ABSTRACT:
A throttle control apparatus of an internal combustion engine comprises an accelerator opening detector, an engine revolution speed detector, a throttle actuator and a control unit constructed so as to generate and output, to the throttle actuator, a throttle driving signal for operating the throttle valve according to a throttle opening pattern determined on the basis of an accelerator opening, an accelerator opening speed and engine revolution speed, the throttle opening pattern includes a first target opening to which throttle valve is opened upon a rapid accelerator operation and which is determined according to an accelerator depression quantity, an accelerator depression speed and an engine revolution speed, a second target opening to which said throttle valve is opened after a predetermined time lapsed from the starting of the rapid accelerator depression and which is determined according to an accelerator depression quantity, an accelerator depression speed and an engine revolution speed.
