Description

Technical Field

[0001] This application relates to the field of vehicle technology, and more specifically, to a vehicle projection method and a vehicle. Background Technology

[0002] With the development of automotive intelligence, the interconnection between mobile phones and vehicle systems has become a core scenario. Related in-vehicle wireless charging modules are mainly based on international standards for wireless power transmission and have charging status detection functions, but they can only display the charging status unidirectionally via indicator lights or the screen. Furthermore, in-vehicle screen mirroring technologies mostly rely on Wi-Fi hotspots or Bluetooth pairing. While wired screen mirroring offers high stability, it requires carrying cables. Wireless screen mirroring, on the other hand, requires users to sequentially turn on their phone's Wi-Fi, Bluetooth, and the vehicle's hotspot, completing multiple steps such as searching, pairing, and launching applications, which is complex and inefficient.

[0035] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0036] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0037] With the rapid development of automotive intelligence and connectivity, smart cockpits have become a core area for enhancing user experience, with the interconnection between mobile phones and vehicle systems being a key application scenario. Currently, in-vehicle wireless charging technology is mainly based on the Qi standard, an international standard for wireless power transmission that powers mobile devices through electromagnetic induction. Although this technology has been widely used to solve the problem of cable tangling, most related systems only provide one-way indication of charging status and do not integrate with other functions.

[0038] In terms of screen mirroring, the relevant technologies are mainly divided into wireless screen mirroring that relies on Wireless Fidelity (Wi-Fi) hotspots or Bluetooth pairing, and wired screen mirroring that connects via Universal Serial Bus (USB) / Type-C. While wireless screen mirroring is convenient, users need to sequentially turn on their phone's Wi-Fi, Bluetooth, and the car's hotspot, and complete multiple steps such as searching, pairing, and launching applications, which is cumbersome and time-consuming. Wired screen mirroring, on the other hand, has problems such as inconvenience in carrying around, safety hazards from plugging and unplugging, and the ease with which cables can be lost.

[0039] Furthermore, in relevant vehicle control architectures, wireless charging and screen mirroring functions typically operate independently, lacking a scenario-based coordination mechanism. While some systems offer one-click screen mirroring, users still need to manually trigger it, and it suffers from drawbacks such as hidden function entry points, high learning costs, forced pop-ups that interfere with users, and poor protocol compatibility, making it difficult to adapt to multiple brands of mobile phones. This results in redundancy and low efficiency for users in charging and connectivity scenarios.

[0040] According to an embodiment of this application, a method embodiment for vehicle screen projection is provided. It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions. Furthermore, although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in a different order than that shown here.

[0041] Figure 1 This is a schematic diagram of an optional vehicle projection system according to an embodiment of this application, such as... Figure 1 As shown, the system consists of components such as a wireless charging module, a central control screen module, a main controller, a user configuration unit, and auxiliary modules, aiming to achieve scenario-based functional linkage through software and hardware collaboration.

[0042] The wireless charging module, as the physical trigger layer, includes a charging coil that supports the international standard for wireless power transmission, a current detection unit and a temperature detection unit that integrate charging management and status detection functions. It is responsible for outputting 5-15W adjustable power to mobile devices and monitoring in real time whether a mobile phone is connected, whether the charging current is stable, and whether the charging temperature is normal to prevent overheating. The status signal is transmitted to the main controller through the Controller Area Network (CAN) bus.

[0043] The central control screen module includes touch screen hardware, display driver chip and touch feedback unit. Its software part integrates a screen projection protocol processing unit compatible with different mainstream protocols, a pop-up display control unit and a user interaction unit. It is responsible for receiving instructions from the main controller to display lightweight linkage pop-ups and receiving touch operation instructions from users.

[0044] The main controller (Microcontroller Unit, MCU) uses a high-performance system-on-chip (SoC) as the core control unit. It runs the linkage control logic unit, protocol stack management unit, and status judgment unit. It is responsible for receiving status signals from the wireless charging module to determine if the "stable charging" condition is met, querying the on / off status of the user configuration unit, sending pop-up commands to the central control screen, and automatically triggering a series of automated screen projection processes after user confirmation, including Wi-Fi Direct activation, Bluetooth pairing, protocol negotiation, and cloud authentication. Simultaneously, it monitors the screen projection status to handle abnormal disconnections. Wi-Fi Direct is a point-to-point wireless connection technology based on the Wi-Fi standard, allowing two devices, such as a mobile device and a vehicle's central control screen module, to establish a high-speed wireless connection directly without a traditional wireless access point, such as a home or office wireless router.

[0045] The user configuration unit is integrated into the vehicle system software, providing functions such as "charging-linked screen projection" switch, pop-up display duration setting, default screen projection application setting, and protocol priority setting. It allows users to customize the trigger conditions for linkage behavior, interface interaction details, and connection preferences, thereby ensuring that the charging function operates independently while realizing the on-demand automatic activation of the screen projection function.

[0046] In addition, the device also includes a Telematics Box (T-BOX) for cloud authentication, a Bluetooth module that supports fast pairing with multiple Bluetooth versions, and a Wi-Fi module that supports high-bandwidth transmission. Together, they form a complete smart cockpit interaction system that can achieve deep integration of wireless charging and screen projection without the need for additional hardware.

[0047] Figure 2 This is a flowchart of an optional vehicle screen projection method according to an embodiment of this application, such as... Figure 2 As shown, the process includes:

[0048] Step S21: In response to the mobile device enabling the wireless charging function inside the vehicle, obtain the charging current value of the mobile device.

[0049] Step S22: In response to the charging current value meeting the preset safety conditions, obtain the on / off status of the charging-linked screen projection function;

[0050] Step S23: In response to the switch being in the ON state, a pop-up control command is generated;

[0051] Step S24: Obtain the screen projection instruction corresponding to the pop-up control command;

[0052] Step S25: According to the screen projection instructions, control the vehicle's image display component to synchronously display the content displayed on the mobile device.

[0053] The aforementioned mobile device refers to a portable electronic device with wireless communication capabilities, which is portable and capable of data interaction or energy exchange with the vehicle's internal systems. In the embodiments of this application, the mobile device mainly includes smart terminals such as smartphones and tablets. These devices typically have a built-in battery, support Qi standard wireless charging reception, and integrate Bluetooth, Wi-Fi modules, and software stacks that support specific screen projection protocols. In vehicle usage scenarios, the mobile device is placed on the vehicle's wireless charging panel, obtains power through the wireless charging module, and synchronously displays its screen content through the vehicle's image display components, thereby realizing the linkage function of charging and interconnected screen projection.

[0054] The aforementioned wireless charging function refers to a power supply method based on electromagnetic induction or magnetic resonance principles, which provides power to mobile device batteries without the need for physical cable connections. Inside a vehicle, this is typically implemented by a wireless charging module integrated into the center console or armrest. This module includes a charging coil, a current detection unit, an induction control chip, and a temperature detection unit, used to output adjustable power to the mobile device and monitor the charging status in real time. During this process, the mobile device maintains physical contact or close coupling with the vehicle's wireless charging coil, achieving wireless energy transfer.

[0055] The charging current value mentioned above represents the electrical energy intensity flowing through the mobile device during the charging process. This value is collected in real time by the current detection unit with a specific accuracy, such as ±10mA. It is used to determine whether the mobile device is stably connected to the charging panel and whether the charging process is normal. It is a key physical signal that triggers subsequent linkage logic.

[0056] The aforementioned preset safety conditions represent a set of threshold criteria used to ensure a stable charging process and prevent accidental triggering. These typically include a charging current value greater than or equal to a specific threshold, such as 50mA, and a duration exceeding a set time, such as 1 second, and a charging temperature below a specific upper limit, such as 45°C. When the charging current value of the mobile device simultaneously meets the above current and temperature limits, it is considered to have met the preset safety conditions.

[0057] The aforementioned charging-linked screen projection function represents an intelligent interaction mode that combines wireless charging with in-vehicle screen projection connectivity. It allows users to control whether to trigger screen projection-related user interface feedback when stable charging is detected in the settings. The function's status is managed by the user configuration unit integrated into the vehicle's system settings, supporting enabling, disabling, and remembering the last setting. When the mobile device is in a stable charging state and the user turns on the linkage switch, the function will automatically trigger a screen projection prompt or initiate a screen projection connection; when this condition is no longer met, the function should stop operating or exit its current active state.

[0058] The above switch status indicates whether the charging-linked screen projection function is currently active or inactive. This status is stored in the user configuration unit. The main controller queries this status to determine whether to allow the execution of the automated linkage process from charging detection to pop-up display.

[0059] The aforementioned pop-up control command represents a data command sent by the main controller to the central control screen module to display a specific user interaction interface. This command includes information such as the pop-up's position coordinates, display duration, interface layout, and button configuration, and is used to present a lightweight, semi-transparent interactive window on the vehicle's image display component.

[0060] The aforementioned screen casting instruction indicates the user's response signal to the interactive window displayed in the pop-up control command through touch operation, such as "Confirm Screen Casting" or "Cancel Screen Casting". "Confirm Screen Casting" indicates that the user agrees to execute the subsequent screen casting connection process. After receiving the instruction, the main controller starts the automated protocol interaction.

[0061] The aforementioned image display component refers to the hardware device inside the vehicle used to display multimedia information and user interaction interface, such as a 10 to 15-inch central control screen. This component receives control signals from the main controller, is responsible for rendering pop-up interfaces, and finally synchronously displays the screen image from the mobile device, supporting screen scaling, rotation, and full-screen display adaptation.

[0062] The aforementioned displayed content refers to the screen interface of the mobile device and all the visual information contained therein. In this embodiment, the displayed content mainly includes the mobile device's operating system desktop, application interface, system status bar information, and user operation feedback interface. Specifically, the displayed content covers real-time images captured by the mobile device's camera, graphical user interfaces (GUIs) of pre-installed or third-party applications, text, images, video streams, and audio visualization interfaces, etc.

[0063] In this embodiment of the application, when projecting a screen onto a vehicle, the charging current value of the mobile device is obtained in response to the activation of the wireless charging function inside the vehicle. For example, when a user places the mobile device on the wireless charging panel inside the vehicle, the induction coil of the wireless charging module detects the presence of the mobile device and initiates the charging initialization process. The current detection unit monitors the current flowing through the mobile device in real time and transmits this value to the main controller to confirm that the mobile device has been physically connected and has entered the charging preparation or charging state.

[0064] In response to the charging current value meeting preset safety conditions, the on / off status of the charging-linked screen projection function is obtained. For example, the main controller receives the charging current value from the wireless charging module and compares it with preset current thresholds and duration requirements. If the current value is stable above the threshold and the duration meets the requirements, and the temperature detection unit confirms that the temperature is within the safe range, then the preset safety conditions are determined to be met. Subsequently, the main controller accesses the user configuration unit to read the current on / off status of the charging-linked screen projection function to determine whether to execute the linkage logic subsequently.

[0065] In response to the switch being turned on, a pop-up control command is generated. For example, after receiving a signal that the switch is turned on, the main controller further queries the user-preset pop-up display duration parameter, and generates a pop-up control command that includes the pop-up position, display content, and button layout based on the parameter and the preset interface template. The command is then sent to the central control screen module to prepare to display the screen projection selection interface to the user.

[0066] Obtain the screen casting instruction corresponding to the pop-up control command. For example, the central control screen module can display a lightweight semi-transparent pop-up on the image display component according to the pop-up control command. During the pop-up display, the user clicks a specific button, such as the "one-click screen casting" button, through touch operation. The central control screen module converts the touch event into a screen casting instruction signal and feeds it back to the main controller. After receiving the screen casting instruction, the main controller confirms that the user intends to perform the screen casting operation.

[0067] According to the screen projection instruction, the vehicle's image display component is controlled to synchronously display the content displayed on the mobile device. For example, upon receiving the screen projection instruction, the main controller automatically initiates an automated linkage process including enabling the Wi-Fi Direct channel, Bluetooth pairing, protocol identification, and cloud authentication. After the screen projection connection is successfully established, the main controller controls the image display component to receive video stream data from the mobile device and synchronously displays the mobile device's screen on the vehicle's image display component in real time, achieving screen mirroring or application streaming. The Wi-Fi Direct channel is the core communication link for achieving high-speed, stable, and wireless screen transmission in this embodiment of the application.

[0068] Based on the above steps S21 to S25, this application embodiment adopts a smart cockpit wireless charging and projection linkage control method. In response to the activation of the wireless charging function inside the vehicle by the mobile device, the charging current value of the mobile device is obtained. In response to the charging current value meeting the preset safety conditions, the on / off state of the charging linkage projection function is obtained. In response to the on / off state being enabled, a pop-up control command is generated. Then, the projection instruction corresponding to the pop-up control command is obtained. According to the projection instruction, the vehicle's image display component is controlled to synchronously display the display content of the mobile device. This achieves a deep binding between the physical triggering scenario of wireless charging and the interconnection requirement of projection. Through an automated process, the goal of full-link coordination from charging detection to projection connection is achieved. This simplifies the connection operation of in-vehicle projection and improves the efficiency of in-vehicle projection, thereby solving the technical problems of complex operation and low efficiency of in-vehicle projection methods in related technologies.

[0069] Optionally, the vehicle projection method further includes: obtaining the charging temperature of the mobile device; and determining that the charging current value meets the preset safety conditions in response to the charging current value being greater than or equal to a preset current threshold for a period of time exceeding a preset duration and the charging temperature being less than or equal to a preset temperature threshold.

[0070] The charging temperature mentioned above represents the thermodynamic temperature generated by the internal battery or charging circuit of the mobile device during the power transfer process via the wireless charging module. This value is collected in real time by the temperature detection unit integrated into the wireless charging module to monitor the thermal state of the mobile device during charging, preventing safety hazards or hardware damage caused by overheating.

[0071] The aforementioned preset current threshold represents the lower limit of current intensity used to determine whether a mobile device is stably connected to the wireless charging panel and enters a normal charging state. In this embodiment, the threshold is typically set to a specific value within the range of 50mA or 30-100mA, used to distinguish between instantaneous contact current caused by unstable placement of the mobile device and continuous, stable charging current.

[0072] The aforementioned preset duration represents the time criterion used to determine whether the charging current value remains stable. In this embodiment, the duration is typically set to 1 second or longer to filter out current fluctuations caused by shaking or poor contact during the placement of the mobile device, ensuring the stability of the triggering conditions.

[0073] The aforementioned preset temperature threshold represents the upper limit of temperature used to determine whether the charging process of a mobile device is within a safe temperature range. In this embodiment, the threshold is typically set to 45°C to prevent the mobile device from overheating due to poor heat dissipation or high ambient temperature during charging, thereby ensuring the safety of the user and the device.

[0074] In this embodiment of the application, when determining whether the charging current value meets the preset safety conditions, the charging temperature of the mobile device is first obtained. For example, the wireless charging module uses a built-in temperature sensor or sensing control chip to monitor and collect the temperature data of the mobile device during the charging process in real time, and transmits this temperature data to the main controller.

[0075] In response to a situation where the charging current value is greater than or equal to a preset current threshold for a duration exceeding a preset duration, and the charging temperature is less than or equal to a preset temperature threshold, the main controller determines that the charging current value meets preset safety conditions. For example, the main controller receives charging current and charging temperature data from the wireless charging module, compares the charging current value with the preset current threshold, and calculates the duration for which the charging current value remains greater than or equal to the preset current threshold. This calculation is then compared to a preset duration, and the charging temperature is compared to a preset temperature threshold. When the duration of the charging current value exceeds the preset duration and the charging temperature is less than or equal to the preset temperature threshold, the main controller determines that the charging current value meets the preset safety conditions.

[0076] Based on the above optional embodiments, this application embodiment obtains the charging temperature of the mobile device, and when the charging current value is greater than or equal to a preset current threshold for a period of time exceeding a preset duration, and the charging temperature is less than or equal to a preset temperature threshold, it determines that the charging current value meets the preset safety conditions. This can accurately distinguish between the stable charging state and the abnormal state of the mobile device, avoid false triggering caused by unstable placement of the phone or abnormal charging, and thus ensure that the subsequent screen projection linkage process is triggered only when the mobile device is in a safe and stable charging state, thereby improving the accuracy and safety of wireless charging and screen projection linkage control.

[0077] Optionally, obtaining the on / off status of the charging-linked screen projection function includes: generating a stable charging signal for the mobile device in response to the charging current value meeting preset safety conditions; and obtaining the on / off status of the charging-linked screen projection function based on the stable charging signal.

[0078] The aforementioned stable charging signal is a status indication signal generated by the wireless charging module or main controller. It is used to clearly communicate to other modules in the system that the mobile device is currently in a stable charging state that meets preset safety conditions. This signal serves as the direct basis for triggering subsequent permission checks and pop-up displays, ensuring that the linkage process only starts when the physical connection is stable and secure.

[0079] In this embodiment, when acquiring the on / off state of the charging-linked screen projection function, a stable charging signal for the mobile device is generated in response to the charging current value meeting preset safety conditions. For example, after receiving the charging current value and charging temperature data reported by the wireless charging module, and confirming through logical judgment that these data meet the preset safety conditions (i.e., stable current and normal temperature), the main controller sends a "stable charging" status notification signal to other modules within the system. This action serves as a bridge, transforming the physical charging state into a system-level control signal.

[0080] Based on a stable charging signal, the on / off status of the charging-linked screen projection function is obtained. For example, upon receiving a stable charging signal, the main controller immediately accesses the user configuration unit, reads the current setting value for the "charging-linked screen projection" function (whether it's on or off), and determines whether to execute the subsequent pop-up window and screen projection process. This action decouples physical triggering from user permission control, ensuring that the initiation of the linkage operation conforms to both the physical scenario and the user's wishes.

[0081] Based on the above optional embodiments, this application embodiment obtains the on / off state of the charging-linked screen projection function, including generating a stable charging signal for the mobile device in response to the charging current value meeting preset safety conditions, and obtaining the on / off state of the charging-linked screen projection function based on the stable charging signal. This ensures that permission queries for the linkage function are only performed when the mobile device is in a real and stable charging state, effectively avoiding false triggering caused by unstable phone placement, poor contact, or abnormal charging. At the same time, by independently obtaining the on / off state, the user's control over their personalized settings is guaranteed, improving the accuracy of linkage control and the flexibility of user experience.

[0082] Optionally, generating pop-up control instructions includes: obtaining a preset pop-up display duration and preset display content; and generating pop-up control instructions based on the pop-up display duration and preset display content.

[0083] The aforementioned pop-up display duration refers to the length of time the linked pop-up is continuously displayed on the central control screen module. In this embodiment, this duration is determined by the "Pop-up Display Duration Setting" parameter in the user configuration unit, with selectable values ​​including 2 seconds, 3 seconds, or 5 seconds, and a default value of 3 seconds. This feature provides user-customizable flexibility, allowing users to adjust the pop-up display time according to driving environment and operating habits.

[0084] The aforementioned preset display content represents the specific interface elements and information displayed on the central control screen module by the linked pop-up window. In this embodiment, the preset display content includes the title "One-Click Casting," the prompt "Phone is charging, want to cast quickly?", the function buttons "One-Click Casting," "Cancel," and an optional "Don't remind me again" checkbox. "One-Click Casting" has a green background with a casting icon, while "Cancel" has a gray background with a close icon. This feature simplifies the complex casting connection logic into an intuitive graphical interface and guides users to make quick decisions by differentiating operation options through color.

[0085] In this embodiment, when generating pop-up control commands, the preset pop-up display duration and preset display content are first obtained. For example, before generating the pop-up control commands, the main controller reads the user-saved pop-up display duration parameter from the user configuration unit and calls a built-in or user-defined pop-up display content template. This step ensures that the pop-up display characteristics conform to the user's personalized settings, achieving a personalized interactive experience.

[0086] Then, based on the pop-up display duration and preset display content, a pop-up control command is generated. For example, the main controller combines the read pop-up display duration parameter and preset display content information into a specific data structure or command format to form a pop-up control command used to drive the central control screen module to display the pop-up. This action acts as a bridge connecting user settings and interface execution, ensuring that the central control screen module can accurately receive and execute the correct display tasks.

[0087] Based on the above optional embodiments, this application embodiment generates pop-up control instructions, including obtaining the preset pop-up display duration and preset display content, and generating pop-up control instructions based on the pop-up display duration and preset display content. This ensures that the display time, interface layout, and interactive elements of the linked pop-up all conform to the user's personalized presets, avoids interference from forced pop-ups, improves the user's sense of control and satisfaction with the vehicle system, and improves the efficiency and accuracy of the central control screen module display control through a standardized instruction generation mechanism.

[0088] Optionally, obtaining the projection instruction corresponding to the pop-up control command includes: generating a projection inquiry pop-up in the preset display area of ​​the image display component based on the pop-up control command; and obtaining the projection instruction through the projection inquiry pop-up.

[0089] The aforementioned preset display area refers to a predefined specific location area on the image display component used to display the linked pop-up window. In this embodiment, this area is typically located in the lower right corner of the screen or a user-customizable location, with a size of approximately 8cm × 4cm, and is designed to be semi-transparent to ensure that it does not obstruct key driving information such as vehicle speed and navigation.

[0090] The aforementioned screen mirroring prompt pop-up is a user interface element generated in the preset display area of ​​the image display component based on pop-up control commands, used to ask the user whether to perform a screen mirroring operation. This pop-up can display preset content.

[0091] In this embodiment, when obtaining the projection instruction corresponding to the pop-up control command, a projection inquiry pop-up is first generated in the preset display area of ​​the image display component based on the pop-up control command. For example, the central control screen module receives the pop-up control command sent by the main controller, parses the parameters in the command, such as location, content, and duration, and renders a projection inquiry interface containing a title, prompts, and function buttons in the preset display area of ​​the image display component. This action transforms the abstract control command into a visual user interface, providing an entry point for subsequent user interaction.

[0092] and then obtain a screen projection instruction through a screen projection inquiry pop-up window. For example, the user touches a specific button in the screen projection inquiry pop-up window on the touch screen, such as "One-tap Screen Projection" or "Cancel", the touch feedback unit of the image display component detects a touch event and converts it into a corresponding screen projection instruction, such as "Screen Projection Confirmation" or "Cancel", which is finally transmitted to the main controller. This action completes the conversion from user intention to system instruction, and is a key link for the linkage process to continue executing or terminate.

[0093] Based on the above optional embodiments, the embodiments of the present application obtain the screen projection instruction corresponding to the pop-up window control instruction, including generating a screen projection inquiry pop-up window in the preset display area of the image display component based on the pop-up window control instruction, and obtaining the screen projection instruction through the screen projection inquiry pop-up window, which can ensure that the display position and content of the linkage pop-up window conform to the preset safety and interaction specifications, and guide the user to make quick decisions through an intuitive graphical interface, which not only avoids the interference of forced pop-up windows on driving attention, but also ensures the accurate transmission of the user's operation intention, and improves the accuracy of screen projection linkage control and the friendliness of user experience.

[0094] Optionally, controlling the image display component of the vehicle to synchronously display the display content of the mobile device according to the screen projection instruction includes: enabling a preset dedicated screen projection channel and sending a Bluetooth pairing request to the mobile device based on the screen projection instruction, where the preset dedicated screen projection channel is used for data transmission, and the Bluetooth pairing request is used for identity recognition of the mobile device; acquiring a screen projection protocol of the mobile device; and in response to the Bluetooth pairing request being approved, controlling the image display component to synchronously display the display content of the mobile device according to the preset dedicated screen projection channel and the screen projection protocol.

[0095] The above-mentioned preset dedicated screen projection channel refers to a high-speed wireless communication link enabled by the vehicle Wi-Fi module for carrying the screen mirroring data stream of the mobile device. In the embodiments of the present application, this channel is usually established based on Wi-Fi Direct technology, the Service Set Identifier (SSID) is "vehicle machine name + dedicated for screen projection", and the transmission rate is ≥500Mbps. The preset dedicated screen projection channel enables users to realize high-bandwidth and low-latency data transmission through the dedicated channel without manually searching for and connecting to public Wi-Fi hotspots.

[0096] The above-mentioned Bluetooth pairing request refers to a control signal sent by the vehicle Bluetooth module for preliminary identity recognition and key exchange with the mobile device. In the embodiments of the present application, this request is automatically sent based on the Bluetooth Media Access Control Address (MAC) of the mobile phone detected by the wireless charging module, without requiring the user to manually search for the device.

[0097] The aforementioned screen mirroring protocol refers to the communication specifications used to define the screen mirroring transmission format, control commands, and data encapsulation standards between mobile devices and the vehicle's central control screen. In the embodiments of this application, the screen mirroring protocol includes, but is not limited to, mainstream protocols such as AirPlay, Miracast, CarWith, or HiCar, which are automatically identified by the screen mirroring protocol processing unit.

[0098] In this embodiment, when controlling the vehicle's image display component to synchronously display the mobile device's content according to the screen projection instruction, the system first activates a preset dedicated screen projection channel and sends a Bluetooth pairing request to the mobile device. The preset dedicated screen projection channel is used for data transmission, and the Bluetooth pairing request is used for mobile device identification. For example, after receiving a screen projection instruction confirming the user's confirmation, the main controller controls the Wi-Fi module to activate a dedicated data channel and simultaneously controls the Bluetooth module to send an identification request to the mobile device. This action, based on the physical connection (charging), further establishes a logical connection—a wireless data link—preparing for subsequent image transmission and achieving automated conversion from user intent to system resource allocation.

[0099] Secondly, the screen mirroring protocol of the mobile device is obtained. For example, the main controller sends a protocol negotiation request to the mobile device via Bluetooth or a dedicated screen mirroring channel, and receives the screen mirroring type identifier returned by the mobile device. This action aims to determine the communication standards supported by both parties, so as to select the optimal transmission protocol for subsequent screen synchronization and ensure the correct decoding and display of the mirrored content.

[0100] Finally, in response to a successful Bluetooth pairing request, the image display component is controlled to synchronously display the mobile device's content according to a preset dedicated projection channel and projection protocol. For example, after confirming successful mobile device identification, the main controller receives the mobile device's screen data stream through a preset dedicated projection channel according to the established projection protocol, decodes the data stream, and renders it to the image display component. This action completes the entire process from data reception to final visualization, achieving real-time, synchronous mirroring of the mobile device's interface on the vehicle's infotainment screen.

[0101] Based on the above optional embodiments, this application embodiment controls the vehicle's image display component to synchronously display the mobile device's display content according to the screen projection instruction. This includes opening a preset dedicated screen projection channel and sending a Bluetooth pairing request to the mobile device based on the screen projection instruction, obtaining the mobile device's screen projection protocol, and responding to the successful Bluetooth pairing request by controlling the image display component to synchronously display the mobile device's display content according to the preset dedicated screen projection channel and screen projection protocol. This can automatically complete the entire process from identity recognition and protocol negotiation to data synchronization without requiring any manual connection operation from the user. This significantly shortens the screen projection establishment time, improves the stability and compatibility of the connection, and achieves an efficient and seamless vehicle-machine interconnection experience.

[0102] Optionally, the vehicle screen projection method also includes: in response to the mobile device pausing the wireless charging function, exiting the charging-linked screen projection function.

[0103] The aforementioned exit from the charging-linked screen mirroring function refers to the process by which the main controller, upon detecting that the mobile device is no longer charging, terminates the ongoing screen mirroring connection session and releases relevant system resources, such as releasing the Wi-Fi Direct channel and Bluetooth pairing session. This process ensures that the vehicle system does not maintain unnecessary background connections when the mobile device is no longer in a charging environment, thereby saving energy and avoiding resource consumption.

[0104] In this embodiment, the charging-linked screen projection function exits when the mobile device suspends its wireless charging function. For example, the main controller continuously monitors the status signals of the wireless charging module. When it receives a signal indicating that charging has stopped, charging has been interrupted, or the mobile device has been moved (i.e., the mobile device has suspended its wireless charging function), the main controller immediately terminates the screen projection connection, disconnects the data transmission link, and restores the display interface to its default state. This action physically decouples the charging and screen projection scenarios, ensuring consistency between functional operation and the user's actual usage scenario.

[0105] Based on the above optional embodiments, this application embodiment, by responding to the mobile device pausing the wireless charging function and exiting the charging-linked screen projection function, can ensure that the screen projection function remains active only when the mobile device is charging in the specific physical scenario. Once the charging connection is disconnected, the screen projection state is automatically deactivated, avoiding the waste of system resources and potential interference caused by maintaining an invalid connection when the mobile device leaves the vehicle or after charging is completed, thereby improving the resource management efficiency and scenario adaptability of the vehicle's intelligent cockpit system.

[0106] Optionally, the vehicle screen projection method also includes: controlling the mobile device to charge in response to the switch being off.

[0107] The aforementioned control of mobile device charging refers to the process where, when the main controller determines that the linkage function is not enabled, it directly sends a start or maintain power supply command to the wireless charging module, causing the wireless charging module to transfer power to the mobile device through electromagnetic induction. This action ensures that the core charging needs of the mobile device are still met even after the user disables the linkage screen mirroring function, and this process operates independently of the screen mirroring logic.

[0108] In this embodiment, the mobile device is controlled to charge when the switch is in the "off" state. For example, after receiving a signal from the user configuration unit that the "charging-linked screen projection" switch is "off," the main controller ignores the subsequent screen projection pop-up generation and screen projection connection process, and directly executes the wireless charging power supply program to maintain or begin replenishing the mobile device's power. This process decouples the charging function from the screen projection function, ensuring that when the linkage function is off, the charging service is not hindered or affected by any screen projection-related logic, thus guaranteeing the continuity and reliability of the basic charging service.

[0109] Based on the above optional embodiments, this application embodiment controls the mobile device to charge in response to the switch state being closed. When the user explicitly disables the charging-linked screen projection function, it ensures that the charging process of the mobile device is not interfered with by any screen projection logic. This realizes the independent operation of the charging function and the screen projection function, which not only meets the user's needs for basic charging services, but also avoids the experience fragmentation caused by forced linkage or invalid pop-ups, and improves the flexibility of function control and the stability of system operation.

[0110] Optionally, the vehicle projection method also includes: in response to the charging current value not meeting the preset safety conditions, displaying a charging abnormality prompt in a preset display area of ​​the image display component.

[0111] The aforementioned charging anomaly alert is a visual feedback message generated in a preset display area of ​​the image display component when the charging status is detected to be inconsistent with preset safety conditions. This alert aims to inform the user that there is an abnormality in the current charging process, such as improper phone placement, instability, or excessive temperature.

[0112] In this embodiment, when the charging current value fails to meet a preset safety condition, a charging abnormality warning is displayed in a preset display area of ​​the image display component. For example, when the main controller detects that the current or temperature value reported by the wireless charging module does not meet the preset safety condition (e.g., the current is unstable, the threshold is not reached, or the temperature is too high), it sends a command to the image display component to render and display the charging abnormality warning text or icon in the preset display area. This process provides visual feedback on the fault status, guiding the user to perform corrective actions.

[0113] Based on the above optional embodiments, this application embodiment displays a charging abnormality prompt in a preset display area of ​​the image display component in response to the charging current value not meeting the preset safety conditions. This can promptly provide feedback to the user on physical abnormalities during the wireless charging process, avoiding accidental triggering of the screen projection linkage process under poor contact or abnormal conditions. At the same time, it guides the user to adjust the phone position or check the charging environment through clear visual prompts, thereby improving the safety of the charging process and the accuracy of user operation.

[0114] For example, taking a mobile device compatible with protocol A as an example, the vehicle screen projection method of this application embodiment is described. Specifically, the user enables the "Charging Linkage Screen Projection" function in the vehicle settings and specifies the default projection application as application A. Subsequently, the user places the mobile device supporting protocol A on the wireless charging panel. The wireless charging module monitors the charging status in real time. When a stable current is detected and the temperature is within a safe range for a predetermined time, it sends a "Stable Charging" trigger signal to the main controller. The main controller verifies that the linkage switch has been turned on, and then instructs the central control screen to display a lightweight semi-transparent pop-up window containing "One-Click Screen Projection", "Cancel", and "Don't Prompt Again" options at a designated position on the screen, such as the lower right corner. After the user clicks "One-Click Screen Projection" to confirm, the main controller starts the automated process, controls the wireless module to open a dedicated screen projection channel, and uses the Bluetooth module to automatically initiate a pairing request based on the detected mobile device identifier. After the mobile device completes the connection, the screen projection protocol processing unit automatically recognizes protocol A and completes cloud authentication through the vehicle networking module. After successful authentication, screen projection is successfully established, and the image display component automatically displays the user-preset application A interface in full screen without any obvious delay or lag. When the user removes the mobile device, causing charging to be interrupted, the wireless charging module sends a charging stop signal, and the main controller automatically disconnects the screen projection connection and displays a disconnection prompt, thus realizing the fully automated operation from placing the mobile device, pop-up confirmation to automatic screen projection and disconnection.

[0115] For example, taking a mobile device compatible with the B protocol as an example, the vehicle screen projection method of this application embodiment is described. In this mobile device, a protocol priority setting function is introduced, allowing the user to specify the priority of using the B protocol. Specifically, the user enables the "Charging-Linked Screen Projection" function in the vehicle settings and sets the protocol priority to "B". Subsequently, the user places the B protocol-compatible B mobile device on the wireless charging panel. After the wireless charging module detects that the charging current is stable and the temperature is normal, it sends a "Stable Charging" trigger signal to the main controller. The main controller confirms that the linkage switch is in the on state, and then instructs the central control screen to pop up a linkage pop-up window containing options such as "One-Click Screen Projection". After the user clicks "One-Click Screen Projection", the main controller starts the automated process, opens a dedicated screen projection channel through the wireless module, and automatically initiates a pairing request using the Bluetooth module. The screen projection protocol processing unit identifies the B protocol supported by the mobile phone according to the user's preset priority and completes the cloud authentication process unique to the B protocol through the vehicle networking module. After successful authentication, the screen projection connection is quickly established, the image display component automatically launches the user's preset B application, displays the B application screen in full screen synchronously, and supports operations such as zooming via voice commands. This embodiment achieves faster connection speeds and richer functional interactions through protocol optimization for B mobile devices, thereby improving the user experience for a specific user group.

[0116] Figure 3 This is a schematic diagram of an optional vehicle screen projection method according to an embodiment of this application, such as... Figure 3 As shown, it mainly covers the core stages such as initialization, charging status detection, linkage permission judgment, pop-up display, one-click screen casting execution and cancellation. First, in the vehicle power-on initialization stage, the main controller, wireless charging module and central control screen module complete self-tests and load preset parameters such as linkage switch status, pop-up duration and default screen casting application saved in the user configuration unit, and at the same time establish the screen casting protocol stack ready state.

[0117] Then, the charging status detection phase begins. When the user places the phone on the wireless charging panel, the wireless charging module detects the charging current. If the current is stable at the threshold and lasts for ≥1 second, and the temperature is normal, it sends a "stable charging" trigger signal to the main controller. If an abnormality is detected, it only indicates a charging fault and does not trigger any linkage.

[0118] After the main controller receives the "stable charging" signal, it enters the linkage permission judgment stage, checking the "charging linkage screen projection" switch status in the user configuration unit: if the switch is off, charging continues normally and no further operation is performed; if the switch is on, a pop-up control command is sent to the central control screen according to the preset pop-up duration. Then, the central control screen module displays a lightweight linkage pop-up window at a designated location on the screen, such as the lower right corner, containing screen projection prompts and operation buttons such as "one-click screen projection," "cancel," or "don't remind again." If the user does not operate within the set time, the pop-up window disappears automatically.

[0119] When the user clicks "One-click screen mirroring", the main controller starts the automated linkage process, which sequentially controls the Wi-Fi module to open a dedicated screen mirroring channel, the Bluetooth module to automatically pair based on the phone's MAC address, the screen mirroring protocol processing unit to automatically identify and negotiate the protocol, and completes cloud authentication through the T-BOX module, ultimately realizing the synchronous display of the phone screen content to the central control screen and automatically launching the preset default application.

[0120] If the user chooses to cancel or the pop-up timeout occurs, the process terminates; if "Don't remind me again" is checked, the system automatically turns off the linkage switch. Throughout the screen mirroring process, the main controller monitors the connection status in real time. Once it detects that the phone has been removed or the signal has been interrupted, it automatically disconnects the screen mirroring and notifies the user.
