Abstract
A primary opening amount setting device sets a primary throttle valve opening amount based on an accelerator-pedal operation amount determined by an accelerator operation amount determination device. An injection amount calculation device sets a fuel injection amount based on the primary throttle valve opening amount. A first index value determination device determines a first index value that indicates a state of combustion of an air-fuel mixture in a cylinder of an engine. A secondary opening amount setting device sets a secondary throttle valve opening amount, which is a final target value of an opening amount of a throttle valve, based on the first index value.
