Abstract
Description
Technical Field
[0001] This application relates to the field of electrochromic technology, and more particularly to an anti-glare rearview mirror control method, device, vehicle, and readable storage medium. Background Technology
[0002] One of the problems that needs to be solved for electrochromic anti-glare rearview mirrors is that the electrochromic device changes color slowly at low temperatures, thus requiring a solution to accelerate the color change. Current solutions typically involve heating the electrochromic device to increase its temperature and thus increase the color-changing speed. However, existing solutions often employ a heating control method that activates the heating element to continuously heat the rearview mirror when the ambient temperature is detected to be below a certain threshold or when rain or snow is detected. Summary of the Invention
[0003] In view of this, this application provides an anti-glare rearview mirror control method, device, vehicle, and readable storage medium.
[0004] In a first aspect, embodiments of this application provide an anti-glare rearview mirror control method, including:
[0005] When it is nighttime and the current temperature is below the preset minimum temperature, check whether the anti-glare pre-start conditions are met;
[0006] When the anti-glare pre-start conditions are met, the heating operation of the rearview mirror is initiated until it is heated to the target temperature under the current environment.
[0007] In some embodiments, the anti-glare pre-activation condition is determined to be met when any of the following conditions are detected:
[0008] When the difference in light intensity between the front light intensity in the direction of the vehicle's front and the rear light intensity in the direction of the vehicle's rear is greater than or equal to the first preset light intensity difference value;
[0009] When a signal is received indicating that a vehicle exists in the blind spot.
[0010] In some embodiments, the anti-glare rearview mirror control method further includes:
[0011] During the heating operation, the light intensity difference between the front light intensity in the direction of the vehicle's front and the rear light intensity in the direction of the vehicle's rear is continuously acquired.
[0012] If the updated light intensity difference value is greater than or equal to the second preset light intensity difference value, then the color-changing operation of the rearview mirror is activated, where the second preset light intensity difference value is greater than the first preset light intensity difference value.
[0013] In some embodiments, the anti-glare rearview mirror control method further includes:
[0014] During the heating operation, the presence of a vehicle in the blind spot is continuously monitored.
[0015] When no vehicle is detected in the blind spot, the current heating operation is stopped or the current heating temperature is maintained.
[0016] In some embodiments, the anti-glare rearview mirror control method further includes:
[0017] If the updated light intensity difference value is less than the first preset light intensity difference value, or if the rearview mirror has completed the color-changing operation, then the heating operation of the rearview mirror is stopped or maintained at the current heating temperature.
[0018] In some embodiments, the target temperature is obtained based on a preset relationship between the target temperature and the ambient temperature, the preset relationship being as follows:
[0019] When the ambient temperature is within the first preset temperature range, the target temperature is set to the first temperature value;
[0020] When the ambient temperature is within the second preset temperature range, the target temperature and the ambient temperature satisfy a preset function, and the temperature in the first preset temperature range is not greater than the temperature in the second preset temperature range.
[0021] In some embodiments, the light intensity difference value is the light intensity ratio between the front light intensity and the rear light intensity, the light intensity difference between the front light intensity and the rear light intensity, or the light intensity ratio between the front light intensity and the rear light intensity.
[0022] In some embodiments, the rearview mirror is provided with different heating levels, including a first power level and a second power level, wherein the second power level is higher than the first power level;
[0023] When the anti-glare pre-start conditions are met, select the second power setting to heat the rearview mirror.
[0024] When the temperature maintenance operation is met, switch to the first power setting to heat the rearview mirror.
[0025] Secondly, embodiments of this application provide an anti-glare rearview mirror control device, comprising:
[0026] The detection module is used to detect whether the anti-glare pre-start conditions are met when it is nighttime and the current temperature is lower than the preset minimum temperature.
[0027] The heating control module is used to initiate the heating operation of the rearview mirror when the anti-glare pre-start conditions are met, until it is heated to the target temperature in the current environment.
[0028] Thirdly, embodiments of this application provide a vehicle, the vehicle including an anti-glare rearview mirror, a processor and a memory, the memory storing a computer program, and the processor executing the computer program to implement the above-described anti-glare rearview mirror control method.
[0029] Fourthly, embodiments of this application provide a readable storage medium storing a computer program, which, when executed on a processor, implements the aforementioned anti-glare rearview mirror control method.
[0030] The embodiments of this application have the following beneficial effects:
[0031] The anti-glare rearview mirror control method of this application detects whether the anti-glare pre-activation condition is met when it is nighttime and the current temperature is below a preset minimum temperature. If the anti-glare pre-activation condition is met, the heating operation of the rearview mirror is initiated until it is heated to the target temperature of the current environment. By determining that glare is about to occur and preheating the rearview mirror in advance, it can quickly change color when needed. In addition, compared with the traditional method of continuous heating, it can save energy, and since the rearview mirror does not need to be in a high-temperature heating state for a long time, it extends the service life of the anti-glare rearview mirror.

[0044] Example 1
[0045] Figure 1 The diagram shown is a first flowchart of an anti-glare rearview mirror control method according to an embodiment of this application. Exemplarily, the anti-glare rearview mirror control method includes:
[0046] Step S110: When it is nighttime and the current temperature is lower than the preset minimum temperature, check whether the anti-glare pre-start conditions are met.
[0047] In this embodiment, the anti-glare rearview mirror mainly includes a lens with an electrochromic structure, a heating element, a temperature sensor, a front light intensity sensor facing the front of the vehicle, and a rear light intensity sensor facing the rear of the vehicle. The electrochromic structure enables the anti-glare function of the rearview mirror, the heating element heats the lens, and the front and rear light intensity sensors acquire the light intensity in their respective directions. Determining whether the vehicle is currently in nighttime can be achieved by using a separate ambient light sensor or by using an existing front light intensity sensor. For example, if the ambient light intensity is detected to be below a certain value, it can be considered that the vehicle is in nighttime. Alternatively, it can be determined by local time, network connectivity, or the user directly selecting a nighttime period. One or more temperature sensors can be used to collect the temperature of the rearview mirror and the ambient temperature. The ambient temperature can be obtained through a separate temperature sensor or by using network communication or other methods to obtain the local temperature. In addition, in some cases, such as when the vehicle has not been heated for a long time or when the vehicle has just been started, the ambient temperature can be taken as the temperature of the rearview mirror when the vehicle is started, or the average of several lowest temperature points in the curve of the rearview mirror can be taken as the ambient temperature, etc., without limitation.
[0048] When a vehicle is in a cold night, if the temperature is too low, the anti-glare rearview mirror may change color slowly, making it difficult to achieve the anti-glare effect in time, which may pose a driving risk to the driver. Therefore, heating is required. However, in this embodiment, in addition to meeting the low temperature requirement, the anti-glare pre-activation condition must be detected before the preheating of the rearview mirror is activated, thereby achieving the purpose of energy saving.
[0049] The current temperature can be the temperature of the rearview mirror or the ambient temperature. For example, the preset minimum temperature can be around -10℃, but it can be adjusted according to actual needs.
[0050] The aforementioned anti-glare pre-activation conditions refer to the activation conditions for the preheating operation before activating the anti-glare system. In this embodiment, the degree of light intensity difference between the front and rear of the vehicle can be used to determine whether glare is about to occur. It can be understood that when a vehicle approaches from behind, if the following vehicle has its headlights on, the rear light intensity sensor of this vehicle will detect that the rear light intensity in the direction of the rear of the vehicle is becoming increasingly stronger, meaning the light intensity difference between the front and rear of this vehicle will gradually increase. Therefore, two light intensity difference values of different magnitudes can be set here. The first preset light intensity difference value is smaller than the second preset light intensity difference value. When the first preset light intensity difference value is reached, it indicates that glare may occur in a short time, and the rearview mirror will be preheated to ensure that the rearview mirror can quickly change color when needed. When the second preset light intensity difference value is reached, it indicates that the conditions for glare to occur are met, and a color-changing operation is required to prevent glare.
[0051] In another scenario, if a vehicle approaching from the side or rear is in the blind spot, it may accelerate or the vehicle from the side or rear may decelerate or change lanes, causing the vehicle to leave the blind spot and enter the rearview mirror's field of vision, quickly causing glare in the rearview mirror. If, in this situation, glare is still predicted and preheated solely based on the aforementioned light intensity difference, the anti-glare rearview mirror may not have enough time to preheat. To address this, this embodiment can also use a blind spot detector (BSD) to detect whether there is a vehicle in the blind spot. When there is a vehicle in the blind spot, the blind spot detector can send a signal indicating the presence of a vehicle in the blind spot, at which point the rearview mirror will be preheated to ensure that the rearview mirror can quickly change color when needed.
[0052] In one implementation, if any of the following conditions are detected, it can be determined that the above-mentioned anti-glare pre-activation conditions are met, which may include, but are not limited to: when the difference in light intensity between the front light intensity in the direction of the vehicle's front and the rear light intensity in the direction of the vehicle's rear is greater than or equal to a first preset light intensity difference value; or, when a signal indicating the presence of a vehicle in the blind spot is received, etc.
[0053] For example, the aforementioned light intensity difference value can be the ratio of the front light intensity to the rear light intensity in the direction of the vehicle's front. Of course, it can also be other parameters that can represent the degree of difference in front and rear light intensity, such as the light intensity difference between the front and rear light intensities, or the logarithmic ratio of the front and rear light intensities, etc., without limitation. It can be understood that the preset light intensity difference value in this embodiment can be selected according to the actual light intensity difference value. Furthermore, to improve the accuracy of judgment, the light intensity difference value in this embodiment can be determined by comparing multiple consecutively collected data points multiple times, and the final light intensity difference value can be determined based on the results of these multiple comparisons. This can reduce the probability of misjudgment.
[0054] In this embodiment, under the premise of low temperature at night, the system determines whether glare is about to occur by the difference in light intensity between the front and rear and by detecting vehicles in the blind spot. When glare is determined to be about to occur, the rearview mirror is preheated in advance so that it can quickly change color when needed.
[0055] Step S120: When the anti-glare pre-start conditions are met, start the heating operation on the rearview mirror until it is heated to the target temperature in the current environment.
[0056] The target temperature mentioned above refers to the temperature point that facilitates the rapid color change of the rearview mirror. It is worth noting that the target temperature in this embodiment may not be a constant value; it may also be related to the ambient temperature. Specifically, it can be determined in real time based on a preset relationship between the target temperature and the ambient temperature.
[0057] Regarding the target temperature mentioned above, all possible ambient temperature values are divided into multiple temperature ranges. The method for determining the target temperature differs depending on the ambient temperature range. For example, in one implementation, it can be divided into three ranges: a first to a third preset temperature range. The temperatures in the first, second, and third preset temperature ranges increase sequentially, meaning the temperature in the second preset temperature range is not lower than the temperature in the first preset temperature range, and the temperature in the third preset temperature range is not lower than the temperature in the second preset temperature range. For example, in one implementation, the maximum value of the second preset temperature range can be set to the aforementioned preset minimum temperature. It can be understood that the first preset temperature range is a non-color-changing temperature range, the second preset temperature range is a transitional temperature range, and the third preset temperature range is a suitable color-changing temperature range. If the mirror is in this suitable color-changing temperature range, preheating is not required. Furthermore, two or four temperature ranges can also be used, and the specific range can be adjusted adaptively according to actual needs.
[0058] Based on the above three interval divisions, the preset relationship between two temperatures can be described, for example, as follows:
[0059] When the ambient temperature is within a first preset temperature range, the target temperature is set to a first temperature value; when the ambient temperature is within a second preset temperature range, the target temperature and the ambient temperature satisfy a preset function. For example, taking the division of the first preset temperature range as less than -40℃, the second preset temperature range as -40℃ to 0℃, and the third preset temperature range as greater than 0℃ as an example, in one preset relationship, such as... Figure 2aAs shown, the first temperature value can be set to a fixed value, which can be selected according to actual needs. Optionally, its range can be -16℃ to -20℃, etc. In this case, the second preset temperature range includes two sub-ranges: the first sub-range [-40℃ to -20℃) and the second sub-range [-20℃ to 0℃). Correspondingly, the expression of the preset function, which is a piecewise function, is different in each sub-range. The target temperature in the first sub-range can be set to a fixed value, and its range can refer to the selection of the first temperature value in the first preset temperature range, with a slope of 0. In the second sub-range, the target temperature has a linear relationship with the ambient temperature, and the slope is 1. In the third preset temperature range, since it is suitable for the color-changing temperature range, for example, the target temperature can be set to the ambient temperature. This way, if the vehicle is currently in the current temperature range, the preheating operation of the anti-glare rearview mirror will not be triggered.
[0060] Alternatively, it can also be set as follows Figure 2b The second type of preset relationship shown, or as... Figure 2c The third preset relationship is shown above. The main difference between these preset relationships lies in the different sub-interval divisions of the second preset temperature range, and correspondingly, the expressions of the preset functions are also different.
[0061] Specifically, in the second preset relationship, the second preset temperature range is also divided into two sub-ranges: the first sub-range [-40℃~-30℃) and the second sub-range [-30℃~0℃). Within the sub-range [-40℃~-30℃), the target temperature can be set to a fixed value, such as -20℃. In the sub-range [-30℃~0℃), the target temperature is positively correlated with the ambient temperature, and the slope of the tangent line is no greater than 1. In the third preset relationship, the second preset temperature range includes only one range [-20℃~0℃). In this case, the preset function is a linear function with a slope less than 1 that does not pass through the origin.
[0062] It is understood that the above-mentioned target temperature and ambient temperature relationship curves are only examples and not the only limitations. In this embodiment, energy can be saved by setting different heating strategies in different ambient temperature ranges. For example, when in the suitable color-changing temperature range, the target temperature is set to the ambient temperature, so that no heating is required; when in the non-color-changing temperature range, the target temperature can be set to the transition temperature point, so that more heating is required to ensure performance; and when in the transition temperature range, the target temperature can be set to increase with the increase of the ambient temperature, so that less heating is required compared to the non-color-changing temperature range, etc.
[0063] As an example, if any of the above-mentioned anti-glare pre-activation conditions are detected, it indicates that rearview mirror glare may occur subsequently. Therefore, this embodiment will initiate a preheating operation on the rearview mirror until it reaches the target temperature corresponding to the current ambient temperature, to ensure that the rearview mirror can quickly respond with a color change when anti-glare activation is required. Further optionally, after heating to the target temperature, heating can be stopped according to actual needs, or the temperature can be maintained at around the target temperature (i.e., heat preservation operation), etc.
[0064] Optionally, the heating element of the rearview mirror in this embodiment may have different heating levels, including a first power level and a second power level, and the heating power of the second power level will be higher than that of the first power level. For example, when the anti-glare pre-start conditions are met or the anti-glare function is activated, the second power level can be selected to perform a strong heating operation on the rearview mirror; conversely, when the conditions for temperature maintenance are met, the first power level can be switched to heat the rearview mirror.
[0065] Alternatively, only one heating power level can be set. Specifically, when the rearview mirror needs heating, it can be heated. When the target temperature is reached or a temperature maintenance operation is required, heating can be intermittently activated to keep the temperature near the current or target temperature. It can be understood that for heating elements with different heating levels, intermittent heating can also be used to keep the rearview mirror near the current or target temperature.
[0066] Furthermore, such as Figure 3 As shown, the anti-glare rearview mirror control method also includes:
[0067] Step S130: During the heating operation, continuously acquire the light intensity difference value between the front light intensity in the direction of the vehicle's front and the rear light intensity in the direction of the vehicle's rear.
[0068] Step S140: Detect whether the real-time updated light intensity difference value is greater than or equal to the second preset light intensity difference value. It can be understood that the second preset light intensity difference value is greater than the aforementioned first preset light intensity difference value.
[0069] As an example, during the heating process, the rearview mirror continuously collects light intensity difference values, and immediately executes the anti-glare function when it detects that the updated light intensity difference value is greater than or equal to the second preset light intensity difference value.
[0070] Step S150: If the difference in light intensity is greater than or equal to the second preset light intensity difference value, then the color change operation is started.
[0071] As an example, the light transmittance of the electrochromic structure in the rearview mirror can be adjusted by applying pressure to the electrochromic structure. By darkening the rearview mirror, the intensity of reflected light from vehicles approaching from behind can be reduced, thus avoiding excessive glare and ensuring driving safety.
[0072] For example, in one scenario, at night when the temperature is low, a vehicle gradually approaches from behind and continues to follow, causing the front-to-rear light intensity ratio of the vehicle to gradually increase and then remain at a high value. When the rearview mirror detects that the front-to-rear light intensity ratio is higher than a first preset value, it will activate the preheating of the rearview mirror until it reaches the target temperature and maintains that temperature. Then, when the front-to-rear light intensity ratio rises to the second preset value that triggers the anti-glare rearview mirror to change color, the rearview mirror will start to change color. After the color change is complete, the rearview mirror has an anti-glare effect. Since the transmittance of the anti-glare rearview mirror is lower than the preset transmittance, there is no need for the vehicle to continue heating. Therefore, the heating power can be reduced, or heating can be intermittent, or heating can be stopped directly.
[0073] As an optional solution, if it is detected that the rearview mirror has completed the color-changing operation, that is, the current transmittance of the rearview mirror is lower than the preset transmittance, considering that the transmittance of the rearview mirror may need to be further adjusted to achieve the fading operation, etc., in order to quickly respond to the subsequent adjustment operation, the rearview mirror is maintained at the current heating temperature after the color change.
[0074] Optionally, in step S140 above, if the continuously updated light intensity difference value is detected to be less than the second preset light intensity difference value but still greater than the first preset light intensity difference value, detection can continue, and heating can be maintained near the current temperature or the target temperature. No further operation is required in this case. Further, if the continuously updated light intensity difference value is detected to be less than the first preset light intensity difference value again, it indicates that glare will not occur in the short term, and step S160 is executed.
[0075] In step S160, if the difference in light intensity is less than the first preset value, the heating operation of the rearview mirror is stopped or maintained at the current heating temperature.
[0076] For example, if it is detected that glare will not occur in the short term, the heating operation can be stopped directly, or the temperature reached during the current heating can be maintained. For example, the current heating temperature can be the temperature before the target temperature is reached, or the temperature near the target temperature.
[0077] Furthermore, such as Figure 4 As shown, the anti-glare rearview mirror control method also includes:
[0078] Step S170: During the heating operation, continuously detect whether there are vehicles in the blind spot.
[0079] In step S180, when no vehicle is detected in the blind spot, the current heating operation is stopped or the current heating temperature is maintained.
[0080] As an example, when no vehicle is detected in the blind spot, it indicates that there is no vehicle in the blind spot that may be about to enter the rearview mirror's field of vision, and glare will not occur temporarily. Therefore, the heating operation can be stopped or maintained at the current heating temperature, etc.
[0081] As an alternative solution, the heating function for anti-glare in this embodiment can also be combined with weather conditions such as rain, snow, and freezing rain. For example, when it rains, activating the heating of the anti-glare rearview mirror puts it at the temperature of the rain-removal mode, allowing rainwater to evaporate quickly and preventing raindrops from adhering to the mirror surface and causing poor visibility. Similarly, snowflakes easily adhere to the rearview mirror during snowfall, and freezing rain easily forms an ice layer on the mirror surface, all of which affect the clarity of the rearview mirror. Therefore, in these situations, the rearview mirror can be heated to maintain a snow- and freeze-proof temperature, thus simultaneously achieving anti-glare, rain / snow / freezing rain protection effects.
[0082] The anti-glare rearview mirror control method of this embodiment requires almost no change to the existing structure and materials of the rearview mirror. In low-temperature conditions at night, it determines whether glare is about to occur by detecting the difference in light intensity between the front and rear of the vehicle and by using blind spot vehicle detection. When glare is determined to occur, the rearview mirror is preheated in advance. On the one hand, it can quickly change color when needed. On the other hand, compared with the traditional method of continuous heating, it can save energy. Furthermore, since the rearview mirror does not need to be in a high-temperature heating state for a long time, the service life of the anti-glare rearview mirror is extended.

[0090] The heating control module 120 is used to stop the heating operation of the rearview mirror or maintain the current heating temperature if the updated light intensity difference value is less than the first preset light intensity difference value, or if the rearview mirror has completed the color-changing operation.
