Description

Technical Field

[0001] This invention relates to the field of automation control technology, and more specifically, to a control method, device, vehicle, and storage medium for a vehicle audio system. Background Technology

[0002] Against the backdrop of continuous evolution in automotive intelligence, in-vehicle audio systems and automatic air conditioning systems have developed independently. While they have achieved a high level of automation, they have failed to form effective technological synergy. Especially in high-end models, automatic air conditioning systems, with their sophisticated sensor networks and complex control algorithms, can precisely adjust the in-vehicle environment to adapt to different climate conditions and passenger needs. Meanwhile, advanced audio systems strive to create a superior listening experience for users through diverse sound field settings and automatic volume adjustment.

[0003] However, both technologies exhibit significant limitations in practical applications. On one hand, audio systems often overlook the wind noise generated by the air conditioning system, especially when the air conditioning is operating at high load. The significant wind noise can severely mask music, navigation voices, or phone calls, forcing users to frequently adjust the volume manually. This distracts the driver and reduces the continuity and safety of the user experience. On the other hand, while audio systems can adjust volume based on vehicle speed and external environmental factors, they fail to match the micro-environment created by the air conditioning system, resulting in a disconnect in the overall experience. For example, when the air conditioning is at full cooling or heating, the content played on the audio system does not change accordingly, failing to create a truly integrated and comfortable driving environment.

[0004] Therefore, the lack of effective intelligent linkage between in-vehicle audio and air conditioning systems has led to poor auditory experience, fragmented contextual experience, and low energy efficiency, which has become an urgent problem to be solved. Summary of the Invention

[0034] Figure 1 This is a flowchart of a vehicle audio control method according to one embodiment of the present invention, such as... Figure 1 As shown, the method includes the following steps:

[0035] Step S102: Obtain the current airflow of the vehicle air conditioner and the current temperature value inside the target vehicle.

[0036] Optionally, the execution subject in this embodiment is the vehicle audio control system. It should be noted that other electronic devices and processors can also be used as the execution subject, and no further limitations are made here.

[0037] In the technical solution provided in step S102 of the present invention, the vehicle audio system directly reads the status information sent by the vehicle air conditioning system through the vehicle's network bus (such as CAN bus or LIN bus). The vehicle network bus can connect various electronic control units (ECUs) in the vehicle so that they can exchange data and control signals. That is, the vehicle air conditioning system will periodically broadcast its working status, including but not limited to parameters such as the current air volume, target temperature value, and actual temperature value.

[0038] Specifically, the vehicle's air conditioning control unit encapsulates the current operating status, such as the airflow rate and the actual temperature inside the vehicle, into status messages. These messages are periodically broadcast or sent in response to requests via the network bus. The central processing module in the audio system listens to these status messages and parses out the airflow rate and current temperature value, providing a basis for subsequent volume adjustments and content recommendations.

[0039] As an alternative implementation, the system does not read data directly from the air conditioning system, but collects information through independent temperature and airflow sensors. The temperature and airflow sensors can be placed in appropriate locations inside the vehicle to accurately capture the current airflow and interior temperature.

[0040] Specifically, the temperature sensor is used to monitor the actual temperature inside the vehicle in real time, while the air volume sensor is used to detect the air volume when the air conditioner is blowing air. The central processing module receives data from the temperature sensor and the air volume sensor, processes it in real time, and extracts the current air volume and the temperature value inside the vehicle.

[0041] It is worth noting that by accurately obtaining the air volume and interior temperature of the vehicle's air conditioning system directly or indirectly, the audio system can make precise volume adjustments and content recommendations based on the real-time status of the air conditioning, effectively eliminating the interference of air conditioning noise on hearing, enhancing the continuity of the experience, and improving the overall comfort of the driver and passengers.

[0042] Step S104: Determine the target volume value of the car audio system based on a preset function and the current airflow rate, wherein the preset function is used to determine the functional relationship between the current airflow rate and the target volume value.

[0043] In the technical solution provided in step S104 of the present invention, the preset function adopts the form of a piecewise linear function. The function is calibrated in advance based on experimental data or user feedback to ensure that the adjustment of the volume value under different airflow conditions meets the requirements of auditory comfort.

[0044] Specifically, for example, when the airflow value ranges from 0% to 100%, the preset function can be defined as:

[0045] Volume_Gain = f(Fan_speed)

[0046] When the airflow is between 0% and 30%, the volume gain is 0dB, meaning the volume remains constant.

[0047] When the air volume is between 30% and 100%, the volume gain increases linearly with the air volume, reaching a maximum of +6dB.

[0048] As another alternative implementation, the preset function can be determined by a trained machine learning model based on a large amount of historical dataset, including wind noise levels under different airflow conditions and users’ volume adjustment behavior under these conditions. The model is trained using deep learning techniques (such as neural networks) and can output a target volume gain value corresponding to the current airflow. This gain value is more personalized and accurate and can better adapt to the auditory preferences of different users under different airflow conditions.

[0049] It is worth noting that by adjusting the volume gain in real time, the wind noise caused by changes in air conditioning airflow is effectively offset, ensuring that the audio content played in the car audio system can be heard clearly under various airflow conditions. At the same time, the automatic volume adjustment function reduces the need for drivers or passengers to frequently manually adjust the volume, thereby reducing the complexity of operation and improving driving safety.

[0050] Step S106: Determine the target playlist based on the numerical relationship between the current temperature value and the preset temperature value.

[0051] In the technical solution provided by step S106 of the present invention, the in-vehicle audio control system first needs to calculate the difference between the current temperature value and the preset temperature value, i.e., the temperature difference. This difference can be obtained by comparing the actual temperature collected by the temperature sensor with the ideal temperature set by the user through the in-vehicle central control screen. Based on the calculated temperature difference range, the system presets several playlists to correspond to it. For example, if the temperature difference is large (the absolute value exceeds a predetermined threshold), it indicates that the in-vehicle ambient temperature is far from the user's expectation. The system will select playlists with strong rhythms or quiet and soothing music to help the user alleviate discomfort or enhance the sensory experience through psychological suggestion. Conversely, if the temperature difference is small, the system may maintain the current playlist or select music with a peaceful melody to avoid unnecessary disturbance.

[0052] As an alternative implementation, the in-vehicle audio control system can collect and analyze user temperature preferences, music preferences, and the correlation between the two over a long period to build user profiles and understand user preferences for playlist types under specific temperature conditions. Furthermore, based on this data, a temperature difference-playlist recommendation model is trained using machine learning algorithms (such as deep neural networks). This model can predict and recommend the most suitable playlists for the current environment based on real-time temperature differences and the user's historical behavior. That is, after each temperature change, the system re-evaluates and recommends playlists using this model, reacting even to subtle temperature variations, thus providing a more personalized music experience.

[0053] Specifically, playlist mapping refers to the process of associating a specific temperature range with a playlist of a particular type or style. For example, a high temperature range might be mapped to a high-energy electronic music playlist, while a low temperature range might be mapped to a light and upbeat country music playlist.

[0054] It's worth noting that the music selection is synchronized with changes in the car's interior temperature, creating a more harmonious and immersive driving atmosphere and enhancing overall comfort. Furthermore, the playlist selection takes into account individual temperature preferences and musical tastes, providing a more personalized music experience and meeting the unique needs of different users under varying temperature conditions.

[0055] Step S108: Control the playback status of the car audio system according to the target playlist and target volume value.

[0056] In the technical solution provided by step S108 of the present invention, the central processing module sends the determined target playlist information to the control unit of the vehicle audio system. The latter loads the corresponding playlist tracks from local storage or online music service according to the received information. At the same time, after receiving the target volume value sent from the central processing module, the control unit will immediately adjust the current volume to the target value to ensure the appropriateness of the volume.

[0057] As an optional implementation, once the central processing module determines the target volume value based on the preset function and real-time airflow, and determines the target playlist based on the temperature difference, it generates corresponding control commands and sends them to the local control unit of the vehicle audio system via the vehicle's network bus (such as the CAN bus). Upon receiving the commands, the local control unit of the audio system parses the target volume value and playlist information, adjusts the volume, and begins playing the music or audio content from the target playlist.

[0058] As an alternative implementation, the central processing module sends the target volume value and target playlist information to the cloud server. The server parses the instructions and translates them into interface calls to the online music streaming service to retrieve and push music from the target playlist to the vehicle audio system. Upon receiving the control instructions from the cloud server, the vehicle audio system adjusts the volume to the target value and begins playing the specified playlist online, achieving seamless integration with cloud resources.

[0059] Specifically, the local control unit is a hardware module within the vehicle audio system responsible for decoding and amplifying audio signals and controlling various audio functions.

[0060] Specifically, cloud servers refer to server clusters located on the Internet that can provide access to a large number of online music resources and personalized customization services, and can be remotely controlled through network connections with car audio systems.

[0061] It's worth noting that the audio system responds instantly, adjusting to its optimal state to match the current in-car environment, quickly enhancing the user's driving and riding comfort. While adjusting the volume, it ensures that sound quality is not compromised, maintaining a high-quality listening experience. Furthermore, by selecting the music genre based on the ambient temperature, it creates a consistent and psychologically aligned auditory environment for the user, enhancing the intelligence of the audio system and the personalization of the user experience.

[0062] Steps S102 to S108 above show that, in this invention, the current airflow of the vehicle's air conditioning system and the current temperature value inside the target vehicle are obtained. Based on a preset function and the current airflow, the target volume value of the vehicle's audio system is determined. The preset function is used to determine the functional relationship between the current airflow and the target volume value. This achieves the purpose of determining the target playlist based on the numerical relationship between the current temperature value and the preset temperature value. Thus, it achieves the technical effect of controlling the playback status of the vehicle's audio system based on the target playlist and the target volume value. This solves the technical problem in the prior art where the vehicle's audio system cannot respond to changes in the status of the vehicle's air conditioning system, resulting in low intelligence of the vehicle's audio system.

[0063] The method described in this embodiment will now be described in further detail.

[0064] Step S1041: Determine the current air volume level, where the air volume level includes a first level and a second level, and the air volume of the first level is lower than that of the second level.

[0065] Step S1042: In response to the current air volume setting being the first setting, the first volume value is determined as the target volume value based on a preset function.

[0066] Step S1043: In response to the current air volume setting being the second setting, the second volume value is determined as the target volume value based on a preset function, wherein the second volume value is greater than the first volume value.

[0067] In this embodiment, the central processing module receives airflow information from the vehicle's air conditioning system. First, it determines which preset airflow level the current airflow belongs to. Airflow levels can be pre-divided into a first level and a second level, where the first level corresponds to a lower airflow and the second level corresponds to a higher airflow. This division of airflow levels can be based on empirical data or user feedback to determine key thresholds related to the relationship between airflow and wind noise, aiming to differentiate the impact levels of different airflow levels on the auditory experience. Furthermore, if the current airflow level is determined to be the first level, it means the airflow of the air conditioning system is at a low level. At this time, the system calculates a first volume value matching the low airflow environment based on a preset volume adjustment function and sets it as the target volume value. The first volume value adjustment is usually relatively gentle, aiming to maintain the original auditory balance inside the vehicle and avoid unnecessary volume increases in low airflow environments, thereby saving energy and maintaining comfort.

[0068] Furthermore, when the fan speed is determined to be at the second level, the audio control system recognizes that the current fan speed is at a high level, which may generate significant wind noise and affect the listening experience. In this case, the system again uses a preset function to calculate a second volume value adapted to the high fan speed environment, which serves as the target volume value. The second volume value is greater than the first volume value to compensate for wind noise and ensure that the user can still clearly hear the content played by the audio system.

[0069] As an optional implementation, the preset function is a rule that determines the volume gain based on a linear or non-linear mapping of the fan speed setting. For example, for the first setting, the volume gain might be set to 0dB, while for the second setting, the gain might increase to +3dB or more to accommodate changes in wind noise.

[0070] As an alternative implementation, the preset function can be a trained machine learning model that predicts the optimal volume gain based on historical datasets, including wind noise levels at different fan speeds and user volume adjustment preferences.

[0071] It is worth noting that the audio volume can quickly adapt to changes in air conditioning airflow, eliminating or reducing wind noise interference with hearing and significantly improving driving comfort. At the same time, since the volume adjustment is based on the precise determination of the airflow level, it avoids excessive or insufficient volume adjustment, achieving precise and meticulous volume control.

[0072] Step S1061: Compare the current temperature value with the preset temperature value to obtain the comparison result;

[0073] Step S1062: In response to the comparison result indicating that the current temperature value is greater than the preset temperature value, the target playlist is determined to be the first preset playlist;

[0074] Step S1063: In response to the comparison result indicating that the current temperature value is less than the preset temperature value, the target playlist is determined to be the second preset playlist;

[0075] Step S1064: In response to the comparison result indicating that the current temperature value is equal to the preset temperature value, the target playlist is determined to be the third preset playlist.

[0076] In this embodiment, the central processing module acquires the real-time current temperature value and the user-set preset temperature value, compares the values, and determines the temperature difference. This action can be achieved through real-time monitoring by a temperature sensor and temperature settings on the user interface. The comparison result may be that the current temperature is higher than, lower than, or equal to the preset temperature. Furthermore, if the current temperature value is greater than the preset temperature value, it indicates that the interior environment is hot. Based on the comparison result, the system determines the target playlist as the first preset playlist. This type of playlist typically contains music with a cooling effect, such as ocean waves or piano music, to help the user feel cooler through psychological suggestion.

[0077] Furthermore, if the current temperature is lower than the preset temperature, meaning the car interior is too cold, the system will respond to the comparison result by setting the target playlist as the second preset playlist. This type of playlist may be more inclined to warm and energetic music styles, such as rock and electronic dance music, in order to enhance the warm atmosphere inside the car.

[0078] In addition, if the current temperature value is equal to the preset temperature value, it means that the temperature inside the car has reached the user's set comfortable temperature. At this time, the system will determine the target playlist as the third preset playlist. These playlists are usually moderate in style and not too stimulating. They are designed not to disturb the calm state of the driver and passengers and provide a background music level listening experience.

[0079] As an optional implementation, the selection of preset playlists is based on a fixed set of temperature range and music style mapping rules. For example, if the current temperature is higher than the preset temperature, the "cooling" playlist with natural element sounds is selected (first preset playlist); when the temperature is lower than the preset value, the "warm" playlist with a faster tempo and enthusiastic melody is played (second preset playlist); and when the temperature is equal, the "comfortable" playlist with a soft and stable sound is played (third preset playlist).

[0080] As another alternative implementation, playlist selection is not only based on temperature comparison results, but also takes into account the user's historical listening history and preferences. For example, if a user prefers to listen to pop music rather than the natural sounds in a traditional "cooling" playlist when the temperature is too high, the system will learn and remember this preference, and will prioritize recommending pop music under similar conditions in the future. Such personalized adjustments can be achieved by analyzing user behavior data and feedback mechanisms, making playlist selection more closely aligned with the user's actual needs.

[0081] It's worth noting that the system automatically adjusts the playlist based on temperature differences, creating a more harmonious and comfortable psychological atmosphere for drivers and passengers, whether the environment is too hot, too cold, or comfortable. Furthermore, through intelligent adjustments to music playback, it not only addresses physical temperature discomfort but also influences emotions through the emotional tone of the music, achieving a dual optimization of comfort.

[0082] Step S10621: Calculate the first difference between the current temperature value and the preset temperature value;

[0083] Step S10622: In response to the first difference being greater than the first preset threshold, the target playlist is determined to be the first preset sub-playlist;

[0084] Step S10623: In response to the first difference being less than the first preset threshold, the target playlist is determined to be the second preset sub-playlist, wherein the music types of the first preset sub-playlist and the second preset sub-playlist are different.

[0085] In this embodiment, the central processing module obtains the current temperature value and the preset temperature value set by the user, and calculates the difference between the two, namely the first difference. The above calculation can be based on real-time temperature sensor data and the target temperature set by the user through the vehicle central control screen. The purpose is to quantify the degree of deviation between the vehicle interior temperature and the user's expected temperature.

[0086] Furthermore, if the first difference is greater than the first preset threshold, it indicates a significant gap between the in-car temperature and the user's desired comfort level. In this case, the system will determine the target playlist as the first preset sub-playlist based on this comparison result. This type of playlist usually has a more pronounced emotional tone, using psychological suggestion to help the user adapt to the ambient temperature. For example, in hot weather, the first preset sub-playlist may include cool natural sound effects, electronic music, etc., to alleviate the discomfort caused by high temperatures.

[0087] Furthermore, if the first difference is less than the first preset threshold, but still indicates a certain degree of deviation in the car's interior temperature, the system selects the second preset playlist as the target playlist. This type of playlist differs in music genre from the first preset playlist, but still aims to enhance the user experience through the emotional tone of the music. For example, in a mildly overheated environment, the second preset playlist might include gentle, melodious light music to soothe the user's emotions in a more subtle way.

[0088] As an optional implementation, the system presets a first threshold for the temperature difference, such as 5°C, as the basis for distinguishing between the first preset playlist and the second preset playlist. When the temperature difference is greater than the threshold, the system automatically switches to the first preset playlist, which has a stronger emotional tone; when the temperature difference is less than the threshold, it selects the second preset playlist, which has a more restrained emotional expression.

[0089] It is worth noting that the playlist selection is instantaneous, which ensures that the music genre matches the in-car temperature environment in real time.

[0090] As an alternative implementation, the first preset threshold may not be fixed, but dynamically adjusted based on real-time user feedback and historical preferences. For example, if most users still report discomfort when the temperature difference is 4°C, the system will automatically lower the threshold to 4°C to trigger playlist adjustments earlier. Simultaneously, the selection of the first and second preset sub-playlists will also be based on user preference data. For instance, a user might prefer listening to classical music when the temperature difference is large; the system will learn and intelligently select sub-playlists based on this preference.

[0091] It's worth noting that, based on a precise comparison of the temperature difference with preset thresholds, the system automatically plays a playlist that matches the current temperature difference, improving the harmony between music playback and the in-car temperature environment and enhancing the comfort of passengers. Furthermore, the selection of music genres considers not only the magnitude of the temperature difference but also its severity, providing users with a more personalized emotional adjustment service through differentiated playback of the first and second preset sub-playlists.

[0092] Step S10631: Calculate the second difference between the preset temperature value and the current temperature value;

[0093] Step S10632: In response to the second difference being greater than the second preset threshold, the target playlist is determined to be the third preset sub-playlist;

[0094] Step S10633: In response to the second difference being less than the second preset threshold, the target playlist is determined to be the fourth preset sub-playlist, wherein the music types of the third preset sub-playlist and the fourth preset sub-playlist are different.

[0095] In this embodiment, the central processing module performs a subtraction operation on the current temperature value (provided by the vehicle temperature sensor) and the preset temperature value (the target temperature value set by the user through the vehicle interface) to obtain a second difference value. The above calculation can be used to quantify the degree of deviation between the in-vehicle temperature and the expected value.

[0096] Furthermore, when the second difference (the difference between the preset temperature value and the current temperature value) is greater than the second preset threshold, the system recognizes that the interior temperature is significantly lower than the user-set comfort temperature. This may occur in cold weather or when the air conditioning is over-cooling. In response to this state, the system determines the target playlist as the third preset sub-playlist. These playlists typically have lively and warm musical characteristics, such as rock and pop music, aiming to give the user a warm feeling psychologically and enhance the driving experience.

[0097] Furthermore, if the second difference is less than the second preset threshold, but still indicates that the interior temperature is lower than the preset value, this may occur in cool weather or when the air conditioning is only slightly cooling. In this case, the system sets the target playlist to the fourth preset sub-playlist. This type of playlist has a different music genre than the third preset sub-playlist; it may contain light and energetic pop music or folk songs, aiming to regulate the user's mood in a gentler way and avoid overly strong warm cues.

[0098] As an optional implementation, by pre-setting a second preset threshold, such as 3°C, when the interior temperature is more than 3°C lower than the preset temperature, the system automatically selects and plays a third preset playlist; if the temperature difference is less than 3°C but there is still a temperature deviation, the system will play a fourth preset playlist. This method provides an immediate and intuitive response mechanism that can quickly adjust the playback content according to the temperature difference.

[0099] As an alternative implementation, the second preset threshold is not fixed but dynamically adjusted based on real-time user feedback and historical preferences. For example, if the system detects that a user feels cold when the temperature difference is 2°C, the threshold can be automatically lowered to 2°C to initiate the playback of warm-toned playlists earlier. Simultaneously, the selection of the third and fourth preset sub-playlists also considers the user's preference for specific music genres. For instance, someone might prefer listening to classical music in cold weather; the system will learn this preference and prioritize playing the corresponding third preset sub-playlist under similar conditions in the future.

[0100] It's worth noting that by playing specific types of music that match the degree of temperature deviation inside the car, the system leverages the emotional tone of the music to influence the user's mood, providing emotional temperature regulation assistance. Simultaneously, it dynamically adjusts playlist selections based on user preferences, ensuring that music types better suit the user's individual tastes in different temperature environments, enhancing the personalization of the driving experience. Furthermore, it instantly responds to differences between the car's interior temperature and the preset temperature, quickly adjusting the in-car atmosphere through music selection to improve user comfort.

[0101] Step S110: Obtain the user needs of the target user;

[0102] Step S112: In response to user requests, including user playlists and user volume values, control the playback status of the car audio system based on the user playlists and user volume values.

[0103] In this embodiment, the system collects information about the user's playlist selections and volume preferences through the in-vehicle touchscreen display, voice recognition module, or other user interaction interfaces. This step may involve direct user input (such as selecting a specific playlist via the touchscreen or adjusting the volume using voice commands) or indirect inference based on the user's historical behavior data (such as the system learning the user's frequently used playlist types and volume settings). Furthermore, when the system recognizes that the user's request includes specific playlists and volume values, it will immediately adjust the playback status of the in-vehicle audio system to match these requests.

[0104] For example, the system will load a user-specified playlist and adjust the volume to the user-specified value. This control action is instantaneous and accurately reflects the user's needs, ensuring that drivers and passengers receive the most satisfying auditory experience.

[0105] As an alternative implementation, users can directly select the playlist they want to listen to and adjust the volume via the menu on the in-vehicle touchscreen. Once the system receives these inputs, it immediately updates the audio system's playlist and volume settings.

[0106] As an alternative implementation, users can make requests through voice dialogue with the in-vehicle AI assistant, such as saying, "Play my favorite playlist, turn the volume up to 70%." After receiving the voice command, the system uses voice recognition technology to convert it into an executable control command, loads the correct playlist, and adjusts the volume to the set value.

[0107] It is worth noting that steps S110 to S112 ensure that the music type and volume level played by the car audio system perfectly match the user's personal preferences, improving the audio entertainment experience satisfaction of drivers and passengers. At the same time, the system can quickly identify and execute user-submitted playlist selection and volume adjustment commands, reducing waiting time and enhancing the immediacy and smoothness of the user experience.
