摘要： In a control apparatus and a control method for a variable mechanism, when a predetermined condition is fulfilled, a movable member (3) is driven until an engagement portion (31) contacts one restriction member (22), and the absolute position of the movable member (3) when it is determined that displacement of the movable member (3) is stopped is learned, as a reference position. When supply of electric power is stopped, the absolute position of the movable member (3) is learned as an initial reference position. When electric power is supplied, the movable member (3) is driven from the initial reference position until the engagement portion (31) contacts the one restriction member (22), and a one-side displacement amount is calculated. If the one-side displacement amount is smaller than a one-side distance, it is determined that a foreign substance is caught in an area on a side of a site corresponding to the one restriction member (22) in a movable range.

摘要： A variable valve timing apparatus for an internal combustion engine, including: an actuator that activates a variable valve timing mechanism; a detection unit that detects a driving position of the actuator; a control unit that drive-controls the actuator, and when a predetermined execution condition is established, executes one of a first initialization process and a second initialization process that match the driving position of the actuator detected by the detection unit with an actual driving position of the actuator; and an abnormality determination unit that determines whether or not an abnormality is present in the driving position detected by the detection unit and stores an abnormality history after determining that an abnormality is present. The control unit executes the first initialization process when the abnormality history is stored and the second initialization process when the abnormality history is not stored.
