Abstract (en)
[origin: WO2010046203A1] In the proposed method for engaging the torque converter lock-up clutch in a power transmission of a mobile machine, the available engine moment or turbine moment is determined prior to shifting the lock-up clutch, and the gradient of the engine moment is controlled during the shifting process and, optionally, for a defined period of time following the shifting process by means of the transmission controller in such a way that an acceleration of the vehicle and thus a jerk is reduced or prevented during the shifting process.
