Detailed Description
Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
When a vehicle-mounted system (such as an Android vehicle-mounted system) is started, a BootLoader is started first. The BootLoader is a program which runs before the operating system runs, and can initialize hardware equipment and establish a memory space mapping chart, so that the software and hardware environment of the system is brought to a proper state, preparation is made for running the operating system, then the Linux/Android program is entered until the vehicle-mounted system is started, and the operating interface of the vehicle-mounted system is displayed. In the BootLoader phase, the program reads the backlight brightness value set by default in the system. The inventor finds that if the default backlight brightness value is different from the backlight brightness value set in the last startup, the brightness displayed by a startup identifier (logo) on a screen during startup is inconsistent with the brightness value displayed in the startup animation playing process, so that the screen brightness during startup is flickering, and the user experience is poor.
In order to solve the above technical problem, an embodiment of the present invention provides a method for setting backlight brightness when a vehicle-mounted system is powered on. Fig. 1 is a flowchart illustrating a method for setting backlight brightness when a vehicle-mounted system is powered on according to an embodiment of the invention. Referring to fig. 1, the method may include at least the following steps S102 to S106.
And step S102, when the vehicle-mounted system is started, starting a boot loader, and displaying a starting identifier on a screen.
And step S104, reading the backlight brightness value which is saved when the vehicle-mounted system is used and is modified last time as the current backlight brightness value, and setting the current backlight brightness value as the backlight brightness value of the starting-up identifier.
And step S106, after the loading of the boot loader is finished, playing the boot animation under the current backlight brightness value until the boot animation is finished.
In the method for setting the backlight brightness of the vehicle-mounted system during startup provided by the embodiment of the invention, the backlight brightness value which is saved when the vehicle-mounted system is used before the current time is read in the starting process of the boot loader, the modified backlight brightness value is set as the backlight brightness value of the startup identifier (logo), and the startup animation is played under the backlight brightness value after the boot loader is loaded, so that the brightness of the startup logo is consistent with the brightness of the startup animation during playing, the conditions that the screen brightness is inconspicuous and obviously changed during startup are avoided, the current backlight brightness is consistent with the comfortable brightness value used by the user at the previous time, and the user experience of the user during automobile use is improved.
In step S102, when the vehicle-mounted system is started, the vehicle-mounted system first starts a BootLoader, and the BootLoader loads and displays the boot logo on the screen. The screen is typically provided on a center console.
In step S104, in the BootLoader loading process, the last modified backlight brightness value stored when the vehicle-mounted system is used before this time may be read in a local access (for example, access to a local storage device) or a remote access (for example, access to a remote server).
In step S106, after the BootLoader finishes loading the boot loader, the system enters an operating system (e.g., Linux/Android program), and at this time, the system keeps the current backlight brightness value and the backlight brightness value of the boot logo unchanged, and starts playing the boot animation at the current backlight brightness value until the boot animation is played, so as to ensure that the backlight brightness value of the boot logo is consistent with the backlight brightness value during the process of starting playing the boot animation and playing the boot animation.
In an alternative embodiment, after step S102, a step of determining whether the vehicle-mounted system is turned on for the first time may also be performed. If the boot is not the first time, step S104 is executed. If the starting is carried out for the first time, the backlight brightness default value set by the vehicle-mounted system is set as the current backlight brightness value, the backlight brightness default value is further set as the backlight brightness value of the starting logo, and the starting animation is played under the backlight brightness default value.
In an alternative embodiment, after step S106, the following steps may also be performed:
monitoring whether the backlight brightness value of a screen is modified in the using process of the vehicle-mounted system;
if yes, the modified backlight brightness value is stored for the next time the vehicle-mounted system is started.
In one embodiment, the backlight brightness value of the screen may be modified by the user during use of the in-vehicle system by, for example, key operation, voice command, etc. When a user modifies the backlight brightness value of the screen, the operation is generally performed on the Home interface of the system. Therefore, after the startup animation is played, the Home main interface of the vehicle-mounted system can be displayed under the current backlight brightness value, and the operation of the user on the Home main interface is monitored, so that whether the user modifies the backlight brightness value of the screen or not is judged.
In another alternative embodiment, the backlight brightness value of the screen may also be adaptively modified by the on-board system during its use according to the ambient light changes.
In a preferred embodiment, when it is monitored that the backlight brightness value of the screen is modified during use of the in-vehicle system, the modified backlight brightness value is updated and stored in the non-volatile memory. Accordingly, in step S104, the last modified backlight luminance value saved when the in-vehicle system was used before that is read from the nonvolatile memory. The nonvolatile memory mentioned herein refers to all storage devices that do not lose stored data after power is turned off, such as a hard disk, an eMMC (Embedded multimedia Card), a flash memory, and the like.
In addition, after the vehicle-mounted system is started, if the backlight brightness value of the screen is not monitored to be modified in the using process of the vehicle-mounted system, the backlight brightness value stored in the nonvolatile memory is not updated. And ending the process until the vehicle-mounted system is shut down.
In the above, various implementation manners of each link of the embodiment shown in fig. 1 are introduced, and the implementation process of the setting method of the backlight brightness when the vehicle-mounted system is turned on according to the present invention will be described in detail through a specific embodiment.
Fig. 2 is a flowchart illustrating a method for setting backlight brightness when a vehicle-mounted system is turned on according to an embodiment of the invention. In this embodiment, the vehicle-mounted system is an Android vehicle-mounted system. The flow steps of this embodiment will be specifically described with reference to fig. 2.
And step S2.1, starting BootLoader.
When a user starts the vehicle-mounted system, the vehicle-mounted system starts a BootLoader bootstrap program at first.
And S2.2, loading and displaying the boot logo by the BootLoader.
And S2.3, judging whether the starting is started for the first time, if not, entering the step S2.4, and if so, entering the step S2.5.
And S2.4, reading the backlight brightness value modified last time from the nonvolatile memory as the current backlight brightness value, and setting the current backlight brightness value as the backlight brightness value of the startup logo.
And S2.5, setting the current backlight brightness value and the backlight brightness value of the startup logo as backlight brightness default values.
And S2.6, keeping the current backlight brightness value and the backlight brightness value of the startup logo.
After the BootLoader finishes loading the bootstrap program, the system enters a Linux/Android system, and the current backlight brightness value and the backlight brightness value of the startup logo are kept unchanged by the system at the moment.
And S2.7, starting to play the boot animation under the current backlight brightness value until the boot animation is played.
Because the backlight brightness value of the startup logo and the backlight brightness value of the startup animation which starts to be played are not changed, the condition that the screen brightness is obviously changed can not occur.
And S2.8, displaying the Home main interface of the vehicle-mounted system by using the current backlight brightness value.
Step S2.9, it is monitored whether the backlight brightness value of the screen is modified.
After the vehicle-mounted system is started, a user may adjust the brightness of the screen in time according to the change of the light of the current surrounding environment during the use of the vehicle-mounted system. Therefore, after the Home main interface is displayed, the operation of the user on the Home main interface is monitored, and whether the backlight brightness value of the screen is modified by the user is judged. If the user has adjusted the backlight brightness of the screen, step S2.10 is entered. After the car machine system is started, if the user does not adjust the backlight brightness of the screen and the screen brightness does not change, the backlight brightness value stored in the nonvolatile memory does not need to be updated, and the step S2.12 is directly performed.
And S2.10, updating and storing the modified backlight brightness value in the nonvolatile memory when the user adjusts the screen backlight brightness, and using the backlight brightness value for the next startup of the vehicle-mounted system.
And S2.11, modifying the backlight brightness of the screen according to the modification operation of the user.
And S2.12, shutting down the vehicle-mounted system, and ending the process.
Wherein, the steps S2.1 to S2.5 are executed in the BootLoader boot stage, and the steps S2.6 to S2.12 are executed in the Linux/Android system.
Of course, if the backlight brightness value of the screen is modified a plurality of times during use of the in-vehicle system, steps S2.9 to S2.11 may be repeated to update and store the latest modified backlight brightness value.
The embodiment can ensure that the brightness of the startup logo is consistent with the brightness of the startup animation during playing, avoid the conditions of flickering and obvious change of the screen brightness during startup, and can store the backlight brightness value modified by the user for use during next startup of the vehicle-mounted system, thereby improving the user experience of the user during use of the vehicle.
