摘要： 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.

摘要： Techniques are disclosed for accessing sensor-based driving data prior to the installation of an application on a mobile device. Data corresponding to time intervals preceding the installation may be used to detect a trip by: identifying a first time at which the data indicates a high probability of vehicular activity and identifying a second time at which the data indicates a low probability of vehicular activity, wherein the second time instant occurs after the first time. The trip may correspond to a first time interval that extends between the first time and the second time.

摘要： 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.
