The embodiment of the application provides a screen backlight brightness adjusting method, which is applied to a vehicle-mounted system.
Fig. 1 is a flowchart illustrating a method for adjusting brightness of a backlight of a screen according to an embodiment of the present application. As shown in fig. 1, the method includes steps S110 to S140.
S110, continuously collecting the ambient light intensity values of preset sampling times in a first preset time to form an ambient light intensity value sequence.
In this embodiment, a photosensitive sensor device is provided on the vehicle system for detecting the current ambient light intensity. Wherein, the car machine system controls the photosensitive sensor device to collect the ambient light intensity value in real time or periodically. When the vehicle machine system of the vehicle is started, the ambient light intensity values of the preset sampling times can be continuously acquired within the first preset time through the photosensitive sensor device to form an ambient light intensity value sequence, the photosensitive sensor device samples the ambient light intensity every 100ms, and therefore the ambient light intensity value sequence of the preset sampling times is continuously acquired within the first preset time, and the brightness value change trend information corresponding to the ambient light intensity value sequence can be conveniently acquired by the following vehicle machine system.
The first preset time and the preset sampling times can be a time threshold and a sampling times threshold set by a vehicle-mounted system or a time threshold and a sampling times threshold set manually by a user.
In one embodiment, step S110 includes:
acquiring a first time period, a second time period and a third time period which are included in the first preset time;
acquiring a first environmental light intensity value subsequence corresponding to the first time period, a second environmental light intensity value subsequence corresponding to the second time period and a third environmental light intensity value subsequence corresponding to the third time period;
and the first environment light intensity value subsequence, the second environment light intensity value subsequence and the third environment light intensity value subsequence sequentially form the environment light intensity value sequence.
In this embodiment, since the method for adjusting the brightness of the screen backlight adjusts the brightness of the screen backlight only based on the ambient light intensity value acquired by the photosensitive sensor, the problem that the optimization adjustment of the brightness of the screen backlight is not complete is easy to occur. For example, in the driving process, a user shields natural environment light due to the problems of object placement angles and the like in the vehicle, so that parameters of the photosensitive sensor for collecting the environment light intensity value are inaccurate, and further a screen backlight brightness adjustment error is easy to cause. Thus, in order to improve the accuracy of the screen backlight brightness adjustment, a sub-sequence of ambient light intensity values for a plurality of time periods is acquired within a first preset time.
The first preset time may include a plurality of time periods of the subsequence of the ambient light intensity values, where the plurality of time periods included in the first preset time are not specifically limited.
Preferably, the first time period, the second time period and the third time period included in the first preset time are acquired; and obtaining a first sub-sequence of ambient light intensity values corresponding to the first time period, a second sub-sequence of ambient light intensity values corresponding to the second time period, and a third sub-sequence of ambient light intensity values corresponding to the third time period; and the first environmental light intensity value subsequence, the second environmental light intensity value subsequence and the third environmental light intensity value subsequence sequentially form the environmental light intensity value sequence, so that the vehicle-mounted system can more accurately judge the brightness value change trend information corresponding to the environmental light intensity value sequence based on the environmental light intensity value subsequences of a plurality of time periods.
S120, obtaining brightness value change trend information corresponding to the environment light intensity value sequence, and obtaining a sampling effectiveness detection result corresponding to the environment light intensity value sequence.
In this embodiment, the vehicle-mounted system acquires an ambient light intensity value sequence acquired by the photosensitive sensor device, and determines that a mode of screen backlight brightness matching is a night mode or a daytime mode according to brightness value change trend information corresponding to the ambient light intensity value sequence. The brightness value change trend information corresponding to the environment light intensity value sequence is bright- > dark or dark- > bright. When the brightness value change trend information corresponding to the environment light intensity value sequence is bright- > dark, the mode of screen backlight brightness matching is a night mode; when the brightness value change trend information corresponding to the environment light intensity value sequence is dark- > bright, the screen backlight brightness matching mode is a daytime mode.
In addition, after the vehicle-mounted system determines the mode of the screen matching of the vehicle-mounted system, a sampling effectiveness detection result corresponding to the environment light intensity value sequence is obtained according to the environment light intensity value sequence, so that the vehicle-mounted system adjusts the backlight brightness of the screen to a corresponding daytime mode or night mode according to the matched mode and the sampling effectiveness detection result corresponding to the environment light intensity value sequence.
In an embodiment, as a first embodiment of obtaining the sampling validity detection result corresponding to the ambient light intensity value sequence in step S120, step S120 includes:
acquiring a preset daytime mode light intensity threshold value or a preset night mode light intensity threshold value;
acquiring the total number of the ambient light intensity values included in the ambient light intensity value sequence, and marking the total number as a first numerical value;
acquiring the total number of the ambient light intensity values which are larger than the daytime mode light intensity threshold in the ambient light intensity value sequence, and recording the total number as a second numerical value;
acquiring the total number of the ambient light intensity values smaller than the night mode light intensity threshold in the ambient light intensity value sequence, and marking the total number as a third numerical value;
if the ratio of the second numerical value to the first numerical value is greater than or equal to a preset first ratio threshold, or if the ratio of the third numerical value to the first numerical value is greater than or equal to a preset second ratio threshold, judging that the sampling effectiveness detection result is a sampling effectiveness result;
And if the ratio of the second value to the first value is smaller than the first ratio threshold, or if the ratio of the third value to the first value is smaller than the second ratio threshold, judging that the sampling validity detection result is a sampling invalidity result.
In this embodiment, the obtaining of the sampling validity detection result corresponding to the ambient light intensity value sequence may specifically be performed by: judging the ratio of the total number of the ambient light intensity values which are larger than the daytime mode light intensity threshold value in the ambient light intensity value sequence to the total number of the ambient light intensity values which are included in the ambient light intensity value sequence and the size of a preset first proportional threshold value, or judging the ratio of the total number of the ambient light intensity values which are smaller than the night mode light intensity threshold value in the ambient light intensity value sequence to the total number of the ambient light intensity values which are included in the ambient light intensity value sequence and the size of a preset second proportional threshold value, so as to determine whether the sampling effectiveness detection result is a sampling effectiveness result.
For example: when the total number of the ambient light intensity values included in the ambient light intensity value sequence is 10, the total number of the ambient light intensity values greater than the daytime mode light intensity threshold in the ambient light intensity value sequence is 8, and the preset first ratio threshold is 3/5, it is known that the ratio of the total number of the ambient light intensity values greater than the daytime mode light intensity threshold in the ambient light intensity value sequence to the total number of the ambient light intensity values included in the ambient light intensity value sequence is 4/5 and greater than the preset first ratio threshold is 3/5, and the vehicle-to-vehicle system can determine that the sampling effectiveness detection result is a sampling effectiveness result.
In an embodiment, as a second embodiment of obtaining the sampling validity detection result corresponding to the ambient light intensity value sequence in step S120, step S120 includes:
acquiring a preset daytime mode light intensity threshold value or a preset night mode light intensity threshold value;
acquiring the total number of the ambient light intensity values which are larger than the daytime mode light intensity threshold in the ambient light intensity value sequence, and recording the total number as a fourth numerical value;
acquiring the total number of the ambient light intensity values smaller than the night mode light intensity threshold in the ambient light intensity value sequence, and recording the total number as a fifth value;
if the fourth value is determined to be greater than or equal to a preset first number threshold, or if the fifth value is determined to be greater than or equal to a preset second number threshold, judging the sampling effectiveness detection result as a sampling effectiveness result;
and if the fourth number is smaller than the first number threshold, or if the fifth number is smaller than the second number threshold, judging that the sampling validity detection result is sampling invalid.
In this embodiment, the obtaining of the sampling validity detection result corresponding to the ambient light intensity value sequence may specifically further include: and judging the total number of the ambient light intensity values larger than the daytime mode light intensity threshold value in the ambient light intensity value sequence and the preset first number threshold value, or judging the total number of the ambient light intensity values smaller than the night mode light intensity threshold value in the ambient light intensity value sequence and the preset second number threshold value, so as to determine whether the sampling effectiveness detection result is a sampling effectiveness result.
For example: when the total number of the ambient light intensity values in the ambient light intensity value sequence, which is greater than the daytime mode light intensity threshold, is 8 and the preset first number threshold is 6, it is known that the total number of the ambient light intensity values in the ambient light intensity value sequence, which is greater than the daytime mode light intensity threshold, is greater than the preset first number threshold, and at this time, the vehicle-mounted system can determine that the sampling effectiveness detection result is a sampling effectiveness result.
In one embodiment, after step S120, the method includes:
and if the sampling validity detection result corresponds to the sampling invalidity result, returning to execute the step of continuously acquiring the ambient light intensity value of the preset sampling times in the first preset time to form an ambient light intensity value sequence.
In this embodiment, after the steps of obtaining the brightness value change trend information corresponding to the ambient light intensity value sequence and obtaining the sampling validity detection result corresponding to the ambient light intensity value sequence, if it is determined that the sampling validity detection result corresponds to the sampling invalidity result, the vehicle-to-machine system will control the photosensitive sensor device to continuously execute the step of continuously collecting the ambient light intensity values of the preset sampling times in the first preset time to form the ambient light intensity value sequence, and keep the current mode of the screen unchanged, so that the backlight brightness of the screen cannot be randomly adjusted, thereby improving the stability of the current mode of the screen.
S130, if it is determined that the brightness value change trend corresponds to a continuous descending change trend, and the sampling effectiveness detection result corresponds to a sampling effectiveness result, a preset first backlight dimming strategy and a current backlight mode are obtained, so that the current backlight mode is adjusted to a night mode through the first backlight dimming strategy.
In this embodiment, when the vehicle-mounted system determines that the brightness value change trend information corresponding to the ambient light intensity value sequence corresponds to a continuous descending change trend, and the sampling validity detection result corresponds to a sampling validity result, the vehicle-mounted system correspondingly acquires a first backlight dimming strategy and a current backlight mode preset on a vehicle-mounted screen, and adjusts the current backlight mode to a night mode based on the preset first backlight dimming strategy; preferably, the brightness value corresponding to the ambient light intensity value sequence changes at least five times from light to dark, for example, each ambient light intensity value in the ambient light intensity value sequence is X1, X2, X3, X4, X5, X6, X7, X8, X9 and X10, respectively, where X1, X2, X3, X4, X5, X6, X7, X8, X9 and X10 are all positive integers. When at least any six continuous ambient light intensity values show a descending trend, if X1> X2> X3> X4> X5> X6> X7< X8> X9 and > X10, the vehicle system determines that the mode of vehicle screen matching is a night mode, so that the brightness of the vehicle screen can be automatically adjusted according to the ambient light intensity change.
In an embodiment, the obtaining a preset first backlight dimming policy and a current backlight mode for adjusting the current backlight mode to a night mode according to the first backlight dimming policy includes:
acquiring a backlight brightness reduction value and a first dimming duration corresponding to the first backlight dimming strategy;
acquiring a first target backlight brightness value corresponding to the night mode;
and acquiring a current backlight brightness value corresponding to the current backlight mode, and uniformly changing and adjusting the current backlight brightness value to the first target backlight brightness value in the first dimming duration by taking the backlight brightness reduction value as an adjusting step length so as to switch to the night mode.
In this embodiment, in order to improve the experience of the user on the vehicle screen, the vehicle system sets the backlight brightness of the vehicle screen to be adjusted to the brightness set in the night mode in the preset first dimming time period in a brightness gradual change manner. Specifically, a backlight brightness reduction value and a first dimming duration corresponding to the first backlight dimming strategy are obtained; acquiring a first target backlight brightness value corresponding to the night mode; and acquiring a current backlight brightness value corresponding to the current backlight mode, and uniformly changing and adjusting the current backlight brightness value to the first target backlight brightness value in the first dimming duration by taking the backlight brightness reduction value as an adjusting step length so as to switch to the night mode. The first dimming duration may be manually set by a user, and the first dimming duration is preferably 3s in this embodiment.
Therefore, the method solves the problem that the backlight brightness of the automobile engine screen is too bright due to the change of the ambient light intensity, and avoids discomfort of a user caused by the sudden change of the backlight brightness of the automobile engine screen.
And S140, if the brightness value change trend corresponds to the continuous rising change trend and the sampling effectiveness detection result corresponds to the sampling effectiveness result, acquiring a preset second backlight dimming strategy and a preset current backlight mode, and adjusting the current backlight mode to a daytime mode through the second backlight dimming strategy.
In this embodiment, when the vehicle-mounted system determines that the brightness value change trend information corresponding to the ambient light intensity value sequence corresponds to a continuous rising change trend, and the sampling validity detection result corresponds to a sampling validity result, the vehicle-mounted system correspondingly acquires a second backlight dimming strategy and a current backlight mode preset on a vehicle-mounted screen, and adjusts the current backlight mode to a daytime mode based on the preset second backlight dimming strategy; preferably, the brightness value corresponding to the ambient light intensity value sequence changes from dark to light at least five times continuously, for example, each ambient light intensity value in the ambient light intensity value sequence is X1, X2, X3, X4, X5, X6, X7, X8, X9 and X10, respectively, wherein X1, X2, X3, X4, X5, X6, X7, X8, X9 and X10 are all positive integers. When at least any six continuous ambient light intensity values show a descending trend, if X1< X2< X3< X4< X5< X6> X7< X8> X9 and > X10, the vehicle system determines that the mode of the vehicle screen matching is a daytime mode, so that the brightness of the vehicle screen can be automatically adjusted according to the ambient light intensity change.
In an embodiment, the obtaining the preset second backlight dimming policy and the current backlight mode for adjusting the current backlight mode to the daytime mode according to the second backlight dimming policy includes:
acquiring a backlight brightness increasing value and a second dimming duration corresponding to the second backlight dimming strategy;
acquiring a second target backlight brightness value corresponding to the daytime mode;
and obtaining a current backlight brightness value corresponding to the current backlight mode, and uniformly changing and adjusting the current backlight brightness value to the two target backlight brightness values in the second dimming time length by taking the backlight brightness increasing value as an adjusting step length so as to switch to the daytime mode.
In this embodiment, in order to improve the experience of the user on the vehicle screen, the vehicle system sets the backlight brightness of the vehicle screen to be adjusted to the brightness set in the daytime mode in the preset second dimming time period according to the brightness gradual change mode. Specifically, a backlight brightness increasing value and a second dimming duration corresponding to the second backlight dimming strategy are obtained; acquiring a second target backlight brightness value corresponding to the daytime mode; and obtaining a current backlight brightness value corresponding to the current backlight mode, and uniformly changing and adjusting the current backlight brightness value to the two target backlight brightness values in the second dimming time length by taking the backlight brightness increasing value as an adjusting step length so as to switch to the daytime mode. The second dimming duration may be manually set by the user, and the second dimming duration is preferably 1s in this embodiment.
Therefore, the method solves the problem that the backlight brightness of the automobile engine screen is too dark due to the change of the ambient light intensity, and avoids discomfort of a user caused by the sudden change of the backlight brightness of the automobile engine screen.
According to the method, the ambient light intensity values are collected within the preset time to form an ambient light intensity value sequence, and the current backlight mode of the vehicle screen is adjusted to be in a night mode or in a daytime mode according to the brightness value change trend information corresponding to the ambient light intensity value sequence and the sampling effectiveness detection result corresponding to the ambient light intensity value sequence, so that the backlight brightness of the screen can be automatically adjusted to be set in the night mode or the daytime mode according to the ambient light intensity change, and the use experience of a user is improved.
The embodiment of the application also provides a screen backlight brightness adjusting device which is operated in any embodiment for executing the screen backlight brightness adjusting method. Specifically, referring to fig. 2, fig. 2 is a schematic block diagram of a screen backlight brightness adjusting device according to an embodiment of the application.
As shown in fig. 2, the screen backlight brightness adjusting apparatus 100 includes a sampling unit 110, an acquisition unit 120, a night mode adjusting unit 130, and a day mode adjusting unit 140.
The sampling unit 110 is configured to continuously collect the ambient light intensity values of the preset sampling times in a first preset time, so as to form an ambient light intensity value sequence.
In this embodiment, a photosensitive sensor device is provided on the vehicle system for detecting the current ambient light intensity. Wherein, the car machine system controls the photosensitive sensor device to collect the ambient light intensity value in real time or periodically. When the vehicle machine system of the vehicle is started, the ambient light intensity values of the preset sampling times can be continuously acquired within the first preset time through the photosensitive sensor device to form an ambient light intensity value sequence, the photosensitive sensor device samples the ambient light intensity every 100ms, and therefore the ambient light intensity value sequence of the preset sampling times is continuously acquired within the first preset time, and the brightness value change trend information corresponding to the ambient light intensity value sequence can be conveniently acquired by the following vehicle machine system.
The first preset time and the preset sampling times can be a time threshold and a sampling times threshold set by a vehicle-mounted system or a time threshold and a sampling times threshold set manually by a user.
In one embodiment, the sampling unit 110 includes:
Acquiring a first time period, a second time period and a third time period which are included in the first preset time;

and the first environment light intensity value subsequence, the second environment light intensity value subsequence and the third environment light intensity value subsequence sequentially form the environment light intensity value sequence.
In this embodiment, since the method for adjusting the brightness of the screen backlight adjusts the brightness of the screen backlight only based on the ambient light intensity value acquired by the photosensitive sensor, the problem that the optimization adjustment of the brightness of the screen backlight is not complete is easy to occur. For example, in the driving process, a user shields natural environment light due to the problems of object placement angles and the like in the vehicle, so that parameters of the photosensitive sensor for collecting the environment light intensity value are inaccurate, and further a screen backlight brightness adjustment error is easy to cause. Thus, in order to improve the accuracy of the screen backlight brightness adjustment, a sub-sequence of ambient light intensity values for a plurality of time periods is acquired within a first preset time.
The first preset time may include a plurality of time periods of the subsequence of the ambient light intensity values, where the plurality of time periods included in the first preset time are not specifically limited.
Preferably, the first time period, the second time period and the third time period included in the first preset time are acquired; and obtaining a first sub-sequence of ambient light intensity values corresponding to the first time period, a second sub-sequence of ambient light intensity values corresponding to the second time period, and a third sub-sequence of ambient light intensity values corresponding to the third time period; and the first environmental light intensity value subsequence, the second environmental light intensity value subsequence and the third environmental light intensity value subsequence sequentially form the environmental light intensity value sequence, so that the vehicle-mounted system can more accurately judge the brightness value change trend information corresponding to the environmental light intensity value sequence based on the environmental light intensity value subsequences of a plurality of time periods.
The obtaining unit 120 is configured to obtain brightness value variation trend information corresponding to the ambient light intensity value sequence, and obtain a sampling effectiveness detection result corresponding to the ambient light intensity value sequence.
In this embodiment, the vehicle-mounted system acquires an ambient light intensity value sequence acquired by the photosensitive sensor device, and determines that a mode of screen backlight brightness matching is a night mode or a daytime mode according to brightness value change trend information corresponding to the ambient light intensity value sequence. The brightness value change trend information corresponding to the environment light intensity value sequence is bright- > dark or dark- > bright. When the brightness value change trend information corresponding to the environment light intensity value sequence is bright- > dark, the mode of screen backlight brightness matching is a night mode; when the brightness value change trend information corresponding to the environment light intensity value sequence is dark- > bright, the screen backlight brightness matching mode is a daytime mode.
In addition, after the vehicle-mounted system determines the mode of the screen matching of the vehicle-mounted system, a sampling effectiveness detection result corresponding to the environment light intensity value sequence is obtained according to the environment light intensity value sequence, so that the vehicle-mounted system adjusts the backlight brightness of the screen to a corresponding daytime mode or night mode according to the matched mode and the sampling effectiveness detection result corresponding to the environment light intensity value sequence.

and if the ratio of the second value to the first value is smaller than the first ratio threshold, or if the ratio of the third value to the first value is smaller than the second ratio threshold, judging that the sampling validity detection result is a sampling invalidity result.
In this embodiment, the obtaining of the sampling validity detection result corresponding to the ambient light intensity value sequence may specifically be performed by: judging the ratio of the total number of the ambient light intensity values which are larger than the daytime mode light intensity threshold value in the ambient light intensity value sequence to the total number of the ambient light intensity values which are included in the ambient light intensity value sequence and the size of a preset first proportional threshold value, or judging the ratio of the total number of the ambient light intensity values which are smaller than the night mode light intensity threshold value in the ambient light intensity value sequence to the total number of the ambient light intensity values which are included in the ambient light intensity value sequence and the size of a preset second proportional threshold value, so as to determine whether the sampling effectiveness detection result is a sampling effectiveness result.
For example: when the total number of the ambient light intensity values included in the ambient light intensity value sequence is 10, the total number of the ambient light intensity values greater than the daytime mode light intensity threshold in the ambient light intensity value sequence is 8, and the preset first ratio threshold is 3/5, it is known that the ratio of the total number of the ambient light intensity values greater than the daytime mode light intensity threshold in the ambient light intensity value sequence to the total number of the ambient light intensity values included in the ambient light intensity value sequence is 4/5 and greater than the preset first ratio threshold is 3/5, and the vehicle-to-vehicle system can determine that the sampling effectiveness detection result is a sampling effectiveness result.

acquiring the total number of the ambient light intensity values smaller than the night mode light intensity threshold in the ambient light intensity value sequence, and recording the total number as a fifth value;
if the fourth value is determined to be greater than or equal to a preset first number threshold, or if the fifth value is determined to be greater than or equal to a preset second number threshold, judging the sampling effectiveness detection result as a sampling effectiveness result;
and if the fourth number is smaller than the first number threshold, or if the fifth number is smaller than the second number threshold, judging that the sampling validity detection result is sampling invalid.
In this embodiment, the obtaining of the sampling validity detection result corresponding to the ambient light intensity value sequence may specifically further include: and judging the total number of the ambient light intensity values larger than the daytime mode light intensity threshold value in the ambient light intensity value sequence and the preset first number threshold value, or judging the total number of the ambient light intensity values smaller than the night mode light intensity threshold value in the ambient light intensity value sequence and the preset second number threshold value, so as to determine whether the sampling effectiveness detection result is a sampling effectiveness result.
For example: when the total number of the ambient light intensity values in the ambient light intensity value sequence, which is greater than the daytime mode light intensity threshold, is 8 and the preset first number threshold is 6, it is known that the total number of the ambient light intensity values in the ambient light intensity value sequence, which is greater than the daytime mode light intensity threshold, is greater than the preset first number threshold, and at this time, the vehicle-mounted system can determine that the sampling effectiveness detection result is a sampling effectiveness result.

When at least any six continuous ambient light intensity values show a descending trend, if X1> X2> X3> X4> X5> X6> X7< X8> X9 and > X10, the vehicle system determines that the mode of vehicle screen matching is a night mode, so that the brightness of the vehicle screen can be automatically adjusted according to the ambient light intensity change.
