The IP address or the MAC address of the vehicle-mounted slave control device is only an exemplary scheme, and is not limited to the IP address or the MAC address, and all the identifiers capable of uniquely identifying the vehicle-mounted slave control device are within the protection scope of the technical scheme.

After the connection of the wireless local area network is established, the vehicle-mounted master control device needs to transmit personalized interfaces corresponding to at least one vehicle-mounted slave control device to the slave control devices respectively.

Further, before the step S11, a personalized interface corresponding to at least one vehicle-mounted slave control device is generated by:

Firstly, the vehicle-mounted master control device configures corresponding user permissions for users logged in on at least one vehicle-mounted slave control device in advance, for example: user permissions are divided into three levels: senior users, ordinary users, and guest users; the advanced users have the authority of modifying configuration and the like, and the application of the advanced users can preempt and interrupt the application resources of other users; the common user can not seize the application resource which is being used by the advanced user, and the visitor user uses the application resource according to the time sequence, so that the user data of the common user can be reserved; the visitor user and the ordinary user use the application resources in chronological order, but after the visitor user exits, the user data of the visitor user is erased. Different application options can be used under different user rights, and for example, advanced users can use phone-related applications and office-related applications; common users can use office related applications and entertainment related applications; the guest user can only use entertainment-related applications. The phone-related application, the office-related application and the entertainment-related application correspond to at least one application in three categories, and exemplarily, the phone-related application comprises a phone a and a phone B, the office-related application comprises an office a and an office B, and the entertainment-related application comprises an entertainment a and an entertainment B. The vehicle-mounted main control equipment sets different user permissions according to the login position of a user in the vehicle for the first time, for example: if a user logs in the auxiliary driving vehicle-mounted slave control equipment for the first time, the vehicle-mounted master control equipment configures the user into a high-level user authority; if a user logs in the left rear row vehicle-mounted slave control device for the first time, the vehicle-mounted master control device configures the user as a common user permission; if the user logs in from the right rear row of vehicle-mounted slave control equipment for the first time, the vehicle-mounted master control equipment configures the user as the visitor user permission.

The vehicle-mounted master control equipment determines application options corresponding to user permissions according to the user permissions corresponding to the users logged in the at least one vehicle-mounted slave control equipment, and all applications contained in the application options are issued to the vehicle-mounted slave control equipment logged in by the users through the wireless local area network; the user carries out personalized selection on all applications contained in the application options through a touch screen of the vehicle-mounted slave control equipment, a corresponding touch instruction is generated in the selection process, and after the selection is finished, the touch instruction is forwarded to the vehicle-mounted master control equipment through the wireless local area network; the vehicle-mounted master control equipment receives a touch instruction of the vehicle-mounted slave control equipment, which is forwarded by the vehicle-mounted slave control equipment through the wireless local area network; the vehicle-mounted main control equipment analyzes the touch instruction so as to determine information of at least one application selected from the application options by the user; the vehicle-mounted master control equipment stores the analyzed information of the at least one application selected by the user and the user association into a configuration file, and generates a personalized interface corresponding to the user on the vehicle-mounted slave control equipment according to the information of the at least one application. And when the user logs in again, the configuration file is directly loaded, and the personalized interface corresponding to the application information selected by the user before is transmitted to the vehicle-mounted slave control equipment logged in by the user.

The vehicle-mounted master control equipment generates a personalized interface corresponding to a user on the vehicle-mounted slave control equipment, and after transmission of the personalized interface is completed, the user can use an application in the personalized interface through a touch screen of the vehicle-mounted slave control equipment and forwards request information to the vehicle-mounted master control equipment, the vehicle-mounted slave control equipment can only recognize and receive touch instruction information of the user on the touch screen and forwards the touch instruction information, the vehicle-mounted slave control equipment does not have more information processing capacity, the processing of the touch instruction information and the request information depends on the processing capacity of the vehicle-mounted master control equipment, and the vehicle-mounted master control equipment processes the request information through the following scheme.

Further, the step S12 can be specifically realized by the following process:

the vehicle-mounted main control equipment analyzes the touch coordinate and determines an operation instruction of the user on the personalized interface;

The user carries out touch clicking on the application in the personalized interface through a touch screen of the vehicle-mounted slave control equipment, a corresponding touch instruction is generated by the action of the touch clicking, the touch instruction comprises touch coordinates, and after the action of the touch clicking is finished, the vehicle-mounted slave control equipment forwards the generated touch instruction to the vehicle-mounted master control equipment; after the on-board master control device receives a touch instruction of the on-board slave control device to the personalized interface forwarded by the wireless local area network, the on-board master control device analyzes touch coordinates in the touch instruction, and in the analyzing process, the on-board master control device reads a corresponding personalized interface stored in the on-board master control device and corresponds to the personalized interface through the touch coordinates, so that an operation instruction of the user to the personalized interface can be determined, wherein the operation instruction comprises an application operated by the user and an action operated by the user, such as an operation of starting the application to an entertainment A application; the vehicle-mounted master control equipment processes the application operated by the user and the action of the operation, generates a processing result interface, such as a main page or an application login page after the entertainment A application is started, and returns the processing result interface to the corresponding vehicle-mounted slave control equipment through the wireless local area network; after the vehicle-mounted slave control device receives the processing result page, the next touch instruction to the personalized interface can be performed through the touch screen again, for example, after login information is input into the login page, a login button is clicked through touch, the touch instruction is forwarded to the vehicle-mounted master control device again, and the processing result page with login success or login failure is received; and carrying out multiple requests as described above, thereby realizing interaction between the vehicle-mounted master control equipment and the vehicle-mounted slave control equipment.

Under the condition that at least two vehicle-mounted slave control devices request applications in the vehicle-mounted master control device, if the at least two vehicle-mounted slave control devices respectively request different applications on the vehicle-mounted master control device, the vehicle-mounted master control device respectively processes corresponding requests and returns a processing result page to the corresponding vehicle-mounted slave control device; if at least two vehicle-mounted slave control devices request the same application on the vehicle-mounted master control device, a competition request situation occurs, and aiming at the competition request situation, the invention processes through the following scheme.

Further, the step S12 can be specifically realized by the following scheme:

when at least two vehicle-mounted slave control devices request the application non-simultaneously and have the same priority, the application is allocated to the vehicle-mounted slave control device with the front request time sequence for use;

After the user logs in the vehicle-mounted slave control device, the user authority is configured by the vehicle-mounted master control device, and as described above, the user authority is exemplarily divided into three levels: senior users, ordinary users, and guest users; the at least one vehicle-mounted slave control device correspondingly has different priorities according to the users with different user permissions logged in the vehicle-mounted slave control device; if the user authority is a high-level user, the priority of the vehicle-mounted slave control equipment logged in by the user is a first priority; if the user authority is a common user, the priority of the vehicle-mounted slave control equipment logged in by the user is a second priority; and if the user authority is the visitor user, the priority of the vehicle-mounted slave control equipment logged in by the user is a third priority. The priority is a first priority, a second priority and a third priority from high to low in sequence.

When at least two vehicle-mounted slave control devices request the same application at the same time, the application is allocated to the vehicle-mounted slave control device with higher priority for use, and prompt information is returned to the vehicle-mounted slave control device with lower priority, for example: the application is being used, please try again later; and after the application is used by the vehicle-mounted slave control equipment with higher priority, distributing the application to the vehicle-mounted slave control equipment with lower priority for use.

When at least two vehicle-mounted slave control devices request the same application non-simultaneously and have the same priority, the application is allocated to the vehicle-mounted slave control device with the front request time sequence for use, and prompt information is returned to the vehicle-mounted slave control device with the back request time sequence, for example: the application is being used, please try again later; and after the application is used by the vehicle-mounted slave control equipment with the front request time sequence, distributing the application to the vehicle-mounted slave control equipment with the back request time sequence for use.

Under the condition that at least two vehicle-mounted slave control devices request the same application non-simultaneously and have different priorities, the application is firstly allocated to the vehicle-mounted slave control device with the front request time sequence for use, when the vehicle-mounted slave control device with the rear request time sequence has higher priority, the application is interrupted from being used, application resources are released, and then the application is allocated to the vehicle-mounted slave control device with the higher priority for use; when the priority of the vehicle-mounted slave control device with the later request time sequence is lower than or equal to the priority of the vehicle-mounted slave control device with the earlier request time sequence, the vehicle-mounted slave control device with the earlier request time sequence is waited to use the application, and then the application is allocated to the vehicle-mounted slave control device with the later request time sequence for use.

When the at least two vehicle-mounted slave control devices request the same application at the same time and have the same priority, returning prompt information to the at least two vehicle-mounted slave control devices, for example: the application is being used, please try again later.

In order to ensure driving safety, some request information is set as vehicle safety related requests in advance, and in the driving process of a vehicle, when the vehicle has related safety problems, the vehicle safety related requests are sent to vehicle-mounted main control equipment to remind drivers and passengers of carrying out corresponding processing, so that the driving safety of the vehicle is ensured, and aiming at the situation, the method can be processed by the following scheme:

Through the mode, the user carries out personalized configuration on favorite applications through the vehicle-mounted slave control equipment and generates a personalized interface corresponding to the user through the vehicle-mounted master control equipment, so that better use experience is provided for drivers and passengers.

The following describes the method for interaction between the vehicle-mounted driver and passenger auxiliary devices in detail by taking a vehicle-mounted video and audio entertainment system as an example:

in this embodiment, the vehicle-mounted driver and passenger auxiliary device comprises a vehicle-mounted main control device and three vehicle-mounted slave control devices, the vehicle-mounted main control device is an intermediate control screen (IVI), the vehicle-mounted slave control devices comprise a secondary driving screen (CDI) and a rear Row Screen (RSE), and the rear row screen comprises a left rear row screen and a right rear row screen. In the present embodiment, the system devices of the center control screen, the front passenger screen, and the rear row screen establish a wireless local area network through the WLAN as a transmission medium. In the wireless local area network, the central control screen is configured to be softAP, the copilot screen and the rear row screen are configured to be STA (Station), and through the configuration, the copilot screen and the rear row screen can be connected to the central control screen serving as the softAP through Wi-Fi as the STA. The network connection mode has the following beneficial effects: the first and the rear row screens do not need to have independent internet access modules, and network access can be completed through the internet access module of the central control screen; usually, the central control screen is externally connected with an internet module, in this embodiment, the central control screen is used as a SoftAP, and IPTables (routing tables) can be configured and NAT (network address translation) can be set, so that a network data link is smooth, and an internet access between the copilot screen and the rear row screen is realized; secondly, access security management can be carried out on the accessed system equipment at the central control screen side, so that security control is realized; for example, white list management: and setting the MAC addresses of the copilot screen and the rear row screen into a white list configuration file in a central control screen, and starting a white list function to prevent unauthorized equipment from being added into the wireless local area network, so that the risk of network interference and intrusion is reduced.

By the mode, after the network connection among the rear row screen, the assistant driving screen and the central control screen is completed, a data transmission channel of a physical link is provided for each vehicle-mounted audio-video entertainment device. After the network connection is established, the central control screen monitors the online state of the rear row screen or the assistant driving screen connected in the network, and when the rear row screen or the assistant driving screen is monitored to be in an offline state, the central control screen can establish wireless local area network connection with the rear row screen or the assistant driving screen again.

After physical connections are established among a plurality of audio-visual entertainment devices, corresponding upper protocol stacks are required to be deployed to support service logic. The most important technical points of the embodiment are three: the first screen, the copilot screen and the rear row screen equipment are identified after being accessed to a wireless local area network where a central control screen is located; secondly, the main central control screen system can transmit the customized individual desktop for the secondary driving screen and the rear row screen and other application running interfaces to the corresponding secondary driving screen or the rear row screen in real time; and thirdly, the application or service provided by the main central control screen system can be operated through the touch screen of the auxiliary driving screen or the rear row screen. In order to implement the above technical points, the present embodiment uses a UPnP protocol as a basis for completing basic work such as discovery, description, and control, and uses a VNC (Virtual Network Computing) as a display and input protocol for completing display of a desktop and control of a touch event; the UPnP relies on application layer protocols such as HTTP, SOAP, SSDP and the like to provide support for the UPnP, the VNC relies on RFB (Remote Frame Buffer) to provide support for the VNC, and meanwhile, the UPnP and the VNC are built on a TCP/IP protocol cluster; the design and the deployment of the corresponding protocol stack are completed through the method.

In this embodiment, corresponding control software components and business software components need to be respectively deployed in the server (central control screen) and the client (copilot screen and back row screen) to complete the implementation of the functions and the deployment of the software. Taking the Android operating system as an example, the software module architecture of the server includes: application option resources, a configuration management module, a device management module, a task management module, a desktop generator, a service provider, a picture synthesizer, etc.

The application option resources of the central control screen comprise a plurality of audio-visual entertainment applications, such as a video player and a music player, different applications can be configured for desktops of the secondary driving screen and the rear row screen through a configuration management module in the basic component, then a corresponding personalized desktop layout is generated through a desktop generator, pictures of the desktop are coded through a picture synthesizer, and then the pictures are sent to the secondary driving screen and the rear row screen through a network according to a coding format (determined by a hardware system) supported by the system. The equipment management is mainly used for managing the connected rear row screen and the auxiliary driving screen. The task manager is used for processing task requests sent by the front-driving screen or the rear-row screen, and processing possible competition requests according to the priority strategy. The service provider is used for providing service interface mapping provided on the central control screen for the auxiliary driving screen or the rear row screen to be called, the service interfaces are integrated into the auxiliary driving screen and the rear row screen in an IPC Client library mode, and a corresponding mapping relation is formed between the service interfaces and the IPCServer in the central control screen. Taking the screen resolution setting interface setscreen resolution () as an example, referring to fig. 3, the process of implementing the screen resolution setting function is specifically described below:

s31, a user clicks a resolution setting function icon through a touch screen;

s32, reading current screen resolution configuration from a configuration file of the copilot screen and displaying the screen resolution configuration;

s33, modifying the configuration field and requesting the change of the control screen side by calling a setDsiplayresolution interface;

s34, reading the screen resolution ratio set before the copilot screen from the stored configuration by the central control screen side;

s35, comparing the read configuration with the written configuration;

s36, if the two values are the same, refusing the writing request and informing the result to the assistant driving screen;

s37, if the two values are different, writing new configuration for reading when generating the picture;

and S38, returning a successful result to the assistant driving screen.

Through the steps, the function of setting the screen resolution is realized.

In order to ensure high real-time performance of an interaction process between the vehicle-mounted master control device and the slave control device, on the vehicle-mounted slave control device, such as a secondary driving screen, each touch click of a user generates a corresponding touch instruction, the touch instruction of each user is processed by a channel on the side of the central control screen, and a port is independently allocated for processing the touch instruction, so that the high real-time performance is ensured, and the fluency of user experience is improved.

In order to ensure that in the interaction process, the vehicle-mounted master control equipment can correctly return the corresponding processing result to the corresponding vehicle-mounted slave control equipment, each vehicle-mounted slave control equipment such as a secondary driving screen or a rear row screen has a UUID (universal unique identification code), when a request is sent to the central control screen, the central control screen can create an independent service for the independent secondary driving screen or the rear row screen, the service can carry the UUID and send the request together, then the central control screen can judge which equipment requests according to a UUID field, and when the processing result is returned, the IP address of the equipment can be increased, the service corresponding to each secondary driving screen or the rear row screen is communicated with the corresponding equipment, and the processing result is transmitted to the secondary driving screen or the rear row screen sending the request so as to ensure that the corresponding processing result is correctly returned to the corresponding equipment.

The client is arranged in the front row screen and the rear row screen, and has the main tasks of receiving and displaying real-time personalized interface pictures transmitted by the server, transmitting touch key events operated by users on the rear row screen and the front row screen to the server and processing the touch key events by the central control screen. The secondary driving screen and the rear row screen serving as the client allow a plurality of users to log in alternately, namely, only one user can be in a login state in one time period in one secondary driving screen or rear row screen, and the next user can log in after the user logs out. Compared with a server, a client software deployment architecture is relatively simple, and mainly comprises: a connection management module, a desktop display, a client manager, and other modules.

The connection management module is mainly responsible for the work of connection logic, connection state and the like with the server; the desktop display decodes the received desktop graphic video coding by using a video decoder of the system; the client manager implements comparison-based capability support, such as configuration of network parameters, return of touch events, and the like.
