Description

Technical Field

[0001] This application relates to the field of vehicle control technology, and particularly relates to a method, system, device, equipment, medium and product for controlling an electric horn of a vehicle. Background Art

[0002] As an important safety warning device of an automobile, the electric horn is mainly used to emit a sound warning during driving to alert pedestrians and other vehicles, so as to avoid potential traffic accidents. However, with the acceleration of the urbanization process and the increase in the number of vehicles, the usage frequency of the electric horn has also increased significantly, which brings the problem of noise pollution in some special environments.

[0003] In the prior art, after the driver presses the horn button, the horn switch is triggered, and then the horn switch generates a signal. Further, the microcontroller unit (MCU) in the in-vehicle infotainment system receives the signal generated by the horn switch, retrieves the pre-stored horn sound effect data from the memory, processes the retrieved horn sound effect data through a filter to obtain a sound effect signal, and then transmits the sound effect signal to a power amplifier. After amplifying the sound effect signal to a sufficient volume, the horn sound is emitted through the electric horn.

[0004] However, the above method integrates the function of the electric horn into a general system, which requires the design of hardware such as MCU, filter, power amplifier and software, makes significant changes to the existing vehicle structure, increases the complexity of the vehicle structure, and the adjustment of the horn volume needs to be achieved through complex system settings, and the adjustment process is complex. Summary of the Invention

[0005] This application provides a method, system, device, equipment, medium and product for controlling an electric horn of a vehicle, which does not require significant hardware modifications to the vehicle, reduces the implementation cost and complexity. When the vehicle enters a special environment where noise needs to be reduced, the driver only needs to turn on the corresponding switch in the IVI, and the BCM can detect the corresponding target message information. At this time, when the driver presses the electric horn switch on the steering wheel, the BCM can, based on the received target message information, not control the electric horn to work, but instead forward the target message information to the IVI, and the IVI controls the AVAS to simulate the electric horn to sound, and by providing adjustable volume control, the vehicle can meet the requirements of different application scenarios.

[0006] In a first aspect, this application provides a method for controlling an electric horn of a vehicle, which is applied to a vehicle electric horn control system; the method includes:

[0007] After the body control module (BCM) receives the instruction to honk the horn, it detects the target message information and the target working state of the electric vehicle alert sound system (AVAS). When it determines that the working state of AVAS is the on state based on the target working state, it controls the electric horn to turn off and sends the target message information to the in-vehicle infotainment system (IVI); the target message information is used to indicate the volume size of the vehicle horn.

[0008] After the IVI receives the target message information, it controls AVAS to turn on based on the target message information and emits the sound effect of the target volume.

[0009] Therefore, compared with the existing situation of making major modifications to the existing vehicle structure to achieve the adjustment of different volumes of the vehicle and the complex volume adjustment process, this application does not need to transform the hardware in the vehicle, but utilizes the control capabilities of the existing BCM and IVI to efficiently manage the sound effect output of AVAS and ensure the coordinated operation among various modules.

[0010] Furthermore, this application intelligently selects to use AVAS instead of the electric horn to sound by detecting the working state of AVAS, thereby achieving more appropriate volume control. And when high volume is not required, the electric horn can also be turned off to reduce unnecessary noise pollution, especially in quiet environments such as near schools or hospitals, reducing the interference to the surrounding environment. In this way, by reasonably allocating tasks to AVAS and the electric horn, it is ensured that in different environments, the vehicle can emit an appropriate reminder volume, neither disturbing the people nor failing to effectively warn pedestrians. Based on this intelligent and user-friendly control experience, the user experience can be greatly enhanced.

[0011] It should be noted that this application can more effectively utilize resources and avoid unnecessary energy consumption by intelligently controlling the working states of the electric horn and AVAS.

[0012] Optionally, the method further includes:

[0013] When the BCM determines that the working state of AVAS is the off state based on the target working state, it parses the target message information to obtain the first operation information, controls the electric horn to turn on based on the first operation information, and emits the horn sound.

[0014] In this way, this application flexibly switches to the traditional electric horn when AVAS is unavailable or not suitable for use, ensuring that the vehicle can emit the necessary warning sound. And in some cases, using the electric horn may be more appropriate than AVAS, for example, when a clear and direct sound effect reminder is needed or in the case of the user's special needs. Therefore, by parsing and utilizing the target message information, when AVAS is turned off, it can be ensured that the vehicle can continue to provide effective sound effect reminders and maintain the continuity of safety and functions.

[0015] Optionally, a control switch is provided in the IVI, and the control switch is used to control the working state of the AVAS; based on the target message information, the AVAS is controlled to turn on and a sound effect sound of the target volume is emitted, including:

[0016] Parse the target message information to obtain second operation information, so that the control switch controls the AVAS to turn on based on the second operation information and emits a sound effect sound of the target volume.

[0017] Therefore, by providing a control switch in the IVI, higher flexibility and controllability are provided, allowing the dynamic management of the working state of the AVAS according to specific requirements. By dynamically adjusting the volume and controlling the working state of the AVAS, interference to the environment can be reduced when high-volume prompts are not required, and in cases where warnings are needed, it can be ensured that the AVAS can emit prompt sounds in a timely and appropriate manner, improving driving safety; among them, by utilizing the control ability and parsing function of the IVI, the target message information is parsed and the second operation information is generated, making the volume control more accurate, ensuring appropriate sound effect prompts in different environments, and then realizing the efficient coordination between various modules, ensuring the accuracy and timeliness of the sound effect output, and through an intelligent control mechanism, unnecessary activation of the AVAS can also be avoided, thereby improving the overall efficiency.

[0018] Optionally, the method further includes:

[0019] Based on the IVI's response to the user's selection operation, generate the target message information of the electric horn and the AVAS.

[0020] Therefore, through the selection operation provided by the IVI, the user obtains greater control and can flexibly adjust the sound effect settings in different situations. Since different users may have different needs and preferences, by allowing users to make selections, it can better adapt to diverse needs. Then, the user can select the sound effect output of the electric horn and the AVAS according to their own preferences and needs. This personalized setting enhances the user experience and makes driving more enjoyable.

[0021] Optionally, the IVI has a display interface and a vehicle multimedia system host HU; based on the IVI's response to the user's selection operation, generating the target message information of the electric horn and the AVAS includes:

[0022] In response to the user's touch operation on the switch button and / or the select volume button on the display interface, generate a target signal;

[0023] After receiving the target signal, the HU generates the target message information of the electric horn and the AVAS based on the target signal.

[0024] It can be understood that the user operates through a touch interface. This intuitive interaction method makes the sound effect setting simple and easy to use, improving the user experience. Moreover, the user can flexibly select the sound output of the electric horn and AVAS according to personal preferences and the current environment to meet personalized needs.

[0025] Therefore, by providing a switch and volume selection function, this application gives the user greater control, allowing for quick adjustment of the sound effect settings in different situations. Furthermore, the user can adjust the sound effect settings according to the current driving environment, thereby improving safety and driving comfort. And the user can choose to reduce the volume or change the sound effect type in a specific environment to reduce interference with the surrounding environment. This shows higher flexibility and adaptability by allowing the user to participate in the settings and can quickly respond to the changing needs of the user.

[0026] Optionally, AVAS is used to collect the horn sound of the electric horn and simulate sound effect sounds of at least one volume; the sound effect sounds of at least one volume correspond to the sound effect sounds of different sound pressure level gears.

[0027] In this way, by simulating the sound effect sounds of different sound pressure level gears, AVAS can provide diverse sound effect selections, better adapting to different environments and needs, enabling the selection of appropriate warning volumes in different driving environments and reducing noise pollution to the environment.

[0028] Optionally, the electric horn is provided with a horn switch and a combination switch. The combination switch communicates with the BCM through the Controller Area Network (CAN) bus; the method further includes:

[0029] In response to the user's triggering operation on the horn switch, an electrical signal is generated;

[0030] Based on the combination switch, the electrical signal is received, and after receiving the electrical signal, the target message information is sent to the BCM based on the CAN bus.

[0031] In this way, this application communicates through the CAN bus, can quickly respond to the user's horn operation, ensuring timely emission of the prompt sound. And by using the combination switch and the CAN bus, multiple functions can be integrated, simplifying the vehicle's electronic architecture. This design allows for adjustment and optimization of vehicle functions through software updates without changing the physical hardware.

"And / or" describes the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist simultaneously, and B exists alone, where A and B can be singular or plural. The character " / " generally represents an "or" relationship between the associated objects before and after. "At least one (item)" or its similar expression below refers to any combination of these items, including any combination of single item (item) or plural items (items). For example, at least one (item) of a, b, or c can represent: a, b, c, a - b, a - c, b - c, or a - b - c, where a, b, and c can be single or multiple.

[0069] The following explains the professional terms involved in the present application.

[0070] Body Control Module (BCM): It refers to an electronic control unit in a vehicle, which is responsible for managing and controlling various electronic auxiliary systems and functions in the vehicle. These functions may include vehicle lights, windows, door locks, air conditioning systems, windshield wipers, etc. The embodiments of this application do not make specific limitations here.

[0071] Acoustic Vehicle Alert System (AVAS): It refers to an acoustic warning system for electric vehicles and hybrid vehicles, which is used to emit a synthetic sound when the vehicle is driving at a low speed to alert users and other road users of the approach of the vehicle.

[0072] In-Vehicle Infotainment (IVI): It refers to a multimedia system integrated in a vehicle, which is used to provide entertainment, information and communication functions. IVI usually includes functions such as audio and video playback, navigation, Internet connection, voice recognition, Bluetooth connection, application support, etc.

[0073] Head Unit (HU): It refers to the core component of IVI, usually installed on the dashboard. HU is the main interface for users to interact with the vehicle's multimedia functions, and is used to control audio, video, navigation and other infotainment functions. This HU is usually equipped with a touch screen, buttons and knobs for easy user operation.

[0074] Electric horn: It is a sound warning device installed on a vehicle, which is used to emit a loud sound signal to warn other road users or attract the attention of the user.

[0075] In special environments sensitive to noise such as hospitals, schools, and residential areas, the electric horns of traditional vehicles may cause noise pollution to the surrounding environment due to their fixed high volume, interfering with people's normal life and work. Due to the design limitations of traditional electric horns, drivers cannot adjust the volume according to environmental needs. Therefore, using the electric horn function in the above specific environments may not only cause people's dissatisfaction, but also lead to negative evaluations of vehicle drivers.

[0076] Therefore, in today's society where people have higher and higher requirements for environmental noise and quality of life, the electric horn that emits a fixed warning sound urgently needs to be optimized to emit a warning sound with a suitable volume according to different scenarios.

[0077] In related technologies, common methods for adjusting the volume of an electric horn include adding a variable resistor to the circuit or using electric horns with different powers. Although these methods can achieve volume adjustment to a certain extent, they have some obvious limitations and challenges. For example, it is necessary to modify the vehicle's circuit, which may involve complex circuit design and installation processes, making it difficult to achieve automated control, or it requires replacing the horn itself, involving physical replacement of hardware and resulting in high costs.

[0078] In one possible implementation, the functions of the electric horn, speaker, and AVAS can also be integrated into a total system, and the hardware, such as the MCU, filter, power amplifier, and software, can be designed. In this way, the system can, according to the user's selection instruction, activate the corresponding speaker mode and execute corresponding actions. For example, after the driver presses the horn button, the horn switch is triggered, and then the horn switch generates a signal. Further, the MCU in the in-vehicle entertainment system receives the signal generated by the horn switch, retrieves the pre-stored horn sound effect data from the memory, processes the retrieved horn sound effect data through the filter to obtain a sound effect signal, and then transmits the sound effect signal to the power amplifier. After amplifying the sound effect signal to a sufficient volume, the horn sound is emitted through the electric horn.

[0079] In another possible implementation, when the selection instruction is to activate the external speaker mode, the vehicle's power supply is turned on, and the external audio switch is turned on. At this time, the in-vehicle entertainment system is triggered and sends an audio signal. Then, after the audio signal is amplified to the corresponding volume by the in-vehicle power amplifier, it is emitted by the external integrated AVAS speaker.

[0080] Although the above two methods achieve the adjustment of the vehicle volume, the above methods involve modifications to the vehicle structure and hardware replacement, which not only increase the complexity of the vehicle structure but also may lead to a decrease in the vehicle's reliability. Moreover, the adjustment of the horn volume needs to be achieved through complex system settings, and the adjustment process is complex.

[0081] In view of the above problems, the present application provides a method for controlling a vehicle electric horn. When the driver issues a honking command, the BCM receives the command. Then, the BCM can detect target message information related to honking, including the required volume level. At the same time, the BCM checks the target working state of the AVAS. If the working state of the AVAS is determined to be the on state, the BCM will control the electric horn in the vehicle to be turned off, that is, not control the electric horn to work, so as to avoid conflicts with the sound output of the AVAS. Further, the BCM sends the target message information to the IVI. After receiving the target message information, the IVI controls the sound effect output of the AVAS according to the target message information, that is, controls the AVAS to turn on and emits corresponding sound effect sounds according to the indicated volume level. In this way, the present application does not require modification of the hardware in the vehicle. Instead, by designing a set of control logics and using the existing BCM and IVI for control, it is possible to change the previous control of the electric horn to sound by the IVI controlling the AVAS to simulate the sound of the electric horn. This can not only adjust the volume and simplify the volume adjustment process, but also save costs and reduce complexity.

[0082] Among them, by using the AVAS, the honking volume can be dynamically adjusted according to environmental needs, avoiding the problems of being too harsh in a quiet environment or insufficient volume in a noisy environment, improving driving safety, as well as the satisfaction of drivers and pedestrians. Moreover, by intelligently controlling the opening and closing of the electric horn, unnecessary high-volume horn sounds are reduced, and the noise pollution to the surrounding environment is lowered.

[0083] Optionally, the vehicle electric horn control method provided by the present application is applied to a vehicle electric horn control system. Exemplarily, Figure 1 is a schematic structural diagram of a vehicle electric horn control system provided by an embodiment of the present application. As Figure 1 shown, the vehicle electric horn control system 200 includes a BCM 201, an IVI 202, an AVAS 203, and an electric horn 204; the AVAS 203 is used to generate sound effect sounds of at least one volume level;

[0084] The vehicle electric horn control system 200 is used to execute the vehicle electric horn control method provided by the present application.

[0085] Among them, the AVAS 203 can generate sound effect sounds of different volume levels according to the environment and requirements, realizing intelligent volume adjustment, which enables the vehicle to emit appropriate reminder sounds in different environments, avoiding being overly harsh or having insufficient volume.

[0086] Optionally, the IVI 202 has a display interface and an HU; the display interface can be a display screen, and the present application embodiment does not make specific limitations on the manifestation form of the display interface.

[0087] Optionally, a control switch is provided in the IVI 202, and the control switch is used to control the working state of the AVAS 203.

[0088] Optionally, a honking switch and a combination switch are provided in the electric horn 204. The combination switch communicates with the BCM via a Controller Area Network (CAN) bus; the honking switch is usually provided on the steering wheel, and the honking switch can also be a horn switch.

[0089] The vehicle electric horn control system 200 uses existing vehicle-mounted systems (BCM and IVI) for control, without major hardware modifications to the vehicle, reducing the implementation cost and complexity. This method also improves the reliability and maintenance convenience of the vehicle. Moreover, the system 200 can dynamically adjust the volume to flexibly adapt to various driving environments. Whether it is a quiet residential area or a busy urban street, it can provide appropriate sound effect prompts. In this way, by providing adjustable volume control, the system 200 helps the vehicle meet the requirements for vehicle noise in different regions and environments.

[0090] Exemplarily, Figure 2 FIG. is a schematic diagram of an application scenario provided by an embodiment of the present application. As Figure 2 shown, this application scenario takes the driving process of a vehicle on a road as an example. This application scenario includes a vehicle 100, and the vehicle 100 includes a BCM 201, an IVI 202, an AVAS, an electric horn, and a steering wheel 21; optionally, the IVI 202 has a display screen 22, and the display screen 22 displays option buttons for controlling the opening and closing of the horn switch and three selection volume buttons for high, medium, and low.

[0091] During the driving process of the vehicle 100, if passing by a school area, at this time, if the electric horn sounds to warn pedestrians, since the corresponding sound of the electric horn is too loud, it may affect the ongoing classroom teaching or students' learning activities, and the continuous high-volume horn sound will cause noise pollution to the environment around the school.

[0092] In the above case, the driver can click the "ON" button corresponding to the horn switch on the display screen 22 and select the "LOW" button among the volume buttons. Then, the IVI 202 can send the message information of this event to the BCM 201 so that the BCM 201 records the working state of the AVAS at this time. Further, when the driver presses the horn switch on the steering wheel 21, the BCM 201 can detect the message information of this event and the working state of the AVAS. After receiving the message information of this event, the BCM 201 does not control the electric horn to work but forwards the message information of this event to the IVI 202 so that the IVI 202 controls the AVAS to work based on the message information of this event, that is, controls the AVAS to turn on and emits a sound effect with a low volume. In this way, the low-volume prompt sound can not only ensure that pedestrians notice the presence of the vehicle 100, thereby improving safety, but also effectively reduce the interference to classroom teaching and student learning.

[0093] Optionally, in some noisy environments, a high-volume sound effect can also be selected based on the above method. Then, the AVAS can emit a loud enough prompt sound to ensure that pedestrians and other road users can notice the approach of the vehicle 100 and improve driving safety. The implementation process is similar to the above embodiment and will not be elaborated here.

[0094] Optionally, when the vehicle 100 is driving normally and there is no need to adjust the horn volume of the vehicle 100, the driver can click the "OFF" button corresponding to the horn switch on the display screen 22. Then, the IVI 202 sends the corresponding message information to the BCM 201 so that the BCM 201 records the working state of the AVAS at this time. Further, when the driver presses the horn switch on the steering wheel 21, the BCM 201 can detect the message information and the working state of the AVAS. After receiving the message information, the BCM 201 controls the electric horn to work, that is, controls the electric horn to emit a horn sound based on the default volume. At this time, the AVAS is in the off state. In this way, the vehicle 100 can directly emit a sound based on the electric horn without additional volume adjustment steps, simplifying the operation of the vehicle 100.

[0095] It should be noted that the types and quantities of the display buttons on the display screen 22 in the embodiments of the present application are not specifically limited. Different types of buttons are used to indicate different functions. For example, the display screen 22 can also display option buttons for controlling the opening and closing of the AVAS and option buttons for controlling the opening and closing of the electric horn respectively.

[0096] It can be understood that the embodiments of the present application can also be applied to hospital area scenarios, residential area scenarios, and downtown area scenarios. The embodiments of the present application do not limit the specific application scenarios, and the above are only illustrative examples.

[0097] The following will use specific embodiments to elaborate in detail on the technical solution of this application and how the technical solution of this application solves the above technical problems. These several specific embodiments below can be combined with each other, and for the same or similar concepts or processes, they may not be elaborated again in some embodiments. The embodiments of this application will be described below in conjunction with the accompanying drawings.

[0098] Figure 3 It is a schematic flowchart of a vehicle electric horn control method provided by an embodiment of this application. As Figure 3 shown, this vehicle electric horn control method is applied to a vehicle electric horn control system; this vehicle electric horn control method includes the following steps:

[0099] S301. After the BCM receives a honking instruction, it detects the target message information and the target working state of the AVAS. When it is determined based on the target working state that the working state of the AVAS is the on state, it controls the electric horn to turn off and sends the target message information to the IVI; the target message information is used to indicate the volume size of the vehicle's honking.

[0100] In an embodiment of this application, the BCM receives a honking instruction from the driver. This honking instruction can be generated by pressing the horn button, through a voice instruction, or other control interfaces. This application does not make specific limitations on this.

[0101] Exemplarily, the BCM detects the target message information related to honking. This target message information includes the volume size of the honking required by the vehicle. At the same time, the BCM checks the target working state of the AVAS. Then, based on the detected target working state, the BCM determines whether the AVAS should be turned on. If the working state of the AVAS is determined to be the on state, it means that the AVAS will be used to emit a prompt sound. Further, the BCM sends the target message information to the IVI so that the IVI can correctly control the sound effect output of the AVAS.

[0102] Among them, when the AVAS is turned on, the BCM will control the electric horn to turn off. This is to avoid the simultaneous sounding of the electric horn and the AVAS, resulting in overlapping or conflicting sounds.

[0103] It can be understood that by controlling the opening and closing of the electric horn, unnecessary high-volume horn sounds can be effectively reduced, thereby reducing the noise pollution to the surrounding environment, especially in quiet areas such as hospitals, schools, and residential areas.

[0104] S302. After the IVI receives the target message information, it controls the AVAS to turn on based on the target message information and emits a sound effect with the target volume.

[0105] In the embodiments of the present application, the sound effect sound of the target volume is the volume adjusted according to environmental and safety requirements to ensure appropriate warning effects in different environments. It can not only warn pedestrians but also avoid excessive noise interference. Especially in a quiet environment, the embodiments of the present application do not specifically limit the size of the target volume, which can be selected based on application scenario requirements.

[0106] Optionally, the target message information may be Controller Area Network (CAN) message information. The embodiments of the present application do not specifically limit the type of message information. For example, the target message information may also be message information indicating the operation of the horn, message information of the horn switch, etc.

[0107] Exemplarily, Figure 4 FIG. is a schematic flowchart of the operation of an AVAS provided by an embodiment of the present application. As Figure 4 shown, when the driver clicks the "on" button of the horn switch in the HU, the HU sends the CAN message information (horn-on message information) of this event to the BCM, and the BCM records the target working state of the AVAS at this time. When the driver presses the horn switch on the steering wheel, an electrical signal can be generated. Then, after the combination switch receives the electrical signal, it can send the CAN message information of the horn operation to the CAN bus through the CAN bus, so that the BCM can receive the CAN message information based on the CAN bus. After the BCM receives the CAN message information, it does not control the electric horn to work but forwards the CAN message information to the HU, so that the HU can control the AVAS to work after receiving the CAN message information (horn-operation message information), that is, emit the sound effect sound of the target volume.

[0108] Among them, the horn-on message information is used to indicate that the working state of the AVAS is the on state, and the horn-operation message information is used to indicate that the AVAS is turned on and emits the sound effect sound of the target volume. The horn-on message information, the horn-operation message information, and the CAN message information are all collectively referred to as the target message information.

[0109] It can be understood that the method for using or operating to control the vehicle's electric horn to sound is very simple. When the vehicle enters a special environment where noise needs to be reduced, the driver only needs to turn on the corresponding switch in the IVI, and the BCM can detect the corresponding target message information. At this time, when the driver presses the electric horn switch on the steering wheel, the BCM can, based on the received target message information, not control the electric horn to work, but instead forward the target message information to the IVI, and the IVI controls the AVAS to simulate the sound of the electric horn.

[0110] Therefore, compared with the existing method of achieving volume adjustment for vehicles, which requires significant modification to the existing vehicle structure and has a complex volume adjustment process, this application does not need to transform the hardware in the vehicle. Instead, it utilizes the control capabilities of the existing BCM and IVI to efficiently manage the sound output of the AVAS and ensure the coordinated operation of each module.

[0111] Furthermore, this application intelligently selects to use the AVAS instead of the electric horn to produce sound by detecting the working state of the AVAS, thereby achieving more appropriate volume control. And when high volume is not required, the electric horn can be turned off to reduce unnecessary noise pollution, especially near quiet environments such as schools or hospitals, reducing interference to the surrounding environment. In this way, by reasonably allocating tasks to the AVAS and the electric horn, it is ensured that in different environments, the vehicle can emit an appropriate reminder volume, neither disturbing the people nor effectively warning pedestrians. Based on this intelligent and user-friendly control experience, the user experience can be greatly enhanced.

[0112] It should be noted that this application can more effectively utilize resources and avoid unnecessary energy consumption by intelligently controlling the working states of the electric horn and the AVAS.

[0113] Optionally, the method further includes:

[0114] When the BCM determines that the working state of the AVAS is the off state based on the target working state, parse the target message information to obtain the first operation information, and control the electric horn to turn on based on the first operation information and emit a horn sound.

[0115] In this step, if the BCM determines that the working state of the AVAS is the off state, this means that the AVAS will not be used for the current sound output. At this time, the BCM can parse the target message information to extract the first operation information, which may include specific volume settings or other relevant instructions for controlling the electric horn operation. The embodiments of this application do not specifically limit the content of the first operation information.

[0116] Furthermore, based on the parsed first operation information, the BCM controls the electric horn to turn on so that the electric horn emits a corresponding horn sound according to the first operation information. The horn sound is usually the default volume or the volume adjusted according to the target message information. The embodiments of this application do not specifically limit this.

[0117] Exemplarily, Figure 5 is a schematic flow diagram of the operation of an electric horn provided by an embodiment of this application, as Figure 5As shown, when the driver presses the horn switch on the steering wheel, the horn switch is in a closed state, thus forming a complete circuit path for controlling the horn to sound. This circuit path can generate an electrical signal. Then, after the combination switch receives this electrical signal, the combination switch sends CAN message information to the CAN bus through the CAN bus. As another node, the BCM can monitor the CAN bus messages. Therefore, after the BCM receives the CAN message information based on the CAN bus, it will parse the CAN message information to obtain the first operation information.

[0118] Among them, the CAN message information sent by the combination switch can include a message identifier and a data part. The message identifier is used to indicate that the message source is the combination switch. The data part can contain specific operations. For example, when the horn button is pressed, it is "1", and when it is released, it is "0". The embodiments of the present application do not specifically limit the content of the CAN message information, and it can also include information indicating the working state of the electric horn.

[0119] It should be noted that after the horn switch is in a closed state, the generated closed signal will be transmitted to the combination switch in the form of an electrical signal through a wire. There are corresponding circuits and contacts inside the combination switch. The embodiments of the present application do not specifically limit the internal structure of the combination switch. The above is only an example for illustration.

[0120] In this way, in the case where AVAS is unavailable or not suitable for use, the present application flexibly switches to a traditional electric horn to ensure that the vehicle can emit necessary warning sounds. Moreover, in some cases, using an electric horn may be more appropriate than AVAS. For example, when a clear and direct sound effect prompt is required, or in the case of special user needs. Therefore, by parsing and utilizing the target message information, in the case where AVAS is turned off, it can be ensured that the vehicle can continue to provide effective sound effect prompts and maintain the continuity of safety and functions.

[0121] Optionally, a control switch is provided in the IVI, and the control switch is used to control the working state of AVAS; controlling AVAS to turn on and emit a sound effect sound with a target volume based on the target message information includes:

[0122] Parsing the target message information to obtain second operation information, so that the control switch controls AVAS to turn on based on the second operation information and emits a sound effect sound with a target volume.

[0123] In the present application, a control switch is provided in the IVI to manage the working state of AVAS. In this way, the BCM can adjust the control method of the electric horn according to the state of the control switch. For example, when the control switch is turned on, the BCM no longer controls the electric horn to sound and instead controls AVAS to simulate the electric horn to sound.

[0124] Exemplarily, after receiving the target message information from the BCM, the IVI parses the target message information to extract the second operation information, which specifically indicates how to adjust the working state and volume output of the AVAS. Further, based on the parsed second operation information, the control switch determines whether to turn on the AVAS. If the second operation information indicates that the AVAS needs to be turned on, the control switch will activate the AVAS to make it emit the sound effect of the target volume.

[0125] Therefore, by setting the control switch in the IVI, higher flexibility and controllability are provided, allowing the dynamic management of the working state of the AVAS according to specific requirements. By dynamically adjusting the volume and controlling the working state of the AVAS, the interference to the environment can be reduced when high-volume prompts are not required, and in case of warnings, it can be ensured that the AVAS can emit prompt sounds in a timely and appropriate manner, improving driving safety; among them, by utilizing the control ability and parsing function of the IVI, the target message information is parsed and the second operation information is generated, making the volume control more accurate, ensuring appropriate sound effect prompts in different environments, thereby achieving efficient coordination among various modules, ensuring the accuracy and timeliness of sound effect output, and through an intelligent control mechanism, unnecessary activation of the AVAS can also be avoided, thus improving the overall efficiency.

[0126] Optionally, the method further includes:

[0127] Generating the target message information of the electric horn and the AVAS based on the IVI's response to the user's selection operation.

[0128] In the embodiments of the present application, the user's selection operation may include selecting different sound effect modes, volume levels, or enabling / disabling specific functions, such as enabling / disabling the AVAS or the electric horn. The embodiments of the present application do not specifically limit the functions corresponding to the selection operation.

[0129] Exemplarily, the user performs a selection operation through the display interface of the IVI to generate the corresponding target message information, and then the generated target message information is transmitted to the BCM to adjust the working states of the electric horn and the AVAS according to the user's selection. The target message information may include the operating states, volume sizes, sound effect types, etc. of the electric horn or the AVAS. The embodiments of the present application do not specifically limit this, and the operating state includes on or off.

[0130] Optionally, receive the user's voice command, perform semantic recognition on the voice command to determine the user's operation request, and based on the operation request, determine the target working states of the electric horn and the AVAS, and then generate the target message information of the electric horn and the AVAS.

[0131] It is understandable that users can adjust the sound settings according to the current driving environment, such as cities, villages, school areas, etc., so as to improve safety and driving comfort. For example, they can choose to reduce the volume or change the sound type in a specific environment to reduce interference with the surrounding environment.

[0132] Therefore, through the selection operations provided by the IVI, users gain greater control and can flexibly adjust the sound settings in different situations. Since different users may have different needs and preferences, allowing users to make selections can better adapt to diverse requirements. Furthermore, users can choose the sound outputs of the electric horn and AVAS according to their preferences and needs. This personalized setting enhances the user experience and makes driving more enjoyable.

[0133] Optionally, the IVI has a display interface and an in-vehicle multimedia system host HU; based on the IVI's response to the user's selection operation, target message information for the electric horn and AVAS is generated, including:

[0134] In response to the user's touch operation on the switch button and / or the volume selection button on the display interface, a target signal is generated;

[0135] After receiving the target signal, the HU generates target message information for the electric horn and AVAS based on the target signal.

[0136] It should be noted that the types and quantities of the switch button and the volume selection button are not specifically limited in the embodiments of the present application. For example, the switch button can be a button indicating the opening or closing of the AVAS, or a button indicating the opening or closing of the electric horn. The number of the volume selection buttons is 5, corresponding to the sound effects of 5 sound pressure level gears respectively, such as level 1, level 2, level 3, level 4, and level 5, corresponding to the electric horn volumes of 1 / 5, 3 / 5, 5 / 3, 7 / 3 respectively.

[0137] Exemplarily, the user interacts through the display interface of the IVI. When the user performs a touch operation on the display interface, such as clicking the switch button or adjusting the volume button, the IVI generates a corresponding target signal. Further, the HU is responsible for processing these target signals and converting them into specific control instructions, that is, the HU generates target message information for the electric horn and AVAS. The target message information contains specific sound settings, such as the volume size and the enabled state. Further, the HU transmits the generated target message information to the BCM so that the BCM can detect the target message information.

[0138] It is understandable that users operate through the touch interface. This intuitive interaction method makes the sound setting simple and easy to use, enhancing the user experience. Moreover, users can flexibly choose the sound outputs of the electric horn and AVAS according to their personal preferences and the current environment to meet personalized needs.

[0139] Therefore, by providing a switch and a volume selection function, the present application gives users greater control, allowing them to quickly adjust the sound settings in different scenarios. Furthermore, users can adjust the sound settings according to the current driving environment, thereby improving safety and driving comfort. Additionally, users can choose to reduce the volume or change the sound type in a specific environment to reduce interference with the surrounding environment. This shows higher flexibility and adaptability by allowing users to participate in the settings and can quickly respond to the changing needs of users.

[0140] Optionally, the AVAS is used to collect the horn sound of the electric horn and simulate the sound effects of at least one volume; the sound effects of at least one volume correspond to the sound effects of different sound pressure level gears.

[0141] Among them, the sound effects generated by the AVAS correspond to different sound pressure level gears, which means that the AVAS can provide sound effects of multiple volume levels according to environmental requirements or user preferences.

[0142] In the present application, the working sound of the electric horn can be collected in advance as a sound source, and the AVAS simulates the sound of the electric horn and calibrates its sound pressure level. Multiple sound pressure level gears can be calibrated, such as the sound effects of the sound pressure level gears corresponding to 1 / 3, 1 / 2, and 2 / 3 of the electric horn volume. The present application embodiment does not specifically limit the number of sound pressure level gears that can be calibrated.

[0143] Optionally, the AVAS can collect the actual horn sound emitted by the electric horn, which can be achieved through a built-in microphone or other sound collection devices. The present application embodiment does not specifically limit this.

[0144] In this way, by simulating the sound effects of different sound pressure level gears, the AVAS can provide diverse sound effect selections, better adapt to different environments and needs, and enable the selection of appropriate warning volumes in different driving environments, reducing noise pollution to the environment.

[0145] Optionally, the electric horn is provided with a horn switch and a combination switch. The combination switch communicates with the BCM through the Controller Area Network (CAN) bus; the method further includes:

[0146] Generating an electrical signal in response to a triggering operation of the user on the horn switch;

[0147] Receiving the electrical signal based on the combination switch, and after receiving the electrical signal, sending the target message information to the BCM based on the CAN bus.

[0148] Among them, the CAN bus is an efficient in-vehicle communication network that allows for fast and reliable information exchange between different modules. Since the CAN bus provides a reliable communication method, it can reduce errors and interference in signal transmission and improve the stability of signal transmission.

[0149] Exemplarily, as Figure 4 shown, the user triggers the electric horn by pressing or activating the horn switch. After being triggered, the horn switch can generate an electrical signal, that is, the closed signal corresponding to the horn switch, and then transmit the generated electrical signal to the combination switch. Once the combination switch receives the electrical signal, it sends the target message information to the BCM via the CAN bus. After receiving the target message information, the BCM processes the target message information to determine how to control the electric horn and the AVAS.

[0150] Among them, the processing process includes: when the control switch is in the on state, the BCM forwards the target message information to the IVI so that the IVI can parse the target message information to determine that the electric horn is in the off state and the AVAS is in the on state; when the control switch is in the off state, the BCM parses the target message information to determine that the electric horn is in the on state and the AVAS is in the off state.

[0151] In this way, the present application can communicate via the CAN bus, quickly respond to the user's horn operation, ensure that the prompt sound is emitted in a timely manner, and by using the combination switch and the CAN bus, multiple functions can be integrated, simplifying the vehicle's electronic architecture. This design allows for adjusting and optimizing vehicle functions through software updates without changing the physical hardware.

[0152] Exemplarily, Figure 6 is a schematic flow diagram of another vehicle electric horn control method provided by an embodiment of the present application. As Figure 6 shown, this vehicle electric horn control method is applied to the body control module BCM; this vehicle electric horn control method includes the following steps:

[0153] S601. After receiving the horn instruction, detect the target message information and the target working state of the electric vehicle warning sound system AVAS.

[0154] S602. When it is determined based on the target working state that the working state of the AVAS is the on state, control the electric horn to turn off, and send the target message information to the in-vehicle infotainment system IVI so that after receiving the target message information, the IVI controls the electric vehicle warning sound system AVAS to turn on based on the target message information and emits a sound effect with the target volume; the target message information is used to indicate the volume size of the vehicle horn.

[0155] It should be noted that the specific implementation principle, process explanation, and achieved effects of S601 - S602 are similar to those of S301 - S302 described above.

[0161] S702: Control the electric vehicle alert sound system (AVAS) to turn on and emit a sound effect of the target volume based on the target message information; when the AVAS is in the on state, the electric horn is in the off state.

[0162] It should be noted that the specific implementation principle, process explanation, and achieved effects of S701 - S702 are similar to those of S301 - S302 described above. For the similar parts, reference can be made to the description of the above embodiments, and details will not be repeated here.

[0164] Parse the target message information to obtain second operation information, so that the control switch controls the AVAS to turn on and emit a sound effect of the target volume based on the second operation information.

[0165] Optionally, the method further includes:

[0169] After receiving the target signal, the HU generates target message information of the electric horn and the AVAS based on the target signal.
