A motor control apparatus combined with an engine controls both driving and power-generation functions of an electric motor. The motor control apparatus has a determining control for determining an idling state of the engine including an engine rotational speed-detector for detecting engine rotational speed. The control can return the engine rotational speed to a predetermined rotational speed value. The control varies the engine rotational speed by changing an operating state of the motor when an engine rotational speed measured by a detection signal from the engine rotational speed-detector varies from a predetermined rotational speed value for an idling mode of the engine. The engine rotational speed in the idle state becomes essentially constant, and the quietness of the engine is increased.

1. A motor control apparatus combined with an engine and an electric motor, the motor control apparatus having both driving and power-generation functions, and having a determining device for determining an idling state of the engine, the motor control apparatus comprising an engine rotational speed-detector for detecting an engine rotational speed, a controller for controlling the engine rotational speed at a predetermined engine rotational speed value, the controller varying the engine rotational speed by changing an operating state of the electric motor when the engine rotational speed sensed by a detection signal from the engine rotational speed-detector varies from the predetermined engine rotational speed value for the idling state of the engine, wherein in case of the idling state of the engine, when the engine rotational speed is lower than the predetermined engine rotational speed value, the controller controls so as to increase the engine rotational speed by setting the motor in an operation running state so as to return the engine rotational speed to the predetermined engine rotational speed value, and when the engine rotational speed decreases or when the engine rotational speed does not increase, the controller stops the operation running state of the motor.
