Abstract: In an apparatus for, controlling a variable valve timing mechanism that variably controls valve timing of an engine by changing a rotation phase of a camshaft relative to a crankshaft due to friction braking of an electromagnetic brake, the rotation phase is controlled while limiting a change rate of the rotation phase.
