<P>PROBLEM TO BE SOLVED: To provide a simple and inexpensive motor control apparatus capable of continuing vehicle traveling control even when some abnormality occurs in any of current sensors in each phase. <P>SOLUTION: A motor control apparatus 100 includes a first and a second current sensor U1, U2, V1, V2 for detecting an electrical current in a U phase or a V phase; a W phase current sensor W for detecting an electrical current in a W phase; and abnormality detection means for detecting abnormality occurring in any of the first and the second current sensor when a current value difference detected by the first and the second current sensor 130 is equal to or larger than a predetermined threshold value. The abnormality detection means determines that abnormality occurs in the first or the second current sensor and controls a three-phase motor by using information detected by the current sensor in which no abnormality occurrence is determined, based on the current value detected by the W phase current sensor and the current value detected by the first and the second current sensor. <P>COPYRIGHT: (C)2012,JPO&INPIT |
