Abstract:
1. A control apparatus for an internal combustion engine, the control apparatus comprising: a throttle valve installed in an intake path of the internal combustion engine; at least one actuator capable of changing a torque of the internal combustion engine by a method other than by changing the opening of the throttle valve; a plurality of required torque output means each of which outputs a required torque on the basis of its own purpose to the internal combustion engine; required torque consolidation means for calculating an after-consolidation required torque, the after-consolidation required torque being determined by consolidating the required torques output from the plurality of required torque output means; sensitivity judgment means for judging whether the sensitivity of opening variation of the throttle valve corresponding to torque variation is higher than a reference value; first torque control means which, when the sensitivity is lower than the reference value, causes an actual torque to follow variation of the after-consolidation required torque by changing the opening of the throttle valve in accordance with the variation of the after-consolidation required torque; and second torque control means which, when the sensitivity is higher than the reference value, fixes the opening of the throttle valve and causes the actual torque to follow variation of the after-consolidation required torque by changing the operation amount of the actuator in accordance with the variation of the after-consolidation required torque.
