Abstract

Methods and systems are provided for adapting a pressure to torque transfer function of a clutch of a dual clutch transmission. In one example, a method includes operating a first clutch of the dual clutch transmission at a selected capacity to change a speed of a first transmission input shaft to a desired speed, adjusting values of a torque transfer function of the first clutch based on a rate of the speed change, and maintaining driver demanded wheel torque during the adjusting via controlling torque output of an electric motor positioned in the driveline. In this way, the method may be used to adapt both positive and negative torque transfer functions.
