On a vehicle, there are mounted a differential device including a sun gear, a ring gear and a carrier, a first motor generator coupled to the sun gear, a second motor generator coupled to the ring gear, an automatic transmission provided between the ring gear and a drive wheel, an engine coupled to the carrier, and a brake suppressing the rotation of the carrier. In the vehicle, a traveling mode is selected from a first mode in which traveling is performed by using a torque outputted from the first and second motor generators in a state where the brake is engaged, and a second mode in which the traveling is performed by operating the engine in a state where the brake is disengaged. When the traveling mode is switched from the first mode to the second mode, the traveling mode is switched to the second mode after the automatic transmission is downshifted.

An engine, a transmission unit which is connected to the engine and is shifted by an engagement apparatus, and a differential unit which connects the transmission unit and a drive wheel are included. The differential unit includes a first rotary element connected to an output element of the transmission unit, a second rotary element connected to a first rotary machine, and a third rotary element connected to the drive wheel. When an output from the first rotary machine is limited, the engagement apparatus is slipped and an operation point of the engine is changed. The change of the operation point can cause an increase in torque of the engine.

A driving device for a hybrid vehicle includes a transmission unit configured to output a rotation of an engine while changing rotating speed of the engine; and a first rotating electric machine. The first rotating electric machine is configured to supply a torque for increasing the rotating speed of the engine at the time of starting up of the engine to the engine through the transmission unit. At the time of starting up of the engine, the gear shift stage of the transmission unit is switched to an overdrive state. Thus, a torque sufficient for starting up of the engine can be supplied to the engine, and hence the engine can be appropriately started up.

A hybrid vehicle includes electrical storage devices, a charging device, a motor generator, a diode, an outlet and a relay. The first electrical storage device stores driving electric power. The charging device charges the first electrical storage device with the user of a power supply outside the vehicle. The motor generator has a power generation function. The second electrical storage device stores electric power that is generated by the motor generator. When electric power is output to a device outside the vehicle from the outlet, the relay limits electric power, which is output from the first electrical storage device, such that electric power stored in the second electrical storage device is output.

A vehicle control device is configured to select a single motor running, a multiple motor running and an engine running, such that a level of a charging capacity of an electric storage device in which the multiple motor running is selectable is higher than a level of the charging capacity in which the single motor running is selectable. During the single motor running performed with the charging capacity being equal to or greater than a first threshold value, the control device is configured, upon increase of the drive force requested by a driver of the vehicle, to select the multiple motor running when the charging capacity is equal to or greater than a second threshold value that is higher than the first threshold value, and to select the engine running when the charging capacity of the electric storage device is less than the second threshold value.
