<P>PROBLEM TO BE SOLVED: To provide a vehicle control device, capable of improving fuel consumption and silence in a vehicle. <P>SOLUTION: The vehicle includes driving wheels; a motor generator MG2 generating driving torques of the driving wheels; an electric oil pump 33 feeing lubricating oil to generate an original hydraulic pressure; and an apparatus using the lubricating oil fed out of the electric oil pump 33. The control device 27 switches the rotating speed of the oil pump 33, in interlocking with the control state of the apparatus, between a first rotating speed S2 for generating a first hydraulic pressure and a second rotating speed X1 for generating a second hydraulic pressure higher than the first hydraulic pressure. Preferably, the control device 27 temporarily raises the rotating speed of the oil pump 33 to a third rotating speed X0 further higher than the second rotating speed X1 according to transition of the control state of the apparatus from a first state needing the first hydraulic pressure to a second state needing the second hydraulic pressure. <P>COPYRIGHT: (C)2007,JPO&INPIT |
