Abstract
A control apparatus of an automatic transmission includes a first anomaly determination device and an energization interrupting device. The first anomaly determination device is configured to determine whether high-pressure anomaly has occurred in a first pressure regulating device. The high-pressure anomaly is to cause the first pressure regulating device to perform regulation to high pressure only. The energization interrupting device is configured to interrupt energization to a first switching device in a case where the first anomaly determination device determines that the high-pressure anomaly has occurred in the first pressure regulating device and in a state where a first switching valve is located at a first position connected to a first oil passage so as to supply hydraulic pressure of a hydraulic oil regulated by the first pressure regulating device to a second clutch.
