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.

Assembly for sensor cleaning with solenoid

An assembly includes an inlet tube and an 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 assembly includes a first pressure sensor positioned to be compressed when the plunger is moved toward the open position. Pressure detected by the first pressure sensor indicates whether the plunger is at the open position. The assembly includes a second pressure sensor positioned to be compressed when the plunger is moved toward the closed position. Pressure detected by the second pressure sensor indicates whether the plunger is at the closed position.

A windshield window wiping system, including a wiper blade in contact with a windshield window; a wiper motor operatively connected to the wiper blade, configured to perform a wiper blade stroke; a reservoir for a wash fluid; a first hood mounted nozzle, configured to project the wash fluid toward the windshield window; a wash pump, wherein the wash pump is hydraulically connected to the first hood mounted nozzle; and a first electronic circuit, configured to estimate a position of the wiper blade during the wiper blade stroke based on an input to the first electronic circuit and to synchronize the projection of the wash fluid toward the windshield window with the estimated position of the wiper blade. In other aspects, a method of wiping a windshield window and a non-transitory computer readable medium are provided.

Wash pump control based on predicted wiper arm position using hood mounted spray nozzles

A windshield window wiping system, including a wiper blade in contact with a windshield window; a wiper motor operatively connected to the wiper blade, configured to perform a wiper blade stroke; a reservoir for a wash fluid; a first plurality of holes on a first leading edge of the wiper blade, configured to project the wash fluid toward the windshield window; a wash pump, wherein the wash pump is hydraulically connected to the first plurality of holes; and a first electronic circuit, configured to estimate a position of the wiper blade during the wiper blade stroke based on an input to the first electronic circuit and to synchronize the projection of the wash fluid toward the windshield window with the estimated position of the wiper blade. In other aspects, a method of wiping a windshield window and a non-transitory computer readable medium are provided.
