A control device for a vehicle includes a drive shaft, an engine coupled to the drive shaft, an electric motor coupled to the drive shaft, and a control unit. The control unit increases a torque of the electric motor when an accelerator pedal opening increases to equal to or more than a predetermined degree of opening during switching of driving sources, and decreases the torque of the electric motor while increasing the torque of the engine after a change of the torque of the engine turns to increase.

A first case portion includes an end wall portion disposed on a first axial side with respect to a transmission. A second case portion is disposed on the first axial side with respect to a rotor of a rotary electric machine, and includes a first support portion that supports a rotor shaft and a second support portion disposed on a second axial side with respect to the rotor of the rotary electric machine to support the rotor shaft. The second support portion includes a bearing attachment portion to which a rotor bearing for supporting the rotor shaft is attached, and radially extending portion that extends from bearing attachment portion toward an outer side in a radial direction. A speed reducer is disposed between the radially extending portion and the end wall portion in axial direction to face the radially extending portion and the end wall portion in the axial direction.

A vehicle driveline component includes a hollow motor shaft and a link shaft. The hollow motor shaft is supported for rotation about an axis including a plurality of grooves extending along an interior surface of the motor shaft. The link shaft cooperates with the interior surface of the motor shaft and the grooves to define a space between the link shaft and the motor shaft. The grooves are configured to force liquid lubricant to flow through the space in a longitudinal direction relative to the link shaft and the motor shaft when the motor shaft rotates. The link shaft includes a lubricant passage, a first connecting lubricant passage, and a second connecting lubricant passage. The lubricant passage extends along a longitudinal direction of the link shaft. The first and second connecting lubricant passages provide fluid communication between the longitudinal lubricant passage and the space.

It is provided here that the second drive unit can be coupled via a separating clutch to the first drive unit, a transmission output shaft of a transmission which is coupled to the first drive unit.

A vehicle having a longitudinal engine and permanent rear axle drive is proposed, which vehicle has an internal combustion engine and an electric machine, a transfer gearbox distributing drive torques as required to two drive axles, the transfer gearbox having three shafts, a main shaft serving as a drive shaft of the rear axle, a secondary shaft serving as a drive shaft for the front axle, and an intermediate shaft applying a torque, a shifting unit being installed between the reduction gear-box and the power summation gearbox.

A hybrid vehicle in which a running mode can be appropriately shifted without making a driver feel uncomfortable or feel a sense of slowness. A hybrid vehicle includes an engine, a first motor, a second motor, and a clutch that selectively transmits power between the engine and drive wheels. A controller shifts a running mode to the parallel hybrid vehicle mode in a case of accelerating the hybrid vehicle in the electric vehicle mode, if the drive force is greater than a maximum drive force generatable in the electric vehicle mode, and also greater than a required additional drive force as a variable corresponding to a running resistance against the hybrid vehicle running on a predetermined running road at a predetermined vehicle speed by a predetermined drive force that is set in advance based on the vehicle speed and the drive force.
