<p>A controller of an internal combustion engine having a variable valve system for varying the opening area (valve lift) or a working angle (valve opening period) of at least one of an intake valve and an exhaust valve, wherein a cylinder pressure is calculated based on the opening area or working angle of at least one of the intake valve and exhaust valve varied by the variable valve system, and the internal combustion engine is controlled based on the cylinder pressure, whereby the internal combustion engine can be controlled more appropriately based on not only the cylinder pressure at the time of a peak combustion pressure but also on the cylinder pressure at the other times as in the control using a combustion pressure sensor.</p> |
