EXTRA-VEHICULAR THREAT PREDICTOR
First Claim
1. A method of facilitating safe operation of a vehicle, the vehicle having a vehicle operator and having a vehicle environment including an object, the method comprising:
- obtaining sensor data relating to the vehicle environment;
predicting a vehicle path within the vehicle environment, the vehicle path having a vehicle path uncertainty;
predicting an object path for the object within the vehicle environment;
identifying a collision risk if the vehicle path and the object path intersect;
identifying a vehicle risk if the vehicle path uncertainty is greater than a threshold uncertainty; and
providing an alert on identifying the collision risk or the vehicle risk, the alert facilitating the safe operation of the vehicle.

Abstract
An apparatus for facilitating the safe operation of a vehicle comprises a sensor system, a sensor signal to object identifier, and a world model implemented using, for example, a multiple-input multiple-output (MIMO) algorithm such as a spiking neuron algorithm. Alerts may be provided to the vehicle operator under several conditions, such as the identification of a collision risk between the vehicle and an object, identification of a vehicle risk due to excessive uncertainty in the predicted vehicle path, or identification of an object risk due to excessive uncertainty in a predicted object path.

-
collecting sensor data representative of the vehicle environment; identifying the object within the vehicle environment using the sensor data; creating a world model, the world model including an object model for the object and a vehicle model for the vehicle; detecting changes in the world model at intervals; predicting a vehicle path for the vehicle from changes in the world model, the vehicle path having a vehicle path uncertainty; predicting an object path from changes in the world model, the object path having an object path uncertainty; and providing a collision risk alert if a collision between the vehicle and the object is predicted from the vehicle path and the object path, providing a vehicle risk alert if the vehicle path uncertainty exceeds a vehicle uncertainty threshold, and providing an object risk alert if the object path uncertainty exceeds an object uncertainty threshold, so as to facilitate the safe operation of the vehicle.
