Abstract: 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.

Abstract: A vehicular air curtain device configured to send continuously, based on an operation signal, air to a sensor or a sensor cover mounted on a vehicle at a predetermined wind speed or a predetermined air flow rate in order to prevent dirt from adhering to the sensor or the sensor cover, the vehicular air curtain device includes: an air blowing mechanism; a motor configured to drive the air blowing mechanism; and an air curtain control unit configured to change a drive voltage or a drive current of the motor in accordance with a predetermined condition.

Abstract: A vehicle cleaner system according to the present invention includes: cleaner units that eject cleaning fluid to on-vehicle objects to be cleaned; motor pumps that supply the cleaning fluid to the cleaner units; normally closed solenoid valves provided between the cleaner units and the motor pumps to switch between allowance and disallowance of the transfer of the cleaning fluid from the motor pumps to the cleaner units; and a cleaner control unit that controls the motor pumps and the solenoid valves. The cleaner control unit sets an operation stop time t2, for which at least one of a motor pump and a solenoid valve is stopped, and stops, on the basis of a predetermined condition, the operation of the at least one of the motor pump and the solenoid valve for the duration of the operation stop time t2 after the cleaning fluid is ejected to the object to be cleaned.

Abstract: 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.

Abstract: 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.

Abstract: 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.
