[0034] It is to be understood that, although the terms first, second, third, etc. can be used herein to describe various information, the information should not be limited to these terms. These terms are only used to differentiate one piece of information from another. For example, a first information can also be termed a second information, similarly, a second information can also be termed a first information, without departing from the scope of the present application. Depending on the context, the word "if' as used herein can be interpreted as meaning "when" or "in response to determining".

[0035] Next, the embodiments of the present application are described in detail.

[0036] In the process of a vehicle group going camping, if a user wants to enjoy music outdoors, he usually enjoys music in his own vehicle. After leaving the vehicle, although he can use a loudspeaker device to play music, he cannot be provided with sufficient immersion, which affects his auditory experience.

[0037] To solve the above problem, the present application provides a method for a vehicle group to form a sound field with a specific sound effect. The vehicle group has at least two vehicles. The method is applied to the vehicles in the vehicle group, as shown in Figure 1 Figure 1 is a flowchart of a method for a vehicle group to form a sound field with a specific sound effect according to an exemplary embodiment of the present application, which includes steps S101-S103:

[0038] S101, obtaining vehicle loudspeaker types and loudspeaker type corresponding arrangement position information on the vehicle;

[0039] In this step, the types of loudspeakers carried by the vehicle and the positions of each loudspeaker on the vehicle can be obtained. It can be understood that when implementing the present solution, the loudspeakers on a vehicle are not necessarily all enabled. According to the user-selected sound effect, the position of the vehicle, and other factors, a vehicle can only enable part of the loudspeakers, can enable all the loudspeakers, or can not enable any loudspeaker.

[0040] S102, generating vehicle formation sound field orientation information according to a user-selected sound effect mode, wherein the vehicle formation sound field orientation information represents the reference positions of the loudspeakers enabled by the vehicle in the specified sound effect mode;

[0041] ​In this step, the user can specify the sound effect he wants to generate according to his own preferences, and the vehicle can obtain the vehicle formation sound field orientation information required to form the sound field of the sound effect. The vehicle formation sound field orientation information can include the reference position of the installed loudspeaker. Of course, the vehicle formation sound field orientation information can also include the type, number, orientation, and other information that is conducive to determining how to place the loudspeaker to form a sound field with the corresponding sound effect. Those skilled in the art can flexibly adjust the information included in the vehicle formation sound field orientation information according to the actual situation.

[0042] According to an embodiment of the present application, when the user specifies a two-channel sound effect mode, the vehicle can obtain two-channel mode vehicle formation sound field orientation information to learn that in two-channel mode, one left and one right side-by-side placed loudspeaker is required. At this time, the two vehicles in the vehicle formation can be parked side by side, and then one loudspeaker can be installed near each of the two vehicles, or the self-equipped loudspeaker on the vehicle can be used.

[0043] According to another embodiment of the present application, when the user specifies a 5.1.4 channel Dolby Atmos sound effect mode, the vehicle can obtain 5.1.4 channel Dolby Atmos vehicle formation sound field orientation information to learn that in 5.1.4 channel Dolby Atmos mode, five low-position full-frequency loudspeakers, four high-position full-frequency loudspeakers, and one subwoofer are required. At this time, the five vehicles in the vehicle formation can be parked at the five vertices of a pentagon, and a plurality of loudspeakers can be installed near each vehicle, or the self-equipped loudspeaker on the vehicle can be used.

[0044] For convenience of description, the following further explains and describes the scheme of the present application based on the above embodiment of the 5.1.4 channel Dolby Atmos sound effect mode. It should be understood that the sound effect mode that can be achieved by the present application is not limited to the above-mentioned two-channel mode and 5.1.4 channel Dolby Atmos mode, and the above-mentioned embodiments cannot be used to limit the present application.

[0045] Dolby Atmos is a 3D surround sound technology developed by Dolby Laboratories, which can present dynamic sound effects in combination with film content, create more realistic sound effects from far to near, and cooperate with ceiling-mounted speakers to achieve sound field surround and show more sound details, thus improving the audience's viewing and listening experience. Common Dolby Atmos has modes such as 5.1.4 and 7.1.4. In an indoor environment, the first number represents the number of full-range speakers placed on a horizontal plane (usually the ground or the horizontal plane at the height of the human ear in a sitting position, at least 5), the second number represents the number of subwoofers (usually.1 or.2), and the last number represents the number of full-range speakers installed on the ceiling (at least two, usually.2 or.4). In other words, in an indoor environment, the 5.1.4 channel Dolby Atmos requires five full-range speakers installed on the ground or at the height of the human ear in a sitting position, one subwoofer, and four full-range speakers installed on the ceiling.

[0046] According to one embodiment of the present application, the 5.1.4 channel Dolby Atmos can be realized outdoors using the speakers of the Acoustic Vehicle Alert System (abbreviated as AVAS system) on the vehicle. The AVAS system disclosed in the present application at least includes one full-range speaker installed on the front of the vehicle, and can further include one subwoofer installed on the rear of the vehicle and one full-range speaker installed on the roof of the vehicle. As shown in Figure 2A Figure 2A is a distribution diagram of the speakers of an AVAS system according to an exemplary embodiment of the present application. Specifically, one full-range speaker installed on the front of the AVAS system can be used as one of the full-range speakers installed on the ground or at the height of the human ear in a sitting position in the 5.1.4 channel Dolby Atmos; one subwoofer installed on the rear of the AVAS system can be used; and one full-range speaker installed on the roof of the AVAS system can be used as one of the full-range speakers installed on the ceiling in the 5.1.4 channel Dolby Atmos. Of course, according to another embodiment of the present application, other non-AVAS speakers such as car accessories and portable speakers can also be used to form the 5.1.4 channel Dolby Atmos outdoors, which is not limited by the present application.

[0047] ​In practical applications of the method provided in the application, the vehicle formation sound field orientation information can be determined by various means, and the reference position of the loudspeaker can be determined by various ways. For example, in one example, the vehicle formation sound field orientation information can be automatically generated by each vehicle according to a specified sound effect mode through a preset algorithm, and in another example, one of the vehicles can be used as a leading vehicle, and the vehicle formation sound field orientation information can be generated by the leading vehicle according to a specified sound effect mode and then distributed to other vehicles in the vehicle formation.

[0048] It is worth pointing out that, since the scheme of the application is based on the formation of a specific sound field by a vehicle formation, it can be understood that if the vehicles are not synchronized, it is easy to cause the audio played by each vehicle to be out of synchronization, or even inconsistent, which will affect the user experience. In addition, when determining the reference position of the loudspeaker, since the outdoor space is open, even if the relative positional relationship between the vehicles is determined, it is not convenient to determine the specific position of the vehicles in the space.

[0049] Therefore, according to one embodiment disclosed in the application, the leading vehicle is set to make it more convenient to synchronize the vehicles, and it is also convenient to determine the vehicle formation sound field orientation information. The implementation process of step S102 is described in detail below with the example of an embodiment in which the vehicle formation is divided into a leading vehicle and non-leading vehicles:

[0050] S1021, establishing a connection;

[0051] Since this embodiment needs to use the leading vehicle to communicate with other non-leading vehicles, in this step, the vehicles in the vehicle formation can establish a connection through Bluetooth, a local area network, or the like when the user selects a sound effect mode. It is well known to those skilled in the art that the connection establishment method is not limited to Bluetooth and a local area network, and the specific connection method is not limited in the application.

[0052] In this embodiment, the non-leading vehicles in the vehicle formation can only establish a connection with the leading vehicle, and the non-leading vehicles can establish a connection or not. Then the leading vehicle can uniformly control the remaining vehicles based on the connection.

[0053] In other embodiments, if there is no leading vehicle, the vehicles in the vehicle formation can obtain the messages received by other vehicles in real time based on the connection.

[0054] According to some embodiments disclosed in the present application, the vehicle can monitor the remaining energy of itself, such as the power of an electric vehicle, the fuel of a fuel vehicle, etc., and obtain the remaining mileage that the vehicle can travel; the position of the nearest energy supply point, such as the position of the nearest charging pile, the position of the nearest gas station, etc., can also be obtained, and the distance between the current position of the vehicle and the nearest energy supply point can be calculated, and the client can be reminded before it is judged that the remaining energy of the vehicle is insufficient to travel to the nearest energy supply point, so as to avoid the problem of insufficient power, insufficient fuel, etc. causing trouble to the client.

[0055] S1022, determining the reference position of the loudspeaker according to the vehicle platoon sound field direction information;

[0056] In this step, the vehicle can determine the reference position of the loudspeaker according to the vehicle platoon sound field direction information. Those skilled in the art are familiar with the method of determining the reference position of the loudspeaker according to the vehicle platoon sound field direction information. For example, if the vehicle is a leading vehicle, the leading vehicle can obtain the vehicle platoon sound field direction information according to the sound effect mode and determine the reference position of the loudspeaker, and then send the reference position to the non-leading vehicle. If the vehicle is a non-leading vehicle, the non-leading vehicle can obtain one of the reference positions from the leading vehicle.

[0057] In addition, the leading vehicle can obtain the vehicle platoon sound field direction information according to the sound effect mode and send the vehicle platoon sound field direction information to the non-leading vehicle, and the non-leading vehicle can determine the reference position respectively. The sound effect mode can also be shared in real time, and each vehicle in the vehicle platoon can determine the reference position of the loudspeaker according to the sound effect mode. The present application does not limit the specific method of determining the reference position of the loudspeaker according to the vehicle platoon sound field direction information.

[0058] Those skilled in the art can understand that for the loudspeakers of the AVAS system, the vehicle can control the opening or closing of one or more loudspeakers, instead of only enabling them to start or close at the same time; for the external loudspeakers and other loudspeakers of the non-AVAS system, it is only necessary to control one or more loudspeakers to be disconnected from the vehicle to achieve the same effect. Therefore, according to one embodiment disclosed in the present application, in general, it is only necessary to park the vehicle at any one of the reference positions, and it is not necessary to establish a one-to-one correspondence between the vehicle and the reference position.

[0059] S1023, parking the vehicle at the reference position respectively;

[0060] In this step, the leading vehicle can park itself and other vehicles in the vehicle platoon at the reference position based on automatic driving technology; or other methods such as manual parking by the user can be used to park the vehicles in the vehicle platoon at the reference position. The present application does not limit the method of parking the vehicle at the reference position.

[0061] To further illustrate the above steps S1021-S1023, according to one embodiment of the present disclosure, the specified sound effect mode is 5.1.4 channel Dolby Atmos, but there are less than five vehicles in the vehicle fleet that are installed with the AVAS system, one of the vehicles can be determined as the leading vehicle to determine the reference positions of the loudspeakers. Then, the vehicles in the vehicle fleet can be parked to some of the reference positions, and the external loudspeakers and other devices are installed in the remaining reference positions to jointly form a sound field with 5.1.4 channel Dolby Atmos.

[0062] According to another embodiment of the present disclosure, 5.1.4 channel Dolby Atmos can be formed based on the AVAS system only. At this time, the full-range loudspeaker installed at the front of the vehicle in the AVAS system on the five vehicles is used as the full-range loudspeaker installed at the height of the human ear in a sitting position required by the sound effect mode; one of the subwoofers installed at the rear of the vehicle in the AVAS system on any one of the vehicles is used; and one of the full-range loudspeakers installed on the roof of the vehicle in the AVAS system on any four of the vehicles is used as the full-range loudspeaker installed on the ceiling required by the sound effect mode. In other words, to form 5.1.4 channel Dolby Atmos based on the loudspeakers of the AVAS system only, there must be at least five vehicles installed with the AVAS system in the vehicle fleet.

[0063] According to still another embodiment of the present disclosure, the specified sound effect mode is 5.1.4 channel Dolby Atmos, and there are exactly five vehicles installed with the AVAS system in the vehicle fleet. One of the vehicles can be determined as the leading vehicle to generate the vehicle fleet sound field orientation information in the specified sound effect mode, and the reference positions of the loudspeakers are determined according to the vehicle fleet sound field orientation information. Specifically, when the sound effect mode is 5.1.4 channel Dolby Atmos, the reference positions of the loudspeakers can be determined as the five vertices of a pentagon.

[0064] According to still another embodiment of the present disclosure, the specified sound effect mode is 5.1.4 channel Dolby Atmos, and there are more than five vehicles installed with the AVAS system in the vehicle fleet. The above-mentioned solution for "exactly five vehicles installed with the AVAS system" can be performed on any five of the vehicles, and the remaining vehicles do not participate in forming 5.1.4 channel Dolby Atmos; or one of the vehicles can be determined as the leading vehicle, and the other five vehicles are determined as non-leading vehicles, and the reference positions of the loudspeakers are determined by the leading vehicle according to the vehicle fleet sound field orientation information, but only the loudspeakers on the non-leading vehicles, external loudspeakers, and other loudspeaker devices participate in forming 5.1.4 channel Dolby Atmos.

[0065] In another aspect, according to an embodiment of the present disclosure, the reference positions of the loudspeakers can be determined based on the current position of the lead vehicle; and the distances between the reference positions can be determined based on the surrounding environment, the number of users, and other factors. Taking the Dolby Atmos of 5.1.4 channels as an example, a position near the current position of the lead vehicle can be determined as one vertex of a pentagon, and the length of the side of the pentagon and the positions of the other four vertices can be determined based on the number of users, the size of the parking space near the lead vehicle, and other factors, so as to obtain a pentagon with a proper size. It can be seen that the scheme disclosed in the present disclosure can park the vehicles in the vehicle fleet to appropriate positions, reserve sufficient activity space for the users, and minimize the distance of parking the vehicles in the vehicle fleet to the reference positions.

[0066] It should be noted that the loudspeakers used in the scheme disclosed in the present disclosure can be loudspeakers of the AVAS system, or loudspeakers of non-AVAS systems such as external loudspeakers; the scheme disclosed in the present disclosure is not limited to a specific sound effect mode, for example, it can be a two-channel mode, or a Dolby Atmos mode of 5.1.4, or other sound effect modes such as a 7.1.4 mode; when implementing the scheme disclosed in the present disclosure, any vehicle in the vehicle fleet can not be set as the lead vehicle, and the above embodiments should not be regarded as a limitation of the present disclosure.

[0067] S103, adjusting the loudspeakers based on the distances between the current vehicle and the other vehicles in the vehicle fleet, and the distance between the current vehicle and the center of the preset area, to form a sound field with a specified sound effect mode in the preset area.

[0068] In this step, the vehicles in the vehicle fleet can obtain the distances between the vehicles and the center of the preset area through radar or other distance detectors, and if there is a lead vehicle, the non-lead vehicles can send the obtained distances to the lead vehicle.

[0069] Then, the angles between each loudspeaker can be determined based on the distances between the current vehicle and the other vehicles in the vehicle fleet, and the distance between the current vehicle and the center of the preset area, and the volume of the enabled loudspeakers in the current vehicle can be adjusted. At this time, the enabled loudspeakers in the current vehicle and the loudspeakers in the other vehicles in the vehicle fleet can be controlled to play the same audio at the same time, so that the user can hear the audio with the specified sound effect in the preset area, thereby meeting the user's needs for listening to songs, watching movies, singing, and the like outdoors.

[0070] In addition, since the use scenario of the scheme disclosed in the present disclosure is usually outdoors, in order to further provide convenience for the user, according to an embodiment of the present disclosure, one or more specific audios can be played to drive away the mosquitoes around before playing the audio specified by the user.

[0071] The following still takes the Dolby Atmos of 5.1.4 channels as an example to further explain the above step S103. The lead vehicle can adjust the volume of the loudspeaker of each vehicle at the reference position based on the distance between each two vehicles in the vehicle fleet and the distance from each vehicle to the center of the preset area through a software algorithm capable of realizing the Atmos. Therefore, the scheme disclosed in the present application does not specifically limit the loudspeaker to be enabled for each vehicle, but only needs to ensure that the overall vehicle participating in forming the specified sound effect mode meets the requirement that the enabled loudspeaker meets the corresponding sound effect mode. According to the above software algorithm for adjusting the loudspeaker, the sound field of the specific sound effect mode can be formed. Exemplarily, when the sound effect mode is the Dolby Atmos of 5.1.4 channels, the loudspeaker enabled for each vehicle can be as shown in Figure 2B , or as shown in Figure 2C , and those skilled in the art can understand that Figure 2B , Figure 2C only shows a scenario in which the vehicle fleet exactly contains five vehicles installed with the AVAS system and only forms the Dolby Atmos of 5.1.4 channels based on the AVAS system; in addition, Figure 2B , Figure 2C only shows the loudspeaker required to form the Dolby Atmos of 5.1.4 channels, and any vehicle in the vehicle fleet can contain other loudspeakers not shown, and the content shown in the drawings should not be regarded as a limitation on the present application.

[0072] On the other hand, according to one embodiment disclosed in the present application, when the sound effect mode is the Dolby Atmos of 5.1.4 channels, the preset area can be the center area of the pentagon surrounded by the vehicles. Of course, those skilled in the art can flexibly set the position of the preset area according to the actual situation, and as an example, the present application further provides a method for determining the preset area, specifically comprising the following steps S1031-S1032:

[0073] S1031, identifying the position of the user through the camera and setting the position of the user as the preset area;

[0074] In this step, the vehicle can identify the position of the user through the camera and set the preset area. It can be understood that the camera used in this step is not limited to the camera of the current vehicle itself, but can also be the camera of other vehicles in the vehicle fleet. In addition, the application scenario of the scheme of the present application usually contains multiple users, according to one embodiment disclosed in the present application, the area with the most concentrated users can be set as the preset area, or other positions can be set as the preset area based on the selection of the user and other factors, and those skilled in the art can flexibly select the method for setting the preset area according to the actual situation.

[0075] S1032, detecting the change of the position of the user and judging whether to change the position of the preset area.

[0076] In this step, when a change in the user's location is detected, it can be determined whether the location of the preset area needs to be changed synchronously.

[0077] As mentioned above, the application scenarios of this application typically involve multiple users. If the location of any user is detected and the preset area is immediately changed, the preset area can easily be changed frequently, resulting in a poor user experience. Therefore, according to one embodiment disclosed in this application, when a user's location change is detected, the user can be asked whether the location of the preset area needs to be changed based on the user's choice. Alternatively, after the first question, it can be determined whether to fix the preset area in its current location to avoid frequent questioning of the user. Of course, those skilled in the art can flexibly formulate judgment criteria according to actual circumstances, and this application does not impose any limitations.

[0078] This application discloses a method for creating a sound field with a specific sound effect in a convoy. This method determines the reference position of the speakers on the vehicles based on the convoy sound field orientation information and parks the vehicles at the reference position. The convoy sound field orientation information at least represents the reference position of each speaker activated under the specified sound effect mode. Thus, the user only needs to park the vehicle in the designated location and control the vehicle to activate the corresponding speakers, or connect the required speakers externally near the vehicle, eliminating the need to manually install the speakers at the designated reference position, thus simplifying user operation. The speakers can then be adjusted based on the distance between any vehicle in the convoy and other vehicles in the convoy, as well as the distance between the vehicle and the center of a preset area, to create a sound field with the specified sound effect mode within the preset area. Furthermore, the position of the preset area can be set based on various factors such as user selection, further facilitating user operation.

[0079] Corresponding to the embodiments of the aforementioned methods, this application also provides a vehicle 200, such as... Figure 3A As shown, Figure 3A This is a block diagram illustrating an apparatus for a vehicle according to an exemplary embodiment of this application.
