Abstract:
When a power failure does not occur, power supply to a first terminal of a wiper motor is performed by a first battery, and power supply to a second terminal of the wiper motor is performed by a second battery. When a power failure occurs in one of the first battery or the second battery, power supply to the wiper motor is performed by the other battery that is not in power failure.
