More Information
Summary:A valve open-close timing control device includes a driving rotator, a driven rotator, a phase adjusting mechanism, a sensor unit, a storage configured to store the plurality of divided regions consecutively provided, as a plurality of divided length information pieces corresponding to divided lengths of the divided regions, and an actual phase acquisition unit configured to start acquisition of the crank angle signal and the cam angle signal along with start of actuation control of actuating the internal combustion engine, specify one of the divided regions by referring to the divided length information pieces stored in the storage in accordance with the crank angle signal at timing set in accordance with the cam angle signal, and acquire the relative rotation phase as an actual phase in accordance with the crank angle signal corresponding to the boundary of the divided region thus specified and the reference crank angle signal.
