  • Patent number: 8725332
    Abstract: A hybrid vehicle includes a regenerative charging area detection section, a recovery loss estimation section, and a motor use ratio increase section. The regenerative charging area detection section detects arrival of a regenerative charging possible area in which a regenerative charging from a motor to a battery is possible. The recovery loss estimation section estimates a recovery loss of the regenerative charging based on a regenerative charge amount in the regenerative charging possible area and a current remaining battery amount in response to detection by the regenerative charging area detection section. In response to estimation by the recovery loss estimation section, before the arrival at the regenerative charging possible area, the motor use ratio increase section increases a use ratio of the motor so as to decrease a remaining battery amount while limiting the temperature of the battery to a predetermined temperature range.
