A control unit comprises determining unit for determining whether or not a predetermined elapsed time condition is established after a shift has been performed to a specific gear position reached by engaging a specific frictional engagement element of a stepped transmission mechanism, and restricting unit for prohibiting the stepped transmission mechanism from performing a shift back to the specific gear position while allowing a continuously variable transmission mechanism to perform shifts so that an automatic transmission is controlled to a target speed ratio until the determining unit determines that the predetermined elapsed time condition is established. |
