Description

Control method and device for vehicle windshield cleaning system, electronic equipment and storage medium
Technical Field
The application relates to the technical field of vehicles, in particular to a control method and device for a vehicle windshield cleaning system, electronic equipment and a storage medium.
Background
A vehicle windshield cleaning system is a device for spraying a cleaning liquid onto a windshield of a vehicle, and is generally composed of a liquid storage tank, a water pump, a water pipe, a nozzle and a control device. For cleaning a windshield of a vehicle. As shown in fig. 1, the windshield 1 'is located behind the front hatch 2'. The windshield cleaning system sprays a cleaning liquid through the nozzle 3' to spread on the windshield 1', and then cleans the windshield 1' by a wiper.
In order to secure the cleaning effect, the spraying position of the cleaning liquid sprayed from the nozzle 3' is at the target position 5' so as to be spread as uniformly as possible over the windshield glass 1 '.
However, when the vehicle is traveling at a high speed, the high-speed air flow 4' may affect the washing liquid so that the injection position of the washing liquid injected from the nozzle 3' moves down to the position 6'.
Therefore, in order to cope with the influence of the high-speed air flow 4' on the washing liquid injection at the time of the high-speed running of the vehicle, the washing liquid is ensured to be spread on the windshield glass 1' as uniformly as possible, and the injection pressure to the nozzle 3' is increased in the vehicle windshield cleaning system of the prior art, so that the injection position of the washing liquid injection is restored to the target position 5' at the middle upper portion of the windshield glass 1' at the time of the high-speed running of the vehicle.
However, since the conventional vehicle windshield cleaning system can only provide a single spray pressure at a fixed rotational speed, when the spray pressure of the nozzle 3 'is increased, the spray position of the washing liquid is moved up during low-speed traveling without the influence of the high-speed air flow 4', a large amount of washing liquid is flown away along the a pillars and the roof of the vehicle, resulting in waste of the washing liquid, and the flown-away washing liquid may have an influence on the approaching vehicle and pedestrians.

Detailed Description
Specific embodiments of the present application will be further described below with reference to the accompanying drawings. Wherein like parts are designated by like reference numerals. It should be noted that the words "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to directions in the drawings, and the words "inner" and "outer" refer to directions toward or away from, respectively, the geometric center of a particular component.
A windshield, also called front windshield, is a windshield directly in front of a vehicle. A vehicle windshield cleaning system is a device for spraying a cleaning liquid onto a windshield of a vehicle, and is generally composed of a liquid storage tank, a water pump, a water pipe, a nozzle and a control device. For cleaning a windshield of a vehicle. As shown in fig. 3, the windshield 1 is located behind the front hatch 2. The windshield cleaning system sprays a cleaning liquid through the nozzle 3 to spread on the windshield 1, and then cleans the windshield 1 by a wiper.
In order to secure the cleaning effect, the cleaning liquid discharged from the nozzle 3 needs to be sprayed on the target position 5 so as to be spread on the windshield 1 as uniformly as possible. The target position 5 is a position or area defined by the vehicle manufacturer where the washing liquid is sprayed onto the outer surface of the windshield 1.
However, when the vehicle is traveling at a high speed, the high-speed air flow 4 may exert a pressing effect on the ejection of the washing liquid, so that the ejection position of the washing liquid ejected from the nozzle 3 is moved downward.
Therefore, in order to solve the problem that the high-speed air flow has an influence on the downward pressure of the washing liquid during high-speed running, and in order to avoid the problem that the washing liquid is wasted and influences on nearby vehicles and pedestrians are caused by the fact that the injection position of the washing liquid is too high when the influence of the high-speed air flow is not generated, the application provides a control method of a vehicle windshield cleaning system.
Referring now to FIG. 2, a flow chart of a method for controlling a vehicle windshield cleaning system according to an embodiment of the present application includes:
step S201, obtaining a speed reflecting parameter reflecting the relative speed of the air flow outside the vehicle, wherein the relative speed of the air flow outside the vehicle is the speed of the air flow blown to the window glass of the vehicle relative to the vehicle;
in step S202, if the relative speed of the air flow outside the vehicle reflected by the speed reflection parameter increases, the injection pressure is increased, and if the relative speed of the air flow outside the vehicle reflected by the speed reflection parameter decreases, the injection pressure is decreased.
In particular, embodiments of the present application may be applied to an electronic controller unit (Electronic Control Unit, ECU) of a vehicle. For example, in the control of a vehicle windshield cleaning system.
When the user turns on the vehicle windshield cleaning system, step S201 is performed to acquire a speed reflection parameter reflecting the relative speed of the air flow outside the vehicle. The vehicle running parameter and the vehicle external environment parameter are both relative to the vehicle external air flow so as to reflect the relative speed of the vehicle external air flow. Specifically, the parameter obtained by measuring the relative speed of the air flow outside the vehicle may be a parameter indirectly reflecting the relative speed of the air flow outside the vehicle.
The relative speed of the air flow outside the vehicle refers to the speed of the air flow blown to the window glass of the vehicle relative to the vehicle. For example, as shown in fig. 3, the high-speed air flow 4 is relative to the speed of the vehicle when the vehicle is traveling at a high speed.
In some embodiments, the speed-reflecting parameters include vehicle operating parameters and/or outside-vehicle environment parameters that reflect the relative speed of the outside-vehicle airflow.
Then, step S202 is performed to adjust the injection pressure of the windshield washer system cleaning liquid according to the speed-reflecting parameter. As shown in fig. 3, since the outside air flow may have a pressing effect on the ejection of the washing liquid, the ejection position of the washing liquid ejected from the nozzle 3 is moved downward. Therefore, when the relative speed of the air flow outside the vehicle increases, the injection pressure is increased to oppose the influence of the depression of the air flow outside the vehicle, and when the relative speed of the air flow outside the vehicle decreases, the injection pressure is reduced to avoid upward movement of the injection position of the washing liquid, so that the injection position of the washing liquid is always maintained at the designed target position 5.
In some embodiments, the vehicle windshield cleaning system comprises a liquid storage tank, a water pump, a water pipe, a nozzle and a control device, wherein the input end of the water pump is communicated with the liquid storage tank through the water pipe, the output end of the water pump is communicated with the nozzle through the water pipe, and the control device executes the vehicle windshield cleaning system control method disclosed by the embodiment of the application, controls the working parameters of the water pump and adjusts the injection pressure of the nozzle.
The control device is used for switching on and off the device of the glass cleaning system and adjusting the working parameters of the water pump, such as input voltage and working time. Preferably, the wash liquor is water having a hardness of less than 205g/1000k or an aqueous solution with the addition of suitable amounts of commercial additives.
According to the application, the jet pressure of the washing liquid of the windshield glass cleaning system is regulated by reflecting the speed reflecting parameter of the relative speed of the air flow outside the vehicle, so that the jet pressure of the washing liquid can be adaptively regulated according to the relative speed of the air flow outside the vehicle, and the influence of the air flow on the downward pressure of the washing liquid in the jet process of the washing liquid is adaptively counteracted. Through the self-adaptive adjustment to the washing liquid injection pressure, the relative speed of the air flow outside the vehicle is increased, the injection pressure is increased, the relative speed of the air flow outside the vehicle is reduced, the injection pressure is reduced, the washing liquid injection position is always maintained at the designed target position, the washing liquid use efficiency is improved, and the influence of splashing of the washing liquid on vehicles and pedestrians on two sides and behind is reduced.
FIG. 4 is a flowchart illustrating a method of controlling a vehicle windshield cleaning system according to another embodiment of the present application, comprising:
step S401, obtaining a vehicle speed;
in step S402, if the vehicle speed increases, the injection pressure is increased, and if the vehicle speed decreases, the injection pressure is decreased.
Specifically, the present embodiment executes step S401 to acquire the vehicle speed when the user turns on the vehicle windshield cleaning system.
Since the vehicle moves relatively to the outside air flow when traveling, the air flow blown to the vehicle window glass is fast relative to the vehicle speed when the vehicle speed is fast, and the air flow blown to the vehicle window glass is slow relative to the vehicle speed when the vehicle speed is slow. Therefore, the vehicle speed can indirectly reflect the relative speed of the off-vehicle airflow. Therefore, the vehicle speed is adopted as the vehicle running parameter reflecting the relative speed of the air flow outside the vehicle.
Then, step S402 is performed to increase the injection pressure if the vehicle speed increases, and decrease the injection pressure if the vehicle speed decreases.
In some embodiments, a vehicle windshield cleaning system employs a water pump to spray a cleaning solution.
In one embodiment, if the vehicle speed increases, the injection pressure is increased, and if the vehicle speed decreases, the injection pressure is decreased, specifically including:
if the vehicle speed increases, the input voltage of a water pump of the windshield washer system for injecting the washing liquid is increased, and if the vehicle speed decreases, the input voltage is decreased.
Under the condition of not changing the power of the water pump, the input voltage of the water pump is adjusted by the control device, so that the control of the injection pressure of the washing liquid and the target position is realized: when the vehicle speed is lower, the influence of air flow on washing liquid injection is smaller, and the input voltage of the water pump is reduced through the control device, so that the washing liquid falls at a reasonable target position; with the increase of the vehicle speed, the influence of the air flow on the injection of the washing liquid is gradually increased, and the input voltage of the water pump is increased through the control device, so that the injection pressure of the nozzle is correspondingly increased, and the influence of the air flow on the injection of the washing liquid is counteracted.
In one embodiment, if the vehicle speed increases, the input voltage of the water pump of the windshield cleaning system for spraying the cleaning solution is increased, and if the vehicle speed decreases, the input voltage is decreased, specifically including:
if the vehicle speed is greater than the first vehicle speed threshold value and less than the second vehicle speed threshold value, the input voltage of a water pump of the windshield cleaning system for spraying the cleaning liquid is proportional to the vehicle speed.
In one embodiment, the method further comprises:
if the vehicle speed is smaller than or equal to a first vehicle speed threshold value, the input voltage is kept to be a first voltage value; and if the vehicle speed is greater than or equal to a second vehicle speed threshold value, maintaining the input voltage to be a second voltage value, wherein the second voltage value is greater than the first voltage value.
When the vehicle speed is smaller than or equal to the first vehicle speed threshold value, the vehicle runs at a low speed, and the injection pressure does not need to be increased at the moment, so that the input voltage is kept to be a first voltage value.
When the vehicle speed is greater than the first vehicle speed threshold value and less than the second vehicle speed threshold value, the influence of the air flow on the washing liquid injection is gradually increased, so that the input voltage is gradually increased. Wherein, the vehicle speed is proportional to the input voltage.
In order to avoid an excessive input voltage, the input voltage is maintained at the second voltage value when the vehicle speed is equal to or higher than the second vehicle speed threshold.
In some embodiments, the second voltage value is a maximum voltage value that the water pump is permitted to input, and the second vehicle speed threshold is a vehicle speed value at which the input voltage reaches the second voltage value.
The relation between the input voltage of the water pump and the vehicle speed, namely the voltage-vehicle speed proportionality coefficient, can be obtained through the calibration of a high-speed running test of a specific vehicle type.
In some embodiments, if the vehicle speed is greater than the first vehicle speed threshold and less than the second vehicle speed threshold, a voltage vehicle speed scaling factor is obtained, and the input voltage is calculated as the product of the voltage vehicle speed scaling factor and the vehicle speed.
As shown in the vehicle speed-input voltage relationship curve 51 in fig. 5, assuming that the vehicle type is set to 14V, the control device controls the input voltage of the water pump to be between 10V and 14V, and the vehicle speed is 0 to 20km/h when the vehicle is stationary or running at a low speed, the first vehicle speed threshold is 20km/h, and the water pump voltage is a first voltage value, for example, 10V. At this time, the target position of the washing liquid is controlled at the upper middle portion of the windshield. With the increase of the vehicle speed, the air flow has an influence on the downward pressure of the washing liquid injection, the voltage of the water pump is increased with the increase of the vehicle speed, the injection pressure of the washing liquid is synchronously increased, and the downward pressure influence of the air flow, namely the input voltage V of the water pump, is counteracted Input device ＝k*V Vehicle with a frame Whereink is the voltage and vehicle speed proportional coefficient, V Vehicle with a frame Is the vehicle speed. k can be obtained according to the calibration of a high-speed running test of a specific vehicle type. When the vehicle speed reaches a second vehicle speed threshold, for example 120km/h, the corresponding input voltage is 14V. Therefore, when the vehicle speed is greater than or equal to the second vehicle speed threshold, the input voltage of the water pump is maintained at the second voltage value, namely 14V.
During the running of the vehicle, natural wind in the environment can influence the relative speed of the airflow outside the vehicle in addition to the speed of the vehicle. Thus, the current position wind speed can be combined with the vehicle speed to control the injection pressure. The wind speed at the current position of the vehicle is the wind speed of natural wind at the current position of the vehicle, and the wind direction at the current position of the vehicle is the wind direction of natural wind at the current position of the vehicle. The current position wind speed and the current position wind direction can be obtained from the real-time weather information
In one embodiment, the speed reflecting parameters further include a vehicle running direction, a current position wind speed, and a current position wind direction, and the injection pressure is increased if the vehicle speed increases, and the injection pressure is decreased if the vehicle speed decreases, specifically including:
determining the comprehensive speed based on the speed of the vehicle and the speed of the current position according to the wind direction of the current position and the running direction of the vehicle;
if the integrated speed increases, the injection pressure is increased, and if the integrated speed decreases, the injection pressure is decreased.
In some embodiments, the vehicle speed is obtained from a vehicle speed sensor, the vehicle driving direction is obtained from navigation information, the current position of the vehicle is uploaded to the internet after the current position of the vehicle is obtained through the navigation information, the real-time weather of the current position is obtained from the internet, and the wind speed of the current position and the wind direction of the current position are obtained from the real-time weather.
In one embodiment, the determining the integrated speed based on the vehicle speed and the current position wind speed according to the current position wind direction and the vehicle running direction specifically includes:
and if the current position wind direction is consistent with the vehicle running direction, carrying out weighted calculation on the vehicle speed and the current position wind speed to obtain the comprehensive speed, otherwise, adopting the vehicle speed as the comprehensive speed.
The wind direction refers to the direction in which the wind blows, and the vehicle traveling direction refers to the direction in which the vehicle is going. Therefore, if the current position wind direction coincides with the vehicle traveling direction, it means that natural wind in the outside environment is blown toward the windshield glass of the vehicle. At this time, calculate the integrated velocity V Heald ＝K1*V Vehicle with a frame +K2*V Wind power . Wherein V is Vehicle with a frame For the speed of the vehicle, V Wind power For the current position wind speed, K1 is the vehicle speed weight, and K2 is the current position wind speed weight. The specific vehicle speed weight and the current position wind speed weight can be obtained through high-speed running test calibration of specific vehicle types.
If the current position wind direction is opposite to the vehicle running direction, natural wind representing the environment outside the vehicle blows to the rear of the vehicle, and the natural wind does not blow to the front windshield glass, and the influence on the downward pressure of the washing liquid is only the influence on the external air flow caused by the high-speed running of the vehicle. Therefore, the vehicle speed is used as the integrated speed to control the injection pressure of the washing liquid.
According to the embodiment, after the pressure of the water pump is regulated according to the vehicle speed, the spraying position of the washing liquid can be always maintained at the designed target position, the service efficiency of the washing liquid is improved, and the influence of splashing of the washing liquid on vehicles and pedestrians at two sides and behind when the vehicle is stationary or runs at a low speed is reduced. Meanwhile, the input voltage of the water pump is adjusted based on the vehicle speed, so that the self-adaptive control of the injection pressure of the washing liquid is realized, the vehicle speed is easier to obtain than other parameters, and the cost is lower. In addition, the vehicle speed is partitioned, the input voltage of the water pump is adaptively controlled at a high speed, and the input voltage of the water pump is not adaptively controlled at a low speed, so that excessive intervention is avoided, and the waste of computational resources is avoided. And finally, adding the wind speed of external natural wind for correction, so that the adjustment is more accurate.
Fig. 6 is a flowchart showing a control method of a vehicle windshield cleaning system according to still another embodiment of the present application, including:
step S601, obtaining a relative speed of an air flow outside the vehicle, wherein the relative speed of the air flow outside the vehicle is the relative speed of the air flow blown to the window glass of the vehicle;
in step S602, if the outside air flow relative speed increases, the injection pressure is increased, and if the outside air flow relative speed decreases, the injection pressure is decreased.
Specifically, the present embodiment executes step S601 to obtain the relative speed of the air flow outside the vehicle when the user turns on the vehicle windshield cleaning system.
In some embodiments, the off-board air flow relative speed is obtained from an off-board air flow relative speed sensor provided on the vehicle.
The external air flow is directly responsible for the influence of the downward pressure on the washing liquid, so that the relative speed of the external air flow is directly obtained, and the jet pressure can be more accurately controlled to offset the influence of the air flow on the jet of the washing liquid.
Then, step S602 is performed to increase the injection pressure if the outside air flow relative speed increases, and to decrease the injection pressure if the outside air flow relative speed decreases.
In some embodiments, a vehicle windshield cleaning system employs a water pump to spray a cleaning solution.
In one embodiment, if the relative speed of the air flow outside the vehicle increases, the injection pressure is increased, and if the relative speed of the air flow outside the vehicle decreases, the injection pressure is decreased, including:
if the relative speed of the air flow outside the vehicle increases, the input voltage of a water pump for spraying the washing liquid of the windshield washer system is increased, and if the relative speed of the air flow outside the vehicle decreases, the input voltage is decreased.
Under the condition of not changing the power of the water pump, the input voltage of the water pump is adjusted by the control device, so that the control of the injection pressure of the washing liquid and the target position is realized: when the relative speed of the air flow outside the vehicle is low, the air flow has small influence on the injection of the washing liquid, and the input voltage of the water pump is reduced through the control device, so that the washing liquid falls at a reasonable target position; along with the increase of the relative speed of the air flow outside the vehicle, the influence of the air flow on the injection of the washing liquid is gradually increased, the input voltage of the water pump is increased through the control device, and the injection pressure of the nozzle is correspondingly increased, so that the influence of the air flow on the injection of the washing liquid is counteracted.
In one embodiment, if the relative speed of the air flow outside the vehicle increases, the input voltage of the water pump of the windshield cleaning system for spraying the cleaning solution is increased, and if the relative speed of the air flow outside the vehicle decreases, the input voltage is decreased, specifically including:
if the relative speed of the air flow outside the vehicle is greater than the relative speed threshold of the air flow outside the vehicle and less than the relative speed threshold of the air flow outside the vehicle, the input voltage of a water pump used for spraying washing liquid by the windshield cleaning system is proportional to the relative speed of the air flow outside the vehicle.
In one embodiment, the method further comprises:
if the relative speed of the air flow outside the vehicle is less than or equal to a first relative speed threshold of the air flow outside the vehicle, the input voltage is kept to be a first voltage value;
and if the relative speed of the air flow outside the vehicle is greater than or equal to a second relative speed threshold of the air flow outside the vehicle, maintaining the input voltage to be a second voltage value, wherein the second voltage value is greater than the first voltage value.
When the relative speed of the air flow outside the vehicle is smaller than or equal to the first relative speed threshold of the air flow outside the vehicle, the air flow outside the vehicle has no influence or has little influence on the injection of the washing liquid, and the injection pressure does not need to be increased at the moment, so that the input voltage is kept to be a first voltage value.
When the relative speed of the air flow outside the vehicle is larger than the relative speed threshold value of the air flow outside the first vehicle and smaller than the relative speed threshold value of the air flow outside the second vehicle, the influence of the air flow on the washing liquid injection is gradually increased, so that the input voltage is gradually increased. Wherein, the relative speed of the air flow outside the vehicle is in direct proportion to the input voltage.
In addition, in order to avoid the input voltage from being excessively large, when the relative speed of the air flow outside the vehicle is equal to or greater than the second relative speed threshold of the air flow outside the vehicle, the input voltage is kept at the second voltage value.
In some embodiments, the second voltage value is a maximum voltage value that the water pump is permitted to input, and the second off-vehicle airflow relative speed threshold is an off-vehicle airflow relative speed value at which the input voltage reaches the second voltage value.
The relation between the input voltage of the water pump and the relative speed of the air flow outside the vehicle, namely the proportional coefficient of the relative speed of the air flow outside the vehicle can be obtained through the calibration of a high-speed running test of a specific vehicle type.
In some embodiments, if the vehicle exterior airflow relative velocity is greater than the first vehicle exterior airflow relative velocity threshold and less than the second vehicle exterior airflow relative velocity threshold, a voltage vehicle exterior airflow relative velocity scaling factor is obtained, and the input voltage is calculated as a product of the voltage vehicle exterior airflow relative velocity scaling factor and the vehicle exterior airflow relative velocity as the input voltage.
According to the embodiment, after the pressure of the water pump is regulated according to the relative speed of the air flow outside the vehicle, the spraying position of the washing liquid can be always maintained at the designed target position, and the use efficiency of the washing liquid is improved. Meanwhile, the input voltage of the water pump is adjusted according to the relative speed of the air flow outside the vehicle, so that the self-adaptive adjustment of the jet pressure of the washing liquid is realized, and the relative speed of the air flow outside the vehicle is not required to be indirectly reflected through other parameters, so that the adjustment is more accurate. Finally, the relative speed of the air flow outside the vehicle is partitioned, when the relative speed of the air flow outside the vehicle is high, the input voltage of the water pump is adaptively controlled, and when the relative speed of the air flow outside the vehicle is low, the input voltage of the water pump is not adaptively controlled, so that excessive intervention is avoided, and the waste of calculation resources is avoided.
