Abstract
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.
