Title:
VALVE OPENING/CLOSING TIMING CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/051778
Kind Code:
A1
Abstract:
A valve opening/closing timing control device with which arrival at a phase at which locking is possible can be detected reliably, and a transition to a locked state can be made, even when a phase sensor with low resolution is used. A control mode for lock transition control is set such that when a phase sensor detects that the relative rotational phase has arrived at a sequence region G, displacement is stopped and the relative rotational phase is displaced toward a locked phase M. In this control, when the relative rotational phase is in the sequence region the relationship between the output timing of a detection signal from the phase sensor and the displacement speed of the relative rotational phase is set such that the detection signal from the phase sensor is detected at least one time.
