    摘要： [Summary] A control device for a lock-up-clutch (20) installed in a torque converter (2) arranged between a prime mover (1) serving as a driving source and an automatic transmission mechanism (4) is described, the control device including an engagement control means (8H) that carries out a calculation to increase an engaging capacity of the lock-up-clutch (20) with the passage of time during an engagement control time in which the torque converter (2) is shifted from a converter condition to a lock-up condition, the prime mover (1) driving an auxiliary device (110), in which when, during the control to increase the engaging capacity of the lock-up-clutch (20), an input torque inputted to the torque converter from the prime mover (1) is increased due to reduction in load of the auxiliary device (110), the engagement control means (8H) promotes the increase of the engaging capacity of the lock-up-clutch (20) based on the amount of increase of the input torque. According to the control device for the lock-up-clutch of the present invention, the pressure shortage that would be induced in the period toward the lock-up condition is assuredly eliminated.

    摘要： When a torque converter (2) is being switched from a slip engagement state to a full engagement state as a result of an ON operation of an accelerator, during the execution of control that achieves the full engagement state after increasing the rotation of an internal combustion engine (1) in the slip engagement state while expanding the torque transmission capacity of a lockup clutch (20) by means of slip engagement, if it is determined that there has been a gain in the output torque of the internal combustion engine (1) when, within a prescribed period of time after the beginning of the control, the detected input/output differential rotation speed of the lockup clutch (20) is at or below a second prescribed value (”N2) that is smaller than a first prescribed value (”N1) after having increased to or above the first prescribed value, a prescribed capacity is added to the expanding torque transmission capacity of the lockup clutch (20). It is possible to avoid judder variation caused by the release of an accelerator pedal during a transition to a lockup state.

    摘要： When a torque converter (2) is being returned to a full engagement state as a result of an ON operation of an accelerator after temporary disengagement of the full engagement state, during the execution of control that achieves the full engagement state after increasing the rotation of an internal combustion engine (1) by means of slip engagement while expanding the torque transmission capacity of a lockup clutch (20), if it is determined that there has been a gain in the output torque of the internal combustion engine (1) when, within a prescribed period of time after the beginning of the control, the detected input/output differential rotation speed of the lockup clutch (20) is at or below a second prescribed value (”N2) that is smaller than a first prescribed value (”N1) after having increased to or above the first prescribed value, a prescribed capacity is added to the expanding torque transmission capacity of the lockup clutch (20).

    摘要： The present invention reduces the occurrence of a shock when depressing and operating the accelerator from a state of coasting. An engine-equipped vehicle provided with a torque converter (4) comprising a lock-up clutch (3) between the engine (1) and a continuously variable transmission (6), the engine-equipped vehicle being further provided with a fuel cutoff control unit (11 a) and a CVT control unit (12). The fuel cutoff control unit (11 a) prevents fuel injection to the engine (1) while in a coasting state with the driver's foot away from the accelerator, and restarts the fuel injection on the basis of a fuel recovery permission. The CVT control unit (12) carries out a cooperative control of a lock-up release control for reducing the clutch engagement capacity of the lock-up clutch (3) and a transmission control for shifting the transmission. Then, if there is an accelerator depression operation while coasting with the lock-up clutch (3) in an engaged state, the lock-up release timing and the shift timing are offset from one another.
