[0036] Below, several special situations that may occur when a mobile terminal (such as a smart phone, tablet computer, etc.) maintains a wireless communication connection with the vehicle-mounted system are first described.

[0037] When the vehicle is driving, the driver's mobile terminal is wirelessly connected to the vehicle system (for example, wirelessly connected to the vehicle system by Bluetooth, radio frequency (RF), etc.) and plays music through the vehicle system, and the driver and passengers enjoy the music played at the same time. If the driver stops temporarily and leaves the vehicle with the mobile terminal without turning off the vehicle, goes shopping or sends and receives express delivery, etc., since the distance between the mobile terminal and the vehicle (i.e., the vehicle system) does not exceed the wireless communication distance, the mobile terminal and the vehicle system can maintain a wireless communication connection. At this time, if the mobile terminal receives an incoming call (for example, but not limited to a phone call, WeChat call, etc.), and the driver operates the mobile terminal to answer the call, the following two situations may occur. In one case, since the mobile terminal and the vehicle system still maintain a wireless communication connection, the mobile terminal will not output sound, and the sound will be output through the vehicle system, and the vehicle system stops playing music. At this time, the driver needs to manually disconnect the wireless communication connection between the mobile terminal and the vehicle system to answer the call normally, but the passengers will not be able to enjoy the music at this time. Another situation is that the mobile terminal automatically switches the audio input / output device to the mobile terminal when leaving the vehicle, and the driver can answer calls normally, but when the driver leaves the vehicle, the vehicle system will interrupt the music playback, so that the passengers will not be able to enjoy the music.

[0038] On the other hand, when the vehicle is driving, the driver's mobile terminal is wirelessly connected to the vehicle system and plays music through the vehicle system, and the driver and passengers enjoy the music played at the same time. If the mobile terminal receives an incoming call and the driver chooses to answer it, the vehicle system will interrupt the music playback and output the incoming call. At this time, if the driver finds that the incoming call is very important and it is inconvenient to continue the call in the vehicle (that is, he does not want the passengers to hear it), but needs to be handled immediately. The driver will stop the car temporarily, leave the vehicle, and continue the call. At this time, the following two situations may occur. In one case, the driver manually disconnects the wireless communication connection between the mobile terminal and the vehicle system in order to answer the call normally. In another case, the audio input / output device is automatically switched to the mobile terminal when the mobile terminal leaves the vehicle, and the driver can answer the call normally. However, in both cases, the vehicle system will interrupt the music playback, so that the passengers will not be able to enjoy the music.

[0039] Figure 1 The present invention is a flowchart showing a method for selecting an audio input / output device of an application when a mobile terminal leaves a vehicle while maintaining a wireless communication connection with an in-vehicle system.

[0040] Reference Figure 1In step S101, a wireless communication connection (such as but not limited to Bluetooth connection, RF connection, etc.) is established between the mobile terminal and the vehicle-mounted system of the vehicle. For example, when the driver carries the mobile terminal into the vehicle and the wireless connection function of the mobile terminal is turned on, the wireless terminal can establish a wireless communication connection with the vehicle-mounted system. In this case, the applications with audio input / output functions running in the wireless terminal are all input / output through the vehicle-mounted system as an audio input / output device.

[0041] In step S102, the mobile terminal leaves the vehicle and maintains a wireless communication connection with the vehicle-mounted system. Here, the mobile terminal can detect whether it has left the vehicle by, for example, but not limited to, UWB positioning technology. In addition, the mobile terminal maintains a wireless communication connection with the vehicle-mounted system, which means that the distance between the mobile terminal and the vehicle-mounted system does not exceed the wireless communication distance.

[0042] In step S103, the mobile terminal disconnects the wireless communication connection with the in-vehicle system according to the user operation, thereby switching the audio input / output device of the application with audio input / output function to the mobile terminal.

[0043] In step S104, applications with audio input / output functions perform audio input / output through the mobile terminal, while the in-vehicle system does not perform audio input / output.

[0044] according to Figure 1 In the method of selecting the audio input / output device of the application shown, when the mobile terminal leaves the vehicle while maintaining a wireless communication connection with the vehicle-mounted system, if the wireless communication connection between the mobile terminal and the vehicle-mounted system is not manually disconnected, the application cannot perform audio input / output through the mobile terminal. If the wireless communication connection between the mobile terminal and the vehicle-mounted system is disconnected, the audio input / output of the application is all performed through the mobile terminal, and the vehicle-mounted system cannot perform audio input / output. As a result, the user of the mobile terminal needs to manually switch the audio input / output device, which is very inconvenient and cannot provide a good experience for the passengers in the car.

[0045] To this end, an embodiment of the present disclosure provides a method for automatically selecting an audio input / output device for an application. When a mobile terminal leaves a vehicle while maintaining a wireless communication connection with an in-vehicle system, the audio input / output device for an application with an audio input / output function is automatically selected according to the following preset rules: (1) When the mobile terminal leaves the vehicle, an input / output priority policy is initiated to determine the privacy applications and non-privacy applications among multiple applications with audio input / output functions currently running in the mobile terminal, and the mobile terminal is automatically selected as the audio input / output device for the privacy application; (2) When a new application with an audio input / output function is started in the mobile terminal, it is determined whether the input / output priority policy has been enabled, and if the input / output priority policy has been enabled, the operating device (e.g., the mobile terminal or the in-vehicle system) that starts the new application is automatically selected as the audio input / output device for the new application.

[0046] Below, refer to Figures 2 to 7 A method and apparatus, a medium, and a mobile terminal for automatically selecting an audio input / output device of an application according to an embodiment of the present disclosure are described in detail.

[0047] Figure 2 1 is a flow chart showing a method for automatically selecting an audio input / output device of an application according to an embodiment of the present disclosure. The method may be executed by a CPU of a mobile terminal, but is not limited thereto. For example, the method may be executed by other processors provided in the mobile terminal.

[0048] like Figure 2 As shown, in step S201, a wireless communication connection is established between the mobile terminal and the vehicle-mounted system of the vehicle. As described above, when the driver carries the mobile terminal into the vehicle and the wireless connection function of the mobile terminal is turned on, the wireless terminal can establish a wireless communication connection (for example, but not limited to Bluetooth connection, RF connection, etc.) with the vehicle-mounted system. The wireless terminal may include a smart phone, a tablet computer, etc., and may run multiple applications (Apps), such as phone, WeChat, navigation, SMS, address book, etc.

[0049] In step S202, in response to the occurrence of a preset event, the audio input / output device of the application on the mobile terminal is automatically selected according to a preset rule. According to an embodiment of the present disclosure, the preset event may include: the mobile terminal leaves the vehicle while maintaining a wireless communication connection with the vehicle system, or a new application on the mobile terminal is started after the mobile terminal leaves the vehicle while maintaining a wireless communication connection with the vehicle system. Alternatively, as described above, whether the mobile terminal leaves the vehicle may be detected by, for example, but not limited to, UWB positioning technology.

[0050] According to an embodiment of the present disclosure, the audio input / output device of the application on the mobile terminal can be selected based on the two rules as described above. Figure 3 and Figure 4 This is described in detail.

[0051] Figure 3 1 is a flowchart showing an example of a method for automatically selecting an audio input / output device of an application on a mobile terminal according to a preset rule according to an embodiment of the present disclosure. In this embodiment, the preset event is that the mobile terminal leaves the vehicle while maintaining a wireless communication connection with the vehicle-mounted system.

[0052] Reference Figure 3 In step S301, one or more applications with audio input / output functions currently running on the mobile terminal may be determined as target applications. Here, a list of all applications currently running on the mobile terminal may be first obtained, and then one or more applications with audio input / output functions may be determined from the obtained list of all applications. Generally speaking, there must be an application with audio input / output functions running on the mobile terminal. For example, when the mobile terminal establishes a wireless communication connection with the vehicle-mounted system, a music application may be started, and audio input / output may be performed through the vehicle-mounted system as an audio input / output device. However, the present disclosure is not limited thereto. If no application with audio input / output functions is running on the mobile terminal, the program may be exited. Figure 3 The method shown.

[0053] Next, in step S302, the mobile terminal may be automatically selected as the audio input / output device of the privacy application in the target application, and the vehicle system may be selected as the audio input / output device of the non-privacy application in the target application. In this way, on the one hand, it is possible to prevent passengers in the vehicle from understanding the audio output content of the privacy application, and prohibit passengers in the vehicle from participating in the audio input of the privacy application, thereby ensuring the security of the privacy application; on the other hand, passengers in the vehicle can still understand the audio output content of the non-privacy application, for example, passengers in the vehicle can still enjoy the audio output of the music application which is a non-privacy application.

[0054] According to an embodiment of the present disclosure, a privacy application may be an application that satisfies at least one of the following preset conditions: having an audio input function; being pre-set by the user. Examples of applications with an audio input function may include WeChat, a phone, etc., which are in a voice call. Pre-set privacy applications may include whitelist applications that are the default of the mobile terminal and privacy-preserving applications that are pre-set by the user. In this way, the user may freely set applications that require privacy protection to improve the security of the application.

[0055] In addition, if Figure 3The method shown may also include the following steps: in response to the mobile terminal leaving the vehicle while maintaining a wireless communication connection with the vehicle-mounted system, starting the input / output preference strategy to allow the audio input / output device of the application on the mobile terminal to be selected according to the preset rules; in response to the mobile terminal disconnecting the wireless communication connection with the vehicle-mounted system or returning to the vehicle, closing the input / output preference strategy to prohibit the audio input / output device of the application on the mobile terminal from being selected according to the preset rules. For example, before determining the target application, the input / output preference strategy may be started, and the input / output forced switching flag may be set; after the mobile terminal is automatically selected as the audio input / output device of the privacy application and / or after the vehicle-mounted system is selected as the audio input / output device of the non-privacy application, the input / output forced switching flag may be cleared. On the other hand, if the mobile terminal leaves the vehicle while maintaining a wireless communication connection with the vehicle-mounted system, but when the mobile terminal disconnects the wireless communication connection with the vehicle-mounted system (for example, the distance between the mobile terminal and the vehicle-mounted system exceeds the wireless communication distance, or the user manually disconnects the wireless communication connection) or returns to the vehicle (for example, detected by UWB positioning technology), the input / output preference strategy may be closed. By enabling / disabling the input / output preference strategy, the switching of the audio input / output device of the application can be avoided when it is not necessary, thereby ensuring the reliability of selecting the audio input / output device. On the other hand, by setting / clearing the input / output forced switching flag, the conflict between the two rules described above can be avoided.

[0056] Further, when the input / output preference strategy is started and the input / output forced switching flag is set, in step S302, in response to the input / output forced switching flag being set, the mobile terminal can be automatically selected as the audio input / output device of the privacy application, and the vehicle-mounted system can be selected as the audio input / output device of the non-privacy application. That is, when the mobile terminal leaves the vehicle while maintaining a wireless communication connection with the vehicle-mounted system, the input / output preference strategy can be automatically started, and then the input / output forced switching flag can be set to true, and then the automatic selection of the audio input / output device of the privacy application is allowed, which can ensure the reliability of the switching of the audio input / output device of the application and avoid conflicts between different rules. Optionally, clearing the input / output forced switching flag means setting the forced switching flag to false, indicating that the automatic selection of the audio input / output devices for the privacy application and the non-privacy application (including the case where there is no privacy application) has been completed. In this case, if Figure 3 The method shown can end. Thereafter, the audio input / output device of the application can be controlled based on other rules, and the audio input / output device of the application can be prevented from being used in conjunction with the audio input / output device of the application. Figure 3 The methods shown conflict.

[0057] The following takes answering a call on a mobile terminal as an example to describe how Figure 3 Application scenarios of the method shown.

[0058] When a wireless communication connection is established between the mobile terminal and the vehicle-mounted system, and music is played through the vehicle-mounted system, the mobile terminal receives an incoming call. During the call, the driver finds that the incoming call is very important and it is inconvenient to continue the call in the vehicle (i.e., he does not want the passengers to hear it). Therefore, the driver temporarily stops the car and leaves the vehicle. In this case, it will be detected that the mobile terminal leaves the vehicle. At the moment when the mobile terminal leaves the vehicle, the input and output preferred strategy is started, and optionally, the input and output forced switching flag is set to true. Then, a list of all applications currently running on the mobile terminal can be obtained, and one or more applications with audio input / output functions can be determined as target applications from the list of all applications obtained. Next, it can be determined whether there is a privacy application in the target application. In this example, the phone application is an application with an audio input function (the phone application also has an audio output function) and will be determined as a privacy application. At this time, since the input and output preferred strategy has been started, and optionally, the input and output forced switching flag has been set to true, and the phone application belongs to a privacy application, the mobile terminal can be automatically selected (i.e., switched) as the audio input / output device of the phone application. On the other hand, the music application is not a privacy application, so the vehicle system can be automatically selected (i.e., maintained) as the audio input / output device of the music application. In this way, on the one hand, the driver can answer the phone through the mobile terminal, and personal privacy can be protected. On the other hand, the passenger can enjoy music through the vehicle system, and the user experience can be guaranteed. In addition, after automatically selecting the mobile terminal as the audio input / output device of the phone application and / or selecting the vehicle system as the audio input / output device of the music application, the input and output forced switching flag can be set to false. When the driver returns to the vehicle, it will be detected that the mobile terminal has returned to the vehicle, and the input and output preference strategy can be turned off at this time. In this case, if the driver is still answering the phone, the vehicle system can be automatically selected as the audio input / output device of the phone application.

[0059] Figure 4 FIG. 1 is a flowchart showing another example of a method for automatically selecting an audio input / output device of an application on a mobile terminal according to a preset rule according to an embodiment of the present disclosure. Figure 4 The method shown can be used in Figure 3 The method shown is then executed, and can also be independent of Figure 3 In this embodiment, the preset event is that a new application on the mobile terminal is started after the mobile terminal leaves the vehicle while maintaining a wireless communication connection with the vehicle-mounted system.

[0060] Reference Figure 4In step S401, in response to the new application being an application with an audio input / output function, the setting state of the input / output preferred strategy is determined. As described above, when the mobile terminal leaves the vehicle while maintaining a wireless communication connection with the vehicle-mounted system, the input / output preferred strategy is activated, and the input / output preferred strategy remains in the on-board state when the mobile terminal does not disconnect the wireless communication connection with the vehicle-mounted system or does not return to the vehicle. Next, in step S402, in response to the input / output preferred strategy being activated, the audio input / output device of the new application is automatically selected based on the startup mode of the new application. In this way, after the driver leaves the vehicle with the mobile terminal, when the new application is started, the mobile terminal can be conveniently used as an audio input / output device without performing manual switching, thereby improving the convenience of the operation of the mobile terminal. According to an embodiment of the present disclosure, step S402 may specifically include: in response to the new application being started by the mobile terminal, the mobile terminal can be automatically selected as the audio input / output device of the new application; in response to the new application being started by the vehicle-mounted system, the vehicle-mounted system can be automatically selected as the audio input / output device of the new application. In this way, it is convenient for the driver to use the mobile terminal as an audio input / output device, and it is convenient for the passenger to use the vehicle-mounted system as an audio input / output device, thereby significantly improving the user experience.

[0061] As described above, when the mobile terminal leaves the vehicle while maintaining a wireless communication connection with the vehicle-mounted system, the input / output priority strategy can be activated, and when the mobile terminal disconnects the wireless communication connection with the vehicle-mounted system or returns to the vehicle, the input / output priority strategy can be deactivated. Figure 4 The method shown in Figure 3 When the method shown in the figure is executed later, when the audio input / output device of the privacy application is selected as the mobile terminal, or when the audio input / output device of the non-privacy application is selected as the vehicle system, the input / output forced switching flag can be cleared. Figure 4 The method shown is independent of Figure 3 In the case where the method shown is executed, when a new application is running in the mobile terminal, the input / output forced switching flag can be cleared. In this way, by starting / stopping the input / output preference strategy, it is possible to avoid automatic selection (or switching) of the audio input / output device of the application in unnecessary situations, thereby ensuring the reliability of automatic selection of the audio input / output device. On the other hand, by setting / clearing the input / output forced switching flag, it is possible to avoid automatic selection (or switching) of the audio input / output device of the application in unnecessary situations. Figure 3 The method shown and Figure 4 There is a conflict between the methods shown. That is, there is no need to determine whether the application is a privacy application.

[0062] The following describes how to receive a call after leaving the vehicle using the mobile terminal as an example. Figure 4 Application scenarios of the method shown.

[0063] When a wireless communication connection is established between the mobile terminal and the vehicle-mounted system, the driver temporarily stops the car and takes the mobile terminal away from the vehicle to go shopping, and the mobile terminal will be detected to have left the vehicle. At the moment when the mobile terminal is detected to have left the vehicle, the input-output preferred strategy can be activated, and optionally, the input-output forced switching flag can be cleared (i.e., the input-output forced switching flag is set to false). At this time, if the mobile terminal receives an incoming call and connects the incoming call, it will be determined whether the input-output preferred strategy is activated. If the mobile terminal always maintains a wireless communication connection with the vehicle-mounted system (i.e., the distance between the mobile terminal and the vehicle does not exceed the wireless communication distance, and the driver does not manually disconnect the wireless communication connection), the input-output preferred strategy always remains activated. When it is determined that the input-output preferred strategy has been activated, since the input-output forced switching flag is false and the phone application is started through the mobile terminal, the mobile terminal can be automatically selected as the audio input / output device of the phone application. On the other hand, if the passenger starts the music application (in the mobile terminal) through the vehicle-mounted system, since the input-output forced switching flag is false and the music application is started through the vehicle-mounted system, the vehicle-mounted system can be automatically selected as the audio input / output device of the music application. In this way, on the one hand, the driver can answer the phone through the mobile terminal, and personal privacy can be protected. On the other hand, the passengers can enjoy music through the in-vehicle system, and the user experience can be guaranteed. In addition, when the driver returns to the vehicle, it will be detected that the mobile terminal has returned to the vehicle, and the input and output priority strategy can be turned off. In this case, if the driver is still answering the phone, the in-vehicle system can be automatically selected as the audio input / output device of the phone application, that is, the audio input / output device of the phone application can be switched to the in-vehicle system.

[0064] Return to reference Figure 2 According to the embodiment of the present disclosure, the method for automatically selecting the audio input / output device of the application may also include the following steps. In step S203, in response to the mobile terminal returning to the vehicle while maintaining a wireless communication connection with the vehicle-mounted system, the vehicle-mounted system is automatically selected as the audio input / output device of the application on the mobile terminal, or in response to the mobile terminal disconnecting the wireless communication connection with the vehicle-mounted system, the mobile terminal is automatically selected as the audio input / output device of the application on the mobile terminal. In this way, on the one hand, driving safety can be ensured, and on the other hand, forced switching of the audio input / output device of the application can be achieved, thereby meeting the diverse requirements of users.
