Real-time detection of hazardous driving
First Claim
Patent Images
1. A method for real-time detection of hazardous driving comprising:
- collecting first data about driver control signals applied to a vehicle moving along a path;
collecting second data about the motion of the vehicle along the path;
detecting roadside signs along the path as the vehicle moves toward them, by;
scanning the roadside along the path to detect roadside signs;
capturing images of the roadside; and
processing the captured images to identify roadside signs based on size and shape of the roadside signs;
determining content of the roadside signs detected along the path;
comparing the detected content of the roadside signs with the driver control signals and the motion of the vehicle; and
in response to the step of comparing, providing information with regard to the operation of the vehicle.

Abstract
A system is disclosed which provides real-time detection of hazardous driving behavior. The system collects information about the motion of a vehicle along a path, for example, using a global positioning satellite system receiver. Roadside signs along the path are detected and their content determined. That information is compared with information about the motion of the vehicle to provide information with regard to potentially hazardous driving behavior.

13. A method for real-time detection of hazardous driving comprising:
-
collecting data about driver control signals applied to a vehicle moving along a path; using global positioning satellites collecting data about the motion of a vehicle along the path; detecting roadside signs along the path as the vehicle moves toward them; determining content of the roadside signs detected along the path; comparing the detected content of the roadside signs with the data about driver control signals and the motion of the vehicle; and in response to the step of comparing, providing information with regard to the operation of the vehicle, wherein the information with regard to the operation of the vehicle comprises information regarding whether the vehicle is consuming excessive fuel. - View Dependent Claims (14, 15, 16)

17. An apparatus for real-time detection of hazardous driving comprising:
-
an input for receiving data about driver control signals applied to a vehicle moving along a path; a global positioning satellite system receiver for collecting information about motion of a vehicle along the path; a scanner for detecting roadside signs along the path as the vehicle moves toward them, by; scanning the roadside along the path to detect roadside signs; and capturing images of the roadside; a processor for determining content of the roadside signs detected along the path by processing the captured images to identify roadside signs based on size and shape of the roadside signs, and comparing the detected content of the roadside signs with the data about driver control signals and the motion of the vehicle and in response providing information with regard to the operation of the vehicle, wherein the information with regard to the operation of the vehicle comprises information regarding whether the vehicle is consuming excessive fuel. - View Dependent Claims (18, 19, 20, 21, 22, 23)
