Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of intelligent automobiles, and particularly relates to a unified management and linkage control method and system for simulation sound effects of electric vehicles. BACKGROUND

[0002] With the rapid development of the electric vehicle market, the mute characteristics of vehicles bring comfort while weakening the driving participation and intuitive operation feedback provided by the mechanical sound of traditional fuel vehicles. In order to improve the driving pleasure, make up for the lack of sound feedback, and create a unique auditory identity for the brand, vehicle simulation sound effect technology has become an important human-machine interaction function in the field of intelligent electric vehicles. Popularization of multi-mode simulation sound waves: Currently, medium and high-end electric vehicles generally have multiple selectable simulation sound waves to simulate different styles of sound experience. For example, the "sporty sound" and "theater mode" sound effects provided by the BMW i series models (see the BMW official website iDrive system function introduction); the "Audi e-tron sporty sound" of the Audi e-tron model (see the Audi China official website, vehicle configuration table). These sound effects are usually simply associated with the driving mode (such as sport, comfort, economy) or vehicle speed / motor speed of the vehicle, and provide different auditory atmospheres for the driver during driving. Preliminary application of scene-based sound effect prompts: In addition to driving sound waves, some models have begun to try to apply specific sound prompts to more diverse interactive scenarios. For example, Tesla vehicles emit a short prompt sound when shifting into gear (D or R); NIO vehicles have brand-specific sound effects in scenarios such as unlocking and charging (see NIO APP user manual). These sound effects are mainly used for status notification and function confirmation.

[0003] The existing patent application CN113978430A (named "a vehicle sound control method, device and vehicle") discloses a technology that switches different preset sound schemes according to vehicle working conditions (such as acceleration, deceleration, and steering). The core of this technology is to match the vehicle sound with dynamic driving behavior to improve the driving experience. However, through analysis of existing technology and products, it can be found that the existing simulation sound effect application has obvious functional fragmentation and lack of systematization. Specifically, the driving simulation sound wave, interactive prompt sound, and multi-sensory linkage function are usually developed independently and triggered independently. When the user selects a certain "sport sound wave", this sound wave theme only takes effect when the vehicle is accelerating. When the user performs operations such as stepping on the accelerator pedal and switching driving modes in the parked state, the feedback sound (if any) emitted by the vehicle is the system default, and the general sound effect is irrelevant to the selected sound wave style. This means that the existing technology fails to provide a top-level, unified management framework to intelligently bind and link the vehicle's existing multiple sound effect resources (sound wave library, prompt sound library) with the rich interactive scenarios (especially non-driving scenarios) in the cabin and multi-sensory devices (ambient light, seat).

[0004] This technical status leads to fragmentation of user experience and cannot form a complete, unified, and customizable brand interaction experience package, limiting the further exploration of the emotional value and brand value of simulation sound effect technology. This existing solution has significant defects: 1. Sound effect switching is isolated and disconnected from the scene: sound wave switching only affects the acceleration sound effect during driving, and for driver operations in the parked state (such as stepping on the accelerator or brake pedal), the vehicle usually has no feedback or the feedback is irrelevant to the selected sound wave style (such as a uniform "ding" sound), resulting in fragmentation of the sound effect experience at key interaction nodes.

[0005] 2. Lack of top-level unified management: the existing system is "one switch controls one sound effect". When the vehicle involves multiple scenarios that require sound effect feedback (such as driving sound and interactive prompt sound), these sound effects may come from different, unrelated audio sources, making it impossible to ensure that users receive a consistent style and complete experience of the sound effect theme at all touch points.

[0006] 3. Failure to form multi-sensory coordination: the simulation sound wave system usually operates independently and lacks deep linkage with in-vehicle ambient lights, seats, and other functions, making it impossible to create an immersive and themed cabin experience.

[0007] Therefore, there is a need for a solution that can systematically integrate and intelligently schedule existing simulation sound effects for vehicles. SUMMARY

[0008] The application aims to provide a unified management and linkage control method and system for electric vehicle simulation sound effects.

[0009] To achieve the above-mentioned purpose, the application adopts the following technical solutions: In the first aspect, the application provides a unified management and linkage control method for electric vehicle simulation sound effects, comprising: Obtaining a user response, determining a current global effective mode from a plurality of preset sound effect modes according to the user response; obtaining a vehicle state signal in real time, and identifying a specific interaction scene where the vehicle is currently located according to a preset determination condition; According to the current global effective mode and the specific interaction scene, querying a scene-feedback rule set pre-associated with the sound effect mode to obtain a feedback rule; Based on the feedback rule, the sound effect system of the vehicle and at least one linkage device are uniformly controlled to perform corresponding feedback actions; and returning to obtaining the vehicle state signal in real time after the execution is completed.

[0023] The drawings accompanying the specification of the present application serve to provide a further understanding of the present application, the illustrative embodiments thereof and its description serve to explain the present application and do not constitute an improper limitation thereof. In the drawings: Figure 1 The method flowchart of the embodiment of the present application; Figure 2 The overall architecture schematic diagram of the embodiment of the present application; Figure 3 The specific scene execution flowchart of the embodiment of the present application; Figure 4 The system structure block diagram of the embodiment of the present application; Figure 5 The structure block diagram of an electronic device of the embodiment of the present application. DETAILED DESCRIPTION

[0024] The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments. It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict.

[0025] The following detailed description is merely exemplary in nature and is intended to provide further detail on the present application. All the technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs unless otherwise specifically defined herein. The terminology used herein is for describing particular embodiments only and is not intended to be limiting according to the example embodiments of the present application.

[0026] Referring to Figure 1 The present application discloses a unified management and linkage control method for electric vehicle simulation sound effects, comprising: S1: obtaining a user response, determining a current global effective mode from a plurality of preset sound effect modes according to the user response; obtaining a vehicle state signal in real time, and identifying a specific interaction scene currently experienced by the vehicle according to a preset determination condition; S2: querying a scene-feedback rule set pre-associated with the sound effect mode according to the current global effective mode and the specific interaction scene, and obtaining a feedback rule; S3: uniformly controlling the sound effect system and at least one linkage device of the vehicle to execute corresponding feedback actions based on the feedback rule; and returning to obtaining the vehicle state signal in real time after execution is completed.

[0027] By establishing a globally effective sound effect mode and taking it as a single source for all subsequent feedback, the problem of different sound effects and feedback styles in different driving or interaction scenes and lack of overall sense in the prior art is fundamentally solved. No matter what state the vehicle is in, the system responds based on the same set of theme rules, ensuring the integrity of the user experience and the unified expression of the brand style. Relying on the pre-set "scene-feedback rule set" for querying and execution decouples the specific feedback logic from the core control program. This data-driven design allows new interaction scenes, adjusted sound effect content, or bound new linkage devices (such as fragrance systems) to be updated by simply updating the rule database without modifying the underlying software code. This greatly facilitates the iteration and customization of functions, and is particularly suitable for remote upgrades through OTA (Over-the-Air Technology). Based on the feedback rule, the sound effect system and linkage devices such as ambient light and seat wings are uniformly controlled, expanding the single auditory feedback into a comprehensive sensory experience with sound, light, and tactile coordination. For example, during mode switching, the theme sound effect, light color, and seat posture are triggered simultaneously, creating a strong sense of ritual and immersion for the user and significantly improving the driving pleasure and emotional connection of the electric vehicle.

[0028] In some embodiments, the plurality of preset sound effect modes comprises: A first mode associated with a first type of style basic simulation sound wave, the corresponding scene-feedback rule set defining the feedback action of the linkage device as a first set of parameters; The second mode is associated with the basic simulated sound waves of the second style, and its corresponding scene-feedback rule set defines the feedback action of the linked device as the second set of parameters. The third mode is associated with the third type of basic simulated sound waves, and its corresponding scene-feedback rule set defines the feedback action of the linked device as the third set of parameters. The basic simulated sound waves of the first, second, and third styles are different from each other, and the settings of the first, second, and third sets of parameters are also different. This ensures a consistent and immersive user experience, avoiding the problems of chaotic and piecemeal feedback styles between different functions, and creating a highly coordinated and brand-characteristic cockpit atmosphere. Since the core definition of the mode lies in flexibly configurable data (rule sets) rather than hard-coded program logic, if a "fourth mode" is added or the linkage effect of an existing mode is modified, developers do not need to rewrite the core control code; they only need to add or modify configuration entries in the rule database. This makes adding features and personalizing updates via OTA (Over-The-Air technology) extremely convenient. Finally, it provides users with clear, intuitive, and emotionally valuable personalized choices.

[0029] In some embodiments, the first set of parameter settings includes: When the accelerator pedal is pressed while the car is parked, the feedback action is to modulate and play the basic analog sound of the first style associated with it in real time, and the modulation parameters are positively correlated with the pedal depth and rate of change. When the brake pedal is pressed while parking, the feedback action is to play a mechanical confirmation sound derived from the basic simulated sound of the first style; When a mode is activated or switched, the feedback actions are as follows: play the preset opening sound, set the ambient light to red, and adjust the seat side wings to the first position.

[0030] In some embodiments, the three specific scenarios are handled differently: Scenario 1 (P gear, accelerator pedal pressed): Query and execute the Scenario 1 rule for mode X -> Real-time modulation playback of the sound associated with mode X.

[0031] Scenario 2 (P gear, brake pedal pressed): Query and execute the Scenario 2 rule of mode X -> play the brake confirmation sound effect associated with mode X.

[0032] Scenario 3 (Mode Switching / Loading): Query and execute the Scenario 3 rule of Mode X -> Simultaneously trigger multi-device function linkage of sound effects, lighting, and seat side wings.

[0033] Rule-driven unified response: The processing of each scenario follows the same logic. Scenario judgment -> query corresponding rules of current mode -> execute action defined by rules Ensure the feedback style of different scenarios in the same mode is unified Continuous monitoring loop: the system continuously monitors all scenarios, and returns to the monitoring state after any scenario is triggered, forming a complete interactive closed loop.

[0034] In some embodiments, in the second set of parameters, when the mode is activated or switched, the feedback action is to play a preset opening sound, set the atmosphere lamp to blue, and adjust the seat wing to the second gear. In the third set of parameters, when the mode is activated or switched, the feedback action is to play a preset opening sound, set the atmosphere lamp to yellow, and adjust the seat wing to the third gear.

[0035] In some embodiments, the vehicle state signals are obtained in real time, and according to a preset judgment condition, the specific interactive scenario in which the vehicle is currently located is identified; including: The gear state, accelerator pedal opening, brake pedal switch state, and sound effect mode switching instruction of the vehicle are collected in real time through the vehicle internal bus; When it is determined that the vehicle is in the parking gear and the accelerator pedal opening exceeds a first preset threshold, it is identified as a parked accelerator pedal. When it is determined that the vehicle is in the parking gear and the brake pedal switch state changes from not being pressed to being pressed, it is identified as a parked brake pedal. When the sound effect mode switching instruction or vehicle wake-up instruction is detected, it is identified as the mode being activated or switched.

[0036] In some embodiments, the linkage device includes an atmosphere lamp and a seat wing adjustment device.

[0037] In some embodiments, in the preset sound effect modes, each sound effect mode is associated with a set of basic simulated sound waves and a specific scenario-feedback rule set.

[0038] Embodiment 1 The two figures together completely demonstrate the present application: Figure 2 Demonstrate the system architecture, Figure 3 Demonstrate the specific working logic, perfectly embodying the core innovation point of "unified management of multiple scenario feedbacks through a mode maker".

[0039] As shown in the accompanying Figure 1 The "electric vehicle simulated sound effect unified management and linkage control system" of the present application is physically realized based on the existing electronic and electrical architecture of the vehicle, and its core is a software system deployed on the vehicle domain controller. Through software module definition and data flow design, the system builds a "maker" architecture with clear logic and distinct levels.

[0040] 1.1 Main functional modules 1.1.1 Mode setting module (user interaction layer): This module is presented in the form of a graphical user interface as a "sound effect setter" in the settings menu of the in-vehicle infotainment system. The interface provides four top-level options: "off", "classic", "star", and "pulse". User selection operations will generate a clear mode instruction signal.

[0041] 1.1.2 Central control module (logic processing core): This is the "brain" of the system. Its main functions include: receiving and locking the user-selected mode as the globally effective theme; continuously receiving vehicle state information; querying the pre-set linkage rules according to the current effective theme and real-time scene; and finally generating and dispatching execution instructions.

[0042] 1.1.3 Scene perception module (signal input interface): This module collects and analyzes key signals in real time through the vehicle internal communication network (such as CAN bus), including but not limited to: vehicle gear state (P / R / N / D), accelerator pedal opening and change rate, brake pedal switch state, current driving mode, and vehicle speed, etc. Its core responsibility is to convert physical signals into "scene events" recognizable by the system.

[0043] 1.1.4 Data resource module: Sound effect library: stores several sets of basic simulated sound wave audio data and their derived short prompt sound effects preset by the vehicle. Each set of sound wave data has a unique identifier.

[0044] Rule database: stores the most core "scene-feedback rule set" of the invention. This database is organized in a structured manner to ensure that each sound effect mode is associated with a complete set of rules, clearly specifying which sound effect to call, how to modulate, and which linkage device actions to trigger under different preset scenarios.

[0045] 1.1.5 Executor module (output layer): Audio output system: responsible for receiving instructions and playing processed sound effects through the vehicle's power amplifier and speakers.

[0046] Linkage executor cluster: including the full-vehicle multi-color ambient light controller and the electric seat wing controller with multi-gear adjustment function, for receiving linkage instructions and producing visual and tactile feedback.

[0047] Implementation of the "mode-scene-rule" core architecture The core innovation of the invention lies in establishing and implementing the "mode-scene-rule" three-layer logical management architecture. The key to its implementation lies in the construction of the rule database and the logical design of the central control module.

[0048] In implementation, a separate configuration file or data table entry is established for each sound effect mode (e.g. "Classic Mode"). This entry mainly contains two core fields: 2.1 Associated sound effect identifier: points to the corresponding base sound wave data in the sound effect library (e.g. "V8 engine sound sample").

[0049] 2.2 Scene-feedback rule set: This is a structured data set in the form of "key-value" pairs, defining the specific "feedback action" that the mode should perform under different "scene numbers".

[0050] For example, for "Classic Mode", its rule set will explicitly: When "Scene One" (parking with accelerator pedal pressed) occurs, the feedback action is "real-time modulation playback of its associated V8 engine sound, with modulation parameters positively correlated with pedal depth and rate of change".

[0051] When "Scene Two" (parking with brake pedal pressed) occurs, the feedback action is "play a short mechanical confirmation sound derived from the V8 engine sound".

[0052] When "Scene Three" (mode activated or switched) occurs, the feedback action is "play the iconic opening sound, set the atmosphere light to red, and adjust the seat wings to the first gear".

[0053] "Star Mode" and "Pulse Mode" are respectively associated with their corresponding science fiction sound effects, pulse sound effects, and bind different linkage rules such as blue light / 2 gear seat, yellow light / 3 gear seat, etc.

[0054] Workflow of three core interaction scenes Combined with the attached Figure 2 , the system's workflow under the three preset scenes is as follows: 3.1 Scene One: Lightly press the accelerator pedal in the parking state (emotional interaction) 3.1.1 Trigger and judgment: The vehicle is in P gear. The scene perception module detects that the accelerator pedal opening exceeds the preset sensitivity threshold (e.g. 5%), immediately sends a "Scene One Trigger" signal to the central control module, and attaches the real-time pedal depth and pedal speed data.

[0055] 3.1.2 Rule matching: The central control module confirms the current globally effective mode (e.g. "Classic Mode"), and then retrieves the feedback rules preset for "Scene One" in this mode from the rule database.

[0056] 3.1.3 Dynamic sound effect synthesis and playback: According to the rule, the system calls the base sound wave data associated with the "Classic Mode" from the sound effect library. At the same time, based on the real-time pedal parameters received, the loudness of the sound effect (proportional to the pedal depth) and the pitch change rate (proportional to the pedal pressing speed) are dynamically adjusted through the built-in digital signal processing algorithm. The processed sound effect is played through the audio system, creating a real-time interactive auditory experience like operating a large displacement engine.

[0057] 3.1.4 Technical effect: This scenario transforms the meaningless parking pedal stepping action into a vehicle "breathing" or "response" with emotional feedback and immersion, greatly enhancing the emotional connection between the driver and the vehicle and the driving pleasure, and the feedback strictly follows the style of the selected mode.

[0058] 3.2 Scenario Two: Pressing the brake pedal in the parking state (safety confirmation feedback) 3.2.1 Trigger and judgment: The vehicle is in P gear. The scene perception module detects the brake pedal switch state change (from not stepping to stepping) and sends a "Scenario Two Trigger" signal.

[0059] 3.2.2 Rule matching: The central control module queries the rules preset for "Scenario Two" in the current effective mode.

[0060] 3.2.3 Unique sound effect playback: The rule instructs the system to play a unique confirmation sound effect that is strongly associated with the mode. This sound effect is not a general prompt sound, but is designed to be consistent with the theme of the mode in terms of sound design (such as "Classic Mode" corresponding to a steady mechanical sound, "Star Mode" corresponding to a science fiction electronic sound). The sound effect is short and clear, usually within 300 milliseconds.

[0061] 3.2.4 Technical effect: This design provides a branded operation confirmation feedback. In the quiet cabin of an electric vehicle, it clearly informs the driver that "the brake command has been received and the vehicle is ready", effectively making up for the lack of traditional fuel vehicle engine vibration feedback, improving the operation confidence and safety, and strengthening the brand sound identification.

[0062] 3.3 Scenario Three: Sound effect mode switching or vehicle wake-up (multi-sensory immersive linkage) 3.3.1 Trigger and judgment: When the user switches the sound effect mode through the interface, or the vehicle starts loading the user's preference settings, the system determines that "Scenario Three" is triggered.

[0063] 3.3.2 Rule matching: The central control module queries the "Scenario Three" rules under the newly activated mode.

[0064] 3.3.3 Multi-channel coordinated execution: According to the rules, the system executes the following instruction sequence in parallel: Auditory channel: play a specially designed opening theme sound effect for this mode, establish a clear auditory cognition.

[0065] Visual channel: send instructions to the ambient light system, switch the entire vehicle light color to the theme color bound to this mode (such as classic-red, interstellar-blue, pulse-yellow), and can be accompanied by a soft brightness gradient effect.

[0066] Tactile channel: send instructions to the seat controller, adjust the wing support to the preset tightening gear of this mode, and provide the corresponding wrapping feeling.

[0067] Technical effect: this scene realizes the leap from single function switching to overall cabin experience switching. The user is surrounded by consistent sound, light, and tactile information in an instant, forming a strong theme immersion and brand exclusive ritual. This is not only the realization of function, but also the top presentation of emotional design and user experience.

[0068] System key features and advantages 4.1 Experience uniformity and consistency: all feedback sources of all scenes come from the same global active mode selected by the user. The system drives all feedback by querying the unified rule set in this mode, fundamentally ensuring the complete uniformity of user experience style on different interaction nodes, avoiding the problem of inconsistent sound effect style in traditional solutions.

[0069] 4.2 Rule flexibility and extensibility: the "scene-feedback rule set" is data-centered and decoupled from program logic. This means that by updating the rule database (such as through OTA remote upgrade), new scenes can be added, feedback content can be modified, or new linked devices can be bound without rewriting the core software. The system has strong extensibility.

[0070] 4.3 Lightweight implementation and high integration: the invention is mainly implemented by adding an intelligent "formulator" logic layer in the software layer, making full use of the existing sensors, actuators, and audio hardware resources of the vehicle, without the need to add expensive dedicated hardware, with high cost-effectiveness and engineering feasibility.

[0071] In summary, the invention builds a software-defined interaction system centered on "mode" and driven by "rules", creatively integrating the scattered sound effects and cabin functions of electric vehicles into several complete, customizable, and deeply immersive theme experience packages. It effectively solves the pain points of scattered interaction feedback and fragmented style in existing technologies, providing a practical system solution for the next generation of intelligent and personalized human-vehicle interaction.

[0072] Embodiment 2 As Figure 4As shown, based on the same inventive concept as the above embodiment, the application also provides a unified management and linkage control system for electric vehicle simulation sound effects, comprising: A response recognition unit is configured to acquire a user response, determine a current global effective mode from a plurality of preset sound effect modes according to the user response, acquire a vehicle state signal in real time, and identify a specific interaction scene in which the vehicle is currently located according to a preset determination condition; A query unit is configured to query a scene-feedback rule set pre-associated with the sound effect mode according to the current global effective mode and the specific interaction scene, and obtain a feedback rule; An execution feedback unit is configured to uniformly control a sound effect system and at least one linkage device of the vehicle to perform a corresponding feedback action based on the feedback rule, and return the vehicle state signal acquired in real time after the execution is completed.

[0073] In some embodiments, a unified management and linkage control system for electric vehicle simulation sound effects, the core innovation lies in introducing a "mode-scene-rule" three-layer management architecture: The mode layer (response recognition unit) provides a plurality of complete "sound effect experience packages" (modes) for user selection, each mode is bound to a basic sound wave, a current global effective mode is determined from a plurality of preset sound effect modes according to a user response, a vehicle state signal is acquired in real time, and a specific interaction scene in which the vehicle is currently located is identified according to a preset determination condition; The rule layer (query unit) predefines a set of "scene-feedback rules" for each mode, which clearly specifies how to play sound effects (call which sound wave, how to modulate) and trigger which linkage devices (such as ambient light color, seat posture) in a plurality of preset interaction scenes such as "parking and stepping on the accelerator", "parking and stepping on the brake", and "mode switching". A scene-feedback rule set pre-associated with the sound effect mode is queried according to the current global effective mode and the specific interaction scene, and a feedback rule is obtained; The execution layer (execution feedback unit) monitors the vehicle scene in real time, and automatically calls the corresponding rules for execution according to the mode currently selected by the user, to ensure that the feedback in all scenes conforms to the unified style of the mode. A sound effect system and at least one linkage device of the vehicle are uniformly controlled to perform a corresponding feedback action based on the feedback rule; the vehicle state signal acquired in real time is returned after the execution is completed.

[0074] Unified mode management: all scenes are based on the same current global effective mode (mode X), which is the basis for realizing experience uniformity.

[0075] Embodiment 3 As Figure 5 shown, the application also provides an electronic device 100 for implementing a unified management and linkage control method for electric vehicle simulation sound effects; The electronic device 100 comprises a memory 101, at least one processor 102, a computer program 103 stored in the memory 101 and executable on the at least one processor 102, and at least one communication bus 104.

[0076] The memory 101 can be used to store the computer program 103, and the processor 102 can realize the steps of the unified management and linkage control method of the simulated sound effect of the electric vehicle by running or executing the computer program stored in the memory 101 and calling the data stored in the memory 101.

[0077] The memory 101 can mainly comprise a program storage area and a data storage area, wherein the program storage area can store an operating system, at least one application program required by a function (such as a sound playing function, an image playing function, etc.), and the like; and the data storage area can store data (such as audio data) created according to the use of the electronic device 100. In addition, the memory 101 can comprise a non-volatile memory, such as a hard disk, a memory, a plug-in hard disk, a smart media card (SMC), a secure digital (SD) card, a flash card, at least one disk storage device, a flash memory device, or other non-volatile solid-state storage device.

[0078] The at least one processor 102 can be a central processing unit (CPU), and can also be other general-purpose processors, digital signal processors (DSPs), application specific integrated circuits (ASICs), field-programmable gate arrays (FPGAs) or other programmable logic devices, discrete gates or transistor logic devices, discrete hardware components, etc. The processor 102 can be a microprocessor or can also be any conventional processor, etc. The processor 102 is the control center of the electronic device 100, and connects all parts of the electronic device 100 through various interfaces and lines.
