Abstract:
1. An apparatus for controlling a variable valve operating mechanism that performs a valve lift amount control on at least one of an intake valve and an exhaust valve of an internal combustion engine to successively vary a valve lift amount of said intake valve or said exhaust valve, comprising: a first inputting section that is configured to input a valve timing operating condition of said intake valve or said exhaust valve controlled by a variable valve timing mechanism provided in said internal combustion engine; a second inputting section that is configured to input an operating condition of a valve lift amount of said intake valve or said exhaust valve controlled by said variable valve operating mechanism; a storage section that is configured to store a first limit value and a second limit value, a limit value setting section that is configured to set a limit value for limiting a control range of said valve lift amount by referring to said storage section on the basis of the inputted valve timing operating condition during feedback-controlling of said variable valve operating mechanism in accordance with the inputted operating condition of the valve lift amount; and a control section that is configured to feedback-control said valve lift amount within the control range set by said limit value setting section.
