御装置。 After the engine starts, when the throttle opening command value gradually increases to a certain value according to the amount of depression of the accelerator pedal, the throttle opening detection section detects behavioral quantities such as hunting and steady-state deviation of the throttle opening, and the throttle opening a gain setting unit that appropriately sets a control gain of the throttle according to the behavior amount of the throttle opening detected by the degree detection unit;
A throttle actuator control device, characterized in that a throttle opening behavior caused by operating characteristics of the throttle actuator is suppressed and controlled by a throttle control gain set by the gain setting section.
