摘要:
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.

In an electric vehicle, an automatic transmission is provided between a differential unit and drive wheels. The differential unit includes a motor-generator and a power split device, and the motor-generator is cooled by lubricant of the automatic transmission. A battery charger is operable to charge a power storage device using a power supply outside the vehicle. When the temperature of the lubricant is lower than a predetermined temperature upon execution of charging of the power storage device using the charger, and the automatic transmission is in a neutral state, or a power cutting-off state, the controller rotates the motor-generator of the differential unit so as to perform warming control for raising the temperature of the lubricant.

A hybrid vehicle includes a clutch on a power transmission path between a motor generator and a driving wheel. If the vehicle moves backward when the vehicle starts forward acceleration from standstill on an ascending slope, the charging level of the battery that is attributable to power generation by the motor generator due to the backward travel is compared with a current maximum charging power of the battery. If the charging level of the battery is greater, the quantity of slippage of the clutch is controlled according to the excess to lower the rotational speed of the motor generator, hence to lower the power generation. That enables an increase in the torque of the motor generator within the range in which the battery may be charged. Performance is thus improved during acceleration from standstill.
