A MGECU includes a locked state check part for checking whether a motor generator is in a locked state, a current value check part for checking whether a current command value or an actual current value as a current value is in a predetermined disconnection undetectable range including a current value of zero, a phase shift part for shifting a phase of the current command value so that the current command value is outside the disconnection undetectable range with a direction of rotation being unchanged in a case that the motor generator is determined to be in the locked state and the current value is determined to be in the disconnection undetectable range, and an abnormality check part for checking whether the motor generator has a disconnection in windings based on a result produced by controlling the motor generator with a phase-shifted current command value. |
