摘要： In feedback control of a discharge amount of a high pressure fuel pump in which an actual fuel pressure is caused to become a target fuel pressure, when a deviation between the target fuel pressure and the actual fuel pressure has transiently changed, updating of an integral term of the feedback control is stopped. As a result, needless updating of the integral term when the deviation of the target fuel pressure and the actual fuel pressure has transiently increased is inhibited, and fuel pressure overshoot is reliably suppressed.

摘要： In valve timing control after issuance of an engine stop instruction with a prescribed value set as a target phase, an ECU delays permission of an engine stop process within a prescribed time period while an intake valve phase has not yet reached the target value, so that a valve timing control operation is continued while the engine operation is continued in an idle state. After the lapse of a prescribed time period from the issuance of the engine stop instruction, however, the ECU permits the engine stop process no matter whether the intake valve phase has reached the target value or not. As a result, the amount of valve timing that can be changed by the valve timing control in the engine stop operation can be increased, without causing any uncomfortable feeling of the driver.
摘要翻译：在以规定值设定为目标相位的发动机停止指示发出后的气门正时控制中，在进气门相尚未达到目标值的情况下，ECU在规定时间内延迟发动机停止处理的许可，在空转状态下继续发动机运转时继续进行气门正时控制动作。然而，在从发动机停止指令发出规定的时间段之后，ECU不管进气阀相位是否达到目标值，都允许发动机停止。结果，可以增加可以通过发动机停止操作中的气门正时控制而改变的气门正时的量，而不会引起驾驶员的任何不适感。

摘要： An ECU varies a period during which an intake valve and an exhaust valve are both simultaneously open by setting a target overlap angle OVP to be equal to a limit overlap angle OVL until the coolant temperature becomes higher than a reference temperature to reduce the internal EGR amount. This prevents combustion deterioration in a gasoline engine.

摘要： A control device for an internal combustion engine includes an intake-side variable valve timing mechanism and a controller. The intake-side variable valve timing mechanism is configured to continuously advance or retard a phase of a cam that actuates an intake valve. The controller is configured to actuate the intake-side variable valve timing mechanism toward a retardation side and position the intake-side variable valve timing mechanism at a prescribed position, and execute fail-safe control on the basis of a signal from a cam position sensor instead of a signal from the crank position sensor, when it is determined that there is a failure in a crank position sensor of the internal combustion engine.
