[0002] As the number of car cockpit functions increases, the operating system of the cockpit host is becoming more and more complex. Currently, the mainstream cockpit host operating system all uses the Android system. With the popularization of the Android operating system in cockpit hosts, the problem of system fragmentation has gradually emerged, becoming one of the important factors restricting its further development. In order to provide more personalized services or optimize specific functions, car manufacturers will conduct secondary development on the basis of the native Android system and launch their own UI interface and special applications. Although these changes have enriched user choices, they have also further increased the degree of system fragmentation.

[0003] However, when the fragmented files in the cockpit host's operating system accumulate to a certain extent, the cockpit host's operating system will be unable to start, seriously affecting the use of the vehicle. Moreover, after the cockpit host's operating system cannot start, the traditional solution of transporting the faulty vehicle to an after-sales service store and replacing the host or specific equipment is also time-consuming and laborious.

[0022] The following describes the embodiments of the present invention by specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict.

[0023] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present invention, and thus the drawings only show components related to the present invention rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed arbitrarily, and the component layout may also be more complicated.

[0024] In the following description, numerous details are discussed to provide a more thorough explanation of the embodiments of the present invention. However, it is obvious to those skilled in the art that the embodiments of the present invention can be implemented without these specific details. In other embodiments, well-known structures and devices are shown in the form of block diagrams rather than in detail to avoid making the embodiments of the present invention difficult to understand.

[0025] Lin (Local Interconnect Network) bus is a low-cost serial communication network defined for automotive distributed electronic systems. It is a supplement to other automotive multi-channel networks such as the Controller Area Network (CAN) and is suitable for applications that do not have high requirements on network bandwidth, performance or fault tolerance.

[0026] In computer networks, IPCP (Internet Protocol Control Protocol) is a network control protocol used to establish and configure the Internet Protocol on a point-to-point protocol connection. IPCP is responsible for configuring, enabling, and disabling IP protocol modules at both ends of a point-to-point connection. IPCP uses the same message exchange mechanism as the link control protocol. IPCP messages will not be exchanged until PPP reaches the network layer protocol stage, and any IPCP messages received before this stage should be silently discarded.

[0027] See also Figure 1 The present invention provides a method for clearing fragmented files of a cockpit host, comprising:

[0028] Step S10: Obtain physical key instructions;

[0029] Step S20: converting the physical key command into a protocol command;

[0030] Step S30: Clean up the fragmented files according to the protocol instructions;

[0031] Step S40: After the fragmented files are cleaned up, the cockpit host system is restarted.

[0032] Through the above steps, it is not difficult to find that in the process of clearing fragmented files in the system of the cockpit host, the user can press the corresponding physical button in the cockpit host to obtain the physical button instruction for clearing the fragmented files of the cockpit host. According to the physical button instruction, it can be further converted into a protocol instruction, and the fragmented files are controlled by the protocol instruction for cleaning. And after the cleaning is completed, the cockpit host system is restarted. Through the above content, the cleaning work can be implemented when the fragmented files in the cockpit host operating system accumulate to a certain extent, so as to realize the rapid clearing of the fragmented files inside the cockpit host. By quickly clearing the fragmented files inside the cockpit host and then restarting the cockpit host system, it can also effectively solve the problem of cockpit host system abnormality or inability to start the cockpit host due to the accumulation of fragmented files in the cockpit host system.

[0033] Figure 1 A flowchart of a method for clearing fragmented files in a cockpit host in an exemplary embodiment of the present application is shown, including steps S10 to S40. Figure 1 The technical solution of this application will be described in detail.

[0034] First, execute step S10 to obtain a physical key instruction.

[0035] The acquired physical key command is generated by a physical key. Specifically, when it is necessary to clean up the fragmented files of the cockpit host, the physical key command can be obtained by pressing the physical key in the cockpit host. Furthermore, the physical key command is converted into a protocol command to realize the cleaning of the fragmented files according to the protocol command control.

[0036] Before step S10, that is, before obtaining the physical key instruction, the method further includes:

[0037] Step S001: Startup monitoring of the cockpit host;

[0038] Step S002: When the cockpit host cannot be started, select and press the physical key corresponding to the physical key instruction to generate a physical key instruction.

[0039] In this embodiment, the physical key command obtained can be generated according to the startup status of the cockpit host through the corresponding physical key. Specifically, during the startup process of the cockpit host, it can be monitored whether the cockpit host has completed the startup, and when the cockpit host has completed the startup, it means that the accumulation degree of fragmented files has not reached the set threshold, and the fragmented files can be left unprocessed. When the cockpit host cannot be started, it means that the accumulation degree of fragmented files has reached the set threshold, and the physical key command can be generated by selecting and pressing the physical key corresponding to the physical key command, and then the physical key command is obtained and further converted into a protocol command to control the cleaning of fragmented files.

[0040] In step S002, when the cockpit host cannot be started, a physical key corresponding to the physical key instruction is selected and pressed to generate a physical key instruction, including:

[0041] When the cockpit host cannot be started, choose to press two or more preset buttons on the steering wheel to generate physical button commands.

[0042] In this embodiment, during the startup monitoring process of the cockpit host, when it is detected that the cockpit host cannot be started, the selectable physical buttons can be two or more arbitrary buttons pre-set on the steering wheel. By using the two or more arbitrary buttons to press in accordance with the set rule sequence, a physical button instruction is generated after the selection and pressing is completed. The rule sequence can be to press all the preset buttons at the same time, of course, it can also be to press each preset button separately in a set time in a sequence to generate a physical button instruction.

[0043] In step S10, obtaining a physical key instruction includes:

[0044] Get the physical key command generated when pressing the physical key through the Lin bus.

[0045] In this embodiment, a communication connection can be established with a corresponding physical key by utilizing the Lin bus, so that when a pressing signal of a physical key is obtained, a physical key instruction corresponding to the physical key is obtained through the Lin bus.

[0046] Next, step S20 is executed to convert the physical key command into a protocol command.

[0047] After pressing the physical key to obtain the physical key instruction, the physical key instruction needs to be further converted into a protocol instruction, so as to clean up the fragmented files according to the protocol instruction. In this embodiment, when converting the physical key instruction into the protocol instruction, the protocol instruction can be an IPCP protocol instruction.

[0048] Next, step S30 is executed to clean up the fragmented files according to the protocol instructions.

[0049] After obtaining the protocol instructions converted from the physical button instructions, the protocol instructions can be used to further control the cleaning and deletion of the system fragmented files of the cockpit host to solve the problem of cockpit host system abnormalities or even the inability to start the cockpit host due to the accumulation of fragmented files.

[0050] In step S30, the fragmented files are cleaned up according to the protocol instructions, including:

[0051] Step S301: Send the protocol instruction to the driver service;

[0052] Step S302: Sending the protocol instruction to the virtualized operating system through the driver service;

[0053] Step S303: Notify the file service to clean up the fragmented files through the virtualized operating system.

[0054] In this embodiment, after obtaining the protocol instruction according to the physical key instruction, the protocol instruction can be further sent to the driver service, and the protocol instruction can be forwarded to the virtualized operating system (virtualized OS) through the driver service, and the file service is notified through the virtualized operating system, and all fragmented files stored in the operating system of the cockpit host (such as the Android system) are cleaned and deleted through the file service.

[0055] In step S303, the virtualized operating system notifies the file service to clean up the fragmented files, including:

[0056] The virtualized operating system notifies the file service to clean up the storage area where the fragmented files are stored.

[0057] In this embodiment, when fragmented files are cleaned up, the fragmented files are stored separately in a set storage area. Therefore, after the virtualization operating system notifies the file service according to the protocol instructions, the storage area storing the fragmented files can be cleaned up through the file service to achieve rapid cleaning of the fragmented files.

[0058] Next, step S40 is executed, and after the fragmented files are cleaned up, the cockpit host system is restarted.

[0059] After all fragmented files are cleaned and deleted according to the protocol instructions, the cockpit host system is restarted to wake up the cockpit host system.

[0060] In step S40, after the fragmented files are cleaned up, the cockpit host system is restarted, including:

[0061] After the fragmented files are cleaned up through the file service, the cockpit host is notified through the file service to restart the system.

[0062] In this embodiment, after notifying the file service through the virtualized operating system according to the protocol instruction, the file service will clean up the fragmented files, and after the fragmented files are cleaned up, the cockpit host is further notified through the file service to restart the system.

[0063] See also Figure 2 , Figure 2 In the given embodiment, the combination key includes any two or more keys on the steering wheel in the cockpit. When the cockpit host cannot start the system, by pressing the combination key, the physical key instruction generated by the combination key can be passed to the key service through the Lin bus. After the security inspection service receives the physical key instruction corresponding to the combination key, the physical key instruction is converted into an IPCP protocol instruction and passed to the driver service. After the driver service receives the IPCP protocol instruction, the IPCP protocol instruction is passed to the virtualized OS (operating system), and the virtualized OS notifies the file service after receiving the instruction. Then, the file service performs a cleanup action on the fragmented files, and cleans and deletes all fragmented files in the operating system of the cockpit host (such as the Android system). And after the cleanup is completed, the file service notifies the cockpit host to restart the system, thereby realizing the rapid removal of fragmented files inside the cockpit host, and effectively solving the problem of cockpit host system abnormality or inability to start the cockpit host due to the accumulation of fragmented files on the cockpit host system.
