A vehicle drive device , comprising: an input member that is drivingly coupled to an internal combustion engine (EG); an output member that is drivingly coupled to wheels (W); a first rotating electrical machine (MG1) and a second rotating electrical machine (MG2); a first transmission system (T1) that drivingly couples the first rotating electrical machine (MG1) and the input member ; a second transmission system (T2) that drivingly couples the second rotating electrical machine (MG2) and the output member ; a first hydraulic pump that is driven by a driving force transmitted through the second transmission system (T2) such that even while the internal combustion engine (EG) is stopped, oil is supplied to the second transmission system (T2) by the first hydraulic pump when the vehicle is travelling by the driving force of the second rotating electrical machine (MG2), a second hydraulic pump that is driven by a dedicated driving force source , the dedicated driving force source being independent of the first transmission system (T1) and the second transmission system (T2); a first oil passage (PS1) that supplies oil discharged from the first hydraulic pump to the second transmission system (T2); a second oil passage (PS2) that supplies oil discharged from the second hydraulic pump to the first transmission system (T1); a third oil passage (PS3) that supplies the oil discharged from the second hydraulic pump to the first rotating electrical machine (MG1); a fourth oil passage (PS4) that supplies the oil discharged from the second hydraulic pump to the second rotating electrical machine (MG2); characterized in that a fifth oil passage (PS5) supplies the oil discharged from the first hydraulic pump to the first rotating electrical machine (MG1). an input member that is drivingly coupled to an internal combustion engine (EG); an output member that is drivingly coupled to wheels (W); a first rotating electrical machine (MG1) and a second rotating electrical machine (MG2); a first transmission system (T1) that drivingly couples the first rotating electrical machine (MG1) and the input member ; a second transmission system (T2) that drivingly couples the second rotating electrical machine (MG2) and the output member ; a first hydraulic pump that is driven by a driving force transmitted through the second transmission system (T2) such that even while the internal combustion engine (EG) is stopped, oil is supplied to the second transmission system (T2) by the first hydraulic pump when the vehicle is travelling by the driving force of the second rotating electrical machine (MG2), a second hydraulic pump that is driven by a dedicated driving force source , the dedicated driving force source being independent of the first transmission system (T1) and the second transmission system (T2); a first oil passage (PS1) that supplies oil discharged from the first hydraulic pump to the second transmission system (T2); a second oil passage (PS2) that supplies oil discharged from the second hydraulic pump to the first transmission system (T1); a third oil passage (PS3) that supplies the oil discharged from the second hydraulic pump to the first rotating electrical machine (MG1); a fourth oil passage (PS4) that supplies the oil discharged from the second hydraulic pump to the second rotating electrical machine (MG2); characterized in that a fifth oil passage (PS5) supplies the oil discharged from the first hydraulic pump to the first rotating electrical machine (MG1). <EOS>
