Zusammenfassung: | A continuously variable transmission, a control system, and a method is provided for synchronizing a clutch application state change and a continuous upshift in a motor vehicle propulsion system having a continuously variable transmission (CVT). The control system and method are configured to determine whether a continuous upshift of the CVT is impending. The continuous upshift is defined as a pulley ratio change exceeding a predetermined threshold for a predetermined pulley ratio change period. If a continuous upshift is impending, the control system and method are configured to alter a clutch engagement state after a predetermined delay period to synchronize the change in clutch engagement state with an engine speed change.
种用于在具有无级变速器(CVT)的机动车辆推进系统中使离合器施加状态变化与连续升档同步的无级变速器、控制系统以及方法。该控制系统和方法配置为确定CVT的连续升档是否即将发生。该连续升档被定义为对于预定带轮比变化周期带轮比变化超过预定阈值。如果连续升档即将发生,则该控制系统和方法配置为在预定延迟周期之后改变离合器接合状态,以使该离合器接合状态的变化与发动机转速变化同步。 |
