Abstract
A hybrid drive apparatus and a control apparatus for controlling the hybrid drive apparatus, a hybrid drive apparatus including a differential device made of a first differential mechanism and second differential mechanism, including four rotary components; and an engine, a first electric motor, second electric motor and an output rotary member, which are respectively connected to four rotary components, wherein one of the four rotary components consists of a rotary element of the first differential mechanism and a rotary element of the second differential mechanism which are selectively connected to each other through a coupling element, and the control apparatus controlling at least one of output torques of the first and second electric motors, to reduce a difference between rotating speeds of the rotary elements of the first and second differential mechanisms selectively connected to each other through the coupling element, to a value not larger than a predetermined threshold value, before the coupling element is brought into an engaged state when the drive system is re-started after the drive system is once placed in an off state.
