<P>PROBLEM TO BE SOLVED: To suppress the efficiency of a whole vehicle from being deteriorated in an energy recirculation mode that at least a portion of a power generated by a motor is consumed by a power generator by simple control. <P>SOLUTION: In an energy recirculation mode, correction rotational frequency ΔNe which is inclined to increase according as a post-boosting target voltage VH* becomes high is derived based on a correction rotational frequency setting map (S100), and rotational frequency to be obtained by adding the correction rotational frequency ΔNe to the target rotational frequency Ne* of an engine is reset as a target rotational frequency Ne*, and target torque Te* is reset so that an engine command power Pe* can be output when the engine is operated by the post-resetting target rotational frequency Ne* (S110). Thus, it is possible to suppress lowering of the efficiency of the whole vehicle only by simple control that the operation point of the engine is corrected by the post-boosting target voltage VH* and the correction rotational frequency ΔNe to be obtained from the correction rotational frequency setting map in the energy recirculation mode. <P>COPYRIGHT: (C)2010,JPO&INPIT |
