Example 1
Fig. 1 is a flowchart of a method for controlling the luminance of an in-vehicle screen according to an embodiment of the present invention, where the method is applicable to a situation where the intensity of the light of the external environment varies strongly when the vehicle is running, and the method may be performed by a device for controlling the luminance of the in-vehicle screen, where the device may be implemented by software and/or hardware and is generally integrated on a control device, and in this embodiment, the control device includes but is not limited to: and the vehicle-mounted controller.
As shown in fig. 1, a method for controlling brightness of an in-vehicle screen according to an embodiment of the present invention includes the following steps:
s110, after the automatic adjustment function of the screen brightness is determined to be started, the calculation of the screen brightness level value is completed within the first calculation time.
In this embodiment, whether the vehicle starts the screen brightness automatic adjustment function may be determined in various manners, for example, the vehicle may be determined to start the screen brightness automatic adjustment function after detecting a corresponding instruction, and the corresponding instruction is automatically generated after the user starts the screen brightness automatic adjustment function button.
After the screen brightness automatic adjusting function is started, the brightness of the vehicle-mounted screen can jump between automatic brightness gears along with the change of external environment light.
In this embodiment, after the automatic screen brightness adjusting function is started, in order to avoid frequent or uneven screen brightness changes, detection of external ambient light and calculation of a screen brightness level value may be performed according to a fixed frequency, and for example, may be set to X seconds detection and calculation once, and specific values of X may be set in a customized manner.
Wherein, the first calculation time may be understood as a first X seconds, and completing the calculation of the screen brightness level value in the first X seconds may include: the brightness of the external environment light is detected once in the first X seconds, and the screen brightness level is determined according to the brightness of the external environment light. The method for detecting the external environment brightness is various, and optionally, the external environment brightness can be determined by shooting an external environment image through a vehicle-mounted camera and detecting the brightness of the external environment image; preferably, the brightness of the external environment light can be directly detected through the light sensor, and the brightness value obtained by the detection mode is more accurate.
S120, in the second calculation time, the screen brightness grade value is calculated according to the first calculation time to switch the screen brightness grade step by step, the calculation of the screen brightness grade value is completed again, and in the third calculation time, the screen brightness grade value is switched according to the recalculated screen brightness grade value.
Wherein the end time of the first calculation time is earlier than the start time of the second calculation time, and the end time of the second calculation time is earlier than the start time of the third calculation time.
Note that, the time values of the first calculation time, the second calculation time, and the third calculation time may be the same or different, and are not particularly limited herein.
The second calculation time may be understood as the second X seconds, and the third calculation time may be understood as the third X seconds.
In this embodiment, if the screen brightness level value calculated in the first calculation time is 5, but the current screen brightness level is 2, the screen brightness levels need to be switched step by step according to the order from 2 to 3 to 4 to 5, and the switching between each level needs to be completed in X seconds, so the switching from 2 to 5 needs to be completed in 3X seconds (i.e. within 3X seconds). Meanwhile, the calculation of the screen brightness level value needs to be completed again within X seconds when the screen brightness level is switched from 2 to 3, the latest screen brightness level value is obtained, the current screen brightness level is adjusted from 3 to the latest screen brightness level value step by step in the next X seconds, namely, the third calculation time is started, and the like.
In this embodiment, the screen brightness level switching is a step-by-step switching, instead of a jump (instead of directly jumping from level 1 to level 4), and in the step-by-step switching process, the screen brightness level value is also detected and calculated at a fixed frequency, and a new screen brightness level is matched according to the latest calculated screen brightness level value, and the screen brightness level switching is performed according to the latest screen brightness level.
It should be noted that the process of completing the calculation of the brightness level value of the screen within each X seconds is the same, and will not be described here.
The first embodiment of the invention provides a method for controlling the brightness of an in-vehicle screen, which comprises the steps of firstly, after determining that the vehicle starts an automatic screen brightness adjusting function, completing calculation of a screen brightness grade value in a first calculation time; and then in the second calculation time, the screen brightness grade value is calculated according to the first calculation time to switch the screen brightness grade step by step, the calculation of the screen brightness grade value is completed again, and in the third calculation time, the screen brightness grade value is switched according to the recalculated screen brightness grade value. The method can calculate the screen brightness level value in real time, and gradually complete screen brightness gear switching according to the calculated screen brightness level value, so that jump of the screen brightness is effectively avoided, and the adjusted screen brightness can be accurately adapted to the external environment.
On the basis of the above embodiments, modified embodiments of the above embodiments are proposed, and it is to be noted here that only the differences from the above embodiments are described in the modified embodiments for the sake of brevity of description.
In one embodiment, the calculating process of the screen brightness level value includes:
detecting the brightness value of external environment light through the light sensor of the whole vehicle;
matching the brightness value of the external environment light to a corresponding screen brightness level value through a preset table;
the preset table includes the corresponding relation of the brightness value of the external environment light, the screen brightness grade value and the pulse width modulation value (Pulse Width Modulation, PWM).
In the present embodiment, the luminance value of the external ambient light may be detected by the light sensors mounted on the vehicle, the number and mounting positions of the light sensors are not particularly limited herein, and various cases may be included, and are not listed here.
The light sensor is a high-performance sensor developed by utilizing a laser technology and mainly comprises a photosensitive element, and is mainly divided into four types of an ambient light sensor, an infrared light sensor, a solar light sensor and an ultraviolet light sensor.
The preset table can be a preset screen brightness level comparison table, and the brightness value of the external environment light can be matched with the screen brightness level value according to the corresponding relation in the table.
Table 1 shows a screen brightness level comparison table according to an embodiment of the present invention, wherein the corresponding screen brightness level value of the ambient light brightness value is 1 and the corresponding PWM value is 9% in the interval 0-250 as shown in Table 1; the corresponding screen brightness level value of the ambient light brightness value in the 251-3000 interval is 2, and the corresponding PWM value is 13%; the corresponding screen brightness level value of the ambient light brightness value in the 3001-10000 interval is 3, and the corresponding PWM value is 27%; the corresponding screen brightness level value of the ambient light brightness value in the interval 10001-90000 is 4, and the corresponding PWM value is 57%; the ambient light brightness value corresponds to a screen brightness level value of 5 and a corresponding PWM value of 83% in the interval 90001-1371071.

Fig. 2 is a flow chart of a method for controlling the brightness of an in-vehicle screen according to a second embodiment of the present invention, where the second embodiment is optimized based on the above embodiments. For details not yet described in detail in this embodiment, refer to embodiment one.
As shown in fig. 2, a method for controlling the brightness of an in-vehicle screen according to a second embodiment of the present invention includes the following steps:
s210, after the automatic adjustment function of the screen brightness is determined to be started, the calculation of the screen brightness level value is completed within the first calculation time.
And S220, if the gear of the current screen brightness is A and the screen brightness grade value calculated in the first calculation time is B, switching from the screen brightness gear A to the screen brightness gear B is completed step by step in B-A calculation times.
Wherein the value represented by B is larger than the value represented by A.
For example, if the current screen brightness level is 1 and the calculated screen brightness level value is 5 in the first X seconds, it is necessary to complete the shift from level 1 to level 2 to level 3 to level 4 to level 5 in the next 4X seconds. Specifically, the shift from gear 1 to gear 2 is completed within 1X seconds, the shift from gear 1 to gear 2 to gear 3 is completed within 2X seconds, and the shift from gear 1 to gear 2 to gear 3 to gear 4 is completed within 3X seconds.
Further, if the screen brightness shift positions a+1 and B are the same, the switching from the screen brightness shift position a to the screen brightness shift position B is completed within the second calculation time.
For example, if the current screen brightness level is 1 and the calculated screen brightness level value is 2 in the first X seconds, the switching from the screen brightness level 1 to the screen brightness level 2 is completed in the second X seconds.
S230, switching from the screen brightness gear A to the screen brightness gear A+1 is completed in the second calculation time, and if any one of the screen brightness grade values A+2 to B is recalculated in the second calculation time, switching from the screen brightness gear A+1 to the screen brightness gear A+2 is completed in the third calculation time.
For example, the screen brightness shift from the shift position 1 to the shift position 2 is completed in the second X seconds, at the same time, the current screen brightness level value needs to be recalculated in the second X seconds, if the recalculated screen brightness level value is any one of the values from 3 to 5, the shift from the shift position 2 to the shift position 3 to the shift position 4 to the shift position 5 can be continuously completed, the screen brightness shift from the shift position 2 to the shift position 3 is continuously switched in the next X seconds, namely, the third X seconds according to the switching sequence, and the screen brightness level value is recalculated in the third X seconds at the same time.
Further, if the screen brightness shift positions a+2 and B are the same, the switching from the screen brightness shift position a+1 to the screen brightness shift position B is completed within the third calculation time.
The screen brightness shift is switched from the shift a=1 to the shift a+1=2 in the second X seconds, meanwhile, the current screen brightness level value needs to be recalculated in the second X seconds, and if the current screen brightness level value is a+2=3 and b=3, the screen brightness shift is continuously switched from the shift 2 to the shift 3 in the third X seconds.
The method for controlling the brightness of the screen in the vehicle provided by the second embodiment of the invention embodies a gear switching mode corresponding to the recalculation in the second calculation time when the brightness level value of the screen is any one of the values from A+2 to B.
Example III
Fig. 3 is a flowchart of a method for controlling the brightness of an in-vehicle screen according to a third embodiment of the present invention, where the third embodiment is optimized based on the first embodiment. For details not yet described in detail in this embodiment, refer to embodiment one.
As shown in fig. 3, a method for controlling the brightness of an in-vehicle screen according to a third embodiment of the present invention includes the following steps:
s310, after the automatic adjustment function of the screen brightness is determined to be started, the calculation of the screen brightness level value is completed within the first calculation time.
S320, if the level of the current screen brightness is A and the screen brightness level value obtained by calculation in the first calculation time is B, switching from the screen brightness level A to the screen brightness level B is completed step by step in B-A calculation times.
Wherein the value represented by B is larger than the value represented by A.
For example, if the current screen brightness level is 1 and the calculated screen brightness level value is 5 in the first X seconds, it is necessary to complete the shift from level 1 to level 2 to level 3 to level 4 to level 5 in the next 4X seconds. Specifically, the shift from gear 1 to gear 2 is completed within 1X seconds, the shift from gear 1 to gear 2 to gear 3 is completed within 2X seconds, and the shift from gear 1 to gear 2 to gear 3 to gear 4 is completed within 3X seconds.
S330, switching from the screen brightness gear A to the screen brightness gear A+1 is completed in the second calculation time, and if the screen brightness grade value is calculated again to be A+1 in the second calculation time, the screen brightness gear is maintained at the screen brightness gear A+1 in the third calculation time.
For example, the screen brightness shift from the shift 1 to the shift 2 is completed in the second X seconds, and at the same time, the current screen brightness level value needs to be recalculated in the second X seconds, if the recalculated screen brightness level value is 2, the screen brightness shift that is not completed needs to be discarded, the screen brightness shift is maintained in the shift 2 in the third X seconds, and at the same time, the screen brightness level value needs to be recalculated in the third X seconds.
The method for controlling the brightness of the screen in the vehicle provided by the third embodiment of the invention embodies a gear switching mode corresponding to the screen brightness level value A+1 obtained by recalculating in the second calculation time.
Example IV

And S420, if the gear of the current screen brightness is A and the screen brightness grade value calculated in the first calculation time is B, switching from the screen brightness gear A to the screen brightness gear B is completed step by step in B-A calculation times.
Wherein the value represented by B is larger than the value represented by A.
For example, if the current screen brightness level is 1 and the calculated screen brightness level value is 5 in the first X seconds, it is necessary to complete the shift from level 1 to level 2 to level 3 to level 4 to level 5 in the next 4X seconds. Specifically, the shift from gear 1 to gear 2 is completed within 1X seconds, the shift from gear 1 to gear 2 to gear 3 is completed within 2X seconds, and the shift from gear 1 to gear 2 to gear 3 to gear 4 is completed within 3X seconds.
S430, switching from the screen brightness gear A to the screen brightness gear A+1 is completed in the second calculation time, and if the screen brightness grade value is calculated again in the second calculation time to be A, switching from the screen brightness gear A+1 to the screen brightness gear A is completed in the third calculation time.
For example, the screen brightness shift is completed from the shift 1 to the shift 2 in the second X seconds, at the same time, the current screen brightness level value needs to be recalculated in the second X seconds, if the recalculated screen brightness level value is 1, the screen brightness shift that is not completed needs to be discarded, the screen brightness shift is switched to the shift 1 in the third X seconds, and at the same time, the screen brightness level value needs to be recalculated in the third X seconds.
The fourth embodiment of the invention provides a method for controlling the brightness of an in-vehicle screen, which embodies a gear switching mode corresponding to the recalculation of the brightness level value of the screen in the second calculation time to be A.
The embodiment of the invention provides several specific implementation modes based on the technical scheme of each embodiment.
As a specific implementation manner of the present embodiment, fig. 5 is a flowchart of a method for controlling luminance of an in-vehicle screen according to an exemplary embodiment of the present invention, where, as shown in fig. 5, the method includes the following steps:
