<p>An electronic control unit (10) of an internal combustion engine (1) sets a target throttle valve opening based on the manipulated variable of an accelerator pedal and starts an electronic-controlled throttle valve (16) driving after a preset delay time, to thereby accurately predict an actual throttle valve opening at a cylinder suction valve closing and predict a suction air filling volume into the cylinder. In an engine provided with a variable valve timing mechanism (50), the ECU (10) predicts, in addition, a target throttle valve opening at a suction valve closing, predicts, based on the predicted target opening, an actual valve timing at a suction valve closing, and predicts a suction air filling volume into the cylinder at a cylinder suction valve closing based on the above predicted throttle valve opening and the predicted valve timing. Accordingly, it is possible to accurately predict a suction air filling volume even in a variable-valve-timing engine.</p> |
