Abstract:
1. An apparatus for controlling power of an engine that is mounted on a vehicle having a powertrain coupled to the engine, the apparatus comprising: a first computation section for computing a first torque balance that represents a difference between engine generated torque, which is torque generated by the engine, and estimated engine load torque, which is load torque applied to the engine; a second computation section for computing a second torque balance that represents a change of the engine speed, wherein the second computation section computes the second torque balance based on the change of the engine speed over a predetermined period, the moment of inertia of the engine, and the moment of inertia of the powertrain; a third computation section for computing a difference between the first torque balance and the second torque balance as a torque balance difference; and a correction section for correcting the engine power based on the torque balance difference.
