Abstract
A control apparatus of a transmission includes a hydraulic pressure circuit, an abnormality detector, and a controller. The transmission performs shifting operation of the transmission. The controller controls the shifting operation by controlling, as a first control operation, a control pressure adjusting value to allow a line pressure and a control pressure to have a correlation with each other and by using, as a value of the line pressure, a value calculated on a basis of a detected value of the control pressure. The controller controls the shifting operation by controlling, as a second control operation, the control pressure adjusting valve to allow the line pressure and the control pressure to have a correlation with each other and by using, as a value of the control pressure, a value calculated on a basis of a detected value of the line pressure.
