<P>PROBLEM TO BE SOLVED: To restrain power supply from a storage device to a low voltage system, and to supply power with sufficient voltage from a generation device to a motor and the storage device. <P>SOLUTION: When engine speed which drives front wheels is less than a threshold value Neref set as the minimum engine speed required when an alternator generates the power with the sufficient voltage, for supplying the power to a high voltage system which is made by the motor for driving rear wheels and a high pressure battery for supplying the power to the motor; a switching relay for connecting/cutting off the alternator with the high voltage system is switched off (step S120). Therefore, power supply can be restrained from the high pressure battery to the low pressure battery caused due to low generation voltage of the alternator. When the engine speed is at or more than the threshold Neref, the switching relay is switched on (step S130). Thus, it is possible to supply the power with sufficient voltage from the alternator to the motor. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
