In controlling an engine generating motive power of which an output shaft extracting the generated motive power is connected to a generator motor, an engine control device causes the generator motor to generate motive power when both of a first condition satisfied based on a comparison of an actual revolution speed of the engine with a revolution speed acquired from first and second relationships and a second condition satisfied based on a comparison of a torque of the engine at the actual revolution speed with a torque acquired using the first relationship at the actual revolution speed are satisfied. The first relationship is between the revolution speed of the engine and the torque generated by the engine at the revolution speed, and the second relationship is between the torque and the revolution speed of the engine and defines a magnitude of the motive power generated from the engine.
