plurality of headings, being above a specified threshold angle. ### Claim 6 (depends on 1) The turn detection apparatus of claim 1, wherein the at least one characteristic of the turn of the vehicle includes a speed of the turn. ### Claim 7 (depends on 6) The turn detection apparatus of claim 6, wherein the at least one characteristic of the turn includes a rate of acceleration. ### Claim 8 (depends on 3) The turn detection apparatus of claim 3, wherein the at least one sensor includes a camera. ### Claim 9 (depends on 1) The turn detection apparatus of claim 1, wherein determining the risk of loss includes calculating a probability of loss based on historical loss data associated with turns having the at least one characteristic. ### Claim 10 (depends on 1) The turn detection apparatus of claim 1, wherein the turn detection apparatus is further caused to: detect a loss event within a predefined amount of time of a turn of the vehicle; and assign a value of the loss event to at least one characteristic of the turn. ### Claim 11 (depends on 10) The turn detection apparatus of claim 10, wherein detecting the loss event includes determining whether the loss event is within a predefined proximity of a location of the turn. ### Claim 12 (depends on 11) The turn detection apparatus of claim 11, wherein the loss event corresponds to another vehicle different from the vehicle registering the turn. ### Claim 13 A method comprising: detecting, by a turn detection apparatus using at least one sensor of a vehicle, a triggering vehicle event; initiating, by the turn detection apparatus, a sliding heading detection window defined by a specified amount of time; detecting, by the turn detection apparatus, a plurality of headings of the vehicle during the sliding heading detection window, each of the headings corresponding to a different point in time; determining, by the turn detection apparatus, at least one movement characteristic of the vehicle based on the plurality of headings of the vehicle detected during the sliding heading detection window; and determining, by the turn detection apparatus, a risk of loss associated with at least one of the vehicle and a driver of the vehicle based on the determined at least one movement characteristic of the vehicle. ### Claim 14 (depends on 13) The method of claim 13, wherein detecting the plurality of headings includes obtaining positioning information through a global positioning system (GPS) receiver. ### Claim 15 (depends on 13) The method of claim 13, wherein the turn detection apparatus comprises a first position detection device and a second position detection device, and wherein the method further comprises modifying a data collection rate during the sliding heading detection window depending on at least one of a signal strength of the first position detection device and a signal strength of the second position detection device. ### Claim 16 (depends on 15) The method of claim 15, wherein modifying the data collection rate includes: increasing a data collection rate of the first position detection device; and decreasing a data collection rate of the second position detection device. ### Claim 17 A non-transitory computer readable medium storing computer readable instructions that, when executed by a processor, cause a turn detection apparatus to: detect, using at least one sensor of a vehicle, a triggering vehicle event; initiate a sliding heading detection window defined by a specified amount of time; detect a plurality of headings of the vehicle during the sliding heading detection window, each of the headings corresponding to a different point in time; determine at least one movement characteristic of the vehicle based on the plurality of headings of the vehicle detected during the sliding heading detection window; and determine a risk of loss associated with at least one of the vehicle and a driver of the vehicle based on the determined at least one movement characteristic of the vehicle. ### Claim 18 (depends on 17) The non-transitory computer readable medium of claim 17, wherein the turn detection apparatus is further caused to determine whether the vehicle has turned based on whether a total turn angle, determined using the plurality of headings, is above a specified threshold angle. ### Claim 19 (depends on 17) The non-transitory computer readable medium of claim 17, wherein the at least one characteristic includes a rate of acceleration. ### Claim 20 (depends on 17) The non-transitory computer readable medium of claim 17, wherein the at least one characteristic includes a direction of a turn.
