[0002] When a vehicle is traveling in a dark environment, if a vehicle comes from behind, the headlights of the vehicle behind will shine on the interior and exterior rearview mirrors of the vehicle, causing the driver to be dazzled. After being dazzled, the driver will not be able to see the road ahead clearly, thus causing a safety accident.

[0003] To avoid the driver being dazzled in the above situation, some vehicles currently are equipped with anti-glare rearview mirrors. In this way, when the lights of the vehicle behind shine on the rearview mirror, the driver can manually trigger the anti-glare function of the electrochromic (EC) anti-glare rearview mirror.

[0044] In order to be able to more clearly understand the above-mentioned objects, features and advantages of the present disclosure, the following will further describe the solutions of the present disclosure. It should be noted that, without conflict, the embodiments of the present disclosure and the features in the embodiments can be combined with each other.

[0045] In the following description, many specific details are set forth in order to fully understand the present disclosure, but the present disclosure can also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only a part of the embodiments of the present disclosure, rather than all the embodiments.

[0046] With the continuous development of vehicle technology, when a vehicle is driving in a dark environment, if the headlights of a vehicle behind shine on the interior and exterior rearview mirrors, it will cause glare to the driver, thus leading to safety accidents. In the prior art, when the vehicle behind shines on the rearview mirror, the driver can manually control the electrochromic (EC) anti-glare rearview mirror to trigger the anti-glare function. However, in this way, the driver needs to be distracted to perform manual operations during driving, which is not conducive to driving safety.

[0047] To solve the problems of the prior art, the embodiments of the present application provide a method, device, equipment, medium and vehicle for adjusting the anti-glare of a vehicle rearview mirror. First, the method for adjusting the anti-glare of a vehicle rearview mirror provided by the embodiments of the present application will be introduced below.

[0048] Figure 1 The flowchart of the method for adjusting the anti-glare of a vehicle rearview mirror provided by an embodiment of the present application is shown. As Figure 1 shown, a method for adjusting the anti-glare of a vehicle rearview mirror may include the following steps S101 to S103:

[0049] S101. Obtain the current ambient illumination value collected by the front sensor of the vehicle, and obtain the current rear illumination value collected by the rear sensor of the vehicle. The front sensor is located at the front of the vehicle, and the rear sensor is located at the rear of the vehicle. The ambient illumination value is the illumination value of the light source in the environment where the vehicle is located, and the rear illumination value is the illumination value of the light of the vehicle coming from behind.

[0050] S102. Determine the target anti-glare level corresponding to the ambient illumination value and the rear illumination value among multiple preset anti-glare levels of the rearview mirror, where different anti-glare levels among the multiple anti-glare levels have different anti-glare effects.

[0051] S103. Adjust the anti-glare level of the rearview mirror to the target anti-glare level.

[0052] The anti-glare adjustment method for a vehicle rearview mirror according to an embodiment of the present application can obtain the current ambient light intensity value collected by a front sensor of the vehicle and, at the same time, obtain the current rear light intensity value collected by a rear sensor of the vehicle. The ambient light intensity value is the light intensity value of the light source in the environment where the vehicle is located, and the rear light intensity value is the light intensity value of the lights of the oncoming vehicle behind the vehicle; among multiple preset anti-glare levels of the rearview mirror, determine the target anti-glare level corresponding to the ambient light intensity value and the rear light intensity value. Among them, different anti-glare levels among the multiple anti-glare levels have different anti-glare effects; adjust the anti-glare level of the rearview mirror to the target anti-glare level. In this way, according to the ambient light intensity value and the rear light intensity value of the vehicle, the embodiment of the present application can determine the target anti-glare level and automatically adjust the anti-glare level of the rearview mirror to the target anti-glare level to reduce the dazzling impact of the lights of the oncoming vehicle behind on the driver, without manual operation by the driver, thereby improving driving safety. Moreover, by combining the ambient light intensity value and the rear light intensity value of the vehicle, the accuracy of the target anti-glare level is higher, so that a suitable visual experience can be provided for the user.

[0053] The specific implementation methods of the above steps are introduced below.

[0054] In S101, the above ambient light intensity value can be the light intensity value of the environment where the vehicle is located. The acquisition of the above ambient light intensity value, exemplarily, can be directly collected by a front sensor, or the ambient light intensity value can also be calculated by calculating the current scattered light intensity value and the preset direction light intensity value collected by the front sensor. The scattered light intensity value is the light intensity value of the scattered light in the environment where the vehicle is located, and the preset direction light intensity value is the light intensity value of the light in the preset direction angle of the vehicle. Among them, the preset direction is the direction set by the existing front sensor at the factory. In the present application, it is not limited to a certain fixed direction and can be set according to the actual needs of the user, and no specific limitation is made here.

[0055] The above rear light intensity value can be the light intensity value of the lights of the oncoming vehicle behind the vehicle without obstruction.

[0056] The installation positions of the above front sensor and rear sensor are different. One advantage of such a setting is that the ambient light collected by the front sensor is less affected by the lights of the oncoming vehicle behind, and the intensity of the rear lights collected by the rear sensor is more accurate. For example, the front sensor can include at least one of a front windshield sensor and a rearview mirror sensor. Among them, the front windshield sensor is located in the front windshield area of the vehicle, and the rearview mirror sensor is located in the area of the vehicle's interior rearview mirror facing the front of the vehicle. To avoid the influence of item occlusion on the acquisition of the rear light intensity value, the rear sensor can be a sensor located in areas such as the vehicle's tail or the rear windshield. To further facilitate the vehicle to observe the situation of the oncoming vehicle behind, the rear sensor can also be a streaming media camera capable of collecting the light intensity value.

[0057] In S102, among the multiple preset anti-glare levels, different anti-glare levels have different anti-glare effects. Exemplarily, there are 10 levels of multiple anti-glare levels, starting from 0 - 9, and the anti-glare effect gets better gradually. That is, the 0 anti-glare level can be no anti-glare effect, and the 9 anti-glare level can be the best anti-glare effect.

[0058] Among the multiple anti-glare levels of the rearview mirror, determine the target anti-glare level corresponding to the ambient light intensity value and the rear light intensity value. Exemplarily, it can be to determine the target anti-glare level corresponding to both the ambient light intensity value and the rear light intensity value among the multiple anti-glare levels of the rearview mirror. Or, it can also be to determine the target driving scenario corresponding to the ambient light intensity value in multiple driving scenarios. Different driving scenarios are associated with different multiple anti-glare levels of the rearview mirror; among the multiple anti-glare levels associated with the target driving scenario, determine the target anti-glare level corresponding to the rear light intensity value.

[0059] In S103, the above-mentioned rearview mirror can be the left exterior rearview mirror of the vehicle. Of course, it is not limited to this, and it can also be all rearview mirrors. The specific situation can be set according to user needs.

[0060] Adjust the anti-glare level of the rearview mirror to the target anti-glare level. Exemplarily, it can be to adjust the rearview mirror from the initial 0 anti-glare level or the default 3 anti-glare level to the target anti-glare level. Or, it can also be to follow the real-time ambient light intensity value and rear light intensity value, and adjust the rearview mirror from the anti-glare level of the previous moment to the target anti-glare level.

[0061] In some embodiments, the above-mentioned front sensor can include at least one of a front windshield sensor and a rearview mirror sensor. The front windshield sensor is located in the front windshield area at the front of the vehicle, and the rearview mirror sensor is located in the forward-facing area of the interior rearview mirror of the vehicle;

[0062] The rear sensor is a streaming camera capable of collecting the light intensity value, and is used to collect the rear light intensity value without occlusion.

[0063] The above-mentioned front windshield sensor, exemplarily, the front windshield sensor can be a rain and light sensor.

[0064] The above-mentioned rearview mirror sensor is located in the forward-facing area of the interior rearview mirror of the vehicle. Exemplarily, it can be the front light sensor of the streaming interior rearview mirror.

[0065] In this embodiment, the front windshield sensor is located in the front windshield area of the vehicle, so that the collected ambient light intensity value can be closer to the real external environment. The rearview mirror sensor is located in the area facing the front of the vehicle's interior rearview mirror, so that the collected ambient light intensity value can be more stable. Therefore, the ambient light intensity value can be accurately collected through at least one of the front windshield sensor and the rearview mirror sensor.

[0066] In some embodiments, when the above-mentioned front sensor is the front windshield sensor, S101 may specifically include:

[0067] Obtain the ambient light intensity value collected by the front windshield sensor at present, and obtain the rear light intensity value collected by the rear sensor of the vehicle at present;

[0068] The above-mentioned S102 may specifically include:

[0069] Among multiple preset anti-glare levels of the rearview mirror, determine the target anti-glare level corresponding to the ambient light intensity value and the rear light intensity value.

[0070] When the front windshield sensor is a rain and light sensor, among multiple preset anti-glare levels of the rearview mirror, determining the target anti-glare level corresponding to the ambient light intensity value and the rear light intensity value. Exemplarily, when the ambient light intensity value is less than 90 and the rear light intensity value is greater than or equal to 5500, determine that the target anti-glare level is 5; it can also be when the ambient light intensity value is greater than or equal to 90 and less than 1200, and the rear light intensity value is greater than or equal to 5500, determine that the target anti-glare level is 3.

[0071] In this embodiment, by collecting the ambient light intensity value at present through the front windshield sensor and collecting the rear light intensity value at present through the rear sensor, the target anti-glare level corresponding to the ambient light intensity value and the rear light intensity value can be determined among multiple preset anti-glare levels of the rearview mirror.

[0072] In some embodiments, when the above-mentioned front sensor includes the front windshield sensor and the rearview mirror sensor, S101 may specifically include:

[0073] Obtain the first ambient light intensity value collected by the front windshield sensor at present, and obtain the second ambient light intensity value collected by the rearview mirror sensor at present,

[0074] wherein, the ambient light intensity value includes the first ambient light intensity value and the second ambient light intensity value. The accuracy of the first ambient light intensity value is higher than that of the second ambient light intensity value, and the stability of the second ambient light intensity value is higher than that of the first ambient light intensity value.

[0075] The above-mentioned acquisition of the current first ambient light intensity value collected by the front windshield sensor may be directly obtaining the current first ambient light intensity value collected by the front windshield sensor, or alternatively, it may also be obtaining the current scattered light intensity value and the preset direction light intensity value collected by the front windshield sensor. The scattered light intensity value is the light intensity value of the scattered light in the environment where the vehicle is located, and the preset direction light intensity value is the light intensity value of the light in the preset direction angle of the vehicle. Calculate the scattered light intensity value and the preset direction light intensity value to obtain the first ambient light intensity value. Among them, the preset direction is the direction set by the existing front sensor at the factory. In this application, it is not limited to a certain fixed direction and can be set according to the actual needs of the user, and no specific limitation is made here.

[0076] In this embodiment, the front windshield sensor collects the first ambient light intensity value that is close to the real external environment at that time, and the rearview mirror sensor collects the second ambient light intensity value that is more stable at that time. These two characteristic ambient light intensity values can help select the target anti-glare level that conforms to the environment where the vehicle is located when determining the target anti-glare level.

[0077] In some embodiments, the above S102 may specifically include:

[0078] Judge whether the first ambient light intensity value is less than a preset first threshold;

[0079] When the first ambient light intensity value is less than the first threshold, determine the target anti-glare level corresponding to the ambient light intensity value and the rear light intensity value among the multiple preset anti-glare levels of the rearview mirror.

[0080] The above-mentioned preset first threshold can be used to judge whether the environment where the vehicle is located is a bright environment (such as during the day) or a dark environment (such as at night). Exemplarily, it can be 1200 lux. In this application, it is not limited to this and can also be other values, and no specific limitation is made here.

[0081] When the first ambient light intensity value is less than the first threshold, among the multiple preset anti-glare levels of the rearview mirror, determining the target anti-glare level corresponding to the ambient light intensity value and the rear light intensity value may be, when the first ambient light intensity value is less than the first threshold, determining whether the rear light intensity value is greater than a preset second threshold; when the rear light intensity value is greater than the second threshold, among the multiple preset anti-glare levels of the rearview mirror, determining the target anti-glare level corresponding to the first ambient light intensity value. Or, when the first ambient light intensity value is less than the first threshold, determining the target second ambient light intensity value range in which the second ambient light intensity value is located from multiple preset second ambient light intensity value ranges; the preset rear light intensity value ranges corresponding to the same anti-glare level are different under different preset second ambient light intensity value ranges; determining the target rear light intensity value range corresponding to the rear light intensity value under the target second ambient light intensity value range, and determining the anti-glare level corresponding to the target rear light intensity value range as the target anti-glare level. It may also be that when the first ambient light intensity value is less than the first threshold, determining whether the first ambient light intensity value is less than a preset third threshold, and the third threshold is less than the first threshold; when the first ambient light intensity value is less than the third threshold, determining whether the second ambient light intensity value is less than a preset fourth threshold; when the second ambient light intensity value is less than the fourth threshold, among the multiple preset anti-glare levels of the rearview mirror, determining the target anti-glare level corresponding to the rear light intensity value.

[0082] When the above first ambient light intensity value is greater than or equal to the first threshold, the EC anti-glare is not performed.

[0083] In the embodiments of the present application, by determining whether the first ambient light intensity value is less than the preset first threshold, it is possible to accurately identify whether the vehicle is in a dark environment, and determine that the vehicle is in a dark environment before determining the target anti-glare level corresponding to the ambient light intensity value and the rear light intensity value from the multiple anti-glare levels of the rearview mirror, which can help the user adjust the anti-glare of the vehicle rearview mirror in a suitable environment.

[0084] In some embodiments, when the first ambient light intensity value is less than the first threshold, among the multiple preset anti-glare levels of the rearview mirror, determining the target anti-glare level corresponding to the ambient light intensity value and the rear light intensity value may specifically include:

[0085] When the first ambient light intensity value is less than the first threshold, determining whether the rear light intensity value is greater than a preset second threshold;

[0086] When the rear light intensity value is greater than the second threshold, among the multiple preset anti-glare levels of the rearview mirror, determining the target anti-glare level corresponding to the first ambient light intensity value.

[0087] The above-mentioned preset second threshold, by way of example, may be 5500 lux. In the present application, it is not limited thereto and may also be other values, which are not specifically limited herein.

[0088] Among the multiple preset anti-glare levels of the rearview mirror, determining the target anti-glare level corresponding to the first ambient illumination value. By way of example, when the first ambient illumination value is less than 90, it means that the vehicle is in an environment with strong light in the basement and weak light, and the target anti-glare level is determined to be the 5th gear; when the first ambient illumination value is greater than or equal to 90, it means that the vehicle is in an environment with strong light in the basement and strong light, and the target anti-glare level is determined to be the 3rd gear.

[0089] In this embodiment, when the first ambient illumination value is less than the first threshold and the rear illumination value is greater than the second threshold, the target anti-glare level corresponding to the first ambient illumination value can be accurately determined among the multiple preset anti-glare levels of the rearview mirror.

[0090] In some embodiments, when the first ambient illumination value is less than the first threshold, determining the target anti-glare level corresponding to the ambient illumination value and the rear illumination value among the multiple preset anti-glare levels of the rearview mirror may specifically include:

[0091] When the first ambient illumination value is less than the first threshold, determining the target second ambient illumination value range in which the second ambient illumination value is located from multiple preset second ambient illumination value ranges; the preset rear illumination value ranges corresponding to the same anti-glare level are different under different preset second ambient illumination value ranges;

[0092] Determining the target rear illumination value range corresponding to the rear illumination value under the target second ambient illumination value range, and determining the anti-glare level corresponding to the target rear illumination value range as the target anti-glare level.

[0093] The preset rear illumination value ranges corresponding to the same anti-glare level are different under different preset second ambient illumination value ranges. By way of example, when the second ambient illumination value is less than or equal to 0.1, the preset rear illumination value ranges of multiple anti-glare levels may be: above 4500: EC function 9th gear; 4400 - 4500: EC function 4th gear; not entering EC below 4400. When the second ambient illumination value is greater than 0.1 and less than or equal to 2.5, the preset rear illumination value ranges of multiple anti-glare levels may be: above 4500: EC function 5 - 9th gear; 4400 - 4500: 4th gear. When the second ambient illumination value is greater than 2.5, the preset rear illumination value ranges of multiple anti-glare levels may be: above 4700: EC function 1 - 5th gear; not entering EC below 4700.

[0094] When the first ambient light intensity value is less than the first threshold, if the second ambient light intensity value is less than or equal to 0.1, it means the environment of extremely dark night or weak light basement during the day; if the second ambient light intensity value is greater than 0.1 and less than or equal to 2.5, it means the environment of weak street lights at night or weak light basement during the day; if the second ambient light intensity value is greater than 2.5, it means the environment of strong street lights at night or weak light basement during the day.

[0095] In this embodiment, considering that the preset rear light intensity value ranges corresponding to the same anti-glare level are different under different preset second ambient light intensity value ranges, therefore, when the first ambient light intensity value is less than the first threshold, the target second ambient light intensity value range in which the second ambient light intensity value is located can be determined from multiple preset second ambient light intensity value ranges to provide a more realistic anti-glare effect for the driver.

[0096] In some embodiments, when the first ambient light intensity value is less than the first threshold, determining the target anti-glare level corresponding to the ambient light intensity value and the rear light intensity value among multiple preset anti-glare levels of the rearview mirror may specifically include:

[0097] When the first ambient light intensity value is less than the first threshold, determine whether the first ambient light intensity value is less than a preset third threshold, and the third threshold is less than the first threshold;

[0098] When the first ambient light intensity value is less than the third threshold, determine whether the second ambient light intensity value is less than a preset fourth threshold;

[0099] When the second ambient light intensity value is less than the fourth threshold, determine the target anti-glare level corresponding to the rear light intensity value among multiple preset anti-glare levels of the rearview mirror.

[0100] The above-mentioned preset third threshold is less than the first threshold and can be used to determine that the environment where the vehicle is located is an extremely dark environment. Exemplarily, it can be 90 lux (Lux). In this application, it is not limited to this, and it can also be other values, which are not specifically limited here.

[0101] The above-mentioned preset fourth threshold, exemplarily, can be 0.1 lux (Lux). In this application, it is not limited to this, and it can also be other values, which are not specifically limited here.

[0102] When the second ambient illumination value is less than the fourth threshold, among the multiple preset anti-glare levels of the rearview mirror, determine the target anti-glare level corresponding to the rear illumination value. Exemplarily, when the first ambient illumination value is less than 90 Lux and the second ambient illumination value is less than 0.1 Lux, if the rear illumination value is less than 4400 Lux, then exit the EC; if the rear illumination value is greater than or equal to 4700 Lux, then determine the target anti-glare level as the highest level.

[0103] In this embodiment, the vehicle's environment can be accurately identified through the first ambient illumination value and the second ambient illumination value. When the first ambient illumination value is less than the third threshold and the second ambient illumination value is less than the fourth threshold, it means that the vehicle is in an extremely dark environment. Thus, among the multiple preset anti-glare levels of the rearview mirror, accurately determine the target anti-glare level corresponding to the rear illumination value, providing a more realistic anti-glare effect for the driver.

[0104] In some embodiments, the above-mentioned obtaining the current first ambient illumination value collected by the front windshield sensor may specifically include:

[0105] Obtain the current scattered illumination value and the preset direction illumination value collected by the front windshield sensor. The scattered illumination value is the illumination value of the scattered light in the vehicle's environment, and the preset direction illumination value is the illumination value of the light in the preset direction angle of the vehicle.

[0106] Calculate the scattered illumination value and the preset direction illumination value according to the preset weight coefficient to obtain the first ambient illumination value.

[0107] The above-mentioned preset direction illumination value can be the illumination value of the light in the preset direction angle of the vehicle, where the preset direction angle light can be the forward light of the vehicle's front windshield.

[0108] The above-mentioned calculation of the scattered illumination value and the preset direction illumination value according to the preset weight coefficient to obtain the first ambient illumination value. Exemplarily, it can be that the sum value of 3 / 4 of the scattered illumination value and 1 / 4 of the preset direction illumination value is determined as the first ambient illumination value. In this application, the weight coefficients of the scattered illumination value and the preset direction illumination value in the first ambient illumination value are not limited to 3 / 4 and 1 / 4, and can also be other values set by the user according to actual needs, which are not specifically limited here.

[0109] In this embodiment, through the scattered illumination value of the scattered light in the vehicle's environment and the preset direction illumination value of the light in the preset direction angle of the vehicle, the first ambient illumination value can be accurately calculated, thereby improving the accuracy of determining the target anti-glare level.

[0110] In some embodiments, the above S102 may specifically include:

[0111] In multiple driving scenarios, determine a target driving scenario corresponding to the ambient illumination value, and different driving scenarios are associated with different multiple preset anti-glare levels of the rearview mirror;

[0112] Among the multiple preset anti-glare levels associated with the target driving scenario, determine a target anti-glare level corresponding to the rear illumination value.

[0113] The above-mentioned driving scenarios, by way of example, can be a daytime scenario, an extremely dark scenario, a low-light scenario, and a streetlight-on scenario.

[0114] In the above-mentioned multiple driving scenarios, determining a target driving scenario corresponding to the ambient illumination value, by way of example, when the ambient illumination value ≤ 0.1 lux, the target driving scenario is an extremely dark scenario; when the ambient illumination value ≤ 2.3 lux, the target driving scenario is a low-light scenario; when the ambient illumination value > 2.3 lux, the target driving scenario is a streetlight-on scenario.

[0115] The above-mentioned different driving scenarios are associated with different multiple anti-glare levels of the rearview mirror. For example, the multiple anti-glare levels associated with the extremely dark scenario can be that when the rear illumination value is above 4500, the EC anti-glare level is 9; when the rear illumination value is 4400 - 4500, the EC anti-glare level changes gradually from 1 to 8; when the rear illumination value is below 4400, the EC anti-glare level is 0. The multiple anti-glare levels associated with the streetlight-on scenario can be that when the rear illumination value is above 4700, the EC anti-glare level changes gradually from 1 to 5; when the rear illumination value is below 4700, the EC anti-glare level is 0. The multiple anti-glare levels associated with different driving scenarios in this application are not limited to this and can also be set according to user needs, and no specific limitation is made here.

[0116] As an implementation manner of this application, in order to reduce misoperations caused by environmental changes to the anti-glare adjustment of the vehicle rearview mirror, before the above-mentioned S101, it may further include:

[0117] Obtain the time information of the location where the vehicle is located;

[0118] The above-mentioned S101 may specifically include:

[0119] When the time information is within a preset time period, obtain the current ambient illumination value collected by the vehicle's front sensor, and obtain the current rear illumination value collected by the vehicle's rear sensor.

[0120] The above-mentioned preset time period, by way of example, can be from 6 pm to 7 am the next day in Beijing time. The situation where the time information is within the preset time period, according to the daily law of day and night changes, means that the vehicle is in the night.

[0121] Exemplarily, time information of the vehicle's location is obtained, and the sunrise and sunset times can also be determined according to the local weather signal. Other times of the day except for the period from sunrise to sunset are set as the preset time period. The EC anti-glare function is not activated during the period from sunrise to sunset, that is, the ambient light intensity value and the rear light intensity value collected by the vehicle's front sensor at that time are not obtained. In this embodiment, if the local weather signal is not received, the EC anti-glare function is activated according to the basic settings. For example, the preset time period is from 6 pm to 7 am the next day in Beijing time to activate the EC anti-glare function.

[0122] In this embodiment, it can be set that only when the time information is within the preset time period, the ambient light intensity value currently collected by the vehicle's front sensor is obtained, and the rear light intensity value currently collected by the vehicle's rear sensor is obtained. This conforms to the daily law of day and night changes and can reduce misoperations caused by environmental changes to the anti-glare adjustment of the vehicle rearview mirror.

[0123] To facilitate the understanding of the vehicle rearview mirror anti-glare adjustment method in the embodiments of the present application, the application process of the vehicle rearview mirror anti-glare adjustment method is described herein as follows:

[0124] A rain and light sensor is provided in the front windshield area of the vehicle, a front light sensor is provided in the area facing the front of the vehicle in the front-mounted streaming rearview mirror, and a streaming camera is provided at the rear of the vehicle.

[0125] The vehicle rearview mirror anti-glare is not activated from 7 am to 6 pm in Beijing time. And the in-vehicle terminal can also determine whether the vehicle is in a bright or dark environment through the rain and light sensor signal (4 / 3 ambient light value + 4 / 1 forward light value, that is, the first ambient light intensity value). Among them, when the rain and light sensor signal is greater than or equal to 1200 lux, it is a bright environment; when the rain and light sensor signal is less than 1200 lux, it is a dark environment.

[0126] In a dark environment, the target anti-glare level can also be determined according to the light intensity value collected by the front light sensor of the streaming rearview mirror and the rear light intensity value collected by the camera at the rear of the vehicle. Specifically, it includes:

[0127] When the light intensity value of the front light sensor of the streaming rearview mirror is less than or equal to 0.1 and the rain and light is less than 90, it corresponds to an extremely dark scene: when the rear light intensity value is above 4000: EC function level 9; 3800 - 4000: EC function levels 1 - 8; below 3800, EC function level 0 (or not activated). In an extremely dark scene, when a vehicle comes from behind, the front of the vehicle is extremely dark, and the difference from the lights of the vehicle coming from behind is too large. Therefore, compared with other scenes, the same size of the rear light intensity value requires a higher level of EC function to be activated.

[0128] The light intensity value of the front light sensor of the streaming media interior rearview mirror is less than or equal to 2.5, corresponding to the low light scenario (such as in the dim light at dusk): the rear illuminance value is above 4500: the EC function is in gear 9; 4300 - 4500: gears 1 - 8.

[0129] The light intensity value of the front light sensor of the streaming media interior rearview mirror is greater than 2.5, corresponding to the scenario when street lights are on: the rear illuminance value is above 4700: the EC function is in gears 1 - 5; it does not enter the EC mode when the rear illuminance value is below 4700.
