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.

A sensor system equipped with a vehicular cleaner comprising: a sensor configured to operate in a normal mode and a standby mode; a cleaner unit configured to clean the sensor in response to an operation signal output in accordance with a dirt determination result of the sensor; and a control unit configured to control the sensor and the cleaner unit. The sensor is configured to operate in the normal mode, in which the sensor is operated at a predetermined cycle, and in the standby mode, in which the sensor is operated at a cycle longer than in the normal mode. The cleaner unit is configured to operate in a regular mode in which the cleaner unit operates in response to the operation signal and to operate in a block mode in which the cleaner unit does not operate even when the operation signal is input.

Vehicle sensor cleaning systems

A control device that includes a plurality of input ports, each of which receives a binary signal including a first level and a second level, and a setting unit, which sets a numerical value related to control based on the binary signal input to each of the input ports, is disclosed. The input port is configured to be at the second level when a failure occurs, and the setting unit associates different binary signal arrays with a plurality of the numerical values, respectively, and sets a binary signal array corresponding to a numerical value equivalent to a reference value among the plurality of numerical values as an array in which the number of the second level is the largest.

Control device for a vehicle lamp and light distribution control system

A monitoring device includes a comparison unit and a clock control unit. The comparison unit is configured to compare a signal level of a transmission signal and a signal level of a monitoring signal that has received the transmission signal with each other at a timing synchronized with a clock signal. The clock control unit is configured to detect the signal level of the monitoring signal and synchronize the clock signal with a timing when the signal level of the monitoring signal changes.
