Abstract
A high-level ECU generates a torque command value Taccording to an output request to an electric motor. A low-level ECU calculates a torque command value Tfor correcting the original torque command value Taccording to the operational state of the electric motor and, according to a final torque command value Tf that is set by combining the torque command values Tand T, the electric motor is controlled. The high-level ECU receives from the low-level ECU the torque command value Tand a motor state quantity transmitted thereto and, by a comparison between an actual torque value Tj determined from the motor state quantity and the final torque command value Tf determined with the torque command value Treflected thereto, abnormality in electric motor control is detected.
