摘要： PROBLEM TO BE SOLVED: To provide a controller for an internal combustion engine capable of calculating target throttle opening accurately.
SOLUTION: A target engine load rate KLT is calculated. Target throttle opening θtT required for changing an actual engine load rate into the target engine load rate KLT is calculated based on pressure in an intake pipe being pressure in an intake passage on the downstream side of a throttle valve. Whether the target throttle opening θtT can be realized by a step motor or not is determined. When it is determined that the target throttle opening θtT cannot be realized, the maximum or minimum throttle opening capable of being realized by the step motor is set to the final target throttle opening θtTf. The step motor drives the throttle valve so that actual throttle opening coincides with the final target throttle opening θtTf. Pressure Pm in the intake pipe is inferred based on the final target throttle opening θtTf.

摘要翻译：要解决的问题：提供能够精确地计算目标节气门开度的内燃机的控制器。
解决方案：计算目标发动机负载率KLT。基于作为节流阀下游侧的进气通路中的压力的进气管的压力，计算将实际发动机负荷率变更为目标发动机负荷率KLT所需的目标节气门开度θtT。确定目标节气门开度θtT是否可以通过步进电机来实现。当确定不能实现目标节气门开度θtT时，能够通过步进电动机实现的最大或最小节气门开度被设定为最终目标节气门开度θtTf。步进电机驱动节流阀，使得实际的节气门开度与最终目标节气门开度θtTf重合。基于最终目标节气门开度θtTf推断进气管中的压力Pm。版权所有（C）2006，JPO＆NCIPI

摘要： PROBLEM TO BE SOLVED: To provide a control device and a control method for effectively re-entering an engine into an exhaust gas recirculation mode. SOLUTION: The control device of the internal combustion engine (engine) on which the exhaust gas recirculation system is mounted predicts at least one of an intake manifold temperature in the EGR (exhaust gas recirculation) mode and an intake manifold pressure in the EGR mode or desirably both of them in the boost mode operation. When an intake manifold critical temperature in the EGR at which condensation occurs is calculated, these predictions are used. Next, the control device compares the predicted temperature value with a calculated intake manifold critical temperature, when the predicted temperature is larger than the calculated temperature, the control device instructs a re-entry into the EGR mode.

摘要： PROBLEM TO BE SOLVED: To enable the relatively accurate estimation of the intake air quantity even after the computed intake pipe pressure is guarded by the atmospheric air pressure in regard to an intake air quantity estimating device for an internal combustion engine for computing the intake pipe pressure on the downstream side of a throttle valve to use it to estimate the intake air quantity.
SOLUTION: An intake pipe pressure computing means computes the actual intake pipe pressure by using the intake pipe pressure computed last time and the throttle valve passing air quantity computed last time by a throttle valve passing air quantity computing means (step 107). This intake pipe pressure computing means is provided with a guard means for replacing the actual intake pipe pressure with the atmospheric air pressure when the actual intake pipe pressure computed by the intake pipe pressure computing means is higher than the atmospheric air pressure (step 103), and a correcting means for correcting the throttle valve passing air quantity computed last time based on a differential pressure between the atmospheric air pressure and the intake pipe pressure computed last time when the actual intake pipe pressure is replaced with the atmospheric air pressure by the guard means (step 104).
