1. A method comprising:
- operating a movement sensor of a mobile device disposed in a vehicle to obtain a plurality of movement measurements;
operating a location sensor of the mobile device disposed in the vehicle to obtain a plurality of location measurements;
verifying, by a processor of the mobile device, a portion of the plurality of movement measurements using the plurality of location measurements;
removing, by the processor, one or more movement measurements that are not verified from the plurality of movement measurements to provide a set of remaining movement measurements; and
determining, by the processor, a movement event for the vehicle using the set of remaining movement measurements.

Abstract
According to some embodiments of the invention, movement measurements may be obtained from a movement sensor (e.g., an accelerometer) of a mobile device in a vehicle. In addition, location measurements may be obtained from a location sensor (e.g., a GPS) of the mobile device in the vehicle. The movement measurements and the location measurements may be cross-referenced to each other to remove erroneous measurements, such as physically impossible measurements. The remaining measurements may be used to draw conclusions about the movements or locations, such as to identify a movement event (e.g., a braking event, an acceleration event, or the like).
