<P>PROBLEM TO BE SOLVED: To more appropriately perform control of a boost converter and abnormality detection of a circuit including the boost converter. <P>SOLUTION: When a voltage difference ΔVH obtained by subtracting voltage VH generated from a voltage sensor from a voltage command VH* becomes first voltage VH1 or more during the control of the boost converter so that the voltage VH of a drive voltage system detected by a voltage sensor becomes the voltage command VH* set so as to gradually approach target voltage VHtag, voltage obtained by subtracting second voltage VH2 equal to or less than the first voltage VH1 from the voltage command VH* is reset as the voltage command VH* and the voltage command VH* is set so that the reset voltage command VH* gradually approaches the target voltage VHtag. When the reset of the voltage command VH* of the drive voltage system is continuously generated by the number of times of threshold Cref within predetermined time T1 predetermined for abnormality detection, occurrence of abnormality of a booster circuit including the boost converter and the voltage sensor is detected. <P>COPYRIGHT: (C)2013,JPO&INPIT |
