Title:
VALVE TIMING CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/018329
Kind Code:
A1
Abstract:
In the present invention, a determination unit determines whether a pause-side cylinder is in an operating state or a pausing state (S101). During a pause period (TS) in which the pause-side cylinder is determined to be in the pausing state by the determination unit, a calculation unit calculates a synchronization correction amount (ΔI) by which the operation-side change speed (VR) of an operation-side rotational phase is to be synchronized with the pause-side change speed (VL) of a pause-side rotational phase (S103). A pause-side control amount (IL) by which the pause-side rotational phase is to be controlled toward a target phase is corrected during the pause period (TS), by using the synchronization correction amount (ΔI) calculated by the calculation unit (S104, S105).
