    Abstract: In control apparatus and method for an automatic transmission, a gear shift state of a stepwise variable transmission mechanism is controlled to a target gear shift state by releasing a first engagement section according to a reduction in a capacity of the first engagement section and, simultaneously, by engaging a second engagement section according to an increase in the capacity of the second engagement section, in accordance with a torque inputted to the stepwise variable transmission mechanism and, during an inertia phase, either one of the first and second engagement sections functions as a gear shift state control side engagement section and the capacity of a gear shift state non-control side engagement section which is the other engagement section is increased when determining that it is impossible to make the gear shift state follow up the target gear shift state at the gear shift state control side engagement section.

    Abstract: A control system controls an automatic transmission. The automatic transmission comprises a stepwise variable transmission section that includes a plurality of frictional elements and establishes a desired speed by a shift change disengaging one of the frictional elements and engaging the other of the frictional elements and a continuously variable transmission section that establishes a desired speed continuously. The control system makes a speed change control of the continuously variable transmission section cooperate with a change of an input rotation speed of the stepwise variable transmission section. The control system is configured to carry out during the shift change of the stepwise variable transmission section, judging whether a delivery of a torque from a disengaging side frictional element to an engaging side frictional element is completed or not; and starting the speed change control of the continuously variable transmission section upon judgment of the completion of the delivery of the torque regarding that an inertial phase has started.
