A vehicle warm-up control apparatus includes: a motor; an inverter; an electric storage device; a boost converter connected to a low-voltage-side power line and a high-voltage-side power liner; and a control unit for controlling the inverter and the boost converter, the boost converter including a first switching device as an upper arm, a second switching device as a lower arm, and a reactor. Further, the second switching device is composed of a semiconductor device variable in resistance value, and when warm-up is requested, the control unit executes warm-up control to set the resistance value of the second switching device higher than the resistance value during operation when the warm-up is not requested, and supply heat generated in the second switching device by passing current through the second switching device to a device for which the warm-up is requested.
