ABSTRACT:
The amount of engagement of a direct couping mechanism such as lockup clutch (6) disposed between input and output members of a hydrodynamic driving apparatus such as a torque converter (5) to mechanically connect or disconnect the input and output members (5a, 5b) is controlled so as to bring a parameter indicative of the amount of slippage between the input and output members into a predetermined reference range. The average value of the parameter which is measured in a prescribed time interval is determined, and a control value for the amount of engagement in a next prescribed time interval is determined based on the differnece between the average value and the predetermined reference range value.
