Abstract: A vehicle driving apparatus including a first oil pump driven by an internal combustion engine; a second oil pump connected to a torque transmission portion transmitting a driving force of the second motor generator to a drive wheel; a hydraulic circuit configured so that a lubricating oil is supplied from the second oil pump to a lubrication portion in a first mode in which a vehicle travels while stopping the internal combustion engine, and the lubricating oil is supplied from the first and second oil pumps to the lubrication portion in a second mode in which the vehicle travels while driving the internal combustion engine; a slip detector detecting a slip state of the drive wheel, and a control unit switching to the second mode when the slip state is detected during the first mode.

Abstract: An oil pressure control device includes: line pressure adjusting means for adjusting the line pressure; line pressure switching means for switching, in two stages, the line pressure adjusted by the line pressure adjusting means; a linear solenoid valve that adjusts a required oil pressure for engaging frictional engagement elements with one another by engagement force, which is required thereby, by adjusting a pressure of hydraulic oil with the line pressure; and control means for controlling a value of a current supplied to the linear solenoid valve. The control means performs control to differentiate the value of the current, which is supplied to the linear solenoid valve in order to adjust (obtain) the same required oil pressure, in response to the line pressure switched by the line pressure switching means.
