Detailed Implementation

[0020] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0021] This application provides a device control method, apparatus, computer device, and storage medium. The case comparison query device can be integrated into the computer device, which can be a server. The server can be a standalone physical server, a server cluster or distributed system composed of multiple physical servers, or a cloud server providing basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communication, middleware services, domain name services, security services, content delivery networks (CDNs), and big data and artificial intelligence platforms.

[0022] The following sections provide detailed descriptions of each example. It should be noted that the order in which the embodiments are described is not intended to limit the preferred order of the embodiments.

[0023] Please continue reading. Figure 1 , Figure 1 This is a flowchart illustrating a control method applied to an in-vehicle electronic control unit 100 according to an embodiment of this application. The in-vehicle electronic control unit 100 includes multiple hardware security modules, and the control method specifically includes the following steps: 110. In response to the startup of the vehicle infotainment system, obtain screen information of multiple vehicle infotainment screens associated with the vehicle infotainment system.

[0024] The in-vehicle infotainment system described herein is applied to vehicles for controlling vehicle driving, braking, and smart applications. In some embodiments of this application, the in-vehicle infotainment system may include a host module, a screen status judgment module, a handwriting keyboard module, a handwriting trajectory recognition module, and a screen interface module. The functions of each module are described below: Host module: As the core control unit of the entire vehicle infotainment system, it is responsible for coordinating the work between various modules, receiving user input commands, and scheduling the corresponding modules for processing. It should be noted that in some embodiments of this application, each screen has a corresponding host module.

[0025] Screen Status Determination Module: When the vehicle infotainment system starts up, this module determines whether each vehicle screen supports handwriting functionality and sends the result to the host module. This module communicates with the vehicle screen's hardware interface to obtain screen information and determines whether the screen supports handwriting based on preset rules.

[0026] Handwriting keyboard module: Provides a handwriting input interface. When the user triggers a handwriting input operation, the handwriting keyboard module is displayed on the corresponding vehicle screen and receives the user's handwriting trajectory input.

[0027] Handwriting trajectory recognition module: For in-vehicle infotainment screens that do not support handwriting recognition, the host module initializes the handwriting trajectory recognition module when the in-vehicle system starts up. This module has handwriting trajectory recognition capabilities and can convert received handwriting trajectories into candidate text.

[0028] Screen interface module: Includes a handwriting-enabled screen interface and a general screen interface. The handwriting-enabled screen interface is used to communicate with vehicle infotainment screens that support handwriting, directly calling the handwriting interface exposed by the vehicle infotainment screen to implement handwriting functionality; the general screen interface is used to transmit data with vehicle infotainment screens that do not support handwriting, transmitting the handwriting trajectory to the handwriting trajectory recognition module and receiving the candidate text returned by the handwriting trajectory recognition module.

[0029] A vehicle infotainment screen refers to a screen installed in a vehicle and controlled by a vehicle infotainment system. For example, a vehicle infotainment screen can refer to the vehicle's central control screen, or it can refer to a large screen providing entertainment services to passengers in addition to the central control screen. In some embodiments of this application, the vehicle infotainment system is associated with multiple vehicle infotainment screens. For example, a vehicle controlled by the vehicle infotainment system can simultaneously have a central control screen, multiple entertainment sub-screens, etc., to provide a better riding and driving experience for passengers and the driver.

[0030] Screen information refers to the information on the vehicle's infotainment screen. In some embodiments of this application, screen information may refer to the screen's hardware information, such as the screen's resolution and supported handwriting parameters.

[0031] refer to Figure 2 In some embodiments of this application, when the vehicle infotainment system is started, for example when the driver starts the vehicle, screen information of multiple vehicle infotainment screens associated with the vehicle infotainment system is obtained, including: 1101. Obtain the hardware interface of each of the multiple vehicle infotainment screens.

[0032] 1102. Communicate with the hardware interface of each vehicle infotainment screen to obtain the hardware information of each screen.

[0033] When the vehicle infotainment system starts up, the screen status judgment module scans each vehicle infotainment screen and obtains screen information by communicating with the hardware interface of the vehicle infotainment screen.

[0034] 120. Determine the first vehicle infotainment screen and the second vehicle infotainment screen from multiple vehicle infotainment screens based on the screen information.

[0035] The first in-vehicle infotainment screen can convert handwritten traces into displayed content, meaning it supports handwriting recognition. The second in-vehicle infotainment screen cannot convert handwritten traces into displayed content, meaning it does not support handwriting recognition. This is understandable, as not every in-vehicle infotainment screen has a high handwriting recognition usage rate. To reduce costs, during vehicle manufacturing, screens supporting handwriting recognition can be used for frequently used screens such as the central control screen, while screens without handwriting recognition can be used for less frequently used screens such as entertainment auxiliary screens. Therefore, identifying the first and second in-vehicle infotainment screens is essentially determining whether each screen supports handwriting recognition, allowing the determination result to be sent to the host module.

[0036] After obtaining the screen information, the screen status judgment module determines whether each vehicle screen supports handwriting function based on the screen information, and sends the judgment result to the corresponding host module.

[0037] 130. Record the interface information of the first vehicle infotainment screen.

[0038] After the host module obtains the judgment result, for the vehicle infotainment screen that supports handwriting, namely the first vehicle infotainment screen, the host module records its handwriting interface information.

[0039] 140. If the vehicle screen is a second vehicle screen, then initialize the handwriting trajectory recognition module for the vehicle screen.

[0040] For screens that do not support handwriting, i.e., the second vehicle infotainment screen, the host module initializes the handwriting trajectory recognition module. Initialization operations include setting the maximum number of feedback characters and the stroke interval time, among other initialization parameters, and then sending these parameters to the handwriting trajectory recognition module. For example, the host module can send these initialization parameters to the handwriting trajectory recognition module after setting them to enable handwriting feedback. For different second vehicle infotainment screens, the handwriting trajectory recognition module can initialize according to different initialization parameters and return an initialization handle; different vehicle infotainment screens can obtain different handles.

[0041] 150. Receive the target's handwritten trajectory on the target vehicle's infotainment screen; When a user (driver or passenger) triggers a handwriting keyboard operation on any in-vehicle infotainment screen, the handwriting keyboard module displays a handwriting input interface on the target in-vehicle infotainment screen, and the in-vehicle system receives the target handwriting trajectory on the target in-vehicle infotainment screen.

[0042] 150A. If the target vehicle screen is the first vehicle screen, then the display content is generated based on the target handwriting trajectory through the target vehicle screen; If the target vehicle screen supports handwriting, the handwriting keyboard module directly calls the handwriting interface exposed by the target vehicle screen through the handwriting support screen interface, transmits the user's target handwriting trajectory to the target vehicle screen for processing, and the screen returns the displayed content (candidate text).

[0043] 150B. If the target vehicle screen is a second vehicle screen, the handwriting trajectory recognition module associated with the second vehicle screen generates the display content based on the target handwriting trajectory.

[0044] In the existing multi-screen environment of in-vehicle infotainment systems, the implementation of handwriting functionality mainly takes the following forms: 1. Unified Hardware Solution: Some in-vehicle infotainment systems require all screens to be equipped with a handwriting hardware module to ensure that handwriting functionality can be directly implemented on each screen. With this solution, the system does not need complex adaptations for different screens; it can directly call the screen's own handwriting interface to complete handwriting operations.

[0045] 2. Single Software Adaptation Solution: For some in-vehicle infotainment systems that only support handwriting on specific screens, the software is only developed and adapted for the screens that support handwriting. When a user attempts to handwrite on a screen that does not support handwriting, the system cannot provide the corresponding function or will display an unsupported message.

[0046] After obtaining the content, you can display it through the handwriting keyboard module, such as displaying candidate text.

[0047] The existing solution has the following problems: For a unified hardware solution: 1. High cost: Requiring all screens to be equipped with handwriting hardware modules significantly increases the hardware cost of the vehicle infotainment system. This is especially true for large vehicle infotainment systems, where hardware upgrades for multiple screens can lead to a significant increase in overall cost.

[0048] 2. Waste of resources: In some practical application scenarios, not all screens need to use the handwriting function frequently, and uniformly equipping handwriting hardware leads to idle and wasted resources.

[0049] For a single software adaptation solution 1. Significant functional limitations: It cannot meet the diverse needs of users for handwriting input on different screens, thus reducing the user experience. Especially in in-vehicle infotainment systems that work with multiple screens, users may want to be able to easily perform handwriting input on any screen.

[0050] 2. Lack of flexibility: Software adaptation is only for specific screens. When the screen configuration of the vehicle system changes (such as replacing the screen, adding or reducing the number of screens), a lot of software development and adaptation work needs to be carried out again, which increases the system maintenance cost and development cycle.

[0051] Therefore, the display content generation method provided in this application embodiment, in response to the startup of the vehicle system, obtains screen information of multiple vehicle screens associated with the vehicle system; determines a first vehicle screen and a second vehicle screen from the multiple vehicle screens based on the screen information, to determine whether the multiple vehicle screens support handwriting function, and sends the determination result to the host module, wherein the first vehicle screen can convert handwriting trajectory into display content, and the second vehicle screen cannot convert handwriting trajectory into display content; records the interface information of the first vehicle screen; if the vehicle screen is the second vehicle screen, initializes the handwriting trajectory recognition module for the vehicle screen; receives the target handwriting trajectory on the target vehicle screen; if the target vehicle screen is the first vehicle screen, generates display content based on the target handwriting trajectory through the target vehicle screen; if the target vehicle screen is the second vehicle screen, generates display content based on the target handwriting trajectory through the handwriting trajectory recognition module associated with the second vehicle screen. Therefore, in a multi-screen environment of the vehicle infotainment system, it is not necessary for all screens to directly implement handwriting functionality. By using an additional handwriting trajectory recognition module, handwriting trajectory recognition services can be provided for the second vehicle infotainment screen that does not support handwriting functionality, so as to generate display content from the target handwriting trajectory, thereby reducing hardware costs and saving resources.

[0052] For ease of understanding, the following provides an execution flow of a display content generation method. In this embodiment, the vehicle system includes a host module, a screen state judgment module, a handwriting keyboard module, a handwriting trajectory recognition module, and a screen interface module. The functions of each module are as described above and will not be elaborated further. (Reference) Figure 3 During the vehicle infotainment system startup phase, after the system boots up, the screen status judgment module scans each screen, obtains screen information through hardware interfaces, and then determines whether the screen supports handwriting functionality, sending the result to the host module. If the screen supports handwriting, the corresponding host module records the handwriting screen's interface information. If the screen does not support handwriting, the host module initializes the handwriting trajectory recognition module. Subsequently, the handwriting input phase begins. First, when the user initiates a handwriting keyboard operation on any screen, the handwriting keyboard module displays the handwriting input interface. If the current screen supports handwriting, the handwriting keyboard module calls the screen's handwriting interface through the supported handwriting screen interface. The screen processes the handwriting trajectory and returns the display result (e.g., candidate text). If the current screen does not support handwriting, the handwriting keyboard module transmits the handwriting trajectory to the handwriting trajectory recognition module through the general screen interface. The handwriting trajectory recognition module recognizes the handwriting trajectory and generates the display result (e.g., candidate text). The handwriting trajectory recognition module returns the display result to the handwriting keyboard module through the general screen interface, and the handwriting keyboard module displays the content.

[0053] To facilitate better implementation of the display content generation method provided in this application embodiment, a display content generation apparatus is also provided in one embodiment. The meanings of the terms used are the same as in the above-described display content generation method, and specific implementation details can be found in the description of the method embodiment.

The determining unit 202 is used to determine the first vehicle screen and the second vehicle screen from multiple vehicle screens based on screen information, so as to determine whether the multiple vehicle screens support handwriting function, and then send the determination result to the host module. The first vehicle screen can convert handwriting traces into display content, while the second vehicle screen cannot convert handwriting traces into display content. Recording unit 203 is used to record the interface information of the first vehicle screen; Initialization module 204 is used to initialize the handwriting trajectory recognition module for the vehicle screen if the vehicle screen is the second vehicle screen; The receiving unit 205 is used to receive the target handwritten trajectory on the target vehicle screen; The generation unit 206 is used to generate display content based on the target handwriting trajectory through the target vehicle screen if the target vehicle screen is a first vehicle screen; and to generate display content based on the target handwriting trajectory through the handwriting trajectory recognition module associated with the second vehicle screen if the target vehicle screen is a second vehicle screen.

[0059] Although not shown, the server may also include a display unit, etc., which will not be described in detail here. Specifically, in this embodiment, the processor 1001 in the server loads the executable files corresponding to the processes of one or more computer programs into the memory 1002 according to the following instructions, and the processor 1001 runs the computer programs stored in the memory 1002 to realize various functions, as follows: In response to the startup of the vehicle infotainment system, obtain screen information from multiple vehicle infotainment screens associated with the vehicle infotainment system; Based on screen information, a first vehicle screen and a second vehicle screen are determined from multiple vehicle screens. The first vehicle screen can convert handwritten traces into display content, while the second vehicle screen cannot.
