<p><P>PROBLEM TO BE SOLVED: To properly determine that an abnormality occurs in at least one of two current sensors for detecting a current flowing in a reactor of a voltage boosting converter. <P>SOLUTION: A deviationΔIL is calculated by applying a predetermined low-pass filter to an absolute value of a difference between the currents detected by two current sensors 47a, 47b for detecting the current flowing in the reactor L of the voltage boosting converter 30. When the calculated deviationΔIL is a threshold Iref or more, it determines that the abnormality occurs in at least one of the two current sensors 47a, 47b. The threshold Iref is an absolute value of target power P* output from motors MG1, MG2, an absolute value of output power P output from the motors MG1, MG2, absolute values of torques Tm1, Tm2 from the motors MG1, MG2, an absolute value of a charge/discharge current IB of a battery 26, or a value set so as to be increased when a voltage VH of a high voltage system is increased. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
