    • PROBLEM TO BE SOLVED: To provide, in a system which controls a variable valve operating mechanism by calculating an operating characteristic of a valve operating system based on a sensor output, a technique of controlling the operating characteristic of the valve operating system with high accuracy, even when the operating characteristic based on the sensor output cannot be calculated. SOLUTION: The control system includes a state quantity detection means for detecting a state quantity of an internal combustion engine correlating with an operating characteristic of a valve operating system. In the control system, a combination of the operating characteristic of the valve operating system and a state quantity of the internal combustion engine is learned as an estimated reference value. The state quantity of the internal combustion engine is detected by the state quantity detection means if the operating characteristic of the valve operating system cannot be calculated based on the sensor output. The operating characteristic of the valve operating system is estimated based on the detected state quantity and on the estimated reference value learned when the operating characteristic of the valve operating system can be calculated based on the sensor output. A control is executed for driving the variable valve operating mechanism such that the operating characteristic of the valve operating system becomes a prescribed target operating characteristic based on the estimated operating characteristic of the valve operating system.
