System, method and computer program product for decoding vehicle identification numbers

摘要

A vehicle identification number (VIN) decoder (VDC) implementing a unique VIN decoding method may, for a given VIN, shorten the VIN and form a stem and a leaf therefrom. Utilizing the stem, the VDC may operate to find matching leaf values, if any, from a set of look up tables. Depending upon a match outcome, one or more trim identification code (TIC) values can be assigned to the VIN and a candidate list can be constructed utilizing the assigned TIC value(s). The candidate list, which can be optimized, may contain one or more candidate trims for the VIN. For each candidate trim, a confidence score and a match probability can be generated. The VDC may provide decoded information containing trim data associated with at least one of the one or more candidate trims for the VIN to a client device over a network connection.

主权项

1. A method for decoding a vehicle identification number (VIN), comprising:
determining, by a computer having a processor and a memory, shortened VIN (sVIN) values for the VIN; the computer determining trim identification code (TIC) values for the VIN based at least on the sVIN values; the computer determining a set of candidate trims for the VIN based at least on the TIC values; the computer determining an optimized list of candidate trims from the set of candidate trims for the VIN; the computer determining a confidence score and a match probability relative to the VIN for each candidate trim in the optimized list of candidate trims; and based on determined confidence scores and match probabilities for corresponding candidate trims in the optimized list of candidate trims, the computer selecting one or more candidate trims from the optimized list of candidate trims for output.
