Detailed Embodiments

[0027] Hereinafter, the embodiments of the present invention will be described with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. It should be understood that the preferred embodiments are only for illustrating the present invention, rather than for limiting the protection scope of the present invention.

[0028] It should be noted that the diagrams provided in the following embodiments only schematically illustrate the basic concept of the present invention. The diagrams only show the components related to the present invention, rather than being drawn according to the number, shape and size of the components in actual implementation. The type, quantity and proportion of each component in actual implementation can be arbitrarily changed, and the component layout type may also be more complex.

[0029] Such as Figure 1A vehicle 1 as shown has external display areas respectively provided on multiple outer surfaces of the vehicle 1, and the external display areas are used to display images to the outside of the vehicle 1. With the above technical solution, by providing external display areas on multiple outer surfaces of the vehicle 1, a multi-directional external display area can be formed outside the vehicle 1. Using more external display areas can better and more display images to the outside of the vehicle. Moreover, multiple external display areas can display images in multiple directions, which can better achieve communication between vehicles 1, reduce misjudgment during driving, and effectively ensure driving safety. By providing external display areas on multiple outer surfaces of the vehicle 1, information can be transmitted to the outside of the vehicle more fully, clearly, and efficiently.

[0030] In specific implementation, as Figure 1 shown, the multiple external display areas include a left display area 11 located on the left side of the vehicle 1, a right display area 12 located on the right side of the vehicle 1, a front display area 13 located on the front side of the vehicle 1, a rear display area 14 located on the rear side of the vehicle 1, and a top display area 15 located on the top of the vehicle 1.

[0031] In some embodiments, the external display areas are formed by multiple vehicle appearance parts of the vehicle 1. Using multiple vehicle appearance parts to form the external display areas can form a larger-area external display area, which can transmit information to the outside of the vehicle more fully, clearly, and efficiently. Moreover, the larger-area external display area can be used as a movie screen for playing movies and a KTV screen for playing MVs, expanding the usage scenarios of the external display areas. And, the larger-area external display area can display images better and more clearly, can better achieve communication between vehicles 1, reduce misjudgment during driving, and effectively ensure driving safety.

[0032] As a specific example, as Figure 2 shown, the outer door panel and window glass of the right front door of the vehicle 1 are both glass parts with display functions, and the outer door panel and window glass of the right front door respectively form a first sub-display area 121 and a second sub-display area 122. The outer door panel and window glass of the right rear door of the vehicle 1 are both glass parts with display functions, and the outer door panel and window glass of the right rear door respectively form a third sub-display area 123 and a fourth sub-display area 124. The first sub-display area 121, the second sub-display area 122, the third sub-display area 123, and the fourth sub-display area 124 are combined into a continuous and larger-area right display area 12. The right display area 12 can be used as a movie screen, can display more and larger images, can transmit information to the outside of the vehicle more clearly and efficiently, and also expands the usage scenarios of the external display areas.

[0033] As a specific example, as Figure 3 shown, both the rear windshield and the outer panel of the rear door of the vehicle 1 are glass parts with a display function. The rear windshield and the outer panel of the rear door of the vehicle form a fifth sub-display area 141 and a sixth sub-display area 142 respectively. The fifth sub-display area 141 and the sixth sub-display area 142 are combined to form a continuous and relatively large rear-side display area 14.

[0034] In some embodiments, multiple vehicle exterior parts that constitute an external display area are all glass parts with a display function. Setting multiple vehicle exterior parts as glass parts has the characteristics of being easy to implement and easy to clean.

[0035] In some embodiments, the glass part includes a display panel layer for displaying images. The display panel layer is the key structure for the glass part to achieve the display function. By setting the display panel layer, more types and more complex images can be displayed more clearly. In specific implementation, the display panel layer can select a flexible light-transmitting display panel, such as a flexible OLED panel. The display panel layer can be clamped between two glass layers to form a glass part with the function of displaying images.

[0036] In some embodiments, the glass part includes a dimming layer for adjusting the light transmittance of the glass part. Setting the dimming layer can adjust the light transmittance of the glass part to prevent the sun from being dazzling. In specific implementation, a light sensor can be set inside the vehicle 1, and the vehicle-mounted controller of the vehicle 1 collects the signal of the light sensor. Based on the collected signal, the dimming layer is automatically controlled according to a preset rule to adjust the light transmittance of the glass part. By setting the dimming layer and the light sensor, the light transmittance of the glass part can be automatically adjusted, and it will not cause the sun to be dazzling due to too many glass parts. At the same time, the light transmittance of the glass part can also be manually set on the in-vehicle system to ensure the personalized use of customers.

[0037] In specific implementation, the dimming layer can be implemented by an electrochromic film. The dimming layer can be a part of the display panel layer, and the display panel layer is used to achieve the dimming function.

[0038] In some embodiments, the glass part includes a solar power generation layer. The glass parts of the whole vehicle can be used as an energy system to convert solar energy into electrical energy. The solar power generation layer is connected to the vehicle-mounted energy system to supplement energy for the vehicle 1.

[0039] In some embodiments, a self-cleaning coating is provided on the outer surface of the glass part, and the self-cleaning coating can ensure the cleanliness of the vehicle 1. In specific implementation, the self-cleaning coating can adopt a super-hydrophobic coating. Through the super-hydrophobic principle, water droplets form aggregated water beads on the surface of the glass part. When these water beads slide down under the action of gravity, they can slide down together with stains, thereby cleaning the glass part.

[0040] Moreover, the self-cleaning coating can have a photocatalytic effect, using chemical reactions generated by photocatalysts such as titanium dioxide (TiO2) under ultraviolet irradiation to decompose organic substances (such as dust, stains, etc.) on the surface of the glass parts, and convert the organic substances on the surface of the glass parts into harmless water and carbon dioxide.

[0041] In some embodiments, all the vehicle exterior parts located on the left side of the vehicle 1 are glass parts, all the vehicle exterior parts located on the right side of the vehicle 1 are glass parts, all the vehicle exterior parts located on the top of the vehicle 1 are glass parts, all the vehicle exterior parts located on the front side of the vehicle 1 are glass parts, and all the vehicle exterior parts located on the rear side of the vehicle 1 are glass parts. That is to say, all the vehicle exterior parts of the vehicle 1 are glass parts, which can form multiple large-area external display areas with different orientations, can transmit information to the outside of the vehicle more fully, clearly and efficiently, expand the usage scenarios of the external display areas of the vehicle 1, and help improve the user's driving experience and effectively ensure driving safety.

[0042] When the above-mentioned vehicle 1 is in use, since all the vehicle exterior parts of the vehicle 1 are glass parts, the whole vehicle can be presented in a transparent state and can be used as a camping tent, and users can look up at the stars in the car. Moreover, multiple external display areas of the vehicle 1 can be used to display mobile advertisements, and the display content can be customized to create a promotional effect.

[0043] In some embodiments, the vehicle 1 includes a control module, and the control module is used for: obtaining the information input by the user, determining the target display area and the target display image based on the information, and controlling the external display area corresponding to the target display area to display the target display image. The control module can be implemented by using in-vehicle control components, such as an in-vehicle controller.

[0044] In some embodiments, the vehicle 1 includes a car machine system, and the car machine system is connected to the external display area so that the external display area can be used to display the image provided by the car machine system.

[0045] Information can be transmitted between the car machine system and the external display area through Ethernet, and the information in the car machine system can be automatically rendered onto the external display area.

[0046] In specific implementation, the content displayed in the external display area can also be controlled by voice. With the help of the AI model in the vehicle 1, the voice of the people in the car is recognized, the voice is converted into text, the text content to be displayed is automatically intercepted, and then it is displayed in the corresponding external display area.

[0047] For example, when the user issues a voice command: "Show Newbie on the rear screen", the AI model will recognize "Show on the rear screen" and recognize that the user's intention is to display content on the vehicle body. Then the vehicle body content display program can be called to intercept the content to be displayed "Newbie" and display it in the external display area on the rear side of the vehicle specified in the command.

[0048] It should be noted that voice commands do not have a fixed grammar. With the help of the vehicle's AI model, content such as "Tell the car on the left xxx", "Show xxx on the right", "Friends behind xxx", "Show xxx at the rear of the vehicle" spoken by the user can all be recognized and corresponding display operations can be performed.

[0049] In addition, it is also possible to train shortcut commands to control the content displayed in the external display area. For example, when the user directly wakes up the voice assistant and says "I'm about to make a U-turn", the external display area at the rear of the vehicle automatically displays "I'm about to make a U-turn!" and a U-turn sign. Another example is that when the user directly wakes up the voice assistant and says "Danger ahead", the LED at the rear of the vehicle automatically starts flashing, and a danger warning graphic is rendered in the external display area at the rear of the vehicle to remind the following vehicle to slow down.

[0050] The above-mentioned vehicle 1 also has the following usage scenarios: outdoor KTV scenario, using the external display area as an MV playback screen, and realizing voice playback and voice signal transmission through the in-vehicle audio system and wireless receiving module, so that users can enjoy KTV entertainment outdoors. Movie playback scenario, the external display area is connected to the in-vehicle system, and by entering the in-vehicle system settings interface, the external display area is selected as the display screen to play movies.

[0051] In specific use, the user can also use the in-vehicle system to call the setting program, input the content to be displayed, and then the content can be displayed in the corresponding external display area.

[0052] As Figure 4 shown, the present invention also proposes a display method. The display method is used to control the vehicle 1. External display areas are respectively arranged on the outer surfaces of multiple sides of the vehicle 1, and the external display areas are used to display images to the outside of the vehicle 1; the display method includes the following steps: S100: Obtain the information input by the user; S200: Determine the target display area and the target display image based on the information; S300: Control the external display area corresponding to the target display area to display the target display image.

[0053] In some embodiments, determining the target display area and the target display image based on the information includes the following steps: identifying whether the information contains the intention of displaying an image to the outside of the vehicle 1 through the external display area; when it is recognized that the information contains this intention, analyze the information to determine the target display area and the target display image.

[0054] In some embodiments, determining the target display area and the target display image based on information includes the following steps: When the information is voice information, call a semantic recognition model to recognize the information, and determine the target display area and the target display image according to the recognition result. The semantic recognition model can adopt the AI model of vehicle 1, and the AI model can be a pre-trained model.

[0055] As a specific example, the user can issue an instruction to display text through an idiom, such as: "Show thank you later" or "Say thank you to the car behind". At this time, the external display area on the rear side of vehicle 1 can display "Thank you".

[0056] As a specific example, when the AI model of vehicle 1 performs semantic recognition on the voice information input by the user and determines that the user has the intention to display information to other vehicles 1 through the external display area, the display content analysis program can be started to analyze two elements included in the user instruction: the target display area and the target display image. The analysis result of the previous specific example is: the target display area is the external display area on the rear side, and the target display image is the text "Thank you".

[0057] The training model for recognizing voice information can adopt the hidden Markov model as the basic model, or other models, which are not specifically limited in the present invention. A specific recognition process is as follows: Collect the voice audio information input by the user, and convert the voice audio information into an audio spectrogram. Obtain the feature information of the audio frame, and generate a feature data set from the feature information, and determine the number of convolutional network layers and the number of fully connected network layers of the convolutional neural network model. Calculate the output data of any convolutional network layer and any fully connected network layer in the convolutional neural network model respectively, and use a splicing function to splice the output data of the convolutional network layer and the output data of the fully connected network layer to obtain a deep representation. Perform fusion on the deep representation to obtain fusion data, and calculate the output result of the convolutional neural network model according to the fusion data and the activation function, where the Softmax function is used as the activation function of the last layer of the neural network. Use the cross-entropy function as the loss function, and update the model parameters by minimizing the loss function through stochastic gradient descent based on the output result of the convolutional neural network model to obtain a feature fusion model. Input the feature data set into the feature fusion model, and perform feature association according to the output result of the feature fusion model to obtain the data to be recognized. Input the transcription text sequence output by the semantic sub-model into the grammar sub-model to supplement the transcription text sequence to obtain the recognized text. The target display area and the target display image can be obtained from the recognized text.

[0058] It should be noted that the images displayed in the external display area in this application include various visual information, which can be graphics and text, or videos and photos, and can be static visual information or dynamic visual information.

[0059] The present invention also provides a storage medium, on which a computer program is stored. When the computer program is executed by a processor, the display method described in any one of the above is implemented.
