METHODS AND SYSTEMS FOR ALIGNING A MOBILE DEVICE TO A VEHICLE

摘要

A method of determining vehicle acceleration information includes obtaining a plurality of movement measurements from a mobile device in a vehicle, and determining a plurality of gravity vectors, each of the plurality of gravity vectors associated with at least two of the plurality of movement measurements. The method further includes removing a movement measurement from the plurality of movement measurements using the plurality of gravity vectors to provide a set of remaining movement measurements. An acceleration measurement for the vehicle is determined using the remaining movement measurements.
