<P>PROBLEM TO BE SOLVED: To improve energy efficiency of a vehicle and to appropriately charge an auxiliary machine power storage means much more. <P>SOLUTION: In power running when a motor MG2 outputs travel torque, prescribed voltage VL is set in target output voltage V* as a target value of output voltage to a low voltage power line 94 of a DC/DC converter 92. In power regeneration of the motor MG2, voltage VH higher than voltage VL is set in target output voltage V* of the DC/DC converter 92. The DC/DC converter 92 is controlled so that auxiliary machine battery voltage Vb from a voltage sensor 98 becomes target output voltage V*. Thus, energy efficiency of a hybrid vehicle 20 is improved and an auxiliary machine battery 90 is appropriately charged much more. <P>COPYRIGHT: (C)2010,JPO&INPIT |
