[0066] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0067] Before introducing the control method, device, vehicle and storage medium of the rearview mirror shown in the embodiments of the present disclosure, the application scenarios of the embodiments of the present disclosure are first introduced.

[0068] The application scenario of the present disclosure is that when a vehicle is driving in a dark environment such as at night, dusk, on a cloudy day, in a tunnel, or in a garage, if the rear vehicle turns on the high beam, the strong light from the rear side will be reflected into the driver's eyes through the inside and outside rearview mirrors, causing discomfort and loss of vision to the driver, interfering with the driver's normal driving. The executor of the present disclosure may be the vehicle's whole vehicle central computing domain controller VCCD, which performs anti-glare control of the vehicle's rearview mirror through the whole vehicle VCCD, and uses the whole vehicle light sensor and / or rearview camera to obtain the ambient light intensity around the vehicle and the glare intensity of the rearview mirror. There is no need to install an ambient light sensor, a glare sensor, and a circuit board in the rearview mirror, which can reduce the weight, volume, and cost of the rearview mirror. The rearview mirror in the present disclosure may include an interior rearview mirror and / or an exterior rearview mirror. When the rearview mirror includes an interior rearview mirror and an exterior rearview mirror, the interior rearview mirror and the exterior rearview mirror may be independently controlled.

[0069] Figure 1 is a flow chart of a method for controlling a rearview mirror according to an exemplary embodiment. Figure 1 As shown, the method may include the following steps.

[0070] In step 101, a glare intensity signal corresponding to a rearview mirror of a vehicle is obtained, where the glare intensity signal is used to characterize the light intensity of light projected on the rearview mirror.

[0071] For example, a target image can be captured by a camera installed on a rearview mirror, and then the brightness information of the target image can be converted into a glare light intensity signal through formula conversion, wherein the camera can be a camera installed on an interior rearview mirror, and the glare light intensity signal can be used to characterize the light intensity of the light projected on the rearview mirror. In this way, the glare light intensity is obtained by using the original camera in the rearview mirror, and there is no need to install an additional glare sensor on the rearview mirror, which can reduce the thickness of the lens of the rearview mirror and make the appearance more refined.

[0072] In step 102, a target voltage is determined according to the glare intensity signal.

[0073] In step 103 , the rearview mirror is controlled according to the target voltage to adjust the reflectivity of the rearview mirror.

[0074] For example, applying different voltages at both ends of the rearview mirror will cause the rearview mirror lens to change color, thereby changing the reflectivity of the rearview mirror. The correspondence between glare illumination intensity and voltage can be established in advance. For different glare illumination intensities, the target voltage corresponding to the glare illumination intensity can be determined according to the correspondence, and the pressure applied to both ends of the rearview mirror can be adjusted to the target voltage to adjust the reflectivity of the rearview mirror. In this way, under different glare illumination intensities, the illumination intensity of the glare projected on the rearview mirror after reflection is more comfortable for the human eye, avoiding the impact of glare on the driver, and improving the safety and comfort of vehicle driving.

[0075] In some embodiments, the target voltage corresponding to the glare light intensity signal can be determined by stepless dimming. First, multiple sets of sample data can be obtained in advance through actual measurement, and each set of sample data can include a sample light intensity and a sample voltage corresponding to the sample light intensity, wherein when a sample voltage corresponding to the sample light intensity is applied to both ends of the rearview mirror, the light intensity of the light reflected by the rearview mirror is less than the first preset light intensity threshold, that is, the sample voltage can ensure that the light corresponding to the sample light intensity is more comfortable for the human eye after being reflected by the rearview mirror. Based on the discrete points corresponding to the multiple sets of sample data, a linear or nonlinear interpolation algorithm can be used to obtain a variation function of the glare light intensity signal-voltage signal, and a voltage signal corresponding to the glare light intensity signal can be output according to the variation function and returned to the controller to control the color change of the rearview mirror.

[0076] In other embodiments, the target voltage corresponding to the glare light intensity signal can be determined by a multi-level dimming method. First, multiple light intensity intervals can be pre-defined, and a preset correspondence relationship between each light intensity interval and a voltage value can be established, wherein the number of light intensity intervals can be set according to actual conditions, and each light intensity interval can correspond to a voltage value. After obtaining the glare light intensity indicated by the glare light intensity signal, the target light intensity interval in which the glare light intensity is located can be determined first, and then the voltage value corresponding to the target light intensity interval can be searched in the preset correspondence relationship, and the voltage value is used as the target voltage.

[0077] It should be noted that the dimming method to be used can be determined based on the computing power of the on-board chip and the quality of the glare light intensity signal. If the computing power of the on-board chip is low, a multi-level dimming method can be used to determine the target voltage corresponding to the glare light intensity signal. If the computing power of the on-board chip is high and the quality of the glare light intensity signal is good, a stepless dimming method can be used to determine the target voltage corresponding to the glare light intensity signal. If the computing power of the on-board chip is high and the quality of the glare light intensity signal is poor, a multi-level dimming method can be used to determine the target voltage corresponding to the glare light intensity signal.

[0078] In summary, the present disclosure first obtains a glare light intensity signal corresponding to the rearview mirror of the vehicle, wherein the glare light intensity signal is used to characterize the light intensity of the light projected on the rearview mirror, and then determines a target voltage according to the glare light intensity signal, and controls the rearview mirror according to the target voltage, thereby adjusting the reflectivity of the rearview mirror. The present disclosure automatically adjusts the reflectivity of the rearview mirror under different glare light intensities, thereby ensuring that the reflected light of the rearview mirror is more comfortable for the human eye in different driving environments, and can improve the safety and comfort of vehicle driving.

[0079] Figure 2 is a flow chart of another method for controlling a rearview mirror according to an exemplary embodiment. Figure 2 As shown, step 102 can be implemented in the following manner:

[0080] In step 1021, the signal noise of the glare light intensity signal is determined, and the signal noise of the glare light intensity signal is used to indicate the signal quality of the glare light intensity signal.

[0081] In step 1022, a target voltage is determined according to the glare intensity signal and the signal noise.

[0082] For example, the signal noise of the glare light intensity signal can be used to indicate the signal quality of the glare light intensity signal. The smaller the signal noise of the glare light intensity signal, the better the signal quality of the glare light intensity signal. The larger the signal noise of the glare light intensity signal, the worse the signal quality of the glare light intensity signal. When the signal noise of the glare light intensity signal is small, the glare light intensity signals in different scenes have obvious distinction. When the signal noise of the glare light intensity signal is large, the glare light intensity signal is only clearly distinguished in individual scenes. Therefore, the signal noise of the glare light intensity signal corresponding to the rearview mirror of the vehicle can be obtained, and the appropriate adjustment method can be determined according to the signal noise, and the target voltage corresponding to the glare light intensity signal can be determined according to the adjustment method.

[0083] According to an embodiment shown in the present disclosure, when the signal noise of the glare light intensity signal is less than a preset noise threshold, a stepless dimming scheme can be adopted to determine the target voltage corresponding to the glare light intensity signal according to a first preset relationship, wherein the first preset relationship may include a corresponding relationship between light intensity and voltage.

[0084] The first preset relationship can be determined in the following manner:

[0085] Step A, obtaining a plurality of sample light intensities and a sample voltage corresponding to each sample light intensity, wherein when the sample voltage corresponding to the sample light intensity is applied to the rearview mirror, the light intensity of the light reflected by the rearview mirror is less than a first preset light intensity threshold.

[0086] Step B: obtaining a first preset relationship by fitting a plurality of sample light intensities and a plurality of sample voltages.

[0087] For example, actual measurements can be conducted based on the photochromic lenses of the internal and external rearview mirrors. Applying different voltages at both ends of the lenses will cause the rearview mirror lenses to change color. The light intensity projected onto the mirror surface under different glares is measured respectively. A varying voltage is applied according to the light intensity. The lenses will produce different color changing effects. The light intensity on the mirror surface, the value of the glare sensor, and the corresponding voltage value under the appropriate color changing effect can be recorded respectively. Among them, the light intensity on the mirror surface can be understood as the light intensity after being reflected by the rearview mirror lens, the value of the glare sensor can characterize the light intensity projected on the rearview mirror surface, and the voltage value is the voltage applied to both ends of the rearview mirror lens. The appropriate color changing effect can be understood as the light reflected into the human eye by the rearview mirror surface under the color changing effect is more comfortable for the human eye. For example, when the light intensity on the mirror surface is less than the first preset light intensity threshold, it can be considered that the current mirror surface has achieved an appropriate color changing effect.

[0088] In some embodiments, a plurality of sample illumination intensities measured and a sample voltage corresponding to each sample illumination intensity can be obtained, and a linear or nonlinear interpolation algorithm can be used to obtain a variation function of glare illumination intensity-voltage, and the variation function can be used as a first preset relationship. After obtaining the glare light intensity signal, a voltage signal corresponding to the glare light intensity can be output through the variation function and returned to the controller to control the color change of the rearview mirror. In this way, when the quality of the glare light intensity signal is good, the reflectivity of the rearview mirror can be continuously adjusted under different glare light intensities, thereby more accurately controlling the color change effect of the rearview mirror, and ensuring that the light reflected by the rearview mirror is within the range comfortable to the human eye under different glare light intensities, thereby improving driving safety.

[0089] According to another embodiment shown in the present disclosure, when the signal noise of the glare light intensity signal is greater than or equal to the preset noise threshold, the target reflectivity interval corresponding to the glare light intensity signal can be determined according to the second preset relationship, wherein the second preset relationship includes the corresponding relationship between the light intensity and the reflectivity. The target voltage corresponding to the target reflectivity interval is determined according to the third preset relationship, wherein the third preset relationship includes the corresponding relationship between the reflectivity interval and the voltage.

[0090] For example, when the signal quality of the glare light intensity signal is poor, a multi-level dimming solution can be adopted. First, the target reflectivity interval corresponding to the glare light intensity signal is determined according to the second preset relationship, and then the target voltage corresponding to the target reflectivity interval is determined according to the third preset relationship. When the number of target reflectivity intervals is large enough, due to the delay in the color change of the rearview mirror, continuous stepless dimming can be approximately simulated.

[0091] In some embodiments, the corresponding relationship between glare illumination intensity and reflectivity can be established as the second preset relationship by measuring and recording the light intensity on the mirror surface, the value of the glare sensor, and the corresponding voltage value under the appropriate color change effect. In the second preset relationship, the reflectivity of the rearview mirror corresponding to the glare illumination intensity can ensure that the glare is comfortable to the human eye after being reflected by the rearview mirror lens. In addition, multiple different reflectivity intervals can be pre-determined based on the reflectivity-voltage change curve of the rearview mirror color-changing glass by calibration. For a specific reflectivity interval, a fixed voltage value is pre-set to obtain a third preset relationship, that is, in the third preset relationship, multiple reflectivities in each reflectivity interval correspond to the same voltage value.

[0092] After obtaining the glare light intensity signal, the reflectivity corresponding to the glare light intensity can be searched in the second preset relationship according to the glare light intensity indicated by the glare light intensity signal, and the target reflectivity interval of the reflectivity can be determined, and then the target voltage corresponding to the target reflectivity interval can be searched in the third preset relationship.

[0093] Figure 3 is a flow chart of another method for controlling a rearview mirror according to an exemplary embodiment. Figure 3 As shown, the method also includes:

[0094] In step 104, an ambient light intensity signal is acquired, where the ambient light intensity signal indicates the light intensity of the environment in which the vehicle is located.

[0095] In step 105, when the light intensity indicated by the ambient light intensity signal is less than a second preset light intensity threshold, the anti-glare function is turned on.

[0096] Accordingly, one implementation of step 101 may be:

[0097] When the anti-glare function is turned on, the glare intensity signal corresponding to the vehicle's rearview mirror is obtained.

[0098] For example, an ambient light intensity signal of the vehicle's environment can be obtained through an ambient light sensor, wherein the ambient light sensor can be an independent sensor installed on the vehicle body, or a five-in-one sunlight and rainfall sensor, etc., which is not specifically limited in the present disclosure. By using the original ambient light sensor of the vehicle, there is no need to install an additional ambient light sensor on the rearview mirror, which can reduce the volume, weight and cost of the rearview mirror. If the light intensity indicated by the ambient light intensity signal is less than the second preset light intensity threshold, it means that the current ambient light is weak, and the glare reflected on the rearview mirror entering the human eye will cause discomfort, so the anti-glare function can be turned on. When the anti-glare function is turned on, steps 101 to 103 can be executed.

[0099] In summary, the present disclosure first obtains a glare light intensity signal corresponding to the rearview mirror of the vehicle, wherein the glare light intensity signal is used to characterize the light intensity of the light projected on the rearview mirror, and then determines a target voltage according to the glare light intensity signal, and controls the rearview mirror according to the target voltage, thereby adjusting the reflectivity of the rearview mirror. The present disclosure automatically adjusts the reflectivity of the rearview mirror under different glare light intensities, thereby ensuring that the reflected light of the rearview mirror is more comfortable for the human eye in different driving environments, and can improve the safety and comfort of vehicle driving.
