ABSTRACT:
An internal combustion engine controller, is used with a fuel-based torque-on-demand control type, multi-cylinder, direct-injection internal combustion engine, to provide an air flow rate control that excels in response and convergence. The internal combustion engine controller includes a section for computing a target throttle opening from operating conditions, which in turn includes a first computing section for determining a target throttle opening by feedback control in accordance with operating conditions including an intake air flow rate; a second computing section for determining a target throttle opening by feed-forward control in accordance with operating conditions; and a third computing means for determining a target throttle opening based on the target throttle opening value determined by the first computing means and the second computing means.
