Abstract
A drive device includes: an input shaft connected to an engine; a first motor-generator; a second motor-generator; a planetary gear unit including three rotating elements; an output gear connected to the planetary gear unit; an output shaft that transmits rotation of the output gear to a driving wheel; and a control device that controls at least one of the first and second motor-generator. The output gear, the planetary gear unit, and the first motor-generator are coaxial with the input shaft. The planetary gear unit is provided radially inside the first motor-generator and is provided at the same position as the first motor-generator in the axial direction. The second motor-generator is provided on an axis different from the input shaft and the output shaft axes. The control device is provided on the side of the output gear, the planetary gear unit, and the first motor-generator that is opposite the input shaft.
