摘要： A method for detecting airbag deployment includes operating a plurality of sensors of the mobile device disposed in a vehicle during a drive to obtain a plurality of measurement signals, determining a change in at least one measurement signal of the plurality of measurement signals and that the change exceeds a first threshold. In response to determining that the change exceeds the first threshold, obtaining a pressure measurement signal from a pressure sensor of the plurality of sensors, determining a derivative of the pressure measurement signal, and determining that the derivative of the pressure measurement signal exceeds a second threshold. In response to determining that the derivative of the pressure measurement signal exceeds the second threshold, detecting a deployment of a vehicle airbag based on the change in the at least one measurement signal exceeding the first threshold and the derivative of the pressure measurement signal exceeding the second threshold.

摘要： Embodiments of the present invention relate to transportation systems. More particularly, embodiments relate to methods and systems of vehicle data collection by a user having a mobile device. In a particular embodiment, vehicle data (also termed herein “driving data” or “data”) is collected, analyzed and transformed, and combinations of collected data and transformed data are used in different ways, including, but not limited to, predicting, detecting, and reconstructing vehicle accidents.

摘要： A system includes: a mobile device comprising a plurality of sensors; a display device; a memory that stores instructions; and a processor. The processor is configured to execute the instructions to: operate the plurality of sensors over a plurality of time intervals during a trip in a vehicle to collect driving data; detect, using the driving data, a driving event that occurred during the trip and cause the mobile device to collect additional data associated with the trip in response; receive the additional data associated with the trip; determine that a vehicle accident event occurred during the trip based on the driving data and the additional data; and cause the display device to output an indication of the vehicle accident event.
