Abstract: An electronic control unit (ECU) controls a vehicle capable of externally discharging an electric power via a discharge connector. The vehicle includes: an on-board inverter that adjusts the voltage of an alternating current (AC) power; and a vehicle inlet that discharges to the discharge connector the AC power output from the power converter when the discharge connector is connected to the vehicle inlet.

The processor determines the voltage of the AC power output from the on-board inverter, based on the voltage of the CP terminal.

Abstract: A vehicle includes: an on-board inverter that adjusts the voltage of an electric power; and a vehicle inlet. The vehicle inlet has a CS terminal through which a proximity detection signal for identifying the connection state between a discharge connector and the vehicle inlet is transmitted. An electronic control unit (ECU) includes a processor that selects the voltage of an electric power output from the on-board inverter. When the proximity detection signal is in a first bound (a fourth range or a fifth range), the processor selects AC 100V, and when the proximity detection signal is in a second bound (a fifth range or a sixth range) at least partially different from the first bound, the processor selects AC 200V higher than AC 100V.
