CONTROLLER FOR ENGINE

摘要

An ECU includes: an engine control unit (8100) that controls devices provided for an engine on the basis of a target engine rotational speed; and an engine model (8300) that calculates the target engine rotational speed such that the target engine rotational speed varies in accordance with a target engine torque and an actual engine rotational speed (NE) in a steady state, and that calculates the target engine rotational speed such that the target engine rotational speed varies in accordance with the target engine torque independently of the actual engine rotational speed (NE) in a transient state in which the engine is unstable as compared with the steady state. When the engine is controlled by the thus configured ECU, the control accuracy is improved.
