Abstract: A control device is configured, if, although the control device has caused a cam switching device to perform a first cam switching operation for switching the profiles of all the valve-driving cams of a plurality of cylinders from a first profile to a second profile, the profiles of all the valve-driving cams of the plurality of cylinders do not coincide with the second profile, to cause the cam switching device to perform a second cam switching operation for switching the profile of the valve-driving cam for at least one or more normal cylinders that are one or more cylinders at which the switching of profiles to the second profile has succeeded.

Abstract: Provided is a control device for an internal combustion engine equipped with a cam switching device including a cam groove provided on the outer peripheral surface of a camshaft and an electromagnetic solenoid type actuator capable of protruding, toward the camshaft, an engagement pin that is engageable with the cam groove. The control device is configured, in causing the cam switching device to perform a cam switching operation, to perform energization of the actuator such that the engagement pin is seated on a forward outer peripheral surface, and to more lower, when an electric current (coil current) flowing through the actuator as a result of the energization is greater, an average electric voltage per unit time applied to the actuator in protruding the engagement pin toward the cam groove from the forward outer peripheral surface.

Abstract: At crank angle CA10 at which the switch request of the drive cam was issued, the ejection operations of the pins at all the solenoid actuators started simultaneously. The ejected pins are seated on the cam carriers at crank angle CA12. The pin seated on the cam carrier moves along the grooves in accordance with the rotation of the cam carrier. The earliest finish timing of the switch operation of the drive cam is at crank angle CA13 (#4 cylinder). At the crank angle CA13, drive of the fuel injector and the ignition device in each cylinder is permitted.

Abstract: When a stop request to the engine is issued, it is determined whether or not all of the drive cams are large cams. When it is determined that at least one of the small cams is included in the drive cams, the engine is continued to drive for a while and a switch control for switching the drive cams from the small cams to the large cams is executed within the duration. A self-holding type solenoid is used to switch between the small cams and the large cams. In the switch control, a permission to stop the engine is output at a timing when the “pin protrudable section” of the final cylinder #2 has elapsed.
