Hybrid vehicle drive apparatus

Abstract:

A drive apparatus of a hybrid vehicle including a first and second rotors arranged movably in axial direction so as to separate from or approach each other, and a microprocessor. The microprocessor is configured to perform selecting a drive mode from among drive modes including a first mode in which the engine drives a planetary gear mechanism, a second mode in which the engine is stopped, and a third mode in which the engine is driven through the planetary gear mechanism, and controlling a first motor-generator and a clutch mechanism so that the first motor-generator generates regenerative energy when the drive mode is switched from the first mode to the second mode, and then so that the clutch mechanism is engaged and the first motor-generator generates drive torque when the drive mode is switched to the third mode.
