Abstract
A control system of an automatic transmission including a stepwise variable transmission section and a continuously variable transmission section 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 and is configured to judge, during the shift change of the stepwise variable transmission section, whether a delivery of a torque from one of a plurality of disengaging side frictional elements to one of a plurality of engaging side frictional elements is completed, and to start the speed change control of the continuously variable transmission section upon judgment that the delivery of the torque is completed and that an inertial phase has started.
