These drawings and text descriptions are not intended to limit the scope of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0048] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0049] With the continuous advancement of vehicle technology, the cockpit system of existing driverless vehicles can already provide a variety of basic functions, such as safety monitoring, which can monitor the traffic conditions outside the vehicle, identify pedestrians, vehicles and obstacles, and take automatic braking or avoidance measures when necessary, navigation information can provide accurate navigation information, and information display can let passengers know the status of the vehicle in real time. In addition, the cockpit system also integrates an advanced human-computer interaction interface, allowing passengers to interact with the system through touch screens, voice commands, etc., which improves the convenience of operation and the pleasure of riding.

[0050] However, in driverless vehicles, passengers often feel uncomfortable because they are in a small cabin. This discomfort is caused by the combined influence of multiple factors. First, the continuous noise during driving will disturb the passengers. In addition, the closed and isolated environment in the cabin limits the passengers' activity space, which can easily cause loneliness and boredom. These factors work together, usually increasing the negative emotions of passengers, such as anxiety, irritability and fatigue, thereby reducing the passengers' riding experience.

[0051] In response to the above problems, the inventors considered that the emotional state of the passengers could be identified, and when it is determined that the emotional state of the passengers is negative, the environment in the cabin can be adjusted to improve the emotional state of the passengers and enhance the passenger's riding experience. Specifically, when it is determined that the emotional state of the passengers is negative, suitable virtual environment images and background audio can be generated and displayed to the passengers through virtual reality, creating a relaxing and pleasant virtual space for the passengers. In addition, the physical environment in the cabin can also be adjusted, such as adjusting the brightness and color temperature of the lighting to create a more comfortable visual environment. Through the coordination of multiple senses, the passenger's riding experience is comprehensively improved. Based on this, the present application proposes an environmental control method based on emotional state to further improve the riding experience of passengers in the cabin.

[0052] Figure 1 This is a schematic diagram of an application scenario provided by an embodiment of the present application. Figure 1 The unmanned vehicle 10 includes a cockpit domain controller 11 and a cockpit 12 that can carry passengers. During the driving process of the unmanned vehicle 10, the cockpit domain controller 11 can adjust the environment in the cockpit 12 to improve the emotional state of the passengers, thereby improving the riding experience of the passengers.

[0053] It should be noted that the application scenarios applicable to this application are not limited to unmanned vehicles, but can also be extended to manned aircraft, unmanned flying cars and other fields.

[0054] The technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems are described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0055] Figure 2 This is a flow chart of the first embodiment of the emotional state-based environment control method provided in this application. Figure 2 , the method comprising:

[0056] S201: If it is identified that the emotional state of the passenger in the cabin is a negative state, a virtual environment image is determined according to the emotional state of the passenger and the environmental parameters in the cabin.

[0057] The execution subject of the embodiment of the present application may be a cockpit domain controller, or an emotional state-based environment control device set in the cockpit domain controller. The emotional state-based environment control device may be implemented by software, or by a combination of software and hardware. The emotional state-based environment control device may be a processor in the cockpit domain controller. For ease of understanding, the following description is made by taking the cockpit domain controller as an example.

[0058] In this step, the cockpit domain controller can obtain the environmental parameters in the cockpit through sensors installed in the cockpit. When it is identified that the emotional state of the passengers in the cockpit is negative, the virtual environment image can be determined based on the emotional state of the passengers and the environmental parameters in the cockpit.

[0059] Optionally, negative emotional states may include sadness, grief, sadness, anger, fear, anxiety, disappointment, loneliness, etc. Positive emotional states corresponding to negative emotional states may include happiness, excitement, satisfaction, gratitude, confidence, etc.

[0060] Environmental parameters may include cabin temperature, cabin humidity, and cabin light intensity. Optionally, the cabin temperature, cabin humidity, and cabin light intensity may be acquired by a temperature sensor, a humidity sensor, and a light sensor disposed in the cabin.

[0061] For virtual environment images, they can be visual content used to improve negative emotional states, and can include natural scenery, tranquil beaches, starry night scenes, gorgeous flowers, or other scenes with soothing effects.

[0062] For example, when the driverless vehicle is driving, the cockpit domain controller can collect the cabin temperature of 10 degrees Celsius (℃) through the temperature sensor set in the cabin, collect the cabin humidity of 5%, and collect the cabin light intensity of 100 lux through the light sensor. When the emotional state of the passenger in the cabin is identified as anxious, the virtual environment image can be determined as a quiet beach based on the emotional state of anxiety and the environmental parameters in the cabin.

[0063] S202: Determine background audio and target environment parameters that match the virtual environment image according to the virtual environment image.

[0064] In this step, after determining the virtual environment image, the cockpit domain controller can generate audio matching the virtual environment image to obtain background audio; and determine target environment parameters for adjusting the environment parameters in the cockpit according to the virtual environment image.

[0065] In an optional implementation, a pre-acquired background audio generation model may be used to process the virtual environment image to generate audio matching the virtual environment image to obtain background audio. The background audio generation model is obtained by training a deep learning model based on multiple virtual environment images and the background audio corresponding to each virtual environment image. The deep learning model may be a convolutional neural network (CNN).

[0066] In another optional implementation, a mapping relationship between the virtual environment image and the background audio is pre-established in the database of the cockpit domain controller, and the background audio matching the virtual environment image can be determined from the database based on the pre-established mapping relationship.

[0067] Background audio may be auditory content used to improve negative emotional states, and may include birdsong, breeze, waves, flowing water, or other sounds with a soothing effect.

[0068] For example, according to the pre-established mapping, it can be determined that the background audio that matches the natural scenery is the sound of birdsong; the background audio that matches the quiet beach is the sound of breeze; and the background audio that matches the starry night view is the sound of flowing water.

[0069] Optionally, the target environment parameter may include at least one of a target temperature, a target humidity, and a target light intensity in the cabin. For example, according to the virtual environment image of a quiet beach, the target environment parameters may be determined to include: a target temperature of 18° C., a target humidity of 15%, and a target light intensity of 150 Lux.

[0070] S203: Display the virtual environment image and background audio to the passengers in a virtual reality manner, and control the environment in the cabin according to the target environment parameters.

[0071] In this step, virtual reality technology can be used to display virtual environment images and background audio to passengers in an immersive manner, and the environment in the cabin can be adjusted according to target environmental parameters to enhance the riding experience.

[0072] In an optional implementation, the virtual environment image and background audio may be fused to generate a virtual reality video, which is then input into a brain-computer interface (BCI) worn by the passenger to enhance the passenger's sense of reality.

[0073] Optionally, the temperature in the cabin can be adjusted by a temperature control system according to the target temperature in the target environmental parameters; the humidity in the cabin can be adjusted by a humidity control system according to the target humidity in the target environmental parameters; and the light intensity in the cabin can be adjusted by a light adjustment system according to the target light intensity in the target environmental parameters.

[0074] For example, the tranquil beach and the sound of the breeze can be fused through virtual reality technology to generate a highly immersive virtual reality video, which can be input into the brain-computer interface worn by passengers to enhance the passengers' sense of reality. In addition, the cabin temperature of 10°C, the cabin humidity of 5%, and the cabin light intensity of 100Lux can be adjusted according to the target environmental parameters, including the target temperature of 18°C, the target humidity of 15%, and the target light intensity of 150Lux, to ensure that the environment is consistent with the virtual reality video.

[0075] In the embodiment of the present application, if the cockpit domain controller identifies that the emotional state of the passenger in the cockpit is negative, the virtual environment image can be determined according to the emotional state of the passenger and the environmental parameters in the cockpit; the background audio and target environmental parameters matching the virtual environment image can be determined according to the virtual environment image, and then the virtual environment image and background audio can be presented to the passenger through virtual reality technology. At the same time, the environment in the cockpit is adjusted according to the target environmental parameters to improve the emotional state of the passenger and enhance the riding experience.

[0076] exist Figure 2 Based on the embodiment shown below, combined with Figure 3 , the above-mentioned emotional state-based environment control method is further described in detail.

[0077] Figure 3 This is a flow chart of the second embodiment of the emotional state-based environment control method provided in this application. Figure 3, the method may include:

[0078] S301. Collect passengers' brain wave information in real time through brain-computer interface.

[0079] In this step, the cockpit domain controller can communicate with the BCI to obtain the passengers' brain wave information collected by the BCI in real time.

[0080] In a specific implementation, when an unmanned vehicle is traveling for a long time, passengers can wear BCI to interact with the vehicle, and the cockpit domain controller can communicate with the BCI to obtain the passenger's brain wave information collected in real time by the BCI.

[0081] Optionally, brain wave information generally refers to brain activity data recorded and analyzed by electroencephalogram (EEG) technology, where EEG is an electrical signal generated by brain neuron activity, which can be detected by an EEG sensor. The EEG signal sampling frequency can be preset. For example, the EEG signal sampling frequency can be 200 Hz.

[0082] Specifically, the brain's electrical activity signals can be collected through the electroencephalogram sensor array in the BCI, and the electrical activity signals can be pre-amplified to enhance the strength of the electrical activity signals. Subsequently, a filter can be used to remove noise and other unnecessary frequency components, thereby improving the quality and accuracy of the signal. Finally, the filtered electrical activity signals can be digitized to extract differential entropy features and obtain brain wave information.

[0083] S302: Use the pre-acquired emotion recognition model to perform emotion recognition on the brain wave information to determine the emotional state of the passenger.

[0084] In this step, the emotion recognition model acquired in advance can be used to perform emotion recognition processing on the brain wave information. By analyzing the collected brain wave information, the model can identify the emotional state of the passenger and determine whether the current emotion is in a positive state or a negative state. The emotion recognition model is obtained by training a deep learning model based on brain wave information and preset emotional state labels.

[0085] Optionally, the emotion recognition model can be obtained through the following steps.

[0086] Step ①: Construct multiple training samples, each of which includes a brain wave information and a preset emotional state label. The emotional state label can be multi-classified, such as happy, sad, angry, anxious, etc.

[0087] Step ②: Based on multiple training samples, train the deep learning model to obtain an emotion recognition model. The deep learning model may be a convolutional neural network.

[0088] For example, a pre-acquired emotion recognition model may be used to perform emotion recognition on brain wave information to determine that the passenger's emotional state is an anxious state.

[0089] In an optional implementation, the emotional state of the passenger may also be determined by any one of the following methods.

[0090] Method 1: Collecting the passenger's facial expression and determining the passenger's emotional state based on the facial expression. Specifically, the passenger's facial expression can be collected by an image acquisition device such as a camera installed inside the vehicle.

[0091] Method 2: Collecting the passenger's voice or tone, and determining the passenger's emotional state based on the voice or tone. Specifically, the passenger's voice or tone can be collected by a voice collection device such as an audio sensor installed inside the vehicle.

[0092] It should be noted that a comprehensive analysis may be performed on at least two of the acquired brain wave information, facial expressions, and voice or intonation information to improve the accuracy of emotional state recognition.

[0093] S303: If it is identified that the emotional state of the passenger in the cabin is a negative state, determine an adjusted target emotional state according to the emotional state.

[0094] In this step, a target emotional state can be determined based on identifying that the emotional state of the passenger in the cabin is a negative state, wherein the target emotional state can be a positive emotional state opposite to the negative emotional state.

[0095] For example, if the emotional state of the passenger in the cabin is identified as anxious, the target emotional state may be relaxed; if the emotional state of the passenger in the cabin is identified as sad, the target emotional state may be happy.

[0096] In an optional implementation, an emotion mapping relationship between a negative state and a target emotion state is pre-established in a database of the cockpit domain controller, and a positive emotion state opposite to the negative emotion state can be determined from the database based on the pre-established emotion mapping relationship.

[0097] S304: Using the pre-acquired environment image generation model, process the environment parameters and the target emotional state to determine the virtual environment image.

[0098] In this step, the pre-acquired environment image generation model can be used to process the environment parameters acquired by the sensors in the cabin and the determined target emotional state to generate a virtual environment image that can enable the passenger to reach the target emotional state. The environment image generation model is obtained by training a deep learning model based on multiple sets of environment parameters and the emotional state corresponding to each set of environment parameters.

[0099] Optionally, the environment image generation model can be obtained through the following steps.

[0100] Step ①: Construct multiple training samples. Each training sample includes a set of environmental parameters, the emotional state corresponding to the set of environmental parameters, and the corresponding virtual environment image.

[0101] Step ②: Based on multiple training samples, the deep learning model is trained to obtain an environmental image generation model. The deep learning model may be a Generative Adversarial Network (GAN).

[0102] For example, a pre-acquired environmental image generation model can be used to process the environmental parameters acquired by the cabin sensor and the determined target emotional state as a relaxed state to generate a virtual environmental image that can make passengers reach a relaxed state. The virtual environmental image can be a quiet beach; the environmental parameters acquired by the cabin sensor can include: the cabin temperature is 10°C, the cabin humidity is 5%, and the cabin light intensity is 100Lux.

[0103] S305: Generate audio that matches the virtual environment image to obtain background audio.

[0104] For example, a mapping relationship between a virtual environment image and background audio is pre-established in the database of the cockpit domain controller, and according to the pre-established mapping relationship, it can be determined from the database that the background audio matching the quiet beach is the sound of breeze.

[0105] S306: Using the pre-acquired environment parameter determination model, the virtual environment image and the target emotional state are processed to determine the target environment parameters.

[0106] In this step, the pre-acquired environment parameter determination model can be used to process the generated virtual environment image and the determined target emotional state to determine the target environment parameters for adjusting the environment parameters in the cabin. The environment parameter determination model is obtained by training a deep learning model based on multiple virtual environment images and the emotional state corresponding to each virtual environment image.

[0107] Optionally, the environmental parameters can be obtained by the following steps to determine the model.

[0108] Step ①: Construct multiple training samples. Each training sample includes a virtual environment image, the emotional state corresponding to the virtual environment image, and the corresponding environment parameters.

[0109] Step ②: Based on multiple training samples, train the deep learning model to obtain an environment image generation model. The deep learning model may be a convolutional neural network.

[0110] For example, the model for determining the environmental parameters acquired in advance can be used to process the generated virtual environment image as a quiet beach and the determined target emotional state as a relaxed state, and determine the target environmental parameters for adjusting the environmental parameters in the cabin. The target environmental parameters may include: the target temperature in the cabin is 18°C, the target humidity is 15%, and the target light intensity is 150 Lux.

[0111] S307: Fusing the virtual environment image and the background audio to generate a virtual reality video.

[0112] In this step, the virtual environment image and the background audio can be fused to generate an immersive virtual reality video. In a specific implementation, the virtual environment image and the background audio can be synchronously fused to ensure the coordination of vision and hearing. Spatial audio technology is used to enhance the directionality and depth of sound, so that passengers can perceive the source and distance of the sound, thereby enhancing the overall immersion. Then, the processed audio can be combined with the virtual environment image through rendering technology to generate a highly immersive virtual reality video.

[0113] S308. Input the virtual reality video into the brain-computer interface worn by the passenger, and control the environment in the cabin according to the target environment parameters.

[0114] In this step, the generated virtual reality video can be input into the brain-computer interface worn by the passenger to achieve a deeper interactive experience. At the same time, the environmental parameters in the cabin can be adjusted to match the target environmental parameters to enhance the authenticity of the virtual reality experience.

[0115] In an optional implementation, the virtual reality video can be encoded and processed to obtain neural signals so as to match the natural signal pattern of the human brain. Then, the neural signals are input into the brain-computer interface worn by the passenger. In a specific implementation, the virtual reality video can be encoded into neural signals through a memristor array, and the processed neural signals are input into the brain through the brain-computer interface worn by the passenger to achieve a true perception of the virtual reality video.

[0116] In another optional implementation, the virtual reality video can also be displayed to passengers in a more immersive and interactive way through high-resolution display devices, such as holographic images and mixed reality (MR) devices. These devices can provide realistic visual effects and dynamic environmental interactions, allowing passengers to not only watch virtual reality videos, but also interact with the video content in real time, enhancing the passenger experience.

[0117] In a specific implementation, when adjusting the light intensity in the cabin according to the target light intensity included in the target environment parameter, the cockpit domain controller can achieve this by setting a programmable LED light in the light adjustment system. Specifically, the cockpit domain controller can adjust the color and brightness of the LED light in the light adjustment system according to the target light intensity, thereby adjusting the light intensity in the cabin.

[0118] For example, there are 256 programmable LED lights in the cockpit. The cockpit domain controller can calculate the difference between the current light intensity of 100 Lux and the target light intensity of 150 Lux based on the target light intensity of 150 Lux, and adjust the brightness output of each LED lamp in the lighting control system according to the difference to achieve the target light intensity of 150 Lux.

[0119] In an embodiment of the present application, the cockpit domain controller can collect the passenger's brain wave information through the brain-computer interface and use the emotion recognition model to identify the emotional state. According to the emotional state being a negative state, the target emotional state is determined, and a virtual environment image and matching background audio are generated. Then, the environmental parameter determination model is adopted to process the virtual environment image and the target emotional state, determine the target environmental parameters, fuse the virtual environment image and the background audio, generate a virtual reality video, input the virtual reality video into the brain-computer interface worn by the passenger, and adjust the cabin environment according to the target environmental parameters. In the above process, by identifying the negative emotional state of the passenger, a virtual reality video for improving the emotion can be generated, and the target environmental parameters of the cabin environment can be adjusted, thereby improving the passenger's riding experience.

[0120] Furthermore, the emotional state-based environment control method provided in this embodiment, combined with the brain-computer interface, can convert virtual reality videos into neural signals, directly acting on the passenger's brain, creating an immersive feeling for the passenger and enhancing the sense of immersion; combined with the adjustment of the cabin environment parameters, it can improve the passenger's riding comfort, further help passengers improve their negative emotional states, and comprehensively improve the riding experience.
