A vehicle control device of a rotary electrical machine control device includes an application voltage generation unit that generates a voltage control signal that is used to apply a power supply voltage to a DC/DC converter at a voltage equal to or higher than the power supply voltage or at a voltage lower than the power supply voltage; and a voltage command value generation unit that generates a motor control signal that controls a drive motor. The voltage command value generation unit performs computation based on overmodulation PWM control as PWM control in the case where the application voltage that is lower than the power supply voltage is applied so as to output the motor control signal having a pulse width longer than a cycle of a PWM carrier.
