[0059] In the following description, specific details such as specific system structures and techniques are provided for purposes of illustration rather than limitation to facilitate a thorough understanding of the embodiments of the present application. However, it will be apparent to those skilled in the art that the present application may be implemented in other embodiments without these specific details.

[0063] The term "and / or" describes an association between objects, indicating that three relationships can exist. For example, A and / or B means: A or B, or A and B.

[0064] Figure 1 This is a schematic diagram of the voice information transmission process in the existing car hands-free call control solution. Figure 1 As shown, in the existing process of making a call based on the car hands-free function, the mobile terminal of the user in the car (ie Figure 1 The first user's mobile terminal connects to the vehicle's computer via Bluetooth, improving the user's or driver's convenience during the call. The in-vehicle user's mobile terminal communicates with the second user's mobile terminal via a cellular network to complete the call. The first and second user mobile terminals can be portable devices such as mobile phones, tablets, and wristband communication devices.

[0065] During this process, the vehicle computer collects user voice information from the vehicle's microphone, processes and converts the voice information, and sends it to the first user's mobile terminal. It also receives user voice information sent from the second user's mobile terminal to the first user's mobile terminal, processes and converts the voice information, and sends it to the speaker for playback. The vehicle computer is responsible for converting and transmitting information between the first user's mobile terminal and the microphone and speaker.

[0066] This application aims to provide a new in-vehicle hands-free calling solution to achieve the connection between the first user's mobile terminal and the microphone and speaker, so as to avoid the vehicle computer being occupied by the call during driving and affecting the use of the driver or other passengers.

[0067] In an embodiment of the present invention, in order to facilitate the first user mobile terminal to be directly connected to the microphone and the speaker respectively, a communication module is set for the microphone and the speaker. Optionally, the communication module is a Star Flash module to communicate based on the Star Flash protocol, or the communication module is other communication modules that support a single management node to manage a certain number of managed nodes at the same time. Specifically, in the Star Flash system constructed according to the Star Flash system protocol stack architecture, the nodes in the system are divided into management nodes and managed nodes. In a specific application scenario, a single management node manages a certain number of managed nodes, and the management node is connected to these managed nodes to jointly complete specific communication functions. A single management node and the managed nodes connected to it together constitute a communication domain.

[0068] In order to make the purpose, technical solutions and advantages of this application clearer, specific embodiments will be described below with reference to the accompanying drawings.

[0069] Figure 2 This is a flowchart of an implementation method of a vehicle-mounted hands-free call control method provided by an embodiment of the present application. Figure 2 As shown, the method includes the following steps:

[0070] S201, the vehicle computer obtains a call request signal; wherein the call request signal is an incoming call request signal or an outgoing call request signal.

[0071] The method provided in the embodiment of the present application is performed by the vehicle computer. Optionally, the vehicle computer obtains a call request signal initiated by the user through a touch operation on the vehicle computer display screen, or obtains a call request signal sent by the mobile terminal side.

[0072] There are multiple ways for a user's mobile terminal to send a call request signal.

[0073] Optionally, when the vehicle computer is connected to the user's mobile terminal, it automatically monitors the call status of the user's mobile terminal. When the user's mobile terminal meets the set call status, the user's mobile terminal generates a call request signal. Alternatively, when the vehicle computer detects that the user's mobile terminal meets the set call status, it uses the call signal corresponding to the set call status as the call request signal. The set call status refers to the user's mobile terminal receiving an incoming call, voice request, or video request from an external mobile terminal, or the user's mobile terminal actively making a call, initiating a voice request, or initiating a video request.

[0074] Optionally, when the vehicle computer is not connected to the user's mobile terminal, if the user's mobile terminal receives an incoming call, voice request or video request sent by an external mobile terminal, or the user's mobile terminal actively makes an outgoing call, initiates a voice request or initiates a video request, the user's mobile terminal actively generates a call request signal or generates a call request signal based on the user's operation, and sends the call request signal to the vehicle computer.

[0075] S202: The vehicle computer switches the node type to a managed node and generates a first networking instruction according to the call request signal.

[0076] In the embodiments of this application, in a typical application scenario, the vehicle computer in an in-vehicle entertainment multimedia system serves as the management node, while the user's mobile terminal, microphone, and speaker serve as the vehicle computer's managed nodes. Communication between the vehicle computer, the user's mobile terminal, the microphone, and the speaker is based on the Star Flash protocol. When the user's mobile terminal enters a call state, the vehicle computer switches its node type to a managed node, adjusting the user's mobile terminal to serve as the management node.

[0077] In step S203 , the vehicle computer sends a first networking instruction to the user mobile terminal, the microphone, and the speaker to establish a call network with the user mobile terminal as the management node and the microphone and the speaker as the managed nodes.

[0078] When the vehicle computer is connected to multiple user mobile terminals, and these terminals are in a call state, a first networking instruction is generated based on a call request signal to instruct the user mobile terminal corresponding to the call request signal to act as a management node to establish its corresponding call network. The vehicle computer also acts as a management node to establish a communication network with other managed nodes.

[0079] Based on the characteristics of the Star Flash communication protocol that supports business scenarios with transmission requirements such as low latency, high reliability, precise synchronization, high concurrency, and high security, in this embodiment, the vehicle computer acts as both a management node and a managed node to support multiple scenarios concurrently. As a managed node, it establishes a call network with the user's mobile terminal, microphone, and speaker to support in-vehicle hands-free calling; as a management node, it establishes a communication network with other managed nodes to support in-vehicle communication or multimedia playback. For example, some of the speakers in the car can be used as managed nodes for the user's mobile terminal to support call voice playback, while the remaining speakers can be used as managed nodes for the vehicle computer to support multimedia audio playback.

[0080] In this embodiment, a call request signal is received by the vehicle computer, the node type is switched to a managed node of the user's mobile terminal, and a first networking instruction is generated based on the call request signal. This first networking instruction is sent to the user's mobile terminal, microphone, and speaker to establish a call network with the user's mobile terminal as the management node and the microphone and speaker as managed nodes. This ensures that when a call is connected, local voice pickup and playback of the other party's voice can be performed based on the established call network. In the call network with the user's mobile terminal as the management node, the user's mobile terminal communicates directly with the microphone and speaker, respectively, without the need for an intermediate information relay device. The user's mobile terminal receives voice information collected by the microphone and directly transmits the voice information to be played to the speaker. This simplifies the voice information transmission process, reduces call latency, and improves call efficiency.

[0081] Figure 3 This is a flow chart of voice information transmission during a hands-free call in a vehicle provided by an embodiment of the present application. Figure 3 As shown, after the call network is established based on the in-vehicle hands-free call control method provided in the embodiment of the present application, the user's mobile terminal is directly connected to the microphone and speaker, and there is no need for the vehicle computer to perform call signal conversion processing, thereby improving call efficiency.

[0082] In a specific embodiment, the vehicle includes multiple microphones and multiple speakers arranged in different positions. In different embodiments, the manner of constructing the call network is different.

[0083] Optionally, select some microphones as target microphones to improve the clarity of user conversations. This can prevent the user's mobile terminal from listening to conversations with other passengers, which could reduce the clarity of the conversation. Optionally, select some speakers as target speakers to prevent the entire vehicle's speakers from playing conversations and disturbing other passengers.

[0084] In a possible implementation, before sending the first networking instruction to the user mobile terminal, the microphone, and the speaker, the method further includes:

[0085] Identify the target microphone and target speaker.

[0086] Accordingly, the first networking instruction is sent to the user mobile terminal, the target microphone and the target speaker.

[0087] In this embodiment, some or all microphones and speakers are selected to perform call tasks based on the specific microphone and speaker configuration of the vehicle and the specific location of the user's mobile terminal in the vehicle, so as to ensure that the user's car experience is improved while meeting the call needs.

[0088] In different embodiments, the manner of determining the target microphone and the target speaker is different.

[0089] In one possible implementation, the vehicle system presets or allows the user to pre-set certain microphones and speakers corresponding to call functions as target microphones and target speakers for call networking. Each time a call network is established, the preset or user-set target microphones and target speakers are activated for networking.

[0090] In a possible implementation, determining a target microphone and a target speaker includes:

[0091] Determine the spatial position of the user's mobile terminal corresponding to the user in the vehicle;

[0092] Determine the target microphone and target speaker based on the spatial position and the microphone-speaker partition list.

[0093] In this embodiment, some microphones and speakers corresponding to the position partition are selected according to the spatial position of the user in the car corresponding to the user's mobile terminal, and the selected target microphone and target speaker are used as the managed nodes of the user's mobile terminal to ensure that the use of microphones and speakers in other partitions is not affected while meeting the call needs of the user's mobile terminal.

[0094] In different embodiments, the specific zoning rules for the space positions within the vehicle are different.

[0095] In an optional embodiment, the front row is partitioned with the driver and front passenger seats, and the rear seats are partitioned with the rear seats. When the user's mobile terminal corresponds to the driver, the microphones near the driver and front passenger seats are used as target microphones, and the speakers near the driver and front passenger seats are used as target speakers.

[0096] In another optional embodiment, the front row partition is formed with the main driver and the co-driver. When the back row of seats includes multiple rows, the partition is carried out in rows.

[0097] In another optional embodiment, each seat is used as an independent partition.

[0098] In this embodiment, by presetting a microphone and speaker partition list in the vehicle computer, after determining the spatial position of the user's mobile terminal corresponding to the user in the vehicle, the target microphone and target speaker are determined by looking up the table, thereby improving the call connection efficiency.

[0099] In a possible implementation, determining a target microphone and a target speaker includes:

[0100] Determining the communication distances with the user's mobile terminal, each microphone, and each speaker respectively;

[0101] Calculate the difference between the communication distance corresponding to each microphone and the communication distance corresponding to the user mobile terminal, and determine the microphone corresponding to the minimum difference as the target microphone;

[0102] The difference between the communication distance corresponding to each speaker and the communication distance corresponding to the user mobile terminal is calculated, and the speaker corresponding to the minimum difference is determined as the target speaker.

[0103] Among them, the communication distance between the vehicle computer and the user's mobile terminal, each microphone and each speaker is determined based on the Star Flash communication protocol, which can ensure the distance accuracy of about 5cm. The distance difference between the vehicle computer and the user's mobile terminal, each microphone and each speaker is calculated, and the microphone and speaker near the user's mobile terminal are determined according to the difference to establish a call network, thereby improving the clarity of the user's call.

[0104] Optionally, the vehicle computer determines the communication distance between the vehicle computer and the user mobile terminal, each microphone and each speaker based on other short-range communication protocols such as Bluetooth or WiFi, or the vehicle computer calculates the straight-line distance between the two seats based on the distribution orientation map of the system microphones, speakers and seats in the car, and the center point of each diagram. Communication distance.

[0105] In this embodiment, the target microphone and target speaker are determined based on the difference in communication distance, aiming to determine that the mobile terminal is connected to the microphone and speaker within a close range, so as to ensure that the microphone can more clearly collect the call voice information of the owner corresponding to the mobile terminal, and that when the speaker plays the other party's call voice, the owner corresponding to the mobile terminal can hear it more clearly.

[0106] In a possible implementation, all microphones and speakers are used as target microphones and target speakers, and serve as managed nodes of the user's mobile terminal.

[0107] In this embodiment, all microphones and speakers in the car are used as managed nodes of the user's mobile terminal, ensuring that the user's mobile terminal call is the highest priority task, avoiding the speaker playing other content affecting the call, and improving the call quality of the mobile terminal.

[0108] In one possible implementation, generating a first networking instruction according to a call request signal includes:

[0109] Parsing the call request signal to determine the user's mobile terminal identification;

[0110] A first networking instruction is generated according to the user mobile terminal identifier.

[0111] In this embodiment, when multiple passengers' mobile terminals send call request signals to the vehicle computer, the vehicle computer can generate a first networking instruction for each mobile terminal to simultaneously establish multiple call networks in the vehicle while ensuring the call clarity of multiple mobile terminals.

[0112] In a possible implementation, after generating the first networking instruction according to the call request signal, the method further includes: generating a volume increase instruction and sending the volume increase instruction to the target speaker.

[0113] In this embodiment, a volume increase instruction is generated to increase the volume of the target speaker to clearly play the other party's call voice, ensuring that the user corresponding to the mobile terminal in the car can clearly hear the other party's call voice.

[0114] In a possible implementation, after generating the first networking instruction according to the call request signal, the method further includes: generating a volume reduction instruction and sending the volume reduction instruction to speakers other than the target speaker.

[0115] In this embodiment, a volume reduction instruction is generated to reduce the volume of speakers other than the target speaker to prevent the multimedia information played by the in-vehicle entertainment system from affecting the clarity of the user's call voice collected by the mobile terminal, while ensuring that the user can clearly hear the other party's call voice.

[0116] In a possible implementation, after generating the first networking instruction according to the call request signal, the method further includes:

[0117] Generate a volume-up command and send the volume-up command to the target speaker;

[0118] A volume down command is generated and sent to speakers other than the target speaker.

[0119] In this embodiment, a volume increase instruction and a volume decrease instruction are generated to increase the playback volume of the target speaker and reduce the playback volume of other speakers to ensure the clarity of the user's call throughout.

[0120] In a possible implementation, the method further includes:

[0121] Obtaining a call end signal sent by the user's mobile terminal;

[0122] Switch the node type to a management node and send a second networking instruction to the user's mobile terminal, microphone, and speaker, making the user's mobile terminal, microphone, and speaker the managed nodes;

[0123] The first networking instruction and the second networking instruction include management node information.

[0124] After the local user actively ends a call or the other party ends the call, the user's mobile terminal generates a call end signal based on the call end status and sends it to the vehicle computer, instructing the host to restore the pre-call networking state through a second networking command. The networking command includes management node information, which allows the microphone and speaker to confirm the management node and quickly complete the networking. After the network is restored, the microphone and speaker continue to serve as managed nodes of the vehicle computer, improving the user experience.

[0125] In this embodiment, the vehicle computer, microphone and speaker can realize dynamic and free networking. When a call request is received from the user's mobile terminal, a call network with the user's mobile terminal as the management node can be constructed to support the implementation of the in-vehicle hands-free calling function. When the call is over, the dynamic networking is completed to meet other functional requirements such as multimedia playback in the car, thereby improving the user's car experience.

[0126] It should be understood that the size of the serial numbers of the steps in the above embodiments does not mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of this application.
