More Information
Summary:In the present invention, there are provided with an auxiliary transmission mechanism (30) disposed in series with a variator (20), and having at least two or more forward gear stages; and a transmission controller 12 configured to increase the belt capacities to be greater than the belt capacity set when the accelerator opening degree (APO) is zero, at least in a time period from a timing when the accelerator opening degree APO becomes zero, to a timing when a braking force is generated by a depression of a brake pedal. The transmission controller (12) is configured to set an increase amount with respect to the belt capacity set when the accelerator opening degree (APO) is zero, to a smaller value as a transmission gear ratio of the auxiliary transmission mechanism (30) is higher.
