<P>PROBLEM TO BE SOLVED: To acquire a reactor current flowing through a reactor of a step-up converter more properly. <P>SOLUTION: At a non-boosting time in which a voltage VH of a driving voltage system power line is not boosted with respect to a voltage VL of a battery voltage system power line by a step-up converter, a learning value G1 is set using a differential value α1 during the non-boosting time, and a detection current ILdet of the reactor is corrected using the set learning value G1 (S110-S160). At a boosting time in which the voltage VH of the driving voltage system power line is boosted with respect to the voltage VL of the battery voltage system power line by the step-up converter, a leaning value G2 is set using a differential value α2 during the boosting time, and the detection current ILdet of the reactor is corrected using the set learning value G2 (S110, S170-S210). <P>COPYRIGHT: (C)2013,JPO&INPIT |
