Description
Technical Field
[0001] This application relates to the field of vehicle technology, and in particular to a method, device and vehicle for heating a streaming rearview mirror. Background Technology
[0002] With technological advancements, vehicle technology is becoming increasingly sophisticated. Currently, more and more vehicles are equipped with streaming rearview mirrors, which indirectly present the rear view through images captured by cameras and displays. Streaming rearview mirrors are divided into single-mode and dual-mode types. A single-mode streaming rearview mirror is a pure display screen that can only observe the camera's image. A dual-mode streaming rearview mirror has a lens covering the display screen. Light from the display screen can pass through the lens, and when the display screen is turned off, the lens can be used as a reflector. In other words, it can both observe the camera's image and reflect the reflected image.
[0003] However, the display screen of streaming rearview mirrors is generally an LCD screen, and the activity of liquid crystals decreases in low temperature environments. Therefore, the image on the display screen will have a delay and ghosting problem, which will reduce the user experience. Summary of the Invention
[0004] This application provides a method, device, vehicle, and storage medium for heating a streaming media rearview mirror. When the streaming media rearview mirror is in a preset temperature environment, the backlight power is increased to dissipate heat, thereby heating the mirror and eliminating motion blur that occurs at low temperatures, thus improving the user experience. The technical solution is as follows:
[0005] Firstly, a method for heating a streaming rearview mirror is provided, the method comprising:
[0006] When the streaming rearview mirror is in a preset temperature environment, the streaming rearview mirror is controlled to start the reflector mode. The streaming rearview mirror includes a display module, the display module includes a backlight, and the reflector mode is a mode that reflects the environment behind the vehicle through the principle of optical reflection.
[0007] The power of the backlight is increased and the display module is controlled to display a preset image, 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 blocked by the preset image.
[0008] In this application, the streaming rearview mirror includes a display module, which includes a backlight. When the streaming rearview mirror is detected to be in a preset temperature environment, it can first be controlled to activate a reflector mode. This reflector mode reflects the environment behind the vehicle using optical reflection principles. That is, when the streaming rearview mirror exhibits low-temperature ghosting, the user can observe the reflected environment behind the vehicle in reflector mode. Then, the backlight power is increased, and the display module is controlled to display a preset image. Since increasing the backlight power also increases its brightness, the light from the backlight passing through the display module can affect the normal use of the reflector mode. Therefore, while increasing the backlight power, the display module can also be controlled to display a preset image, such as a pure black screen. This allows the streaming rearview mirror to heat up while the heat emitted by the backlight is used to block the light emitted by the backlight, achieving the goal of heating the streaming rearview mirror through heat dissipation without affecting the user's normal use of the rearview mirror.

[0067] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.
[0068] It should be understood that "multiple" as mentioned in this application refers to two or more. In the description of this application, unless otherwise stated, " / " indicates "or," for example, A / B can mean A or B; "and / or" in this document is merely a description of the relationship between related objects, indicating that three relationships can exist, for example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Furthermore, to facilitate a clear description of the technical solutions of this application, the terms "first," "second," etc., are used to distinguish identical or similar items with essentially the same function and effect. Those skilled in the art will understand that the terms "first," "second," etc., do not limit the quantity or execution order, and that "first," "second," etc., do not necessarily imply differences.
[0069] Before describing the heating method for the streaming media rearview mirror provided in the embodiments of this application, the structure of the streaming media rearview mirror involved in the embodiments of this application will be described in detail.
[0070] For example, Figure 1 This is a schematic diagram of the structure of a streaming media rearview mirror provided in an embodiment of this application. See also... Figure 1 The streaming media rearview mirror includes a display module 101, a dimming glass 102, and a cover glass 103.
[0071] Among them, when the streaming rearview mirror is used as Figure 1 When placed horizontally as shown, the dimming glass 102 covers the display module 101 to adjust the light transmittance of the display module 101. It should be noted that the dimming glass 102 is a type of glass whose transparency can be changed electronically (by voltage). Specifically, the light transmittance of the dimming glass 102 is usually directly related to the voltage applied to it; that is, when there is no voltage, the dimming glass 102 is opaque with very low light transmittance close to zero. As the voltage increases, the light transmittance of the dimming glass 102 increases accordingly.
[0072] The cover glass 103 covers the dimming glass 102 to protect the dimming glass 102 and the display module 101 from damage.
[0073] Generally, dimming glass that can adjust its transmittance and reflectance can include electrochromic glass, suspended particle devices, liquid crystal dimming glass, and thermochromic dimming glass. In the embodiments of this application, the dimming glass can be liquid crystal dimming glass. It can change its transmittance and reflectance by changing the arrangement of liquid crystal molecules through voltage.
[0074] As an example, the dimming glass 102 can be a liquid crystal lens (LC lens) with adjustable reflectivity. The LC lens includes a polarizer, liquid crystal glass, and an RPM film (Reflective Polarization Modulation).
[0075] For example, Figure 2 This is a schematic diagram illustrating the working principle of a streaming media rearview mirror provided in an embodiment of this application. See also... Figure 2 The streaming media rearview mirror includes a display 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 this embodiment, the streaming media rearview mirror includes a streaming media display mode and a reflective mirror mode. The streaming media display mode displays an image of the area behind the vehicle using the display module 201. The reflective mirror mode reflects the environment behind the vehicle using optical reflection principles.
[0077] It is worth noting that users can manually switch between the two modes using a physical button on the streaming rearview mirror or a virtual button on the vehicle's central control screen; this embodiment does not limit this. Additionally, the vehicle can automatically switch between the two modes based on its status (e.g., reversing, high-speed driving).
[0078] like Figure 2 As shown in (a), when the display module 201 is powered on, the liquid crystal in the liquid crystal glass 204 is simultaneously powered on and flipped, so that the transmittance of the LC lens 202 is maximized and the reflectance is minimized. After the incident light passes through the polarizer 203, the reflectance is 50%, and after passing through the RPM film 205, the reflectance is 10%.
[0079] In this scenario, the streaming rearview mirror is in streaming display mode, which means it displays an image of the area behind the vehicle via the display module 201. The LC lens 202 has the lowest reflectivity and the highest transmittance, allowing the image displayed by the display module 201 to pass through the LC lens 202 and be seen by the user.
[0080] like Figure 2As shown in (b), when the display module 201 is not powered on, that is, when the display module 201 is off, the liquid crystal arrangement state in the clamping liquid crystal glass 204 does not change, resulting in low transmittance and high reflectivity of the LC lens 202. In this case, the streaming media rearview mirror is in reflective mirror mode, that is, the mode of reflecting the environment behind the vehicle through the principle of optical reflection. By increasing the reflectivity and reducing the transmittance of the LC lens 202, 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 module in the streaming rearview mirror.
[0082] For example, Figure 3 This is a schematic diagram of the structure of a display module provided in an embodiment of this application. See also... Figure 3 The display module may include a backlight 301 and a liquid crystal layer 302 (i.e., a liquid crystal display).
[0083] The backlight 301 provides background light for the display module. By adjusting the brightness of the backlight 301, users can clearly see the image displayed on the display module under different lighting conditions. Optionally, the backlight 301 can be located at the top of the display module to provide light to the display area below. Of course, the backlight 301 can also be located at the bottom, left, or right side of the display module; this embodiment does not limit the location.
[0084] As an example, the backlight 301 can be any one of a light-emitting diode (LED), an organic light-emitting diode (OLED), or a micro light-emitting diode (Micro LED). Of course, the backlight can also be other types of lamps, and this application embodiment does not limit this.
[0085] The liquid crystal layer 302 is used to display images, which can realize the function of a streaming media rearview mirror by displaying images captured by a camera at the rear of the vehicle.
[0086] It's important to note that the core of liquid crystal imaging is the "change in the alignment direction of liquid crystal molecules," that is, the movement of liquid crystal molecules. However, liquid crystal materials are very sensitive to ambient temperature. The lower the temperature, the slower the liquid crystal molecules flip, which means that the response time of the liquid crystal display screen will be longer, resulting in ghosting and affecting the display effect.
[0087] Therefore, this application provides a method for heating a streaming media rearview mirror, which can be applied to scenarios where the streaming media rearview mirror is in a preset temperature environment.
[0088] Specifically, the system detects the temperature of the streaming rearview mirror. If the mirror is detected to be within a preset temperature range, it first activates the reflector mode, which uses optical reflection to reflect the image behind the vehicle for normal operation. Then, the backlight power is increased to warm the mirror. Increasing the backlight power can negatively impact the reflector mode's performance; therefore, the display module is also controlled to show a preset image to block the backlight's light.
[0089] In this way, by using the heat emitted by the backlight to heat up the streaming rearview mirror, and simultaneously using a preset image to block the light emitted by the backlight, the streaming rearview mirror can be heated by the backlight without affecting the user's normal use of the rearview mirror. This solves the problem of ghosting in special temperature environments and improves the user experience.
[0090] The following is a detailed explanation of the streaming media rearview mirror heating method provided in the embodiments of this application.
[0091] Figure 4 This is a flowchart illustrating a method for heating a streaming rearview mirror according to an embodiment of this application. This method can be applied to vehicles equipped with streaming rearview mirrors and can be applied to the vehicle's streaming rearview mirror controller (RMC). See also... Figure 4 The method includes steps 401 and 402.
[0092] Step 401: When the streaming rearview mirror is in a preset temperature environment, control the streaming rearview mirror to start the reflector mode. The streaming rearview mirror includes a display module, which includes a backlight. The reflector mode is a mode that reflects the environment behind the vehicle through the principle of optical reflection.
[0093] Streaming rearview mirrors can provide the above Figure 1 The streaming rearview mirror shown in the embodiment. The display module can be as described above. Figure 3 The display module shown in the embodiment includes a backlight.
[0094] The preset temperature environment can be defined in advance by technicians. For example, technicians can predefine a temperature range, and the streaming rearview mirror is considered to be in the preset temperature environment when it is within this temperature range. In this embodiment, the preset temperature environment can be a low-temperature environment. For example, the temperature range set by the technicians can be the temperature range at which the streaming rearview mirror deactivates at low temperatures. Therefore, when the streaming rearview mirror is within this temperature range, it can be considered that the streaming rearview mirror is in a low-temperature environment.
[0095] In this scenario, if the streaming rearview mirror is operating at a preset temperature, the liquid crystal in the display module may become inactive due to low temperatures, resulting in a slower response and potentially causing low-temperature ghosting. This low-temperature ghosting can impair the user's ability to see what's behind the vehicle, thus reducing the user experience.
[0096] Since the liquid crystal does not need to flip in the reflector mode, the reflector mode is not affected by the activity of the liquid crystal when the streaming media rearview mirror is in a preset temperature environment. Therefore, the streaming media rearview mirror can be controlled to be in reflector mode.
[0097] In this scenario, with the streaming rearview mirror operating at a preset temperature, the mirror's reflective mode is activated, allowing it to reflect the environment behind the vehicle using optical reflection. This ensures normal use of the mirror without affecting the user experience, thus enhancing the user experience.
[0098] Specifically, the operation to control the streaming media rearview mirror to activate the reflector mode can be: adjusting the light transmittance of the dimming glass to a first light transmittance and adjusting the reflectivity of the dimming glass to a first reflectivity.
[0099] The dimming glass can be the above Figure 1 The dimming glass shown in the embodiment covers the display 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 its minimum transmittance and maximum reflectance, the power supply to the dimming glass is disconnected, meaning that no voltage is applied to the dimming glass at this time.
[0101] In this embodiment, the transmittance and reflectance of the dimming glass can be adjusted within a certain range. The higher the transmittance of the dimming glass, the clearer the image displayed on the screen module. The lower the transmittance of the dimming glass, the less light passes through it, resulting in a blurrier or less visible image. The lower the reflectance of the dimming glass, the less incident light it reflects, meaning less reflection of the environment behind the vehicle. The higher the reflectance of the dimming glass, the more incident light it reflects, meaning more reflection of the environment behind the vehicle.
[0102] Since the reflector mode reflects the environment behind the vehicle through optical reflection, the image displayed on the screen module does not need to be shown. Therefore, the transmittance of the dimming glass can be adjusted to the lowest possible level, minimizing the transmittance of the image displayed on the screen module. Conversely, the reflectivity of the dimming glass can be adjusted to the highest possible level, enabling it to achieve basic reflection and thus reflect the environment behind the vehicle.
[0103] In this case, by adjusting the light transmittance of the dimming glass to the first light transmittance and the reflectivity of the dimming glass to the first reflectivity, the dimming glass can reflect the image of the display module without transmitting light through it, and can reflect the environment behind the vehicle, thereby enabling the mirror mode to be activated.
[0104] It is worth noting that before step 401, it can be determined whether the streaming rearview mirror is in a preset temperature environment.
[0105] Optionally, the target temperature of the streaming media rearview mirror is obtained; if the target temperature is less than a first temperature threshold, the streaming media rearview mirror is determined to be in a preset temperature environment; if the target temperature is greater than or equal to the first temperature threshold, the streaming media rearview mirror is determined not to be in a preset temperature environment.
[0106] The target temperature is the temperature of the streaming rearview mirror collected at the current moment.
[0107] In this embodiment, the streaming rearview mirror may be equipped with a temperature sensor, such as a thermistor sensor. For example, the temperature sensor can be attached to the display module to detect the temperature, thereby enabling more accurate detection of the rearview mirror temperature.
[0108] The first temperature threshold can be preset, and the first temperature threshold can be set to a relatively small value. In the embodiments of this application, the first temperature threshold can be set according to the activity of the liquid crystal at different temperatures. As one implementation, the first temperature threshold can be the critical temperature at which the liquid crystal deactivates. For example, the first temperature threshold is -12°C.
[0109] If the target temperature is lower than the first temperature threshold, it means that the target temperature is low, or that the target temperature is lower than the temperature at which the liquid crystal deactivates. In this case, 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] If the target temperature is greater than or equal to the first temperature threshold, it indicates that the target temperature is relatively high, or that the target temperature is greater than the temperature at which the liquid crystal deactivates. This means that the target temperature is the temperature at which the liquid crystal is normally active, and therefore there will be no low-temperature ghosting problem. Thus, 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 module to display a preset image, so that the heat emitted by the backlight can heat up the streaming media rearview mirror, and the preset image can block the light emitted by the backlight.
[0112] In this embodiment, the preset screen is a screen that can block the light emitted by the backlight. The preset screen can be preset; as one implementation, the preset screen can be set to a solid color screen, for example, a pure black screen.
[0113] Increasing the backlight power will make the backlight emit a stronger light, and thus increase the heat generated. Therefore, increasing the backlight power can cause the streaming rearview mirror to heat up due to the heat emitted by the backlight.
[0114] Increasing the backlight power results in higher brightness. However, the minimum light transmittance of the dimming glass (e.g., 10%) doesn't completely block all light; some light will pass through. Therefore, the stronger the backlight, the stronger the light transmitted through the dimming glass. This can interfere with the user's normal use of the reflector mode, making it difficult to see the reflected environment behind the vehicle. Therefore, increasing the backlight power can simultaneously control the display module to show a preset image.
[0115] In this way, the streaming rearview mirror can be heated by backlighting without affecting the user's normal use of the streaming rearview mirror. This solves the problem of ghosting in low-temperature environments while ensuring the normal use of the streaming rearview mirror, thereby improving the user experience.
[0116] It should be understood that when the control display module displays the preset image, it is equivalent to pausing the display of the image captured by the rear camera of the vehicle.
[0117] Alternatively, increasing the power of the backlight can be achieved in two possible ways.
[0118] The first possible implementation is to adjust the power of the backlight to the first power level.
[0119] The first power is the maximum power of the backlight.
[0120] In this scenario, the backlight power is adjusted to the maximum power it can withstand for a short period, effectively putting the backlight in a high-power mode for a short time. This allows the backlight to dissipate more heat in a short period, thus enabling the streaming 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 heat up quickly, thereby shortening the heating time of the streaming media rearview mirror and improving its heating efficiency.
[0122] The second possible implementation involves, in response to a command to start the streaming media display mode, determining the target brightness of the display module based on the target temperature; determining the second power of the backlight based on the target brightness; and adjusting the power of the backlight to the second power.
[0123] The streaming media display mode is a mode that can display images behind the vehicle, which is the one described above. Figure 2 The embodiment illustrates a streaming media display mode. In this mode, a camera behind the vehicle captures images of the area behind the vehicle, which are then displayed on a screen module, allowing the user to observe the situation behind the vehicle.
[0124] The command to activate the streaming media display mode is used to instruct the user to start the streaming media display mode. Optionally, the command to activate the streaming media display mode can be triggered by the user. For example, the user can trigger the command to activate the streaming media display mode through clicking, swiping, motion sensing, or voice control. As one implementation, the streaming media rearview mirror can be equipped with a switch to activate the streaming media display mode; when the user clicks this switch, the command to activate the streaming media display mode can be triggered.
[0125] The target brightness is greater than the rated brightness of the display module, which is the brightness matched to the current environment of the streaming rearview mirror. Currently, all streaming rearview mirrors have an adaptive brightness function, meaning the mirror's brightness can be adjusted according to the environment to provide a suitable display brightness for the user. In this case, the rated brightness is the brightness determined by the streaming rearview mirror based on the current environment after power-on. When the streaming rearview mirror does not have an adaptive brightness function, the rated brightness is the default brightness set at startup.
[0126] The second power is greater than the power of the backlight of the display module at its rated brightness.
[0127] In this scenario, where the user needs to force the streaming media display mode to be activated, the display module does not operate at normal brightness but instead uses higher brightness to accelerate heating. In other words, the purpose of heating the streaming media rearview mirror is achieved by increasing the brightness of the display module. This allows the user's need for streaming media display mode to be met while simultaneously heating the rearview mirror, thus improving the user experience.
[0128] The operation of determining the target brightness of the display module based on the target temperature can be as follows: based on the target temperature, obtain the target brightness of the display module from the first correspondence relationship.
[0129] The first correspondence is the relationship between the rearview mirror temperature and the brightness of the display module. The first correspondence includes multiple temperatures and multiple brightness levels, wherein each of the multiple temperatures corresponds to a specific brightness level.
[0130] For example, Table 1 below shows an example of the first correspondence. Table 1 includes multiple temperatures and multiple brightness levels. The multiple temperatures represent different temperature environments in which the display module operates, and the multiple brightness levels refer to the brightness that the display module should display under different temperature environments to heat up the streaming rearview mirror. For instance, if the target temperature of the streaming rearview mirror is -25℃, the target brightness of the display module can be obtained from the first correspondence shown in Table 1 as rated brightness + 50 nits.
[0131] Table 1
[0132] temperature brightness -30℃ Maximum brightness (e.g., 500 nits) -25℃ Rated brightness +50 nits -20℃ Rated brightness +30 nits -10℃ Rated brightness (e.g., 300 nits)
[0133] The embodiments of this application are merely illustrative examples of the first correspondence relationship described in Table 1 above, and do not constitute a limitation on the embodiments of this application.
[0134] Furthermore, in the first correspondence, the lower the temperature of the streaming rearview mirror, the more severe the ghosting. Therefore, the brightness corresponding to this lower temperature can be set higher to quickly raise the temperature through a high-brightness display. When the streaming rearview mirror is at a lower temperature, the ghosting is less noticeable, and a slight increase in brightness beyond the rated brightness can also achieve the same goal of raising the temperature.
[0135] Therefore, by determining the brightness of the display module based on the temperature of the streaming rearview mirror, energy can be saved while ensuring the streaming rearview mirror heats up.
[0136] The operation of determining the second power of the backlight based on the target brightness can be as follows: determine the required luminous flux based on the target brightness and the screen area of the display module; obtain the luminous efficacy of the backlight; divide the required luminous flux by the luminous efficacy of the backlight to obtain the second power of the backlight.
[0137] The second power of the backlight is the power required to make the display module reach the target brightness.
[0138] For example, the target brightness is 500 nits, and the screen area of the display module is 0.01m². 2 The backlight's luminous efficacy is 50.
[0139] The required luminous flux is 500 × 0.01 = 5, and the subsequent calculation yields the second power of the backlight as 5 ÷ 50 = 0.1 W (watts).
[0140] Optionally, during the rearview mirror heating process, a reminder message can be overlaid on a preset screen to remind the user that the rearview mirror temperature is currently too low and will be restored to normal shortly.
[0141] It is worth noting that after step 402, the following operations can also be performed: 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 preset, and the second temperature threshold can be set relatively high to ensure that the streaming rearview mirror does not exhibit motion blur after its temperature rises to the second temperature threshold. In this embodiment, 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℃, the second temperature threshold can be set to -10℃.
[0143] The target reminder information includes the target duration or the target temperature and target duration.
[0144] In this scenario, the streaming rearview mirror can display the time it takes to return to normal temperature during the heating process, or it can display the current low temperature of the streaming rearview mirror and the time it takes to return to normal temperature. This allows users to know how long it will take for the streaming rearview mirror to return to normal temperature, and thus how long it will take before they can use the streaming display mode, thereby improving the user experience.
[0145] Additionally, because the light transmittance of the dimming glass is low after power is off, bright, bright text can pass through it, but darker black backgrounds are not easily transmitted. Therefore, target reminder information can be highlighted on the preset screen. In this way, by controlling the streaming rearview mirror to highlight target reminder information on the preset screen, users can clearly see the displayed target reminder information.
[0146] The operation of determining the target duration for the streaming rearview mirror to rise from the target temperature to the second temperature threshold based on the target temperature can be: determining the target duration from the second correspondence based on the target temperature.
[0147] The second correspondence is between the temperature of the streaming rearview mirror and its temperature recovery time. The temperature recovery time is the time it takes for the streaming rearview mirror to rise from different temperatures to a second temperature threshold. This second correspondence includes multiple temperatures and multiple durations. The multiple temperatures refer to the different temperature environments in which the streaming rearview mirror is located, and the multiple durations refer to the time it takes for the streaming rearview mirror to recover from a corresponding low temperature to the second temperature threshold. Each of the multiple temperatures corresponds one-to-one with a specific duration.
[0148] In this embodiment, the second correspondence can be pre-calibrated. That is, technicians can experimentally control the streaming media rearview mirror to be in different temperature environments, and at different temperatures, perform the operation of step 402 above 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, thereby obtaining the second correspondence.
[0149] For example, Table 2 below shows an example of the second correspondence. Table 2 includes multiple temperatures and multiple durations. The multiple temperatures and multiple durations correspond one-to-one. For instance, the target temperature for the streaming rearview mirror is -25℃, and the target duration can be obtained as 12 minutes from the second correspondence shown in Table 2 below.
[0150] Table 2
[0151] temperature Temperature recovery time -30℃ 15min -2℃ 12min -20℃ 8min …… ……
[0152] The embodiments of this application are merely illustrative examples of the second correspondence described in Table 2 above, and do not constitute a limitation on the embodiments of this application.
[0153] Optionally, the streaming rearview mirror can be controlled to display target reminder information during the display duration.
[0154] The display duration can be preset, and the display duration can be set to a relatively large value.
[0155] In this case, by controlling the streaming rearview mirror to display target reminder information within the display duration, the user can be guaranteed to see the target reminder information.
[0156] In this embodiment of the application, after the streaming media rearview mirror highlights the target reminder information on the preset screen, the following steps (1)-(2) can also be performed during the heating process of the streaming media rearview mirror.
[0157] (1) Detect the temperature of the streaming media rearview mirror as it rises from the target temperature to the second temperature threshold.
[0158] During the process of the streaming rearview mirror rising from the target temperature to the second temperature threshold, the temperature of the streaming rearview mirror can be continuously detected by a temperature sensor to obtain the real-time temperature during the temperature rise process, and to determine whether the temperature of the streaming rearview mirror has returned to the normal temperature.
[0159] Optionally, step (1) can be performed by detecting the temperature of the streaming media rearview mirror every preset time interval during the process of the streaming media rearview mirror rising from the target temperature to the second temperature threshold.
[0160] The preset duration can be set in advance, and the preset duration can be set much shorter than the target duration. For example, if the target duration is 10 minutes, the preset duration can be set to 10 seconds.
[0161] (2) Display the detected temperature of the streaming rearview mirror; and / or, based on the temperature ratio between the detected temperature of the streaming rearview mirror and a second temperature threshold, display a temperature rise progress bar.
[0162] The temperature rise progress bar is used to indicate the rate at which the temperature of the streaming rearview mirror rises.
[0163] In step (2) above, by displaying the detected temperature of the streaming rearview mirror, users can promptly know the real-time temperature of the streaming rearview mirror as it heats up, thereby improving the user experience. Additionally, by displaying a temperature rise progress bar, users can promptly know the temperature rise progress of the streaming rearview mirror, thus improving the user experience.
[0164] Optionally, the detected temperature of the streaming rearview mirror can be displayed via an alarm message or a temperature icon.
[0165] For example, the detected temperature of the streaming rearview mirror can be displayed by flashing at a target frequency, so that users can pay more attention to the real-time temperature of the streaming rearview mirror and obtain the real-time temperature of the streaming rearview mirror more promptly, thereby improving the user experience.
[0166] For example, Figure 5This is a schematic diagram of the display screen of a streaming media rearview mirror provided in an embodiment of this application. See also... Figure 5 , Figure 5 The system includes a streaming rearview mirror 501, which includes a temperature display area 502 and a temperature rise progress bar 503. The temperature display area 502 displays the detected temperature of the streaming rearview mirror. Thus, users can see the current temperature rise progress and the real-time temperature of the streaming rearview mirror by looking at the temperature and temperature rise progress bar displayed on the screen.
[0167] Optionally, a countdown timer can be displayed as the streaming rearview mirror heats up.
[0168] The countdown timer indicates how long it will take for the temperature of the streaming rearview mirror to return to normal, which is the remaining recovery time for the streaming rearview mirror temperature.
[0169] In this scenario, displaying a countdown timer allows users to more intuitively understand how long it will take for the streaming rearview mirror's temperature to rise to normal, thus indicating when the streaming display mode can be used. Furthermore, since users are more concerned with time than temperature, displaying a countdown timer meets their needs, thereby improving the user experience.
[0170] It is worth noting that steps 401 and 402 described above can dissipate heat from the backlight to raise the temperature of the streaming media rearview mirror, thereby restoring the temperature of the streaming media rearview mirror to normal. In this embodiment, after the temperature of the streaming media rearview mirror returns to normal, the streaming media display mode can also be activated.
[0171] Specifically, when the temperature of the streaming rearview mirror rises to a second temperature threshold, the display module is controlled to display the target image; the light transmittance of the dimming glass is adjusted to a second light transmittance and the reflectance of the dimming glass is adjusted to a second reflectance.
[0172] The target image is captured by a camera located behind the vehicle.
[0173] The second transmittance is the maximum transmittance of the dimming glass, and the second reflectance is the minimum reflectance of the dimming glass.
[0174] In this scenario, it's equivalent to controlling the display module to show the image captured by the camera at the rear of the vehicle. Because the reflective glass has the highest reflectivity and lowest transmittance in reflective mirror mode, the image displayed on the display module won't pass through. To make the image displayed on the display module pass through, the reflectivity of the reflective glass can be adjusted to the lowest and the transmittance to the highest; that is, the transmittance of the reflective glass can be adjusted to the second lowest transmittance, and the reflectivity to the second lowest reflectivity.
[0175] It is worth noting that in this embodiment, power can be supplied to the display module, thereby maximizing the light transmittance and minimizing the reflectance of the dimming glass, which is equivalent to enabling the streaming media display mode.
[0176] To facilitate understanding, we will now combine... Figure 6 The method for heating a streaming media rearview mirror provided in the embodiments of this application is illustrated by way of example. Figure 6 A flowchart illustrating another method for heating a streaming media rearview mirror, provided in an embodiment of this application. See also... Figure 6 , Figure 6 This includes the following steps 601-609.
[0177] Step 601: Obtain the target temperature of the streaming 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, proceed to step 603 below; if the target temperature is greater than or equal to the first temperature threshold, continue to maintain the current operating mode.
[0179] Step 603: Control the streaming media rearview mirror to activate the reflector mode.
[0180] Step 604: Increase the power of the backlight and simultaneously control the display module to display the preset image.
[0181] Step 605: Highlight the target reminder information on the preset screen.
[0182] Step 606: During the heating process of the streaming media rearview mirror, detect the temperature of the streaming media rearview mirror.
[0183] Step 607: Determine whether the temperature of the streaming rearview mirror has reached the second temperature threshold. If the temperature of the streaming rearview mirror reaches the second temperature threshold, proceed to step 609 below; if the temperature of the streaming rearview mirror has not reached the second temperature threshold, proceed to step 608 below.
[0184] Step 608: Display the temperature of the streaming rearview mirror and / or display a temperature rise progress bar.
[0185] Step 609: Control the streaming media rearview mirror to start the streaming media display mode.
[0186] In this embodiment, the streaming rearview mirror includes a display module, which includes a backlight. When the streaming rearview mirror controller detects that the mirror is in a preset temperature environment, it can first control the mirror to activate a reflector mode. This reflector mode reflects the environment behind the vehicle using optical reflection principles. That is, even when the streaming rearview mirror exhibits low-temperature ghosting, the user can observe the reflected environment behind the vehicle in reflector mode. Then, the backlight power is increased, and the display module is controlled to display a preset image. Since increasing the backlight power also increases its brightness, the light from the backlight passing through the display module could affect the normal use of the reflector mode. Therefore, while increasing the backlight power, the display module can also be controlled to display a preset image, such as a pure black screen. This allows the streaming rearview mirror to heat up while the backlight heats up, while the preset image blocks the light emitted by the backlight, achieving the goal of heating the mirror through heat dissipation without affecting the user's normal use of the rearview mirror. This solves the problem of motion blur in streaming rearview mirrors under special temperature conditions, thus improving the user experience.
