Abstract
A continuously variable transmission () has a torque convertor () having a lock-up clutch () and a continuously variable transmission mechanism (). A control unit () has a shift control unit (C) configured to be able to perform a pseudo stepwise up-shift control that varies a transmission ratio of the continuously variable transmission mechanism () stepwise, a lock-up control unit (A) configured to control an engagement state of the lock-up clutch (), and a torque control command unit (D) configured to perform a torque-down control of a driving source (). When the engagement control of the lock-up clutch () and the pseudo stepwise up-shift control are performed at the same time, the torque control command unit (D) configured to perform the torque-down control with a greater torque reduction amount.
