<p><P>PROBLEM TO BE SOLVED: To prevent deterioration of a battery due to overcharging during deceleration fuel cut and improve fuel economy by lengthening no-power generation time of a generator after completion of fuel cut. <P>SOLUTION: Alternator power generation voltage is controlled to voltage making the battery not charge and discharge to prevent deterioration of the battery when battery overcharge is judged in regeneration power generation control during deceleration fuel cut of an engine. Alternator power generation voltage is lowered and no-power generation control is started to forcibly discharge the battery. Consequently, no-power generation time after restart of fuel supply is lengthened and electric power is supplied from the battery to improve fuel economy during idling or the like. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
