PROBLEM TO BE SOLVED: To provide a controller of a continuously variable transmission capable of protecting a belt type continuously variable transmission from input of excessive torque.SOLUTION: A controller of a transmission is configured to: set limit torque according to a state of a torque converter (S1); when engine torque exceeds the limit torque (S2: YES), output an operation request for torque limit control (S3), operate the torque limit control, and then limit the engine torque to the limit torque set according to the state of the torque converter; when failure of a throttle valve occurs, the torque limit control operates incorrectly, and the engine torque exceeds an added value of the limit torque and a predetermined value (S4: NO), pulling up a clamping maximum guard provided in clamping control by a predetermined value (S5).SELECTED DRAWING: Figure 3

    【課題】過大なトルクの入力からベルト式の無段変速機を保護できる、無段変速機の制御装置を提供する。【解決手段】トルクコンバータの状態に応じた制限トルクが設定される(S1)。エンジントルクが制限トルクを超えるときには(S2:YES)、トルク制限制御の作動要求が出力されて(S3)、トルク制限制御が作動し、エンジントルクがトルクコンバータの状態に応じて設定された制限トルク以下に制限される。スロットルバルブの故障などが発生し、トルク制限制御が正常に作動しておらず、エンジントルクが制限トルクと所定値との加算値を超えている場合(S4:NO)、挟圧制御に設けられている挟圧最大ガードが所定値だけ引き上げられる(S5)。【選択図】図3
