Abstract
A rotary electric machine control device is provided to control a motor having motor winding sets and includes a plurality of inverter circuits and a plurality of control circuits capable of mutual communication. The inverter circuits switch over the current supply to the motor winding sets. The control circuits include driver control sections, which control the inverter circuits provided correspondingly, and abnormality monitor sections, which monitor the abnormality. The abnormality monitor sections monitor the abnormality of the own system and the other system based on the plurality of abnormality information. The driver control sections change a control mode according to the abnormal state. It is thus possible to control the driving of the motor appropriately based on the abnormality state.
