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, placing a client computing device in a vehicle, 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 originating from a client computing device, wherein the client computing device includes an accelerometer, is placed in a vehicle and free to move with respect to movement of the vehicle;
• summarize the plurality of telematics data at a specified sample rate;
• split the telematics data into one or more temporal segments;
• shift down one or more temporal segments by at least one data point;
• convert the plurality of telematics data from a time domain to a spectral domain;
• select one or more data points from the converted telematics data;
• determine that a total spectral power of the selected data points meet a threshold value;
• and
• identify a first primary movement window including the selected data points if the total spectral power of the selected data points does not meet the threshold value,
• wherein the identified first primary movement window has a total spectral power that does not meet a threshold spectral value, the primary movement window being indicative of the accelerometer being static with respect to the vehicle while in the vehicle and a total spectral power of the selected data points that meets the threshold value is indicative of the accelerometer moving with respect to the vehicle while in the vehicle.

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 originating from a client computing device, wherein the client computing device is placed in a vehicle, and the client computing device is free to move with respect to movement of the vehicle, and wherein the client computing device includes an accelerometer;
• summarize the plurality of telematics data at a specified sample rate;
• split the telematics data into one or more temporal segments;
• shift down one or more temporal segments by at least one data point;
• convert the plurality of telematics data from a time domain to a spectral domain;
• select one or more data points from the converted telematics data;
• determine that a total spectral power of the selected data points meet a threshold value;
• and
• identify a first primary movement window including the selected data points if the total spectral power of the selected data points does not meet the threshold value, wherein the identified first primary movement window has a total spectral power that does not meet a threshold spectral value, the primary movement window being indicative of the accelerometer being static with respect to the vehicle while in the vehicle and a total spectral power of the selected data points that meets the threshold value is indicative of the accelerometer moving with respect to the vehicle while in the vehicle.
