A hybrid drive unit includes a three-element planetary gear (P1) coupled to two motors (MG1,MG2), and a reduction planetary gear (P2) which is drivingly connected to the three-element planetary gear (P1) and switches modes by controlling a clutch (C-1) and a brake (B-1). A three-element direct drive mode is able to be achieved by providing another clutch (C-2) which couples together any two elements of the reduction planetary gear, and locking up the reduction planetary gear. As a result, motor output is reduced compared with a four-element direct drive mode of related art during high-speed running, and energy recovery during regeneration is also able to be improved. |
