制御装置。An oil accumulator that has a compression spring for setting oil pressure, an on-off valve for draining, and an oil pressure sensor, and is connected to an oil pump for automatic transmission, a throttle sensor that transmits the opening of the throttle valve of an internal combustion engine, and a throttle valve. A desired hydraulic pressure characteristic value over time from the start pressure to the end pressure of the accumulator is programmed in advance for each opening degree of the accumulator. This microcomputer closes the opening/closing valve when the signal value from the oil pressure sensor is equal to or less than the temporal oil pressure characteristic value in each signal value from the throttle sensor, and the oil pressure in the accumulator increases. When the signal from the oil pressure sensor reaches the time-dependent oil pressure characteristic value, the on-off valve is opened to drain the oil in the accumulator, and the oil pressure in the accumulator is made to match the time-dependent oil pressure characteristic value of the microcomputer. A hydraulic control device for an automatic transmission for an automobile, comprising:
