摘要： PURPOSE: To prevent a lockup clutch from wearing in an early stage by providing an adjusting means adjusting connecting force between an engine output shaft and a turbine output shaft so as to be in the fixed slip condition, and prohibiting adjustment of the connecting force in the case of speed ratio of a torque converter being over a fixed value. CONSTITUTION: A torque converter additionally provided in an automatic transmission is provided with a lockup clutch, and the lockup clutch is controlled to be one of a relased condition, a perfectly connected condition, or a fixed slipping condition, by controlling supplied working pressure with a duty solenoid valve 123. In this case, signals of a vehicle speed sensor 301, an engine speed sensor 303, a turbine speed sensor 305, and the like are input to a controller 300, and hence the speed change ratio of the torque converter is obtained. When speed change ratio is larger than a fixed value, connecting force adjustment making the lockup clutch to be in the slipping condition is prohibited, and the lockup clutch is changed to the released condition or the perfectly connected condition.
