Description

Technical Field

[0001] This invention relates to the field of in-vehicle infotainment systems, and in particular to an internet-based entertainment system. Background Technology

[0002] With the rapid development of the smartphone ecosystem, in-vehicle infotainment (IVI) systems are increasingly integrating with mobile devices. Mainstream connectivity methods include Apple's CarPlay and Android Auto, both of which project the mobile device's application ecosystem, media resources, and user interface onto the vehicle's central control screen via data cable or wirelessly, enabling functions such as navigation, music playback, and voice interaction. However, existing in-vehicle systems still have the following shortcomings in connected entertainment: most current systems only offer a single brightness adjustment option, failing to automatically match appropriate brightness based on the vehicle's parking light status (e.g., daytime running lights being on) or the interface background mode. This results in excessive brightness at night affecting driving safety, or insufficient brightness during the day affecting visibility. Furthermore, user-defined brightness settings cannot establish a one-to-one correspondence with different scenarios, requiring frequent manual adjustments and leading to a poor user experience.

[0003] After connecting via CarPlay or Android Auto, system status information is scattered across different interfaces or sub-menus, making it difficult for users to promptly grasp key parameters such as the current connectivity status, media volume, and vehicle alert volume, and lacking a real-time synchronization mechanism. Existing in-vehicle infotainment systems typically use independent control logic for adjusting alert and media volumes, with unclear distinctions between sliders, physical buttons, or pop-up interfaces. In a connected ecosystem, the volume adjustment mechanisms on the mobile app and the in-vehicle infotainment system differ, easily leading to user errors or sudden volume changes. Most in-vehicle infotainment systems fail to automatically restore the user's brightness or volume settings from the previous scenario after power-on, based on the current parking light status and background mode. This forces users to readjust parameters when entering different driving environments, such as daytime or nighttime, reducing the in-vehicle infotainment system's intelligence.

[0004] In summary, existing technologies urgently need a vehicle entertainment control method that can integrate the mobile phone interconnection ecosystem, provide intelligent brightness linkage, unified volume control and system status visualization, and have scene memory capabilities, in order to improve the consistency of interaction and user experience during driving. Summary of the Invention

[0005] In view of the above-mentioned problems, the present invention is proposed.

[0006] Therefore, the problem to be solved by the present invention is to address the issues of unintelligent brightness adjustment, scattered and asynchronous volume control, inconsistent presentation of system status information, and lack of contextualized settings restoration after power-on in existing in-vehicle systems in mobile terminal interconnection scenarios.

[0007] To solve the above-mentioned technical problems, the present invention provides the following technical solution: In a first aspect, embodiments of the present invention provide an interconnected entertainment system, comprising: an interconnection access module, configured to acquire the interconnection connection status between the vehicle host and an external mobile device; when the mobile device is detected to be an iOS device, establishing a CarPlay interconnection channel and loading an iOS ecosystem application interface; when the mobile device is detected to be an Android device, establishing an Android Auto interconnection channel and loading an Android ecosystem application interface; The initial brightness configuration module is used to obtain the vehicle's low-light status and interface background mode based on the brightness control mechanism of the vehicle host, and call the preset initial brightness value according to the combination of low-light on / off and dark and light modes, and present the brightness adjustment range in the form of a percentage slider. The brightness linkage adjustment module is used to monitor the user's click or slide command on the slider on the central control display screen, adjust the current interface brightness according to the user input, and update the brightness percentage display in real time; when the status of the small light or the background mode changes, the brightness recalculation logic is automatically triggered. The brightness configuration memory module is used to write the user's brightness setting value under the combination of each small light state and background mode into the user configuration memory space of the vehicle host during the brightness adjustment process; after the vehicle is powered on again, it reads the corresponding historical brightness value according to the current small light state and background mode; if there is no historical setting, it loads the initial brightness default value of the corresponding scene. The volume control module is used to monitor the user's interactive operations on the central control display screen, identify adjustment commands for vehicle prompt tone volume and media volume, then complete the setting of volume parameters, and feed back the adjusted status information in the output path; The status display module is used to obtain the current operating status, interconnection channel status, volume parameters, and brightness parameters through the vehicle's built-in information components, and present them in real time in a visual manner.

[0008] As a preferred embodiment of the interconnected entertainment system described in this invention, the following includes: recalling a preset initial brightness value and presenting the brightness adjustment range as a percentage slider, including: The vehicle host searches for the corresponding initial brightness reference value in a preset table based on the combination of the vehicle's low-light status and the interface background mode. The brightness adjustment is presented on the central control display screen using a slider control. The slider displays the current brightness percentage value and supports two operations: finger dragging and clicking for fine adjustment. The adjustment precision of the slider is 1%. The brightness setting triggered by each slide or click by the user is updated in 1% increments, and the updated percentage is mapped to the physical backlight in real time. The percentage mapping adopts a configurable mapping curve, which includes linear mapping and non-linear mapping.

[0009] As a preferred embodiment of the interconnected entertainment system described in this invention, the system further includes: displaying a preset initial brightness value and a brightness adjustment range as a percentage slider; and also includes: When the light status or background mode changes, the host calls the preset brightness benchmark of the corresponding scene and gradually changes the current brightness according to the set smooth transition strategy, while updating the percentage position of the slider to the target percentage. The preset table, mapping curve, and smooth transition parameters are stored in the vehicle host's non-volatile memory and loaded when the system starts. If no historical user settings are obtained, the default initial value for the corresponding scenario is returned according to the preset table.

[0010] As a preferred embodiment of the interconnected entertainment system described in this invention, when the status of the indicator light or the background mode changes, brightness recalculation logic is automatically triggered, including: The vehicle's main unit detects that the status of the small lights changes from on to off, or from off to on, or that the background mode changes from dark to light, or from light to dark. In response to the detection, the host obtains a preset initial brightness percentage value corresponding to the new "light status × background mode" combination from the preset brightness table; The host takes the current display brightness percentage as the initial state and the target brightness percentage as the final state. It calculates the transition curve according to the preset brightness transition strategy and controls the backlight or panel brightness drive according to the transition curve to make the interface brightness smoothly transition to the target brightness. Once the transition is complete, the target percentage is used as the current brightness percentage and saved in the memory storage space corresponding to the current "light status × background mode" combination.

[0011] As a preferred embodiment of the interconnected entertainment system described in this invention, after the vehicle is powered back on, the corresponding historical brightness value is read according to the current parking light status and background mode, including: During the system power-on initialization process, the vehicle host obtains the current status of the vehicle's parking lights and the interface background mode, and combines them to form a target scene identifier. The host accesses the brightness setting index table stored in the user preference memory module and queries the corresponding historical brightness percentage value based on the target scene identifier; If a valid historical brightness value is found, the historical brightness percentage is used as the initialization parameter for the current brightness, and the panel backlight is directly set to the corresponding brightness. At the same time, the brightness slider is updated to the historical percentage position. If no historical value is found or the historical value is empty, the default initial brightness corresponding to the target scene in the preset brightness table is loaded, and the panel brightness and slider display are set accordingly. After the brightness is restored, the brightness status is written into the system running status information of this startup.

[0012] As a preferred embodiment of the interconnected entertainment system described in this invention, if no historical settings exist, the initial brightness default value for the corresponding scene is loaded, including: The vehicle host accesses a preset brightness table to obtain the initial brightness default value for the scene based on the current status of the small lights and the background mode combination. The initial brightness default value is stored in the form of a percentage. The initial brightness default value is used as the brightness start parameter for this scene to directly drive the panel backlight or display module to output the corresponding physical brightness. The brightness slider control is synchronously updated to the percentage position corresponding to the initial brightness default value, so that the UI display is consistent with the actual brightness; the default brightness value is marked as "system default value loading record" and written to the brightness status log; when the user adjusts the brightness in the current scene, the user-adjusted brightness value is overwritten and replaced with the default brightness value.

[0013] As a preferred embodiment of the interconnected entertainment system described in this invention, the system includes: monitoring user interactions on the central control display screen, identifying adjustment commands for vehicle alert volume and media volume, and then setting volume parameters, including: The vehicle-mounted host monitors user interaction operations on the central control display screen, including dragging the volume slider, clicking the increase / decrease buttons, or touching a specified volume area. The host analyzes the detected touch behavior, identifies the volume type corresponding to the operation as either a notification sound volume or a media volume, and generates a corresponding volume adjustment command, which is expressed in the form of a percentage value or discrete increments. The vehicle audio management module is invoked according to the volume adjustment command to adjust the output gain parameter of the corresponding audio source channel so that the volume of the prompt tone channel or media audio channel is updated to the target volume level according to the command. After the volume parameter setting is completed, the actual set volume percentage value is sent back to the interface display module in real time, and the corresponding slider or numerical display area is updated.

[0014] As a preferred embodiment of the interconnected entertainment system described in this invention, the system acquires the current operating status, interconnection channel status, volume parameters, and brightness parameters through the vehicle's built-in information components and presents them visually in real time, including: The collected operating status, interconnection status, and volume and brightness parameters are formatted according to a preset data structure to generate a visual data frame. The displayed data frame is sent to the central control display module, and is displayed in real time on the interface in the form of icons, text parameters, percentage sliders or status indicator lights.

[0015] In a second aspect, embodiments of the present invention provide a computer device, including a memory and a processor, wherein the memory stores a computer program, wherein the computer program instructions, when executed by the processor, implement the steps of an interconnect-based entertainment system as described in the first aspect of the present invention.

[0016] Thirdly, embodiments of the present invention provide a computer-readable storage medium having a computer program stored thereon, wherein: when the computer program instructions are executed by a processor, they implement the steps of an interconnected entertainment system as described in the first aspect of the present invention.

[0017] The beneficial effects of this invention are as follows: By constructing a brightness-volume adaptive control mechanism for the vehicle's human-machine interface based on the status of parking lights, background mode, and historical preferences, this invention can automatically perform brightness recalculation, historical parameter backtracking, and default value loading during vehicle power-on / off, scene switching, and user interaction, thereby achieving intelligent and personalized adjustment of the brightness and volume of the vehicle's infotainment interface. This invention not only reduces repetitive setting operations for users and improves the comfort of vehicle use and the human-machine interaction experience, but also improves the responsiveness and environmental adaptability of brightness and volume control.

[0019] Figure 1 This is a schematic diagram of the system structure of the present invention. Detailed Implementation

[0020] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0022] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments. Example

[0023] Reference Figure 1 This is the first embodiment of the present invention. This embodiment provides an internet-based entertainment system, which consists of an internet access module, a brightness initial configuration module, a brightness linkage adjustment module, a brightness configuration memory module, a volume control module, and a status display module.

[0024] Specifically, the interconnection access module is used to obtain the interconnection connection status between the vehicle host and external mobile devices. When the mobile device is detected as an iOS device, a CarPlay interconnection channel is established and the iOS ecosystem application interface is loaded; when the mobile device is detected as an Android device, an Android Auto interconnection channel is established and the Android ecosystem application interface is loaded.

[0025] Specifically, the initial brightness configuration module is used to obtain the vehicle's parking light status and interface background mode based on the brightness control mechanism of the vehicle host, and call the preset initial brightness value according to the combination of parking light on / off and dark / light modes, presenting the brightness adjustment range in the form of a percentage slider.

[0026] Furthermore, the vehicle host searches for the corresponding initial brightness reference value in a preset table based on the combination of the vehicle's low-light status and the interface background mode. The brightness adjustment is presented on the central control display screen using a slider control. The slider displays the current brightness percentage value and supports two operations: finger dragging and clicking for fine adjustment. The adjustment precision of the slider is 1%. The brightness setting triggered by each slide or click by the user is updated in 1% increments, and the updated percentage is mapped to the physical backlight in real time. The percentage mapping adopts a configurable mapping curve, which includes linear mapping and non-linear mapping.

[0027] Furthermore, when the light state or background mode changes, the host calls the preset brightness benchmark of the corresponding scene and gradually changes the current brightness according to the set smooth transition strategy, while updating the percentage position of the slider to the target percentage. The preset table, mapping curve, and smooth transition parameters are stored in the vehicle host's non-volatile memory and loaded when the system starts. If no historical user settings are obtained, the default initial value for the corresponding scenario is returned according to the preset table.

[0028] For example, after the vehicle is powered on, the onboard unit first reads the current status of the vehicle's parking lights (ON / OFF) and the interface background mode (light / dark), and uses these two as a combination key to look up the value in a preset brightness table. For instance, in the scenario of parking lights being off and in light mode, the system retrieves an initial baseline brightness value of 72%.

[0029] Based on this baseline value, the host computer displays the brightness adjustment range as a percentage slider in the settings interface of the central control screen. The slider display area shows "72%" in real time and supports two adjustment methods: finger drag: the user can drag the slider along the track, and the brightness setting is updated every 1% step; single click fine adjustment: the user clicks anywhere on the slider track, and the system calculates the corresponding percentage based on the click location and adjusts the current position of the slider with a precision of 1%. When the user performs an adjustment operation on the slider, the host computer converts the percentage value into the physical backlight level in real time according to the configured brightness mapping curve. In this embodiment, both linear and non-linear mapping are supported. Users can select different curves in engineering mode to adapt to the display style of different screen hardware.

[0030] When the driver turns on the parking lights while the vehicle is in motion, the system detects the change from OFF to ON. The host computer retrieves the baseline brightness value for "parking lights on + dark mode" from a preset table, for example, 38%. To avoid glare or discomfort caused by sudden brightness changes, the system performs a gradual transition according to a pre-defined brightness transition strategy. In this embodiment, the smooth transition time is set to 300 ms. The host computer interpolates the intermediate brightness value using a fixed refresh cycle, causing the screen brightness to smoothly decrease from 72% to 38%. Simultaneously, the brightness slider on the central control display automatically updates, and its slider position moves synchronously to "38%" to ensure that the interface display matches the actual brightness without requiring manual confirmation from the user. When the vehicle is powered back on, the onboard host first reads the vehicle's current parking light status and interface mode, for example, "parking lights off + light mode". The host then attempts to retrieve the most recently set historical brightness value for this scenario from non-volatile memory. If a historical value exists, such as when the user last set the brightness to 65% in this scenario, the system will automatically load that value and display it as "65%" on the slider. If no historical setting exists (e.g., first-time use, uninitialized storage, or data loss), the system will load the default initial brightness value for this scenario based on a preset table, such as 72%, and initialize the screen brightness accordingly. Regardless of whether it's a historical value or the default value, the host will drive the screen backlight in real time according to the mapping curve to ensure that the interface brightness matches the displayed percentage.

[0031] Specifically, the brightness linkage adjustment module is used to monitor the user's click or slide command on the slider on the central control display screen, adjust the current interface brightness according to the user input, and update the brightness percentage display in real time; when the status of the small light or the background mode changes, the brightness recalculation logic is automatically triggered.

[0032] Furthermore, the vehicle's main unit detects that the status of the small lights changes from on to off, or from off to on, or detects that the background mode changes from dark to light, or from light to dark. In response to the detection, the host obtains a preset initial brightness percentage value corresponding to the new "light status × background mode" combination from the preset brightness table; The host takes the current display brightness percentage as the initial state and the target brightness percentage as the final state. It calculates the transition curve according to the preset brightness transition strategy and controls the backlight or panel brightness drive according to the transition curve to make the interface brightness smoothly transition to the target brightness. Once the transition is complete, the target percentage is used as the current brightness percentage and saved in the memory storage space corresponding to the current "light status × background mode" combination.

[0033] For example, when the vehicle is in normal driving mode, the user accesses the display settings interface via the central control screen. The brightness-linked adjustment module continuously monitors touch events of the slider control. When the user drags their finger along the slider, the system captures the percentage change in the slider's position in real time, for example, from "45%" to "61%". The host calculates the corresponding physical backlight level based on this percentage and immediately drives the screen backlight to update the brightness. Simultaneously, the percentage value on the right side of the slider is dynamically updated to "61%" to ensure that the interface display matches the actual brightness. If the user adjusts the brightness by clicking, for example, clicking the "70%" position on the slider, the system calculates the target percentage "70%" based on the click coordinates and directly jumps the slider to that position, simultaneously updating the brightness output. Throughout this process, the system uses the user's latest brightness percentage setting as the brightness value for the current scene and writes it to the parameter storage area corresponding to the "light status × background mode" combination, so that it can be restored after the next power-on or scene switch.

[0034] While the vehicle is in motion, the driver turns on the parking lights at dusk, and the onboard unit detects the change in the parking light status from OFF to ON. Upon receiving this status change event, the brightness adjustment module first looks up the preset initial brightness percentage value corresponding to "parking lights on × light mode" in a preset brightness table based on the current interface background mode (e.g., light mode). In this embodiment, the target brightness value is 38%. To avoid discomfort caused by sudden changes in brightness, the system executes a preset brightness transition strategy. This transition strategy includes: a transition time of 300 ms, a refresh cycle of 10 ms, and linear interpolation to calculate intermediate brightness values. The system uses the current brightness percentage "72%" as the starting point and the target percentage "38%" as the ending point, generating a transition curve sequence (e.g., 72%→68%→62%→55%→48%→42%→38%) according to the interpolation formula, and gradually outputs the corresponding backlight value throughout the transition time. The interface brightness then smoothly decreases frame by frame, and the percentage text on the slider is updated synchronously. After the transition is complete, the brightness linkage adjustment module writes the final value "38%" into the storage area of ​​"small light on × light mode" for use as the historical brightness value for this scene in the future.

[0035] When a user switches the interface theme (e.g., from light mode to dark mode), the brightness adjustment module also triggers a brightness recalculation process. The system first detects that the background mode has switched from Light to Dark, and then queries the preset brightness percentage corresponding to "light off × dark mode". In this embodiment, the preset value is 52%. The system uses the current brightness percentage (e.g., 68%) as the initial state and 52% as the target state, performing a brightness gradient according to the same transition strategy as described above. After the transition is complete, the slider synchronously displays "52%" and remembers this value as the brightness setting for the current scene.

[0036] Specifically, the brightness configuration memory module is used to write the user's brightness setting value under the combination of each small light state and background mode into the user configuration memory space of the vehicle host during the brightness adjustment process; after the vehicle is powered on again, it reads the corresponding historical brightness value according to the current small light state and background mode; if there is no historical setting, it loads the initial brightness default value of the corresponding scene.

[0037] Furthermore, during the system power-on initialization process, the vehicle host obtains the current status of the vehicle's parking lights and the interface background mode, and combines them to form a target scene identifier. The host accesses the brightness setting index table stored in the user preference memory module and queries the corresponding historical brightness percentage value based on the target scene identifier; If a valid historical brightness value is found, the historical brightness percentage is used as the initialization parameter for the current brightness, and the panel backlight is directly set to the corresponding brightness. At the same time, the brightness slider is updated to the historical percentage position. If no historical value is found or the historical value is empty, the default initial brightness corresponding to the target scene in the preset brightness table is loaded, and the panel brightness and slider display are set accordingly. After the brightness is restored, the brightness status is written into the system running status information of this startup.

[0038] Furthermore, the vehicle host accesses a preset brightness table to obtain the initial brightness default value for the scene based on the current status of the small lights and the background mode combination. The initial brightness default value is stored in percentage form. The initial brightness default value is used as the brightness start parameter for this scene to directly drive the panel backlight or display module to output the corresponding physical brightness. The brightness slider control is synchronously updated to the percentage position corresponding to the initial brightness default value, so that the UI display is consistent with the actual brightness; the default brightness value is marked as "system default value loading record" and written to the brightness status log; when the user adjusts the brightness in the current scene, the user-adjusted brightness value is overwritten and replaced with the default brightness value.

[0039] Specifically, the volume control module monitors user interactions on the central control display, identifies adjustment commands for vehicle alert volume and media volume, sets volume parameters, and outputs the adjusted status information in the output path.

[0040] Furthermore, the vehicle-mounted host monitors user interaction operations on the central control display screen, including dragging the volume slider, clicking the increase / decrease buttons, or touching a specified volume area. The host analyzes the detected touch behavior, identifies the volume type corresponding to the operation as either a notification sound volume or a media volume, and generates a corresponding volume adjustment command, which is expressed in the form of a percentage value or discrete increments. The vehicle audio management module is invoked according to the volume adjustment command to adjust the output gain parameter of the corresponding audio source channel so that the volume of the prompt tone channel or media audio channel is updated to the target volume level according to the command. After the volume parameter setting is completed, the actual set volume percentage value is sent back to the interface display module in real time, and the corresponding slider or numerical display area is updated.

[0041] Specifically, the status display module is used to obtain the current operating status, interconnection channel status, volume parameters, and brightness parameters through the vehicle's built-in information components, and to present them in real time in a visual manner.

[0042] Furthermore, the collected operating status, interconnection status, and volume and brightness parameters are formatted according to a preset data structure to generate a visual display data frame; The displayed data frame is sent to the central control display module, and is displayed in real time on the interface in the form of icons, text parameters, percentage sliders or status indicator lights.

[0043] This embodiment also provides a computer device suitable for an interconnected entertainment system, including a memory and a processor; the memory is used to store computer-executable instructions, and the processor is used to execute the computer-executable instructions to implement an interconnected entertainment system as proposed in the above embodiment.

[0044] The computer device can be a terminal, comprising a processor, memory, communication interface, display screen, and input devices connected via a system bus. The processor provides computing and control capabilities. The memory includes non-volatile storage media and internal memory. The non-volatile storage media stores the operating system and computer programs. The internal memory provides an environment for the operation of the operating system and computer programs stored in the non-volatile storage media.

7. The internet-based entertainment system as described in claim 1, characterized in that, The system monitors user interactions on the central control display screen, identifies commands to adjust vehicle alert volume and media volume, and then completes the volume parameter settings, including: The vehicle-mounted host monitors user interaction operations on the central control display screen, including dragging the volume slider, clicking the increase / decrease buttons, or touching a specified volume area. The host analyzes the detected touch behavior, identifies the volume type corresponding to the operation as either a notification sound volume or a media volume, and generates a corresponding volume adjustment command, which is expressed in the form of a percentage value or discrete increments. The vehicle audio management module is invoked according to the volume adjustment command to adjust the output gain parameter of the corresponding audio source channel so that the volume of the prompt tone channel or media audio channel is updated to the target volume level according to the command. After the volume parameter setting is completed, the actual set volume percentage value is sent back to the interface display module in real time, and the corresponding slider or numerical display area is updated.

8. The internet-based entertainment system as described in claim 1, characterized in that, The process of obtaining the current operating status, connectivity channel status, volume parameters, and brightness parameters through the vehicle's built-in information components and visually presenting them in real time includes: The collected operating status, interconnection status, and volume and brightness parameters are formatted according to a preset data structure to generate a visual data frame. The displayed data frame is sent to the central control display module, and is displayed in real time on the interface in the form of icons, text parameters, percentage sliders or status indicator lights.

9. A computer device comprising a memory and a processor, wherein the memory stores a computer program, characterized in that, When the processor executes the computer program, it implements the steps of an interconnected entertainment system as described in any one of claims 1 to 8.
