A heating element of the system is configured to apply heat to the distributor and a controller is configured to operate the heating element when a preset condition is satisfied.

Disclosed is a cleaning solution supply device, and more particularly, a cleaning solution supply device for a fuel cell vehicle. The cleaning solution supply device includes a housing, a mixing pump mounted on the housing and configured to receive water generated during power generation by a fuel cell stack and to mix the received water with a cleaning agent stored in the housing, and a supply line configured to discharge a cleaning solution obtained by mixing the received water with the cleaning agent to an outside of the housing.

Methods, systems and computer readable program products for maintaining windscreen visibility using surface monitoring are disclosed. In embodiments, the system comprises a set of sensors for monitoring a state of a windscreen surface and for generating one or more signals representing that state; a control system for analyzing the one or more signals to identify defined conditions of the surface of the windscreen and to generate one or more control signals; and a set of activatable devices for receiving the one or more control signals. The control signals activate the activatable devices to remove the identified conditions of the surface of the windscreen. In embodiments, the set of activatable devices includes air jets and cleaning fluid jets, and the control signals activate these jets to direct air and cleaning fluids onto the windscreen. This may be done to remove rain drops or dirt from the windscreen.

A sensor apparatus includes a housing attachable to a vehicle and including a panel, a sensor window, a liquid nozzle fixed relative to the housing, and a tunnel. The panel includes a port. The sensor window is positioned in the port. The liquid nozzle is aimed at the sensor window. The liquid nozzle is positioned in a first horizontal direction from the port along the panel. The tunnel extends along the panel and is positioned in a second horizontal direction from the port, the second horizontal direction being opposite the first horizontal direction. The tunnel terminates at an opening positioned to receive fluid outputted by the nozzle.

Devices, systems, and methods are provided for enhanced sensor cleaning validation. A device may determine a baseline performance measurement associated with a clean performance baseline of a sensor. The device may actuate a cleaning mechanism to remove at least a portion of an obstruction deposited on the sensor. The device may determine a first post-clean performance measurement associated with the sensor. The device may determine a degradation measurement between the baseline performance measurement and the first post-clean performance measurement, wherein the degradation measurement indicates an effectiveness of the cleaning mechanism.

Systems and methods for cleaning vehicle sensors are disclosed that optimize sensor cleaning fluid usage. An exemplary vehicle sensor cleaning system includes a sensor cleaning fluid delivery system that delivers sensor cleaning fluid to a sensor of a vehicle and a sensor cleaning control system in communication with the sensor cleaning fluid delivery system. The sensor cleaning control system determines a target cleanliness level for the sensor based on sensor cleaning data associated with the sensor. The target cleanliness level is less than a maximum cleanliness level indicating indicates a contaminate-free sensor. The sensor cleaning control system further monitors a cleanliness level of the sensor and initiates a sensor cleaning operation when the cleanliness level of the sensor is less than an operational cleanliness threshold, such that the sensor cleaning fluid delivery system delivers sensor cleaning fluid to the sensor to clean the sensor to the target cleanliness level.

A vehicle cleaner system includes: a window washer configured to clean a front window of a vehicle; a lamp cleaner configured to clean a headlamp; a sensor cleaner configured to clean a sensor that detects information outside the vehicle; and a cleaner control unit configured to operate at least one of the window washer, the lamp cleaner, and the sensor cleaner in accordance with input of a signal. The cleaner control unit is configured to operate the window washer, the lamp cleaner, and the sensor cleaner such that at least two or more of a number of operations of the window washer, a number of operations of the lamp cleaner, and a number of operations of the sensor cleaner are different in accordance with a predetermined number of signals.

There is provided a delivery unit for a cleaning system and a method of operation. The delivery unit has a liquid nozzle for delivering a liquid jet and directing the liquid jet towards a surface of a sensor system, an air nozzle for delivering an air jet and directing the air jet towards the surface of the sensor system, and a deflection orifice for delivering an other air jet for deflecting the liquid jet away from the air nozzle. The liquid nozzle is located proximate to the air nozzle. The air nozzle and the deflection orifice are in fluid communication with a single air manifold.

A rainwater collection system is provided for a motor vehicle. That rainwater collection system includes a rainwater collector, a gate for the rainwater collector and a controller. The controller is configured to open and close the gate in response to data input respecting the occurrence of precipitation, a level of windshield washer fluid in a windshield washer system of the motor vehicle and in accordance with other monitored parameters including motor vehicle speed and battery voltage level. A related method is also disclosed.

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 having an induction coil surrounding the plunger. The assembly includes a Hall effect sensor that detects a magnetic field of the solenoid assembly. The assembly includes a computer in communication with the Hall effect sensor, the computer having a processor and memory that stores instructions executable by the processor to identify a resistance of the induction coil based on data from the Hall effect sensor, and to determine whether the plunger is at the closed position based on the identified resistance of the induction coil.
