System and method for identifying primary and secondary movement using spectral domain analysis

A computer device for determining a primary movement window from a vehicle trip, wherein the computer device is placed in a vehicle and free to move with respect to movement of the vehicle, the computer device comprising:

• one or more processors;
• and
• one or more memories coupled to the one or more processors,
• the one or more memories including 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 including multi-axis accelerometer data,
• select one or more data points from the plurality of telematics data,
• determine whether a total spectral power of the one or more data points meets a threshold value based upon a kernel smoothed estimate using the multi-axis accelerometer data, and
• identify a primary movement window including the one or more data points based upon determining that the total spectral power of the one or more data points is less than the threshold value.

A computer readable storage medium comprising non-transitory computer readable instructions stored thereon for determining a primary movement window from a vehicle trip, 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 including multi-axis accelerometer data;
• select one or more data points from the plurality of telematics data;
• determine whether a total spectral power of the one or more data points meets a threshold value based upon a kernel smoothed estimate using the multi-axis accelerometer data;
• and
• identify a primary movement window including the one or more data points based upon determining that the total spectral power of the one or more data points is less than the threshold value.
