Method of learning an initial capacity point of a clutch in a dual clutch transmission
Abstract:
A method of learning an initial capacity point of a clutch in a dual clutch transmission includes identifying when the dual clutch transmission is operating in a steady state gear condition with a first clutch continuously transmitting torque to a first shaft. When the dual clutch transmission is operating in a steady state gear condition, a second clutch is sequentially positioned in each of a plurality of application positions (Pn, Pn+1, Pn+2, . . . , Pn+i). The second clutch is configured to transmit torque to a second shaft. The second shaft is positioned in a geared state in each of the plurality of application positions. The first application position (Pn+i) in the sequence of application positions in which the second shaft is not successfully positioned in the geared state is defined as the initial capacity point of the second clutch.
