<p>PURPOSE: To quickly stabilize the idle rotation speed to a set value while restraining fluctuation of battery voltage. CONSTITUTION: A switch 21 is opened and closed in such a direction as to decrease the difference between the rotational speed and the set value on the basis of the difference when the idle state is judged. For example, when the rotational speed is not less than the set value, a load of a generator 1 is increased by closing the switch 21, and generator driving torque is increased, and the rotational speed of the engine 2 is decreased. When the rotational speed is less than the set value, the load of the generator 1 is decreased by opening the switch 21, and generator driving torque is decreased, and the rotational speed of the engine 2 is increased. Thus, the actual electric load 25 is increased and decreased according to the increase of output current of the generator 1 for increasing and decreasing load torque of the engine 2, thereby, fluctuation of battery voltage can be restrained.</p> |
