<P>PROBLEM TO BE SOLVED: To allow controllability of load torque of an alternator to be secured by preventing suppression of power generation current of the alternator during engine revolution stop control. <P>SOLUTION: Prior to the start of engine revolution stop control (alternator F/B stop control) for feed-back control of load torque of an alternator 33 so as to match an actual engine revolution behavior to a target trajectory, consumption power increase control for increasing the power consumption of a vehicle is performed for a predetermined time. By the power consumption increase control, power of a battery 32 is consumed to increase electric energy chargeable to the battery 32 by just that much, thereby increasing electric energy (= consumed electric energy of the vehicle + chargeable electric energy of the battery 32) acceptable for the vehicle. Thereby, during the engine revolution stop control, power generation electric energy of the alternator 33 is prevented from exceeding the electric energy acceptable for the vehicle, thus preventing the power generation current of the alternator 33 from being suppressed by a regulator. <P>COPYRIGHT: (C)2012,JPO&INPIT |
