A control device for a driving apparatus. The control device is configured with a device that controls the rotary electric machine via the inverter, a device that determines whether a disconnect condition of the main power supply is satisfied, and a device that obtains an estimated field amount that is an estimated value of the field flux supplied from the rotor to the stator. The control device is also configured with a device calculates an induced voltage that is induced in the coil, and a device that determines whether an overvoltage state in which the induced voltage exceeds a voltage resistance of the inverter exists. If it is determined that an overvoltage state exists when the disconnect condition is satisfied, connection with a main power supply is maintained until the overvoltage state is eliminated. The rotary electric machine is controlled by weakening the field flux to the coil. |
