Method and system for diagnosing and reporting failure of a vehicle emission test
First Claim
1. A method for generating a diagnosis of a vehicle'"'"'s cause of failure of an emissions test, comprising the steps of:
- in a storage media, storing a classifier table composed of a set of rules;
in an emissions testing facility, receiving and storing vehicle characteristics signals;
in said emissions testing facility, sampling emissions of said vehicle to create emission test results to generate a series of emission test signals;
transmitting to a processor said emissions test signals;
transmitting to said processor said vehicle characteristics signal; and
comparing said emission test signals and said vehicle characteristics signals to said classifier table'"'"'s set of rules in a manner in which forms said diagnoses of said vehicle'"'"'s cause of failure and generating a prediction report thereof.

Abstract
Disclosed is a system and method which systematically diagnoses emissions test failure by applying the rules of a knowledge base to predict the cause of vehicle emissions failures. Classifiers are used to form predictions. The classifier is the data structure used in the automobile emission testing inspection lane by the lane diagnostic subsystem to provide a diagnosis for a particular vehicle. Its output is the likelihood that a vehicle suffers from a given failure based on the values of characteristics such as its emissions test results and the vehicle'"'"'s description. The classifier predictions are then used to prepare a failure report that is given to the motorist for use by his or her repair technician. In another feature of this invention, the classifiers are continuously updated in a learning process based on new repair records. The learning processes periodically analyzes the data and updates the knowledge base to include new or revised classifiers.
