Description

Technical Field

[0001] The present application relates to the field of vehicle technology, and in particular to a method, device and vehicle for heating a streaming media rearview mirror. Background Art

[0002] With the development of technology, vehicle technology is becoming more and more advanced. At present, more and more vehicles are equipped with streaming media rearview mirrors, which indirectly present the rear view of the vehicle through the imaging of cameras and display screens. Streaming media rearview mirrors are divided into single-mode and dual-mode. Single-mode streaming media rearview mirrors are pure display screens, which can only observe camera imaging. Dual-mode streaming media rearview mirrors are covered with a layer of lens on the display screen. The light of the display screen can pass through the lens. After turning off the display screen, the lens can be used as a reflector, that is, it can observe the camera imaging and can also be used as a reflector to observe the reflected image.

[0003] However, the display screen of the streaming media rearview mirror is generally a liquid crystal display screen, and the activity of liquid crystal will decrease in a low temperature environment. Therefore, the imaging on the display screen will have a delayed image ghosting problem, thereby reducing the user experience. Summary of the invention

[0004] The present application provides a method, device, vehicle and storage medium for heating a streaming media rearview mirror, which can heat up the streaming media rearview mirror by increasing the power of the backlight to allow the backlight to dissipate heat when the streaming media rearview mirror is in a preset temperature environment, thereby eliminating the smear that occurs in the streaming media rearview mirror at low temperatures, thereby improving the user experience. The technical solution is as follows:

[0005] In a first aspect, a method for heating a streaming media rearview mirror is provided, the method comprising:

[0007] The power of the backlight is increased and the display screen module is controlled to display a preset picture, so that the heat emitted by the backlight can heat up the streaming media rearview mirror, and the light emitted by the backlight can be shielded by the preset picture.

[0008] In the present application, the streaming media rearview mirror includes a display screen module, and the display screen module includes a backlight. When it is detected that the streaming media rearview mirror is in a preset temperature environment, the streaming media rearview mirror can be controlled to start the reflector mode first. The reflector mode is a mode that reflects the environment behind the vehicle through the optical reflection principle, that is, when the streaming media rearview mirror has a low temperature drag problem, the user can observe the reflected environment behind the vehicle in the reflector mode. Then the power of the backlight is increased and the display screen module is controlled to display a preset picture. Since the brightness of the backlight will be higher after the power of the backlight is increased, the light of the backlight will affect the normal use of the reflector mode through the display screen module. Therefore, the display screen module can be controlled to display a preset picture while the power of the backlight is increased, such as displaying a pure black picture. Thereby, the heat emitted by the backlight can be used to heat up the streaming media rearview mirror, and the light emitted by the backlight can be blocked by the preset picture, so that the streaming media rearview mirror can be heated up by the heat emitted by the backlight without affecting the normal use of the rearview mirror by the user.

[0067] In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation methods of the present application will be further described in detail below with reference to the accompanying drawings.

[0068] It should be understood that the "multiple" mentioned in this application refers to two or more. In the description of this application, unless otherwise specified, " / " means or, for example, A / B can mean A or B; "and / or" in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships, for example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. In addition, in order to facilitate the clear description of the technical solution of this application, the words "first" and "second" are used to distinguish between the same items or similar items with basically the same functions and effects. Those skilled in the art can understand that the words "first" and "second" do not limit the quantity and execution order, and the words "first" and "second" do not limit them to be different.

[0069] Before describing the method for heating a streaming media rearview mirror provided in an embodiment of the present application, the structure of the streaming media rearview mirror involved in the embodiment of the present application is first described in detail.

[0070] For example, Figure 1 is a structural diagram of a streaming media rearview mirror provided in an embodiment of the present application. Figure 1 The streaming media rearview mirror includes a display screen module 101, a dimming glass 102 and a cover glass 103.

[0071] Among them, when the streaming media rearview mirror is Figure 1 When placed horizontally as shown, the dimming glass 102 covers the top of the display screen module 101 and is used to adjust the transmittance of the display screen module 101. It should be noted that the dimming glass 102 is a glass whose transparency can be changed by electrical control (voltage). Specifically, the transmittance of the dimming glass 102 is usually directly related to the voltage applied thereto, that is, when there is no voltage, the dimming glass 102 is in an opaque state, and the transmittance is very low and close to zero. As the voltage continues to increase, the transmittance of the dimming glass 102 will increase accordingly.

[0072] The cover glass 103 covers the dimming glass 102 to protect the dimming glass 102 and the display screen module 101 from being damaged.

[0073] Generally, the dimming glass that can adjust the transmittance and reflectance may include electrochromic glass, suspended particle device, liquid crystal dimming glass, and thermochromic dimming glass. In the embodiment of the present application, the dimming glass may be liquid crystal dimming glass. It can change the transmittance and reflectance by changing the arrangement of liquid crystal molecules through voltage.

[0074] As an example, the dimming glass 102 may adopt an LC lens (Liquid Crystal Lens) with adjustable reflectivity, wherein the LC lens includes a polarizer, a liquid crystal glass and an RPM film (Reflective Polarization Modulation).

[0075] For example, Figure 2 Schematic diagram of the working principle of a streaming media rearview mirror provided by an embodiment of the present application. Figure 2 The streaming media rearview mirror includes a display screen module 201 and an LC lens 202. The LC lens 202 includes a polarizer 203, a liquid crystal glass 204 and an RPM film 205.

[0076] In the embodiment of the present application, the streaming media rearview mirror includes a streaming media display mode and a reflector mode. The streaming media display mode is a mode for displaying the image behind the vehicle through the display screen module 201. The reflector mode is a mode for reflecting the environment behind the vehicle through the optical reflection principle.

[0077] It is worth noting that the user can manually switch between the above two modes through the physical button configured on the streaming media rearview mirror, or through the virtual button configured on the central control screen of the vehicle, which is not limited in the embodiment of the present application. In addition, the vehicle can also automatically switch between the above two modes according to the vehicle status (for example, reversing, high-speed driving, etc.).

[0078] like Figure 2 As shown in (a), when the display screen module 201 is powered on, the liquid crystal in the liquid crystal glass 204 is powered on and flipped, so that the transmittance of the LC lens 202 is maximized and the reflectivity is minimized. After the incident light passes through the polarizer 203, the reflectivity is 50%, and after continuing to pass through the RPM film 205, the reflectivity is 10%.

[0079] In this case, the streaming media rearview mirror is in a streaming media display mode, that is, a mode in which the image behind the vehicle is displayed through the display screen module 201. The LC lens 202 has the lowest reflectivity and the highest transmittance, so that the image displayed by the display screen module 201 can pass through the LC lens 202 to be seen by the user.

[0080] like Figure 2As shown in (b), when the display screen module 201 is not powered, that is, when the display screen module 201 is turned off, the arrangement state of the liquid crystal in the sandwiched liquid crystal glass 204 does not change, so that the transmittance of the LC lens 202 is small and the reflectance is large. In this case, the streaming media rearview mirror is in a reflector mode, that is, a mode that reflects the environment behind the vehicle through the principle of optical reflection. By increasing the reflectivity of the LC lens 202 and reducing the transmittance, the light from the environment behind the vehicle can be reflected after entering the LC lens 202, and further reflected into the user's eyes, so that the user can see the environment behind the vehicle.

[0081] The following is an explanation of the display screen module in the streaming media rearview mirror.

[0082] For example, Figure 3 is a structural diagram of a display screen module provided in an embodiment of the present application. Figure 3 The display screen module may include a backlight 301 and a liquid crystal layer 302 (ie, a liquid crystal display screen).

[0083] Among them, the backlight 301 is used to provide background light for the display screen module. By adjusting the brightness of the backlight 301, the user can clearly see the picture displayed by the display screen module under different lighting conditions. Optionally, the backlight 301 can be located at the top of the display screen module to provide light to the display area below. Of course, the backlight 301 can also be located at the bottom, left side or right side of the display screen module, which is not limited in the embodiment of the present application.

[0084] As an example, the backlight 301 can be any one of a light emitting diode (Light Emitting Diode, LED), an organic light emitting diode (Organic Light-Emitting Diode, OLED), or a micro light emitting diode (Micro Light Emitting Diode, Micro LED), etc. Of course, the backlight can also be other types of lamps, and the embodiments of the present application are not limited to this.

[0085] The liquid crystal layer 302 is used to display images, and can realize the function of a streaming media rearview mirror by displaying images captured by a camera behind the vehicle.

[0086] It should be noted that the core of the liquid crystal layer is the "change in the arrangement direction of the liquid crystal molecules", that is, the activity of the liquid crystal molecules. However, the liquid crystal material is very sensitive to the temperature of the environment. The lower the temperature, the slower the liquid crystal molecules flip, which means that the response time of the liquid crystal display will be longer, that is, there will be a smear phenomenon, affecting the display effect.

[0087] To this end, an embodiment of the present application provides a method for heating a streaming media rearview mirror, which can be applied to a scenario where the streaming media rearview mirror is in a preset temperature environment.

[0088] Specifically, the temperature of the streaming media rearview mirror is detected. When it is detected that the streaming media rearview mirror is in a preset temperature environment, the streaming media rearview mirror is first controlled to start the reflector mode, that is, the streaming media rearview mirror is first used normally by reflecting the image behind the vehicle through the optical reflection principle. Then the power of the backlight is increased to heat up the streaming media rearview mirror through the heat emitted by the backlight. After increasing the power of the backlight, the reflector mode will not work well, so the display screen module is also controlled to display a preset picture to block the light emitted by the backlight through the preset picture.

[0089] In this way, the heat emitted by the backlight heats up the streaming media rearview mirror, and the light emitted by the backlight is shielded by a preset image, so that the streaming media rearview mirror heats up through the backlight without affecting the user's normal use of the rearview mirror. In this way, the problem of ghosting of the streaming media rearview mirror in special temperature environments can be solved, and the user experience is improved.

[0090] The streaming media rearview mirror heating method provided in the embodiment of the present application is explained in detail below.

[0091] Figure 4 : is a flow chart of a method for heating a streaming media rearview mirror provided in an embodiment of the present application. The method can be applied to a vehicle equipped with a streaming media rearview mirror, and can be applied to a streaming media rearview mirror controller (Rearview Mirror Controller, RMC) of the vehicle. Figure 4 The method includes the following steps 401 and 402.

[0092] Step 401: When the streaming media rearview mirror is in a preset temperature environment, control the streaming media rearview mirror to start the reflector mode, the streaming media rearview mirror includes a display screen module, the display screen module includes a backlight, and the reflector mode is a mode that reflects the environment behind the vehicle through the optical reflection principle.

[0093] Streaming media rearview mirror can be used for the above Figure 1 The streaming media rearview mirror shown in the embodiment. The display screen module can be the above Figure 3 The display screen module shown in the embodiment includes a backlight.

[0094] The preset temperature environment can be pre-defined by a technician. For example, the technician can pre-define a temperature range. When the streaming media rearview mirror is within this temperature range, it is also within the preset temperature environment. In the embodiment of the present application, the preset temperature environment can be a low temperature environment. For example, the temperature range set by the technician can be the temperature range where the streaming media rearview mirror is deactivated at low temperature. Then, when the streaming media rearview mirror is within this temperature range, it can be considered that the streaming media rearview mirror is in a low temperature environment.

[0095] In this case, when the streaming media rearview mirror is in a preset temperature environment, it means that the liquid crystal in the display screen module of the streaming media rearview mirror may be inactivated due to low temperature, resulting in a slow response, and the streaming media rearview mirror may have a low-temperature smear phenomenon. When the streaming media rearview mirror has a low-temperature smear, it will affect the user's observation of the situation behind the vehicle, thereby reducing the user experience.

[0096] Since the liquid crystal does not need to be flipped in the reflector mode, when the streaming media rearview mirror is in a preset temperature environment, the reflector mode will not be affected by the activity of the liquid crystal. Therefore, the streaming media rearview mirror can be controlled to be in the reflector mode.

[0097] In this case, when the streaming media rearview mirror is in a preset temperature environment, the streaming media rearview mirror is controlled to start the reflector mode, so that the working mode of the streaming media rearview mirror is to reflect the environment behind the vehicle through the optical reflection principle. This will not affect the user's normal use of the streaming media rearview mirror, thereby improving the user experience.

[0098] Specifically, the operation of controlling the streaming media rearview mirror to start the reflector mode may be: adjusting the transmittance of the dimming glass to the first transmittance and adjusting the reflectance of the dimming glass to the first reflectance.

[0099] The dimming glass can be Figure 1 The dimming glass shown in the embodiment covers the display screen module. Optionally, the dimming glass can be an LC lens with adjustable reflectivity.

[0100] The first transmittance is the minimum transmittance of the dimming glass, and the first reflectance is the maximum reflectance of the dimming glass. For example, the first transmittance is 10%, and the first reflectance is 100%. It should be understood that when the dimming glass is at the minimum transmittance and the maximum reflectance, the power supply to the dimming glass is disconnected, that is, no voltage is applied to the dimming glass at this time.

[0101] In an embodiment of the present application, the transmittance and reflectance of the dimming glass can be adjusted within a certain range. The greater the transmittance of the dimming glass, the clearer the image displayed on the display screen module. The smaller the transmittance of the dimming glass, the less light that passes through the dimming glass on the image displayed on the display screen module, and the blurrier or less the image displayed on the display screen module. The smaller the reflectivity of the dimming glass, the less the dimming glass reflects the incident light, that is, the less it reflects the environment behind the vehicle. The greater the reflectivity of the dimming glass, the more the dimming glass reflects the incident light, that is, the more it reflects the environment behind the vehicle.

[0102] Since the reflector mode reflects the environment behind the vehicle through the principle of optical reflection, the image displayed by the display module does not need to be displayed. Therefore, the transmittance of the dimming glass can be adjusted to the lowest, so that the transmittance of the image displayed by the display module is the lowest. In addition, the reflectivity of the dimming glass is adjusted to the highest, so that the dimming glass can realize the basic reflection principle, thereby reflecting the environment behind the vehicle.

[0103] In this case, by adjusting the transmittance of the dimming glass to the first transmittance and the reflectivity of the dimming glass to the first reflectivity, the dimming glass can display the image of the display module without being transmitted and can reflect the environment behind the vehicle, thereby turning on the reflector mode.

[0104] It is worth noting that before step 401, it is also possible to determine whether the streaming media rearview mirror is in a preset temperature environment.

[0105] Optionally, the target temperature of the streaming media rearview mirror is obtained; when the target temperature is less than a first temperature threshold, it is determined that the streaming media rearview mirror is in a preset temperature environment; when the target temperature is greater than or equal to the first temperature threshold, it is determined that the streaming media rearview mirror is not in a preset temperature environment.

[0106] The target temperature is the temperature of the streaming media rearview mirror collected at the current moment.

[0107] In the embodiment of the present application, a temperature sensor, such as a thermistor sensor, may be configured in the streaming media rearview mirror. For example, the temperature sensor may be attached to the display screen module to detect the temperature, thereby more accurately detecting the temperature of the rearview mirror.

[0108] The first temperature threshold can be set in advance, and the first temperature threshold can be set to be relatively small. In the embodiment of the present application, the first temperature threshold can be set according to the activity of the liquid crystal at different temperatures. As an implementation, the first temperature threshold can be the critical temperature when the liquid crystal is inactivated. For example, the first temperature threshold is -12°C (degrees Celsius).

[0109] When the target temperature is lower than the first temperature threshold, it means that the target temperature is low, or the target temperature is lower than the temperature at which the liquid crystal is inactivated. Then the liquid crystal in the streaming media rearview mirror may respond slowly when powered on, and the streaming media rearview mirror may exhibit low-temperature ghosting. Therefore, it is determined that the streaming media rearview mirror is in a preset temperature environment.

[0110] When the target temperature is greater than or equal to the first temperature threshold, it means that the target temperature is relatively high, or the target temperature is greater than the temperature when the liquid crystal is inactivated, which means that the target temperature is the temperature when the liquid crystal is normally active, so there will be no low-temperature ghosting problem. Therefore, it is determined that the streaming media rearview mirror is not in the preset temperature environment.

[0111] Step 402: Increase the power of the backlight and control the display screen module to display a preset picture, so that the heat emitted by the backlight can heat up the streaming media rearview mirror, and the preset picture can block the light emitted by the backlight.

[0112] In the embodiment of the present application, the preset picture is a picture that can block the light emitted by the backlight. The preset picture can be set in advance. As an implementation method, the preset picture can be set to a pure color picture, for example, the preset picture can be a pure black picture.

[0113] Increasing the power of the backlight will make the backlight emit stronger light, so the heat emitted will also increase. Therefore, increasing the power of the backlight can heat up the streaming media rearview mirror through the heat emitted by the backlight.

[0114] After increasing the backlight power, the backlight brightness will be higher. The minimum light transmittance of dimming glass (for example, 10%) does not mean that no light can pass through. It will pass through some light. Therefore, the stronger the light emitted by the backlight, the stronger the light passing through the dimming glass will be. This will affect the normal use of the reflector mode by the user, that is, the environment behind the vehicle cannot be clearly seen. Therefore, while increasing the backlight power, the display module can also be controlled to display the preset screen.

[0115] In this way, the backlight can be used to heat up the streaming media rearview mirror without affecting the user's normal use of the streaming media rearview mirror, thereby solving the problem of ghosting of the streaming media rearview mirror in a low temperature environment while ensuring the normal use of the streaming media rearview mirror, thereby improving the user experience.

[0116] It should be understood that when the display screen module is controlled to display a preset image, it is equivalent to pausing the display of the image captured by the rear camera of the vehicle.

[0117] Optionally, the operation of increasing the power of the backlight may be implemented in the following two possible ways.

[0118] In a first possible implementation manner, the power of the backlight is adjusted to a first power.

[0119] The first power is the maximum power of the backlight.

[0120] In this case, the power of the backlight is adjusted to the maximum power that the backlight can bear in a short period of time, that is, the backlight is in a high power consumption mode in a short period of time. Therefore, the backlight can emit more heat in a short period of time, thereby allowing the streaming media rearview mirror to heat up quickly.

[0121] In this way, by adjusting the power of the backlight to the first power, the streaming media rearview mirror can be quickly heated up, thereby shortening the heating time of the streaming media rearview mirror and further improving the heating efficiency of the streaming media rearview mirror.

[0122] A second possible implementation is to respond to a start instruction for the streaming media display mode, determine a target brightness of the display screen module based on a target temperature; determine a second power of the backlight based on the target brightness; and adjust the power of the backlight to the second power.

[0123] The streaming media display mode is a mode that can display the image behind the vehicle, that is, the above Figure 2 Streaming media display mode shown in the embodiment. In the streaming media display mode, the image behind the vehicle is collected by the camera behind the vehicle, and then the image behind the vehicle collected by the camera is displayed by the display screen module, so that the user can observe the situation behind the vehicle.

[0124] The start instruction of the streaming media display mode is used to instruct to start the streaming media display mode. Optionally, the start instruction of the streaming media display mode can be triggered by the user. For example, the user can trigger the start instruction of the streaming media display mode by clicking, sliding, somatosensory, voice, etc. As an implementation, a switch for turning on the streaming media display mode can be configured on the streaming media rearview mirror. When the user clicks the switch, the start instruction of the streaming media display mode can be triggered.

[0125] The target brightness is greater than the rated brightness of the display module, and the rated brightness is the brightness that matches the current environment of the streaming media rearview mirror. At present, all streaming media rearview mirrors have a brightness adaptation function, that is, the brightness of the streaming media rearview mirror can be adaptively adjusted according to the environment to provide users with a more appropriate display brightness. In this case, the rated brightness can be the brightness determined according to the current environment after the streaming media rearview mirror is turned on. When the streaming media rearview mirror does not have a brightness adaptation function, the rated brightness can be the default brightness at the start of the streaming media rearview mirror.

[0126] The second power is greater than the power of the backlight of the display screen module at rated brightness.

[0127] In this case, when the user needs to forcibly turn on the streaming media display mode, the display screen module does not execute the normal brightness, but uses a higher brightness to accelerate the temperature rise, that is, the purpose of heating the streaming media rearview mirror is achieved by increasing the brightness of the display screen module. In this way, it is possible to achieve the purpose of heating the streaming media rearview mirror while meeting the user's demand for the streaming media display mode, thereby improving the user experience.

[0128] The operation of determining the target brightness of the display screen module based on the target temperature may be: based on the target temperature, acquiring the target brightness of the display screen module from the first corresponding relationship.

[0129] The first corresponding relationship is the corresponding relationship between the temperature of the rearview mirror and the brightness of the display screen module. The first corresponding relationship includes multiple temperatures and multiple brightnesses, wherein the multiple temperatures correspond to the multiple brightnesses one by one, that is, for any one of the multiple temperatures, each temperature corresponds to a brightness.

[0130] For example, the following Table 1 is an example of the first correspondence, see Table 1, Table 1 includes multiple temperatures and multiple brightnesses. The multiple temperatures are different temperature environments where the display screen module is located, and the multiple brightnesses refer to the brightness that the display screen module should display in different temperature environments in order to heat up the streaming media rearview mirror. For example, the target temperature of the streaming media rearview mirror is -25°C. From the first correspondence shown in Table 1 below, it can be obtained that the target brightness of the display screen module is the rated brightness + 50nit (nits).

[0131] Table 1

[0132] temperature brightness -30℃ Maximum brightness (e.g. 500nit) -25℃ Rated brightness +50nit -20℃ Rated brightness +30nit -10℃ Rated brightness (e.g. 300nit)

[0133] The embodiment of the present application only uses Table 1 as an example to illustrate the first corresponding relationship, and does not constitute a limitation to the embodiment of the present application.

[0134] In addition, in the first correspondence, the lower the temperature of the streaming media rearview mirror, the more serious the drag of the streaming media rearview mirror, and the corresponding brightness in the first correspondence can be set higher to increase the temperature as quickly as possible through high-brightness display. When the temperature of the streaming media rearview mirror is low, the drag is not obvious, and the rated brightness can be slightly brightened to achieve the purpose of heating.

[0135] In this way, the brightness of the display screen module is determined according to the temperature of the streaming media rearview mirror, which can save electricity while ensuring that the streaming media rearview mirror is heated.

[0136] Among them, the operation of determining the second power of the backlight based on the target brightness can be: determining the required luminous flux based on the target brightness and the screen area of ​​the display module; obtaining the luminous effect of the backlight; dividing the required luminous flux by the luminous effect of the backlight to obtain the second power of the backlight.

[0137] The second power of the backlight is the power required for the display screen module to reach the target brightness.

[0138] For example, the target brightness is 500nit and the screen area of ​​the display module is 0.01m 2 , the backlight efficiency is 50.

[0139] The required luminous flux is 500×0.01=5, and the subsequent calculation results in the second power of the backlight being 5÷50=0.1 W (watt).

[0140] Optionally, during the process of the rearview mirror heating up, a reminder message can be superimposed on the preset screen to remind the user that the current temperature of the rearview mirror is too low and the display will be restored later.

[0141] It is worth noting that the following operations can also be performed after step 402: based on the target temperature, determine the target time for the streaming media rearview mirror to rise from the target temperature to the second temperature threshold; control the streaming media rearview mirror to highlight the target reminder information on the preset screen.

[0142] The second temperature threshold can be set in advance, and the second temperature threshold can be set larger to ensure that the problem of smearing does not occur after the temperature of the streaming media rearview mirror rises to the second temperature threshold. In an embodiment of the present application, the second temperature threshold is greater than or equal to the first temperature threshold. For example, when the first temperature threshold can be set to -12°C, the second temperature threshold can be set to -10°C.

[0143] The target reminder information includes target duration or target temperature and target duration.

[0144] In this case, the time it takes to return to normal temperature can be displayed during the heating process of the streaming media rearview mirror, or the current low temperature of the streaming media rearview mirror and the time it takes to return to normal temperature can be displayed. In this way, the user can know how long it will take for the streaming media rearview mirror to return to normal temperature, and how long it will take for the streaming media display mode to be used, thereby improving the user experience.

[0145] In addition, since the transmittance of the dimming glass is low after the power is turned off, the bright text can pass through the dimming glass, but the dark black background is not easy to be penetrated, so the target reminder information can be highlighted on the preset screen. In this way, by controlling the streaming media rearview mirror to highlight the target reminder information on the preset screen, the user can clearly see the displayed target reminder information.

[0146] Among them, based on the target temperature, the operation of determining the target time for the streaming media rearview mirror to rise from the target temperature to the second temperature threshold may be: based on the target temperature, determining the target time from the second corresponding relationship.

[0147] The second correspondence is the correspondence between the temperature of the streaming media rearview mirror and the temperature recovery time, and the temperature recovery time is the time it takes for the streaming media rearview mirror to rise from different temperatures to the second temperature threshold. The second correspondence includes multiple temperatures and multiple time periods, where the multiple temperatures refer to the different temperature environments in which the streaming media rearview mirror is located, and the multiple time periods refer to the time it takes for the streaming media rearview mirror to recover from the corresponding low temperature to the second temperature threshold. The multiple temperatures correspond to the multiple time periods one by one, that is, any one of the multiple temperatures has a corresponding time period.

[0148] In the embodiment of the present application, the second corresponding relationship can be obtained by pre-calibration. That is, the technician can control the streaming media rearview mirror to be in different temperature environments through experiments, and perform the operation of the above step 402 at different temperatures to make the streaming media rearview mirror heat up, and record the time it takes for the streaming media rearview mirror to rise from different temperatures to the second temperature threshold, so as to obtain the second corresponding relationship.

[0149] For example, the following Table 2 is an example of the second correspondence, referring to Table 2, which includes multiple temperatures and multiple durations. The multiple temperatures correspond to the multiple durations one by one. For example, the target temperature of the streaming media rearview mirror is -25°C, and the target duration can be obtained as 12 minutes from the second correspondence shown in Table 2.

[0150] Table 2

[0151] temperature Temperature recovery time -30℃ 15min -2℃ 12min -20℃ 8min …… ……

[0152] The embodiment of the present application only uses Table 2 as an example to illustrate the second corresponding relationship, and does not constitute a limitation to the embodiment of the present application.

[0153] Optionally, the streaming media rearview mirror can be controlled to display target reminder information within the display duration.

[0154] The display duration can be set in advance, and the display duration can be set larger.

[0155] In this case, the target reminder information is displayed within the display time by controlling the streaming media rearview mirror to ensure that the user can see the target reminder information.

[0156] In an embodiment of the present application, after controlling the streaming media rearview mirror to highlight the target reminder information on the preset screen, the following steps (1) to (2) can also be performed during the heating process of the streaming media rearview mirror.

[0157] (1) When the temperature of the streaming media rearview mirror rises from the target temperature to the second temperature threshold, the temperature of the streaming media rearview mirror is detected.

[0158] During the process of the streaming media rearview mirror rising from the target temperature to the second temperature threshold, the temperature of the streaming media rearview mirror can be continuously detected by the temperature sensor to obtain the real-time temperature during the temperature rising process, and determine whether the temperature of the streaming media rearview mirror has returned to normal temperature based on this.

[0159] Optionally, the operation of step (1) may be: in the process of the streaming media rearview mirror rising from the target temperature to the second temperature threshold, detecting the temperature of the streaming media rearview mirror at preset time intervals.

[0160] The preset duration can be set in advance, and the preset duration can be set much smaller than the target duration. For example, if the target duration is 10 minutes, the preset duration can be set to 10 seconds.

[0161] (2) displaying the detected temperature of the streaming media rearview mirror; and / or, based on the temperature ratio between the detected temperature of the streaming media rearview mirror and a second temperature threshold, displaying a temperature rise progress bar.

[0162] The temperature rise progress bar is used to indicate the temperature rise progress of the streaming media rearview mirror.

[0163] In the above step (2), by displaying the detected temperature of the streaming media rearview mirror, the user can timely know the real-time temperature of the streaming media rearview mirror during the heating process of the streaming media rearview mirror, thereby improving the user experience. In addition, by displaying a temperature rising progress bar, the user can timely know the temperature rising progress of the streaming media rearview mirror, thereby improving the user experience.

[0164] Optionally, the detected temperature of the streaming media rearview mirror can be displayed in the form of an alarm prompt or a temperature icon.

[0165] For example, the detected temperature of the streaming media rearview mirror can be displayed by flashing at a target frequency, so that the user can pay more attention to the real-time temperature of the streaming media rearview mirror, and thus obtain the real-time temperature of the streaming media rearview mirror more promptly, thereby improving the user experience.

[0166] For example, Figure 5This is a schematic diagram of the interface of a display screen of a streaming media rearview mirror provided in an embodiment of the present application. Figure 5 , Figure 5 The streaming media rearview mirror 501 includes a temperature display area 502 and a temperature rise progress bar 503. The temperature display area 502 is used to display the detected temperature of the streaming media rearview mirror. In this way, the user can see the temperature and the temperature rise progress bar displayed on the display screen to know the current temperature rise progress of the streaming media rearview mirror and the real-time temperature of the streaming media rearview mirror.

[0167] Optionally, a time countdown can be displayed while the temperature of the streaming media rearview mirror rises.

[0168] The duration countdown is used to indicate how long it will take for the temperature of the streaming media rearview mirror to return to normal temperature, that is, the remaining recovery time of the streaming media rearview mirror temperature.

[0169] In this case, by displaying the time countdown, the user can more intuitively know how long it will take for the temperature of the streaming media rearview mirror to rise to the normal temperature, and how long it will take for the streaming media display mode of the streaming media rearview mirror to be used. In addition, since users pay more attention to the time factor than the temperature, by displaying the time countdown, the user's needs can be met, thereby improving the user experience.

[0170] It is worth noting that through the above steps 401 and 402, the backlight can emit heat to heat up the streaming media rearview mirror, so that the temperature of the streaming media rearview mirror returns to normal temperature. In the embodiment of the present application, after the temperature of the streaming media rearview mirror returns to normal temperature, the streaming media rearview mirror can also be controlled to turn on the streaming media display mode.

[0171] Specifically, when the temperature of the streaming media rearview mirror rises to a second temperature threshold, the display screen module is controlled to display a target image; the transmittance of the dimming glass is adjusted to a second transmittance, and the reflectivity of the dimming glass is adjusted to a second reflectivity.

[0172] The target image is the image captured by the camera behind the vehicle.

[0173] The second light transmittance is the maximum light transmittance of the dimming glass, and the second reflectivity is the minimum reflectivity of the dimming glass.

[0174] In this case, it is equivalent to controlling the display screen module to display the image captured by the camera behind the vehicle. Since the reflectivity of the dimming glass in the reflector mode is the highest and the transmittance is the lowest, the image displayed by the display screen module will not be visible. In order to see the image displayed by the display screen module, the reflectivity of the dimming glass can be adjusted to the lowest and the transmittance to the highest, that is, the transmittance of the dimming glass can be adjusted to the second transmittance and the reflectivity can be adjusted to the second reflectivity.

[0175] It is worth noting that in the embodiment of the present application, power can be supplied to the display screen module, so that the transmittance of the dimming glass is the highest and the reflectivity is the lowest, that is, the streaming media display mode is turned on.

[0176] For ease of understanding, now combined Figure 6 The streaming media rearview mirror heating method provided in the embodiment of the present application is exemplarily described. Figure 6 This is a flow chart of another method for heating a streaming media rearview mirror provided in an embodiment of the present application. Figure 6 , Figure 6 The following steps 601-609 are included.

[0177] Step 601: Obtain the target temperature of the streaming media rearview mirror.

[0178] Step 602: Determine whether the target temperature is less than the first temperature threshold. If the target temperature is less than the first temperature threshold, execute the following step 603; if the target temperature is greater than or equal to the first temperature threshold, continue to maintain the current working mode.

[0179] Step 603: Control the streaming media rearview mirror to start the reflector mode.

[0180] Step 604: Increase the power of the backlight and control the display screen module to display a preset image.

[0181] Step 605: Highlight the target reminder information on the preset screen.

[0182] Step 606: While the streaming media rearview mirror is heating up, detect the temperature of the streaming media rearview mirror.

[0183] Step 607: Determine whether the temperature of the streaming media rearview mirror reaches the second temperature threshold. If the temperature of the streaming media rearview mirror reaches the second temperature threshold, execute the following step 609; if the temperature of the streaming media rearview mirror does not reach the second temperature threshold, execute the following step 608.

[0184] Step 608: Display the temperature of the streaming media rearview mirror and / or display a temperature rising progress bar.

[0185] Step 609: Control the streaming media rearview mirror to start the streaming media display mode.

[0186] In an embodiment of the present application, the streaming media rearview mirror includes a display screen module, and the display screen module includes a backlight. When the streaming media rearview mirror controller detects that the streaming media rearview mirror is in a preset temperature environment, it can first control the streaming media rearview mirror to start the reflector mode, which is a mode that reflects the environment behind the vehicle through the optical reflection principle, that is, when the streaming media rearview mirror has a low temperature drag problem, the user can observe the reflected environment behind the vehicle in the reflector mode. Then, the power of the backlight is increased and the display screen module is controlled to display a preset picture. Since the brightness of the backlight will be higher after the power of the backlight is increased, the light of the backlight passing through the display screen module will affect the normal use of the reflector mode. Therefore, the power of the backlight can be increased while the display screen module can be controlled to display a preset picture, such as displaying a pure black picture. Thereby, the heat emitted by the backlight can be used to heat up the streaming media rearview mirror, and the light emitted by the backlight can be blocked by the preset picture, so that the streaming media rearview mirror can be heated up by the heat emitted by the backlight without affecting the normal use of the rearview mirror by the user. In this way, the problem of ghosting in the streaming media rearview mirror under special temperature environments can be solved, thereby improving the user experience.

[0187] Figure 7 : is a schematic diagram of a structure of a streaming media rearview mirror heating device provided in an embodiment of the present application.

[0195] Optionally, the temperature increasing module 702 is used for:

[0196] In response to a start instruction for a streaming media display mode, a target brightness of the display screen module is determined based on a target temperature. The streaming media display mode is a mode capable of displaying an image behind the vehicle. The target brightness is greater than a rated brightness of the display screen module. The rated brightness is a brightness that matches the environment in which the streaming media rearview mirror is currently located. The target temperature is the temperature of the streaming media rearview mirror collected at the current moment.

[0197] Based on the target brightness, determining a second power of the backlight;

[0198] The power of the backlight is adjusted to a second power, where the second power is greater than the power of the backlight when the display screen module is at rated brightness.

[0201] Optionally, the device further comprises:

[0202] A second determination module is used to determine, based on the target temperature, a target time for the streaming media rearview mirror to rise from the target temperature to a second temperature threshold, the second temperature threshold is greater than or equal to the first temperature threshold, and the target temperature is the temperature of the streaming media rearview mirror collected at the current moment;

[0203] The first display module is used to control the streaming media rearview mirror to highlight the target reminder information on the preset screen, where the target reminder information includes the target duration or the target temperature and the target duration.

[0204] Optionally, the device further comprises:

[0205] A detection module, used for detecting the temperature of the streaming media rearview mirror when the streaming media rearview mirror rises from a target temperature to a second temperature threshold;

[0206] The second display module is used to display the detected temperature of the streaming media rearview mirror; and / or, based on the temperature ratio between the detected temperature of the streaming media rearview mirror and the second temperature threshold, display a temperature rise progress bar, wherein the temperature rise progress bar is used to indicate the temperature rise progress of the streaming media rearview mirror.

[0210] In an embodiment of the present application, the streaming media rearview mirror includes a display screen module, and the display screen module includes a backlight. When it is detected that the streaming media rearview mirror is in a preset temperature environment, the streaming media rearview mirror can be controlled to start the reflector mode, which is a mode that reflects the environment behind the vehicle through the optical reflection principle, that is, when the streaming media rearview mirror has a low temperature drag problem, the user can observe the reflected environment behind the vehicle in the reflector mode. Then the power of the backlight is increased and the display screen module is controlled to display a preset picture. Since the brightness of the backlight will be higher after the power of the backlight is increased, the light of the backlight will affect the normal use of the reflector mode through the display screen module. Therefore, the power of the backlight can be increased while the display screen module can be controlled to display a preset picture, such as displaying a pure black picture. Thereby, the heat emitted by the backlight can be used to heat up the streaming media rearview mirror, and the light emitted by the backlight can be blocked by the preset picture, so that the streaming media rearview mirror can be heated up by the heat emitted by the backlight without affecting the normal use of the rearview mirror by the user. In this way, the problem of ghosting in the streaming media rearview mirror under special temperature environments can be solved, thereby improving the user experience.
