Failure-diagnosis information collection system

A failure-diagnosis information collection system comprising:

• a vehicle abnormality detection device for detecting a plurality of abnormality items, the vehicle abnormality detection device including a decision unit for deciding whether a detected one of the plurality of abnormality items has actually occurred, and if a time during which the decision unit continuously decides whether the abnormality has occurred reaches an abnormality confirmation time, storing abnormality information signifying that the abnormality has occurred, wherein:
• the abnormality confirmation time varies depending on the abnormality detection device;
• and
• the vehicle abnormality detection device includes a plurality of units storing time-instant information associated with an abnormality recognition time at which the decision unit changes from deciding that no abnormality has occurred to deciding that an abnormality has occurred, the time-instant information stored as an abnormality unconfirmed decision;
• wherein:
• each of the plurality of units included in the vehicle abnormality detection device stores time-instant information associated with a time at which abnormality information is stored as an abnormality confirmation time;
• and
• each of the time-instant information associated with the abnormality recognition time and the time-instant information associated with the time at which abnormality information is stored as the abnormality confirmation time global timer value originating from a clock.
