<P>PROBLEM TO BE SOLVED: To turn off a system main relay which connects a battery to a power supply circuit in a non-arc state, and to shift to a battery-less traveling when any battery abnormality is generated. <P>SOLUTION: When an abnormality occurs in a battery 100, a control device 50 turns off the gate of a boosting converter 102, and permits the operations of inverters 104 and 106, suppresses an over-voltage state by performing the power balance of motor generators MG1 and MG2 so that a high pressure side voltage VH and a battery side voltage VL satisfy VH>VL, performs the off control of the system main relay SMR, and shifts the system main relay to battery-less traveling. <P>COPYRIGHT: (C)2011,JPO&INPIT |
