Technical Field

[0001] This invention relates to the field of status reminder technology, and in particular to a vehicle status reminder method, device, and electronic device based on dynamic music adjustment. Background Technology

[0002] Currently, vehicles primarily provide status alerts via dashboard icons and a single beep. Icon alerts require active viewing by the driver and are easily missed in complex road conditions or when the driver is focused; the beeping sound is monotonous and lacks differentiation, making it difficult for drivers to quickly distinguish specific alarm types (such as an unclosed door or a blind spot warning) by sound. Both methods suffer from being unintuitive, having low recognition, and significantly interfering with driving, thus impacting driving safety and user experience. Summary of the Invention

[0003] In view of this, the purpose of the present invention is to provide a vehicle status reminder method, device and electronic device based on dynamic music adjustment, which maps the vehicle status by dynamically adjusting the music parameters, making the reminder more intuitive, highly recognizable and naturally integrated into the driving environment, thereby greatly improving the efficiency of status perception and driving safety.

[0009] In a preferred embodiment of the present invention, the above-mentioned real-time adjustment of the music currently playing in the vehicle based on the music adjustment strategy further includes: selecting a corresponding adjustment execution strategy based on the state risk level; if the state risk level is a first level, the first strategy is used to perform the adjustment; the first strategy enables the audio parameters to smoothly transition to the target value within a first time period; if the state risk level is a second level higher than the first level, the second strategy is used to perform the adjustment; the second strategy prioritizes the adjustment of key audio parameters and completes the adjustment within a second time period shorter than the first time period.

[0010] In a preferred embodiment of the present invention, after acquiring the current status information of the vehicle in real time, the method further includes: determining whether the current status information indicates a status type that needs to be continuously monitored; if the current status information indicates a status type that needs to be continuously monitored, then the following steps are executed repeatedly until the status type is detected to be removed: acquiring the current status information of the vehicle in real time; generating a corresponding music adjustment strategy based on the current status information; and adjusting the music currently being played in the vehicle in real time based on the music adjustment strategy.

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Currently, in-car music primarily serves as an entertainment resource for users, with its core function being to provide audio content services. Its application in expanding vehicle functionality is relatively limited. In the area of ​​vehicle status alerts, existing technologies mostly employ screen status indicators (such as instrument panel status icons) and sound alerts (such as a single buzzer alarm sound). Icon alerts require users to actively check the screen, which may lead to missed important vehicle reminders while driving. A single buzzer alarm sound is rather monotonous, and the differences in sound between different vehicle states are minimal, sometimes making it difficult for users to quickly and accurately distinguish between different vehicle states and to take timely action, thus impacting driving safety and user experience.

[0021] Based on this, the present invention provides a vehicle status reminder method, device, and electronic device based on dynamic music adjustment. This method can acquire the vehicle's current status information in real time, generate a corresponding music adjustment strategy based on the current status information, and adjust the currently playing music in real time based on the music adjustment strategy to generate a sound effect output that integrates status reminder information. After the status indicated by the current status information is cleared, the music is controlled to return to its pre-adjustment state or transition to a new baseline state. In this method, the vehicle status is mapped through dynamic adjustment of music parameters, making the reminders more intuitive, highly recognizable, and naturally integrated into the driving environment, significantly improving status perception efficiency and driving safety.

[0022] To facilitate understanding of this embodiment, a detailed description of a vehicle status reminder method based on dynamic music adjustment disclosed in this embodiment of the invention will be provided first.

[0023] Example 1 This invention provides a vehicle status reminder method based on dynamic music adjustment. Figure 1 This is a flowchart illustrating a vehicle status alert method based on dynamic music adjustment, provided as an embodiment of the present invention. Figure 1 As shown, the vehicle status reminder method based on dynamic music adjustment may include the following steps: Step S101: Obtain the current status information of the vehicle in real time.

[0024] The current status information refers to a set of digital data collected in real time through vehicle buses (such as CAN, LIN, Ethernet) and various sensors, which can reflect the vehicle's operating status, driver behavior, or vehicle body status.

[0025] Data can be obtained through vehicle speed sensors, acceleration sensors, wheel speed sensors, etc., such as vehicle speed: 120km / h (speeding) and longitudinal acceleration: -0.5G (emergency braking).

[0026] Among them, driver behavior can be obtained through in-vehicle cameras (for driver facial recognition and eye tracking), steering wheel grip force sensors, or wearable devices, and after being processed by algorithms, fatigue levels such as high and distracted are obtained.

[0027] The vehicle's status can be obtained through the Body Control Module (BCM), such as: left rear door: not closed tightly, fuel tank level: low.

[0028] In particular, by acquiring the vehicle's current status information in real time, a real-time and diverse data input foundation can be provided for the entire method.

[0029] Step S102: Generate a corresponding music adjustment strategy based on the current state information.

[0030] Among them, the music adjustment strategy is a set of instructions or parameter package that includes "what to do" and "how to do it", and it is a bridge connecting vehicle status and music changes.

[0031] For example, after receiving the status information "Fatigue Level: High", the system might generate a strategy such as "switching the music style to more energetic rock music and appropriately increasing the volume and rhythm to have an invigorating effect." This transforms abstract vehicle status information into specific, executable audio operation commands.

[0032] Step S103: Adjust the music currently playing in the vehicle in real time based on the music adjustment strategy to generate sound effect output that incorporates status reminder information.

[0033] Among them, the sound output that integrates status reminder information refers to the sound that the end user hears through the car audio system. It retains the enjoyment of the original music and encodes status information through specific audio feature changes (such as rhythm, timbre, and spatial sense).

[0034] Continuing with the example of fatigued driving, the system might: 1) invoke the API of the audio processing chip (DSP) to boost the bass gain and overall loudness of the music in real time; 2) or, fade in a fast-paced drum track into the background music. The user will feel the music suddenly become more powerful and impactful, thus subconsciously waking them up. This achieves non-intrusive, intuitive status alerts, improving driving safety and experience.

[0035] Step S104: After the current status information indicates that the status has been cleared, control the music to return to the state before adjustment or transition to a new reference state.

[0036] Among them, "state deactivation" refers to the disappearance of the conditions that triggered the reminder, such as the car door being closed or fatigue being relieved. "Resumption" or "transition" reflects the system's adaptability and user-friendliness.

[0037] For example, when the system detects that the driver's fatigue has subsided (e.g., confirmed by a camera that their gaze has returned to focus), it initiates a 5-10 second audio fade-out process, smoothly restoring the music parameters from an energetic state to a more soothing one, or automatically playing the next suitable song based on the user's playlist. This avoids the discomfort caused by abrupt changes in music after the reminder ends, maintaining a consistent user experience.

[0038] Furthermore, after acquiring the vehicle's current status information in real time, the method also includes: determining whether the current status information indicates a status type that needs to be continuously monitored; if the current status information indicates a status type that needs to be continuously monitored, then the following steps are executed repeatedly until the status type is detected to be removed: acquiring the vehicle's current status information in real time; generating a corresponding music adjustment strategy based on the current status information; and adjusting the music currently playing in the vehicle in real time based on the music adjustment strategy.

[0039] The system internally labels state types. For example, "low fuel" and "fatigue driving" are labeled as requiring continuous monitoring, while "turn signal on" may not. The judgment logic can be based on whether the state has "persistence" and "risk accumulation".

[0040] For example, "fatigue driving": Upon initial detection of fatigue, the system triggers a music adjustment (e.g., increasing the intensity). A continuous monitoring loop then begins, analyzing the driver's state again via camera at regular intervals (e.g., every 30 seconds). If fatigue persists, the system may not repeat the same adjustment (to avoid distraction), but can introduce new, progressive reminders. For example, after 3 minutes, in addition to increasing the intensity of the music, a subtle, rhythmic heartbeat sound effect can be added to reinforce the psychological suggestion. Once the system detects that the driver has regained consciousness (e.g., blinking forcefully, adjusting posture), the fatigue is considered relieved, the music is restored, and the continuous monitoring loop is exited. This approach handles complex and dynamically changing vehicle states, providing a progressively intelligent and immersive interactive experience, rather than a simple, one-off response.

[0041] The vehicle status alert method based on dynamic music adjustment provided in this invention, through a method, device, and electronic device, can acquire the vehicle's current status information in real time, generate a corresponding music adjustment strategy based on the current status information, and adjust the music currently playing in the vehicle in real time based on the music adjustment strategy to generate a sound effect output that integrates status alert information. After the status indicated by the current status information is cleared, the music is controlled to return to the state before adjustment or transition to a new baseline state. In this method, the vehicle status is mapped by dynamically adjusting the music parameters, making the alerts more intuitive, highly recognizable, and naturally integrated into the driving environment, significantly improving status perception efficiency and driving safety.

[0042] Example 2 This invention also provides another vehicle status reminder method based on dynamic music adjustment; this method is implemented based on the method in the above embodiments; the method focuses on describing the specific implementation of generating a corresponding music adjustment strategy based on the current status information.

[0043] Figure 2 A flowchart of another vehicle status reminder method based on dynamic music adjustment provided in an embodiment of the present invention is shown below. Figure 2 As shown, the music adjustment strategy generated based on the current state information may include the following steps: Step S201: Based on the current state information, identify at least one target vehicle state type.

[0044] The target vehicle state type is the result of semantic and categorized processing of the original state information. The system maintains a state type dictionary, for example: {"speeding", "fatigue driving", "door not closed", "low fuel", "following too closely"}.

[0045] For example, when the system receives data such as "vehicle speed: 130 km / h, current road speed limit: 120 km / h", it identifies it as "speeding" using rule-based judgment or a lightweight model. Simultaneously, the system supports concurrent recognition of multiple states, such as simultaneously identifying "speeding" and "fatigue driving". This transforms low-level data into high-level, understandable "events," laying the foundation for subsequent differentiated processing.

[0046] Step S202: Determine the state risk level corresponding to the target vehicle state type.

[0047] The status risk level is a quantitative classification of the potential security risks or urgency that the status may pose to the user. For example, it can be divided into low risk (alert), medium risk (warning), and high risk (alert).

[0048] For example, the basic mapping relationship could be: an open door corresponds to low risk; low fuel corresponds to medium risk; and a forward collision warning corresponds to high risk. This level is the core basis for subsequently selecting different adjustment intensities (such as the magnitude of volume change) and execution speeds.

[0049] Specifically, determining the state risk level corresponding to the target vehicle state type may include: obtaining the basic risk level corresponding to the target vehicle state type; analyzing the state intensity parameter or state duration parameter in the current state information; and dynamically correcting the basic risk level based on the state intensity parameter or state duration parameter to obtain the final state risk level.

[0050] The system directly reads the basic risk level corresponding to the target vehicle's status type from a preset mapping table. For example, the basic risk level for "fatigue driving" is "medium risk".

[0051] Among them, the state intensity parameter is a quantitative value used to describe the severity of the state, and this dynamic parameter can be parsed from the original current state information.

[0052] For example, for "speeding", the intensity parameter could be "the percentage of speeding exceeded"; for "lane departure", it could be "the distance of deviation from the center line".

[0053] The duration parameter refers to the time that the state has lasted. For example, the "fatigue driving" state has lasted for 2 minutes.

[0054] Among them, when dynamically correcting the basic risk level based on the state intensity parameter, if the basic risk level of speeding is medium risk, but speeding of 50% (high intensity) is detected, it will be dynamically corrected to high risk.

[0055] Specifically, when dynamically adjusting the basic risk level based on the duration of the state, if the basic risk level for fatigued driving is medium risk, but the state is continuously monitored for more than 5 minutes, it will be dynamically adjusted to high risk. A duration threshold table can be set, for example: less than 2 minutes is medium risk, 2-5 minutes is medium-high risk, and more than 5 minutes is high risk.

[0056] This enables tiered early warning systems. For the same type of problem, different intensities of musical alerts are provided based on their severity, significantly improving the system's intelligence and user experience.

[0057] Step S203: Based on the target vehicle state type and state risk level, a target music adjustment mode is matched from multiple pre-set music adjustment modes to form a music adjustment strategy.

[0058] The music adjustment mode is a predefined, parameterized audio processing template. Each mode is associated with one or more combinations of (state type, risk level) and defines the specific audio modification method.

[0059] For example, the system database contains a pattern library, pattern A (used for "fatigue driving, medium risk"): {"action": "change_style"", "target_style": "upbeat_rock", "volume_increment": 10%}.

[0060] Mode B (for "speeding, high risk"): {"action": "insert_alert", "alert_id": "urgent_beep", "priority": "immediate", "volume_override": 80%}.

[0061] This allows for quick matching via table lookup or rule engine, enabling the configuration of complex "state-sound effect" mapping relationships, making the system easy to manage and iterate.

[0062] The vehicle status reminder method based on dynamic music adjustment provided in this invention introduces a three-layer decision architecture of status type identification, risk assessment, and pattern matching, making the strategy generation process more intelligent and structured.

[0063] Example 3 This invention also provides another vehicle status reminder method based on dynamic music adjustment; this method is implemented based on the method in the above embodiments; the method focuses on describing the specific implementation of real-time adjustment of the music currently playing in the vehicle based on the music adjustment strategy.

[0064] Figure 3 A flowchart of another vehicle status reminder method based on dynamic music adjustment provided in an embodiment of the present invention is shown below. Figure 3 As shown, this music adjustment strategy for real-time adjustment of the music currently playing in the vehicle may include the following steps: Step S301: Obtain the baseline information of the currently playing music.

[0065] Among them, the baseline information is a snapshot of the music state before adjustment, which is the reference zero point for calculating the adjustment amount.

[0066] The baseline information may include: the raw metadata of the current track (BPM - beats per minute, key, genre), the spectral characteristics of the real-time audio stream, the current playback volume, equalizer (EQ) settings, sound field center position, etc. This information can be obtained through the audio player interface and digital signal processing (DSP) module.

[0067] Step S302: Based on the target music adjustment mode, determine at least one audio parameter to be adjusted and the target value corresponding to the audio parameter.

[0068] Among these, audio parameters are low-level control variables that can be directly modified by the car audio system or DSP. Target values ​​are the new values ​​that these parameters need to achieve.

[0069] The audio parameters include at least one of the following: playback rate, volume, equalizer parameters, and sound field positioning parameters.

[0070] Playback rate is used to change the speed at which music is played, thus altering the rhythm. The target value can be a percentage (e.g., speeding up by 10%).

[0071] The most direct way to indicate volume is by setting a target value. This target value can be an absolute decibel level or an increment relative to a base volume.

[0072] The equalizer parameters are used to adjust the gain of different frequency bands (bass, midrange, and treble). For example, boosting the bass (e.g., increasing the gain of the 100Hz band by 3dB) can create a sense of urgency; boosting the treble (e.g., increasing the gain of the 5kHz band) can enhance penetration and alertness.

[0073] Among them, the sound field localization parameter is used to control the virtual position of sound within the carriage. For example, the sound image of a prompt sound effect or a specific musical instrument can be located near the driver's headrest speaker to achieve directional reminders.

[0074] This translates the high-level music adjustment modes into low-level control commands that the audio system can execute.

[0075] Step S303: Adjust the music currently playing in the vehicle in real time based on the audio parameters to be adjusted and the target value.

[0076] The system calls audio middleware or DSP drivers to write the target values ​​of the above parameters into the corresponding hardware registers or apply real-time processing effects through the software audio pipeline. Ultimately, this achieves perceptible changes in the music for the user.

[0077] Specifically, real-time adjustment of the music currently playing in the vehicle based on the audio parameters to be adjusted and the target value may include: when the target music adjustment mode indicates that a reminder sound effect needs to be inserted, selecting a reminder audio segment corresponding to the target vehicle status type from a pre-set reminder sound effect library; determining the mixing rules between the reminder audio segment and the currently playing music; the mixing rules include the insertion timing, mixing ratio, and transition effects; and performing sound effect insertion and mixing processing based on the mixing rules.

[0078] The alert sound effects library is a database that stores carefully designed short audio files (such as ".wav" and ".mp3"). Each audio clip is designed with the integration with the music and semantic expression in mind.

[0079] For example, a simple, rhythmic "ding-dong" sound can be designed for the "seatbelt not fastened" status, with its tone matching the key of the currently playing music; a "whoosh" sound can be designed for the "blind spot alarm" that smoothly sweeps from one side to the other to simulate the location of the risk.

[0080] Among them, the corresponding audio file can be indexed according to the target status type (such as "car in the left rear blind spot").

[0081] Among them, the mixing rules define the technical parameters of how newly inserted sound effects can coexist with background music.

[0082] This includes calculating the phase of the current music beat and inserting sound effects at the beat points to enhance rhythmic uniformity and avoid abruptness, thus determining the timing of the insertion.

[0083] This feature allows you to control the volume of the alert sound effects relative to the background music volume, thus determining the mixing ratio. In high-risk situations, the sound effect volume can be skipped or the background music can be lowered.

[0084] Regarding transition effects: apply fade-in, fade-out, or cross-fade effects to make the insertion and removal process smooth.

[0085] This process can be performed by an audio rendering engine or a mixer. The audio stream for the alert sound effects is synthesized in real-time from the background music audio stream according to mixing rules, and the final mixed audio signal is output to the amplifier and speakers.

[0086] Furthermore, the real-time adjustment of the music currently playing in the vehicle based on the music adjustment strategy may also include: selecting the corresponding adjustment execution strategy based on the state risk level; if the state risk level is the first level, the first strategy is used to perform the adjustment; the first strategy enables the audio parameters to smoothly transition to the target value within a first time period; if the state risk level is the second level, which is higher than the first level, the second strategy is used to perform the adjustment; the second strategy prioritizes the adjustment of key audio parameters and completes the adjustment within a second time period shorter than the first time period.

[0087] The system's internal policy selector switches to different execution code paths based on the final risk level (such as low, medium, or high).

[0088] The first strategy targets low-risk and medium-risk individuals.

[0089] For commands like "increase volume by 10%", the change isn't instantaneous. Instead, it's achieved gradually over a "first time period" (e.g., 3 seconds) using a linear or exponential curve, gradually increasing the volume from the current value to the target value. Adjustments to parameters such as the equalizer and sound field also employ a gradual approach. The changes are subtle and imperceptible, suitable for comfort and informational alerts (such as when the air conditioning temperature reaches a set value), minimizing disruption to the driving experience.

[0090] The second strategy targets high-risk situations.

[0091] For high-risk scenarios (such as pre-collision), the system identifies key audio parameters, typically volume (to ensure the alert is heard) and channel priority for inserting the alarm sound. The system immediately interrupts the fading process, raising the main volume to a safely audible level within a very short "second time period" (e.g., 0.5 seconds), and plays the collision warning sound with the highest priority. Other non-critical parameters (such as style switching) may be delayed or not executed at all. This ensures that the "mandatory" and "immediate" nature of the audio alert is guaranteed in emergency situations, with safety alerts taking priority over entertainment.
