[0067] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0068] refer to Figure 1 , Figure 1 The following is a schematic diagram of a Bluetooth-based vehicle-to-vehicle call method according to an embodiment of the present application. Figure 1 As shown, the present application provides a Bluetooth-based vehicle-to-vehicle call method, comprising:

[0069] Step S1: When the vehicle needs to initiate an out-of-vehicle call, a Bluetooth communication connection is established with other Bluetooth-enabled call devices around the vehicle through the vehicle's Bluetooth module.

[0070] In this embodiment, when the vehicle needs to initiate an outside-vehicle call, the vehicle's Bluetooth module searches for other Bluetooth-enabled call devices around the vehicle body, and then the vehicle's Bluetooth module establishes a Bluetooth communication connection with the other Bluetooth-enabled call devices around the vehicle that have been searched.

[0071] Step S2: The other Bluetooth-enabled communication device is used as a communication-enabled device, and a communication request is initiated to the communication-enabled device through the Bluetooth module of the vehicle.

[0072] In this embodiment, since there are multiple other Bluetooth-enabled call devices searched, the other Bluetooth-enabled call devices searched are used as optional call-enabled devices, and then the user of the vehicle selects one of the other Bluetooth-enabled call devices as the call-enabled device. At this time, the Bluetooth module of the vehicle initiates a call request to the call-enabled device, and the vehicle is the vehicle currently initiating the out-of-vehicle call.

[0073] Step S3: Receive the wireless call frequency band sent by the Bluetooth module of the communication device through the Bluetooth module of the vehicle

[0074] In this embodiment, after the call-enabled device receives a call request sent by the vehicle that initiated the inter-vehicle call, a pop-up window prompt is displayed in the call-enabled device to inform the object corresponding to the call-enabled device that a vehicle currently requests to talk with itself. In the case that the call-enabled device rejects the call, feedback information of rejecting the call is fed back to the vehicle that initiated the inter-vehicle call. Based on the received feedback information, the vehicle that initiated the inter-vehicle call pops up a window prompting the user in the vehicle that initiated the inter-vehicle call that the current call-enabled device rejects the call with it.

[0075] In this embodiment, based on whether the call-enabled device agrees to make a call with the user in the vehicle that initiates the call outside the vehicle, the call-enabled device will send feedback information to the vehicle that initiates the call outside the vehicle. The vehicle that initiates the call outside the vehicle receives the feedback information. When the call-enabled device agrees to make the call, the wireless call frequency band will be fed back. After both wireless call modules are connected to the wireless call frequency band, the call can be made.

[0076] Step S4: Based on the wireless call frequency band sent by the Bluetooth module of the communication device, a vehicle-to-vehicle wireless call communication connection is established through the wireless call module of the vehicle and the wireless call module of the communication device.

[0077] In this embodiment, after the vehicle initiating the inter-vehicle call receives the feedback information returned by the call-enabled device, the feedback information is analyzed to determine whether it agrees to the vehicle initiating the inter-vehicle call to communicate with it. If agreed, the wireless call module of the call device on the vehicle initiating the inter-vehicle call establishes a vehicle-to-vehicle wireless call communication connection with the wireless call module of the call-enabled device based on the wireless call frequency band in the feedback information.

[0078] Step S5: The sound inside the vehicle is collected through the vehicle-mounted microphone, and sent to the wireless call module of the communication device through the wireless call module of the vehicle.

[0079] In this embodiment, based on the inter-vehicle wireless call communication connection established between the vehicle that initiates the inter-vehicle call and the call-enabled device, the vehicle-mounted microphone of the vehicle that initiates the inter-vehicle call collects the sound inside the vehicle, and then based on the established inter-vehicle wireless call communication connection, the sound is sent to the wireless call module of the call-enabled device through the wireless call module of the call device of the vehicle that initiates the inter-vehicle call.

[0080] The embodiment of the present application provides a method for making calls outside the vehicle based on Bluetooth. When the vehicle needs to initiate a call outside the vehicle, a Bluetooth communication connection is established with other Bluetooth-enabled call devices around the vehicle through the Bluetooth module of the vehicle; the other Bluetooth-enabled call devices are used as call-enabled devices, and a call request is initiated to the call-enabled devices through the Bluetooth module of the vehicle; the wireless call frequency band sent by the Bluetooth module of the call-enabled device is received through the Bluetooth module of the vehicle; based on the wireless call frequency band sent by the Bluetooth module of the call-enabled device, a vehicle-to-vehicle wireless call communication connection is established through the wireless call module of the vehicle and the wireless call module of the call-enabled device; the sound inside the vehicle is collected through the vehicle-mounted microphone, and sent to the wireless call module of the call-enabled device through the wireless call module of the vehicle. Therefore, based on this method, users can talk to people outside the vehicle without getting off the vehicle, thereby effectively reducing the user's call cost and improving the user's call experience.

[0081] In combination with the above embodiments, in one implementation, the embodiment of the present application further provides a method for making calls outside a vehicle based on Bluetooth. In the method for making calls outside a vehicle based on Bluetooth, the method further includes: receiving the network call demand of the device capable of making calls sent by the Bluetooth module of the device capable of making calls through the Bluetooth module of the vehicle; establishing a vehicle network call communication connection between the vehicle network module of the vehicle and the vehicle network module of the device capable of making calls through the vehicle network module of the vehicle; collecting the sound inside the vehicle through the vehicle-mounted microphone of the vehicle, and sending it to the vehicle network module of the device capable of making calls through the vehicle network module of the vehicle.

[0082] In this embodiment, the user in the vehicle that initiates the out-of-vehicle call has a higher willingness to talk with other calling devices. Therefore, in this scenario, the other calling devices occupy a dominant position. In order to make the calling experience better, this application determines whether to agree to talk with the user in the vehicle that initiates the out-of-vehicle call by the call-enabled device that receives the call request sent by the vehicle that initiates the out-of-vehicle call, and determines which specific call type to use with the user in the vehicle that initiates the out-of-vehicle call. The call type includes but is not limited to a call type that transmits the call content in a wireless call frequency band and a call type that conducts the call in the form of an Internet phone call.

[0083] Specifically: when the user on the vehicle that initiates the out-of-car call wants to talk to the talkable device in a one-to-one call mode, the Bluetooth module on the vehicle that initiates the out-of-car call sends a call request to the talkable device, and the call request will record the information that the vehicle that initiates the out-of-car call wants to talk to the talkable device in a one-to-one call mode. At this time, a pop-up window prompt will be displayed on the talkable device to inform the object corresponding to the talkable device that there is currently a vehicle requesting to talk to itself, and the content displayed in the pop-up window also includes the information recorded in the call request that the vehicle that initiates the out-of-car call wants to talk to the talkable device in a one-to-one call mode. In the case that the talkable device is a call device on the talkable vehicle, in order to enable the object corresponding to the talkable device to accurately know which vehicle wants to talk to itself, the location information of the vehicle that initiates the out-of-car call relative to the talkable device (such as the vehicle that currently initiates the out-of-car call is located 1.5m to the left and 6m behind the talkable device) and the attribute information of the vehicle that initiates the out-of-car call are displayed in the pop-up window of the talkable device. When the object corresponding to the device capable of communication agrees to communicate with the vehicle initiating the inter-vehicle call, the object corresponding to the device capable of communication directly clicks the confirmation button in the pop-up window to indicate that the object corresponding to the device capable of communication agrees to the call. At this time, the object corresponding to the device capable of communication will continue to select the type of call to be used for the call, wherein the object corresponding to the device capable of communication is the target object. After selecting the network call type, the connection information required for establishing the network call communication connection between the vehicle initiating the inter-vehicle call and the device capable of communication is then sent to the Bluetooth module of the vehicle initiating the inter-vehicle call through the Bluetooth module of the device capable of communication. Among them, the connection information corresponds to the call type. When the call type determined by the call-capable device is different, the connection information is also different. When the call type is a call type that transmits the call content in a wireless call frequency band, the connection information is a specific wireless call frequency band, so as to realize the call connection between the call device on the vehicle initiating the out-of-vehicle call and the call-capable device. After the call connection is established, the Bluetooth module on the vehicle initiating the out-of-vehicle call and the Bluetooth module of the call-capable device will be able to send and receive call content to each other; when the call type is a call type that uses an Internet phone, the connection information is the Internet phone information of the call-capable device, which includes but is not limited to telephone numbers, instant messaging ID information that can be searched, etc. The vehicle initiating the out-of-vehicle call will be able to establish a wireless call communication connection with the call-capable device based on the Internet phone information, so that they can conduct an Internet phone call with each other.

[0084] In this embodiment, the Internet of Vehicles module of the call device on the vehicle that initiates the out-of-vehicle call establishes a vehicle-to-vehicle network call communication connection with the Internet of Vehicles module of the call device on the call-enabled device based on the received connection information corresponding to the network call, and then collects the sound inside the vehicle through the on-board microphone of the vehicle that initiates the out-of-vehicle call, and sends it to the Internet of Vehicles module of the call-enabled device through its own Internet of Vehicles module.

[0085] In combination with the above embodiments, in one implementation, the embodiment of the present application also provides a method for making calls outside a vehicle based on Bluetooth. In the method for making calls outside a vehicle based on Bluetooth, when multiple other calling devices with Bluetooth enabled are used as multiple call-enabled devices, the call request also includes: a one-to-many call mode and a wireless call frequency band of the wireless call module of the vehicle; based on the wireless call frequency band of the wireless call module of the vehicle, establishing a vehicle-to-vehicle wireless call communication connection through the wireless call module of the vehicle and the wireless call modules of the multiple call-enabled devices; collecting the sound inside the vehicle through the vehicle-mounted microphone, and broadcasting it to the wireless call modules of the multiple call-enabled devices through the wireless call module of the vehicle.

[0086] In this embodiment, since the one-to-many call mode is that multiple talkable devices establish a connection with the call device on the vehicle that initiates the vehicle-to-vehicle call to conduct a group call, if each talkable device selects the call type based on its own will, and in the end, multiple call types are selected, the one-to-many call connection will not be established. Therefore, it is not convenient for the talkable device that receives the call request to select the call type based on its own will for the one-to-many call mode. Therefore, in this application, when the vehicle that initiates the vehicle-to-vehicle call wants to conduct the vehicle-to-vehicle call in a one-to-many call mode, the call request sent by the vehicle that initiates the vehicle-to-vehicle call to each talkable device will directly record the information that the vehicle that initiates the vehicle-to-vehicle call wants to communicate with each talkable device in a one-to-many call mode, and record the call type that the vehicle that initiates the vehicle-to-vehicle call wants to communicate with each talkable device, and the call type can be a network call or a call based on the wireless call frequency band of the wireless call module, and record the connection information of the vehicle that initiates the vehicle-to-vehicle call, and the connection information corresponds to the call type.

[0087] Specifically: when a user on a vehicle that initiates an out-of-car call wants to talk to multiple devices that can talk in a one-to-many call mode, the Bluetooth module on the vehicle that initiates the out-of-car call sends a call request to each device that can talk. The call request will record the information that the vehicle that initiates the out-of-car call wants to talk to the devices that can talk in a one-to-many call mode, and record the call type that the vehicle that initiates the out-of-car call wants to talk to each device that can talk, and record the connection information corresponding to the call type of the vehicle that initiates the out-of-car call. At this time, a pop-up window prompt will be displayed in each device that can talk to inform the object corresponding to each device that can talk that there is currently a vehicle requesting to talk to itself. At the same time, the content displayed in the pop-up window also includes the information recorded in the call request that the vehicle that initiates the out-of-car call wants to talk to the device that can talk in a one-to-many call mode and with the corresponding call type. When the object corresponding to the device that can talk agrees to talk with the vehicle that initiates the out-of-car call in a one-to-many call mode and the corresponding call type in the call request, the object corresponding to the device that can talk directly clicks the confirmation button of the pop-up window to indicate that the object corresponding to the device that can talk agrees to the call. After agreeing to the call, each talkable device establishes a corresponding call communication connection with the call device on the vehicle initiating the out-of-car call based on the received connection information. The connection information corresponds to the call type. When the call type determined by the talkable device is different, the connection information is also different. When the call type is a call type that transmits the call content in a wireless call frequency band, the connection information is a specific wireless call frequency band, so as to realize the call connection between the call device on the vehicle initiating the out-of-car call and the talkable device. After the call connection is established, the wireless call module on the vehicle initiating the out-of-car call and the wireless call module of the talkable device can send and receive the call content to each other; when the call type is a call type that uses an Internet phone, the connection information is the Internet phone information of the call device on the vehicle initiating the out-of-car call, and the Internet phone information includes but is not limited to the phone number, the ID information of the instant messaging that can be searched, etc. The talkable device can establish an Internet call communication connection with the call device on the vehicle initiating the out-of-car call based on the Internet phone information, so that they can conduct an Internet phone call with each other.

[0088] In this embodiment, when the call request includes a one-to-many call mode and the wireless call frequency band of the wireless call module of the vehicle, based on the wireless call frequency band of the wireless call module on the vehicle that initiates the call outside the vehicle, a vehicle-to-vehicle wireless call communication connection is established between the wireless call module on the vehicle that initiates the call outside the vehicle and the wireless call modules of multiple call-capable devices; then, the sound inside the vehicle is collected through the on-board microphone on the vehicle that initiates the call outside the vehicle, and broadcasted to the wireless call modules of multiple call-capable devices through the wireless call module on the vehicle that initiates the call outside the vehicle.

[0089] In this embodiment, under the configuration restriction of the vehicle initiating the inter-vehicle call, the vehicle initiating the inter-vehicle call may only support one call type, and in this case, the call type cannot be selected by the call-enabled device on the opposite side. Therefore, in the present application, when the vehicle initiating the inter-vehicle call only supports one call type, no matter whether the vehicle initiating the inter-vehicle call wants to have a one-to-one call with a single call-enabled device or a one-to-many call with multiple call-enabled devices, the vehicle initiating the inter-vehicle call will record in the call request the information about the call mode in which the vehicle initiating the inter-vehicle call wants to talk with the call-enabled device, the call type in which the vehicle initiating the inter-vehicle call wants to talk with the call-enabled device, and the connection information corresponding to the call type of the vehicle initiating the inter-vehicle call.

[0090] Based on the received call request, the talkable device will display a pop-up window prompt in the talkable device to inform the object corresponding to the talkable device that there is currently a vehicle requesting to talk with itself. At the same time, the content displayed in the pop-up window also includes information recorded in the call request about what call mode and call type the vehicle initiating the off-vehicle call wants to use with the talkable device. If the object corresponding to the talkable device agrees to talk with the vehicle initiating the off-vehicle call in the corresponding call mode and call type, the object corresponding to the talkable device directly clicks the confirmation button in the pop-up window to indicate that the object corresponding to the talkable device agrees to the call. After agreeing to the call, the talkable device establishes a corresponding wireless call communication connection with the call device on the vehicle initiating the off-vehicle call based on the received connection information.

[0091] In combination with the above embodiments, in one implementation, the embodiment of the present application also provides a method for making calls outside a vehicle based on Bluetooth. In the method for making calls outside a vehicle based on Bluetooth, the method further includes: configuring the search range of the Bluetooth module of the vehicle; when the Bluetooth of the vehicle is turned on, searching for other Bluetooth-enabled call devices within the search range and displaying them on the available call list; establishing a Bluetooth communication connection with other call devices on the available call list through the Bluetooth module of the vehicle; updating and displaying the available call list when the vehicle needs to initiate a call; and using other Bluetooth-enabled call devices in the updated available call list as available call devices.

[0092] In this embodiment, in order to meet the personalized use needs of users, the present application can adjust the search range of the Bluetooth module, and adjust the search range of the Bluetooth module by adjusting the power of the Bluetooth module. Specifically: when the user on the vehicle who initiates the off-vehicle call wants to talk to other call devices within a certain range, the search range of the vehicle's Bluetooth module is configured by adjusting the power of the Bluetooth module. Then, when the vehicle turns on Bluetooth, the vehicle searches for other call devices with Bluetooth turned on within the configured search range, and displays the device information of all other call devices on the call list of the vehicle interface. Among them, the device information of the call device can be the identification information of the vehicle that can talk, or it can be the identification information of the mobile terminal. Among them, the identification information of the vehicle that can talk includes but is not limited to the body color, model, license plate and other information, and the identification information of the mobile terminal includes but is not limited to the gender, clothing and other information of the user to whom the mobile terminal belongs. Then, the vehicle's Bluetooth module establishes a Bluetooth communication connection with other call devices on the call list, and when the vehicle needs to initiate a call, the call list is updated and displayed, and then the other call devices with Bluetooth turned on in the updated call list are used as call devices.

[0093] In combination with the above embodiments, in one implementation, the embodiment of the present application also provides a method for making calls outside the vehicle based on Bluetooth. In the method for making calls outside the vehicle based on Bluetooth, the method further includes: receiving the identity verification information of the call-enabled device sent by the call-enabled device through the Bluetooth module of the vehicle, the identity verification information including: the first certificate of the call-enabled device and the verification information encrypted by the call-enabled device using the first private key; decrypting the verification information encrypted by the first private key using the public key in the first certificate of the call-enabled device to obtain the decrypted verification information; encrypting the decrypted verification information using the second private key of the vehicle to obtain the verification information encrypted by the second private key of the vehicle; sending the second certificate of the vehicle and the verification information encrypted by the second private key to the call-enabled device. The vehicle performs identity authentication; when the identity authentication of the talk-capable device is passed, receives the symmetric encryption and decryption information sent by the talk-capable device, the symmetric encryption information is obtained by encrypting based on the public key in the second certificate; decrypts the received symmetric encryption and decryption information by using the private key of the vehicle to obtain the symmetric key and the encryption and decryption algorithm; collects the sound inside the vehicle by using the vehicle-mounted microphone, and sends it to the wireless call module of the talk-capable device through the wireless call module of the vehicle, including: collects the sound inside the vehicle by using the vehicle-mounted microphone, and encrypts it by using the symmetric key and the encryption and decryption algorithm, and then sends it to the wireless call module of the talk-capable device through the wireless call module of the vehicle.

[0094] In this embodiment, after the wireless call module of the call device on the vehicle initiating the out-of-car call establishes a wireless call communication connection with the wireless call module of the call-capable device, before the call content is transmitted to each other, this application will perform identity authentication and call content encryption channel construction for the call device on the vehicle initiating the out-of-car call and the call-capable device, specifically:

[0095] The Bluetooth module of the call device on the vehicle that initiates the out-of-car call will also feedback the identity verification information of the call device while receiving the connection information fed back by the call device. The identity verification information includes the first certificate of the call device and the verification information encrypted by the call device using the first private key. The call device on the vehicle that initiates the out-of-car call parses the identity verification information to obtain the first certificate of the call device and the verification information encrypted by the first private key of the call device in the identity verification information. The first certificate includes the public key of the call device, and the public key is used to decrypt the content encrypted by the first private key of the call device. The call device on the vehicle that initiates the out-of-car call decrypts the verification information encrypted by the first private key of the call device based on the public key in the first certificate to obtain the decrypted verification information. The unencrypted verification information is preferably a random number randomly generated by the call device. Then the call device on the vehicle that initiates the out-of-car call encrypts the decrypted verification information by using its own second private key to obtain the verification information encrypted by the call device on the vehicle that initiates the out-of-car call by using its own second private key. The verification information obtained by the call device on the vehicle initiating the out-of-vehicle call encrypted by its own second private key and the second certificate of the call device on the vehicle initiating the out-of-vehicle call are sent to the call-enabled device for identity authentication. When the call-enabled device passes the identity authentication of the call device on the vehicle initiating the out-of-vehicle call based on the received second certificate and the verification information encrypted by the call device on the vehicle initiating the out-of-vehicle call by its own second private key, the call-enabled device will send its own symmetric encryption information to the call device on the vehicle initiating the out-of-vehicle call. The symmetric encryption information is obtained by encrypting the public key in the second certificate of the call device on the vehicle initiating the out-of-vehicle call. The corresponding symmetric encryption information can only be decrypted by the second private key of the call device on the vehicle initiating the out-of-vehicle call. After receiving the symmetric encryption information, the call device on the vehicle initiating the out-of-vehicle call decrypts the symmetric encryption information based on its own second private key to obtain the symmetric key and encryption and decryption algorithm, so that the call-enabled device and the call device on the vehicle initiating the out-of-vehicle call both have the symmetric key and encryption and decryption algorithm, so that the call content can be encrypted and decrypted based on the symmetric key and encryption and decryption algorithm. Compared with the symmetric encryption method, there is a risk of theft if the symmetric key is leaked or cracked by brute force during the process. The asymmetric encryption method will have a negative impact on the call quality due to the large amount of calculation. The implementation method of encrypting and decrypting the call content in the present application will not increase the extra processing time and cause delays like asymmetric encryption, and can also avoid the problem of private key leakage during the symmetric encryption process.

[0096] In combination with the above embodiments, in one implementation, the embodiment of the present application further provides a method for making calls outside a vehicle based on Bluetooth. In the method for making calls outside a vehicle based on Bluetooth, the second certificate of the vehicle and the verification information encrypted with the second private key are sent to the call-enabled device for identity authentication, including: sending the verification information encrypted with the second private key to the call-enabled device to control the call-enabled device to decrypt the verification information encrypted with the second private key based on the public key in the received second certificate to obtain the decrypted verification information; and determining that the identity authentication is successful when the decrypted verification information obtained by the call-enabled device is the same as the verification information sent by the call-enabled device.

[0097] In this embodiment, the second certificate sent by the other call device and received by the call device includes the public key of the other call device. Based on the public key, the call device can decrypt the verification information sent by the other call device and encrypted by the second private key of the other call device to obtain the decrypted verification information. After the call device decrypts and obtains the verification information, it compares the verification information with the verification information sent by itself to the call device on the vehicle that initiates the out-of-car call to obtain the corresponding comparison result. If the comparison result shows that the verification information sent by the call device is consistent with the verification information received, it is determined that the identity authentication of the other call device is passed, indicating that the other call device belongs to the call device on the vehicle that initiates the out-of-car call. At this time, the call device will send the encrypted symmetric encryption information to the other call device. If the comparison result is inconsistent, it is determined that the identity authentication of the other call device is not passed, indicating that the other call device does not belong to the call device on the vehicle that initiates the out-of-car call. At this time, the symmetric encryption information is not sent to the other call device, so that the call device that wants to steal the call content by a third party will not be able to obtain the symmetric key and encryption and decryption algorithm used to encrypt and decrypt the call content.

[0098] In this embodiment, if Figure 3 As shown, based on the wireless call communication connection established between the wireless call module of the call device on the vehicle initiating the out-of-car call and the wireless call module of the call-enabled device, the user's call content is collected through the microphone on the vehicle initiating the out-of-car call, and the call content is sent to the digital signal processor of the vehicle for processing to obtain a corresponding digital signal. The digital signal processor is preferably a DSP chip.

[0099] In this embodiment, after the digital signal corresponding to the call content is obtained, the digital signal is encrypted by the encryption and decryption module on the vehicle based on a determined symmetric key and an encryption and decryption algorithm.

[0100] In this embodiment, after obtaining the encrypted digital signal, the encrypted digital signal is sent to the wireless call module of the communication device through the wireless call module of the vehicle, and after receiving the encrypted digital signal, the wireless call module of the communication device also decrypts the encrypted digital signal based on the determined symmetric key and encryption and decryption algorithm through the encryption and decryption module of the communication device to obtain a decrypted digital signal, and then processes the decrypted digital signal and converts it into a corresponding audio signal for output. In particular, when the object corresponding to the communication device is other vehicles, the decrypted digital signal is also processed using a digital signal processor; and when the object corresponding to the communication device is a pedestrian, the communication device is a mobile communication device (such as a mobile phone, etc.), and the mobile communication device will be configured with a wireless communication module and an encryption and decryption module.

[0101] In this embodiment, during the call, the communication process of the call content is mutual. The user on the vehicle initiating the out-of-car call will send the call content to the object corresponding to the call-enabled device, and similarly, the object corresponding to the call-enabled device will send the call content to the vehicle initiating the out-of-car call. Therefore, the vehicle initiating the out-of-car call will also receive the encrypted digital signal sent by the call-enabled device, and the encrypted digital signal records the call content sent by the object corresponding to the call-enabled device to the vehicle initiating the out-of-car call. At this time, the wireless call module on the vehicle initiating the out-of-car call receives the encrypted digital signal sent by the call-enabled device.

[0102] In this embodiment, the encryption and decryption module on the vehicle that initiates the inter-vehicle call decrypts the encrypted digital signal based on the determined symmetric key and encryption and decryption algorithm to obtain a decrypted digital signal.

[0103] In this embodiment, after the decrypted digital signal is obtained, the decrypted digital signal is processed by a digital signal processor on the vehicle that initiates the inter-vehicle call to obtain a corresponding audio signal.

[0104] In this embodiment, the obtained audio signal is output through the speaker of the vehicle that initiates the inter-vehicle call, so that the user in the vehicle that initiates the inter-vehicle call can receive the call content sent by the object corresponding to the call-enabled device.

[0105] In combination with the above embodiments, in one implementation, the embodiment of the present application further provides a method for making an out-of-car call based on Bluetooth. In the method for making an out-of-car call based on Bluetooth, the method further includes: obtaining driving scene data collected by various sensors of the vehicle, the driving scene data including sensor data, vehicle positioning data and user operation data; determining whether the current driving scene meets the target driving scene for initiating an out-of-car call by analyzing and processing the driving scene data; and determining that the vehicle needs to initiate an out-of-car call when it is determined that the current driving scene meets the target driving scene.

[0106] In this embodiment, a virtual button can be set on the display screen of the vehicle or a physical button can be set on the vehicle. The initiation of an out-of-car call can be controlled by the virtual button or the physical button. After the user clicks the virtual button, it is determined that an out-of-car call needs to be initiated at this time, and a call list is rendered and displayed accordingly, and a call request is sent to the callable device based on the callable device further selected by the user in the callable list. The physical button can be an existing button of the vehicle, and the initiation of an out-of-car call is controlled by double-clicking or long pressing the existing button. After the user long presses the existing button, it is determined that an out-of-car call needs to be initiated at this time, and a call list is displayed accordingly, and a call request is sent based on the callable device further selected by the user in the callable list. At the same time, it can be determined whether an out-of-car call needs to be initiated based on the data obtained by various sensors of the vehicle. Specifically: driving scene data collected by various sensors of the vehicle are obtained, and the driving scene data include sensor data collected by vehicle sensors, vehicle positioning data and user operation data, and then the driving scene data are analyzed and processed to determine whether the current driving scene meets the target driving scene for initiating an out-of-car call. When it is determined that the current driving scene meets the target driving scene, it is determined that the vehicle needs to initiate an out-of-car call. For example, when it is determined based on monitoring data that the front vehicle has been driving parallel to a large truck at a low speed for a long time, it is determined that an out-of-car call needs to be initiated at this time, and a list of available calls is displayed accordingly, and a call request is sent to the call device of the front vehicle based on the front vehicle selected by the user in the list of available calls. At the same time, it can be determined based on the vehicle's positioning data whether an out-of-car call needs to be initiated. For example, when it is determined based on the vehicle's positioning data that the vehicle is currently in a highway, tunnel, intersection, etc., it is determined that an out-of-car call needs to be initiated at this time, and a list of available calls is displayed accordingly, and a call request is sent based on the call device selected by the user in the list of available calls. For example, in high-risk scenarios such as highways, tunnels, intersections, etc. where it is inconvenient to get off the vehicle or the mobile phone has no signal, a communication method is provided, such as reminding the front vehicle not to drive parallel to a large truck at a low speed for a long time, and reminding nearby vehicles of malfunctions, thereby reducing the accident rate and ensuring driving safety; if the terminal carried by pedestrians has a wireless call module, it can talk to pedestrians and give way to pedestrians.

[0107] In combination with the above embodiments, in one implementation, the embodiment of the present application further provides a method for making calls outside a vehicle based on Bluetooth. In the method for making calls outside a vehicle based on Bluetooth, the method further includes: comparing the current power level of the vehicle with a set power level threshold to obtain a comparison result; if the comparison result shows that the power level is lower than the set power level threshold, switching to receiving and sending call requests by the UWB module and making a wireless call communication connection by the UWB module.

[0108] In this embodiment, the UWB module has low power consumption, and the energy consumption used under the premise of the same information will be lower. Therefore, the present application compares the power of the vehicle initiating the out-of-car call with the set power threshold to obtain the corresponding comparison result. When the comparison result is that the power is higher than the set power threshold, the Bluetooth module is selected to send and receive call requests. When the Bluetooth module is selected to send and receive call requests, the call device for the out-of-car call needs to be provided with a wireless call module, and the call devices for the out-of-car call establish a wireless call communication connection through the wireless call module to talk. When the comparison result is the first set power threshold of the power, the UWB module is selected to send and receive call requests and establish a wireless call communication connection. The UWB module is also used to send and receive call requests and establish a wireless call communication connection.
