Preferred embodiments of the present invention are provided in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0044] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time.

[0045] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which the present invention belongs. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0046] The rearview mirror is an important component for observing the rear and side road conditions during driving. Its cleanliness directly affects the driver's field of vision and driving safety. However, in daily use, the surface of the rearview mirror is easily contaminated by dust, mud, raindrops, snowflakes, etc., especially when driving at high speeds or in bad weather conditions. The adhesion of dirt will cause obstruction of vision and affect driving judgment. Traditional rearview mirror cleaning methods mainly rely on manual wiping or simple protective measures, which are difficult to meet the cleaning needs of long-term driving or complex environments. Therefore, how to ensure that the rearview mirror maintains a clear field of vision in various environments is a key issue to improve driving safety and convenience.

[0047] Specifically in the application field of buses, since the installation position of the bus rearview mirror is relatively high, its lowest edge is usually about 1800mm from the ground, which makes it difficult to clean and maintain. Especially when driving on the highway, the vehicle speed is fast and it is difficult to stop temporarily, making it difficult to remove pollutants such as dust, rain, snow and so on on the surface of the rearview mirror in time, affecting the driver's field of vision and thus reducing driving safety.

[0048] In order to ensure that the rearview mirror maintains a clear view, the embodiment of the present application provides a cleaning device for the rearview mirror, such as Figure 1As shown, the device may include a controller 1, a detection member and a cleaning member arranged on the rearview mirror. The controller 1 obtains dirt information of the rearview mirror surface through the detection member, and when the dirt information meets a preset excessive dirt condition, the controller controls the cleaning member to clean the rearview mirror.

[0049] In one embodiment, Figure 2 As shown, a cleaning method for a rearview mirror is provided, wherein the method is applied to Figure 1 The controller 1 in the example is used as an example to illustrate, including the following steps:

[0050] Step 202, obtaining dirt information of the rearview mirror surface.

[0051] The dirt information includes the overall dirtiness of the mirror surface.

[0052] Step 204 , when the total dirtiness level meets a preset excessive dirtiness condition, control the cleaning component of the vehicle to clean the mirror surface of the rearview mirror.

[0053] Step 206, repeating the steps of obtaining the degree of dirtiness and performing the cleaning operation until the degree of dirtiness does not satisfy the preset over-dirtiness condition.

[0054] Exemplarily, the vehicle monitors the mirror surface condition in real time through sensors installed around the rearview mirror (such as optical cameras, infrared sensors, laser sensors or environmental monitoring sensors), obtains dirt information, comprehensively evaluates the coverage and concentration of pollutants such as dirt, dust, rain, snowflakes, etc. on the mirror surface, and determines whether the preset super-pollution condition is met by analyzing the total degree of dirt. The super-pollution condition can be set according to different scenarios, for example: visibility threshold: when the mirror surface transmittance or reflectivity is lower than the set threshold (such as 70%), cleaning is triggered; pollution accumulation time: when the pollution continues for a certain period of time without cleaning, the cleaning operation is automatically started; environmental condition linkage: lower the trigger threshold in rainy and snowy weather or dusty environment to increase the cleaning frequency. When the super-pollution condition is met, the system controls the cleaning component to clean the rearview mirror surface.

[0055] Among them, the cleaning methods may include one or more of the following: spray cleaning: spray cleaning fluid or high-pressure water mist onto the surface of the rearview mirror through a nozzle to remove attached dust, mud, rainwater and other pollutants; scraper wiping: use a micro scraper device to imitate the working principle of a wiper to scrape off water droplets and dirt on the mirror; ultrasonic vibration: integrate an ultrasonic generator on the mirror surface to remove dirt from the mirror through high-frequency vibration; nano-coating self-cleaning: combined with a hydrophobic and oleophobic coating, it makes it difficult for dirt to adhere, and cooperates with other cleaning methods to improve the cleaning effect; heating deicing: in a low temperature environment, a mirror heating device is used to melt snow and frost to prevent it from affecting the line of sight.

[0056] After completing a cleaning operation, the controller 1 re-acquires the dirtiness of the rearview mirror and determines whether the preset excessive dirtiness condition is still met. If there is still a lot of dirt on the mirror surface, the cleaning operation is continued until the dirtiness is reduced to an acceptable range. In order to improve the cleaning efficiency, the system can set a maximum number of cleaning times or adjust the cleaning method according to the cleaning effect.

[0057] The above-mentioned cleaning method of the rearview mirror obtains dirt information of the rearview mirror surface; the dirt information includes the total dirtiness of the mirror surface; when the total dirtiness meets the preset super-dirt condition, the cleaning part of the vehicle is controlled to clean the mirror surface of the rearview mirror; the steps of obtaining the dirtiness and performing the cleaning operation are repeated until the dirtiness does not meet the preset super-dirt condition. The embodiment of the present application obtains the dirtiness of the mirror surface, and when the total dirtiness meets the preset super-dirt condition, the cleaning part is controlled to clean the mirror surface, and the dirtiness is repeatedly obtained until the preset super-dirt condition is not met, thereby completing the cleaning. The embodiment of the present application is controlled by an electronic control system, which has sensing and recognition capabilities. When it is found that the dirtiness of the mirror surface exceeds the set standard, it will automatically clean and quickly wash away the dirt. It can continuously cycle and clean until the cleaning state of the rearview mirror reaches the set standard, thereby ensuring that the rearview mirror surface is always in a clean state.

[0058] In one embodiment, the rearview mirror is provided with a detection element, and the detection element includes a photoelectric sensor. The obtaining of dirt information of the rearview mirror surface includes: obtaining the total reflectivity of the mirror surface through the photoelectric sensor; and determining the total dirtiness of the mirror surface according to the total reflectivity of the mirror surface.

[0059] Among them, reference Figure 4 The photoelectric sensor can be a reflective photoelectric sensor 8 , which is disposed in the mirror cavity of the rearview mirror 2 and connected to the controller 1 .

[0060] Exemplarily, one or more photoelectric sensors are installed in a specific area of ​​the rearview mirror (such as the center or edge of the mirror or the mirror cavity); the photoelectric sensor emits a light beam of a specific wavelength (such as visible light, infrared light or laser) and measures the intensity of the reflected light; the photoelectric sensor sends the measured light intensity signal to the controller, and the controller obtains the total reflectivity of the mirror by calculating the intensity of the reflected light, thereby determining the total dirtiness of the mirror. When the total dirtiness of the mirror is greater than or equal to a preset dirtiness threshold, it is determined that the total dirtiness meets the preset over-dirtiness condition; when the total dirtiness of the mirror is less than the preset dirtiness threshold, it is determined that the total dirtiness does not meet the preset over-dirtiness condition.

[0061] In this embodiment, a detection element is provided on the rearview mirror to monitor the cleanliness of the mirror surface in real time and judge the degree of dirtiness according to the degree of reflection of the mirror surface. The detection element includes a photoelectric sensor, which uses photoelectric detection technology to accurately analyze the contamination of the mirror surface, thereby realizing automatic cleaning control.

[0062] In one embodiment, the cleaning member includes a flushing module, which includes a mirror flushing port and a fluid supply pipeline connected to the mirror flushing port; the cleaning member controlling the vehicle performs a cleaning operation on the mirror surface of the rearview mirror, including: conveying cleaning fluid to the mirror flushing port through the fluid supply pipeline; spraying cleaning fluid onto the mirror surface through the mirror flushing port so that the cleaning fluid flushes the mirror surface.

[0063] The flushing module may further include a suction device, which is disposed in the mirror cavity of the rearview mirror, one end of the suction device is connected to the vehicle's washer through the fluid supply pipeline, and the other end of the suction device is connected to the mirror flushing port through the fluid supply pipeline. When the controller controls the cleaning member of the vehicle to clean the mirror surface of the rearview mirror, the controller first starts the suction device, uses the suction device to extract cleaning fluid from the vehicle's washer, and then sprays it from the mirror flushing port through the fluid supply pipeline to flush the mirror surface.

[0064] In one embodiment, the cleaning member further comprises a drying module, and the drying module comprises a blowing unit and / or a heating unit; after spraying the cleaning liquid onto the mirror through the mirror flushing port, the method further comprises: drying the mirror through the drying module.

[0065] In one embodiment, the dirt information also includes dirt distribution information of the mirror surface; the cleaning device controlling the vehicle to clean the mirror surface of the rearview mirror also includes: adjusting the spray angle of the mirror flushing port according to the dirt distribution information of the mirror surface.

[0066] Exemplarily, the reflection intensity data of each area of ​​the mirror is collected by an array photoelectric sensor group; the controller divides the mirror into multiple detection grids, and calculates the local dirt coefficient of each grid according to the reflection intensity data of each area of ​​the mirror; the dirt distribution heat map is generated based on the gradient change of the dirt coefficient of adjacent grids. A dirt coordinate mapping model is established according to the dirt distribution heat map, and the dirt distribution information is converted into a three-dimensional flushing coordinate. An electric universal joint is set on the mirror flushing port, and the controller drives the electric universal joint to perform at least one of the following adjustments: horizontal deflection angle θ (0°≤θ≤180°), vertical pitch angle φ (-30°≤φ≤30°), and injection focus distance L (50mm≤L≤150mm).

[0067] In one embodiment, the method further includes: receiving a cleaning start instruction in response to a cleaning start operation for the rearview mirror; and controlling a cleaning member of the vehicle to perform a cleaning operation on the mirror surface of the rearview mirror according to the cleaning start instruction.

[0068] Exemplarily, a first control switch is provided on the vehicle dashboard, the first control switch is connected to the controller, and the first control switch is used to instruct a manual cleaning operation for the rearview mirror. When the first control switch receives a start operation, the first control switch sends a single or multiple start cleaning instruction to the controller, the controller receives the start cleaning instruction, and controls the cleaning element of the vehicle to perform a single or multiple cleaning operation on the rearview mirror according to the start cleaning instruction. For example, in a snowstorm or harsh environment, the driver can press the first control switch, and the controller sprays washing liquid to clean the mirror surface, and then automatically dries the lens by electric heating.

[0069] In other embodiments, a second control switch is provided on the vehicle instrument panel, the second control switch is connected to the controller, and the second control switch is used to instruct the automatic cleaning operation for the rearview mirror. When the second control switch receives the start operation, the second control switch sends a start cleaning instruction for automatic cleaning to the controller, the controller receives the start cleaning instruction, and according to the start cleaning instruction, performs the above steps of repeatedly obtaining the dirtiness and performing the cleaning operation until the dirtiness does not meet the preset excessive dirtiness condition.

[0070] In this embodiment, the first control switch and the second control switch can be used to switch between manual cleaning and automatic cleaning.

[0071] In one embodiment, please refer to Figure 3 and Figure 4 , the controller 1 is the brain of the whole set of equipment, which is used to determine whether the automatic cleaning mode needs to be turned on. The control switch is located on the instrument panel for manual cleaning. A reflective photoelectric sensor 8 is arranged on the mirror surface of the rearview mirror 2, which detects the degree of dirtiness of the mirror surface through the refraction of light. When it reaches a predetermined value, the automatic cycle cleaning mode is turned on. The water pump 3 is arranged in the housing of the rearview mirror 2, with a water inlet hole and a water outlet hole, which are used to extract washing liquid to clean the mirror surface of the rearview mirror. The water inlet pipe 4 is connected to the washer 6 at one end and the water inlet hole of the water pump 3 at the other end. The shower pipe 5 is connected to the water outlet hole of the water pump 3. The shower pipe 5 is arranged on the upper edge of the rearview mirror 2 lens, and is made of acrylic material. This material has good toughness and is not easy to wear; the surface hardness is high and it is not easy to scratch; it has good light transmittance, does not affect the field of vision, and is retractable, which can effectively prevent raindrops from falling on the mirror surface on rainy days. There is a pipeline at 10 degrees to the vertical direction on it, which can evenly atomize and spray washing liquid over a large area to clean the mirror surface. The battery 7 and the scrubber 6 are shared by the entire vehicle and are located inside the cabin.

[0072] When the reflective photoelectric sensor 8 detects that the mirror surface is uneven and has a lot of dirt and dust, reaching a preset value, the system enters the automatic circulation cleaning mode. The controller 1 starts the water pump 3, and the washing liquid drawn from the washer 6 flows down from the mirror surface through the shower pipe 5 to wash away the dirt on the mirror surface. The controller 1 starts the electric heating of the rearview mirror lens to dry the lens. The reflective photoelectric sensor 8 detects the reflectivity of the mirror surface. If it does not reach the preset value, repeat 1. When the reflective photoelectric sensor 8 detects that the mirror surface is flat and clean, the automatic circulation mode stops working. If it is a blizzard or a harsh environment, the driver can press the control switch to spray the washing liquid to clean the mirror surface, and the electric heating will automatically dry the lens after the cleaning is completed.

[0073] With the above-mentioned cleaning method for the rearview mirror, the system can automatically cycle to keep the rearview mirror clean all the time.
