[0038] Please refer to Figure 1 , an intelligent playback method based on vehicle status, comprising the following steps:

[0039] Step 1: Receive user instructions: Obtain the user's selection of visual content, playback mode setting, or display parameter adjustment through the local interaction interface or remote communication method;

[0040] Specifically, the local interaction interfaces in the vehicle mainly include the following: AUX interface, AVI N interface, AV-I N interface, AV-OUT interface, USB interface, and Bluetooth connection interface, etc.

[0041] Among them, the AUX interface: mainly used for the input and output of additional sound signals, providing a richer entertainment experience for the driver. It supports connecting audio devices such as MP3 players, tablets, etc. Just connect the audio output of the device to the AUX interface of the vehicle using a dedicated audio cable.

[0042] AVI N interface: That is, the audio-video input interface, which is responsible for connecting the navigation screen to an external audio source to ensure synchronous display of information. It is a bridge between the navigation system and external audio devices.

[0043] AV-I N interface: Represents the input of video signals, allowing external devices to be connected for video playback, enhancing the diversity of in-vehicle entertainment.

[0044] AV-OUT interface: Represents the output of video signals, which is docked with the video output port of an external device to achieve the transmission of video signals.

[0045] USB interface: An interface with a relatively high usage frequency, which can connect storage devices such as mobile phones and USB flash drives to achieve functions such as music playback and file transfer. When using it, pay attention to the version of the interface and the insertion direction of the inserted device.

[0046] Bluetooth connection interface: Provides the possibility of wireless connection. When using Bluetooth to connect in-vehicle devices, it is necessary to first turn on the Bluetooth function in the vehicle system and pair the device with the vehicle. After successful pairing, functions such as audio playback and phone call answering can be achieved.

[0047] In addition, telecommunication usually relies on telecommunication modules, including GPRS / 3G / 4G modules, WI FI modules, etc., which can transmit the information in the vehicle to a remote server or the user's mobile phone via the Internet, so as to realize the functions of remotely controlling and monitoring the vehicle.

[0048] In this patent, select the above suitable local interface or receive the user's instructions (visual content) through telecommunication.

[0049] Step 2: Content processing and optimization: Perform data conversion, format adaptation, resolution adjustment, or color optimization on the received visual content to adapt to the characteristics of the vehicle body display screen.

[0050] Specifically, realize image enhancement, brightness equalization, resolution improvement, or color correction through AI algorithms, select appropriate tools according to requirements and devices, and these tools can be professional batch processing software or the establishment of convolutional neural networks. When selecting, consider whether the functions are comprehensive (such as supporting noise reduction, super-resolution, color correction, etc.) and whether the user interface is intuitive and easy to use.

[0051] Step 3: Display area and mode adjustment: Dynamically adjust the playback area, brightness, contrast, or display mode of the display content based on the vehicle driving state, ambient light, legal regulations requirements, or user preferences.

[0052] Specifically, adjust the display mode through GPS, acceleration sensors, and legal regulations requirements, where GPS is used for positioning and navigation, monitoring and tracking, scheduling and management, remote services, and security assurance, improve the handling, safety, and comfort through acceleration sensors, and make the display content comply with legal regulations during the vehicle driving process through specific road traffic regulations.

[0053] Step 4: Visual content output: Control the display modules on the outer surface and inner surface of the vehicle body to present visual content, supporting static display, dynamic playback, animation switching, or interactive display.

[0054] Specifically, a multi-screen collaborative display mode is used to enable the display screens at different positions on the vehicle body to play different contents synchronously or independently.

[0055] Step 5: Intelligent adjustment and safety control: Automatically adjust the display parameters according to the vehicle speed, traffic conditions, weather information, or external environment, and turn off or modify the display content when necessary to ensure safety and compliance with regulations.

[0056] Step 6: Remote management and update: Receive remote commands through wireless communication (including but not limited to Wi-Fi, cellular network or vehicle communication system) to achieve remote update of visual content, device status monitoring and display parameter adjustment.

[0057] exist Figure 1 In the method, adjusting the display content based on the vehicle driving state comprises the following steps:

[0058] S1 uses sensors to detect vehicle driving conditions including bumps, acceleration and deceleration, steering, drifting, skidding and specific values, such as acceleration, shaking degree, steering angle, etc.

[0059] S2 uses the processing module to calculate and adjust the precise parameter values ​​of the displayed content in real time according to the vehicle driving status and the specific data values ​​returned by the sensor;

[0060] S3 uses image processing algorithms to stabilize the real content according to the driving status of S2 and the calculated parameter values, ensuring that the displayed content can be output clearly and stably even during intense movements such as bumps, sudden acceleration, and sudden braking, keeping the picture still or relatively still to prevent jitter and distortion.

[0061] Specifically, image processing algorithms include image acquisition, extraction, analysis, image enhancement, target recognition and other aspects of processing.

[0062] Image acquisition and preprocessing:

[0063] Capture images through cameras or sensors.

[0064] Perform preprocessing operations such as denoising, contrast enhancement, and color correction.

[0065] Feature extraction and analysis:

[0066] Extract key features from images, such as edges, corners, textures, etc., to provide data support for subsequent classification and detection.

[0067] Target recognition and classification:

[0068] Based on the extracted features, machine learning or deep learning algorithms are used to identify and classify objects in the image.

[0069] Post-processing and feedback:

[0070] Provide decision feedback based on the recognition results, such as object location, defect detection, action recognition, etc.

[0071] Image Segmentation:

[0072] Image segmentation is to extract the meaningful feature parts in an image. The meaningful features include edges, regions, etc. in the image, which is the basis for further image recognition, analysis, and understanding.

[0073] Commonly used image segmentation algorithms include threshold segmentation, region growing, and graph cut algorithms, etc.

[0074] Image transformation and enhancement:

[0075] Image transformation includes spatial domain and frequency domain, geometric transformation, chromaticity transformation, scale transformation, etc.

[0076] Image enhancement does not consider the reasons for image degradation, but highlights the parts of interest in the image. For example, strengthening the high-frequency components of the image can make the object contours in the image clear and the details obvious.

[0077] Image features:

[0078] Include geometric features, shape features, histogram features, etc.

[0079] Image / template matching:

[0080] Such as contour matching, normalized product correlation gray-level matching, etc.

[0081] Thus, it ensures the stabilization of the real content, and ensures that the displayed content can also be clearly and stably output during violent movements such as bumping, sudden acceleration, and sudden braking, keeping the picture still or relatively still compared to before, and preventing jitter and distortion.

[0082] In Figure 1 it, the steps of content processing and optimization include image enhancement, brightness equalization, resolution improvement, or color correction based on artificial intelligence (AI) algorithms to adapt to different types of vehicle body displays.

[0083] Specifically, image enhancement, brightness equalization, resolution improvement, or color correction are achieved by constructing a convolutional neural network:

[0084] Among them, for image enhancement: The CNN can extract multi-scale features of the image by constructing a deep network structure, and achieve complex image enhancement tasks such as super-resolution and style transfer;

[0085] For brightness equalization: Through model training, the CNN can automatically adjust the brightness distribution of the image to achieve brightness equalization;

[0086] For resolution improvement: The CNN performs excellently in super-resolution reconstruction and can convert low-resolution images into high-resolution images;

[0087] For color correction: The CNN can identify and adjust the color of the image to achieve color correction.

[0088] InFigure 1 Among them, the steps of display area and mode adjustment are based on GPS location information, acceleration sensor data or road traffic regulations to automatically adjust or turn off specific visual content in certain areas and adjust the playback mode based on vehicle status data, including but not limited to:

[0089] Low-speed mode: Allows playing full video content;

[0090] High-speed mode: Reduces the playback of dynamic images and only displays static or simplified information;

[0091] Night mode: Reduces the screen brightness to reduce interference to other drivers.

[0092] Specifically, the main functions of the vehicle GPS include positioning and navigation, monitoring and tracking, dispatching and management, remote services, and safety guarantee.

[0093] Positioning and navigation: GPS can accurately locate the vehicle's position, thus facilitating the control of in-vehicle devices from outside the vehicle.

[0094] Monitoring and tracking: Through GPS, the vehicle owner or relevant management agencies can monitor information such as the vehicle's position, speed, and driving direction in real time, and record the vehicle's driving trajectory, facilitating the adjustment of video playback content and playback mode according to road conditions, driving direction, and driving speed, reducing interference to the driver, and at the same time providing richer entertainment content.

[0095] Remote services: Combined with other technologies, GPS can provide remote vehicle diagnosis, emergency rescue services, and remote control of certain vehicle functions (such as turning off the engine and starting), thus further ensuring vehicle safety.

[0096] Safety guarantee: In case of an emergency, GPS positioning can help find the vehicle's position in time, provide rescue services, increase driving safety. At the same time, GPS also helps prevent the occurrence of phenomena such as vehicle theft and robbery.

[0097] In Figure 1 Among them, intelligent adjustment and safety control also include controlling the display of white or other light-colored systems on the outer surface of the vehicle body in a hot sun environment to prevent the display screen from overheating too quickly and protect the display screen.

[0098] In Figure 1 Among them, the steps of visual content output include a multi-screen collaborative display mode to enable the display screens at different positions on the vehicle body to play different contents synchronously or independently.

[0099] Specifically, it includes the following steps:

[0100] S1 Start the collaborative function: On a device that supports multi-screen collaboration, open the corresponding collaborative software and complete the connection between devices according to the interface prompts;

[0101] S2 Screen sharing and operation: After successful connection, real-time sharing of screen content can be achieved, and the screen content of in-vehicle devices can be directly controlled by out-of-vehicle devices;

[0102] S3 Optimize the visual experience: According to actual needs, adjust parameters such as the resolution, scaling ratio, and display orientation of each display to ensure the best visual experience.

[0103] In addition, it also includes that the intelligent adjustment and safety control steps automatically optimize the display brightness, contrast, or playback content based on the ambient light sensor, camera analysis, or V2X vehicle networking communication to ensure visibility and safety at night or in complex traffic environments.

[0104] Specifically, the remote management and update steps support the vehicle owner to remotely upload or edit visual content through the cloud server or local storage, and allow the vehicle to automatically synchronize and update, so that the visual playback content better meets the needs of users.

[0105] In summary, the intelligent playback method based on vehicle status realizes the remote control of the broadcast content through the above steps, and can be adjusted and optimized according to the needs of users to make the output content better meet the needs of users. Through remote management and update, the visual content can be updated in real time, making it more intelligent and providing a better vehicle use experience for vehicle owners.

[0106] Moreover, when controlling in-vehicle devices, first obtain the user's selection of visual content, playback mode setting, or display parameter adjustment through the local interaction interface or remote communication method, then perform data conversion, format adaptation, resolution adjustment, or color optimization on the received visual content to adapt to the characteristics of the vehicle body display screen. Based on the vehicle driving status, ambient light, legal requirements, or user preferences, dynamically adjust the playback area, brightness, contrast, or display mode of the display content, and then control the display modules on the outer surface and inner surface of the vehicle body to present the visual content, supporting static display, dynamic playback, animation switching, or interactive display. At this time, automatically adjust the display parameters according to the vehicle speed, traffic conditions, weather information, or external environment, and close or modify the display content when necessary to ensure safety and regulatory compliance. Finally, receive remote instructions through wireless communication methods (including but not limited to Wi-Fi, cellular network, or in-vehicle communication system) to achieve remote update of visual content, device status monitoring, and display parameter adjustment.
