Abstract
In an apparatus for controlling a continuously variable transmission, a transmission ratio, an input shaft rotational speed and an input torque, etc., are detected, an axial thrusts of the drive and driven pulleys are detected therefrom, an inter-shaft force is detected, a friction coefficient of the driven pulley including at least a radial component of the friction coefficient μRDN is calculated in accordance with predetermined relational equations, a target axial thrust of the driven pulley is calculated based on at least the friction coefficient and the axial thrust of the driven pulley is controlled based on the calculated target axial thrust.
