Description

Technical Field

[0001] The utility model relates to the technical field of vehicles, in particular to an automobile windshield washer fluid monitoring system. Background Art

[0002] At present, the car windshield washer is a device used to spray washing liquid onto the car glass for cleaning. Ordinary models do not have a liquid level sensor. The function of the liquid level sensor used in high-end vehicles is to alarm when the washing liquid is lower than the limit value in the washing tank to prevent the washing tank from being out of washing liquid. For the windshield cleaning system, the washer storage liquid is the most important function. Vehicles with conventional washers without liquid level sensors cannot identify whether there is glass washing liquid in the washing tank. Only when the windshield washing function is activated can it be known whether there is water in the washing tank. When the vehicle is driving in a dusty environment, the washer The windshield has poor visibility and clarity. If there is no glass washer fluid at this time, it will seriously affect driving safety. High-end B-class car washers are generally equipped with liquid level sensors, but they can only generate alarms when the level is lower than a certain set limit. This cannot meet the user's need to know the amount of washing liquid at any time. This is not conducive to users reasonably arranging the frequency and amount of washing liquid used each time according to the remaining amount of washing liquid, nor is it conducive to users preparing replenishment of washing liquid in advance, reducing user comfort and driving safety. In addition, the current trend of digital control of the whole vehicle is becoming stronger and stronger. The current technology is not conducive to the future integration of the washing system into the digital control system of the whole vehicle.

[0003] Patent CN204177445U proposes a method that can only display four liquid levels: 0, 1 / 4, 2 / 4, and 3 / 4. The display is not accurate. Moreover, since the washers of different models have different upper and lower cross-sectional areas and are placed at different angles, this method cannot simply monitor the remaining height ratio of the washing liquid to accurately display the current remaining amount of washing liquid, and this method cannot display the amount used each time. Utility Model Content

[0004] In order to solve the above problems, the present invention provides a vehicle windshield washer fluid monitoring system, which adopts the following technical solutions:

[0005] A vehicle windshield washer fluid monitoring system includes a washer, and is characterized by further comprising:

[0006] A controller, wherein a memory of the controller is preset with a data table of the current capacity of the scrubber at different liquid levels;

[0007] A liquid level sensor is connected to the signal input terminal of the controller and is used to monitor the liquid level of the washing liquid in the washer;

[0008] A display, connected to the signal output terminal of the controller, for displaying the current washing liquid capacity of the washer and the current washing liquid usage;

[0009] The washing pump is connected to the signal output end of the controller. A washing liquid safety capacity threshold is preset in the memory of the controller. When the current washing liquid capacity of the washer is less than the washing liquid safety capacity threshold, the controller sends a text warning message to the display and displays it.

[0010] Furthermore, it also includes an alarm connected to the signal output end of the controller, and the alarm is an audible and visual alarm. When the current washing liquid capacity of the washer is less than the washing liquid safety capacity threshold, the controller controls the alarm to sound an alarm.

[0011] Furthermore, the signal input terminal of the controller is also connected to the toggle switch signal of the washer for monitoring the state of the toggle switch of the washer.

[0012] The beneficial effects of the present invention are:

[0013] 1. By using a preset liquid level and remaining washer fluid capacity data table, the washer fluid capacity in the washer can be accurately displayed. Compared with the existing solution that only determines whether the washer fluid needs to be replenished based on the liquid level, the technical solution of this application is based on the shape and installation method of the washer of different vehicle models, and the monitoring results are more accurate;

[0014] 2. The controller can calculate the current remaining capacity of the washing fluid and the amount of washing fluid used in the current cycle, and display them on the display, allowing users to understand the above data more intuitively. Moreover, the digital monitoring of the current remaining capacity of the washing fluid and the amount of washing fluid used in the current cycle facilitates access to the vehicle's digital control system.

[0017] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0018] In the description of the utility model, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the viewing direction or position relationship, and are only for the convenience of describing the utility model, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the utility model.

[0019] like Figure 1 The automobile windshield washer fluid monitoring system shown includes a washer, a controller 2, a liquid level sensor 3, an alarm 4 and a display 5. The controller 2 has a preset memory with a washer fluid capacity data table corresponding to the current vehicle washer fluid height. The liquid level sensor 3 is arranged inside the washer and is connected to the signal input end of the controller 2. It is used to monitor the current height of the washer fluid in the washer and transmit the signal to the controller 2. The alarm 4 is an audible and visual alarm. The display 5 is used to display the current remaining capacity of the washer fluid and the amount of washer fluid used in that time. The alarm 4, the washer pump 1 of the washer and the display 5 are all connected to the signal output end of the controller 2, and the controller 2 can monitor the switch state of the washer's toggle switch 6.

[0020] Specifically, a corresponding simulation model is established according to the shape of the washer body, and a capacity data table corresponding to the body at different liquid level heights is obtained through calculus calculation according to the current installation status or tilt angle of the vehicle. The liquid level height-washing liquid capacity data table obtained in the above steps is pre-stored in the memory of the controller 2, and the memory of the controller 2 also has a preset washer liquid safety capacity threshold.

[0021] The working principle of the automobile windshield washer fluid monitoring system is as follows:

[0022] After the controller 2 detects that the toggle switch 6 of the washer is turned on for the first time, the controller 2 records the current washing liquid capacity a and controls the washing pump 1 to start working. The controller 2 obtains the remaining capacity s of the washing liquid in the washer corresponding to the current washing liquid height h according to the preset height-washing liquid remaining capacity data table, and can obtain the current washing liquid usage b=as. The controller 2 sends the current washing liquid usage b and the current washing liquid remaining capacity s to the display 5. When the washing liquid remaining capacity s value is less than or equal to the preset washing liquid safety capacity threshold, the controller 2 controls the alarm 4 to emit an audible and visual alarm signal, and displays a sign indicating insufficient remaining capacity of washing liquid on the display 5. In this embodiment, the display 5 uses a touch screen, and can display or hide the current washing liquid capacity of the washer and the current washing liquid usage data by manual clicking. The sign indicating insufficient remaining capacity of washing liquid cannot be hidden.

[0023] By displaying the current remaining capacity of washer fluid and the current usage amount, this device realizes digital monitoring of washer fluid, more intuitively displays the current vehicle condition, and avoids the problem of being unable to accurately determine the remaining capacity of washer fluid due to only monitoring the washer fluid level under different washer installation methods, compared with traditional methods of reminding that the remaining capacity of washer fluid is too low or simply displaying the percentage of the remaining liquid level.

[0024] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements can be made without departing from the principles of the present invention. These improvements should also be regarded as within the scope of protection of the present invention.
