<P>PROBLEM TO BE SOLVED: To provide a hybrid vehicle capable of further improving energy efficiency of the whole vehicle. <P>SOLUTION: When traveling while charging a battery with an engine operated, target charge and discharge electric power of the battery is set (a value (Pd-P1) or a value (Pd-P2) in the figure) as electric power in which the sum of loss (shown by broken lines in the figure) in operating the engine that becomes larger as power output from the engine is smaller and loss in charging of the battery that becomes larger as electric power charged to the battery becomes larger and a boosted voltage becomes larger is minimum, and engine command power to be output from the engine is set by subtracting the target charge and discharge electric power from power Pd for travel required for travel. <P>COPYRIGHT: (C)2010,JPO&INPIT |
