Abstract: A control apparatus of an automatic transmission includes an electric hydraulic pump including a motor and a pump, an actuator for engaging or releasing a friction element by controlling a hydraulic pressure discharged from the pump, and a transmission control unit (TCU) for correcting a control signal to control the actuator depending on a dynamic characteristic coefficient of the friction element and the actuator during shifting when outputting the control signal to the actuator.
