Systems and Methods for Determining Driver Fatigue Level from Lane Variability and Geographic Location
First Claim
Patent Images
1. A method, using a processor, for determining a fatigue level of a driver of a vehicle based at least in part upon lane variability data and geographic location data for the vehicle, the method comprising:
- receiving, at the processor, lane variability data, the lane variability data corresponding to a change of position of a vehicle in a driving lane;
receiving, at the processor, geographical position data for the vehicle;
identifying, with the processor, a road segment of interest based at least in part on the received geographical data;
selecting, with the processor, a subset of the received lane variability data corresponding to the vehicle travelling over the identified road segment of interest; and
determining, with the processor, a fatigue level, F, of a driver of the vehicle based at least in part upon the selected subset of the received lane variability data.

Abstract
Systems and methods are disclosed for determining a fatigue level of a human operator of a motor vehicle based upon lane variability data and geographic position data of the vehicle, used either alone or in combination with other data such as (without limitation) vehicle operational data, vehicle environment data, road segments, and/or the like.

31. A computer program product embodied in a non-transitory medium and comprising computer-readable instructions that when executed by a suitable computer cause the computer to perform a method for determining a fatigue level of a driver of a vehicle based at least in part upon lane variability data and geographic location data for the vehicle, the method comprising:
-
receiving, at the processor, lane variability data, the lane variability data corresponding to a change of position of a vehicle in a driving lane; receiving, at the processor, geographical position data for the vehicle; identifying, with the processor, a road segment of interest based at least in part on the received geographical data; selecting, with the processor, a subset of the received lane variability data corresponding to the vehicle travelling over the identified road segment of interest; and determining, with the processor, a fatigue level, F, of a driver of the vehicle based at least in part upon the selected subset of the received lane variability data.
