Control Device And Abnormality Discernment Method

Abstract: This control device (20) for controlling power conversion devices comprises a first arithmetic processing unit (21) and a second arithmetic processing unit (22) that are connected to each other via a transmission line (L1, L2). A first arithmetic part (31) included in the first arithmetic processing unit (21) determines a basic torque command value, which is a torque command value shared by electric motors provided to a vehicle. A second arithmetic part (41) included in the second arithmetic processing unit (22) adjusts the basic torque command value in accordance with a parameter and thereby determines for each power conversion device a shaft torque command value, which is a torque command value for an electric motor receiving a supply of power from the respective power conversion device. An abnormality discernment part (32) included in the first arithmetic processing unit (21) discerns the presence or absence of an abnormality in at least one of the transmission line (L1, L2) and the second arithmetic part (41) from the basic torque command value and the shaft torque command value.
