It should be noted that the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0068] In the following description, many specific details are set forth to facilitate a full understanding of the present disclosure, but the present disclosure may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present disclosure, rather than all of the embodiments.

Any embodiment or design described as "exemplary" or "for example" in the embodiments of the present disclosure should not be interpreted as being more preferred or more advantageous than other embodiments or designs.

In addition, in the description of the embodiments of the present disclosure, unless otherwise specified, the meaning of "multiple" refers to two or more.

[0071] In some embodiments, Figure 1 As shown, a screen brightness adjustment method is provided, comprising the following steps S11-S14:

[0072] S11, obtaining a first light intensity and a second light intensity.

[0073] Among them, the first light intensity is the light intensity of the current environment collected in real time by the light sensor, and the first light intensity is the light intensity of the current environment collected in real time by the rainfall sensor.

[0074] Specifically, the function of the light sensor is to adjust the screen brightness of the vehicle system according to the environment. The rain sensor is generally used to monitor the amount of rain, and the vehicle wiper controller can automatically adjust the speed and sensitivity of the wiper according to the amount of rain; it is also used to monitor light changes, and the vehicle headlight control system can automatically control the opening and closing of the headlights according to the light intensity. Compared with the light sensor, the rain sensor obtains less accurate light intensity. When the light sensor on the screen in the car is abnormal, the vehicle's rain sensor is used as a backup interface for adjusting the brightness. The light intensity of the current environment is collected in real time through the light sensor, that is, the first light intensity. The light intensity of the current environment is collected in real time through the rain sensor, that is, the second light intensity.

[0075] For example, the first light intensity collected in real time by the light sensor may be 50 Lux (lumen: a unit indicating the ambient brightness value), or 150 Lux, or other reasonable brightness values, which are only examples here and are not specifically limited. The second light intensity collected in real time by the rain sensor may be 50 Lux, or 150 Lux, or 200 Lux, or other reasonable brightness values, which are only examples here and are not specifically limited.

[0076] S12: Determine whether the first light intensity matches the second light intensity.

[0077] In some embodiments, the above step S12 (determining whether the first light intensity matches the second light intensity) can be implemented in the following manner:

[0078] a. According to a light intensity level table, obtain the first light intensity level corresponding to the second light intensity.

[0079] The light intensity level table includes: the correspondence between the light intensity collected by the rain sensor and the light intensity level. That is, the light intensity interval in Table 1 is the light intensity interval corresponding to the light intensity collected by the rain sensor, and the light intensity level is the light intensity level corresponding to the light intensity interval.

[0080] Specifically, since the light intensity obtained by the rain sensor has low accuracy, the second light intensity is divided into preset light intensity intervals to obtain the first light intensity level. According to the light intensity level table, the first light intensity level corresponding to the second light intensity is obtained.

[0081] Exemplarily, referring to Table 1, Table 1 is a light intensity level table, and the light intensity level table includes: the correspondence between the light intensity collected by the rain sensor and the light intensity level, that is, first obtain the second light intensity collected by the rain sensor, then determine the light intensity interval corresponding to the second light intensity in Table 1 according to the second light intensity, and then determine the first light intensity level according to the light intensity interval corresponding to the second light intensity. Assuming that the second light intensity is 60Lux, and the interval to which it belongs is (1, 100], the first light intensity level corresponding to the second light intensity is 1; assuming that the second light intensity is 150Lux, and the interval to which it belongs is (100, 200], the first light intensity level corresponding to the second light intensity is 2; assuming that the second light intensity is 220Lux, and the interval to which it belongs is (200, 300], the first light intensity level corresponding to the second light intensity is 3; assuming that the second light intensity is 360Lux, and the interval to which it belongs is (300, 400], the first light intensity level corresponding to the second light intensity is 4, and so on, which will not be repeated here.

[0082] Table 1

[0083] Light intensity level Light intensity range 1 (1，100] 2 (100，200] 3 (200，300] 4 (300，400]

[0084] b. Determine whether the first light intensity matches the first light intensity level according to the light intensity mapping relationship table.

[0085] The light intensity mapping relationship table includes: a correspondence between a preset light intensity interval and a first light intensity level, wherein the preset light intensity interval is a light intensity interval corresponding to the light intensity collected by the light sensor.

[0086] Specifically, according to the light intensity mapping relationship table, a first preset light intensity interval corresponding to the first light intensity and a second preset light intensity interval corresponding to the first light intensity level are determined.

[0087] Exemplarily, refer to Table 2, which is a light intensity mapping relationship table. One possible implementation is: assuming that the first light intensity is 30 Lux, the light intensity interval corresponding to the first light intensity is (1, 50]. Assuming that the second light intensity is 60 Lux, it can be seen from Table 1 that the first light intensity level corresponding to the second light intensity is 1, and the preset light intensity interval corresponding to the first light intensity level is (1, 50]. Another possible implementation is: assuming that the first light intensity is 30 Lux, it can be seen from Table 2 that the light intensity interval corresponding to the first light intensity is (1, 50]. Assuming that the second light intensity is 120 Lux, it can be seen from Table 1 that the first light intensity level corresponding to the second light intensity is 2, and the preset light intensity interval corresponding to the first light intensity level is (51, 150].

[0088] Table 2

[0089] Preset light intensity range Preset screen brightness First light intensity level (1，50] 10 1 (51，150] 50 2 (151，250] 150 3 (251，350] 200 4

[0090] In some embodiments, the above step (determining whether the first light intensity matches the first light intensity level according to the light intensity mapping relationship table) can be implemented as follows:

[0091] Determine, according to the light intensity mapping relationship table, a first preset light intensity interval corresponding to the first light intensity and a second preset light intensity interval corresponding to the first light intensity level;

[0092] Determining whether the first preset light intensity interval is consistent with the second preset light intensity interval;

[0093] If the first preset light intensity interval is consistent with the second preset light intensity interval, determining that the first light intensity matches the first light intensity level;

[0094] If the first preset light intensity interval is inconsistent with the second preset light intensity interval, it is determined that the first light intensity does not match the first light intensity level.

[0095] Specifically, since the light intensity mapping relationship table includes: the correspondence between the light intensity interval corresponding to the first light intensity, and the first light intensity level, the first preset light intensity interval corresponding to the first light intensity and the second preset light intensity interval corresponding to the first light intensity level can be determined according to the light intensity mapping relationship table, and then it is determined whether the first preset light intensity interval is consistent with the second preset light intensity interval. If the first preset light intensity interval is consistent with the second preset light intensity interval, it is determined that the first light intensity matches the first light intensity level; if the first preset light intensity interval is inconsistent with the second preset light intensity interval, it is determined that the first light intensity does not match the first light intensity level.

[0096] Exemplarily, a possible implementation is: assuming that the first light intensity obtained is 60 Lux and the first light intensity level is 2, according to Table 2, the first preset light intensity interval corresponding to the first light intensity 60 Lux is (51, 150], and the second preset light intensity interval corresponding to the first light intensity level 2 is (51, 150]. Since the first preset light intensity interval determined according to Table 2 is (51, 150], and the second preset light intensity interval corresponding to the first light intensity level is (51, 150], the first preset light intensity interval is consistent with the second preset light intensity interval, and therefore, it is determined that the first light intensity matches the first light intensity level.

[0097] Another possible implementation is: assuming that the first light intensity obtained is 200 Lux and the first light intensity level is 1, according to Table 2, the first preset light intensity interval corresponding to the first light intensity 200 Lux is (151, 250], and the second preset light intensity interval corresponding to the first light intensity level 1 is (1, 50]. Since the first preset light intensity interval determined according to Table 2 is (151, 250], and the second preset light intensity interval corresponding to the first light intensity level is (1, 50], the first preset light intensity interval is inconsistent with the second preset light intensity interval. Therefore, it is determined that the first light intensity does not match the first light intensity level.

[0098] S13. When the first light intensity matches the second light intensity, adjusting the current screen brightness to the screen brightness corresponding to the first light intensity.

[0099] In some embodiments, the light intensity mapping relationship table further includes: a correspondence between the preset light intensity interval and the preset screen brightness. The above step S13 (when the first light intensity matches the second light intensity, adjusting the current screen brightness to the screen brightness corresponding to the first light intensity) can be implemented as follows:

[0100] If the first light intensity matches the first light intensity level, determining a first preset screen brightness corresponding to the first preset light intensity interval according to the light intensity mapping relationship table;

[0101] Adjust the current screen brightness to the first preset screen brightness; wherein the first preset screen brightness is the screen brightness corresponding to the first light intensity.

[0102] Specifically, if the first light intensity matches the first light intensity level, it means that the data currently obtained by the light sensor is reliable data. Since the accuracy of the rain sensor is lower than that of the light sensor, it is preferred to adjust the screen brightness according to the light intensity obtained by the light sensor. According to the correspondence between the first light intensity and the preset screen brightness in the light intensity mapping relationship table, the current screen brightness is adjusted to the first preset screen brightness.

[0103] For example, assuming that the current screen brightness is 50, if the first light intensity obtained is 200 Lux, and the first light intensity level is 3, it can be seen from Table 2 that the first preset light intensity interval corresponding to the first light intensity is (151, 250], and the first preset screen brightness corresponding to the first preset light intensity interval (151, 250] is 150, so the current screen brightness 50 is adjusted to the first preset screen brightness 150; if the first light intensity obtained is 100 Lux, and the first light intensity level is 2, it can be seen from Table 2 that the first light intensity is The first preset light intensity interval is (51, 150], and the first preset screen brightness corresponding to the first preset light intensity interval (51, 150] is 50, so the current screen brightness remains unchanged at 50; if the first light intensity obtained is 40Lux, and the first light intensity level is 1, according to Table 2, the first preset light intensity interval corresponding to the first light intensity is (1, 50], and the first preset screen brightness corresponding to the first preset light intensity interval (1, 50] is 10, so the current screen brightness 50 is adjusted to the first preset screen brightness 10.

[0104] S14. When the first light intensity does not match the second light intensity, adjusting the current screen brightness to the screen brightness corresponding to the second light intensity.

[0105] In some embodiments, the above step S14 (when the first light intensity does not match the second light intensity, adjusting the current screen brightness to the screen brightness corresponding to the second light intensity) can be implemented as follows:

[0106] If the first light intensity does not match the first light intensity level, determining a second preset screen brightness corresponding to the second preset light intensity interval according to the light intensity mapping relationship table;

[0107] Adjust the current screen brightness to the second preset screen brightness; wherein the second preset screen brightness is the screen brightness corresponding to the second light intensity.

[0108] Specifically, if the first light intensity does not match the first light intensity level, it means that the data currently obtained by the light sensor is unreliable data, that is, the data obtained by the light sensor is abnormal data. Although the accuracy of the rain sensor is lower than that of the light sensor, the data it obtains is more reliable than the value obtained by the faulty light sensor. Therefore, it is necessary to rely on the data obtained by the rain sensor to adjust the screen brightness. According to the correspondence between the first light intensity level and the preset screen brightness in the light intensity mapping relationship table, the current screen brightness is adjusted to the second preset screen brightness.

[0109] For example, assuming that the current screen brightness is 50, if the first light intensity obtained is 200 Lux, and the first light intensity level is 1, it can be seen from Table 2 that the second preset screen brightness corresponding to the first light intensity level is 10, so the current screen brightness of 50 is adjusted to the second preset screen brightness of 10; if the first light intensity obtained is 200 Lux, and the first light intensity level is 2, it can be seen from Table 2 that the second preset screen brightness corresponding to the first light intensity level is 50, so the current screen brightness remains unchanged at 50; if the first light intensity obtained is 200 Lux, and the first light intensity level is 4, it can be seen from Table 2 that the second preset screen brightness corresponding to the first light intensity level is 200, so the current screen brightness of 50 is adjusted to the second preset screen brightness of 200.

[0110] The screen brightness adjustment method provided by the present disclosure obtains a first light intensity and a second light intensity, wherein the first light intensity is the light intensity of the current environment collected in real time by a light sensor, and the second light intensity is the light intensity of the current environment collected in real time by a rain sensor, and determines whether the first light intensity matches the second light intensity; when the first light intensity matches the second light intensity, the current screen brightness is adjusted to the screen brightness corresponding to the first light intensity; when the first light intensity does not match the second light intensity, the current screen brightness is adjusted to the screen brightness corresponding to the second light intensity. The first light intensity obtained by the light sensor is calibrated and judged by the second light intensity obtained by the rain sensor. Since the accuracy of the rain sensor is lower than that of the light sensor, when the first light intensity matches the second light intensity, it is determined that the light sensor is not faulty, that is, the data obtained by the light sensor is trustworthy data. The current screen brightness is further adjusted based on the trustworthy data obtained by the light sensor. When the first light intensity does not match the second light intensity, it is determined that the light sensor is faulty, that is, the data obtained by the light sensor is abnormal data. Although the accuracy of the rain sensor is lower than that of the light sensor, the data of the rain sensor is trustworthy data. Therefore, the current screen brightness is adjusted based on the trustworthy data obtained by the rain sensor at this time, thereby solving the problem of abnormal changes in screen brightness due to abnormal values ​​reported by the light sensor, and further improving the user experience.

[0111] In some embodiments, the above step S14 (if the first light intensity does not match the first light intensity level) further includes the following implementation:

[0112] Within a preset time period, periodically obtain a third light intensity of the current environment collected by the light sensor and a fourth light intensity of the current environment collected in real time by the rain sensor, and obtain a second light intensity level corresponding to the fourth light intensity according to the light intensity level table;

[0113] Determining the expected light intensity corresponding to the second light intensity level according to the light intensity mapping relationship table;

[0114] Calculating according to the third light intensity and the expected light intensity corresponding to the second light intensity level to obtain a light intensity difference;

[0115] Within a preset time period, obtaining the actual number of times the light intensity difference is greater than a preset intensity threshold;

[0116] When the actual number is greater than the preset number, it is determined that the light sensor is faulty.

[0117] Among them, the preset duration can be set according to actual needs, for example, it can be set to 10 seconds, 20 seconds, 60 seconds, or it can be set to other reasonable values, which are not specifically limited here. The preset intensity threshold can be set according to real-time needs, for example, the preset intensity threshold can be set to 50Lux, 100Lux, 150Lux, etc., or it can be set to other reasonable values, which are not specifically limited here. The preset number of times can be set according to real-time needs, for example, the preset number of times can be set to 5 times, 10 times, 20 times, etc., or it can be set to other reasonable values, which are not specifically limited here.

[0118] Specifically, first, within a preset time period, the third light intensity of the current environment collected by the light sensor and the fourth light intensity of the current environment collected by the rain sensor in real time are periodically obtained, and according to the light intensity level table, with reference to Table 1, the second light intensity level corresponding to the fourth light intensity is obtained. Since in this embodiment, the third light intensity does not match the second light intensity level, it is necessary to rely on the data obtained by the rain sensor to adjust the screen brightness, and specifically obtain the expected light intensity corresponding to the third light intensity according to the second light intensity level, and obtain the light intensity difference according to the difference between the first light intensity and the expected light intensity. Further, within the preset time period, the actual number of times the light intensity difference is greater than the preset intensity threshold is obtained; when the actual number is greater than the preset number, it is determined that the light sensor is faulty.

[0119] Exemplarily, within 5 seconds, the third light intensity and the second light intensity level are periodically obtained. Assuming that the third light intensity and the second light intensity level are obtained twice per second, the third light intensity and the second light intensity level are obtained 10 times in 5 seconds. Assuming that the third light intensity is 200 Lux and the second light intensity level is 1, it can be seen from Table 2 that the expected light intensity corresponding to the first light intensity determined according to the second light intensity level 1 is 50 Lux, so according to the third light intensity and the expected light intensity, the light intensity difference is calculated to be 150 Lux. Further, assuming that the preset intensity threshold is 100 Lux and the preset number of times is 10 times, a total of 20 data are obtained within 10 seconds, of which the actual number of times the light intensity difference is greater than 100 Lux is 13 times. Since the actual number is greater than the preset number, it is determined that the light sensor has failed.

[0120] Further, a fault message is sent to the server; the fault message is used to prompt that the light sensor has a fault.

[0121] Specifically, when the light sensor fails, a fault message is sent to the server, and the server collects data for reference as subsequent maintenance data.

[0122] The screen brightness adjustment method provided by the present disclosure obtains a first light intensity and a second light intensity, wherein the first light intensity is the light intensity of the current environment collected in real time by a light sensor, and the second light intensity is the light intensity of the current environment collected in real time by a rain sensor, and determines whether the first light intensity matches the second light intensity; when the first light intensity matches the second light intensity, the current screen brightness is adjusted to the screen brightness corresponding to the first light intensity; when the first light intensity does not match the second light intensity, the current screen brightness is adjusted to the screen brightness corresponding to the second light intensity. The first light intensity obtained by the light sensor is calibrated and judged by the second light intensity obtained by the rain sensor. Since the accuracy of the rain sensor is lower than that of the light sensor, when the first light intensity matches the second light intensity, it is determined that the light sensor is not faulty, that is, the data obtained by the light sensor is trustworthy data. The current screen brightness is further adjusted based on the trustworthy data obtained by the light sensor. When the first light intensity does not match the second light intensity, it is determined that the light sensor is faulty, that is, the data obtained by the light sensor is abnormal data. Although the accuracy of the rain sensor is lower than that of the light sensor, the data of the rain sensor is trustworthy data. Therefore, the current screen brightness is adjusted based on the trustworthy data obtained by the rain sensor at this time, thereby solving the problem of abnormal changes in screen brightness due to abnormal values ​​reported by the light sensor, and further improving the user experience.
