Description

Technical Field

[0001] This invention relates to the field of vehicle technology, and more particularly to a method, apparatus, vehicle, and storage medium for replenishing windshield washer fluid. Background Technology

[0002] Over time, the windshield of a car inevitably becomes dirty, affecting the driver's visibility and posing a safety hazard. Therefore, vehicles are usually equipped with a windshield washer fluid reservoir and a spray system. When the windshield needs cleaning, the spray system draws fluid from the reservoir and sprays it onto the windshield, which is then cleaned by the wipers.

[0003] After a period of vehicle use, the windshield washer fluid in the reservoir will be depleted, requiring the owner to manually refill it. For owners with small reservoirs and frequent use, this means more frequent refills, impacting the user experience. Summary of the Invention

[0004] This invention provides a method, apparatus, vehicle, and storage medium for replenishing windshield washer fluid to achieve automatic replenishment.

[0005] In a first aspect, embodiments of the present invention provide a windshield washer fluid replenishment method, applied to a windshield washer fluid replenishment system comprising a collection device, a windshield washer fluid storage tank, a cleaning agent storage tank, a first pipe connecting the collection device and the windshield washer fluid storage tank, a second pipe connecting the cleaning agent storage tank and the windshield washer fluid storage tank, a first valve disposed on the first pipe, a second valve disposed on the second pipe, and a controller, the method comprising:

[0006] After confirming that the windshield washer fluid replenishment system is turned on, determine the liquid level in the windshield washer fluid storage tank;

[0007] If the liquid level is determined to be lower than the first limit, the first valve is opened and the liquid is discharged into the glass water storage tank through the first pipe after the liquid collection device collects the liquid.

[0008] When the liquid level is stable and the increase in liquid amount is greater than the preset amount, the second valve is opened, and a cleaning agent dose matching the increase in liquid amount is discharged into the glass water storage tank through the second pipe.

[0009] The technical solution of this invention provides a windshield washer fluid replenishment method, applied to a windshield washer fluid replenishment system including a collection device, a windshield washer fluid storage tank, a cleaning agent storage tank, a first pipe connecting the collection device and the windshield washer fluid storage tank, a second pipe connecting the cleaning agent storage tank and the windshield washer fluid storage tank, a first valve disposed on the first pipe, a second valve disposed on the second pipe, and a controller. The method includes: determining the liquid level in the windshield washer fluid storage tank after the windshield washer fluid replenishment system is turned on; if the liquid level is determined to be lower than a first limit, controlling the opening of the first valve, and after the collection device collects liquid, draining the liquid into the windshield washer fluid storage tank through the first pipe; if the liquid level is determined to be stable and the liquid increase is greater than a preset amount, controlling the opening of the second valve, and draining a dosage of cleaning agent matching the liquid increase into the windshield washer fluid storage tank through the second pipe. The above technical solution, when the windshield washer fluid replenishment system is activated, monitors the liquid level in the windshield washer fluid reservoir. If the liquid level is found to be below a first limit, windshield washer fluid replenishment is required. At this time, the first valve can be opened to open the first pipeline between the liquid collection device and the windshield washer fluid reservoir. After the liquid collection device collects the liquid, it is discharged into the windshield washer fluid reservoir through the first pipeline, thus replenishing the liquid in the reservoir. Of course, when the liquid level is stable and the liquid increase is greater than a preset amount, the liquid collection device can open the second valve to open the second pipeline between the cleaning agent storage tank and the windshield washer fluid reservoir. The cleaning agent, with a dosage matching the liquid increase, is discharged into the windshield washer fluid reservoir through the second pipeline, thus replenishing the cleaning agent in the reservoir. The liquid and cleaning agent in the reservoir are thoroughly mixed to obtain the required concentration of windshield washer fluid. Therefore, the replenishment of windshield washer fluid in the reservoir can be achieved.

[0010] Furthermore, the windshield washer fluid replenishment system also includes a liquid level monitoring device installed inside the windshield washer fluid storage tank, which determines the liquid level in the windshield washer fluid storage tank by:

[0011] The liquid level in the glass water storage tank is determined based on the liquid level monitoring device.

[0012] Furthermore, after the liquid is discharged into the glass water storage tank through the first pipe, the method further includes:

[0013] If the liquid level does not change within a preset time, the liquid level is determined to be stable.

[0014] The amount of liquid increase is determined based on the first liquid level height before the liquid is discharged from the glass water storage tank and the second liquid level height after the liquid level stabilizes.

[0015] Furthermore, after the liquid is discharged into the glass water storage tank through the first pipe, the method further includes:

[0016] If the liquid level is determined to be higher than the second limit, the first valve is controlled to be closed, wherein the second limit is greater than the first limit.

[0017] Furthermore, when it is determined that the liquid level is stable and the increase in liquid amount is greater than a preset amount, the following steps are also included:

[0018] Based on the increase in liquid volume and the ratio of liquid to detergent dosage, determine the detergent dosage that matches the increase in liquid volume.

[0019] Furthermore, it also includes:

[0020] Upon receiving the activation message, the windshield washer fluid replenishment system is activated.

[0021] Furthermore, the liquid collection device is located at the bottom of the vehicle's windshield to collect liquid that slides down from the windshield; the first valve is a three-way valve, which, when the first valve is opened, opens the first pipe while simultaneously closing the drain channel of the liquid collection device to the drain outlet.

[0022] In a second aspect, embodiments of the present invention also provide a windshield washer fluid replenishment device, configured in any of the windshield washer fluid replenishment systems described in the first aspect, comprising:

[0023] The determination module is used to determine the liquid level in the windshield washer fluid storage tank after the windshield washer fluid replenishment system is turned on.

[0024] The first opening module is used to control the opening of the first valve when it is determined that the liquid level is lower than the first limit, and to discharge the liquid into the glass water storage tank through the first pipe after the liquid collection device collects the liquid.

[0025] The second opening module is used to control the opening of the second valve after the liquid level is determined to be stable, and to discharge a cleaning agent with a dosage matching the increase in liquid into the glass water storage tank through the second pipe.

[0048] In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0049] Figure 1 This is a flowchart illustrating a windshield washer fluid replenishment method provided in an embodiment of the present invention. This embodiment is applicable to situations requiring automatic windshield washer fluid replenishment. The method is applied to... Figure 2 The windshield washer fluid replenishment system shown is as follows: Figure 2 As shown, the windshield washer fluid replenishment system is communicatively connected to the vehicle's interaction module. The system includes a collection device, a windshield washer fluid reservoir, a detergent storage tank, a first pipe connecting the collection device and the reservoir, a second pipe connecting the detergent storage tank and the reservoir, a first valve on the first pipe, a second valve on the second pipe, and a controller. This method can be executed by the windshield washer fluid replenishment device. Figure 1 As shown, the specific steps include the following:

[0050] Step 110: After confirming that the windshield washer fluid replenishment system is turned on, determine the liquid level in the windshield washer fluid storage tank.

[0051] The vehicle's interactive module has a switch button for the windshield washer fluid replenishment system. Users can turn the windshield washer fluid replenishment system on and off by clicking the switch button on the interactive module.

[0052] Specifically, after clicking the switch button for the windshield washer fluid replenishment system via the interactive module, the user can activate the system and begin monitoring the fluid level in the reservoir. The reservoir is equipped with a fluid level monitoring device, which allows the user to determine the fluid level within the reservoir.

[0053] In practical applications, when users manually add windshield washer fluid, to prevent the vehicle from automatically adding detergent to the windshield washer fluid reservoir that has already been manually filled, the windshield washer fluid replenishment system can be turned off, and then turned back on after confirming that the manual addition is complete. When users wash their cars, to prevent a large amount of liquid containing car detergent from flowing down the windshield into the windshield washer fluid reservoir, the windshield washer fluid replenishment system can also be turned off, and then turned back on after confirming that the car wash is complete.

[0054] It should be noted that when the windshield washer fluid replenishment system is shut down, both the first and second valves remain closed.

[0055] In this embodiment of the invention, when it is determined that the windshield washer fluid replenishment system is to be turned on, the monitoring of the liquid level in the windshield washer fluid reservoir is activated.

[0056] Step 120: If the liquid level is determined to be lower than the first limit, control the opening of the first valve, and after the liquid is collected by the liquid collection device, discharge the liquid into the glass water storage tank through the first pipe.

[0057] The liquid collection device can be a collection tray or a collection trough, used to collect liquids that slide down the windshield. These liquids include rainwater and windshield washer fluid sprayed onto the windshield. If the fluid level in the windshield washer fluid reservoir is above a first limit, it indicates that no replenishment is needed. If the fluid level is below a second limit, it indicates that replenishment is necessary. In this case, windshield washer fluid can be added until the fluid level is above the first limit.

[0058] Specifically, when the liquid level is determined to be below a first limit, it is determined that windshield washer fluid needs to be replenished in the reservoir. Therefore, liquid and a cleaning agent of a corresponding dosage can be added to the reservoir. Specifically, when the liquid level is determined to be below the first limit, the windshield washer fluid needs to be replenished by collecting liquid through a collection device. The collection device and the windshield washer fluid reservoir are connected by a first pipe equipped with a first valve. Therefore, the first valve can be opened to open the first pipe between the collection device and the windshield washer fluid reservoir. After the collection device collects the liquid, it is discharged into the windshield washer fluid reservoir through the first pipe.

[0059] It should be noted that the first valve can be a three-way valve. When the first valve is opened, the first pipe is opened and the drainage channel from the liquid collection device to the drain port is closed at the same time. When the first valve is closed, the drainage channel from the liquid collection device to the drain port is opened and the first channel is closed at the same time. That is, when the first valve is closed, after the liquid collection device collects liquid, the liquid can be discharged through the drain port, avoiding the problem of vehicle dirt caused by long-term accumulation of liquid in the liquid collection device.

[0060] Understandably, during the process of discharging the liquid collected by the liquid collection device into the windshield washer fluid storage tank through the first pipe, the liquid level can be monitored in real time. If it is determined that the liquid level is higher than the second limit, it is determined that there is a risk of windshield washer fluid overflowing into the windshield washer fluid storage tank. At this time, the first valve can be closed to shut off the first channel and stop discharging liquid into the windshield washer fluid storage tank.

[0061] Since a corresponding amount of cleaning agent needs to be added after replenishing the windshield washer fluid reservoir, the initial height of the reservoir can be recorded before replenishing and the final height after replenishing. The amount of fluid added can then be determined based on the height difference between the final and initial heights.

[0062] In this embodiment of the invention, when it is determined that the liquid level in the glass water storage tank is lower than a first limit, the first pipe between the liquid collecting device and the glass water storage tank is opened by controlling the opening of the first valve. After the liquid collecting device collects the liquid, it discharges the liquid into the glass water storage tank through the first pipe, thereby replenishing the liquid in the glass water storage tank.

[0063] Step 130: When it is determined that the liquid level is stable and the liquid increase is greater than the preset amount, the second valve is opened and the cleaning agent with a dosage matching the liquid increase is discharged into the glass water storage tank through the second pipe.

[0064] The stable liquid level can be understood as the liquid no longer increasing. This cessation of liquid increase could be due to the closure of the first valve or the cessation of liquid sliding from the windshield to the collection device.

[0065] Specifically, when the increase in liquid level is no greater than the preset amount, the concentration of the windshield washer fluid has little impact, and no additional cleaning agent needs to be added. Therefore, after confirming that the liquid level is stable, the increase in liquid level can be compared with the preset amount. If the increase in liquid level is greater than the preset amount, the cleaning agent dosage can be determined based on the increase in liquid level and the dosage ratio of liquid to cleaning agent. Then, cleaning agent can be added to the windshield washer fluid reservoir. The cleaning agent is stored in a cleaning agent storage tank, which is connected to the windshield washer fluid reservoir via a second pipe equipped with a second valve. Therefore, the second valve can be opened to open the second pipe between the cleaning agent storage tank and the windshield washer fluid reservoir, allowing the cleaning agent dosage matching the increase in liquid level to be discharged from the cleaning agent storage tank into the windshield washer fluid reservoir through the second pipe. It should be noted that the specific value of the preset amount can be set according to actual needs and is not specifically limited here.

[0066] In this embodiment of the invention, after determining that the liquid level is stable and the liquid increase is greater than a preset amount, the second valve is opened to open the second pipeline between the cleaning agent storage tank and the windshield washer fluid reservoir. The cleaning agent with a dosage matching the liquid increase is discharged into the windshield washer fluid reservoir through the second pipeline to replenish the cleaning agent in the windshield washer fluid reservoir. The liquid and cleaning agent added to the windshield washer fluid reservoir are fully mixed to obtain the required concentration of windshield washer fluid, thus replenishing the windshield washer fluid in the windshield washer fluid reservoir.

[0067] The windshield washer fluid replenishment method provided in this invention includes: a windshield washer fluid replenishment system comprising a collection device, a windshield washer fluid storage tank, a cleaning agent storage tank, a first pipe connecting the collection device and the windshield washer fluid storage tank, a second pipe connecting the cleaning agent storage tank and the windshield washer fluid storage tank, a first valve disposed on the first pipe, a second valve disposed on the second pipe, and a controller. The method includes: determining the liquid level in the windshield washer fluid storage tank after the windshield washer fluid replenishment system is turned on; if the liquid level is determined to be lower than a first limit, controlling the opening of the first valve, and after the collection device collects liquid, discharging the liquid into the windshield washer fluid storage tank through the first pipe; and if the liquid level is determined to be stable and the liquid increase is greater than a preset amount, controlling the opening of the second valve, and discharging a cleaning agent dose matching the liquid increase into the windshield washer fluid storage tank through the second pipe. The above technical solution, when the windshield washer fluid replenishment system is activated, monitors the liquid level in the windshield washer fluid reservoir. If the liquid level is found to be below the lower limit, replenishment is required. At this point, the first valve is opened to open the first pipe between the liquid collection device and the windshield washer fluid reservoir. After the liquid collection device collects the liquid, it is discharged into the windshield washer fluid reservoir through the first pipe to replenish the liquid in the reservoir. Of course, after the liquid level is stabilized and the liquid in the reservoir no longer increases, if the liquid increase exceeds a preset amount, the second valve is opened to open the second pipe between the cleaning agent storage tank and the windshield washer fluid reservoir. A dosage of cleaning agent matching the liquid increase is discharged into the windshield washer fluid reservoir through the second pipe to replenish the cleaning agent in the reservoir. The liquid and cleaning agent in the reservoir are thoroughly mixed to obtain the required concentration of windshield washer fluid. Therefore, replenishment of windshield washer fluid in the reservoir can be achieved.

[0068] Figure 3 This is a flowchart of another windshield washer fluid replenishment method provided by an embodiment of the present invention. The embodiments of the present invention are also applicable to, for example... Figure 2 The windshield washer fluid replenishment system shown is an embodiment of the present invention, which is a further refinement based on the above embodiments. For example... Figure 3 As shown, in this embodiment of the invention, the method may further include:

[0069] Step 310: After confirming that the windshield washer fluid replenishment system is turned on, determine the liquid level in the windshield washer fluid storage tank.

[0070] In one embodiment, the windshield washer fluid replenishment system further includes a liquid level monitoring device installed in the windshield washer fluid storage tank. Accordingly, step 310 may specifically include:

[0071] Upon receiving the activation information, the windshield washer fluid replenishment system is activated; the fluid level in the windshield washer fluid storage tank is determined based on the fluid level monitoring device.

[0072] The activation information can be sent by the user to the windshield washer fluid replenishment system via the vehicle system's interaction module, or it can be sent by the user to the windshield washer fluid replenishment system via a user terminal that communicates with the vehicle system. The fluid level monitoring device can be a level transmitter.

[0073] Specifically, when the windshield washer fluid replenishment system receives an activation signal, it can activate the entire system and simultaneously activate the liquid level monitoring device installed in the windshield washer fluid reservoir. The liquid level in the reservoir is then determined based on the liquid level monitoring device.

[0074] In this embodiment of the invention, when it is determined that the windshield washer fluid replenishment system is to be turned on, the monitoring of the liquid level in the windshield washer fluid reservoir is activated.

[0075] Step 320: Compare the liquid level height with the first limit value.

[0076] When the windshield washer fluid level is below the first limit, it indicates that windshield washer fluid needs to be replenished. When the level in the windshield washer fluid reservoir is above the second limit, it indicates that windshield washer fluid does not need to be replenished. The specific values ​​of the first and second limits can be set according to actual needs and are not specifically limited here.

[0077] Specifically, the real-time determined liquid level height can be compared with the magnitude of the first limit.

[0078] Step 330: If the liquid level is determined to be lower than the first limit, the first valve is opened and the liquid is discharged into the glass water storage tank through the first pipe after the liquid collection device collects the liquid.

[0079] Specifically, when the liquid level is determined to be below the first limit, the first valve can be opened to open the first pipeline between the liquid collecting device and the glass water storage tank, and after the liquid collecting device collects the liquid, the liquid is discharged into the glass water storage tank through the first pipeline.

[0080] In addition, the windshield washer fluid replenishment system includes a filter installed in the first pipe for filtering the liquid discharged into the windshield washer fluid reservoir through the first pipe. It also includes an inlet located at the top of the windshield washer fluid reservoir for manual replenishment, and an outlet located at the bottom of the reservoir for discharging liquid.

[0081] Step 340: If the liquid level is determined to be higher than the second limit, control the closing of the first valve.

[0082] The second limit is greater than the first limit.

[0083] Specifically, during the process of discharging liquid into the windshield washer fluid storage tank through the first pipe, the liquid level can be monitored in real time. If the liquid level is determined to be higher than the second limit, it is determined that there is a risk of windshield washer fluid overflowing from the storage tank. At this time, the first valve can be closed to shut off the first channel and stop discharging liquid into the windshield washer fluid storage tank.

[0084] Of course, the windshield washer fluid replenishment system remains on, and the fluid level monitoring device continuously monitors the fluid level in the windshield washer fluid reservoir. As the vehicle uses windshield washer fluid, if the fluid level falls below the first limit, the process can return to step 330 to replenish the windshield washer fluid reservoir in a timely manner.

[0085] Figure 4 The diagram showing the relationship between the liquid level in the windshield washer fluid reservoir and the control of the first valve in the windshield washer fluid replenishment method provided in this embodiment of the invention is as follows: Figure 4 As shown, when the liquid level is determined to be lower than the first limit, the first valve is opened, and the liquid is collected by the liquid collecting device to replenish the glass water storage tank until the liquid level is higher than the second limit; when the liquid level is determined to be higher than the second limit, the first valve is closed, and after the liquid collecting device collects the liquid, the liquid is discharged through the drain port.

[0086] In this embodiment of the invention, when the liquid level in the glass water storage tank is determined to be lower than a first limit, the first pipe between the liquid collecting device and the glass water storage tank is opened by controlling the opening of the first valve. After the liquid collecting device collects the liquid, it is discharged into the glass water storage tank through the first pipe, thereby replenishing the liquid in the glass water storage tank. When the liquid level in the glass water storage tank is determined to be higher than a second limit, the first pipe between the liquid collecting device and the glass water storage tank is closed by controlling the closing of the first valve, stopping the discharge of liquid into the glass water storage tank and preventing the glass water storage tank from overflowing. By opening or closing the first valve, automatic control of replenishing the liquid in the glass water storage tank is achieved.

[0087] Step 350: If the liquid level does not change within a preset time, the liquid level is determined to be stable; the amount of liquid increase is determined based on the first liquid level before the liquid is discharged from the glass water storage tank and the second liquid level after the liquid level stabilizes.

[0088] If the liquid level does not change within a preset time, the liquid level can be considered stable. The preset time can be set according to actual needs and is not specifically limited here.

[0089] Specifically, after the liquid level is determined to be stable, the height difference is determined based on the first liquid level height before the liquid is discharged from the glass water storage tank and the second liquid level height after the liquid level is stabilized. Then, the amount of liquid increase is determined based on the height difference and the bottom area of ​​the glass water storage tank.

[0090] Step 360: When it is determined that the increase in liquid is greater than the preset amount, the second valve is opened and the cleaning agent with a dosage matching the increase in liquid is discharged into the glass water storage tank through the second pipe.

[0091] The cleaning agent can be a concentrated liquid cleaning agent or a solid cleaning agent.

[0092] In one embodiment, when it is determined that the increase in liquid amount is greater than a preset amount, the method further includes:

[0093] Based on the increase in liquid volume and the ratio of liquid to detergent dosage, determine the detergent dosage that matches the increase in liquid volume.

[0094] Specifically, when the liquid level is stable and the increase in liquid volume exceeds a preset amount, the required dosage of cleaning agent to match the increased liquid volume is determined. Specifically, the dosage of cleaning agent matching the increase in liquid volume can be determined based on the liquid-to-cleaning agent dosage ratio and the increase in liquid volume. Then, the second valve is opened to open the second pipe between the cleaning agent storage tank and the windshield washer fluid reservoir, allowing the cleaning agent dosage matching the increase in liquid volume from the storage tank to be discharged into the windshield washer fluid reservoir through the second pipe.

[0095] It should be noted that the dosage ratio of liquid to cleaning agent is directly proportional, and the specific ratio can be determined based on the concentration of the cleaning agent.

[0096] Of course, after the appropriate amount of cleaning agent is dispensed into the windshield washer fluid reservoir, the second valve can be closed.

[0097] In addition, to prevent users from adding windshield washer fluid themselves without turning off the automatic windshield washer fluid replenishment system, resulting in the vehicle automatically adding cleaning agent, the following confirmation function is designed: When the level of the windshield washer fluid reservoir is detected to rise rapidly in a short period of time, or when the rate of increase of the fluid exceeds a certain threshold, the user is prompted through an interactive module to confirm whether to add cleaning agent. If the user confirms that cleaning agent should be added, a dosage of cleaning agent matching the amount of fluid added will be added. If the user confirms that they do not want to add cleaning agent or is unsure whether to add it, no cleaning agent needs to be added.

[0098] Since the rate at which the windshield washer fluid reservoir increases when manually added is much greater than the rate at which fluid is added via the first channel, the speed threshold can be set to any value that is greater than the rate at which fluid is added via the first channel and less than the rate at which fluid is added manually. No specific limit is imposed here.

[0099] In this embodiment of the invention, after the liquid is added to the windshield washer fluid reservoir, the second valve is opened to add a matching dose of cleaning agent to the reservoir. The liquid and cleaning agent added to the reservoir are thoroughly mixed to obtain the required concentration of windshield washer fluid, thus replenishing the windshield washer fluid in the reservoir.

[0100] The windshield washer fluid replenishment method provided in this embodiment of the invention includes: a windshield washer fluid replenishment system comprising a collection device, a windshield washer fluid storage tank, a cleaning agent storage tank, a first pipe connecting the collection device and the windshield washer fluid storage tank, a second pipe connecting the cleaning agent storage tank and the windshield washer fluid storage tank, a first valve disposed on the first pipe, a second valve disposed on the second pipe, and a controller. The method includes: determining the fluid level in the windshield washer fluid storage tank after the system is turned on; comparing the fluid level with a first limit; and controlling the system to open when the fluid level is determined to be lower than the first limit. The first valve is opened, and after the liquid is collected by the liquid collection device, the liquid is discharged into the glass cleaner reservoir through the first pipe; if the liquid level is determined to be higher than the second limit, the first valve is closed; if the liquid level is determined not to change within a preset time, the liquid level is determined to be stable; the liquid increase is determined based on the first liquid level before the liquid is discharged into the glass cleaner reservoir and the second liquid level after the liquid level stabilizes; if the liquid increase is determined to be greater than the preset amount, the second valve is opened, and a cleaning agent dose matching the liquid increase is discharged into the glass cleaner reservoir through the second pipe. The above technical solution, when the windshield washer fluid replenishment system is activated, monitors the liquid level in the windshield washer fluid reservoir, comparing it in real time with a first limit. If the liquid level is below the first limit, replenishment is required. In this case, the first valve is opened to connect the first pipe between the collection device and the reservoir. The collection device collects the liquid and discharges it into the reservoir through the first pipe, replenishing the reservoir. If the liquid level is above a second limit, replenishment is not required, and the first valve is closed. By opening and closing the first valve, automatic control of replenishment is achieved. Of course, after the liquid level stabilizes, the system can... The liquid increase is determined based on the first liquid level before liquid is discharged from the windshield washer fluid reservoir and the second liquid level after liquid is discharged. If the liquid increase exceeds the preset amount, the detergent dosage is determined according to the liquid-to-cleaning agent ratio and the liquid increase. This allows for the determination of the detergent dosage based on the liquid increase, which in turn controls the opening of the second valve to open the second pipeline between the detergent storage tank and the windshield washer fluid reservoir. The detergent dosage matching the liquid increase is then discharged into the windshield washer fluid reservoir through the second pipeline, replenishing the detergent in the reservoir. Once the liquid and detergent in the reservoir are fully mixed, the required concentration of windshield washer fluid is obtained. Therefore, the replenishment of windshield washer fluid in the reservoir can be achieved.

[0101] Figure 5This is a schematic diagram of a windshield washer fluid replenishment device provided in an embodiment of the present invention. This device can be configured in any of the windshield washer fluid replenishment systems described in the foregoing embodiments and is suitable for situations requiring automatic replenishment of windshield washer fluid. This device can be implemented through software and / or hardware and is generally integrated into a vehicle.

[0102] like Figure 5 As shown, the device includes:

[0103] The determination module 510 is used to determine the liquid level in the glass fluid storage tank after the glass fluid replenishment system is turned on.

[0104] The first opening module 520 is used to control the opening of the first valve when it is determined that the liquid level is lower than the first limit, and to discharge the liquid into the glass water storage tank through the first pipe after the liquid collection device collects the liquid.

[0105] The second opening module 530 is used to control the opening of the second valve when it is determined that the liquid level is stable and the liquid increase is greater than a preset amount, so that a cleaning agent of a dosage matching the liquid increase is discharged into the glass water storage tank through the second pipe.

[0106] The windshield washer fluid replenishment device provided in this embodiment is configured in a windshield washer fluid replenishment system comprising a collection device, a windshield washer fluid storage tank, a cleaning agent storage tank, a first pipe connecting the collection device and the windshield washer fluid storage tank, a second pipe connecting the cleaning agent storage tank and the windshield washer fluid storage tank, a first valve disposed on the first pipe, a second valve disposed on the second pipe, and a controller. After the windshield washer fluid replenishment system is activated, the liquid level in the windshield washer fluid storage tank is determined. If the liquid level is determined to be lower than a first limit, the first valve is opened, and after the collection device collects liquid, the liquid is discharged into the windshield washer fluid storage tank through the first pipe. If the liquid level is determined to be stable and the liquid increase is greater than a preset amount, the second valve is opened, and a cleaning agent dose matching the liquid increase is discharged into the windshield washer fluid storage tank through the second pipe. The above technical solution, when the windshield washer fluid replenishment system is activated, monitors the liquid level in the windshield washer fluid reservoir. If the liquid level is found to be below a first limit, windshield washer fluid replenishment is required. At this time, the first valve can be opened to open the first pipeline between the liquid collection device and the windshield washer fluid reservoir. After the liquid collection device collects the liquid, it is discharged into the windshield washer fluid reservoir through the first pipeline, thus replenishing the liquid in the reservoir. Of course, when the liquid level is stable and the liquid increase is greater than a preset amount, the liquid collection device can open the second valve to open the second pipeline between the cleaning agent storage tank and the windshield washer fluid reservoir. The cleaning agent, with a dosage matching the liquid increase, is discharged into the windshield washer fluid reservoir through the second pipeline, thus replenishing the cleaning agent in the reservoir. The liquid and cleaning agent in the reservoir are thoroughly mixed to obtain the required concentration of windshield washer fluid. Therefore, the replenishment of windshield washer fluid in the reservoir can be achieved.

[0107] Based on the above embodiments, the windshield washer fluid replenishment system further includes a liquid level monitoring device disposed within the windshield washer fluid storage tank. Correspondingly, the determining module 510 is specifically used for:

[0108] Upon receiving the activation information, the windshield washer fluid replenishment system is activated; the fluid level in the windshield washer fluid storage tank is determined based on the fluid level monitoring device.

[0109] Based on the above embodiments, the device further includes:

[0110] The execution module is used to determine that the liquid level is stable if the liquid level does not change within a preset time; and to determine the amount of liquid increase based on the first liquid level before the liquid is discharged from the glass water storage tank and the second liquid level after the liquid level stabilizes.

[0111] Based on the above embodiments, the first opening module 520 is further configured to:

[0112] If the liquid level is determined to be higher than the second limit, the first valve is controlled to be closed, wherein the second limit is greater than the first limit.

[0113] Based on the above embodiments, the second opening module 530 is further configured to:

[0114] Once it is determined that the liquid level is stable and the liquid increase is greater than a preset amount, a cleaning agent dosage matching the liquid increase is determined based on the liquid increase and the dosage ratio of liquid to cleaning agent.

[0115] Based on the above embodiments, the device further includes:

[0116] The third activation module is used to activate the windshield washer fluid replenishment system upon receiving activation information. Based on the above embodiment, the liquid collection device is located at the bottom of the vehicle's windshield to collect liquid that slides down from the windshield; the first valve is a three-way valve, which, when opened, opens the first pipe while simultaneously closing the drain channel from the liquid collection device to the drain outlet.
