[0027] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0028] The following describes a wiper control method, a computer-readable storage medium, a vehicle, and a wiper control device according to embodiments of the present invention with reference to the accompanying drawings.

[0029] Figure 1 FIG. 4 is a flow chart of a method for controlling a wiper according to an embodiment of the present invention.

[0030] like Figure 1 As shown, the control method of the wiper according to the embodiment of the present invention may include the following steps:

[0031] S1, obtaining outdoor ambient temperature and vehicle speed information.

[0032] S2, when the outdoor environment temperature is less than a preset temperature threshold and the vehicle speed information is less than a preset vehicle speed threshold, obtaining the surface state of the windshield. The preset temperature threshold and the preset vehicle speed threshold can be determined according to actual conditions.

[0033] S3, when it is determined according to the surface state of the windshield that there is a preset obstacle, the wiper is controlled to enter a protection mode, wherein the preset obstacle may be determined according to actual conditions.

[0034] Specifically, the smart wiper winter protection function is a control method for cold winter scenes when the smart wiper is in automatic mode. The main goal is to improve the user experience and avoid the trouble of the wiper freezing and erroneous start in winter. First, the outdoor ambient temperature and vehicle speed information can be obtained, that is, based on the outdoor ambient temperature and vehicle speed information, it can be determined whether the winter protection mode may be required. For example, the temperature of the outdoor environment and the current speed of the vehicle can be obtained in real time through the vehicle's sensor system (such as temperature sensors and speed sensors). If the temperature sensor is installed on the outside of the vehicle, it can accurately measure the outside air temperature, and the speed sensor determines the vehicle speed by measuring the rotation speed of the wheels.

[0035] When the outdoor ambient temperature and vehicle speed information are obtained, the outdoor ambient temperature and vehicle speed information can be judged to further confirm whether the wiper winter protection mode needs to be activated to prevent the wiper from being mistakenly started under low temperature and low speed conditions (which may indicate that the vehicle is stopped or driving slowly). For example, the preset temperature threshold is -10°C and the preset vehicle speed threshold is 7km / h. When it is detected that the outdoor ambient temperature is lower than the preset temperature threshold (-10°C) and the vehicle speed is lower than the preset vehicle speed threshold (7km / h), it means that the current outdoor ambient temperature is low and the vehicle is not started or is driving slowly. At this time, due to the low outdoor ambient temperature, there may be snow or frost on the vehicle windshield. In order to avoid the wiper from being mistakenly identified and started, the surface state of the windshield can be obtained. For example, it can be obtained through an infrared sensor, a camera or other types of sensors that can identify whether there is snow, ice or other obstacles on the windshield.

[0036] It should be noted that in cold weather, even if the outdoor temperature is below the preset temperature threshold, if the vehicle is traveling at high speed, the ice and snow on the windshield may have been cleared by wind or manpower. At this time, it may be appropriate to start the wipers, so it is necessary to ensure that the vehicle speed is less than the preset speed threshold.

[0037] Thus, when it is determined that there is a preset obstacle based on the surface state of the windshield, the wiper can be controlled to enter a protection mode. For example, the preset obstacle is pre-set as snow and ice. When it is determined that there is snow or ice on the surface of the windshield, the wiper is controlled to enter a protection mode to protect the wiper from damage and prevent the wiper from being used under inappropriate conditions. For example, in this protection mode, the wiper will not start until the obstacle is removed or the environmental conditions change. Thus, it is possible to avoid misidentification and erroneous start of the wiper, improve the user experience, and protect the wiper in the cold winter season, thereby increasing the service life of the wiper and reducing the frequency of wiper maintenance.

[0038] According to an embodiment of the present invention, controlling the wiper to enter a protection mode includes: controlling the wiper to enter a manual control wiping mode.

[0039] Specifically, when the wipers are controlled to enter the protection mode, the wipers can be controlled to enter the manual control wiping mode, ensuring that the wipers will not start automatically under certain environmental conditions, such as low temperature or icy and snowy weather, thereby avoiding possible damage or unnecessary use.

[0040] For example, in cold winter, especially when the temperature is below freezing, the rubber strip of the wiper may harden due to the low temperature, or freeze to the windshield due to snow or ice. Automatically starting the wiper may cause the following problems: damage to the wiper, frozen wipers may tear or be damaged when starting. Affecting driving safety, if the wiper cannot work properly due to freezing, the driver's vision may be blocked, increasing the risk of accidents. Therefore, in the manual control wiper mode, the driver can manually start the wiper according to actual needs. This allows the driver to operate the wiper only when he confirms that the ice and snow on the windshield have been cleared and the wiper can be used safely. This prevents the wiper from automatically starting the wiper when it detects rainfall or humidity changes. In addition, the vehicle's dashboard or central control display can also display information that the wiper is currently in manual mode, or a sound prompt can be issued to inform the driver that the wiper has been placed in manual mode.

[0041] According to an embodiment of the present invention, after controlling the wiper to enter the protection mode, the control method of the wiper further includes: controlling a heating device corresponding to the windshield to start operating.

[0042] Specifically, after it is determined that the wiper enters the protection mode, it indicates that there are obstacles such as snow or frost on the windshield of the current vehicle, and at this time, the heating device corresponding to the windshield can be controlled to start running. For example, the heating device can be a defroster, that is, by controlling the heating device to start running, the windshield can be heated to quickly melt the snow or ice, so that the obstacles on the windshield can be cleared, ensuring that the driver has a clear view and improving driving safety.

[0043] In addition, the heating device can be connected to a temperature sensor to monitor the temperature of the glass and adjust the heating intensity to prevent the windshield from overheating. The working status of the windshield heating device can be displayed on the vehicle's instrument panel or central control display.

[0044] According to an embodiment of the present invention, the method for controlling a windshield wiper further includes: controlling the windshield wiper to exit a protection mode when the vehicle speed information is greater than or equal to a preset vehicle speed threshold.

[0045] Specifically, vehicle speed information is a key factor in determining whether the vehicle is moving and whether the driving conditions are suitable for using wipers. For example, the preset speed threshold is 7km / h. When the vehicle speed information is greater than or equal to the preset speed threshold (7km / h), it means that the current vehicle speed is high and the vehicle is considered to be moving normally (only when the obstacles are cleared will the driver accelerate normally). At this time, the wiper may need to intervene, thereby controlling the wiper to exit the protection mode.

[0046] According to an embodiment of the present invention, after controlling the wiper to exit the protection mode, the wiper control method further includes: controlling the wiper to enter an automatic control wiping mode.

[0047] Further, according to an embodiment of the present invention, when the wiper operates in the automatic control wiping mode, the control method of the wiper further includes: controlling the wiping frequency of the wiper according to data detected by the rain sensor.

[0048] Specifically, after controlling the wipers to exit the protection mode, the wipers can also be controlled to enter the automatic control wiping mode. That is, in the automatic control wiping mode, the operating frequency of the wipers can be automatically adjusted according to the changes in rainfall or vehicle speed to ensure that the windshield is always clear, thereby reducing the driver's visual interference and improving driving safety in rainy or snowy days. In addition, the automatic control method reduces the need for the driver to manually adjust the wiper frequency, providing a more comfortable driving experience.

[0049] For example, the wiper frequency can be controlled by the data detected by the rain sensor. For example, in the case of heavy rainfall, the wiper frequency can be controlled to increase, and in the case of light rainfall, the wiper frequency can be controlled to decrease. The working frequency of the wiper can be automatically adjusted in real time, so that the wiper can be in a better working state and the driving safety of the driver can be improved. Among them, the rain sensor can be integrated on the front windshield or near the rearview mirror inside the car, which can sense the raindrops on the windshield and adjust the wiper speed according to the size and density of the raindrops. In this way, it can adapt to different driving conditions and automatically adjust the working state of the wiper, which not only protects the wiper from damage in bad weather, but also ensures a good field of view when needed, improving driving safety and comfort.

[0050] According to an embodiment of the present invention, the control method of the wiper further includes: when it is determined according to the surface state of the windshield that there is no preset obstacle, maintaining the control mode of the wiper unchanged.

[0051] Specifically, the surface state of the windshield is judged, and if it is determined that there is no preset obstacle based on the surface state of the windshield, the wiper control mode can be kept unchanged. That is to say, if the surface state of the windshield is good, there is no snow, ice or other obstacles, the protection mode will not be entered even when the temperature is low and the vehicle speed is low. That is, maintaining the current wiper control mode can ensure that the wipers continue to operate at an appropriate speed and manner to adapt to the current weather conditions. In addition, frequent switching of wiper modes may cause unnecessary wear or interfere with the driver, and keeping the wiper control mode unchanged can reduce these problems.

[0052] Combine the following Figure 2The control method of the present invention will be described.

[0053] As a specific example, the control method of the wiper of the present invention may include the following steps:

[0054] S101, obtaining outdoor ambient temperature and vehicle speed information.

[0055] S102, determine whether the outdoor environment temperature is less than a preset temperature threshold and whether the vehicle speed information is less than a preset vehicle speed threshold. If yes, execute step S103; if not, execute step S108.

[0056] S103, obtaining the surface state of the windshield.

[0057] S104, determining whether there is a preset obstacle according to the surface state of the windshield. If yes, proceed to step S105; if not, proceed to step S109.

[0058] S105, controlling the wiper to enter a manual control wiping mode, and controlling a heating device corresponding to the windshield to start operating.

[0059] S106, whether the vehicle speed information is greater than or equal to a preset vehicle speed threshold. If yes, execute step S107; if not, execute step S105.

[0060] S107, controlling the wiper to exit the protection mode.

[0061] S108, controlling the wiper to enter an automatic control wiping mode.

[0062] S109, keeping the control mode of the wiper unchanged.

[0063] In summary, according to the wiper control method of the embodiment of the present invention, the outdoor environment temperature and vehicle speed information are obtained, and when the outdoor environment temperature is less than the preset temperature threshold and the vehicle speed information is less than the preset vehicle speed threshold, the surface state of the windshield is obtained, and when it is determined that there is a preset obstacle according to the surface state of the windshield, the wiper is controlled to enter the protection mode. Therefore, the method can avoid the wiper from misidentifying and erroneously starting, improve the user experience, and protect the wiper in the cold winter season, increase the service life of the wiper, and reduce the frequency of wiper maintenance.

[0064] Corresponding to the above embodiment, the present invention also proposes a computer-readable storage medium.
