[0028] See also Figure 1 In some embodiments of the present application, the present application provides an audio control system 10, comprising: a first audio module 20, a second audio module 30, a connection module 51, a judgment module 52, a decision module 53 and a control module 54. The first audio module 20 is used to provide sound to the driver. The second audio module 30 is used to provide sound to the entire vehicle. The connection module 51 is used to connect the audio control system 10 with the vehicle-mounted system 70 and the vehicle-external system 80. The judgment module 52 is used to determine the signal source of the connection module 51. The decision module 53 is used to determine the sound strategy according to the information from the judgment module 52. The control module 54 is configured to send a control instruction to at least one of the first audio module 20 and the second audio module 30 according to the sound strategy.

[0029] It is understandable that the connection module 51 is connected to the vehicle-mounted system 70 through a circuit or a communication module, and is connected to the external system through wireless communication, so that the audio control system 10 can obtain signals from the vehicle-mounted system 70 and the external system 80. The signal source of the connection module 51 is determined by the judgment module 52, and then the sound strategy is determined according to the signal source by the decision module 53. After the control module 54 obtains the sound strategy instruction, it makes the first sound module 20 and the second sound module 30 work according to the sound strategy, so that the vehicle-mounted audio system adopts different sound strategies according to different signal sources, so that the vehicle-mounted audio meets diverse needs.

[0030] Among them, when the signal source is the driver's call device, sound is provided to the driver through the first audio module 20, so as to facilitate the driver to realize voice calls and protect the driver's privacy; when the signal source is the navigation device, sound is provided to the driver through the first audio module 20, so as to avoid the navigation voice from interfering with other members in the car; when the signal source is the audio and video equipment, sound is provided to the entire vehicle through the second audio module 30, so that all passengers in the car can feel a good audio-visual experience; when the signal source is the notification system of the road administration or other units, sound is provided to all passengers in the vehicle through the second audio module 30, so that all members in the car can receive external notification information in time, and then respond accordingly according to the external notification information.

[0031] In this way, the car audio system can meet diverse needs.

[0032] In some application scenarios of the present application, during the driving process of the vehicle, it is usually necessary to navigate through a navigation device so that the vehicle and the people on the vehicle can smoothly reach the destination. In the process of navigation through a vehicle-mounted navigation device or an external navigation device, it is necessary to broadcast the navigation information through voice so that the driver can grasp the navigation information in time while observing the road conditions. Passengers in other passenger seats do not need to specifically grasp the navigation information of the vehicle, but if the navigation voice information is broadcast to the entire vehicle, it will interfere with the calls or rest of other passengers in the vehicle. In the process of navigation voice broadcast, the navigation voice broadcast is directed to the driver through the first audio module 20, thereby preventing the sound of the navigation voice broadcast from affecting other passengers in the vehicle.

[0033] When the navigation device is a vehicle-mounted navigation device, the audio control system 10 is connected to the vehicle-mounted navigation system via the connection module 51 through a wired or wireless transmission method. During navigation, the vehicle-mounted navigation device sends navigation voice information, and the judgment module 52 determines that the signal source is the vehicle-mounted navigation device. After the judgment module 52 judges the signal source, it sends the judgment result to the decision module 53. The decision module 53 determines the sound strategy based on the information from the judgment module 52, and then issues an instruction to enable the control module 54 to send a control instruction to the first audio module 20, so that the first audio module 20 generates sound according to the sound strategy, so that the navigation voice is directed to the driver.

[0034] Similarly, when the navigation device is an external navigation device, the audio control system 10 is connected to the vehicle navigation system via the connection module 51 through the transmission mode of wireless communication. During the navigation process, the external navigation device sends navigation voice information, and the judgment module 52 determines that the signal source is the external navigation device. After the judgment module 52 judges the source of the signal, it sends the judgment result to the decision module 53. The decision module 53 determines the sound strategy based on the information from the judgment module 52, and then issues an instruction to make the control module 54 send a control instruction to the first audio module 20, so that the first audio module 20 generates sound according to the sound strategy, so that the navigation voice is directed to the driver.

[0035] During the process of playing audio and video through the vehicle audio and video device, the audio control system 10 is connected to the vehicle audio and video device through the connection module 51. During the process of audio and video broadcasting, the vehicle audio and video device sends a sound signal, and the judgment module 52 determines that the signal source is the vehicle audio and video device. After the judgment module 52 judges the source of the signal, it sends the judgment result to the decision module 53. The decision module 53 determines the sound strategy based on the information from the judgment module 52, and then sends an instruction to make the control module 54 send a control instruction to the second audio module 30, so that the second audio module 30 generates sound according to the sound strategy, and the vehicle audio and video device broadcasts audio and video to the whole vehicle.

[0036] In some embodiments of the present application, the first audio module 20 includes a broadcast directional audio module 21 and a warning directional audio module 22. The broadcast directional audio module 21 is used for voice broadcast and call broadcast. The warning directional audio module 22 is used for warning broadcast of events in specific parts and directions of the vehicle.

[0037] It is understandable that, during the driving of the vehicle, the road condition information obtained by the navigation device and the navigation instructions issued are broadcasted through the broadcast directional audio module 21, so that the driver can obtain the information and instructions from the navigation device separately and clearly.

[0038] When the vehicle encounters abnormal situations such as about to cross the line, close to obstacles or people, and close distance between adjacent vehicles, the vehicle-mounted warning system will give early warning of the abnormal situation encountered by the vehicle, and send a warning signal to the audio control system 10 through the connection module 51. After the judgment module 52 determines that the source of the signal from the connection module 51 is the vehicle-mounted warning system, the decision module 53 determines the sound strategy based on the information from the judgment module 52, and then sends a control instruction to the warning directional audio module 22 through the control module 54 according to the sound strategy, so that the warning directional audio emits a warning sound from the corresponding direction according to the sound strategy, so as to remind the driver in which specific direction the vehicle will encounter an abnormal situation, so that the driver can clearly understand the direction where the vehicle will encounter the abnormality, so as to make correct driving decisions and improve the safety during driving.

[0039] In some embodiments of the present application, the announcement directional sound module 21 includes a left announcement directional sound and a right announcement directional sound, wherein the left announcement directional sound is arranged on the left side of the driver's headrest, and the right announcement directional sound is arranged on the right side of the driver's headrest. When the driver is in the driving position, the left announcement directional sound is directed toward the driver's left ear, and the right announcement directional sound is directed toward the driver's right ear.

[0040] It is understandable that the announcement directional audio module 21 is respectively arranged on both sides of the driver's headrest, so that the announcement directional audio module 21 is closer to the driver's ears, thereby reducing the propagation distance of the sound. The propagation distance of the announcement sound is shortened. On the one hand, the energy loss in the propagation process of the announcement sound is reduced, and the influence of interference factors on the announcement sound in the propagation process is reduced, so that the voice broadcast information received by the driver is clearer, ensuring that the driver can obtain the voice broadcast information more clearly and completely, and ensuring the safety of the driving process; on the other hand, the short-distance propagation enables the announcement directional audio module 21 to transmit the sound clearly and completely to the driver without high power consumption, thereby effectively reducing the power consumption of the announcement directional audio.

[0041] In the process of voice broadcasting through the broadcast directional sound module 21, the left broadcast directional sound and the right broadcast directional sound are used to broadcast from the left and right sides of the driver respectively, so that both ears of the driver can receive the broadcast sound, so that the broadcast sound received by the driver is clearer and more three-dimensional. When there is voice broadcast information in a direction, the left broadcast directional sound or the right broadcast directional sound can broadcast the voice information to the driver from the corresponding direction according to the corresponding direction.

[0042] In some application scenarios of the present application, when the navigation information is to turn left, the navigation device sends the corresponding navigation information to the audio control system 10 through the connection module 51. The judgment module 52 determines that the signal source is the navigation device, and the decision module 53 recognizes that the navigation information is to turn left, and then determines the voice strategy for making the left broadcast directional sound sound in combination with the information of the judgment module 52, and the control module 54 sends a control instruction to the left broadcast directional sound according to the voice strategy determined by the decision module 53, so that the left broadcast directional sound sends a voice broadcast about turning left to the driver from the left side of the driver. On the one hand, the driver is prompted with the exact direction of the left turn, so that the driver has a more accurate sense of the real spatial direction. On the other hand, the left direction, right direction and bidirectional broadcast modes are switched in real time, so that the driver receives more diverse information, reduces the risk of mental fatigue of the driver, and thus improves the safety of the driving process.

[0043] It is understandable that some drivers are not sensitive to the left and right directions, or are prone to confusion in spatial direction when they are tired, and will make wrong judgments about spatial direction under external interference. The left and right directional speakers broadcast from the left and right sides of the driver respectively, and then through directional voice broadcasts, the driver can accurately grasp the real-time navigation direction, avoid the driver's wrong judgment of spatial direction, and thus ensure the safety of the driving process.

[0044] In some embodiments of the present application, a left audio bracket and a right audio bracket are respectively installed on both sides of the driver's headrest. The left audio bracket is used to install the left broadcast directional audio, and the right audio bracket is used to install the right broadcast directional audio. The left audio bracket is provided with a left adjustment device, and the right audio bracket is provided with a right adjustment device. The left adjustment device is used to adjust the broadcast direction of the left broadcast directional audio, and the right adjustment device is used to adjust the broadcast direction of the right broadcast directional audio.

[0045] It can be understood that the broadcasting directions of the left broadcast directional audio system and the right broadcast directional audio system are adjusted respectively by the left adjustment device and the right adjustment device, so that the broadcasting direction of the broadcast directional audio module 21 can adapt to drivers of different body shapes and riding habits.

[0046] In some embodiments of the present application, the warning directional sound module 22 includes a right front warning directional sound, a front warning directional sound, a left front warning directional sound, a left front warning directional sound, a left rear warning directional sound, a right rear warning directional sound, and a right rear warning directional sound. Among them, the right front warning directional sound is set in the instrument panel area on the right side of the steering wheel, the front front warning directional sound is set in the instrument panel area in front of the driver's seat, the left front warning directional sound is set in the instrument panel area on the left side of the steering wheel, the left front warning directional sound is set in the door area on the left side of the driver's seat, the left rear warning directional sound is set in the left area of ​​the driver's seat, the rear rear warning directional sound is set in the center line area of ​​the driver's seat back, the right rear warning directional sound is set in the right area of ​​the driver's seat, and the right rear warning directional sound is set in the area on the side of the gear console facing the driver.

[0047] It is understandable that during the driving process, obstacles may appear in different directions of the vehicle. The vehicle-mounted warning system can detect obstacles approaching the vehicle, thereby avoiding collision between the vehicle and the obstacle. During the vehicle warning process, the vehicle-mounted warning system sends the detection result to the sound control system 10 through the connection module 51, and the judgment module 52 can judge that the signal source is the vehicle-mounted warning system. The decision module 53 recognizes that the signal source is the vehicle-mounted warning system, and then determines the sound strategy for making the warning directional sound module 22 sound in combination with the information of the judgment module 52. The control module 54 sends a control instruction to the warning directional sound module 22 according to the sound strategy determined by the decision module 53, so that the warning directional sound module 22 sends a warning sound about the approaching obstacle from the direction of the obstacle to the driver, so that the driver can accurately grasp the direction of the obstacle relative to the vehicle and the distance between the obstacle and the vehicle according to the warning sound, so that the driver can predict in advance from which direction the obstacle will collide with the vehicle, and then make timely and effective operations to avoid the occurrence of collision and improve the safety during driving.

[0048] In some application scenarios of the present application, when the vehicle gradually approaches the vehicle in front, the vehicle-mounted warning system detects the position and distance information of the vehicle in front through sensors or image recognition, and then sends information that an obstacle is approaching in front to the sound control system 10 through the connection module 51 according to the recognition result. The judgment module 52 determines that the source of the signal is the vehicle-mounted warning system, and the decision module 53 further determines the sound strategy for making the front warning directional sound sound according to the information from the judgment module 52. The control module 54 sends a control instruction to the front warning directional sound according to the sound strategy, so that the front warning directional sound emits a warning sound to the driver according to the information of the vehicle-mounted warning system, so that the driver can timely grasp the distance information between his own vehicle and the vehicle in front, and make corresponding driving operations in time to avoid the occurrence of rear-end collisions and ensure the safety of the driving process.

[0049] Similarly, when a vehicle is meeting another vehicle, changing lanes, moving or parking, the vehicle will approach an obstacle from different directions. When the onboard warning system detects that the distance between the vehicle and the obstacle reaches the warning threshold, the corresponding information is sent to the sound control system 10, so that the warning directional sound module 22 sends a warning sound to the driver from the corresponding direction according to the direction and distance of the obstacle, thereby reducing the risk of collision.

[0050] The volume, warning sound frequency and other parameters of the warning directional sound module 22 can be controlled to remind the driver of the distance between the vehicle and the obstacle, thereby further reducing the risk of collision. Among them, the sound emission strategy can be configured so that the closer the vehicle is to the obstacle, the louder the volume of the warning sound and the higher the frequency of the warning sound. When the distance between the vehicle and the obstacle reaches the collision threshold, the volume of the warning sound reaches the maximum, and the warning sound changes from an intermittent prompt sound to a long beep, thereby reminding the driver that a collision is about to occur. By setting the collision threshold, the driver can make a judgment in advance to avoid the occurrence of a collision.

[0051] In some embodiments of the present application, the warning directional sound module 22 includes a right front warning directional sound, a left front warning directional sound, a left rear warning directional sound, and a right rear warning directional sound. Among them, the right front warning directional sound is set in the instrument panel area on the right side of the steering wheel, the left front warning directional sound is set in the instrument panel area on the left side of the steering wheel, the left rear warning directional sound is set in the left area of ​​the driver's seat, and the right rear warning directional sound is set in the right area of ​​the driver's seat.

[0052] It can be understood that after the decision module 53 determines that the signal source is the vehicle-mounted warning system, it determines the sounding strategy according to the monitoring information from the vehicle-mounted warning system.

[0053] When the on-board warning system detects that an obstacle is approaching in front of the right side of the vehicle, the right front warning directional speaker will emit an alarm sound towards the driver. When the driver senses the alarm sound coming from the right front, he can judge that an obstacle is approaching in front of the right side of the vehicle; when the on-board warning system detects that an obstacle is approaching in front of the vehicle, the right front warning directional speaker and the left front warning directional speaker will emit an alarm sound towards the driver at the same time, so that the driver can sense that the sound signal comes from the front, and then the driver can judge that an obstacle is approaching in front of the vehicle; when the on-board warning system detects that an obstacle is approaching in front of the left side of the vehicle, the left front warning directional speaker will emit an alarm sound towards the driver. When the driver senses the alarm sound coming from the left front, he can judge that the vehicle When the on-board warning system detects that there are obstacles approaching in front of the right and left sides of the vehicle, the right front warning directional sounder and the left front warning directional sounder alternately emit alarm sounds in the direction of the driver, so that the driver can perceive the alarm sounds coming from the right front and the left front respectively within a safe time range, thereby allowing the driver to promptly know that there are obstacles in front of the left and right sides of the vehicle; when the on-board warning system detects that there is an obstacle approaching in front of the left rear of the vehicle, the left rear warning directional sounder emits an alarm sound towards the driver, and when the driver perceives the alarm sound coming from the left rear, he can judge that there is an obstacle approaching in the left rear of the vehicle; when the on-board warning system detects that there is an obstacle approaching to the direct left of the vehicle, the left front warning directional sounder and the left front warning directional sounder alternately emit alarm sounds in the direction of the driver, so that the driver can perceive the alarm sound coming from the right front and the left front respectively within a safe time range, thereby allowing the driver to promptly know that there are obstacles in front of the left and right sides of the vehicle; The rear warning directional speakers simultaneously emit alarm sounds in the direction of the driver, so that the driver can sense that the sound signal comes from the left, and then the driver can judge that there is an obstacle approaching to the left of the vehicle; when the on-board warning system detects that there are obstacles approaching both the left front and left rear of the vehicle, the left front warning directional speakers and the left rear warning directional speakers alternately emit alarm sounds in the direction of the driver, so that the driver can sense the alarm sounds coming from the left front and left rear respectively within a safe time range, and then the driver can promptly know that there are obstacles in the left front and left rear of the vehicle; when the on-board warning system detects that there is an obstacle approaching to the right rear of the vehicle, the right rear warning directional speakers emit alarm sounds towards the driver, and when the driver senses that there is an alarm to the right rear When the sound is heard, it can be judged that there is an obstacle approaching from the right rear of the vehicle; when the on-board warning system detects that there is an obstacle approaching from the rear of the vehicle, the left rear warning directional sound and the right rear warning directional sound simultaneously emit alarm sounds in the direction of the driver, so that the driver can sense that the sound signal comes from the rear, and then the driver can judge that there is an obstacle approaching from the rear of the vehicle; when the on-board warning system detects that there are obstacles approaching from both the left rear and the right rear of the vehicle, the left rear warning directional sound and the right rear warning directional sound alternately emit alarm sounds in the direction of the driver, so that the driver can sense the alarm sounds from the left rear and the right rear respectively within a safe time range, and then the driver can know in time that there are obstacles from the left rear and the right rear of the vehicle;When the vehicle warning system detects that an obstacle is approaching to the right of the vehicle, the right front warning directional sound and the right rear warning directional sound simultaneously sound alarms in the direction of the driver, so that the driver can sense that the sound signal comes from the right, and then the driver can judge that there is an obstacle approaching to the right of the vehicle; when the vehicle warning system detects that obstacles are approaching both to the right front and right rear of the vehicle, the right front warning directional sound and the right rear warning directional sound alternately sound alarms in the direction of the driver, so that the driver can sense the alarms coming from the right front and right rear respectively within a safe time range, and then the driver can know in time that there are obstacles in the right front and right rear of the vehicle. ;

[0054] By emitting the left front warning directional sound and the right front warning directional sound at the same time, the sound effect in front can be effectively simulated, and there is no need to configure an additional directional sound in front of the driver's seat, thereby reducing production costs and facilitating the layout of the vehicle's interior space. Similarly, by simulating a single channel with two channels, there is no need to configure additional directional sound to the left, rear, or right of the driver's seat, thereby further reducing production costs and making the vehicle's interior layout more reasonable.

[0055] In some embodiments of the present application, the number and installation positions of the warning directional audio modules 22 match the number and locations of the warnings provided by the vehicle warning system.

[0056] The information from the vehicle-mounted warning system is broadcasted by the warning directional sound module 22, so that the driver can obtain the warning information of the vehicle-mounted warning system in a timely and accurate manner, and then the driver can make accurate driving operations to ensure the safety of the vehicle during driving. Since the driver usually needs to concentrate on collecting road information outside the vehicle through vision to ensure driving safety during driving, the warning sound of the warning needs to be concise and accurate so that the driver can grasp the warning information in a timely and accurate manner. Therefore, the warning sound is configured as a loud buzzer, and the relevant parameters of the warning sound are configured to convey more abundant warning information. By matching the intermittent frequency and volume of the warning sound with the urgency of the warning information, the driver can judge the urgency of the warning information only by the received sound volume or intermittent frequency, without the need for complex semantic understanding, thereby ensuring the speed and accuracy of information transmission, and improving the driver's response speed and the safety of the driving process. The warning information of the corresponding position is broadcasted by the warning directional sound at different positions, so that the driver can grasp the warning information more accurately, which is convenient for the driver to make more correct judgments based on the warning information and improve the safety of the driving process.

[0057] The navigation voice is broadcasted through the broadcast directional audio module 21, so that the driver can obtain more comprehensive information about driving navigation. Since the navigation information is relatively complex, it is necessary to fully and accurately convey the navigation information through voice broadcasting, so that the driver can accurately make driving operation decisions based on the navigation information, ensuring the accuracy of the vehicle's travel direction and the safety of the driving process.

[0058] The warning information and navigation information are broadcasted respectively by the warning directional audio module 22 and the broadcast directional audio module 21, so that the driver can distinguish the warning information from the navigation information, reduce the risk of the driver making wrong driving decisions, and ensure driving safety.

[0059] Directional audio can propagate sound in a directional manner and can accurately control the direction and range of sound propagation. Therefore, by providing relevant sound information to the driver's seat through directional audio, the driver can clearly and accurately obtain relevant sound information without disturbing other passengers in the car. And when the driver needs to make a voice call, the directional audio sends sound information to the driver alone to protect the driver's privacy. It should be pointed out that since other passengers in non-driving seats do not need to drive the vehicle, they can easily choose the appropriate voice call method, and the call privacy issue is not obvious. Therefore, there is no need to specially set up directional audio to provide call voice information broadcasting for non-driving seat passengers, thereby reducing production costs and facilitating the layout of the vehicle's interior structure.

[0060] In some embodiments of the present application, an audio control system 10 provided by the present application further includes a third audio module 40, and the third audio module 40 is used to provide sound to each occupant in a non-driving seat.

[0061] A third audio module 40 is provided at each non-driving seat, so that each non-driving seat occupant can obtain sound information independently, thereby preventing the occupant who does not want to receive the sound of the audio system from being disturbed by the sound information. Different occupants have different needs for riding, some occupants need a quiet rest, some occupants need music information, some occupants need radio information, and some occupants need video and sound information. Therefore, through the third audio module 40, each occupant can independently operate the corresponding audio module, so that each occupant can configure the audio experience needs they need.

[0062] In some embodiments of the present application, the third audio module 40 includes a non-driving position directional audio module, and each non-driving position is configured with a set of non-driving position directional audio modules.

[0063] By installing a non-driving seat directional audio module on the headrest of each non-driving seat, the sound interference between non-driving seats can be avoided, thereby improving the experience of the passengers in the car.

[0064] In some embodiments of the present application, the second audio module 30 is provided with a plurality of speakers, each of which is disposed at a different position in the vehicle to achieve multi-channel stereo sound effects.

[0065] By arranging the speakers of the second audio module 30 at different positions in the vehicle, the second audio module 30 can emit sounds from different directions, thereby achieving a stereoscopic sound effect.

[0066] Through the cooperation between the second sound module 30 and the third sound module 40, the sound effects can be more diverse.

[0067] In some application scenarios of the present application, the sound emitted by the second audio module 30 is used as the background sound of the environment, and the sound emitted by the third audio module 40 is used as the event sound of a specific situation. Thus, through the cooperation between the second audio module 30 and the third audio module 40, the auditory experience of the passengers in the vehicle is made more realistic and three-dimensional.

[0068] When playing music through a music player, the audio signal of the music player is separated into background music and human voice through the track separation module, and the audio signal after track separation is sent to the sound control system 10 through the connection module 51, and the judgment module 52 can judge that the signal source of the audio signal is the music player and has been separated by the track. The decision module 53 determines the sound strategy based on the information from the judgment module 52. The control module 54 sends a control signal to the second sound module 30 and the third sound module 40 according to the sound strategy, so that the second sound module 30 and the third sound module 40 work according to the sound strategy.

[0069] The background music is played through the second sound module 30, and the human voice is played through the third sound module 40, and the volume of the human voice can be adjusted individually. When a passenger needs to hear the lyrics more clearly, the non-driving position operation module 6261 set at his seat can increase the sound of the third sound module 40 at his seat, so that he can hear the lyrics more clearly; and when other passengers do not want to hear the lyrics, they can also reduce or turn off the sound of the third sound module 40 at their seat through the non-driving position operation module 6261 at their seat, so that only the background music played by the second sound module 30 can be heard. In this way, the personalized needs of different passengers for music experience are met.

[0070] In some embodiments of the present application, the present application provides an audio control system 10 further comprising: a driver's seat operation module 61, a non-driver's seat operation module 6261, a voice operation module 63, and an authority allocation module 65. The driver's seat operation module 61 is used for the driver to control the audio control system 10. The non-driver's seat operation module 6261 is used for the non-driver's seat passenger to control the corresponding seat speaker. The voice operation module 63 is used to control the audio control system 10 by voice. The authority allocation module 65 is used for the driver to allocate operation authority or to allocate operation authority according to a preset authority allocation strategy.

[0071] The driver operates the sound control system 10 through the driving position operation module 61, so that the driver can independently create the voice broadcast mode that best suits him / herself, and then the driver can perform driving operations in the sound environment that best suits him / herself, thereby making the driver's driving experience easier, ensuring the accuracy and timeliness of the driver's driving operations, and improving driving safety.

[0072] Passengers in non-driving seats can operate the speakers of their own seats through the non-driving seat operation module 6261, thereby achieving personalized control over the volume of the speakers, opening and closing of the speakers, switching of signal sources, etc., thereby meeting the personalized needs of passengers in different seats and improving the passengers' riding experience.

[0073] Since the driver needs to concentrate most of his energy on driving operations during driving, frequent audio operations will distract the driver's attention, thus causing traffic accidents. The audio control system 10 is controlled by the voice operation module 63, so that the driver can operate the audio control system 10 without distracting the driver's effort, thereby improving the convenience and safety of operation.

[0074] The voice operation module 63 includes a microphone and a voice recognition unit, and the microphone is installed on the steering wheel.

[0075] By installing the microphone on the steering wheel, the microphone faces the driver, and the driver can clearly transmit voice information to the voice operation module 63 even in a noisy environment. When the microphone acquires external sound, the voice recognition unit matches the preset voice matching data, and then recognizes the driver's voice, so that the driver can operate the sound control system 10 through the voice operation module 63, and other noises do not match the preset voice matching data, and thus will not affect the voice operation module 63, thereby avoiding the noise from affecting the driver's voice operation, and ensuring the reliability and effectiveness of the voice operation.

[0076] The driver can allocate the operating authority of the audio control system 10 through the authority allocation module 65, so as to avoid adverse effects on the driver caused by other passengers in the car when operating the audio, while ensuring that other passengers can effectively operate the audio control system 10, thereby improving the car experience of other passengers.

[0077] In some application scenarios of the present application, the driver can allocate the video player sound operation permission, music player sound operation permission, radio sound operation permission, and second audio module 30 operation permission to the non-driving position operation module 6261 through the permission allocation module 65; and allocate the vehicle warning system sound operation permission, navigation system sound operation permission, and call system sound operation permission to the driving position operation module 61. In this way, the non-driving position operation module 6261 is prevented from affecting the voice broadcast about driving, preventing misoperation and ensuring the safety of the driving process.

[0078] In some embodiments of the present application, the authority allocation module 65 includes a selection button and an authority allocation button, and the selection button and the authority allocation button are both set at the thumb position of the steering wheel, and the selection button and the authority allocation button are respectively located on both sides of the steering wheel.

[0079] When the driver allocates authority during driving, the driver can press the selection button with the thumb of one hand to flip through and select different operating authorities. When flipping to the target operating authority, the driver can press the authority allocation button with the thumb of the other hand to flip through and select different operating modules. When flipping to the target operating module, the authority allocation button can be long pressed to confirm the allocation of the operating authority. In the process of flipping through the operating authority or operating module, the announcement directional audio module 21 can be provided to announce the operating authority or operating module, so that the driver knows which operating authority or operating module is currently flipped to. In this way, the operating authority of the audio control system 10 is allocated while reducing the impact on the driving operation, ensuring the safety of the driving process.

[0080] In some application scenarios of the present application, the sound operation authority of the radio is allocated to the non-driving seat operation module 6261.

[0081] The driver presses the selection button with the thumb of one hand. When the driver hears the voice broadcast for the radio, he stops pressing the selection button and presses the authority allocation button with the thumb of the other hand. When the driver hears the voice broadcast for the non-driving seat operation module 6261, he long presses the authority allocation button to confirm the allocation of the radio sound operation authority to the non-driving seat operation module 6261.

[0082] In some embodiments of the present application, the audio control system 10 provided by the present application further includes a passenger seat operation module 64 , and the passenger seat operation module 64 is used for the passenger in the passenger seat to assist in operating the audio control system 10 .

[0083] During the driving process, the driver needs to focus on driving operations to ensure driving safety. The passenger in the front passenger seat is closest to the driver and the central control area, so he can assist the driver in auxiliary group operations. The driver can assign the corresponding operation rights to the front passenger seat operation module 64 through the authority allocation module 65 so that the passenger in the front passenger seat can perform auxiliary operations.

[0084] The passenger seat operation module 64 includes a touch screen operation module and a button operation module. The passenger seat can perform auxiliary operations through the touch screen operation module and the button operation module. When other passengers in the car have operation requirements, the requirements can be notified to the passenger seat to meet the needs of other passengers in the car.

[0085] In some application scenarios of the present application, when the passenger in the front passenger seat needs to assist in operating the audio operation of the navigation system, the driver can allocate the voice operation authority of the navigation system to the front passenger seat operation module 64 through the authority allocation module 65. After the voice operation authority of the navigation system is allocated to the front passenger seat operation module 64, the navigation system sound channel is allocated to the directional audio of the front passenger seat, so that the driver and the passenger in the front passenger seat can hear the navigation information at the same time. The passenger in the front passenger seat can control and operate the audio of the navigation system. The control and operation of the audio of the navigation system includes turning up the volume, turning down the volume, and redistributing the voice authority.

[0086] When other members in the car need to pay attention to the navigation information, they can inform the passenger in the front passenger seat, so that the passenger in the front passenger seat can allocate the sound authority of the navigation system to the corresponding non-driving seat directional audio through the front passenger seat operation module 64, and allocate the navigation system channel to the corresponding non-driving seat directional audio, so that the passenger in the non-driving seat can obtain the navigation voice information.

[0087] When the passenger seat operation module 64 obtains the voice operation authority of the navigation system, the passenger in the passenger seat can obtain the voice broadcast of the navigation system, which can assist the driver in observing the road conditions and assist the driver in driving operations according to the navigation information, thereby reducing the risk of traffic accidents caused by driver negligence and improving driving safety.

[0088] On the other hand, see Figure 2 The present application also provides a sound control method for controlling the sound control system 10 provided in the present application, comprising the following steps: S1, obtain external signal; S2. Determine the signal source of the external signal to obtain a determination result; S3, determine the vocalization strategy based on the judgment result; S4, controlling the first sound module 20 and the second sound module 30 according to the sound generation strategy; The first sound module 20 is used to provide sound to the driver, and the second sound module 30 is used to provide sound to the entire vehicle.

[0089] It is understandable that the external signal is a signal sent by a device other than the audio control system 10 , including a signal sent by the vehicle-mounted system 70 and a signal sent by the off-vehicle system 80 .

[0090] The vehicle-mounted system 70 or the vehicle-external system 80 sends a signal to the sound control system 10 through the connection module 51, and then the source of the external signal is determined through the judgment module 52. The decision module 53 determines the sound strategy according to the information of the judgment module 52, and the control module 54 sends a control instruction to the first sound module 20 and the second sound module 30 according to the sound strategy, so that the first sound module 20 and the second sound module 30 play the corresponding sound information according to the sound strategy, so that the vehicle-mounted sound system adopts different sound strategies according to different signal sources, so that the vehicle-mounted sound system can meet diverse needs. Among them, when the signal source is the driver's call device, sound is provided to the driver through the first audio module 20, so as to facilitate the driver to realize voice calls and protect the driver's privacy; when the signal source is the navigation device, sound is provided to the driver through the first audio module 20, so as to avoid the navigation voice from interfering with other members in the car; when the signal source is the audio and video equipment, sound is provided to the entire vehicle through the second audio module 30, so that all passengers in the car can feel a good audio-visual experience; when the signal source is the notification system of the road administration or other units, sound is provided to all passengers in the vehicle through the second audio module 30, so that all members in the car can receive external notification information in time, and then respond accordingly according to the external notification information.

[0091] In this way, the car audio system can meet diverse needs.

[0092] See also Figure 3 , in some embodiments of the present application, the judgment result includes: the signal source is from at least one of a navigation system, a call system, and a vehicle warning system; The first sound module 20 includes a broadcast directional sound module 21 and a warning directional sound module 22; The voice strategy includes the following steps: S31. Determine the direction and quantity of signal sources; S321, if the number of signal sources is one, sending a control instruction to a corresponding audio module according to the direction of the signal source; S322, if the number of signal sources is at least two, determining the priorities of the signal sources, and sending control instructions to the audio modules corresponding to the guidance of the signal sources respectively according to the priorities of the signal sources; If the signal source is a navigation system, the corresponding sound module includes a directional broadcast sound module 21; If the opposite direction of the signal source is a communication system, the corresponding sound module includes a broadcast directional sound module 21; If the signal source is directed to a vehicle-mounted warning system, the corresponding sound module includes a warning directional sound module 22 .

[0093] By identifying the information of the judgment module 52, the direction and number of the signal sources are determined. When the number of signal sources is one, a control instruction is sent to the corresponding audio module according to the direction of the signal source, so that the corresponding audio module plays the audio data from the signal source. When the number of signal sources is at least two, the priority of the signal source is determined according to the direction of the signal source, and then the control instructions are sent to the audio modules corresponding to the signal source according to the priority of the signal source. The volume of the audio can be controlled according to the different priorities; and the audio signal with higher priority can also be played first according to the different priorities.

[0094] By configuring the priority, the audio control system 10 is prevented from having audio playback confusion, the conflict between different audio signal sources is reduced, and the driver is ensured to be able to clearly and timely obtain important audio information, thereby ensuring the safety of the driving process.

[0095] In some embodiments of the present application, the priority of the signal source is configured as follows: the priority of the vehicle warning system takes precedence over the priority of the navigation system, and the priority of the navigation system takes precedence over the priority of the call system.

[0096] By making the audio control system 10 give priority to playing the audio signal from the vehicle-mounted warning system, thereby reducing the interference of other sounds on the warning prompt sound of the vehicle-mounted warning system, the driver can obtain the warning prompt sound in a timely and accurate manner, and make driving operation decisions based on the warning prompt sound, thereby reducing the risk of traffic accidents and ensuring safety during driving.

[0097] When the vehicle approaches an obstacle, the risk of collision increases. If the obstacle reaches the detection range of the vehicle-mounted warning system, the vehicle-mounted warning system sends a corresponding audio signal, which in turn makes the warning directional audio module 22 sound, so that the driver can obtain the warning information in time. If the navigation system also sends an audio signal at this time, which makes the broadcast directional audio module 21 sound, in this case, since the priority of the vehicle-mounted warning system takes precedence over the priority of the navigation system, when the audio information of the vehicle-mounted warning system and the navigation system are broadcast at the same time, the sound of the broadcast directional audio module 21 is automatically turned down, and the sound of the warning directional audio module 22 is automatically turned up, thereby reducing the interference of the navigation sound with the warning sound.

[0098] Since the vehicle warning system sends out a warning audio signal, indicating that the vehicle is in a relatively emergency state, the driver should not make voice calls with the outside world. The priority of the vehicle warning system should be given priority over the call system, thereby avoiding the driver's attention from making voice calls when the vehicle is in an emergency state. The driver can concentrate on dealing with the emergency situation currently facing the vehicle, thereby improving the safety of the driving process.

[0099] Since the navigation system is mainly used for road navigation and voice calls will distract the driver, the priority of the navigation system is configured to take precedence over the call system, thereby reducing the interference of voice calls on the driving process.

[0100] In some embodiments of the present application, a call priority button is provided on the steering wheel of the driver's seat. When the call priority button is pressed, the priority of the call system is increased.

[0101] Under good road conditions, when a voice call is connected, you can safely press the call priority button to increase the priority of the call system, thereby ensuring the call quality of the driver's voice call under safe conditions.

[0102] On the other hand, the present application also provides a vehicle-mounted audio system, including the audio control system 10 provided in the present application.
