A rotating electric machine control device includes a first system controller and a second system controller, an overheat protection controller and an abnormality detector. The overheat protection controller includes a temperature estimator and a restricted current calculator. The temperature estimator estimates system temperatures as well as other temperature, including a shared component temperature of a shared component that is connected to both of plural systems in a shared manner. The restricted current calculator calculates restricted current values, based on the system temperatures and the shared component temperature. At least one of the system temperatures, the shared component temperature, and/or the restricted current values is changed from an all-systems normal time, when at least one of a plurality of systems is abnormal.
