To provide a continuously variable transmission capable of reducing discomfort that may be felt by a driver.SOLUTION: A continuously variable transmission (CVT) 1 is provided between an engine 5 and a drive wheel, and determines a pulley ratio so that a vehicle speed becomes a target vehicle speed by referring to a road load shift line in which a target engine speed depending on the target vehicle speed is set in an auto cruise mode of keeping the vehicle speed at the target vehicle speed. When a driver updates the target vehicle speed, the CVT switches a shift characteristic referred to upon determining the pulley ratio to a shift line (shift characteristic for target vehicle speed update) having a characteristic that the target engine speed with respect to the same target vehicle speed becomes higher than the road load shift line.SELECTED DRAWING: Figure 1
【課題】 ドライバに与える違和感を低減できる無段変速機を提供する。【解決手段】 エンジン5および駆動輪間に設けられ、車速を目標車速に保つオートクルーズモード時、目標車速に応じた目標エンジン回転速度が設定されたロードロード変速線を参照し、車速が目標車速となるようにプーリ比を決定するCVT1であって、ドライバが目標車速を更新した場合、プーリ比を決定する際に参照する変速特性を、同一の目標車速に対する目標エンジン回転速度が、ロードロード変速線よりも高くなる特性を有する変速線（目標車速更新時用変速特性）に切り替える。【選択図】 図１
