Abstract:
1. A control device of a continuously variable transmission for a vehicle, comprising: a continuously variable transmission mechanism capable of continuously changing a speed ratio; a sub-transmission mechanism provided in series with the continuously variable transmission, including a first gear position and a second gear position having a smaller speed ratio than a speed ratio of the first gear position as forward gear positions and adapted to switch between the first gear position and the second gear position by selectively engaging or releasing a plurality of frictional engagement elements; a transmission control unit configured to switch the gear position of the sub-transmission mechanism to the first gear position after the vehicle is stopped with the gear position of the sub-transmission mechanism kept in the second gear position; and a during-stop target torque capacity setting unit configured to set a target torque capacity of an engagement-side frictional engagement element, which needs to be engaged for switching the gear position of the sub-transmission mechanism to the first gear position, out of the plurality of frictional engagement elements at a startup torque capacity larger than an input torque input to the sub-transmission mechanism while the vehicle is stopped when the gear position of the sub-transmission mechanism is switched from the second gear position to the first gear position while the vehicle is stopped.
