Example one

Fig. 1 is a schematic structural diagram of a vehicle environment sensing component cleaning system according to an embodiment of the present invention, which is applicable to a situation of cleaning an environment sensing component on a running vehicle, where the environment sensing component refers to a component capable of sensing a surrounding environment, such as a vehicle-mounted camera and a radar, and the vehicle-mounted camera may be a back-up rear-view camera, a panoramic parking camera, and the like. As shown in fig. 1, the vehicle environment sensing part cleaning system includes a common rail module 1, a nozzle 2, an air supply module 3, a liquid supply module 4, and a control module 5.

A common rail cavity is arranged in the common rail module 1, and the common rail cavity is provided with a liquid inlet path 11, a gas inlet path 12, a gas outlet path 13 and a liquid outlet path 14; the liquid supply module 4 is communicated with the liquid inlet path 11, and the gas supply module 3 is communicated with the gas inlet path 12. The liquid inlet path 11 is a path of a common rail cavity for inlet liquid, the gas inlet path 12 is a path of a common rail cavity for inlet gas, the gas outlet path 13 is a path of a common rail cavity for outlet gas, and the liquid outlet path 14 is a path of a common rail cavity for outlet liquid. The liquid supply module 4 is a module capable of conveying liquid, and the liquid supply module 4 is communicated with the liquid inlet path 11, so that the liquid supply module 4 can convey liquid to the common rail cavity through the liquid inlet path 11. The gas supply module 3 is a module capable of supplying gas, and the gas supply module 3 communicates with the gas inlet path 12, so that gas can be supplied to the common rail chamber through the gas inlet path 12.

The common rail module 1 comprises a switch sub-module 15, and the switch sub-module 15 is used for controlling the liquid inlet, the gas inlet, the liquid outlet and the gas outlet of the liquid inlet path 11, the gas inlet path 12, the gas outlet path 13 and the liquid outlet path 14. The switch sub-module 15 is a module capable of controlling the on/off of the passage, for example, when the liquid inlet 11 is open, liquid can enter the common rail cavity through the liquid inlet 11, but when the liquid inlet 11 is closed, liquid cannot enter the common rail cavity through the liquid inlet 11. Because, through the switch submodule 15, the liquid inlet, the gas inlet, the liquid outlet and the gas outlet of the liquid inlet path 11, the gas inlet path 12, the gas outlet path 13 and the liquid outlet path 14 can be controlled.

The liquid feeding process can be performed again when the common rail cavity is filled with gas, so that the common rail cavity is switched from gas to liquid. Liquid or gas can be stored in the common rail cavity by controlling the on and off of different passages and controlling the liquid supply and gas supply of the liquid supply module 4 and the gas supply module 3, and the control method can be various and is not described in detail herein.

Since both the gas outlet channel 13 and the liquid outlet channel 14 are communicated with the nozzle 2, when the common rail cavity is filled with liquid, the liquid can be sprayed out from the nozzle 2 through the gas outlet channel 14, but when the common rail cavity is filled with gas, the gas can be sprayed out from the nozzle 2 through the gas outlet channel 13, so that the nozzle 2 can sequentially spray the liquid and the gas in the common rail cavity to the environment sensing part for cleaning. The structure of nozzle 2 can be multiple, for example be equipped with hydrojet and air jet on nozzle 2, hydrojet intercommunication has the inlet to connect, goes out liquid way 14 and inlet and connects the intercommunication, and the air jet rear end is connected with the air feed interface, and air outlet 13 and air feed interface intercommunication to nozzle 2 can wash rethread air jet behind the environmental perception part through hydrojet of hydrojet to weather the environmental perception part. Meanwhile, the nozzle 2 can be provided with a spray hole which is communicated with a hole inlet connector, and the liquid outlet path 14 and the gas outlet path 13 are both communicated with the hole inlet connector, so that the nozzle 2 can spray liquid through the spray hole to wash the environment sensing component and then blow the environment sensing component through the spray hole.

Above-mentioned scheme, through setting up common rail module 1, nozzle 2, gas supply module 3, supply liquid module 4 and control module 5, control module 5 can make common rail module 1's common rail chamber switch in liquid and gas, thereby nozzle 2 can be under different situation or different time blowout liquid and gas, thereby can be at the vehicle in-process of traveling, clean environment perception part blowout liquid earlier, then blow-dry environment perception part blowout gas, prevent that remaining moisture from disturbing the perception of environment perception part to the environment, the inconvenient environment perception part of cleaning in the automobile driving process has been solved, the problem of the safety of traveling of vehicle is easily influenced, the security of vehicle driving in-process has been improved.

The multiple times are different times after the common rail cavity is closed, such as the pressure of the common rail cavity at the first second, the second and the third second after the common rail cavity is closed, and at 3 times.

Determining whether or not the fluctuation of the pressure information of the common rail chamber detected by the first pressure detecting member at a plurality of times exceeds a preset fluctuation value. The preset floating value refers to a value which is smaller than the floating value of the pressure information monitored at different moments when the common rail cavity is airtight.

If yes, determining that air leakage fault occurs and outputting fault information. When the common rail cavity is airtight, the common rail cavity is in a closed state, so that the pressure difference value inside the common rail cavity at different moments is small, namely the floating is small, and therefore when the floating of the pressure information of the common rail cavity detected by the first pressure detection part at multiple moments exceeds a preset floating value, the phenomenon that the common rail cavity is prone to air leakage is indicated, and therefore air leakage fault is determined to be generated at the moment and fault information is output. The fault information is information reflecting the occurrence of the air leakage phenomenon, and a user can know the fault condition of the cleaning system by acquiring the fault information, so that the fault information is convenient to process in time.

If not, the self-checking is normal.

Meanwhile, system information can be output in different modes, so that a user can know the condition of the cleaning system of the vehicle environment sensing component in time.

and acquiring the perception information of the environment perception part.

Determining whether the perception information satisfies a preset cleaning rule.

If yes, a cleaning instruction is generated.

The sensing information refers to information related to an external environment acquired by the environment sensing component, for example, when the environment sensing component is a camera, the sensing information may be image information acquired by the camera, that is, camera image information. The preset cleaning rule is a rule which is satisfied by the sensing information when the environment sensing part needs to be cleaned. Through the mode, the environment sensing component can be automatically cleaned when the environment sensing component needs to be cleaned, and the use is convenient.

On the basis of the above embodiment, the perception information includes camera image information.

The determining whether the perception information satisfies a preset cleaning rule includes:

and carrying out graying processing on the image information of the camera.

And determining whether the average gray scale of the image information of the camera is larger than a preset gray scale value.

The graying process means that the image cannot see color information, each pixel point only has one corresponding gray value, when the lens of the camera is blocked due to dirt, the gray value of the blocked pixel value is increased, therefore, an averaging process can be carried out, and when the average gray value is larger than a preset gray value, the state which needs to be cleaned is defined. Therefore, whether cleaning is needed or not can be known by determining whether the average gray scale of the image information of the camera is larger than a preset gray scale value or not. In a specific embodiment, the preset gray level is 153, and when the average gray level is greater than or equal to 153 (i.e. the blocked rate is greater than or equal to 20%), the state is defined as a state requiring cleaning, and when the average gray level is less than or equal to 128%, the state is understood as a clean state.
