<p>A control device for an automatic transmission including a hydraulic actuator that is actuated on the basis of a hydraulic pressure supplied and a linear solenoid valve that controls the hydraulic pressure supplied to the hydraulic actuator on the basis of a driving current of a solenoid includes an ECU that executes current feedback control over a current value of the driving current that is flowed to the solenoid using at least a proportional term and an integral term on the basis of a deviation (ΔI) between a target current value (Itgt) and actual current value (Ir) of the solenoid such that the hydraulic pressure supplied to the hydraulic actuator becomes a target hydraulic pressure. The ECU increases a proportional gain (Kp) in the current feedback control as a fluid temperature (To) detected by a fluid temperature sensor increases.</p> |
