"Connected" or "coupled" or similar terms are not limited to a direct connection, but can include an indirect connection unless otherwise explicitly stated.

[0048] Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art. It will be further understood that terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning that is consistent with their meaning in the context of the relevant art and the present disclosure, and will not be interpreted in an overly literal or overly formal sense unless expressly so defined herein.

[0049] In the technical solutions of the present application, the collection, storage, use, processing, transmission, provision and disclosure of user personal information comply with relevant laws and regulations and do not violate public order and good customs. The use of user data in the technical solutions complies with relevant national laws and regulations (for example, "Information Security Technology Personal Information Security Specification" and the like). For example, appropriate measures are taken for personal information access control; the display of personal information is limited as specified; the use purpose of personal information does not exceed the direct or reasonably related range; the use of personal information eliminates explicit identity pointing and avoids precise positioning to a specific individual.

[0050] With the improvement of the intelligent level of automobiles, the car machine instrument panel, as the core interface for the driver to interact with the vehicle, directly affects the driving experience and safety. The traditional car machine instrument panel generally has the problem of fixed layout, and the user cannot adjust the display position and size of the core content such as vehicle speed, navigation, multimedia information, etc. according to personal use habits and needs, which is difficult to meet the personalized needs. Although some high-end models support limited customization functions, they need to be operated locally through the car machine, which is cumbersome and has specific dependence on hardware, resulting in that the customization functions cannot be adapted across models and devices.

[0051] Meanwhile, the traditional scheme lacks cloud collaboration capability, and the user's personalized configuration can only be stored locally on the vehicle machine and cannot be synchronized to other vehicles or devices, limiting the reusability of the configuration. In addition, the existing custom method does not establish a unified security verification mechanism, which may block key driving information such as vehicle speed and gear due to improper user configuration, posing a driving safety hazard. Moreover, the vehicle machine locally processes layout calculation and rendering tasks, which consumes a large amount of local computing power and shortens the service life of the hardware.

[0052] To solve at least one or more of the above technical problems, the present disclosure provides a mobile terminal and cloud collaborative vehicle machine instrument panel arrangement method and system. Through the collaborative architecture of mobile terminal convenient operation, cloud intelligent adaptation and security verification, and vehicle end precise execution, the personalized customization and cross-device adaptation of the instrument panel are realized, while the driving safety is ensured.

[0053] Figure 1 A structural diagram of a vehicle machine instrument panel arrangement system provided by the present disclosure is shown in Figure 1 The arrangement system includes a mobile terminal, a cloud engine, and a vehicle machine terminal connected to each other.

[0054] The mobile terminal is configured to provide a visual design interface, support the user's drag-and-drop operation of adding, deleting, or modifying the instrument panel controls, generate a layout description file containing control attributes, and have an instrument panel dynamic preview function and a function of calling a cloud service to save the layout description file. The control attributes at least include position, size, and interaction logic.

[0055] The cloud engine is configured to receive the layout description file sent by the mobile terminal, analyze the hardware parameters of the target vehicle machine terminal, process the layout description file in combination with the hardware parameters to generate a configuration file adapted to the target vehicle machine terminal, and perform security compliance verification. The hardware parameters at least include screen size, CPU / GPU performance level, and system version.

[0056] The vehicle machine terminal is configured to receive the configuration file issued by the cloud engine, dynamically load the control resource library and render the instrument panel interface after parsing the configuration file through a configuration parser, and can report the configuration file execution result to the cloud engine in real time, and the execution result is fed back to the mobile terminal synchronously.

[0057] The arrangement system of the vehicle machine instrument panel provided by the present disclosure forms a closed-loop process through the mobile terminal, the cloud engine, and the vehicle machine terminal, ensuring the integrity of the configuration from design to landing, realizing the remote personalized customization and cross-model adaptation of the vehicle machine instrument panel, and laying a foundation for subsequent function expansion.

[0058] The present disclosure also provides a vehicle machine instrument panel arrangement method applied to the above arrangement system. Figure 2A flowchart of a vehicle instrument panel arrangement method provided by an embodiment of the present disclosure is shown in FIG. 1, which comprises steps S1-S3 as follows. Figure 2

[0059] In step S1, the mobile terminal generates a layout description file containing control attributes in response to a user operation of drag-and-drop adjustment of the instrument panel control, and sends the layout description file to the cloud engine.

[0060] In step S2, the cloud engine receives the layout description file, parses the hardware parameters of the target vehicle terminal, processes the layout description file in combination with the hardware parameters to generate a configuration file adapted to the target vehicle terminal, and performs a security compliance check, wherein the hardware parameters at least include screen size, CPU / GPU performance level, and system version.

[0061] In step S3, the vehicle terminal receives the configuration file issued by the cloud engine, dynamically loads the control resource library and renders the instrument panel interface after configuring the configuration file, and uploads the configuration file execution result to the cloud engine, so that the cloud engine feeds back the execution result to the mobile terminal.

[0062] The vehicle instrument panel arrangement method provided by the embodiment of the present disclosure constructs a collaborative architecture of the mobile terminal, the cloud engine, and the vehicle terminal, wherein the mobile terminal serves as an interactive entrance, generates a layout description file containing control attributes in response to a user drag-and-drop operation, and solves the problem of cumbersome local operation of a traditional vehicle; the cloud engine undertakes core processing tasks, adapts the layout by parsing the hardware parameters of the vehicle, and performs a security check to make up for the lack of local computing power and cross-device adaptation defects; and the vehicle terminal is responsible for final configuration parsing and interface rendering, and feeds back the execution result to form a closed loop. In this way, the limitation of the fixed layout of the traditional vehicle instrument panel is broken, the user self-definition threshold is reduced through visual operation of the mobile terminal, cross-device adaptation and unified management of the configuration are realized through cloud collaboration, the vehicle terminal performs light-weight execution to reduce local resource consumption, and the overall architecture realizes the balance between personalization and practicality.

[0063] In some embodiments, the vehicle instrument panel arrangement method can further comprise:

[0064] When the cloud engine processes the layout description file in combination with the hardware parameters, the actual size of the control is calculated by using Formula 1 to adapt the control to the target vehicle terminal, and Formula 1 is: actual width = (user-defined ratio x screen width) - margin compensation value, wherein the margin compensation value is determined by the vehicle screen resolution and the scaling system of the vehicle operating system.

[0065] ​In the control size adaptation method, the size is dynamically adjusted based on the relative proportion defined by the user and the actual hardware parameters of the car machine, so as to avoid layout disorder caused by differences in screens of different car machines. The cross-screen size adaptation problem is solved, and the same user configuration can maintain reasonable display effect on car machines with different resolutions and different scaling ratios, thereby improving the compatibility and consistency of the layout.

[0066] In some embodiments, the arrangement method of the car machine instrument panel can further include:

[0067] The cloud engine stores historical operation data of the mobile terminal user, and recommends a personalized instrument panel template to the mobile terminal based on the historical operation data by using a dynamic push mechanism. The cloud engine also generates a plurality of instrument panel templates according to the user data, for the mobile terminal user to select and save.

[0068] The arrangement method of the car machine instrument panel provided by the embodiments of the present disclosure adds a personalized recommendation mechanism on the basic framework. The cloud engine stores user historical operation data, recommends templates by using a dynamic push mechanism, and generates official templates for selection. This design mines preferences based on user behavior data, reduces repeated manual configuration operations, further optimizes user experience, and reduces the operation cost of personalized configuration. At the same time, the official templates provide professional reference for users, enrich the configuration selection, and improve the practicality and ease of use of the function.

[0069] In some embodiments, the MQTT over TLS protocol with bidirectional authentication is used for data transmission between the mobile terminal and the cloud engine, and between the cloud engine and the car machine terminal, and the data packet transmitted contains a timestamp and a digital signature.

[0070] By using the MQTT over TLS protocol with bidirectional authentication for data transmission, and adding a timestamp and a digital signature in the data packet, the identity of the communication parties is ensured to be trusted, the TLS protocol ensures data transmission encryption, the timestamp and the digital signature prevent replay attacks and data tampering, the data transmission security problem between the cloud and the terminal is solved, identity forgery, data leakage and malicious attacks are prevented, and the security and integrity of user configuration data and car machine operation data are ensured.

[0071] In some embodiments, the step of performing security compliance verification by the cloud engine in step S2 can specifically include:

[0072] The definition at least covers a safety area whitelist of vehicle speed, gear position, and corresponding mandatory display area of alarm information; during the process of designing the dashboard layout by the mobile terminal user, the cloud engine detects the overlap conflict between the control and the area in the safety area whitelist in real time, and sends an adjustment prompt to the mobile terminal; the dashboard layout that has been issued to the vehicle terminal and deployed is periodically inspected, and if an abnormal configuration is found, a rollback mechanism is triggered to restore the dashboard layout to the default configuration.

[0073] The above-mentioned safety compliance verification method can detect layout conflicts in real time and prompt adjustments, and periodically inspect deployed layouts and trigger abnormal rollback, thereby eliminating the risk of users blocking critical driving information due to improper configuration. Through automatic verification and abnormal processing mechanisms, the safety bottom line of driving is maintained while meeting individual needs, achieving the unity of individualization and compliance, and further ensuring driving safety.

[0074] In some embodiments, the hardware parameters of the target vehicle terminal are parsed in step S2, and the layout description file is processed in combination with the hardware parameters, which can specifically include:

[0075] An automatic rasterization algorithm based on the screen aspect ratio and pixel density of the vehicle terminal is used to convert the relative coordinates of the controls designed by the mobile terminal user into absolute pixel values; if the target vehicle terminal is a low-performance vehicle terminal, a resource degradation strategy of replacing vector graphics with bitmap and reducing the number of transparent layers is used.

[0076] That is, the processing method of the layout description file proposes specific algorithms and strategies for hardware adaptation. The automatic rasterization algorithm is used to convert relative coordinates into absolute pixel values, and resource degradation strategies such as replacing vector graphics with bitmap and reducing the number of transparent layers are used for low-performance vehicles, thereby taking into account screen adaptation accuracy and hardware performance differences, improving the accuracy of layout adaptation, and ensuring that control positions and sizes are accurately displayed on screens with different pixel densities; at the same time, a lightweight solution is provided for low-performance vehicles to avoid interface lag caused by excessive resource consumption, ensuring smooth operation experience for vehicles with different performance levels.

[0077] In some embodiments, the vehicle terminal dashboard arrangement method can further include:

[0078] When the vehicle is in a driving state, the vehicle terminal automatically hides unnecessary interactive controls; when the vehicle is in a parked state, the vehicle terminal opens complete dashboard customization functions.

[0079] In combination with the above method, it can be concluded that the vehicle machine terminal can optimize the interface display in combination with the vehicle running state, automatically hide unnecessary interaction controls in the driving state, and open complete custom functions in the parking state, thereby dynamically adjusting the interface based on the driving scene, prioritizing driving concentration, realizing the adaptation of the interface display to the driving scene, reducing visual interference during driving, and reducing driving risk. At the same time, complete customization freedom is provided when parking, taking into account safety and personalized needs, and improving the scene adaptability of the function.

[0080] The arrangement method of the vehicle machine instrument panel provided by the embodiments of the present disclosure can realize free design of the instrument panel interface by the visual drag operation and dynamic preview function of the mobile terminal, reduce operation cost in combination with personalized template recommendation, and fully meet personalized needs. At the same time, the interface is dynamically adjusted in the driving and parking states, taking into account the convenience of use and driving concentration.

[0081] The cloud engine undertakes core tasks such as layout calculation and adaptation processing, greatly reduces the computing power pressure of the vehicle machine terminal, reduces hardware loss, and prolongs the service life of the device; the resource degradation strategy for low-performance vehicle machines further ensures smooth operation of vehicle machines with different hardware levels.

[0082] Through the safety area white list, real-time conflict detection, periodic inspection, and abnormal rollback mechanism, it is ensured that key driving information such as vehicle speed and gear position is not blocked; the two-way authentication encryption transmission protocol prevents data security risks, and realizes the unity of personalization and security.

[0083] The arrangement method of the vehicle machine instrument panel provided by the embodiments of the present disclosure will be described in detail below with specific examples in combination with the accompanying drawings. Figure 3 As shown in FIG. 1, another flowchart of the arrangement method of the vehicle machine instrument panel provided by the embodiments of the present disclosure is shown, which comprises steps S01-S10, and the details are as follows: Figure 3

[0084] Step S01, the mobile terminal provides a drag-type visual interface, and generates an instrument panel template containing control attributes in response to user operation. The above control attributes at least include position, size, interaction logic, etc.

[0085] Step S02, after the user completes the template design, the user performs dynamic preview on the instrument panel effect arranged by himself through the preview function of the mobile terminal, and confirms whether it meets the expectation.

[0086] Step S03, after the user confirms the preview effect, the user triggers an upload operation through the mobile terminal, and sends the designed instrument panel template to the cloud engine.

[0087] ​Step S04, the cloud engine receives the template uploaded by the mobile terminal, parses the parameters contained in the template, and synchronously parses the hardware parameters of the target vehicle terminal, such as screen size, CPU / GPU performance, system version, etc.

[0088] Step S05, the cloud engine generates a configuration file adapted to the vehicle terminal according to the parsed template parameters and the vehicle hardware parameters, and stores the configuration file and related data.

[0089] Step S06, the cloud engine issues the adapted template configuration file to the corresponding vehicle terminal.

[0090] Step S07, the vehicle terminal receives the template configuration file issued by the cloud engine, parses the file through a configuration parser, and completes the related configuration of the instrument panel according to the parsing result.

[0091] Step S08, the vehicle terminal dynamically loads the control resource library according to the result after parsing the configuration, and renders to generate an instrument panel interface that meets the user's design.

[0092] Step S09, the vehicle terminal reports the execution result of the instrument panel configuration and rendering to the cloud engine in real time.

[0093] Step S10, the cloud engine synchronously feeds back the above execution result to the mobile terminal to prompt the user that the instrument panel configuration is successful.

[0094] Based on the same inventive concept, the disclosure embodiment also provides a vehicle instrument panel arrangement method applied to a cloud engine. Figure 4 As shown in FIG. 1, the method comprises steps S1'-S4', which are as follows: Figure 4

[0095] Step S1', receive the layout description file sent by the mobile terminal, the layout description file is generated by the mobile terminal through the visual design interface to support the user to add, delete or modify the instrument panel control through the drag-and-drop operation, and contains at least the control attributes covering position, size, and interaction logic.

[0096] Step S2', parse the hardware parameters of the target vehicle terminal, the hardware parameters at least include screen size, CPU / GPU performance level, system version, and the layout description file is processed to generate a configuration file adapted to the target vehicle terminal in combination with the hardware parameters.

[0097] Step S3', perform a security compliance check, and issue the configuration file passing the check to the target vehicle terminal.

[0098] ​Step S4': Receive the configuration file execution result reported by the target vehicle terminal and send the execution result back to the mobile terminal.

[0099] The above-mentioned arrangement method for vehicle dashboards applied to cloud engines clarifies the core process of cloud engines receiving layout description files, parsing hardware parameters, generating adaptive configurations, performing verification, distributing configurations, and providing feedback results. Through centralized processing, cloud engines achieve standardized adaptation and security control of configurations, significantly reducing the computing power pressure on vehicle terminals, reducing hardware wear and tear, and extending equipment lifespan. The resource degradation strategy for low-performance vehicle systems further ensures the smooth operation of vehicle systems with different hardware levels.

[0100] In some embodiments, step S02 may specifically include: using an automatic rasterization algorithm based on the aspect ratio and pixel density of the vehicle screen to convert the relative coordinates of the controls in the layout description file into absolute pixel values; if the target vehicle terminal is a low-performance vehicle terminal, a resource degradation strategy of replacing vector graphics with bitmaps and reducing the number of transparent layers is adopted.

[0101] In some embodiments, step S03 may specifically include: defining a whitelist of safe areas that at least covers the mandatory display areas corresponding to vehicle speed, gear position, and alarm information; detecting overlap and conflict between controls in the layout description file and areas in the whitelist of safe areas in real time, and sending adjustment prompts to the mobile terminal; periodically inspecting the dashboard layout corresponding to the configuration file that has been distributed to the vehicle terminal, and triggering a mechanism to roll back to the default configuration when abnormal configuration is found.

[0102] In some embodiments, the method further includes the step of pushing templates via a cloud engine: storing historical operation data of mobile terminal users, generating personalized dashboard templates based on the historical operation data and dynamically pushing them to the mobile terminal, and generating official dashboard templates based on a large amount of user data for mobile terminal users to choose and save.
