System and method for identifying heading of a moving vehicle using accelerometer data

A computer device for determining a range of yaw angle estimates, the device comprising:

• one or more processors;
• and
• one or more memories coupled to the one or more processors;
• wherein the one or more memories include non-transitory computer executable instructions stored therein that, when executed by the one or more processors, cause the one or more processors to:
• receive, via a computer network, a plurality of telematics data originating from a client computing device;
• determine a first primary movement window from the plurality of telematics data;
• remove the effect of gravity from the plurality of telematics data;
• determine a potential range of yaw angles from the plurality of telematics data in the first primary movement window;
• generate one or more yaw angle estimates;
• and
• determine, a driving pattern based at least on one of the yaw angle estimates.

A computer readable storage medium comprising non-transitory computer readable instructions stored thereon for determining a range of yaw angle estimates, the instructions when executed on one or more processors cause the one or more processors to:

• receive, via a computer network, a plurality of telematics data originating from a client computing device;
• summarize the plurality of telematics data at a specified sample rate;
• remove the effect of gravity from the plurality of telematics data;
• determine an a potential range of yaw angles from the telematics data from the first primary movement window;
• generate one or more yaw angles from the potential range of yaw angles;
• and
• determining, by the one or more processors, a driving pattern based at least on one of the yaw angles.
