A vehicle cleaner system includes a cleaner unit discharges a cleaning fluid toward a cleaning target mounted on a vehicle; a motor pump supplies the cleaning fluid to the cleaner unit; a normally closed type solenoid valve provided between the cleaner unit and the motor pump and switches between permission and non-permission of movement of the cleaning fluid from the motor pump to the cleaner unit; and a cleaner control unit controls the motor pump and the solenoid valve. The cleaner control unit sets an operation stop time period for stopping an operation of at least one of the motor pump and the solenoid valve, and after the cleaning fluid is discharged to the cleaning target, stops the operation of at least one of the motor pump and the solenoid valve during the operation stop time period based on a predetermined condition.

Vehicle cleaner system

Provided is a vehicle cleaner system with which it can be ascertained which cleaner has broken down. A vehicle cleaner system comprises: a plurality of cleaner units; a motor pump; an electromagnetic valve which switches between allowing and denying the movement of a cleaning liquid; a cleaner control unit; and a plurality of protection determination units that protect the electromagnetic valve from being supplied with an overcurrent when the electromagnetic valve has short-circuited and is opened, and that notify the cleaner control unit that the electromagnetic valve has short-circuited and is opened. The cleaner control unit outputs, to a vehicle control unit, which electromagnetic valve is unavailable for use, on the basis of a signal that is acquired from the protection determination units and that indicates that the electromagnetic valve has short-circuited and is opened.
