Abstract:
A vehicle includes: an engine; a first electric motor capable of inputting or outputting power; a power split mechanism including a sun gear, a ring gear and a planetary carrier rotatably revolvably supporting pinion gears meshing with the sun and ring gears. The planetary carrier, the sun gear and the ring gear are respectively coupled to an engine output shaft, a first electric motor rotary shaft and a drive wheel. The vehicle further includes a second electric motor capable of inputting or outputting power to or from the drive wheel; and a control device setting an engine operation range determined by a limit value of a rotation speed of the pinion gears. To increase durability of the pinion gears the limit value is higher at a high engine rotation and low vehicle speed side than at a low engine rotation and high vehicle speed side. Engine operation is controlled on the basis of the set engine operation range.
