SYSTEM FOR PREDICTING DRIVER BEHAVIOR
First Claim
1. A system for predicting behavior of other vehicles, the system comprising:
- a sensor for sensing a condition, the sensor having an output for outputting signals representing different conditions;
a driver predictor for receiving information and maintaining a hierarchal temporal memory structure indicative of a current vehicle condition relative to the other vehicles, the driver predictor having an input and an output, the input of the driver predictor coupled to the output of the sensor, the driver predictor receiving signals from the sensor and converting them to data for storage in the hierarchal temporal memory structure; and
an output unit for generating an output signal related to the current vehicle condition, the output unit having an input and an output, the input of the output unit coupled to the driver predictor.

Abstract
A system and method for predicting driver behavior and generating control and/or warning signals comprises: one or more sensors; a database; a driver predictor for generating warning and control signals; a notification unit; and a vehicle control unit. More specifically, the driver predictor includes a transfer module, a hierarchical temporal memory and a prediction retrieval module. The transfer module is used to receive data and translate it into a form so that it can be stored in the hierarchical temporal memory. The hierarchical temporal memory receives data input and stores it such that data items are translated into short-term memory items which are in turn translated into intermediate-term data which in turn are finally translated into long-term data. The translation of data from one level of the memory to another is performed according to the present invention such that the data at each level of memory is reflective of and predictive of a particular driver behavior. Once the data is stored in the memory, the prediction retrieval module accesses the hierarchical temporal memory to generate warning signals to alert the driver of potentially dangerous conditions and/or control systems of the vehicle to prevent or avoid collisions. The present invention also includes a variety of method including a method for storing driving data in a hierarchical temporal memory, and a method for using a hierarchical temporal memory to generate collision avoidance signals.
