A failure determination threshold value HSH used for making a failure determination for a control apparatus, for example, a lock-up clutch (26) by failure determining means (116) is corrected by failure determination threshold value correcting means (114) based on a continuation quantity qNG, for example, a duration tNG, of an operation state in which a predetermined failure precondition for the control apparatus mounted on a vehicle is satisfied. Therefore, a failure determination is performed by the failure determining means (116) using the failure determination threshold value HSH obtained in consideration of individual differences such as variations between vehicles. As a result, it is possible to prevent an erroneous determination regarding a failure, and to improve sensitivity of a failure determination. |
