Abstract:
The valve timing controller for the internal combustion engine determines, based on a control parameter during phase angle feedback control, whether or not the valve timing variable mechanism is pressed against a limiting position defined by a stopper, sets a second target phase angle on a reference rotational phase angle value side of the camshaft by a first predetermined value from a detected real phase angle value of the camshaft when the stopper pressing determination means determines that the valve timing variable mechanism is pressed against the limiting position defined by the stopper, and switches a target phase angle during the phase angle feedback control from the first target phase angle to the second target phase angle.
