Methods and systems for driver identification

摘要

A method of determining vehicle entry information for a user includes obtaining a yaw measurement using a mobile device, determining, using a processor, a first time span associated with a user entering a vehicle, and determining, using the processor, a second time span associated with a user exiting the vehicle. The method also includes determining that a change in magnitude over a portion of the yaw measurement is greater than a predetermined threshold over at least one of the first time span or the second time span and determining an angular change of the yaw measurement over the predetermined threshold. The method further includes associating right hand entry with the vehicle entry information if the angular orientation of the yaw measurement is clockwise and associating left hand entry with the vehicle entry information if the angular orientation of the yaw measurement is counter-clockwise.

1. A method of aligning a mobile device having an accelerometer, a gyroscope, and an alignment axis to a reference frame of a vehicle, the method comprising:
placing the mobile device in the vehicle; obtaining data from the accelerometer of the mobile device; detecting, one or more braking events and one or more forward acceleration events during a driving event; determining, using the accelerometer of the mobile device, a direction of travel of the vehicle with respect to the reference frame of the vehicle; obtaining angular measurement data from the gyroscope of the mobile device; and during the driving event, aligning, using the angular measurement data, the alignment axis of the mobile device to the reference frame of the vehicle.
