HYDRAULIC CONTROL DEVICE AND HYDRAULIC CONTROL METHOD FOR AUTOMATIC TRANSMISSION

As a driving source, an engine and an assist motor are provided. An engine control module includes a torque assist control unit for controlling the assist motor by a plurality of types of switching patterns having different torque assist levels. A CVT control unit includes a torque assist coordination control unit that, when a torque assist request is input from the torque assist control unit, carries out the control that increases commanded hydraulic pressure so as to increase the hydraulic pressure of hydraulically operated members. When carrying out the control that increases the commanded hydraulic pressure, the torque assist coordination control unit unifies the levels of the commanded hydraulic pressure regardless of the types of the switching patterns.
