(54) HYBRID DRIVING APPARATUS FOR VEHICLE


(57) A hybrid drive system configured to selectively establish one of a first drive mode in which a first motor/generator MG1 is operated with a drive force of an engine 12, to generate an electric energy and in which a vehicle drive force is generated primarily by a second motor/generator MG2, and a second drive mode in which the vehicle drive force is generated by the engine 12, and at least one of the first motor/generator MG1 and second motor/generator MG2 is operated to generate an assisting vehicle drive force, as needed, and further configured such that an amount of a working oil to be supplied to the first motor/generator MG1 is larger in the first drive mode than in the second drive mode, permitting sufficient cooling of the electric motor depending upon a selected one of the vehicle drive modes.
