Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of vehicle hardware adaptation, and particularly relates to a vehicle hardware automatic adaptation method, a vehicle hardware automatic adaptation device and a computer readable storage medium. BACKGROUND

[0002] In the field of automobile development, production and testing, there is a need for driver program adaptation for a large number of vehicles with different hardware configurations. The existing adaptation method is mainly completed manually by technical personnel based on the device tree technology.

[0003] The device tree is a tree-shaped data structure for describing hardware configuration, which contains information about CPU, physical memory, bus, serial port, port physical layer (Physical, PHY) and other peripheral devices. The operating system can perform syntax analysis on this structure when the vehicle starts, configure the kernel with this structure, and load the corresponding driver program. Generally, the operating system usually describes the system device tree in text form using the DTS (Device Tree Source) file, and then uses the device tree compiler (DTC) to convert the DTS file into a binary DTB file (Binary Device Tree Blob). The Linux kernel parses the DTB file to achieve the driving support of the vehicle platform for the current hardware structure. Therefore, based on the device tree data structure, technical personnel only need to burn the DTS file adapted to the current hardware structure to the specified DTS partition, and then load and parse it by the Linux kernel, so as to achieve the driving support of the vehicle platform for the current hardware structure.

[0004] However, since the burned DTS file can only adapt to the current vehicle hardware, once the components of the vehicle are replaced, a professional burning tool needs to be used to re-burn the vehicle image file or to burn the corresponding DTB image separately. Therefore, this existing manual adaptation method is inefficient and cannot meet the needs of the field of automobile development, production and testing for driver program adaptation for a large number of vehicles with different hardware configurations. These fields urgently need an efficient vehicle hardware adaptation technology for automatically adapting the driver program according to the vehicle hardware, so as to improve the adaptation efficiency of the vehicle hardware.

Although the description of the present invention is presented in conjunction with preferred embodiments, this does not mean that the features of the invention are limited to these embodiments. On the contrary, the purpose of describing the invention in conjunction with embodiments is to cover other options or modifications that may be derived based on the claims of the present invention. To provide a thorough understanding of the invention, many specific details will be included in the following description. The invention may also be implemented without using these details. Furthermore, to avoid confusion or obscuring the focus of the invention, some specific details will be omitted in the description.

[0014] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components.

[0016] It is understood that although terms such as "first," "second," and "third" may be used herein to describe various components, regions, layers, and / or parts, these components, regions, layers, and / or parts should not be limited by these terms, and these terms are only used to distinguish different components, regions, layers, and / or parts. Therefore, the first components, regions, layers, and / or parts discussed below may be referred to as second components, regions, layers, and / or parts without departing from some embodiments of the present invention.

[0017] As described above, the existing adaptation method is to manually burn the DTS file adapted to the current car machine hardware into the DTS partition of the car machine system by the technician, so as to realize the driving support of the car machine platform of the current hardware structure. Once the components of the vehicle are replaced, it is necessary to re-burn the image file of the car machine or separately burn the corresponding DTB image by using professional burning tools. Therefore, the existing manual adaptation method is inefficient and cannot meet the needs of driving program adaptation for a large number of different hardware configurations of vehicles in the field of automobile development, production and testing.

[0018] In order to overcome the above-mentioned defects existing in the prior art, the present application provides an automatic adaptation method of car machine hardware, an automatic adaptation device of car machine hardware, and a computer readable storage medium, which can automatically adapt the driving program according to the car machine hardware, thereby improving the adaptation efficiency of the car machine hardware.

[0019] In some embodiments, the above-mentioned automatic adaptation method provided by the first aspect of the present application needs to be implemented in cooperation with a specially designed system image file. The system image file can be generated by the flow shown in Figure 1 . Please refer to Figure 1 , Figure 1 The flowchart for generating the system image file of the car machine is shown according to some embodiments of the present application.

[0020] In the embodiment shown in Figure 1 , before developing, producing and testing the vehicle, the technician can determine the configuration schemes of a plurality of different car machine hardware that the car machine system to be developed, produced and tested may involve in the design stage of the system image file. Then, the technician can describe the device tree corresponding to each hardware configuration scheme in the form of text to generate the device tree description file (for example, the above-mentioned DTS file) corresponding to each hardware configuration scheme. Then, the technician can use the device tree compiler (DTC) to respectively convert each device tree description file into binary to generate the adaptation file (for example, the above-mentioned DTB file) corresponding to each hardware configuration scheme.

[0021] In some embodiments, the technician can name each DTB file according to the hardware configuration scheme corresponding to each DTB file, and pack each named DTB file into the system image file (for example, system.img) of the car machine system for use in the above-mentioned automatic adaptation method provided by the first aspect of the present application.

[0022] Those skilled in the art can understand that, although the above embodiment describes the implementer of the generation process of the car machine system image file as a technician, this does not constitute a limitation on the protection scope of the present application. Preferably, in other embodiments, part or all of the steps of the above generation process of the car machine system image file can also be executed by the processor according to the pre-written computer program, so as to further achieve the effect of reducing labor costs.

[0023] In some non-limiting embodiments, the above automatic adaptation method provided by the first aspect of the present application can be implemented by the above automatic adaptation device provided by the second aspect of the present application. Specifically, the above automatic adaptation device can be configured in the car machine system of the vehicle in the form of a hardware device or a software program, and is configured with a corresponding memory and a processor. The memory includes but is not limited to the above computer readable storage medium provided by the third aspect of the present application, and the computer instructions are stored on the computer readable storage medium. The processor is connected to the memory and is configured to execute the computer instructions stored on the memory to implement the above automatic adaptation method provided by the first aspect of the present application.

[0024] Further, for the configuration scheme of the hardware device, the automatic adaptation device can be configured with an independent memory and a processor dedicated to implementing the above automatic adaptation method. For the configuration scheme of the software program, the automatic adaptation device can share the memory and the processor of the car machine system to implement the above automatic adaptation method.

[0025] The working principle of the above automatic adaptation device will be described below in combination with some embodiments of the automatic adaptation method. Those skilled in the art can understand that these automatic adaptation methods are only some non-limiting embodiments provided by the present application, which are intended to clearly show the main idea of the present application and provide some specific schemes for facilitating the public to implement, and do not constitute a limitation on the whole function or the whole working mode of the above automatic adaptation device. Conversely, the above automatic adaptation device is also only a non-limiting embodiment provided by the present application, which does not constitute a limitation on the implementer of the above automatic adaptation method.

[0026] Please refer to Figure 2 , Figure 2 The flowchart of the automatic adaptation method provided by some embodiments of the present application is shown.

[0027] As Figure 2 shown, in some embodiments of the present application, the automatic adaptation device configured in the car machine system can monitor the running state of the car machine system in real time. In response to the vehicle being in the state of power-on, the automatic adaptation device can perform preliminary self-checking on the car machine system to determine whether it has an abnormality. In some embodiments, the automatic adaptation device can determine whether the car machine system has an abnormality by querying whether there is a record of abnormal error in the running log of the car machine system.

[0028] In response to the result of the determination that the car machine system has an abnormality, the automatic adaptation device can further perform self-checking of software and hardware of the car machine system to determine whether the abnormality is caused by the inadaptation of the currently running adaptation file to the car machine hardware. In some embodiments, the automatic adaptation device can send a request to a microcontroller unit (MCU) of the car machine system according to a predetermined communication protocol to obtain the current hardware configuration information of the car machine system. Then, the automatic adaptation device can compare the obtained hardware configuration information with the name of the currently running adaptation file to determine whether the currently running adaptation file is adapted to the car machine hardware of the vehicle. If the currently running adaptation file is adapted to the car machine hardware of the vehicle, the automatic adaptation device can determine that the above-mentioned abnormality is not caused by the inadaptation of the currently running adaptation file to the car machine hardware. On the contrary, if the currently running adaptation file is not adapted to the car machine hardware of the vehicle, the automatic adaptation device can determine that the above-mentioned abnormality is caused by the inadaptation of the currently running adaptation file to the car machine hardware.

[0029] In Figure 2 In the embodiment shown, in response to the result of the determination that the currently running adaptation file is not adapted to the car machine hardware, the automatic adaptation device can further determine whether the system interface of the car machine system can be normally operated. The system interface includes but is not limited to the central control display interface of the vehicle central control display. In response to the result of the determination that the vehicle central control display interface can be normally operated, the automatic adaptation device can display the control interface of the one-key adaptation function and / or the first designated interface of the adaptation file at a preset position of the central control display interface of the vehicle. The control interface of the one-key adaptation function includes but is not limited to a virtual button drawn on the central control display interface. The first designated interface of the adaptation file includes but is not limited to a text input box drawn on the central control display interface.

[0030] In some embodiments, the user can activate the one-key adaptation function of the automatic adaptation device by clicking the virtual button. In response to the virtual button of the one-key adaptation function being clicked and activated, the automatic adaptation device can send a request to the microcontroller unit (MCU) of the car machine system according to a predetermined communication protocol to obtain the current hardware configuration information of the car machine system. Then, the automatic adaptation device can select a DTB image file having a corresponding name from the system image file of the car machine system according to the obtained hardware configuration information, to serve as a second adaptation file adapted to the current car machine hardware. In this way, the above-mentioned automatic adaptation device provided by the present application can completely eliminate human intervention, and automatically adapt the driver program according to the car machine hardware, thereby improving the adaptation efficiency of the car machine hardware.

[0031] In some embodiments, the user can also provide a specified instruction of the adaptation file (e.g., reset-dtbo.sh XXX) to the automatic adaptation device through the text input box to instruct the automatic adaptation device to load the DTB image file with the corresponding name (i.e., XXX) to support the current car machine hardware. Specifically, in response to the specified instruction input by the user through the first specified interface, the automatic adaptation device can parse the specified instruction to obtain the file name information (i.e., XXX) therein. Then, the automatic adaptation device can query and obtain the DTB image file with the corresponding name from the system image file (i.e., the system.img) of the car machine system as the second adaptation file adapted to the current car machine hardware. In this way, the automatic adaptation device provided by the present application can automatically adapt the driver according to the car machine hardware according to the instruction of the user, thereby improving the adaptation efficiency of the car machine hardware.

[0032] As shown in FIG. 7, in some embodiments of the present application, in response to the judgment result that the vehicle central control display interface cannot operate normally, the automatic adaptation device can provide a second specified interface of the adaptation file to the user. The second specified interface can be a communication interface configured in the background of the car machine system. The user can connect the second specified interface by using an external electronic device through wired and / or wireless communication, and input a specified instruction of the adaptation file through the second specified interface. Figure 2

[0033] As described above, in response to the specified instruction input by the user through the second specified interface, the automatic adaptation device can parse the specified instruction to obtain the file name information (i.e., XXX) therein. Then, the automatic adaptation device can query and obtain the DTB image file with the corresponding name from the system image file (i.e., the system.img) of the car machine system as the second adaptation file adapted to the current car machine hardware. In this way, the automatic adaptation device provided by the present application can automatically adapt the driver to improve the adaptation efficiency of the car machine hardware according to the instruction of the user.

[0034] ​Further, in some preferred embodiments, the first specified interface and the second specified interface can also support the automatic adaptation function. Specifically, a user can input a specified instruction (e.g., reset-dtbo.sh auto) indicating the automatic adaptation function through the first specified interface or the second specified interface. In response to the specified instruction input by the user through the first specified interface or the second specified interface, the automatic adaptation device can parse the received specified instruction to obtain the file name information (i.e., auto) therein. Subsequently, the automatic adaptation device can determine that the user needs to activate the automatic adaptation function according to the parsed file name information (i.e., auto), and then send a request to the micro control unit (MCU) of the car machine system according to a predetermined communication protocol to obtain the current hardware configuration information of the car machine system. Further, the automatic adaptation device can filter the DTB image file with the corresponding name from the system image file of the car machine system as the second adaptation file adapted to the current car machine hardware according to the obtained hardware configuration information. In this way, the automatic adaptation device provided by the present application can automatically adapt the driver according to the car machine hardware according to the user's indication, thereby improving the adaptation efficiency of the car machine hardware.

[0035] Further, in some preferred embodiments, in the case that the specified instruction input by the user is incorrect, and the DTB image file stored in the system image file is incomplete, the automatic adaptation device can not be able to query and obtain the DTB image file with the corresponding name from the system image file (i.e., the above-mentioned system.img) of the car machine system. At this time, in response to the result that the system image file does not store the DTB image file with the corresponding name, the automatic adaptation device can also run the automatic adaptation function, send a request to the micro control unit (MCU) of the car machine system according to a predetermined communication protocol to obtain the current hardware configuration information of the car machine system. Subsequently, the automatic adaptation device can filter the DTB image file with the corresponding name from the system image file of the car machine system as the second adaptation file adapted to the current car machine hardware according to the obtained hardware configuration information. In this way, even if the system image file does not store the DTB image file specified by the user, the automatic adaptation device provided by the present application can still automatically adapt the driver according to the car machine hardware, thereby improving the adaptation success rate and efficiency of the car machine hardware.

[0036] As Figure 2As shown, in some embodiments of the present application, after obtaining the second adaptation file adapted to the current hardware of the car machine from the system image file of the car machine system, the automatic adaptation device can automatically burn the obtained second adaptation file to the device tree source code partition of the car machine system, and restart the car machine system to load and parse the second adaptation file. In response to the restart of the car machine system, the car machine system can load its device tree source code partition with the Linux kernel, and parse the newly burned DTB file therein, so as to realize the driving support of the car machine platform of the current hardware structure by using the newly burned DTB file.

[0037] By using the above automatic adaptation method, the developers and testers of the vehicle can freely replace the components of the vehicle for debugging and testing, and the automatic adaptation device automatically selects the adapted DTB file to provide driving support, thereby avoiding the need for the developers and testers to repeatedly burn the DTB file, and improving the efficiency of debugging and testing the car machine system.

[0038] On the other hand, by using the above automatic adaptation method, the production personnel of the vehicle no longer need to select and burn the corresponding DTB file from a large number of configuration files according to the specific model, batch and hardware configuration of the vehicle, which on the one hand avoids the possibility of burning errors, and on the other hand saves the trouble of re-burning the DTB file. Therefore, the above automatic adaptation method can significantly improve the production efficiency of the vehicle production enterprise.
