PROBLEM TO BE SOLVED: To suppress a restart time lag from termination of engine stop control to engagement of start clutch.SOLUTION: A control device of a continuously variable transmission with an auxiliary transmission, is provided with: a low brake solenoid valve 113 disposed on the way of an oil passage from a mechanical oil pump 10 to a low brake 32, for controlling an oil pressure to the low brake 32; and a transmission controller 12 outputting a clutch oil pressure indication value PL/Bto the low brake solenoid valve 113. The transmission controller 12 outputs the clutch oil pressure indiction value PL/Bto the low brake solenoid valve 113 for opening an oil passage from the mechanical oil pump 10 to the low brake 32 in advance at least before an engine speed rises by restarting of an engine. 【課題】エンジン停止制御終了から発進クラッチ締結までの再発進タイムラグを小さく抑えること。【解決手段】副変速機付き無段変速機の制御装置において、メカオイルポンプ１０からローブレーキ３２への油路途中位置に設けられ、ローブレーキ３２への油圧を制御するローブレーキソレノイドバルブ１１３と、ローブレーキソレノイドバルブ１１３へのクラッチ油圧指示値ＰL/B*を出力する変速機コントローラ１２と、を設ける。変速機コントローラ１２は、コーストストップ制御/アイドルストップ制御が行われたとき、少なくともエンジン再始動によりエンジン回転数が立ち上がる前に、メカオイルポンプ１０からローブレーキ３２への油路を予め開いておくクラッチ油圧指示値ＰL/B*をローブレーキソレノイドバルブ１１３に出力する。【選択図】図８
