Patent ID: 7055474

Claim:
A variable valve control apparatus for an internal combustion engine provided with a variable valve event and lift mechanism that successively varies an operating angle and a valve lift of an intake valve of the internal combustion engine, comprising: a first calculating section that calculates requested opening timing and requested closing timing of said intake valve provided that controlled variable of said variable valve event and lift mechanism is a predetermined value; a second calculating section that calculates a requested operating angle based on said requested opening timing and said requested closing timing; a third calculating section that calculates a deviation between an operating angle corresponding to said controlled variable, and said requested operating angle; an updating section that updates said controlled variable according to said deviation until an absolute value of said deviation reaches a predetermined value or less, and executes the calculations in said first to third calculating sections repetitively based on the post-updated controlled variable; a setting section that sets said controlled variable of the time when the absolute value of said deviation is the predetermined value or less, to a desired value; and a control section that controls said variable valve event and lift mechanism based on said desired value.
