CONTROL DEVICE OF CONTINUOUSLY VARIABLE TRANSMISSION

PROBLEM TO BE SOLVED: To provide a control device of a continuously variable transmission capable of generating engine brake desired by a driver according to a running state in downhill running.SOLUTION: A control device 1 of a continuously variable transmission includes running state acquiring means 10a for acquiring a running state in downhill running, downhill transmission gear ratio control portion 10b for controlling gear shift to a transmission gear ratio at a low speed side on the basis of a target deceleration in downhill running, an engine brake shortage determination portion 10c for determining whether engine brake is insufficient or not, engine brake excessiveness determination means 10d for determining whether the engine brake is excessive or not, and a learning portion 10e for setting a learning value of a target deceleration larger than a target deceleration used in controlling the downhill transmission gear ratio when the shortage is determined, and setting a learning value of a target deceleration smaller than the target deceleration used in controlling the downhill transmission gear ratio when the excessiveness is determined, and the learning portion 10e sets the learning value of the target deceleration in every running state.SELECTED DRAWING: Figure 1 【課題】降坂路走行中の走行状況に応じた運転者の好みのエンジンブレーキを発生させることを可能とした無段変速機の制御装置を提供する。【解決手段】無段変速機の制御装置１は、降坂路走行時の走行状況を取得する走行状況取得手段１０ａと、降坂路走行時に目標減速度に基づいて低速側の変速比に変速制御する降坂変速比制御部１０ｂと、エンジンブレーキが不足か否かを判定するエンジンブレーキ不足判定部１０ｃと、エンジンブレーキが過剰か否かを判定するエンジンブレーキ過剰判定手段１０ｄと、不足と判定した場合には降坂変速比制御で使用している目標減速度よりも大きい目標減速度の学習値を設定し、過剰と判定した場合には降坂変速比制御で使用している目標減速度よりも小さい目標減速度の学習値を設定する学習部１０ｅとを備え、学習部１０ｅは走行状況毎に目標減速度の学習値を設定する。【選択図】 図１
