DIAGNOSIS APPARATUS FOR ASSISTING A TROUBLE REPRODUCTION AND A METHOD FOR PRESENTING DATA FOR REPRODUCING TROUBLE
First Claim
1. A trouble diagnosis apparatus for supporting reproduction of trouble based on a trouble code provided by an electronic control unit provided onboard a vehicle, the trouble code representing a trouble, comprising:
- from driving data associated with a plurality of driving parameters, the driving data provided by electronic control units of a plurality of failed vehicles, means for extracting, for at least one of the trouble codes, characteristics unique to the trouble code with respect to respective driving parameters;
means for extracting, from said driving data associated with a plurality of trouble codes, global characteristics associated with a plurality of said trouble codes with respect to each one of said driving parameters; and
for said at least one of the trouble codes, means, based on similarity between the characteristics unique to the trouble code and said global characteristics, for setting the portion of the characteristics unique to the trouble code that have low similarity as the driving data for reproducing the trouble corresponding to the trouble code.

Abstract
A trouble diagnosis apparatus which supports reproduction of trouble according to a trouble code provided from an electronic control unit of the vehicle. The apparatus comprises means for extracting, for at least one of the trouble codes, characteristics unique to the trouble code with respect to respective driving parameters, means for extracting, from said driving data associated with a plurality of trouble codes, global characteristics associated with a plurality of said trouble codes with respect to each one of said driving parameters, and for said at least one of the trouble codes, means, based on similarity between the characteristics unique to the trouble code and said global characteristics, for setting the portion of the characteristics unique to the trouble code that have low similarity as the driving data for reproducing the trouble corresponding to the trouble code.

7. In diagnosis of troubles of vehicles, a computer implemented method of presenting trouble diagnosis data for supporting reproduction of trouble based on a trouble code provided by an electronic control unit provided onboard a vehicle, the trouble code representing a trouble, the method comprising the steps of:
-
extracting from driving data associated with a plurality of driving parameters, the driving data provided by electronic control units of a plurality of failed vehicles, for at least one of the trouble codes, characteristics unique to the trouble code with respect to respective driving parameters; extracting, from said driving data associated with a plurality of trouble codes, global characteristics associated with a plurality of said trouble codes with respect to each one of said driving parameters; determining, for said at least one of the trouble codes, similarity between the characteristics unique to the trouble code and said global characteristics; and presenting the portion of the characteristics unique to the trouble code that have low similarity as the driving data for reproducing the trouble corresponding to the trouble code. - View Dependent Claims (8, 9, 10, 11, 12)
