The above exemplary steps of the embodiments of the present application will be described below.
In step S101, a plurality of target sound sources to be played during the running of the vehicle are obtained, where the plurality of target sound sources include two types of sound sources, namely entertainment type and non-entertainment type.
Here, during the driving of the vehicle, the vehicle control platform receives a plurality of target sound sources to be played, and the plurality of target sound sources may be entertainment applications (App), such as: music software, video software, game software, radio software, etc., or non-entertainment applications such as: system software, navigation software, etc., and the types of entertainment applications and non-entertainment applications are not limited herein.
In step S102, a driving environment of a current vehicle is detected, and a first sound source playing mode matching the driving environment is determined; the first sound source playing mode comprises a first playing mode and a second playing mode, the first playing mode simultaneously plays a plurality of target sound sources through the first equipment and the second equipment, and the second playing mode plays the target sound sources of entertainment and non-entertainment through the first equipment.
In some embodiments, the driving environment of the vehicle includes a current vehicle speed of the vehicle and a risk level of a current driving road section of the vehicle, and the current vehicle speed of the vehicle and/or the risk level of the current driving road section of the vehicle are/is detected to obtain two driving environments, wherein one driving environment is "the playing effect of the non-entertainment target sound source does not need to be improved", and the other driving environment is "the playing effect of the non-entertainment target sound source needs to be improved", and under the two driving environments, the two driving environments are respectively matched with a first playing mode and a second playing mode in a first sound source playing mode, and under the driving environment "the playing effect of the non-entertainment target sound source does not need to be improved", the first playing mode is matched, namely a traditional sound mixing playing mode, and a plurality of target sound sources are played simultaneously through a first device and a second device; and matching the second play mode under the driving environment that the play effect of the non-entertainment target sound source needs to be improved, and playing the entertainment target sound source through the first equipment and playing the non-entertainment target sound source through the second equipment.
In some embodiments, the first device may be an audio playback device near a non-driver seat, such as a car stereo near the non-driver seat, the non-driver seat may be a front seat or a rear seat, and the second device may be an audio playback device near a driver seat, such as a car stereo near the driver seat.
In some embodiments, referring to fig. 2, fig. 2 is a schematic flowchart of steps S201 to S203 provided in an embodiment of the present application, and step S102 shown in fig. 1 may be implemented by steps S201 to S203, which will be described with reference to the steps.
In step S201, the current vehicle speed of the vehicle is acquired.
Here, the current vehicle speed of the vehicle may be acquired through the vehicle control platform.
In step S202, when the current vehicle speed is less than or equal to the preset vehicle speed threshold, the current play mode is determined as the first play mode.
In some embodiments, the current vehicle speed of the vehicle acquired through the vehicle control platform is compared with a preset vehicle speed threshold, and when the current vehicle speed of the vehicle is less than or equal to the preset vehicle speed threshold, the play mode may be adjusted to the first play mode.
As an example, the preset vehicle speed threshold may be 60 km/h, generally, the lowest speed of a highway is 60 km/h as the vehicle speed threshold, the vehicle speed is lower than 60 km/h to indicate low speed, the vehicle speed is higher than 60 km/h to indicate high speed, and when the vehicle speed is lower than 60 km/h, the vehicle speed is considered to be lower at this time, and the driving environment is safer.
In step S203, when the current vehicle speed is greater than the vehicle speed threshold, the current playback mode is determined to be the second playback mode.
As an example, when the vehicle speed is higher than 60 km/h, it is considered that the vehicle speed is high at this time, the driving environment is not safe, and the driver needs to increase attention, and the conventional mixed sound playing mode may cause the driver to hear the navigation voice or the system voice, so that the current playing mode is determined to be the second playing mode, that is, the target sound source of the entertainment category is played through the first device and the target sound source of the non-entertainment category is played through the second device.
In the above manner, by detecting the current vehicle speed and comparing the current vehicle speed with the preset vehicle speed threshold, when the vehicle speed is low, the first playing mode, that is, the traditional sound mixing playing mode, is adopted to play a plurality of target sound sources; when the vehicle speed is higher, the second playing mode is adopted, the audio playing device close to the driving seat, such as the vehicle-mounted sound box close to the driving seat, is used for playing the non-entertainment target sound source, and the audio playing device close to the non-driving seat, such as the audio playing device of the assistant driving seat and the audio playing device of the back seat, is used for playing the entertainment target sound source, so that a more excellent playing strategy is provided, the listening effect of the non-entertainment target sound source is improved, and the driving safety is guaranteed.
In some embodiments, referring to fig. 3, fig. 3 is a schematic flowchart of steps S301 to S303 provided in an embodiment of the present application, and step S102 shown in fig. 1 may be implemented by steps S301 to S303, which will be described with reference to the steps.
In step S301, a risk level of a current travel section of the vehicle is acquired.
Here, the risk level of the current travel section of the vehicle may be acquired through the navigation class application.
In step S302, when the risk level of the current driving road segment is less than or equal to the preset safety threshold, it is determined that the current play mode is the first play mode.
In some embodiments, the safety threshold may be matched with a risk threshold of the navigation application for detecting the road segment, when the current road is a place with a high accident rate, the risk threshold is considered to be exceeded, when the current road is a place with a low accident rate, the risk threshold is considered not to be exceeded, for example, a driving route is navigated by the navigation application, when the current road is driven to a certain road segment, the navigation application detects that the current road is a place with a low accident rate, and when the current road is considered not to exceed the risk threshold, the current playing mode is determined to be the first playing mode, that is, the conventional remix playing mode.
In step S303, when the risk level of the current travel section is greater than the safety threshold, it is determined that the current play mode is the second play mode.
In some embodiments, the driving route is navigated by the navigation application, when the driver travels to a certain road section, the navigation application detects that the current road is a place with a high accident occurrence, and the navigation application sends out a voice prompt that "the current road is a place with a high accident occurrence and please drive carefully", at this time, it is considered that a risk threshold is exceeded, and the conventional mixing playback mode may cause the driver to hear the navigation voice or the system voice, so that it is determined that the current playback mode is the second playback mode, that is, the entertainment type target sound source is played by the first device and the non-entertainment type target sound source is played by the second device.
In the above manner, by detecting the risk level of the current driving road section and comparing the risk level with the preset safety threshold, when the current driving road section is an accident low-occurrence place, the first playing mode, that is, the traditional sound mixing playing mode is adopted to play a plurality of target sound sources; when the current driving road section is an accident high-occurrence place, the second playing mode is adopted, the non-entertainment target sound source is played through the audio playing device close to the driving seat, such as a vehicle-mounted sound box close to the driving seat, and the entertainment target sound source is played through the audio playing device close to the non-driving seat, such as a copilot and the audio playing device of a back-row seat, so that a more optimal playing strategy is provided, the listening effect of the non-entertainment target sound source is improved, and the driving safety is guaranteed.
In step S103, the current play mode is adjusted to be the first play mode or the second play mode matching with the driving environment, and the multiple target sound sources are played through the adjusted first play mode or the second play mode.
Here, after the driving environment "the playing effect of the non-entertainment type target sound source does not need to be improved" or the driving environment "the playing effect of the non-entertainment type target sound source needs to be improved" is acquired, the first sound source playing mode may be adjusted to be the mode matched with the driving environment or the second playing mode, and the plurality of target sound sources are played through the adjusted first playing mode or the second playing mode.
In some embodiments, referring to fig. 4, fig. 4 is a schematic flowchart of steps S401 to S402 provided in the embodiments of the present application, and after determining the first audio source playing mode matching with the driving environment, steps S401 to S402 may be further executed, which will be described with reference to the steps.
In step S401, when the first audio source playback mode is the first playback mode and the second device fails, the volume of the first device is increased to the first volume threshold.
In some embodiments, when the play mode is the first play mode, that is, the conventional mixing play mode, and the audio playing device near the driving seat fails, in order to enable the driving seat to still hear the multiple target sound sources, the volume of the audio playing device near the non-driving seat may be increased to the first volume threshold.
For example, in the first play mode, the audio play device near the driving seat and the audio play device near the non-driving seat both play the multiple target sound sources at 50% of volume, and if the audio play device near the driving seat fails to play the sound normally, in order to allow the driver in the driving seat to still hear the multiple target sound sources, the volume of the audio play device near the non-driving seat may be increased to a first volume threshold, for example, the volume of the audio play device near the co-driving seat may be increased to 60%.
By the mode, when the audio playing equipment close to the driving seat fails in the first playing mode, the audio receiving effect of the driving seat can be preferentially guaranteed through the playing equipment close to the non-driving seat, so that a driver can hear a non-entertainment target sound source, and driving safety is guaranteed.
In step S402, when the first sound source playing mode is the second playing mode, if the second device fails, the first sound source playing mode is adjusted to be the third playing mode, wherein the third playing mode plays the non-entertainment target sound source through the first device.
In some embodiments, when the playing mode is the second playing mode, and the audio playing device near the driving seat fails, in order to enable the driving seat to still hear the non-entertainment target sound source, the non-entertainment target sound source may be played through the audio playing device near the non-driving seat, that is, the third playing mode.
For example, in the second play mode, the audio player near the driving seat plays the non-entertainment target sound source, and the audio player near the non-driving seat plays the entertainment target sound source, and if the audio player near the driving seat fails to play the sound normally, the audio player near the non-driving seat may stop playing the entertainment target sound source and play the non-entertainment target sound source through the audio player near the non-driving seat in order to make the driver of the driving seat still hear the non-entertainment target sound source.
In the mode, when the audio playing device close to the driving position fails in the second playing mode, the playing device close to the non-driving position preferentially ensures that the driving position can receive the non-entertainment target sound source, so that the driver can hear the non-entertainment target sound source, and driving safety is ensured.
In some embodiments, referring to fig. 5, fig. 5 is a schematic flowchart of steps S501 to S502 provided in the embodiments of the present application, and will be described with reference to the steps.
In step S501, when the first sound source playing mode is the second playing mode, if the first device and the second device are in the speaker mode, the volume of the first device is adjusted to a second volume threshold and the volume of the second device is adjusted to a third volume threshold according to a first distance from the first device to the driving seat and a second distance from the second device to the driving seat, respectively, where the volume of the second volume threshold attenuated by the first distance is smaller than or equal to the volume of the third volume threshold attenuated by the second distance.
In some embodiments, the first sound source playing mode is the second playing mode, that is, the audio playing device close to the driving seat plays the target sound source of the non-entertainment type, and the audio playing device close to the non-driving seat plays the target sound source of the entertainment type, and if the audio playing device close to the driving seat and the audio playing device close to the non-driving seat are both in the speaker mode (play-out mode), in order to ensure that the volume of the target sound source of the non-entertainment type acquired by the driving seat is greater than the volume of the target sound source of the entertainment type acquired by the driving seat, the volume of the audio playing device close to the driving seat may be adjusted to the third volume threshold according to the distance between the audio playing device close to the driving seat and the distance between the audio playing device close to the non-driving seat and the driving seat, and the volume of the audio playing device close to the non-driving seat may be attenuated in the process of sound propagation, and the volume of the third volume threshold after the attenuation of the second distance is greater than the volume threshold after the first distance, so as to ensure that the volume of the target sound source of the audio playing device close to the driving seat is greater than the volume of the target sound source of the entertainment type acquired by the driving seat.
As an example, if the volume of the target sound source of the entertainment type played by the first device is 80%, the volume of the target sound source of the non-entertainment type played by the second device is 60%, the volume attenuation amount of the first device over the first distance is 20%, and the volume attenuation amount of the second device over the second distance is 10%, at this time, the volume of the target sound source of the entertainment type received by the pilot is 60%, the volume of the target sound source of the non-entertainment type received by the pilot is 50%, the volume of the target sound source of the entertainment type received by the pilot is greater than the volume of the target sound source of the non-entertainment type, and at this time, the volumes of the target sound source of the entertainment type received by the pilot should be adjusted according to the distances from the first device and the second device to the pilot respectively, so that the volume of the first device is adjusted to be 70%, the volume of the second device is adjusted to be 60%, and after the adjustment, the volume of the target sound source of the entertainment type received by the pilot is equal to the volume of the target sound source of the non-entertainment type, and is 50% both. The above-mentioned adjusting method is to fix the volume of the second device and adjust the volume of the first device, and in order not to adjust the volume of the audio playing device near the driving side as much as possible, the volume of the first device may also be fixed and the volume of the second device may also be adjusted, and both the volumes of the first device and the second device may also be adjusted.
In the mode, the volumes of the first device and the second device are adjusted according to the first distance from the first device to the driving position and the second distance from the second device to the driving position, and after the adjusted volumes are transmitted, the volumes of the non-entertainment target sound sources received by the driving position side are not less than the volumes of the entertainment target sound sources, so that the driving safety is ensured.
In step S502, if the first device is in the earpiece mode, the volume of the first device is adjusted in response to the volume adjustment request of the first device.
In some embodiments, when the first audio source playing mode is the second playing mode and the first device is in the earphone mode, it is determined that the volume of the first device does not affect the driving side to receive the audio generated by the second device, and the volume of the first device can be adjusted by itself.
As an example, the first device is an audio playing device of a rear seat, such as an audio and video system embedded in the back of a front seat, and the audio and video system provides a headphone jack, in this case, when the first device is plugged into a headphone to change to an earphone mode, the audio of the first device is transmitted through the headphone, and the volume of the first device does not affect the driver's seat side to receive the audio played by the second device.
