Abstract: Apparatuses and methods for determining a route are provided. In some examples, the method comprises: receiving measurements of one or more motion sensors of a mobile device disposed in a vehicle; selecting, based on a start time and an end time of a first route, a subset of the measurements; determining, based on the subset of the measurements, turns or stops made by the vehicle as part of the first route and their directions; determining, based on the subset of the measurements, distances of path segments traveled by the vehicle between the turns or stops; constructing an estimated route including a sequence of the turns or stops and path segments; selecting, based on comparing the estimated route and a plurality of candidates routes from a map, the first route; and displaying the map including the first route.

Abstract: Techniques are disclosed for accessing sensor-based driving data that includes detecting a waking event associated with an application and activating the application in response to detecting the waking event. Activity data for a recorded time interval preceding the waking event may be used to detect a missed trip by: identifying a first time in which the activity data indicates a high probability of automotive activity and identifying a second time in which the activity data indicates a low probability of automotive activity, wherein the second time instant occurs after the first time. The missed trip may correspond to a first time interval that extends between the first time and the second time. Sensor data may then be received for a second time interval that begins prior to the first time and ends after the second time.

Abstract: Techniques are disclosed for predicting a confidence of a total loss event. A mobile device detects a crash event using one or more sensors of a mobile device. The mobile device records a first set of data from the one or more sensors of the mobile device. The mobile device generates a first feature vector including the first set of data and vehicle data that includes an identifier of a vehicle. The mobile device generates a second feature vector using the first set of data and additional data types. The mobile device predicts a confidence of a total loss event by generating a first confidence value from a first machine-learning model using the first feature vector and a second confidence value from a second machine-learning model using the second feature vector.
