Beschreibung
Zusammenfassung:	A control apparatus and a control method for a variable valve operating mechanism are employed for a multi-cylinder internal combustion engine including the variable valve operating mechanism and a valve stop mechanism. The variable valve operating mechanism includes a variable mechanism portion that changes a valve characteristic of an engine valve, and an actuator that drives the variable mechanism portion. The valve stop mechanism stops opening/closing of the engine valve in at least one cylinder. A controlled variable for the actuator is set so that an actual value of the valve characteristic matches a target value. A control characteristic value used to set the controlled variable, and used to make the actual value match the target value, is set such that when a reduced-cylinder operation is performed, the control characteristic value is different from the control characteristic value when an all-cylinder operation is performed.
