The in-vehicle infotainment system (IVI) 2 is respectively connected to the occupant monitoring system (OMS) 11, the blind spot detection system (BSD) 12, and the vehicle controller 13. Specifically, the host of the in-vehicle infotainment system (IVI) 2 is respectively connected to the occupant monitoring system (OMS) 11, the blind spot detection system (BSD) 12, and the vehicle controller 13.

[0045] The vehicle speaker system 4 includes a first headrest speaker 41 , a second headrest speaker 42 , a center speaker 43 , a first speaker 44 , a second speaker 45 , a third speaker 46 , and a fourth speaker 47 .

[0046] Figure 2 The flowchart of a control method of a vehicle audio system for optimizing the cabin listening experience of the present invention comprises the following steps:

[0047] S1: Open the audiobook application (APP) and the music application (APP); Figure 2 Specifically, after the user enters the car cabin, when the user needs to listen to a book or needs to play background music while listening to a book, the user opens the audiobook application (APP) to play or opens the audiobook application (APP) and the music application (APP) to play through the in-vehicle infotainment system (IVI) 2 display screen.

[0048] S2: Determine through the in-vehicle infotainment system (IVI) 2 whether the user chooses to play the music application (APP) while playing the audiobook application (APP). If so, enter S3; if not, enter S5; that is, corresponding Figure 2 Specifically, if the user opens the audiobook application (APP) and the music application (APP) for playing, then enter S3, if the user only opens the audiobook application (APP) for playing, then enter S5.

[0049] If the user opens an audiobook application (APP) and a music application (APP) for playback, but the user opens the audiobook application (APP) first and then the music application (APP), the playback volume of the audiobook application (APP) is adaptively reduced through the control of the in-vehicle infotainment system (IVI) 2 host, and the in-vehicle infotainment system (IVI) 2 host sends information on whether the audiobook application (APP) needs to be closed to the in-vehicle infotainment system (IVI) 2 display screen, and the in-vehicle infotainment system (IVI) 2 display screen displays a pop-up window. The user can choose whether to close the audiobook application (APP) according to his or her needs through the content displayed in the pop-up window on the in-vehicle infotainment system (IVI) 2 display screen. Among them, the content displayed in the pop-up window can be such as Figure 4 The content shown.

[0050] If the user opens an audiobook application (APP) and a music application (APP) for playback, but if the user opens the music application (APP) first and then the audiobook application (APP), the playback volume of the music application (APP) is adaptively reduced through the control of the in-vehicle infotainment system (IVI) 2 host, and the in-vehicle infotainment system (IVI) 2 host sends information on whether the music application (APP) needs to be closed to the in-vehicle infotainment system (IVI) 2 display, and the in-vehicle infotainment system (IVI) 2 display displays a pop-up window. The user can choose whether to close the music application (APP) according to their needs through the content displayed in the pop-up window on the in-vehicle infotainment system (IVI) 2 display. Among them, the content displayed in the pop-up window can be such as Figure 5 The content shown.

[0051] Among them, if the user chooses to play the audiobook application (APP) and the music application (APP) at the same time, the user can independently adjust the volume of the audiobook application (APP) and the music application (APP) to achieve a satisfactory listening experience for the user. At the same time, the in-vehicle infotainment system (IVI) 2 will record the volume adjustment results of the audiobook application (APP) and the music application (APP) by the user this time, and associate the volume adjustment results with the user account. When the user uses the car next time and plays the audiobook application (APP) and the music application (APP) at the same time, the in-vehicle infotainment system (IVI) 2 will automatically load the volume adjustment results and play the audiobook application (APP) and the music application (APP) at the volume of the volume adjustment results. In addition, if the user sets the equalizer or selects the scene mode, the in-vehicle infotainment system (IVI) 2 can record them and automatically load them when the user uses them next time.

[0052] S3: Determine whether there is only one person in the cabin through the perception module 1. If not, enter S4. If yes, enter S6. Figure 2S3 in the process. Specifically, the information of whether the user chooses to play the music application (APP) while playing the audiobook application (APP) in S2 is inputted into the occupant monitoring system (OMS) 11 through the in-vehicle infotainment system (IVI) host 2. When the information inputted into the occupant monitoring system (OMS) 11 by the in-vehicle infotainment system (IVI) 2 host is that the user chooses to play the music application (APP) while playing the audiobook application (APP) in S2, the occupant monitoring system (OMS) 11 determines whether there is only one driver in the cockpit, and the information of whether there is only one driver in the cockpit is inputted into the in-vehicle infotainment system (IVI) 2 host through the occupant monitoring system (OMS) 11. When the information inputted into the in-vehicle infotainment system (IVI) 2 host by the occupant monitoring system (OMS) 11 is that there is only one driver in the cockpit, S6 is entered. When the information inputted into the in-vehicle infotainment system (IVI) 2 host by the occupant monitoring system (OMS) 11 is not that there is only one driver in the cockpit, S4 is entered.

[0053] S4: Determine whether the shared external speaker mode is on through the in-vehicle infotainment system (IVI) 2. If so, enter S8; if not, enter S7; Figure 2 Specifically, the host of the in-vehicle infotainment system (IVI) 2 determines whether the shared external speaker mode is turned on, and if so, enters S8, and if not, enters S7.

[0054] S5: Play the audiobook application (APP) alone and enter S8; corresponding Figure 2 S5 in.

[0055] S6: Enable privacy mode through the in-vehicle infotainment system (IVI) 2 and enter S8; Figure 2 S6 in the above. When the privacy mode is turned on, the occupant monitoring system (OMS) 11 monitors whether other people get on the vehicle, and the blind spot detection system (BSD) 12 monitors whether someone outside the vehicle is approaching. Specifically, when the occupant monitoring system (OMS) 11 monitors that other people get on the vehicle, the occupant monitoring system (OMS) 11 sends information to the in-vehicle infotainment system (IVI) 2 host, and then the in-vehicle infotainment system (IVI) 2 host controls to reduce the volume of the playback; or when the blind spot detection system (BSD) 12 monitors that someone outside the vehicle is approaching, the blind spot detection system (BSD) 12 sends information to the in-vehicle infotainment system (IVI) 2 host, and then the in-vehicle infotainment system (IVI) 2 host controls to reduce the volume of the playback.

[0056] S7: Play the audiobook application (APP) and music application (APP) by connecting Bluetooth headphones, and enter S8; that is, the corresponding Figure 2Specifically, when the in-vehicle infotainment system (IVI) 2 host determines in S4 that the shared external speaker mode is not turned on, the user can play the audiobook application (APP) and the music application (APP) by connecting the Bluetooth headset.

[0057] S8: The volume of the audiobook application (APP) and the music application (APP) is adjusted through the in-car audio system for optimizing the in-cabin audiobook experience; Figure 2 S8 in the above. Specifically, the volume adjustment result of the last user on the audiobook application (APP) and the music application (APP) recorded by the in-vehicle infotainment system (IVI) 2, i.e., the user preference, is automatically loaded, and the audiobook application (APP) and the music application (APP) are played at the volume of the volume adjustment result. If the user does not choose to play the music application (APP) in S2, the volume adjustment result of the last user on the audiobook application (APP) recorded by the in-vehicle infotainment system (IVI) 2, i.e., the user preference, is automatically loaded, and the audiobook application (APP) is played at the volume of the volume adjustment result. The vehicle speed is monitored by the vehicle controller 13 and fed back to the in-vehicle infotainment system (IVI) 2 host. If the vehicle speed is less than 30 km / h, the in-vehicle infotainment system (IVI) 2 host controls the default volume to 20 decibels, and as the vehicle speed increases by 1 km / h (the vehicle speed is always less than 30 km / h), the in-vehicle infotainment system (IVI) 2 host increases the volume by 1 decibel; if the vehicle speed is not less than 30 km / h and not more than 60 km / h, the in-vehicle infotainment system (IVI) 2 host controls the default volume to 40 decibels, and as the vehicle speed increases by 1 km / h (the vehicle speed is always less than 60 km / h), the in-vehicle infotainment system (IVI) 2 host increases the volume by 1 decibel. The in-vehicle infotainment system (IVI) 2 host will increase the volume by 1 decibel, and with each decrease of 1km / h in vehicle speed (the vehicle speed is always not less than 30km / h), the in-vehicle infotainment system (IVI) 2 host will decrease the volume by 1 decibel; if the vehicle speed is greater than 60km / h, the in-vehicle infotainment system (IVI) 2 host will control the default volume to 60 decibels, and with each increase of 1km / h in vehicle speed, the in-vehicle infotainment system (IVI) 2 host will increase the volume by 1 decibel (the upper limit is 80 decibels), and with each decrease of 1km / h in vehicle speed (the vehicle speed is always greater than 60km / h), the in-vehicle infotainment system (IVI) 2 host will decrease the volume by 1 decibel.

[0058] Figure 3It is a schematic diagram of the position distribution of the speaker system 4 in the system of the present invention. If the user opens the audiobook application (APP) and the music application (APP) for playback, the first headrest speaker 41, the second headrest speaker 42, and the center speaker 43 are controlled by the in-vehicle infotainment system (IVI) 2 host to play the audiobook, and the first speaker 44, the second speaker 45, the third speaker 46, and the fourth speaker 47 are controlled by the in-vehicle infotainment system (IVI) 2 host to play the music, thereby achieving stereo sound effects and enhancing the user's cockpit listening experience.

[0059] In addition, the in-vehicle infotainment system (IVI) 2 of the present invention is also integrated with the user's health management device (such as a smart watch, etc.), and the user's physiological data (such as heart rate, etc.) is monitored by the user's health management device and fed back to the in-vehicle infotainment system (IVI) 2, and the in-vehicle infotainment system (IVI) 2 adjusts the volume of the audiobook application (APP) and the music application (APP) according to the feedback results. For example, when the user's health management device monitors that the user's heart rate is higher than 110 beats per minute, the playback volume of the audiobook application (APP) and the music application (APP) is reduced through the in-vehicle infotainment system (IVI) 2 host.

[0060] The present invention is described above by way of example in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-mentioned methods. As long as various non-substantial improvements are made using the method concept and technical solution of the present invention; or the above concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the protection scope of the present invention.
