Abstract

In a system for controlling an internal combustion engine (12) mounted on a vehicle (10) and having an actuator (44) that drives a throttle valve (24) installed in an intake pipe (23) of the engine and an accelerator (17) installed to be operable by the operator, it is configured to comprise an actuator controller that controls the operation of the actuator such that the detected actual opening of the throttle valve becomes the desired opening calculated based on accelerator opening APS and engine speed NE, when the engine is determined to be under no load. With this, it becomes possible to prevent a stall of the engine without impairing operating feel of the operator even when an accelerator is rapidly opened during no load operation of the engine.
