[0003] However, in the actual use of the user, it is found that if the screen backlight brightness set before the vehicle-mounted system is turned off is different from the default backlight brightness value set in the vehicle-mounted system’s BootLoader, the brightness of the boot logo (logo) will be different when the vehicle-mounted system is turned on next time. The brightness is inconsistent with the brightness when the boot animation is playing, resulting in a significant change in screen brightness
If the user needs to turn on / off the in-vehicle system frequently every day, it will lead to poor user experience

Embodiment Construction
[0044] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although 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 by the embodiments set forth herein. Rather, these embodiments are provided for more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.
[0045] When the vehicle-mounted system (such as the Android vehicle-mounted system) is turned on, the bootloader program BootLoader must be started at first. BootLoader is a program that runs before the operating system runs. It can initialize hardware devices and create a memory space map, so as to bring the system's hardware and software environment to a suitable state, prepare for running the operating system, and then enter Linu...

The invention provides a method and a device for setting the brightness of a backlight when a vehicle-mounted system is turned on. The method comprises: when starting the vehicle-mounted system, starting a boot loader, and displaying a boot logo on the screen; reading the previously modified backlight brightness value saved when using the vehicle-mounted system as the current backlight brightness value, and storing the The current backlight brightness value is set as the backlight brightness value of the boot logo; after the boot loader is loaded, the boot animation is played at the current backlight brightness value until the boot animation ends. The solution provided by the present invention can keep the brightness of the startup logo consistent with the brightness when the startup animation is played, avoiding the situation that the brightness of the screen is flickering and obviously changing during startup, and the brightness of the current backlight is more comfortable than that used by the user last time. The brightness value of the car is consistent, which improves the user experience of the user when using the car.
Description
technical field [0001] The invention relates to the technical field of vehicle systems, in particular to a method and device for setting backlight brightness when the vehicle system is turned on. Background technique [0002] With the rapid improvement of people's quality of life, more and more users cannot do without cars every day. Today's cars are becoming more and more intelligent, thanks to the increasing sophistication and popularity of in-vehicle intelligent systems. The on-board intelligent system can provide users with a variety of functions such as navigation, driving control, infotainment, telephone communication, etc., and bring users a brand-new car experience, and has become the standard configuration of most models. [0003] However, in the actual use of the user, it is found that if the screen backlight brightness set before the vehicle-mounted system is turned off is different from the default backlight brightness value set in the vehicle-mounted system’s B...
