[0030] Among them, the information of whether the user chooses to play the music application (APP) while playing the audiobook application (APP) is input into the perception module 1 through the in-vehicle infotainment system (IVI) 2; when the information input into the perception module 1 by the in-vehicle infotainment system (IVI) 2 is that the user chooses to play the music application (APP) while playing the audiobook application (APP), the perception module 1 determines whether there is only one driver in the cockpit; the perception module 1 inputs the information of whether there is only one driver in the cockpit to the in-vehicle infotainment system (IVI) 2; when the information input into the in-vehicle infotainment system (IVI) 2 is that there is only one driver in the cockpit, the in-vehicle infotainment system (IVI) 2 turns on the privacy mode; when the information input into the in-vehicle infotainment system (IVI) 2 is not that there is only one driver in the cockpit, the in-vehicle infotainment system (IVI) 2 determines whether the shared external speaker mode is turned on.
[0031] The in-vehicle infotainment system (IVI) 2 includes an in-vehicle dual-audio processing unit, an in-vehicle infotainment system (IVI) 2 host, and an in-vehicle infotainment system (IVI) 2 display. The in-vehicle dual-audio processing unit is used to process a first audio track and a second audio track, and is responsible for audio switching, mixing, and sound effect processing. The first audio track is used for an audiobook application (APP), and the second audio track is used for a music application (APP). Through precise timestamps and synchronization mechanisms, the first audio track and the second audio track can be seamlessly mixed and played to provide users with an audiobook experience with real-time background music. The in-vehicle infotainment system (IVI) 2 host is used to control an external power amplifier 3 to achieve interactive sound effects of independent audio.
[0032] The perception module 1 includes an occupant monitoring system (OMS) 11, a blind spot detection system (BSD) 12, and a vehicle controller 13. 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.
[0033] The vehicle-mounted 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 .
[0034] Figure 2 This 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 in-cockpit listening experience.
[0035] The following combination Figures 1 to 4 The working principle of the utility model system is as follows:
[0036] 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) for playback or opens the audiobook application (APP) and the music application (APP) for playback through the in-vehicle infotainment system (IVI) 2 display.
[0037] 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 as follows Figure 3 The content shown.
[0038] If the user opens the audiobook application (APP) and the 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 his or her 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 as follows Figure 4 The content shown.
[0039] If the user chooses to play an audiobook application (APP) and a music application (APP) simultaneously, the user can adjust the volume of the audiobook application (APP) and the music application (APP) independently to achieve a satisfactory listening experience. At the same time, the in-vehicle infotainment system (IVI) 2 will record the volume adjustment results of the user for the audiobook application (APP) and the music application (APP) and associate the volume adjustment results with the user account. The next time the user uses the car and plays the audiobook application (APP) and the music application (APP) simultaneously, 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 adjusted results. In addition, if the user sets the equalizer or selects a scene mode, the in-vehicle infotainment system (IVI) 2 can record them and automatically load them the next time the user uses the car.
[0040] When the user chooses to play the audiobook application (APP) and the music application (APP) at the same time, the in-vehicle infotainment system (IVI) host 2 will input the information that the user chooses to play the music application (APP) while playing the audiobook application (APP) to the occupant monitoring system (OMS) 11, and the occupant monitoring system (OMS) 11 will determine whether there is only one person in the cockpit, and input the information of whether there is only one person in the cockpit to the in-vehicle infotainment system (IVI) 2 host. When the in-vehicle infotainment system (IVI) 2 host receives the information that there is only one person in the cockpit, the in-vehicle infotainment system (IVI) VI)2 will turn on the privacy mode. When the in-vehicle infotainment system (IVI)2 host receives information that the driver is not the only one in the cockpit, the in-vehicle infotainment system (IVI)2 will determine whether the shared external speaker mode is turned on. If the in-vehicle infotainment system (IVI)2 host determines that the shared external speaker mode is turned on, the in-vehicle infotainment system (IVI)2 will automatically load the volume adjustment result of the last user for the audiobook application (APP) and the music application (APP), that is, the user preference, and play the audiobook application (APP) and the music application (APP) at the volume of the volume adjustment result, and the vehicle controller 1 3 will monitor the vehicle speed and feed back to the in-vehicle infotainment system (IVI) 2 host. If the vehicle speed is less than 30km / h, the in-vehicle infotainment system (IVI) 2 host will control the default volume to 20 decibels, and as the vehicle speed increases by 1km / h (the vehicle speed is always less than 30km / h), the in-vehicle infotainment system (IVI) 2 host will increase the volume by 1 decibel; if the vehicle speed is not less than 30km / h and not more than 60km / h, the in-vehicle infotainment system (IVI) 2 host will control the default volume to 40 decibels, and as the vehicle speed increases by 1km / h (the vehicle speed is always less than 60km / h), the in-vehicle infotainment system ( The in-vehicle infotainment system (IVI) 2 host increases the volume by 1 decibel, and as the vehicle speed decreases by 1 km / h (the vehicle speed is always not less than 30 km / h), the in-vehicle infotainment system (IVI) 2 host decreases the volume by 1 decibel; if the vehicle speed is greater than 60 km / h, the in-vehicle infotainment system (IVI) 2 host controls the default volume to 60 decibels, and as the vehicle speed increases by 1 km / h, the in-vehicle infotainment system (IVI) 2 host increases the volume by 1 decibel (the upper limit is 80 decibels), and as the vehicle speed decreases by 1 km / h (the vehicle speed is always greater than 60 km / h), the in-vehicle infotainment system (IVI) 2 host decreases the volume by 1 decibel.
[0041] Among them, when the aforementioned privacy mode is turned on, the occupant monitoring system (OMS) 11 will monitor whether other people get on the car, and the blind spot detection system (BSD) 12 will monitor whether there are people outside the car approaching. Specifically, when the occupant monitoring system (OMS) 11 monitors that other people get on the car, 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 playback volume; or when the blind spot detection system (BSD) 12 detects that someone outside the car approaches, 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 playback volume.
[0042] 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). The user's health management device monitors the user's physiological data (such as heart rate) and feeds it back to the in-vehicle infotainment system (IVI) 2. The in-vehicle infotainment system (IVI) 2 adjusts the volume of the audiobook application (APP) and the music application (APP) based on the feedback results. For example, when the user's health management device monitors the user's heart rate above 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.
[0043] The above description of the present invention is provided as an example, in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described method. Any non-substantial improvements based on the concepts and technical solutions of the present invention, or any application of the concepts and technical solutions of the present invention to other situations without modification, fall within the scope of protection of the present invention.
