ABSTRACT:
An engine control apparatus executes feedback control on the basis of throttle valve position data in order to electronically drive a throttle valve in accordance with an operation of an accelerator pedal. The throttle valve is connected to a motor through a wire. The control apparatus calculates a signal for the feedback control so as to suppress resonance of the throttle valve caused by connection through the wire.
