Abstract:
1. A variable valve control apparatus for an internal combustion engine, comprising: a variable valve mechanism that varies operating characteristics of an engine valve of the internal combustion engine; a rotating speed detector that detects an engine rotating speed; and a controller, which comprises: a rotational acceleration calculating section that calculates the rotational acceleration of the engine based on said detected engine rotating speed; an inertia torque calculating section that calculates the inertia torque transmitted to said variable valve mechanism, based on said calculated rotational acceleration; an inertia torque correction amount calculating section that calculates a correction amount of a manipulated variable for said variable valve mechanism, the correction amount being in compliance with said calculated inertia torque; a manipulated variable correcting section that corrects the manipulated variable for said variable valve mechanism with said calculated correction amount; and a control section that controls said variable valve mechanism based on said corrected manipulated variable.
