[0047] In order to enable those skilled in the art to better understand the solution of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0048] Refer to Figures 1 to 6 , the present application provides a rain shielding method for frameless exterior rearview mirrors and its rain shielding system, which can solve the problem in the prior art that due to the use of a frameless structure, there is no shielding around the lens, and rainwater is easily directly dropped on the lens, thereby causing the inability to observe the rear view through the exterior rearview mirror.

[0049] In the first aspect, the embodiments of the present application provide a rain shielding method for frameless exterior rearview mirrors, and the rain shielding method for frameless exterior rearview mirrors includes:

[0050] 101: Obtain the current rainfall amount, and based on the current rainfall amount and the corresponding relationship between the rainfall amount and the deployment gear of the rain shield 2, obtain the target deployment gear of the rain shield 2;

[0051] 102: Obtain the current vehicle speed, and based on the current rainfall amount and the current vehicle speed, determine whether the vehicle meets the deceleration condition;

[0052] 103: If the deceleration condition is met, control the vehicle to decelerate, and control the rain shield 2 to deploy according to the target deployment gear;

[0053] 104: If the deceleration condition is not met, control the rain shield 2 to deploy according to the target deployment gear.

[0054] In this application, by obtaining the current rainfall amount and based on the current rainfall amount and the corresponding relationship between the rainfall amount and the unfolding gear of the rain shield 2, the target unfolding gear of the rain shield 2 is obtained; by obtaining the current vehicle speed and based on the current rainfall amount and the current vehicle speed, it is determined whether the vehicle meets the speed reduction condition. If the speed reduction condition is met, the vehicle is controlled to decelerate, and the rain shield 2 is controlled to unfold according to the target unfolding gear. If the speed reduction condition is not met, the rain shield 2 is controlled to unfold according to the target unfolding gear. So that the system determines the rain shielding method based on the current rainfall amount and the current vehicle speed, and shields the rain by unfolding the rain shield 2, reducing the rainwater falling on the mirror surface of the external rearview mirror 1 and avoiding the problem of being unable to observe the rear view through the external rearview mirror.

[0055] It should be noted that for steps 101 and 102, step 101 can be executed first and then step 102; they can also be executed in parallel, that is, steps 101 and 102 are executed simultaneously; or step 102 can be executed first and then step 101. In this application, the execution order of steps 101 and 102 is not limited.

[0056] Based on the above embodiments, in this embodiment, after controlling the rain shield 2 to unfold according to the target unfolding gear, the method further includes:

[0057] Heating the mirror surface of the external rearview mirror 1.

[0058] In this embodiment, a heating function is set on the external rearview mirror 1. Specifically: a heating device is installed on the external rearview mirror. After the rain shield 2 unfolds according to the target unfolding gear, the heating device is started, so that the rain shield 2 and the heating device cooperate to jointly reduce the rainwater on the mirror surface of the external rearview mirror 1. Among them, the rain shield 2 can directly block part of the rainwater that will fall on the mirror surface of the external rearview mirror 1, and another part of the rainwater that falls on the mirror surface of the external rearview mirror 1 is evaporated after being heated by the heating device, reducing the rainwater that has fallen on the mirror surface of the external rearview mirror 1.

[0059] Based on the above embodiments, in this embodiment, obtaining the current rainfall amount specifically includes steps 1011 to 1013:

[0060] Step 1011: Obtain the area of the rainwater covering the mirror surface of the current external rearview mirror 1 and calculate the ratio of this rainwater area to the mirror surface area of the external rearview mirror 1;

[0061] Step 1012: Compare the ratio with each threshold interval to determine the threshold interval where the ratio is located;

[0062] Step 1013: Use the rainfall amount corresponding to the threshold interval where the ratio is located as the current rainfall amount.

[0063] Specifically, in this embodiment, a sensor is provided on the exterior rearview mirror 1. For example, an infrared sensor can be provided on the exterior rearview mirror 1 to identify the rainwater area on the mirror surface of the exterior rearview mirror 1, and the current rainfall is indirectly determined through the rainwater area on the mirror surface of the exterior rearview mirror 1.

[0064] In addition, a rain drop sensor can also be provided on the vehicle to directly measure the current rainfall. However, since the frameless exterior rearview mirror 1 is shielded from rain in this application, identifying the rainwater area on the mirror surface of the exterior rearview mirror 1 can more accurately determine whether the exterior rearview mirror 1 needs to be shielded from rain. Therefore, identifying the rainwater area on the mirror surface of the exterior rearview mirror 1 and indirectly determining the current rainfall through the rainwater area on the mirror surface of the exterior rearview mirror 1 is the preferred method in this application.

[0065] Among them, in this embodiment, the threshold range includes a first threshold range, a second threshold range, and a third threshold range; the first threshold range corresponds to a first rainfall amount, the second threshold range corresponds to a second rainfall amount, and the third threshold range corresponds to a third rainfall amount; at the same time, it is set that the first rainfall amount is greater than the second rainfall amount, and the second rainfall amount is greater than the third rainfall amount.

[0066] It should be noted that in other embodiments, the threshold range is not limited to the first threshold range, the second threshold range, and the third threshold range, and fourth threshold range, fifth threshold range... can also be added according to actual situations, and the fourth rainfall amount, fifth rainfall amount... are correspondingly set.

[0067] In this embodiment, the first threshold range, the second threshold range, and the third threshold range can be set according to actual situations:

[0068] For example: when the ratio of the rainwater area covered on the mirror surface of the exterior rearview mirror 1 detected by the infrared sensor to the mirror surface area of the exterior rearview mirror 1 exceeds 2 / 3, it is determined that the current is the first rainfall amount; when the ratio of the rainwater area covered on the mirror surface of the exterior rearview mirror 1 detected by the infrared sensor is greater than 1 / 3 and less than or equal to 2 / 3, it is determined that the current is the second rainfall amount; when the ratio of the rainwater area covered on the mirror surface of the exterior rearview mirror 1 detected by the infrared sensor is less than 1 / 3, it is determined that the current is the third rainfall amount.

[0069] Taking the rainfall including the first rainfall amount, the second rainfall amount, and the third rainfall amount as an example for illustration, on the basis of the above embodiment, in this embodiment, the corresponding relationship between the rainfall amount and the unfolding position of the rain shield 2 includes:

[0070] When the rainfall is the first rainfall amount, the unfolding gear of the rain shield 2 is the first gear; when the rainfall is the second rainfall amount, the unfolding gear of the rain shield 2 is the second gear; when the rainfall is the third rainfall amount, the rain shield 2 does not unfold. Among them, the unfolding area when the rain shield 2 unfolds to the first gear is larger than the unfolding area when the rain shield 2 unfolds to the second gear.

[0071] In this embodiment, there are various setting methods for the rain shield 2:

[0072] In some possible implementations, the rain shield 2 includes a top plate 20, side plates 21 and a bottom plate 22. The top plate 20, side plates 21 and bottom plate 22 are all movably connected to the external rearview mirror 1. The top plate 20 is located above the external rearview mirror 1, the side plates 21 are located on the side of the external rearview mirror 1, and the bottom plate 22 is located below the external rearview mirror 1.

[0073] In this embodiment, refer to Figures 1 to 3 As shown, when the unfolding gear of the rain shield 2 is the first gear, it drives the top plate 20, side plates 21 and bottom plate 22 to all unfold; when the unfolding gear of the rain shield 2 is the second gear, it drives the top plate 20 to unfold; when the rainfall is the third rainfall amount, the top plate 20, side plates 21 and bottom plate 22 do not unfold.

[0074] In some other possible embodiments, the rain shield 2 includes a top plate 20. The top plate 20 is movably connected to the external rearview mirror 1 and is located above the external rearview mirror 1.

[0075] In this embodiment, when the unfolding gear of the rain shield 2 is the first gear, it drives the top plate 20 to unfold to the first position; when the unfolding gear of the rain shield 2 is the second gear, it drives the top plate 20 to unfold to the second position; the extension length of the top plate 20 at the first position is greater than the extension length of the top plate 20 at the second position.

[0076] The above embodiments are only various possible implementation manners of the embodiments of the present application, and the embodiments of the present application are not limited thereto.

[0077] On the basis of the above embodiments, in this embodiment, based on the current rainfall and the current vehicle speed, it is judged whether the vehicle meets the speed reduction condition, which specifically includes steps 1021 to step 1024:

[0078] Step 1021: Compare the current rainfall with each rainfall interval to obtain the rainfall interval where the current rainfall is located;

[0079] Step 1022: Compare the current vehicle speed with each vehicle speed interval to obtain the vehicle speed interval where the current vehicle speed is located;

[0080] Step 1023: Determine whether the combination formed by the rainfall range where the current rainfall is located and the vehicle speed range where the current vehicle speed is located is one of the deceleration combinations in the deceleration combination set formed based on the rainfall range and the vehicle speed range;

[0081] Step 1024: If so, the deceleration condition is met; otherwise, it is not met.

[0082] In this embodiment, determining whether the vehicle meets the deceleration condition is to prevent the vehicle from opening the rain shield 2 when driving at a high speed. When the rain shield 2 is deployed, it may be unstable due to the excessive vehicle speed and may cause the rain shield 2 to fly off.

[0083] The set rainfall ranges include the first rainfall range, the second rainfall range, and the third rainfall range. The vehicle speed ranges include the first speed threshold range, the second speed threshold range, and the third speed threshold range. Among them, the first speed threshold range refers to the low-speed threshold range, the second speed threshold range refers to the medium-speed threshold range, and the third speed threshold range refers to the high-speed threshold range.

[0084] To prevent the rain shield 2 from being unstable when deployed due to excessive vehicle speed and potentially causing the rain shield 2 to fly off, the deceleration combination set is set to include the deceleration combination formed by the third speed threshold range and the first rainfall range, and the deceleration combination formed by the third speed threshold range and the second rainfall range.

[0085] Specifically:

[0086] When the ratio of the rain-covered area on the mirror surface of the outside rearview mirror 1 detected by the infrared sensor to the mirror surface area of the outside rearview mirror 1 exceeds 2 / 3, it is determined that the current rainfall is the first rainfall, that is, the heavy rain state:

[0087] If the vehicle speed is in the third speed threshold range at this time, considering that when the rain shield 2 is opened at this time, it may be unstable when deployed due to the excessive vehicle speed, and the rain shield 2 may fly off. Therefore, after the vehicle decelerates, the rain shield 2 is automatically opened to the first gear, and at the same time, the heating function of the outside rearview mirror 1 is turned on; if the vehicle speed is in the second speed threshold range at this time, the rain shield 2 is automatically opened to the first gear, and at the same time, the heating function of the outside rearview mirror 1 is turned on; if the vehicle speed is in the first speed threshold range at this time, the rain shield 2 is automatically opened to the first gear, and at the same time, the heating function of the outside rearview mirror 1 is turned on.

[0088] When the ratio of the rain-covered area on the mirror surface of the outside rearview mirror 1 detected by the infrared sensor to the mirror surface area of the outside rearview mirror 1 is greater than 1 / 3 and less than or equal to 2 / 3, it is determined that the current rainfall is the second rainfall, that is, the moderate rain state:

[0089] If the vehicle speed is in the third speed threshold range at this time, considering that when the rain shield 2 is opened at this time, it may be unstable when it is deployed due to the excessive vehicle speed, and the rain shield 2 may be ejected. Therefore, after the vehicle speed is reduced, the rain shield 2 is automatically opened to the second gear, and the heating function of the outside rearview mirror 1 is turned on at the same time; if the vehicle speed is in the second speed threshold range at this time, the rain shield 2 is automatically opened to the second gear, and the heating function of the outside rearview mirror 1 is turned on at the same time. According to the actual field of view occlusion, the driver can manually open the rain shield 2 to the first gear; if the vehicle speed is in the first speed threshold range at this time, the rain shield 2 is automatically opened to the second gear, and the heating function of the outside rearview mirror 1 is turned on at the same time. According to the actual field of view occlusion, the driver can manually open the rain shield 2 to the first gear.

[0090] When the infrared sensor detects that the ratio of the rain area covering the outside rearview mirror 1 to the mirror area of the outside rearview mirror 1 is less than 1 / 3, it is determined that the current is the third rainfall amount, that is, the light rain state:

[0091] If the vehicle speed is in the third speed threshold range at this time and does not affect the driver's field of view, the rain shield 2 is not automatically opened, and the driver cannot operate the rain shield 2 to open. Only the heating function of the outside rearview mirror 1 is turned on. The rain shield 2 can be manually opened only after the vehicle speed is reduced; if the vehicle speed is in the second speed threshold range at this time and does not affect the driver's field of view, the rain shield 2 is not automatically opened, and only the heating function of the outside rearview mirror 1 is turned on. The driver can operate to open the rain shield 2 by himself; if the vehicle speed is in the first speed threshold range at this time and does not affect the driver's field of view, the rain shield 2 is not automatically opened, and only the heating function of the outside rearview mirror 1 is turned on. The driver can operate to open the rain shield 2 by himself.

[0092] In this application:

[0093] When the rain shield 2 is opened: when the sensor set on the outside rearview mirror 1 encounters rain, it will send a rain signal to the central controller. After receiving the signal, the central controller judges according to the above control logic and sends an electric signal to the drive motor of the rain shield 2. After the drive motor of the rain shield 2 is powered on, the rain shield 2 is opened. At the same time, after it is deployed in place, it feeds back the status signal at this time to the body domain controller; when manually controlling to open the rain shield 2, the central controller directly sends an opening signal to the body domain controller. After receiving the signal, the central controller sends an electric signal to the drive motor of the rain shield 2. After the drive motor of the rain shield 2 is powered on, the rain shield 2 is opened. At the same time, after it is deployed in place, it feeds back the status signal at this time to the body domain controller.

[0094] When the rain shield cover 2 is closed: The central controller directly sends a closing signal to the vehicle body domain controller. After receiving the signal, the central controller sends an electric signal to the drive motor of the rain shield cover 2. After the drive motor of the rain shield cover 2 is powered on, the rain shield cover 2 is closed. At the same time, after it is closed in place, the status signal at this time is fed back to the vehicle body domain controller.

[0095] In a second aspect, an embodiment of the present application provides a frameless exterior rearview mirror rain shield system. The frameless exterior rearview mirror rain shield system includes: a first module and a second module. The first module is used to obtain the current rainfall amount, and based on the current rainfall amount and the correspondence between the rainfall amount and the deployment gear of the rain shield cover 2, obtain the target deployment gear of the rain shield cover 2; the second module is used to obtain the current vehicle speed, and based on the current rainfall amount and the current vehicle speed, determine whether the vehicle meets the deceleration condition. If the deceleration condition is met, control the vehicle to decelerate, and control the rain shield cover 2 to deploy according to the target deployment gear; if the deceleration condition is not met, control the rain shield cover 2 to deploy according to the target deployment gear.

[0096] In the present application, by obtaining the current rainfall amount, and based on the current rainfall amount and the correspondence between the rainfall amount and the deployment gear of the rain shield cover 2, the target deployment gear of the rain shield cover 2 is obtained; by obtaining the current vehicle speed, and based on the current rainfall amount and the current vehicle speed, determine whether the vehicle meets the deceleration condition. If the deceleration condition is met, control the vehicle to decelerate, and control the rain shield cover 2 to deploy according to the target deployment gear. If the deceleration condition is not met, control the rain shield cover 2 to deploy according to the target deployment gear. So that the system determines the rain shielding method through the current rainfall amount and the current vehicle speed, and shields the rain by deploying the rain shield cover 2, reducing the rain falling on the mirror surface of the exterior rearview mirror 1, and avoiding the problem of being unable to observe the rear view through the exterior rearview mirror.
