Abstract
The disclosure reduces the number of factors to be considered in the switching control of the shift stages, thereby simplifying the switching control. In a control device of an automatic transmission, when a detection part detects that a shift position has been switched from one of a forward range and a reverse range to the other, among multiple hydraulic friction engagement mechanisms, a hydraulic pressure command value is fixed for the hydraulic friction engagement mechanisms that do not change the engaged state between the forward range and the reverse range, and the hydraulic pressure command value is variable based on a hydraulic pressure supplied to the hydraulic friction engagement mechanisms for the hydraulic friction engagement mechanisms that change the engaged state between the forward range and the reverse range.
