摘要： An object of the present invention is to enhance precision of air-fuel ratio control after return from fuel cut in a control device for an internal combustion engine that has a plurality of fuel injection modes, and performs calculation of a fuel injection amount by a method corresponding to an injection mode in use. For this object, the control device for an internal combustion engine the present invention provides normally determines the injection mode in response to an operation state, but designates a specific injection mode with a higher priority than the injection mode determined in response to the operation state at a time of return from fuel cut. For a predetermined time period after the return from fuel cut, the control device prohibits the injection mode from being changed in response to the operation state, and keeps fuel injection according to the designated specific injection mode.

摘要： A convergence determination of intake valve phase control is made by comparing a phase deviation of an intake valve from a target phase with a convergence determination value. At the time of convergence, it is determined that the intake valve phase has reached the target phase, so that the required phase-change amount of a camshaft is set to zero and therefore the actuator operation amount is also set to zero. At the time of engine stop when the target phase has a fixed value, after convergence of the intake valve phase control, the operation of the actuator is stopped. In addition, during the course of engine stop, the convergence determination value is set to be switched from the time of engine operation so that the convergence determination of the intake valve phase control is made in more relaxed conditions compared with at the time of engine operation.

摘要： At the time of reference position learning for ensuring accuracy in detecting a valve timing, an operation amount of an actuator is set such that intake valve phase changes to a position of most retarded angle as a reference phase. When the intake valve phase reaches the most retarded angle and the change in the intake valve phase stops (YES at S150), it is determined that the intake valve phase has reached the reference phase and the learning is terminated normally. If the learning operation does not end normally even after the time lapse from the start of learning exceeds a limit time Tlmt, the reference position learning is terminated forcibly (YES at S170), and power supply to the actuator is stopped. Thus, power consumption can be reduced and the apparatus can be protected at the time of reference position learning.
摘要翻译：在确定气门正时检测精度时的基准位置学习时，将致动器的操作量设定为使得进气门相位变为大部分滞后角位置作为基准相位。当进气阀相达到最大延迟角并且进气阀相位的变化停止时（S150为“是”），判断为进气阀相位已达到基准相位，并且学习正常结束。即使在从学习开始的时间经过超过限制时间T1mt之后，即使学习动作不能正常结束，参考位置学习被强制终止（S170为“是”），停止向致动器供电。因此，可以减少功耗，并且可以在参考位置学习时保护装置。

摘要： An ECU executes a program including the steps of: controlling, when the phase of an intake valve is a phase advanced relative to a threshold value CA (FF) (NO in S106), an electric motor operating an intake VVT mechanism by feedback control (S202); and controlling, when the phase of the intake valve is a phase retarded relative to the threshold value CA (FF) (YES in S106), the electric motor by feed-forward control (S200). Under the feed-forward control, a duty command value is output that is smaller than an upper limit of a duty command value under the feedback control.
