Abstract
A rotating electric machine control device has an electronic control unit, or an ECU that controls driving of a motor having motor windings, and includes mutually-communicable plural control units. The control unit includes a basic instruction calculation unit, a field-weakening calculation unit, and a current control calculation unit and a PWM (pulse width modulation) output unit. The current control calculation unit and the PWM output unit generate a PWM signal based on d-axis current instruction values and q-axis current instruction values that are calculated based on basic current instruction values and field-weakening d-axis current instruction value. At least a part of the instruction values used for generation of the PWM signal is shared by the plural control units.
