In order to solve the above problems, the present application provides a method for forming a sound field of a specific sound effect for a fleet of vehicles, where there are at least two vehicles in the fleet, the method is applied to the vehicles in the fleet, as shown in fig. 1, fig. 1 is a flowchart of a method for forming a sound field of a specific sound effect for a fleet of vehicles, according to an exemplary embodiment of the present application, and the method includes steps S101-S103:

s101, acquiring the type of a vehicle loudspeaker and arrangement position information of the loudspeaker type corresponding to the vehicle;

in this step, the types of speakers carried on the vehicle and the positions of each speaker on the vehicle can be obtained. It can be understood that when the present solution is implemented, the speakers in a vehicle are not necessarily all enabled, and depending on the sound effect selected by the user, the position of the vehicle, and other factors, a vehicle may enable only some of the speakers, may enable all of the speakers, or may not enable any of the speakers.

S102, generating vehicle formation sound field azimuth information according to a sound effect mode selected by a user, wherein the vehicle formation sound field azimuth information represents reference positions of all loudspeakers started by the vehicle in a specified sound effect mode;

in this step, the user can specify the sound effect to be generated according to the preference of the user, the vehicle can acquire the vehicle formation sound field direction information required for forming the sound field of the sound effect, and the vehicle formation sound field direction information can include the reference position for installing the loudspeaker. Certainly, the sound field orientation information of the vehicle formation may further include the type, number, orientation, and the like of the speakers to be placed at each reference position, which is beneficial to determining how to place the speakers to form the information of the sound field with the corresponding sound effect, and a person skilled in the art may flexibly adjust the information included in the sound field orientation information of the vehicle formation according to actual situations.

According to an embodiment of the application, when the sound effect mode specified by the user is a dual-channel mode, the vehicle can acquire the position information of the vehicle formation sound field of the dual-channel mode, so that the situation that a left loudspeaker and a right loudspeaker are arranged side by side under the dual-channel mode is known. In this case, two vehicles in the vehicle group may be parked side by side, and then one speaker may be attached to the vicinity of each of the two vehicles, or a speaker provided on the vehicle may be used.

According to another embodiment of the application, when the audio mode specified by the user is the dolby panoramas with 5.1.4 sound channels, the vehicle can acquire the vehicle formation sound field azimuth information of the dolby panoramas with 5.1.4 sound channels, so that five full-frequency speakers with lower positions, four full-frequency speakers with higher positions and one woofer are needed in the dolby panoramas with 5.1.4 sound channels. In this case, five vehicles in the vehicle group may be parked at five vertices of the pentagon, and several speakers may be installed near each vehicle, or speakers may be used in the vehicle.

For convenience of description, the solution of the present application will be further explained and explained below based on the above-mentioned exemplary embodiment of the dolby panoramag with the 5.1.4 channel sound effect mode. It should be understood that the sound effect modes that can be realized by the present application are not limited to the two-channel mode and the dolby panoramic sound mode of 5.1.4 channels, which are listed in the above embodiments, and the above embodiments are not intended to limit the present application.

Dolby panoramas (Dolby Atmos) is a 3D surround sound technology developed by Dolby laboratories, and can combine with movie contents to present a dynamic sound effect; the sound effect from far to near can be more truly created; the loudspeaker box can be additionally arranged in cooperation with the ceiling, so that the sound field is surrounded, more sound details are displayed, and the viewing and listening feeling of audiences is improved. The conventional dolby panoramas have 5.1.4, 7.1.4, etc. modes, and in an indoor environment, the first number represents the number of full-range speakers placed on a horizontal plane (typically, at least 5 horizontal planes at the height of the ground or the ears in a sitting posture), the second number represents the number of woofers (typically, 1 or.2), and the last number represents the number of full-range speakers installed on the ceiling (at least two, typically, 2 or.4). In other words, in an indoor environment, the speakers required for a 5.1.4 channel dolby panorama sound include five full range speakers installed at the ear level of a person in a floor or sitting posture, one woofer, and four full range speakers installed at the ceiling.

According to one embodiment disclosed in the application, the speaker of an Acoustic Vehicle Alert System (AVAS System for short) on a Vehicle can be used to realize a dolby panoramic sound of 5.1.4 channels outdoors. The AVAS system disclosed by the application at least comprises a full-range loudspeaker arranged at the head of the vehicle, and also comprises a woofer arranged at the tail of the vehicle and a full-range loudspeaker arranged on the roof of the vehicle. As shown in fig. 2A, fig. 2A is a distribution diagram of speakers of an AVAS system according to an exemplary embodiment of the present application. Specifically, one full-range speaker installed in the vehicle head in the AVAS system may be used as the dolby panoramas with 5.1.4 channels, one of which is installed on the ground or at the ear height in a sitting posture; using a woofer arranged at the tail of the vehicle and arranged at the head of the vehicle in the AVAS system; in the AVAS system, one full-range speaker installed on the roof is used as one of the full-range speakers installed on the ceiling in the dolby panoramas of 5.1.4 channels. Of course, according to another embodiment disclosed in the present application, other speakers other than AVAS, such as automobile accessories and portable audio, may be used to form a dolby panorama sound with 5.1.4 channels outdoors, which is not limited in the present application.

When the method provided by the application is practically applied, the sound field orientation information of the vehicle formation can be determined through various means, and the reference position of the loudspeaker can also be determined through various ways. For example, in one example, the sound field direction information of the formation of vehicles may be that each vehicle automatically generates the sound field direction information of the corresponding formation of vehicles through a preset algorithm according to a specified sound effect mode, and in another example, one of the vehicles may be used as a leading vehicle, and the leading vehicle generates the sound field direction information of the formation of vehicles according to the specified sound effect mode and then distributes the sound field direction information to other vehicles of the fleet.

It is worth pointing out that, because the scheme of the application is based on the sound field of the specific sound effect formed by the motorcade, it can be understood that if the vehicles are not synchronized, the problems that the audio played by the vehicles is not synchronized, even the audio played is not consistent, and the like are easily caused, and the user experience is influenced. Further, in determining the reference position of the speaker, since the outdoor space is wide, even if the mutual positional relationship between the vehicles is determined, it is not convenient to determine the specific position of the vehicle in the space.

Therefore, according to one embodiment disclosed by the application, the vehicles are more conveniently synchronized by setting the main guide vehicle, and the sound field and direction information of vehicle formation can be more conveniently determined. The following details the implementation process for the above step S102 by taking an embodiment in which the fleet distinguishes between the leading vehicle and the non-leading vehicle as an example:

s1021, connection is established;

since the embodiment needs to use the leading vehicle to communicate with other non-leading vehicles, in this step, the vehicles in the fleet can establish connection through bluetooth, lan, etc. when the user selects the audio mode. As is well known to those skilled in the art, the connection establishment method is not limited to bluetooth or lan, and the application does not limit the specific connection method.

In this embodiment, the non-master vehicles in the fleet may only establish connection with the master vehicle, and the non-master vehicles may or may not establish connection with each other. The lead vehicle may then uniformly control the remaining vehicles based on this connection.

In other embodiments, if the lead vehicle is not present, the vehicles in the fleet may obtain the messages received by the other vehicles in real time based on the connection.

According to some embodiments disclosed in the present application, the vehicle may monitor the remaining energy of the vehicle, such as the electric quantity of the electric car, the fuel quantity of the fuel car, and the like, and obtain the remaining mileage that the vehicle can travel; the position of the charging point closest to the current position, such as the position of the closest charging pile and the position of the closest gas station, can also be obtained, the distance between the current position of the vehicle and the closest charging point is calculated, and the client is reminded before the fact that the residual energy of the vehicle is insufficient to drive to the closest charging point is judged, so that the trouble of the client caused by the problems of insufficient electric quantity, insufficient fuel and the like is avoided.

S1022, determining the reference position of the loudspeaker according to the sound field azimuth information of the vehicle formation;

in this step, the vehicle may determine the reference position of the speaker according to the sound field orientation information of the vehicle formation, and those skilled in the art know that there are many methods for determining the reference position of the speaker according to the sound field orientation information of the vehicle formation. For example, if the host vehicle is a leading vehicle, for a non-leading vehicle, the leading vehicle may acquire sound field orientation information of a formation of vehicles according to the sound effect mode and determine a reference position of a speaker, and then send the reference position to the non-leading vehicle; if the host vehicle is a non-leading vehicle, one of the reference positions is obtained from the leading vehicle.

In addition, the leading vehicle can also acquire the sound field azimuth information of the vehicle formation according to the sound effect mode and send the sound field azimuth information of the vehicle formation to the non-leading vehicle, and the non-leading vehicle respectively determines the reference position; the sound effect mode can also be shared in real time, and the vehicles in the fleet respectively determine the speaker reference position according to the sound effect mode. The specific method for determining the reference position of the loudspeaker according to the sound field orientation information of the vehicle formation is not limited in the application.

It will be appreciated by those skilled in the art that for the speakers of the AVAS system, the vehicle may control the turning on or off of one or more of the speakers, rather than merely enabling them to be turned on or off simultaneously; for the speakers of non-AVAS systems such as external speakers, the same effect can be achieved by controlling one or more speakers not to be connected with the vehicle. Therefore, according to one embodiment disclosed in the present application, in general, the vehicle only needs to be parked at any one of the reference positions, and there is no need to establish a one-to-one correspondence relationship between the vehicle and the reference positions.

S1023, stopping the vehicle to reference positions respectively;

in the step, the leading vehicle can stop the leading vehicle and other vehicles in the motorcade to the reference position based on the automatic driving technology; the vehicles in the fleet may also be parked to the reference location by other methods such as manual parking by the user, and the method of parking the vehicles to the reference location is not limited in the present application.

To further illustrate the above steps S1021-S1023, according to an embodiment of the present disclosure, the specified acoustics mode is a dolby panound of 5.1.4 channels, but there are less than five vehicles in the fleet that have AVAS systems installed, and one of the vehicles may be determined as a leading vehicle and the reference position of the speaker may be determined. Then, the vehicles in the fleet can be stopped at part of the reference positions, and the external speakers and other devices are installed at the rest of the reference positions, so as to form a sound field with a dolby panoramic sound of 5.1.4.

According to another embodiment disclosed in the present application, a dolby panorama sound with an audio mode of 5.1.4 channels can be formed based on the AVAS system only. At the moment, a full-frequency loudspeaker arranged on the head of the AVAS system on five vehicles is used as a full-frequency loudspeaker arranged on the ground or at the ear height of a person in a sitting posture required by the sound effect mode; a woofer arranged at the tail of the vehicle and arranged at the head of the vehicle in the AVAS system of any vehicle; one full-range speaker mounted on the roof of any four-car AVAS system is used as the ceiling-mounted full-range speaker required for the prominence mode. In other words, to form a dolby panorama sound of 5.1.4 channels based on only the speakers of the AVAS system, the fleet would need to have at least five vehicles with the AVAS system installed.

According to still another embodiment disclosed by the application, the specified sound effect mode is a dolby panoramic sound with 5.1.4 sound channels, the AVAS system is installed in only five vehicles in the fleet, one vehicle can be determined as a leading vehicle, the position information of the sound field of the vehicle formation in the specified sound effect mode is generated, and the reference position of the loudspeaker is determined according to the position information of the sound field of the vehicle formation. Specifically, when the acoustics mode is a dolby pansonian of 5.1.4 channels, the reference positions of the speakers may be determined as five vertices of a pentagon.

According to another embodiment of the present disclosure, the specified acoustics mode is a dolby pansonics with 5.1.4 channels, and there are more than five vehicles in the fleet that have AVAS systems installed. Optionally, five of the vehicles may implement the above-mentioned "exactly five vehicles have AVAS systems installed" scheme, and the remaining vehicles do not participate in forming the dolby panophony of 5.1.4 channels; one vehicle can be taken as a leading vehicle, five alternative vehicles can be taken as non-leading vehicles, the leading vehicle determines the reference position of the loudspeaker according to the position information of the formation sound field of the vehicles, and only loudspeaker devices such as the loudspeaker and the external loudspeaker on the non-leading vehicles participate in forming the Dolby panoramic sound of 5.1.4 sound channels.

On the other hand, according to one embodiment disclosed herein, the reference position of the speaker may be determined based on the current position of the lead vehicle; the distance between the reference locations may also be determined based on factors such as the surrounding environment, the number of users, etc. Still taking the dolby panorama with 5.1.4 sound channels as an example, the current position of the leading vehicle or a position near the leading vehicle can be determined as a vertex of a pentagon, and the side length of the pentagon and the positions of other four vertices are determined according to the number of users, the area size of a place which can be used for parking nearby and other factors, so as to obtain the pentagon with a proper size. Therefore, the scheme disclosed by the application can stop the vehicle to a proper position, reserve enough activity space for a user, and can also reduce the distance for stopping the vehicle in the fleet to the reference position as much as possible.

It should be noted that the speaker used in the solution disclosed in the present application may be a speaker of an AVAS system, or may be a speaker of a non-AVAS system such as an external speaker; the scheme disclosed by the application also does not limit the specific sound effect mode, for example, the sound effect mode can be a two-channel mode, a dolby panoramic sound mode of 5.1.4, and other sound effect modes such as 7.1.4; when the solution disclosed in the present application is implemented, any vehicle in the fleet may not be set as the leading vehicle, and the foregoing embodiments should not be considered as limitations of the present application.

S103, adjusting the loudspeakers based on the distance between the current vehicle and other vehicles of the fleet and the distance between the current vehicle and the center of the preset area so as to form a sound field with a specified sound effect mode in the preset area.

In the step, the vehicles in the fleet can acquire the distances between the vehicles and other vehicles and the distance between the vehicles and the center of the preset area through the radar equidistant detector, and if the main vehicle exists, the non-main vehicle can send the acquired distances to the main vehicle.

The angle between each speaker may then be determined based on the distance between the own vehicle and the other vehicles in the fleet, and the distance of the own vehicle to the center of the preset area, adjusting the volume of the enabled speakers on the vehicle. At the moment, the enabled loudspeaker of the vehicle and the loudspeakers of other vehicles in the motorcade can be controlled to play the same audio, and the user can listen to the audio with the specified sound effect in the preset area, so that the requirements of the user on listening to songs, watching videos, singing and the like outdoors are met.

In addition, because the use scene of the scheme disclosed in the present application is usually outdoors, and provides convenience for the user, according to an embodiment disclosed in the present application, the surrounding mosquitoes can be driven away by playing one or more specific audios before playing the audio specified by the user.

The above step S103 is further explained below by taking the dolby panoramag of 5.1.4 channels as an example. The leading vehicle can adjust the volume of the loudspeaker of each vehicle on the reference position through a software algorithm capable of realizing panoramic sound based on the distance between every two vehicles in the fleet and the distance from each vehicle to the center of the preset area. Therefore, the scheme disclosed by the application does not specifically limit the enabled loudspeaker of each vehicle, and only the vehicles participating in forming the specified sound effect mode are ensured to integrally meet the requirement that the enabled loudspeaker meets the corresponding sound effect mode. And adjusting the loudspeaker according to the software algorithm to form a sound field with a specific sound effect mode. Illustratively, when the acoustics mode is a dolby panound of 5.1.4 channels, each vehicle-enabled speaker may be as shown in fig. 2B, or as shown in fig. 2C, and it will be understood by those skilled in the art that fig. 2B and 2C are only exemplary of scenes in which a 5.1.4 channel dolby panound is formed based on an AVAS system only when the fleet includes exactly five vehicles with the AVAS system installed; in addition, only the speakers needed to form the dolby panoramas of 5.1.4 channels are shown in fig. 2B and 2C, and any vehicle in the platoon may contain other speakers not shown, and the illustration in the drawings should not be considered as limiting the present application.

On the other hand, according to an embodiment of the present disclosure, when the sound effect mode is a dolby panorama sound of 5.1.4 channels, the preset area may be a central area of a pentagon enclosed by the vehicle. Of course, a person skilled in the art may flexibly set the position of the preset region according to an actual situation, and as an example, the present application further provides a method for determining the preset region, which specifically includes the following steps S1031 to S1032:

s1031, identifying the position of the user through the camera, and setting the position of the user as a preset area;

in this step, the vehicle can recognize the position of the user through the camera and set a preset area. It is understood that the camera used in this step is not limited to the camera of the current vehicle itself, but may be the camera of other vehicles in the fleet. In addition, a plurality of users are generally included in an application scenario of the scheme of the present application, according to an embodiment disclosed in the present application, a region where users are most dense may be set as a preset region, and other positions may also be set as preset regions based on factors such as selection of the users, and a method for setting the preset region may be flexibly selected by a person skilled in the art according to an actual situation.

S1032, when the change of the user position is detected, whether the position of the preset area is changed or not is judged.

In this step, when it is detected that the position of the user changes, it may be determined whether the position of the preset area needs to be changed synchronously.

As described above, the application scenario of the scheme of the present application generally includes a plurality of users, and if a change in the position of any one user is detected and the position of the preset area is changed immediately, the preset area is easily changed frequently, so that the user experience is not good. Therefore, according to an embodiment disclosed in the present application, the user may be queried when detecting that the user position changes, and whether the position of the preset area needs to be changed is determined based on the selection of the user, and whether the preset area is fixed at the current position may also be determined after the first query, thereby avoiding frequent queries to the user. Of course, those skilled in the art can flexibly make the judgment standard according to the actual situation, and the application is not limited.

The application discloses a method for forming a sound field of a specific sound effect by a fleet of vehicles, which can determine reference positions of loudspeakers on the vehicles according to position information of a vehicle formation sound field, and stop the vehicles at the reference positions, wherein the position information of the vehicle formation sound field at least represents the reference positions of all the loudspeakers which are activated in a specified sound effect mode. Therefore, a user only needs to stop the vehicle to a specified place and control the vehicle to start the corresponding loudspeaker, or the loudspeaker needing to be started is externally connected to the vicinity of the vehicle, the loudspeaker does not need to be manually installed at a specified reference position, and the use of the user can be facilitated. The loudspeakers may then be adjusted based on the distance between any vehicle in the fleet of vehicles and other vehicles in the fleet of vehicles, and the distance between the vehicle and the center of the predetermined area, to form a sound field with the specified prominence mode in the predetermined area. And the position of the preset area can be set based on various factors such as the selection of the user, and the use of the user is facilitated.
