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 (ΔN2) that is smaller than a first prescribed value (ΔN1) 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： 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.

摘要： In the present invention, an engine controller (35) of an internal combustion engine (1) executes fuel cut when the accelerator opening degree has reached 0 during travel by a vehicle, and applies an antiphase torque by fuel supply for some cylinders so as to cancel out vibration in the vehicle front/rear direction due to torsional vibration of a drive system associated with the fuel cut. The timing for applying the antiphase torque is made to be later than ordinarily if the internal combustion engine (1) has a torque greater than an ordinary torque immediately prior to fuel cut for forced regeneration of a GPF (18). A cylinder that has an ignition time close to a timing that is later by 1/4 of a cycle of torsional vibration, where the origin of vibration is a timing where the torque of a drive shaft inverted from positive to negative, is selected as being a combustion cylinder.
