Decision enhancement system for a vehicle safety restraint application
First Claim
1. A decision enhancement system configured to influence a deployment determination of a safety restraint application for a vehicle by communicating an at-risk-zone determination to the safety restraint application, said decision enhancement system comprising:
- a sensor subsystem, said sensor subsystem providing for a sensor to capture a plurality of sensor readings, said plurality of sensor readings including a first sensor reading and a second sensor reading;
a tracking subsystem, wherein said tracking subsystem provides for selectively identifying a tracked condition from a plurality of pre-defined conditions, said plurality of pre-defined conditions including a crash condition, wherein said tracked condition is selectively identified using said first sensor reading; and
a detection subsystem, wherein said detection subsystem is invoked only after said tracking subsystem selectively identifies said crash condition as said tracked condition, wherein said detection subsystem generates said at-risk-zone determination, from said second sensor reading, and wherein said second sensor reading is not captured earlier than said first sensor reading.

Abstract
The disclosure describes systems and methods that pertain to interactions between a vehicle and an occupant within the vehicle. More specifically, various systems and methods for enhancing the decisions of automated vehicle applications (collectively “decision enhancement system”) are disclosed. In a safety restraint embodiment, a sensor is used to capture various sensor readings. Sensor readings are typically in the form of images. Occupant information, such as location attributes, motion attributes, and occupant category attributes can be obtained from the sensor readings. If the system concludes that the deployment of a safety restraint is potentially justified, an at-risk-zone detector can be used to determine whether or not the occupant will be too close to the deploying safety restraint at the time of deployment for the safety restraint to be safely deployed.

22. A safety restraint system for a vehicle, comprising:
-
a sensor, a plurality of sequential sensor images, a spatial area, a computer, a plurality of occupant attributes, a current condition, a plurality of pre-defined conditions, a deployment condition, a non-deployment condition, a detection heuristic, an at-risk-zone flag value, a safety restraint deployment mechanism;
wherein said sensor is configured to capture said plurality of sequential sensor images of said spatial area;
wherein said computer provides for;
tracking said plurality of occupant attributes from said plurality of sequential images;
selectively identifying said current condition from said plurality of pre-defined occupant conditions, wherein said plurality of pre-defined conditions includes said deployment condition and said non-deployment condition;
invoking said detection heuristic after selectively identifying said deployment condition as said occupant condition;
using said detection heuristic to set said at-risk-zone flag value;
communicating said at-risk-zone flag value to said safety restraint deployment mechanism;
wherein said safety restraint deployment mechanism selectively precludes the deployment of said safety restraint when said occupant condition is said deployment condition, and when said at-risk-zone flag value is yes. - View Dependent Claims (23)

24. A method for installing a decision enhancement application into a vehicle that includes a deployment mechanism for a safety restraint device, the method comprising:
-
defining an at-risk-zone corresponding to a location of the deployment mechanism within the vehicle;
configuring a sensor to transmit sensor images to a computer;
instructing the computer to filter out all areas within the image that are not part of a window-of-interest corresponding to the defined at-risk-zone after receiving a preliminary determination that a deployment of the safety restraint device is necessary;
programming the computer to set an at-risk-zone flag corresponding to a detection of an occupant within the at-risk-zone, wherein the at-risk-zone flag is set using at least one window-of-interest image filtered by the computer; and
placing the sensor and computer within the vehicle. - View Dependent Claims (25, 26, 27, 28)
