Abstract
A continuously variable transmission control system includes a continuously variable transmission device having an electricity-driven actuator that changes an width between a moveable sheave and a fixed sheave in at least one pulley of a drive pulley and a driven pulley, and a control device that controls driving of the electricity-driven actuator. The control device selects, from a plurality of speed relationships, each of which is a relationship between an input shaft rotational speed of the drive pulley and an output shaft rotational speed of the driven pulley, one speed relationship according to an input of a switch command signal or a drive state of the vehicle, and changes the width between the moveable sheave and the fixed sheave based on the selected speed relationship and detected values of the input shaft rotational speed and the output shaft rotational speed.
