Abstract

A control apparatus includes: a gear-shift prediction unit (31) that predicts whether a power-on downshift using a clutch-to-clutch shift operation needs to be performed as a next gear-shift; and a standby pressure supply control unit (32) that supplies a pressure for placing a first friction engaging element, which contributes to the next gear-shift, in the standby state, which is achieved immediately before engagement of the first friction engaging element is started, to the first friction engaging element, when the gear shift prediction unit (31) predicts that the power-on downshift using the clutch-to-clutch shift operation needs to be performed as the next gear-shift. When it is determined that a condition for performing the next gear-shift is satisfied based on the accelerator operation and the vehicle drive state, a shift command signal (Ia to Ie) is output to bring the first friction engaging element out of the standby state and engage the first friction engaging element
