More Information
Summary:A control device for a continuously variable transmission mechanism of a vehicle includes: a stepwise variable transmission mechanism which is disposed in series with the continuously variable transmission mechanism, and which has at least two or more forward gear stages; and a controller configured to increase the belt capacities to be greater than the belt capacity set when an accelerator opening degree is zero, at least in a time period from a timing when the accelerator opening degree becomes zero, to a timing when a braking force is generated by a depression of a brake pedal, the controller being configured to set an increase amount with respect to the belt capacity set when the accelerator opening degree is zero, to a smaller value as a transmission gear ratio of the stepwise variable transmission mechanism is higher.
