PROBLEM TO BE SOLVED: To provide a hydraulic control device capable of keeping power required for discharging oil to a required minimum while responding to a change in viscosity of the oil.SOLUTION: An ECU 100 feedbacks an actual discharge oil pressure Pm actually discharged from an oil pump 5 and performs PID control on a target discharge oil pressure Pf for the oil pump 5 to calculate a required discharge oil pressure Po required for the oil pump 5. Besides, the ECU 100 sets a gain G common to a proportional term Tp, an integration term Ti and a differential term Td in the PID control. The gain G common thereto is calculated on the basis of the oil temperature of oil. |
