Document Type and Number:
WIPO Patent Application WO/2012/144023
Kind Code:
A1
Abstract:
Provided is a control device for a belt-type continuously variable transmission, the control device being capable of suppressing a deterioration in fuel consumption.
Compared to the friction coefficient (μ1) of an inside portion in the radial direction of each tapered surface of a driven pulley (7), the friction coefficient (μ2) of an outside portion is formed smaller, and the present invention is provided with a gear change range setting means for increasing the frequency of changing the change gear ratio using the inside portion when a gear change control mode for improving energy consumption efficiency is selected.
