摘要： A variable valve timing control device includes a valve unit including a spool having a plurality of land portions at an outer circumference of the spool, and being formed with a drain flow path inside the spool. The valve unit allows a second pump port and a lock port to communicate with each other in a case where the spool is set at an unlock position where a lock state of a lock mechanism is released, and the valve unit closes the second pump port with the land portion of the spool and allows the lock port to communicate with the drain flow path in a case where the spool is set at a lock position where the lock mechanism is allowed to be shifted in the lock state.

摘要： A valve opening/closing timing control device is configured to be capable of appropriately setting a valve opening/closing timing within a short period of time from start-up of an internal combustion engine. An advancing chamber and a retarding chamber for relative phase control are formed between a driving rotating body that rotates synchronously with a drive shaft of an internal combustion engine and a driven rotating body that rotates integrally with a valve opening/closing camshaft, and a lock mechanism that locks the relative rotation phase at a locked phase is provided. During start-up of the internal combustion engine, a controller starts fluid-filling control for filling the advancing chamber and the retarding chamber with a fluid, and performs unlock control for releasing a locked state of the lock mechanism before filling of the fluid by the fluid-filling control is completed.

摘要： A control device is configured that can shorten the time required for a system to stop due to an ignition switch operation in a situation in which the internal combustion engine is stopped due to stop control. The control device includes a control unit that, in the situation in which the internal combustion engine is stopped due to stop control, if the transmission mechanism is operated to a second shift position that is different from a first shift position in which the vehicle can travel, executes phase conversion control to shift a valve opening/closing timing control mechanism from a first lock phase to a second lock phase.

摘要： A valve opening and closing timing control apparatus includes a drive-side rotational body, a driven-side rotational body, an intermediate lock mechanism which selectively switches between a lock state where displacement of a relative rotational phase of the driven-side rotational body relative to the drive-side rotational body is restrained in an intermediate lock phase and an unlock state where the lock state is released, and an electromagnetic valve. At a time of predetermined operation of an internal combustion engine, a value of the drive current is set as a boundary current, and the value of the drive current to be set as the boundary current differs, by a predetermined value, from a value of the drive current at a time when the unlock state was switched to the lock state due to the change of the drive current.

When working fluid is discharged from the intermediate lock mechanism, and working fluid is supplied to the advancing chamber and is discharged from the retarding chamber, the maximum working fluid flow amount through the advancing and retarding channels is greater than the maximum working fluid flow amount through the advancing and retarding channels when the electromagnetic valve is controlled such that the working fluid is supplied to the intermediate lock mechanism.
