摘要：
A control apparatus for an automatic transmission system having a serial arrangement of a stepwise variable automatic transmission mechanism and a continuously variable automatic transmission mechanism, the control apparatus being disposed in the automatic transmission system and performing a shift control of the continuously variable automatic transmission mechanism in accordance with variation in transmission ratio of the stepwise variable automatic transmission mechanism, the control apparatus including a control section configured to execute a retardation processing upon shift control of one of the continuously variable transmission mechanism and the stepwise variable transmission mechanism which has a smaller response delay of an actual transmission ratio from a target transmission ratio than that of the other transmission mechanism.
