Abstract:
Each of two control units configured in a double system has a CPU, each CPU obtains input information of the control unit of the other CPU, each CPU independently drives an electric motor at a normal time, and continues the motor drive by utilizing the input information of the control unit of the other CPU when an abnormality relating to input information is detected, and when an abnormality relating to information other than input information is detected, the control unit in which the abnormality has occurred controls the electric motor so as to continue the drive or stop the drive in accordance with details of the abnormality, and the control unit on the normal side controls the electric motor so as to at least continue the drive as normal.
