Referring to fig. 1, the present invention provides a method for controlling a sound source of a whole vehicle, which is applied to a vehicle-mounted terminal of a vehicle, and mainly includes the following steps:
s101: a first audio class is defined in advance for each sound source of the vehicle.
Different audio stream types (i.e. first audio class) are defined for different sources, such as: defining stream _ music class, aiming at a sound source of a player, comprising: carplay music, carlife music, cool me music, etc.; defining stream _ radio receiver class aiming at the sound source of the radio receiver; defining a stream _ notification class aiming at a sound source of a prompt tone; defining a stream _ a2dp Bluetooth audio class aiming at a Bluetooth sound source; defining a stream _ AUX interface music class aiming at a sound source from an AUX interface; defining a stream _ TTS TTS playing class aiming at a sound source of news playing; defining stream _ ring incoming call ring class aiming at the sound source of the incoming call ring; defining a stream _ bluetooth _ sco Bluetooth telephone class aiming at a sound source of a Bluetooth telephone; defining stream _ nav navigation prompt sound class aiming at a sound source of a navigation prompt; defining a stream _ VOIP telephone class aiming at a sound source comprising carplay equal telephones; defining a stream _ ivoka voice prompt class aiming at a sound source of a voice assistant, comprising: carplay siri, carpife voice assistant; the stream _ vehicle warning tone class is defined for a vehicle warning tone, a radar warning tone, and the like.
S102: and classifying the first audio classes into preset second audio classes according to application classes, wherein the second audio classes have predefined playing priorities.
In this embodiment, the preset second audio categories and their priorities are ordered from high to low as: vehicle class > communication class > voice assistant class > navigation class > notification class > media class. Accepting several defined audio stream types in S101, and classifying the first audio classes into preset second audio classes according to application categories, for example: stream _ vehicle is classified as a vehicle; stream _ bluetooth _ sco, stream _ voip and stream _ ring are classified into communication; classifying the stream _ ivoka into a voice assistant class; classifying stream _ nav into navigation class; classifying the stream _ notification as a notification class; stream _ music, stream _ radio, stream _ a2dp, stream _ aux are all categorized as media.
S103: and receiving a new playing request while playing the current sound source, and judging the priority of the sound source requested to be played.
S104: if the priority of the sound source requested to be played is higher than that of the current sound source, playing the sound source with the higher priority corresponding to the request, and recovering to the playing of the original sound source after the playing is finished.
In another embodiment, the current sound source is kept playing while the sound source with higher priority is switched to play, at this time, the volume of the current sound source is automatically decreased, and the difference between the volume of the current sound source and the volume of the sound source with higher priority reaches a preset threshold (such as a certain decibel value); and after the sound source with higher priority is played, the playing of the current sound source and the initial volume thereof are recovered. Further, the volume of the current sound source is changed along with the change of the volume of the sound source with higher priority, and the difference value of the preset threshold value is kept between the volume of the current sound source and the volume of the sound source with higher priority. For example: the sound source volume with higher priority is 21, and the volume of the initial sound source is 15; the sound source with the higher priority has a volume of 20, the original sound source has a volume of 14, and so on.
The following details the implementation of S104, taking over the priority setting in S102:
1) the vehicle class is higher priority than the media class: especially for the fault alarm sound of the vehicle, when the fault alarm sound of the vehicle occurs, the media is paused to play, and after the alarm sound is finished, the media class is recovered;
2) the communication class is higher priority than the media class: if the vehicle-mounted telephone calls, the media playing is suspended, and the media is resumed after the call is ended; furthermore, the communication class has a higher priority than the voice assistant class: if the voice assistant calls in the using process, the voice assistant automatically cancels, and the voice awakening is forbidden in the conversation process;
3) the voice assistant has priority over the media class: if the voice assistant wakes up, the media class is paused, and the media class resumes playing after the voice assistant is finished;
4) the navigation class is higher priority than the media class: if the navigation broadcasting process is carried out, the media type sound is reduced, or the media type sound is suspended, after the navigation broadcasting is finished, the media volume is recovered, and if the navigation volume is adjusted in the navigation broadcasting process, the media type sound can be correspondingly adjusted, so that the navigation sound and the media type sound can be ensured to keep a difference value and can be clearly heard by a driver; furthermore, the navigation class is prioritized over the notification class: if the navigation is occurring, the sound of the notification broadcast is lower than that of the navigation, so that the sound of the navigation can be clearly heard by the driver;
5) the notification class is higher priority than the media class: at this time, the notification sound can be mixed with the media sound without setting the volume difference between the notification sound and the media sound;
6) media class internal conflicts: only one media class is played at the same time, such as music and radio, which are mutually exclusive.
S105: and if the priority of the sound source requested to be played is lower than that of the current sound source, not responding to the request. It should be noted that the ordering of S104 and S105 is not sequential.
In another embodiment, the method further includes, before S102, presetting at least one vehicle-mounted terminal operating state and at least one vehicle operating change state, so that when the at least one vehicle-mounted terminal operating state and the at least one vehicle operating change state occur, the playing of the current sound source is suspended. For example:
1) when backing a car, the media sound is reduced or suspended, and after backing a car, the media sound is recovered;
2) when a system of the vehicle-mounted terminal enters a standby state, all sounds are suspended, and when the system is pushed out of the standby state, the sounds are recovered; further, navigation, voice assistants, etc. may not be restored; if the system enters a standby state in the conversation process, the Bluetooth is automatically switched into a private mode;
3) if the system of the vehicle-mounted terminal enters an AVN OFF state (the AVN is a vehicle-mounted host), all the sound is paused, and if the system returns to the AVN ON state again, the media class is resumed;
4) when the vehicle alarm sound occurs in the system of the vehicle-mounted terminal, the media is paused, and when the vehicle alarm fault is relieved, the media is resumed to be played.
In addition, the method provides the capability of automatic volume recovery, such as: if the volume is too high or too low when the computer is turned off last time, the volume is automatically restored to the specified value when the computer is turned on next time, specifically: when the defined volume is greater than 21 decibels, the volume of the next starting-up is automatically adjusted to 21 decibels; when the defined volume is less than 6, the volume is automatically adjusted to 6 decibels when the computer is started next time.
Besides, the method also limits the adjustment of the volume according to some abnormal states of the hardware of the vehicle-mounted terminal so as to protect the normal use of the hardware, such as: when the temperature of the system mainboard is too high, the volume adjustment of the system is limited to exceed 16 decibels and the like.
