Description

Technical Field

[0001] This application relates to the fields of automotive braking systems and intelligent vehicle technology, and in particular to a method, vehicle, device and medium for sharing external speakers across vehicle domains. Background Technology

[0002] Currently, the automotive electronics field mainly includes two types of automotive sound component systems: AVAS (Acoustic Vehicle Alert System, low-speed pedestrian warning system for pure electric vehicles) and car horns.

[0003] Among them, AVAS is a device that emits sounds outside the vehicle to remind pedestrians when a pure electric vehicle is traveling at low speed. It is currently widely used in some new energy vehicles and mainly integrates a sound source control module and a sound-emitting unit. The car horn is a device that serves as a traffic warning to pedestrians and other vehicles around the vehicle while it is in motion. It is a traditional driving safety component.

[0004] However, AVAS and car horns are two mature technologies and independent systems belonging to different technical domains of vehicles. Their regulations and functional safety requirements are also different, making it difficult to achieve cross-domain sharing of sound-producing devices, which greatly affects the user experience and urgently needs to be solved.

[0005] With the advent of high-pressure stage loudspeakers, they can achieve sound pressure levels that meet regulatory and functional safety requirements, previously only achievable with snail-shaped external horns, thus providing the possibility of sharing sound-generating devices across different domains.

[0033] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0034] The following description, with reference to the accompanying drawings, describes a method, vehicle, device, and medium for cross-domain sharing of external speakers in vehicles according to embodiments of this application. Addressing the problems mentioned in the background art, this application provides a method for cross-domain sharing of external speakers in vehicles. In this method, the actual vehicle speed and status information are collected; a chassis-domain horn sound source signal and / or at least one cabin-domain interactive sound source signal are generated based on the actual vehicle speed and status information. The at least one cabin-domain interactive sound source signal includes at least one of a low-speed pedestrian warning system sound source signal, an external media interactive sound source signal, and an in-vehicle sound source signal; based on the chassis-domain horn sound source signal and / or at least one cabin-domain interactive sound source signal, and in conjunction with a preset sound source management strategy, the target external speaker replaces the external snail horn to perform the corresponding sound source playback operation in the chassis domain and / or cabin domain. This application effectively reduces redundant vehicle parts, lowers overall vehicle costs, and improves the user experience by integrating low-speed pedestrian warning functions, interactive functions, and external speaker functions to share external speakers for sound emission. This solves the problem that existing vehicles have different technical domains, regulations, and functional safety requirements for sound-generating devices, making it difficult to achieve cross-domain sharing of sound-generating devices and greatly affecting the user experience.

[0035] Specifically, Figure 1 This is a flowchart illustrating a method for sharing vehicle exterior speakers across different domains, as provided in an embodiment of this application.

[0036] like Figure 1 As shown, the method for sharing exterior speakers across different vehicle domains includes the following steps:

[0037] In step S101, the actual speed and status information of the current vehicle are collected.

[0038] In step S102, a chassis domain horn sound source signal and / or at least one cabin domain interactive sound source signal are generated based on the actual vehicle speed and status information. The at least one cabin domain interactive sound source signal includes at least one of the following: a low-speed pedestrian warning system sound source signal, an external media interactive sound source signal, and an in-vehicle sound source signal.

[0039] The embodiments of this application first acquire vehicle speed information and vehicle status information in real time through devices such as vehicle speed sensors, such as vehicle driving status and power-on status. Then, based on the collected vehicle speed information and status information, and combined with the functional safety requirements of vehicle driving and traffic regulations, the system generates chassis domain horn sound source signals or cabin domain interactive sound source signals, or generates both chassis domain horn sound source signals and cabin domain interactive sound source signals simultaneously.

[0040] It should be noted that, in the embodiments of this application, the cockpit domain interactive audio source signals mainly include low-speed pedestrian warning system audio source signals, external media interactive audio source signals, and in-vehicle audio source signals. In actual implementation, those skilled in the art can also generate other types of cockpit domain interactive audio source signals according to the actual situation, which will not be elaborated here.

[0041] Therefore, the embodiments of this application utilize the vehicle's speed and status information, and, while meeting the safety requirements and legal regulations of the vehicle's current driving environment, quickly generate chassis domain horn sound source signals or cabin domain interactive sound source signals, so as to provide reliable technical support for executing subsequent external speaker sound source playback operations based on the corresponding signals.

[0042] Optionally, in one embodiment of this application, generating a chassis domain horn sound source signal and / or at least one cabin domain interactive sound source signal based on actual vehicle speed and status information includes: determining whether the current vehicle is in a driving state or a stationary state based on the status information; and generating a low-speed pedestrian warning system sound source signal when the current vehicle is in a driving state and the actual vehicle speed is not greater than a preset low-speed driving speed threshold.

[0043] It should be noted that the cockpit host in this embodiment integrates the AVAS audio source and algorithm. In actual execution, after obtaining the vehicle's status information and speed information through the internal configuration of the cockpit domain control host, the embodiment of this application can analyze and judge the status information, and generate a low-speed pedestrian warning system audio source signal when the vehicle is in a driving state and the vehicle speed meets the preset requirements.

[0044] For example, if the vehicle is in motion, the vehicle's speed information is obtained. When the vehicle speed is less than or equal to a preset speed threshold (such as 20 km / h), it can be determined that the current vehicle is traveling at low speed. The software algorithm is then processed in conjunction with the actual requirements of low-speed pedestrian warning, and a low-speed pedestrian warning system sound source signal of the corresponding frequency is emitted based on the processed result to warn pedestrians at low speed.

[0045] Therefore, the embodiments of this application can generate a low-speed pedestrian warning system sound source signal by analyzing vehicle speed, effectively ensuring safe driving of vehicles at low speeds.

[0046] Optionally, in one embodiment of this application, generating a chassis domain horn sound source signal and / or at least one cabin domain interactive sound source signal based on actual vehicle speed and status information further includes: determining whether the current vehicle is in an unlocked and powered-on state based on status information; and generating an external media interactive sound source signal when the vehicle is in an unlocked and powered-on state.

[0047] As one possible approach, embodiments of this application can also associate the vehicle's external speakers with the car key through the host system and determine whether the vehicle is currently powered on, so as to generate an external media interactive audio source signal when the user unlocks the vehicle and controls the vehicle to power on.

[0048] Therefore, the embodiments of this application can generate external media interactive audio source signals when the vehicle is powered on, thereby using the host system to drive the external speakers to play welcome music, which greatly improves the vehicle's intelligence and humanization level.

[0049] In step S103, based on the chassis domain horn sound source signal and / or at least one cabin domain interactive sound source signal, and in conjunction with a preset sound source management strategy, the target external speaker replaces the external snail horn to perform the corresponding sound source playback operation in the chassis domain and / or cabin domain.

[0050] The hardware involved in the embodiments of this application mainly includes a cockpit domain control host and external speakers, external microphones, steering wheel buttons, etc. After acquiring the chassis domain horn sound source signal and the cockpit domain interactive sound source signal, the embodiments of this application can further utilize the chassis domain horn sound source signal and the cockpit domain interactive sound source signal, and through the corresponding sound source management strategy, control the external speakers to replace the external snail horn to perform the corresponding sound source playback operations in the chassis domain and cockpit domain, so as to realize the joint control of the external high-voltage stage speakers by the intelligent cockpit domain host and the chassis domain steering wheel buttons through cross-domain fusion control logic, so as to share the sound-generating device.

[0051] Therefore, the embodiments of this application integrate the intelligent cockpit domain and the chassis domain to utilize the in-vehicle host to control the latest high sound pressure level external speaker devices, integrate the low-speed pedestrian warning and interactive functions of the external speakers with the driving safety external speaker functions, share the sound output of the external speakers, reduce redundant parts and vehicle costs, reduce vehicle weight, and greatly reduce system complexity.

[0052] Optionally, in one embodiment of this application, the audio source management strategy includes: when a low-speed pedestrian warning system audio source signal is received, and simultaneously an external media interaction audio source signal, an in-vehicle audio source signal, or a chassis domain horn audio source signal is received, controlling the target external speaker to perform audio source mixing playback; when a chassis domain horn audio source signal is received, and simultaneously an external media interaction audio source signal is received, controlling the target external speaker to perform cabin domain mute processing; when an in-vehicle audio source signal is received, and simultaneously an external media interaction audio source signal or a chassis domain horn audio source signal is received, controlling the target external speaker to perform audio source mixing playback.

[0053] It should be noted that, in the embodiments of this application, the intelligent cockpit domain controller host is connected to the external speakers to realize the functions of traditional AVAS and voice interaction; the steering wheel buttons and hard wires are connected to the external speakers to realize the function of external speakers.

[0054] In actual implementation, based on the above hardware connection method and the chassis domain horn sound source signal and cockpit domain interactive sound source signal, the embodiments of this application need to set up a reasonable and scientific sound source management strategy, as shown in Table 1:

[0055] Table 1

[0056]

[0057] Therefore, embodiments of this application can perform audio source playback operations based on chassis domain horn sound source signals and cockpit domain interactive sound source signals, such as... Figure 2 As shown, the specific audio source management strategy of this application embodiment is as follows:

[0058] 1. When a low-speed pedestrian warning system audio signal is received, and at the same time an external media interaction audio signal, an in-vehicle audio signal, or a chassis domain horn signal (such as pressing the steering wheel external horn) is received, audio source management is required to control the target external speaker to play audio source mixing, that is, the external speaker emits external horn sound, the host receives the external horn signal from the steering wheel button, and the external sound in the cabin domain is muted;

[0059] 2. When a chassis-domain horn sound source signal is received (such as when the steering wheel buttons control the external horn to work), and an external media interaction sound source signal is also received (such as in-vehicle media interaction, warnings, etc. controlled by the host), sound source management is required to control the target external speaker to perform cabin-domain mute processing. That is, when the steering wheel external horn is pressed, the external speaker emits an external horn sound, and when the host receives the steering wheel button external horn signal, the cabin-domain external sound is muted.

[0060] 3. When an in-vehicle audio source signal is received, and an external media interactive audio source signal or a chassis domain horn audio source signal is received simultaneously, the embodiments of this application can control the target external speaker to perform audio source mixing playback.

[0061] It is understood that, based on the above-mentioned audio source management strategy, the embodiments of this application can enable the sharing of external speakers and audio source playback operations in various scenarios, including chassis domain horn audio source signals and cabin domain interactive audio source signals.

[0062] For example, embodiments of this application can set the option for external speakers on the host display interface, so that the music of the host system can be played through the external speakers, thereby achieving the effect of playing music through external speakers when camping; in addition, when parked, the car owner can use the microphone system inside the car and the external speakers to make announcements from inside the car to outside, which can be used for the sales scenarios of a street vendor.

[0063] Therefore, the embodiments of this application, by setting a scientific and reasonable audio source management strategy, effectively ensure the quality and reliability of vehicle audio source playback, greatly enhance the diversity of scenarios for sharing external speakers, and improve the market competitiveness of this function.

[0064] Optionally, in one embodiment of this application, based on a chassis domain horn sound source signal and / or at least one cabin domain interactive sound source signal, and in conjunction with a preset sound source management strategy, the target vehicle external speaker is controlled to perform corresponding sound source playback operations in the chassis domain and / or cabin domain, including: when the current vehicle generates at least one cabin domain interactive sound source signal, performing a signal amplification operation on the at least one cabin domain interactive sound source signal through a preset power amplifier to generate a sound source amplification signal corresponding to the at least one cabin domain interactive sound source signal; and controlling the target vehicle external speaker to perform sound source playback operations according to the sound source amplification signal and the sound source management strategy.

[0065] It should be noted that, in the embodiments of this application, when the steering wheel in the chassis domain emits an external horn sound signal (i.e., a chassis domain horn sound source signal), the signal voltage of the chassis domain horn sound source signal is returned to the host control circuit. Furthermore, the embodiments of this application add an anti-backflow device to the host amplifier side, such as... Figure 3 As shown, this is to prevent the power signal from the external speaker from flowing back into the power amplifier.

[0066] Furthermore, in the embodiments of this application, when generating the cockpit domain interactive audio source signal, the cockpit domain interactive audio source signal is amplified by using a power amplifier integrated inside the host to generate an audio source amplification signal corresponding to the cockpit domain interactive audio source signal, which drives the external speakers to emit sound of the corresponding frequency, so as to control the external speakers to perform audio source playback operation according to the audio source amplification signal and the audio source management strategy.

[0067] Understandably, since external horns are a legal requirement for automobiles, external speakers fulfill their function by increasing the sound pressure level of the entire module. Therefore, whether the vehicle is moving or stationary, pressing the steering wheel switch sends a chassis-domain horn signal to the external speakers, which then function as external horns. The sound source and volume are calibrated to meet the horn's sound pressure level regulations and other requirements. Furthermore, the main unit hardware incorporates a design redundancy strategy to ensure that, in extreme circumstances, the external speakers can still function normally, replacing the traditional external horn.

[0068] Optionally, in one embodiment of this application, the method further includes: generating a fault diagnosis request for the target vehicle external speaker every preset diagnostic cycle, and sending the fault diagnosis request to a preset vehicle controller, so that the vehicle controller generates a fault detection signal when receiving the fault diagnosis request; acquiring electrical signal data of the target vehicle external speaker based on the fault detection signal, and determining whether the current vehicle meets preset fault conditions based on the electrical signal, and determining the fault type and fault level of the target vehicle external speaker if the fault conditions are met; generating a fault report for the target vehicle external speaker based on the fault type and fault level, and simultaneously acquiring the actual location of the current vehicle; searching for the nearest vehicle repair shop or vehicle 4S store based on the actual location, fault type and fault level, generating a navigation route for the current vehicle to the vehicle repair shop or vehicle 4S store, and sending the fault report and navigation route to the vehicle display screen and / or the target terminal device.

[0069] In actual implementation, embodiments of this application may also generate a fault diagnosis request for the external speaker at each certain diagnostic cycle (e.g., 1 minute), and send the request to the vehicle controller so that the vehicle controller can generate a fault detection signal to obtain the electrical signal data of the external speaker.

[0070] Furthermore, embodiments of this application determine whether there is a fault in the external speaker based on electrical signal data, such as unstable volume, excessive noise, or no sound, and determine the type and severity of the external speaker fault to obtain a fault level. A fault report is then generated based on the type and level of the external speaker fault. Embodiments of this application can also obtain the vehicle's current location through a GPS system to search for all vehicle repair shops or 4S stores in the vicinity (within a 2km radius of the current vehicle) based on the vehicle's current location, fault type, and fault level. The nearest vehicle repair shop or 4S store to the current vehicle is then determined, and the vehicle navigation system is controlled to automatically generate a navigation route to the nearest vehicle repair shop or 4S store. The external speaker fault report and navigation route are then sent to the in-vehicle display screen. If the user is not in the vehicle, the fault report and navigation route can also be sent to a preset terminal device, such as the user's mobile phone, to remind the user.

[0071] Therefore, the embodiments of this application perform fault detection on the external speakers of the vehicle and generate corresponding fault reports, so that the vehicle owner can understand the fault status of the external speakers in a timely manner and carry out corresponding repairs, which greatly improves the intelligence level and reliability of the vehicle.

[0072] Optionally, in one embodiment of this application, while determining whether the current vehicle meets preset fault conditions based on electrical signals, and determining the fault type and fault level of the target vehicle external speaker if the fault conditions are met, the method further includes: acquiring images of the current vehicle's external environment and inputting the images into a pre-trained pedestrian detection model to output pedestrian detection data corresponding to the external environment images; determining whether the pedestrian detection data meets preset driving safety conditions, and generating a vehicle announcement mode activation request signal if the pedestrian detection data does not meet the preset driving safety conditions, so as to activate the vehicle announcement mode of the current vehicle according to the vehicle announcement mode activation request signal; and enabling the target user to announce and remind at least one pedestrian in the current vehicle's environment through the vehicle announcement mode.

[0073] Furthermore, when the vehicle's external speakers malfunction, embodiments of this application can utilize visual sensors such as onboard cameras to acquire images of the vehicle's external environment. These images are then processed using mature pedestrian detection models such as YOLO to extract features. These features are then classified and regressed to output pedestrian detection data corresponding to the external environment images.

[0074] Furthermore, embodiments of this application can analyze pedestrian detection data to determine whether the pedestrian detection data meets preset driving safety conditions, such as whether the pedestrian density in the current vehicle's driving environment is greater than a preset threshold, or whether there are obstacles or pedestrians in the vehicle's driving direction. If the pedestrian detection data does not meet the preset driving safety conditions, that is, if the pedestrian density in the current vehicle's driving environment is high, or if there are obstacles or pedestrians in the vehicle's driving direction, a vehicle announcement mode activation request signal can be generated to activate the current vehicle's announcement mode, so that the user can announce and remind pedestrians in the current vehicle's environment in the vehicle announcement mode.

[0075] Therefore, in the embodiments of this application, when the external speaker malfunctions and the preset driving safety conditions are not met, the vehicle's announcement mode is activated to announce and remind pedestrians, thereby greatly ensuring the safety of the vehicle and pedestrians and improving the user's driving experience.

[0076] The method for sharing vehicle external speakers across domains according to the embodiments of this application involves collecting the actual vehicle speed and status information; generating a chassis domain horn sound source signal and / or at least one cabin domain interactive sound source signal based on the actual vehicle speed and status information, wherein the at least one cabin domain interactive sound source signal includes at least one of a low-speed pedestrian warning system sound source signal, an external media interactive sound source signal, and an in-vehicle sound source signal; based on the chassis domain horn sound source signal and / or at least one cabin domain interactive sound source signal, and in conjunction with a preset sound source management strategy, the target external speaker replaces the external snail horn to perform the corresponding sound source playback operation in the chassis domain and / or cabin domain. This application effectively reduces redundant vehicle parts, lowers the overall vehicle cost, and improves the user experience by integrating low-speed pedestrian warning function, interactive function, and external speaker function to share the external speaker for sound emission.

[0077] Secondly, an apparatus for sharing vehicle exterior speakers across different areas according to an embodiment of this application will be described with reference to the accompanying drawings.

[0084] The request module is used to generate a fault diagnosis request for the target vehicle external speaker every preset diagnostic cycle and send the fault diagnosis request to the preset vehicle controller, so that the vehicle controller generates a fault detection signal when it receives the fault diagnosis request.

[0085] The judgment module is used to acquire the electrical signal data of the target vehicle's external speaker based on the fault detection signal, and to determine whether the current vehicle meets the preset fault conditions based on the electrical signal. If the fault conditions are met, the module determines the fault type and fault level of the target vehicle's external speaker.

[0086] The location acquisition module is used to generate a fault report for the target vehicle's external speaker based on the fault type and fault level, while simultaneously acquiring the actual location of the current vehicle.

[0087] The search module is used to search for the nearest vehicle repair shop or 4S store to the current vehicle based on the actual location, fault type and fault level, and generate a navigation route for the current vehicle to the vehicle repair shop or 4S store, and send the fault report and navigation route to the in-vehicle display and / or target terminal device.

[0088] Optionally, in one embodiment of this application, the device 10 for vehicles to share external speakers across different areas further includes: a detection module, a shouting module, and a reminder module.

[0089] The detection module is used to determine whether the current vehicle meets the preset fault conditions based on the electrical signal, and if the fault conditions are met, to determine the fault type and fault level of the target vehicle's external speaker. At the same time, it acquires images of the current vehicle's external environment and inputs these images into a pre-trained pedestrian detection model to output pedestrian detection data corresponding to the images.

[0090] The announcement module is used to determine whether the pedestrian detection data meets the preset driving safety conditions. If the pedestrian detection data does not meet the preset driving safety conditions, it generates a vehicle announcement mode activation request signal to activate the vehicle announcement mode of the current vehicle.

[0091] The reminder module is used to enable the target user to verbally remind at least one pedestrian in the current vehicle's environment through a vehicle-to-vehicle announcement mode.

[0092] Optionally, in one embodiment of this application, the playback module 300 includes: a first control unit, a second control unit, and a third control unit.

[0094] The second control unit is used to control the target external speakers to mute the cabin area when it receives a chassis domain horn sound source signal and an external media interaction sound source signal.

[0095] The third control unit is used to control the target external speaker to play mixed audio when it receives an in-vehicle audio source signal, an external media interactive audio source signal, or a chassis domain horn audio source signal.

[0096] Optionally, in one embodiment of this application, the generation module 200 includes a first analysis unit and a first acquisition unit.

[0097] The first analysis unit is used to determine whether the vehicle is currently in motion or stationary state based on the status information.

[0102] Optionally, in one embodiment of this application, the playback module 300 further includes an amplification unit and a fourth control unit.

[0103] The amplification unit is used to perform signal amplification operation on at least one cabin domain interactive audio source signal through a preset power amplifier when the current vehicle generates at least one cabin domain interactive audio source signal, so as to generate an amplified audio source signal corresponding to at least one cabin domain interactive audio source signal.

[0104] The fourth control unit is used to control the target vehicle external speaker to perform audio playback operation based on the audio source amplification signal and audio source management strategy.
