1. A drive apparatus for a hybrid vehicle,
the drive apparatus including: an engine; a first motor generator; an output shaft for outputting drive power from drive wheels of the vehicle; a second motor generator which transmits power to the output shaft; a power split mechanism having a first rotational element, a second rotational element, and a third rotational element which are capable of differentially rotating with each other, the first rotational element being connected to the engine, and the second rotational element being connected to the first motor generator; a clutch operating between an engaging state where the third rotational element of the power split mechanism and the output shaft are connected with each other and a release state where the third rotational element and the output shaft are separated from each other; a lock mechanism operating between a lock state where the third rotational element of the power split mechanism is locked so as not to rotate and an unlocked state where the third rotational element locked is released; and an electronic control unit controlling the engine, the first motor generator, the second motor generator, the clutch, and the lock mechanism, wherein the electronic control unit is programmed so as to include rotating speed control programming instructions that are executed to control a rotating speed of the third rotational element before a control to the clutch or the lock mechanism is performed, and the rotating speed control programming instructions are executed to control the rotating speed of the third rotational element by controlling the first motor generator after a rotating speed of the engine is deemed to be zero by executing an engine stop control for stopping the engine, when a condition which the control to the clutch or the lock mechanism is performed is satisfied while the engine is running. |
