Abstract
An engine control apparatus includes a throttle valve, an accelerator opening detector, a throttle opening controller, and an intake air density detector. The throttle valve is configured to regulate an intake air volume of an engine. The accelerator opening detector is configured to detect an accelerator opening that is an operation amount of an accelerator operation member with which a driver operates an accelerator. The throttle opening controller is configured to increase a throttle opening of the throttle valve in accordance with an increase in the accelerator opening. The intake air density detector is configured to detect information about an intake air density of the engine. In a low intake air density state where the intake air density is a predetermined value or lower, the throttle opening controller decreases a sensitivity of the throttle opening relative to the accelerator opening in a partial range of a range where the accelerator opening is variable.
