<p>PROBLEM TO BE SOLVED: To speedily raise the temperature of an electric power storage device without reference to a difference in travel state when the temperature of the electric power storage device needs to be raised.SOLUTION: An electric motor MG needs to be placed in power operation more by as much as a decrease in efficiency so as to generate a current driving request quantity (including plus and minus quantities) (in other words, so as to maintain current driving force) by decreasing power transmission efficiency during the power operation of the electric motor MG, and electric power (for example, battery current Ibat) carried out of the electric power storage device 54 to the electric motor MG can be increased by increasing electric motor power Pm (>0) while maintaining the current driving force.</p> |
