To provide a control device of a continuously variable transmission which can improve the usability of a user while securing the safety of the user.SOLUTION: A control device of a continuously variable transmission controls the continuously variable transmission having a hydraulic pressure supply part which is filled with a working fluid, and a stepless gear change part which can perform a stepless gear change using hydraulic pressure in the hydraulic pressure supply part, and comprises a gear change control part and a detection part. The gear change control part has a setting part for setting a target gear change ratio of the stepless gear change part on the basis of the operation information of a vehicle which is mounted with the stepless gear change part, and performs gear change control so as to make a gear change ratio of the stepless gear change part approximate the target gear change ratio by controlling the hydraulic pressure in the hydraulic pressure supply part. The detection part detects an abnormality which is affected to the setting of the target gear change ratio by the setting part. When the detection part detects the abnormality, the gear change control part makes the hydraulic pressure in the hydraulic pressure supply part transit to a range which is not smaller than a first value at which an operation of the stepless gear change part at a minimum limit becomes possible, and smaller than a second value at a normal operation before the detection part detects the abnormality.SELECTED DRAWING: Figure 1
【課題】ユーザの安全を確保しつつ、ユーザの利便性を向上させることが可能な無段変速機の制御装置を提供する。【解決手段】本開示の無段変速機の制御装置は、作動油が充填された油圧供給部と、その油圧供給部における油圧を利用した無段階変速が可能な無段変速部とを有する無段変速機の制御を行うものであって、変速制御部と検出部とを備える。変速制御部は、無段変速部が搭載される車両の運転情報に基づき無段変速部の目標変速比を設定する設定部を有し、油圧供給部における油圧の制御により無段変速部における変速比を目標変速比に近づけるように変速制御を行う。検出部は、設定部による目標変速比の設定に影響する異常を検出する。変速制御部は、検出部が異常を検出した場合、油圧供給部における油圧を、無段変速部の最低限度の動作が可能となる第1の値以上であって検出部が異常を検出する前の通常動作時における第2の値よりも低い範囲に移行させる。【選択図】図1
