Diagnosis apparatus which supports fault reproduction, and method of outputting fault reproduction data
First Claim
1. A trouble diagnosis apparatus for supporting reproduction of trouble on the basis of at least one of diagnosis trouble codes provided by an electronic control unit provided onboard a vehicle, each of the diagnosis trouble codes representing a trouble, the trouble diagnosis apparatus configured to:
- extract unique characteristics that are unique to at least one of the diagnosis trouble codes from driving data read out from electronic control units of a plurality of vehicles in trouble, for each driving parameter;
extract global characteristics that are characteristics relating to a plurality of the diagnosis trouble codes from said driving data read out from the electronic control units of the plurality of vehicles in trouble, for each driving parameter; and
for a given diagnosis trouble code, determine similarity between the unique characteristics unique to the given diagnosis trouble code and the global characteristics,out of one or more unique characteristics unique to the given diagnosis trouble code, select one or more unique characteristics that have low similarity relative to the global characteristics as the driving data for reproducing the trouble corresponding to the given diagnosis trouble code, and present the one or more selected unique characteristics for reproducing the trouble.

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.

6. In diagnosis of troubles of vehicles, a computer implemented method of presenting trouble diagnosis data for supporting reproduction of trouble on the basis of at least one of diagnosis trouble codes provided by an electronic control unit provided onboard a vehicle, each of the diagnosis trouble codes representing a trouble, the method comprising the steps of:
-
extracting unique characteristics of respective driving parameters that are unique to respective ones of the diagnosis trouble codes from driving data read out from electronic control units of a plurality of vehicles in trouble, for each driving parameter; extracting global characteristics that are characteristics relating to a plurality of the diagnosis trouble codes from said driving data read out from the electronic control units of the plurality of vehicles in trouble, for each driving parameter; determining, for a given diagnosis trouble code, similarity between the unique characteristics unique to the given diagnosis trouble code and the global characteristics; and out of unique characteristics unique to the given diagnosis trouble code, presenting one or more unique characteristics that have low similarity to the global characteristics as the driving data for reproducing the trouble corresponding to the given diagnosis trouble code. - View Dependent Claims (7, 8, 9, 10)
