    Abstract: PROBLEM TO BE SOLVED: To properly control a valve phase during idle operation of an internal combustion engine, in a variable valve timing mechanism having a structure in which the change ratio (deceleration ratio) of the valve phase with respect to operation quantity of an actuator is changed in response to the valve phase. SOLUTION: An idle time target phase setting part 130 variably sets a target phase CAr in response to an idle target engine speed NIr set by an idle target engine speed setting part 110. In particular, when it is determined by an engine temperature determination part 135 that the engine 1000 is in a cold state, the idle time target phase setting part 130 sets the target phase CAr so that a change range of the valve phase is restricted within a phase area where the deceleration ratio is large and operation noise is relatively suppressed.
