摘要： A variable valve device has a hydraulic actuator that implements discharge of operating oil in a pressure chamber and a hydraulic control valve that controls supply and discharge of the operating oil to and from the hydraulic actuator by opening and closing, thereby preventing the closing movement of the intake valve. After a signal that closes the hydraulic control valve in a current engine control cycle is output at a prescribed crank angle, the crank angle of a crankshaft, when surge pressure in the pressure chamber has exceeded a prescribed threshold value resulting from closing of the hydraulic control valve, is determined, and at least either an output crank angle or a waveform of the signal that closes the hydraulic control valve is corrected based on the operation start crank angle, and the corrected signal is output to the hydraulic control valve in a next control cycle.
