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).

Claims20

Dependent claims

A method comprising:

operating an accelerometer of a mobile device disposed in a vehicle during a drive to obtain acceleration measurement data;
operating a global positioning system (GPS) receiver of the mobile device disposed in the vehicle during the drive to obtain location measurement data;
verifying, by a processor of the mobile device, a portion of the acceleration measurement data with a first verification approach using the location measurement data corresponding in time to the portion of the acceleration measurement data;
removing, by the processor, a first portion of the acceleration measurement data that is not verified by the first verification approach from the acceleration measurement data to provide a first remaining portion of the acceleration measurement data;
and
determining, by the processor, a movement event for the vehicle using the first remaining portion of the acceleration measurement data.

operating a global positioning system (GPS) receiver of the mobile device disposed in the vehicle during the drive to obtain location measurement data;
verifying, by a processor of the mobile device, a portion of the second acceleration measurement data with a first verification approach using the location measurement data corresponding in time to the portion of the second acceleration measurement data;
removing, by the processor, a first portion of the second acceleration measurement data that is not verified by the first verification approach from the second acceleration measurement data to provide a first remaining portion of the second acceleration measurement data;
and
determining, by the processor, a movement event for the vehicle using the first remaining portion of the second acceleration measurement data;
and
generating during the drive, by the mobile device, a notification to the user about the movement event.
