A nozzle in a vehicle includes a nozzle insert to provide pulsed flow of a cleaning agent from an outlet to clean a sensor of the vehicle. The nozzle also includes a cleaning agent supply line to provide the cleaning agent to an inlet of the nozzle insert.

A device for distributing washer fluid includes a cover portion into which a washer fluid is introduced, a moving shaft assembly located inside the cover portion, a motor assembly located at one end of the moving shaft assembly and configured to rotate the moving shaft assembly, one or more flow holes located in the moving shaft assembly, a plurality of distribution units located to correspond to the one or more flow holes, and a controller configured to control a rotation amount of the motor assembly which is configured to selectively discharge an washer fluid introduced into the one or more flow holes to the plurality of distribution units.

The invention relates to a valve block (10) for use in supplying cleaning medium to a plurality of consumers. The invention further relates to a method for supplying cleaning medium and to a use of a valve block (10). The valve block (10) according to the invention comprises at least one cleaning medium supply connection (22), a plurality of switching valves (24, 26) connected to the at least one cleaning medium supply connection (22), a control unit (14) which is configured to control the switching valves (24, 26) in an alternating manner individually and/or several of the switching valves (24, 26) simultaneously, and a position detection unit which is configured to determine the switching position of at least one switching valve (24, 26) without a sensor.

A fluid apparatus includes a straight pipe; an inlet fluidly connected to the pipe; a first cylindrical tube, a second cylindrical tube, and a third cylindrical tube each fluidly connected to and elongated from the pipe; a first solenoid valve controlling flow through the first cylindrical tube; a second solenoid valve controlling flow through the second cylindrical tube; a third solenoid valve controlling flow through the third cylindrical tube; a first outlet fluidly connected only to the first solenoid valve; and a second outlet fluidly connected only to the second solenoid valve and the third solenoid valve.

In an embodiment a washer system includes a plurality of measurement units configured to receive data required for vehicle driving, a nozzle configured to provide a washer fluid to the measurement units, a main reservoir configured to store the washer fluid, a sub-reservoir coupled to at least one of the measurement units and configured to be supplemented with the washer fluid from the main reservoir and a controller configured to determine a priority of the measurement units and supply, in response to the priority of the measurement units, the washer fluid from the main reservoir to the sub-reservoir based on the measurement unit having a higher priority.

A sensor surface cleaning apparatus for a vehicle includes at least one sensor or camera, at least one cleaning unit for jetting a cleaning liquid toward a sensor surface of the sensor or camera, and a travel control ECU which operates in accordance with its operation mode switchable between a first mode in which automatic cleaning operation is permitted and a second mode in which the automatic cleaning operation is not permitted. In a period during which the operation mode is the first mode, the travel control ECU switches the operation mode to the second mode upon satisfaction of at least one of a first particular condition showing an environment in which the sensor surface easily becomes dirty and a second particular condition showing that dirt on the sensor surface cannot be removed by the cleaning liquid.

The present teaching relates to method, system, and implementations for glare control. A sensor housing assembly is provided on an autonomous vehicle to house at least one sensor therein and protect the at least one sensor from negative impact from an environment including glare from the environment that prevents the at least one sensor from capturing accurate information regarding a field of view with respect to the environment to facilitate autonomous driving of the autonomous vehicle. The negative impact on the at least one sensor is determined by a controller, which then activates a glare blocking mechanism in response to the determined negative impact. The glare blocking mechanism being mounted on the sensor housing assembly and configured to assist in blocking glare with respect to the at least one sensor.

Aspects of the disclosure relate to cleaning rotating sensors having a sensor housing with a sensor input surface. For instance, a first signal indicating that there is a contaminant on the sensor input surface may be received. In response to receiving the first signal, a second signal may be sent in order to cause one or more transducers to generate waves in order to attempt to remove the contaminant from the sensor input surface.

A pump chamber (32a), valve chambers (33a and 33b), discharge holes (33e and 33f), and flow paths (34 and 35) are integrally provided to each other in a housing (30), so that the pressure loss of the cleaning liquid “W” can be reduced. In addition, since valve chambers of the flow paths extend to the discharge holes, the cleaning liquid flowing out of the flow paths can be discharged at a portion closer to the central of the valve chambers. As a result, the outlet portions of the flow paths and the inlet portions of the discharge holes is brought closer to each other, and the turbulent of the cleaning liquid in the valve chambers can be suppressed, thereby reducing the pressure loss.

An assembly includes an inlet tube. The assembly includes a first outlet tube. The assembly includes a solenoid assembly having a plunger movable between an open position in which fluid is permitted to flow from the inlet tube to the outlet tube and a closed position in which fluid is inhibited from flowing from the inlet tube to the outlet tube. The solenoid assembly has a spring urging the plunger to the closed position. The solenoid assembly has a strain gage fixed to the spring. A strain detected by the strain gage indicates whether the plunger is at the closed position.
