Patent ID: 8655560

Claim:
A control apparatus for a vehicular drive apparatus that includes a driving power source, and a power transmission device that transmits power from the driving power source to a drive wheel, the control apparatus comprising a malfunction determination device that determines that the power transmission device is in an abnormal state when a comparison value is equal to or above a predetermined value, and determines that a malfunction occurs in the power transmission device when the power transmission device continuously remains in the abnormal state for a predetermined period, wherein: the comparison value is obtained by making a comparison between an actual value and a theoretical value that relate to a rotational speed of a predetermined rotational member that constitutes at least a part of the vehicular drive apparatus; and the malfunction determination device sets the predetermined period according to an operating state of the power transmission device, wherein the predetermined period is set using a map that shows a relationship between the predetermined period and the operating state of the power transmission device, and when an actual rotational speed of the predetermined rotational member is low, the malfunction determination device sets the predetermined period to a long period, as compared to when the actual rotational speed is high.
