Abstract: A drive system including first and second power sources, first and second output shafts, a differential mechanism, and an electronic control unit, and a control method therefor are provided. The differential mechanism is configured such that the second power source is connected to a first rotating element, one output shaft of a vehicle is connected to a second rotating element, and the other output shaft of the vehicle is connected to a third rotating element so as to be able to be connected to or disconnected from the third rotating element by a connect-disconnect mechanism, and includes at least one of an engagement element that selectively engages any two of the three rotating elements and an engagement element that selectively engages the third rotating element to a fixing member. The electronic control unit is configured to, during turning (ST3), prohibit switching between a first drive mode and a second drive mode (ST4).

Abstract: A vehicle drive device and a control method therefor are provided. The vehicle drive device includes: a power source including a first rotating electrical machine (MG2); a second rotating electrical machine (MGF); a differential unit including three rotating elements to which a first output shaft, a second output shaft, and the second rotating electrical machine (MGF) are connected; and an electronic control device. The electronic control device regeneratively controls the first rotating electrical machine (MG2) and the second rotating electrical machine (MGF) in such a manner that negative torque is applied to the first output shaft and the second output shaft, when performing regenerative control by the second rotating electrical machine (MGF) in a drive mode in which torque from the power source is distributed to the first output shaft and the second output shaft by controlling torque of the second rotating electrical machine (MGF) during deceleration of a vehicle (ST7, ST8, ST10, ST11).

Abstract: It is provided a control device for a hybrid vehicle including a controller configured to control an engine, a first motor, and an automatic transmission and a control method of the hybrid vehicle. The controller is configured to determine whether or not an operation state of the engine is changeable, when an upshift of the hybrid vehicle is performed, decrease torque of an input shaft of the automatic transmission by outputting negative torque acting to decrease the torque of the input shaft of the automatic transmission from the first motor when a prohibition condition that the operation state of the engine is not changeable is established, and decrease engine torque output from the engine to decrease the torque of the input shaft of the automatic transmission to be decreased accompanied by the upshift when the prohibition condition is not established and the operation state of the engine is changeable.
