ABSTRACT:
An engine control device capable of improving engine efficiency by operating the engine in an area where fuel consumption is small (good) while allowing high responsivity of the engine to be maintained. The object can be achieved by operating to match at a point on a target torque line of a torque diagram and operating an electric motor when a matching point moves on the target torque line in a direction in which a load applied to the engine output shaft becomes large.
