<p>A control apparatus (26) and a control method for a variable valve operating mechanism (100) are employed for a multi-cylinder internal combustion engine (1) including the variable valve operating mechanism (100) and a valve stop mechanism (24, 25). The variable valve operating mechanism (100) includes a variable mechanism portion that changes a valve characteristic of an engine valve (9, 10), and an actuator (120) that drives the variable mechanism portion. The valve stop mechanism (24, 25) stops opening/closing of the engine valve (9, 10) in at least one cylinder. A controlled variable (DT) for the actuator (120) is set so that an actual value (VT) of the valve characteristic matches a target value (VTp). A control characteristic value used to set the controlled variable (DT), and used to make the actual value (VT) match the target value (VTp) is set in a manner 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.</p> |
