Abstract
A control apparatus for a vehicular power transmitting apparatus includes a first valve that controls the supply of hydraulic fluid to a running clutch in connection with the switching of the operating state of a first solenoid valve; a second valve that controls the supply of hydraulic fluid to a lockup clutch in connection with the switching of the operating state of a second solenoid valve; and a linear solenoid valve that selectively controls the apply force of the running clutch and the lockup clutch according to the supply of control pressure to the first valve and the second valve. The control apparatus detects a failure state of a part related to the operation of the power transmitting apparatus by the operating state of the running clutch and the operating state of the lockup clutch.
