摘要： After power supply from a backup power source to a volatile memory is restored from temporary suspension, a remaining data determining section determines whether data of change history remaining in the volatile memory is data that has been stored immediately before the suspension of the power supply. When it is determined that the data remaining in the volatile memory is not the data that has been stored immediately before suspension of the power supply, a reference value learning section moves an actuator to a limit position, assigns the reference value to an initial value, and clears the change history. When suspension of the power supply from the backup power source reoccurs before completion of the reference value learning by the reference value learning section, a control section invalidates the determination of the remaining data determining section and performs the reference value learning, after the power supply is restored.

摘要： When it is determined that an engine speed NE rapidly decreases (positive outcome at S210), a throttle increase amount TAu and a valve lift increase amount VLu are computed based on a decrease rate NEd of the engine speed NE (S220). Then, a target throttle opening degree TAt of a throttle valve and a target maximum valve lift VLt of an intake valve are increased by using the throttle increase amount TAu and the valve lift increase amount VLu (S230). As a result, a drop in the engine speed during idling is reliably suppressed.

摘要： An electronic control unit (60) performs maximum position learning by driving an actuator (50) to move a control shaft (340), and learning the position where stopping occurs because the cylinder head (20) contacts with the Hi end stopper (343) as the movable limit position (Hi end) where the maximum lift amount of the intake valve is largest, to correct the cumulative movement of the control shaft (340). The electronic control unit (60) prevents maximum position learning when the engine speed NE is higher Than a prescribed rotational speed NEst.

摘要： A brushless motor of a variable valve mechanism varies a actuation parameter of an intake valve of an engine. A position sensor outputs a pulse signal when the brushless motor rotates. A position counter calculates a counter value by counting edges of the pulse signal. A motor control device obtains a detection value of a motor rotational angle based on the counter value when the motor control device is in a powered state. An engine control device determines that the detection value of the motor rotational angle is displaced from the actual value when the engine control device detects that the engine is operating and the motor control device portion is in a non-powered state.

摘要： When the engine load is in a high-load zone, an absolute value control is executed, wherein the actual values of valve timings of an intake valve and an exhaust valve and a valve duration of the intake valve are controlled to coincide with respective target values set based on the operating state of an internal combustion engine. When the engine load is in a low-load zone, a relative value control is executed, wherein an actual value of a valve overlap amount of the intake valve and the exhaust valve is controlled to coincide with a target valve overlap amount obtained based on the target values. Therefore, a control method for the internal combustion engine that is appropriate for the operating state of the engine when the operating state of the engine is in transition is obtained.

摘要： An electronic control unit executes a delay control and a load compensation control. In the delay control, the period from when an engine stop request for an engine is made to when the engine is actually stopped is extended. In the load compensation control, the engine power is adjusted according to the driving load of auxiliary devices. Further, if the engine stop request is made during operation of a compressor, which is one of the auxiliary devices, the electronic control unit executes a power reduction control, in which ignition timing is retarded to temporarily reduce the engine power. As a result, in an internal combustion engine that executes the delay control, sudden increases in the engine speed that are likely to occur when an engine stop request is made during operation of auxiliary devices are reliably suppressed.
