ABSTRACT:
In a vehicle vibration reduction control apparatus for controlling an alternator driven by an engine to charge a battery in such a way that vehicle body vibration due to the engine can be cancelled by alternator vibration, the reference voltage applied to an alternator field coil is reduced by a predetermined value for a predetermined time period, whenever battery terminal voltage exceeds a predetermined level. Since the battery charging rate can be reduced automatically at battery overcharge due to cancellation of engine vibration by alternator vibration, it is possible to prevent the battery from being overcharged when engine vibration increases at idling, for instance.
