Hydraulic control apparatus of automatic transmission, and vehicle

A hydraulic control apparatus of an automatic transmission that performs shifting of a vehicle by engaging and opening a hydraulic clutch, the hydraulic control apparatus comprising:

• an electromagnetic proportional valve that is disposed in a hydraulic circuit and performs pressure regulation of operating oil supplied to the hydraulic clutch;
• a pressure sensor that detects an oil pressure of the operating oil supplied to the hydraulic clutch;
• and
• a control apparatus that executes filling of the hydraulic clutch with the operating oil and causes the hydraulic clutch to transition from an opened state to an engaged state by outputting, according to a control map stored in advance, a pulsed control current having a predetermined current value and a predetermined application time to the electromagnetic proportional valve, wherein
• the control apparatus performs correction processing of correcting the predetermined current value and the predetermined application time at a predetermined timing such that the oil pressure of the operating oil supplied to the hydraulic clutch is within a predetermined target pressure range when the control apparatus outputs the pulsed control current to the electromagnetic proportional valve, the predetermined current value and the predetermined application time being stored in the control map.
