Monitoring of vehicle health based on historical information
First Claim
1. A method of detecting abnormal behavior in a vehicle having an engine with an engine control module, said method comprising:
- providing a database, a communication device, and an interface to a diagnostic port of an engine control module;
retrieving engine parameters from the engine control module through said interface during a driving experience and uploading the retrieved engine parameter to said database using said communication device;
analyzing the uploaded engine parameters from multiple driving experiences at said database to establish historical data and determining normal operation of particular retrieved engine parameters based on the historical data; and
comparing engine parameters of a vehicle to be diagnosed with said normal operation of particular retrieved engine parameters to determine whether the vehicle to be diagnosed operates outside or the normal operation.

Abstract
A method and apparatus for detecting abnormal behaviour in a vehicle (8) with an engine having engine control module includes providing a database (20), and a vehicle analyzer (12) having a communication device (16) and an interface (14) that links the communication device (16) to a vehicle (8). Engine parameters that are retrieved through the interface (14) during driving experience are uploaded to the database (20) using the communication device (16). The database (20) analyzes the engine parameters from multiple driving experiences to establish historical data and determine normal operation of particular retrieved engine parameters based on the historical data. A vehicle (8) can be diagnosed by comparing its retrieved engine parameters with the database (20).

13. A method of detecting abnormal behavior in a vehicle having an engine with an engine control module, said method comprising:
-
providing a database and multiple vehicle analyzers, each of said vehicle analyzers including a communication device and an interface to a diagnostic port of an engine control module, retrieving engine parameters from the engine control module of multiple vehicles that are generally the same type as each other using said multiple vehicle analyzers and uploading the retrieved engine parameters to said database;
analyzing the uploaded engine parameters from the multiple vehicles to establish historical data and determining normal operation of particular retrieved engine parameters based on the historical data; and
comparing engine parameters of a vehicle generally of said same type with said normal operation of particular retrieved engine parameters to determine whether that vehicle operates outside of the normal operation. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22)

23. A system for detecting abnormal vehicle engine behavior of a vehicle having an engine with an engine control module, comprising:
-
a vehicle analyzer comprising a communication device and an interface diagnostic scan tool that links said communication device to a diagnostic port of a vehicle engine control module;
a database system separate from said vehicle analyzer, said database system being programmed to receive data uploaded by said communication device, said database determines normal operation of particular engine parameters based on historical data;
wherein said vehicle analyzer retrieves data from the vehicle while the vehicle is driven to retrieve engine parameters and uploads the retrieved engine parameters to said database;
said database system compares the collected data to said normal operation of particular engine parameters to determine abnormal conditions of the vehicle. - View Dependent Claims (24, 25, 26, 27, 28, 29, 30, 31, 32, 33)

34. A system for detecting abnormal vehicle engine behavior of a vehicle having an engine with an engine control module comprising:
-
a database and a plurality of vehicle analyzers, each including a communication device and an interface diagnostic scan tool that links that communication device to a diagnostic port of a vehicle engine control module, wherein said communication device is adapted to upload to said database engine parameters retrieved by said interface diagnostic scan tool; and
said database is adapted to analyze the retrieved engine parameter uploaded from said plurality of vehicle analyzers to establish historical data among vehicles that are generally of the same type and to determine normal operation of particular retrieved engine parameters based on historical data;
wherein said database is further adapted to compare engine parameters of a vehicle generally of said same type with said normal operation of particular retrieved engine parameters to determine whether that vehicle operates outside of the normal operation. - View Dependent Claims (35, 36, 37, 38, 39, 40, 41, 42, 43)
