Abstract

A vehicle includes an engine as a drive source and a continuously variable transmission. The continuously variable transmission includes a torque converter having a lockup clutch. When simultaneous execution of an upshift of the continuously variable transmission and a lockup engagement of the lockup clutch is required in accordance with an accelerator depression operation, the LU engagement control of the lockup clutch is started in accordance with an LU engagement request. On the other hand, the upshift control uses the continuously variable transmission to place the starting of the control with respect to the upshift request on standby and cancels the standby when the LU engagement control of the lockup clutch enters a lockup engagement completion region and starts the upshift control (delayed control).
