Abstract: When a cam shaft phase is changed during engine operation is stopped, a power supply increase control to an electric motor is carried out, according to which a power-supply duty ratio to the electric motor is increased to a predetermined power increase value which is necessary for moving a VVT apparatus during the stop of the engine operation. Then, the power-supply duty ratio is feedback controlled so that an actual changing speed of the cam shaft phase becomes equal to a target changing speed. As a result, the cam shaft phase can be surely changed and operating sound can be reduced by preventing the changing speed of the cam shaft phase from becoming too fast.

Abstract: A control device projects a lock pin to lock a VCT phase in an intermediate lock phase when a lock request occurs. A learning unit learns one of a most retarded phase, a most advanced phase, and an intermediate lock phase, as a reference phase. A control unit sets a target phase according to the reference phase and controls the control device. A monitor unit determines that the VCT phase has passed through the intermediate lock phase when the lock request occurs before completion of learning of the reference phase, and when a change in the VCT phase becomes greater than a threshold. The threshold is set to be greater than a sum of i) a design value of a phase difference between the intermediate lock phase and one of the most retarded phase and the most advanced phase and ii) a range of a product variation of the phase difference.
