The present disclosure provides a system and method for learning driveline disconnect clutch lift-off. Systems and methods for operating a driveline disconnect clutch of a hybrid vehicle are presented. In one example, when a driveline disconnect clutch is de-stroke, driveline disconnect clutch up-off pressure is estimated as a function of a derivative of driveline disconnect clutch pressure. The driveline disconnect clutch is pre-positioned based on an estimated driveline disconnect clutch lift-off pressure upon anticipation of driveline disconnect clutch closure.

    本公开提供“用于获知传动系分离离合器升离的系统和方法”。呈现了用于操作混合动力车辆的传动系分离离合器的系统和方法。在一个示例中,当传动系分离离合器去冲程时,根据传动系分离离合器压力的导数来估计传动系分离离合器升离压力。在预期到传动系分离离合器闭合后基于估计的传动系分离离合器升离压力来预先定位传动系分离离合器。
