Methods and apparatus for vehicle operation analysis
First Claim
1. A method to monitor, evaluate and quantify vehicle behavior, the method comprising:
- processing, using a mobile device including a processor, image data obtained by a camera showing an environment including a) at least a portion of a vehicle and b) objects external to and in proximity to the vehicle, wherein the objects comprise a traffic sign, and wherein processing the image data comprises using a component analysis of the image data to isolate features in the image data to identify the objects in relation to the vehicle and to identify the traffic sign among the objects based on at least one of a shape, color, or content of the traffic sign;
identifying, using the mobile device, a driver event using a pattern of objects including the traffic sign and the vehicle in the image data, the driver event involving the traffic sign and associated with a driver event rule specifying a reference vehicle operating behavior for the driver event, the driver event rule including observance of the traffic sign;
measuring, using the mobile device, a geographic location of the vehicle using a received signal indicating the geographic location of the vehicle;
determining, using the mobile device, an operating state of the vehicle using a received indication of vehicle motion;
evaluating, using the mobile device, compliance with the driver event rule for the driver event by at least;
a) calculating a proximity of the traffic sign to the vehicle based on a distance between the vehicle and the traffic sign and ii) the operating state of the vehicle, the distance determined using the geographic location of the vehicle and a geometry between the vehicle and the traffic sign extracted from the image data; and
b) comparing the proximity of the traffic sign and the operating state of the vehicle to determine an actual vehicle operating behavior; and
c) generating a score associated with operation of the vehicle by comparing the actual vehicle operating behavior with the reference vehicle operating behavior; and
outputting, using the mobile device, a profile of the actual vehicle operating behavior including the score to quantify an evaluation of the actual vehicle operating behavior.

Abstract
Methods and apparatus are disclosed to monitor and evaluate vehicle operator behavior. An example method includes processing, using a particularly programmed processor, image data obtained with respect to a vehicle to identify an object in the image data. The example method includes measuring, using the mobile device, a geographic location of the vehicle. The example method includes determining, using the mobile device, an operating state of the vehicle. The example method includes analyzing the object in the image data, the geographic location, and the operating state of the vehicle to determine a behavior of the vehicle. The example method includes generating a score for a driver associated with the vehicle by comparing the behavior of the vehicle with a reference behavior, the reference behavior quantified by one or more driving metrics. The example method includes outputting the score.
