Example 1

Fig. 1 is a flowchart of a method for starting a central control panel of an automobile according to an embodiment of the present invention.

With the development of automobile technology, a central control screen of an automobile is arranged on most automobiles, so that a driver can conveniently perform driving control operation on the automobile through the central control screen of the automobile and obtain driving assistance. The central control screen of the automobile has become the key point of the intelligent development of the whole automobile control, along with the continuous integration of functions on the central control screen, the central control screen can display the display contents of various applications, but in the stage of preparing to start the automobile, the display contents of part of the central control screen are not very strong in assistance to a driver, and only part of functions, such as displaying images around an automobile body to realize safe and convenient starting of the automobile, are necessary in the stage of preparing to start the automobile according to the driving habit of a general driving automobile.

According to the method and the device for controlling the automobile central control screen, through the characteristic that a large number of functions in the central control screen are not needed in the automobile starting stage, the speed of starting the central control screen of the automobile is accelerated, so that a driver can use the central control screen in the shortest time to assist in completing driving of the automobile.

The method can be performed by a starting device for a vehicle center screen, which can be implemented in hardware and/or software.

As shown in fig. 1, the present embodiment may include the following steps:

s110, loading a compressed kernel image in the process of starting a central control screen of the automobile, and decompressing the compressed kernel image to obtain the kernel image;

s120, starting a kernel of the central control screen based on the kernel image, wherein one or more necessary drivers are included in the kernel.

and reading the decompressed kernel image from the hardware decompression unit.

Optionally, before loading the compressed kernel image, the method further comprises the steps of:

and starting a CPU of the central control screen, wherein the CPU is provided with a plurality of CPUs.

Optionally, starting the kernel of the central control screen based on the kernel mirror image comprises the following steps:

if there are multiple necessary drivers, multiple CPUs are used to load the necessary drivers in parallel.

Optionally, after the kernel of the central control screen is started based on the kernel image, the method further comprises the following steps:

loading a root file system;

and running a startup script, wherein if a plurality of independent startup scripts exist in the startup script, a plurality of CPUs are adopted to run the startup script in parallel.

Optionally, after running the boot script in the background, the method further comprises the steps of:

starting a first application program;

one or more driving units are loaded, and the driving units are generated after compiling unnecessary driving programs.

when starting the kernel, identifying key log data;

and deleting other log data except the key log data.

In this embodiment, in the process of starting the central control panel of the automobile, reference may be made to a flowchart of starting the central control panel of the automobile in fig. 2, and in step S210, the central control panel may be started by powering up, and after powering up, the CPU of the central control panel is started according to step S220. The kernel images may then be loaded according to step S230, and specifically, the kernel images may be pulled from a repository served by a remote image repository, where one image repository may include multiple images, a name and/or a tag of the kernel image to be pulled may be predetermined, and the kernel image to be loaded may be located in the repository by the name and/or the tag.

After the kernel image is pulled, in order to reduce the size of the kernel image, the kernel image obtained by pulling may be compressed in a manner of compressing the kernel image, and then the compressed kernel image is generated, as in step S240 in fig. 2, and the kernel image is compressed to obtain a compressed kernel image. Compared with the uncompressed kernel image, the space occupied by the compressed kernel image is reduced, and particularly, the space occupied by the compressed kernel image can be reduced by about 40%. The time consumed in the subsequent reading is also greatly reduced, so as to achieve the aim of accelerating the opening of the central control screen.

When the method is implemented, the compressed kernel image obtained after compression can be burnt on a memory of the device when the kernel image is compressed, and specifically, the compressed kernel image can be stored in an EMMC (EMMC, embedded Multi Media Card, embedded multimedia controller) on a circuit board.

The compressed kernel image may be loaded from the memory storing the compressed kernel image, and then decompressed according to step S250 in fig. 2 to obtain the kernel image.

When the compressed kernel image is decompressed, the compressed kernel image can be input to a hardware decompression unit, and the compressed kernel image is decompressed through the hardware decompression unit. With a hardware decompression unit, the time of decompression can be reduced compared to decompression with CPU software. In this embodiment, a compression and decompression algorithm supporting hardware acceleration may be adopted, and after the hardware decompression unit is started for acceleration, the time for decompressing the compressed kernel image may be greatly reduced, and in particular, the time for decompressing may be reduced by 50%.

In addition, the hardware decompression unit may be a set of multistage registers, where in decompression, in order to increase the access speed, the storage capacity of the first stage registers may be smaller, and the compressed kernel image may be divided into several parts, where the size of each divided part of compressed kernel image is the same as the size of the storage capacity of the first stage registers, or the size of each divided part of compressed kernel image is slightly smaller than the size of the first stage registers.

When one compressed kernel image is input into the register of the first stage, the register of the first stage can start decompression to obtain the kernel image corresponding to the compressed kernel image, and then the obtained kernel image is transmitted to a memory of the next stage for storage, and at the moment, the memory of the first stage is empty, and the register of the first stage can continuously receive another compressed kernel image and continue decompression. After decompression of all the segmented compressed kernel images is completed by the memory of the first stage, the complete decompressed kernel images can be read from the memory of the next stage corresponding to the memory of the first stage.

In this embodiment, the CPU of the central control panel is started up for step S220 in fig. 2, where there may be a plurality of CPUs. Specifically, the processor on the central control screen is provided with a plurality of CPU cores, and when the processor on the central control screen is started, the plurality of CPU cores correspondingly start to run together. Because the inner core of the central control screen comprises one or more necessary driving programs, the necessary driving programs correspond to the content, the functions and the like which need to be displayed by the central control screen in a matched mode when a driver starts the automobile, for example, images around the automobile are displayed, the driver is matched with the automobile to drive the automobile away from a parking space, for example, the distance between the periphery of the automobile and an obstacle is displayed, and the automobile is prevented from being scratched and the like in the process of driving the automobile away from the parking space.

For the step S260 in fig. 2, when there are multiple necessary drivers, multiple CPUs may be used to load the necessary drivers in parallel, and each different CPU is loaded corresponding to a different necessary driver, and memory management is performed. The mode of loading necessary driving programs by a plurality of CPUs in parallel can fully utilize the advantages of the central control screen adopting the multi-core CPU. For example, there are currently three necessary drivers A, B, C that are not related to each other, and A, B, C can be loaded by different CPUs at the same time. In the current mode, most processors are multi-core, but only one CPU core is always used when the core is started, namely, the processor needs to process A, process B and process C. Compared with the mode of using only one CPU core, the mode of parallel processing of a plurality of CPUs provided by the embodiment can reduce the starting time, and particularly, the starting time of the cores of the plurality of CPUs can be shortened by 2-3 seconds when the cores of the plurality of CPUs are operated simultaneously.

After the kernel of the central control screen is started based on the kernel image, step S270 in fig. 2 is also required to load a root file system, which is a file system that is the first file system mounted when the kernel is started. The system boot startup procedure loads some basic initialization scripts and services into the memory to run after the root file system is mounted, wherein the system boot startup procedure includes a startup script, i.e. step S280 in fig. 2 runs the startup script, and if a plurality of independent startup scripts exist in the startup script, a plurality of CPUs are adopted to run the startup script in parallel.

Specifically, when a plurality of mutually independent startup scripts exist, a mode of script background operation can be adopted when the startup scripts are operated, and a plurality of CPUs are adopted, so that the parallel operation of the startup scripts is realized, and the parallel operation can reduce the startup time because the processor is a multi-core processor. Compared with a mode of running the startup script one by one when running the startup script, the parallel running mode in the embodiment can enable a plurality of processors to run a plurality of scripts at the same time, and reduce the time for running the startup script.

After the boot script is run in the background, step S290 in fig. 2 may be performed to start the first application program and load one or more driving units, where the driving units are units generated by compiling unnecessary driving programs, and the driving units are compiled in advance according to predetermined unnecessary driving programs.

For functions other than the auxiliary functions that the driver must acquire through the central control screen when the vehicle is just started, unnecessary drivers, such as ethernet, USB, etc., may be corresponded. The unnecessary drivers are compiled into the driver units, and the driver units corresponding to the unnecessary drivers may be loaded after the first application program is started. Compared with the current method, all driving units are initialized in the process of loading the kernel, and the loading time of part of driving units, such as the Ethernet PHY chip, is long, and the function provided by part of driving is not needed by the first application program, therefore, the method provided by the embodiment can compile unnecessary driving programs into driving units, and load the driving units in a delayed way, so that the starting speed can be increased.

The driving unit is compiled in advance, compared with the fact that compiling into the mirror image causes the starting kernel to consume longer time, compiling into the driving unit does not consume the starting time of the starting kernel, and the driving unit can be loaded after the kernel is started, so that the starting time of the kernel is shortened, and the first application program can be started faster.

In one embodiment, when the kernel of the central control screen is started based on the kernel image, key log data can be identified first when the kernel is started, wherein when the key log data is identified, the log data capable of indicating the reason of the system start failure can be identified, and because the log data is only useful when the fault is analyzed, other logs except for the reason of the system start failure can be redundant, and therefore, the other log data except for the key log data is deleted, so that the starting time can be reduced. Compared with the mode of opening the kernel log function without deleting redundant log data, the mode provided by the embodiment can shorten the kernel starting time, and particularly, the kernel starting time can be shortened by about 3-5 seconds.

In the method, in the process of starting the central control screen of the automobile, the compressed kernel mirror image is loaded, so that occupation of a mirror image space can be reduced, the compressed kernel mirror image is decompressed to obtain the kernel mirror image, the central control screen is started based on the kernel of the kernel mirror image, one or more necessary driving programs are included in the kernel, only the necessary driving programs are started, starting time required by starting the unnecessary driving programs is shortened, starting time of the central control screen of the automobile is obviously shortened, and use requirements of a driver on the central control screen of the automobile can be met.
