[0046] This embodiment provides a Bluetooth automatic connection method, device, user equipment, and vehicle equipment, which can avoid the need for users to manually operate for authentication when establishing a Bluetooth connection for the first time, and achieve automatic authentication without the need for user access confirmation when establishing a Bluetooth connection for the first time.

[0047] Figure 1 It is shown as an application schematic diagram of the Bluetooth automatic connection method of this embodiment. Figure 1 In the user equipment 10 includes but is not limited to intelligent mobile devices of users such as mobile phones, PADs, wearable devices, intelligent AI devices, etc. Among them, an application program (such as a screen mirroring application program, a vehicle head unit control program, etc.) is installed in the user equipment 10. The Figure 1 In the vehicle equipment 20 is installed in the vehicle 30, and the vehicle 30 is a car or a two-wheeled electric vehicle. The vehicle equipment 20 includes but is not limited to an in-vehicle head unit, an in-vehicle box, etc. installed with a Bluetooth module, which can establish a connection with the user equipment 10 through Bluetooth and interact with the application program in the user equipment 10. Such as Figure 1As shown, in the Bluetooth automatic connection method of this embodiment, when the user device 10 with the application installed and the in-vehicle device 20 in the vehicle 30 have established a connection through a non-Bluetooth wireless network (such as wifi, GPRS, 2 / 3 / 4 / 5G wireless network), when the user device 10 and the in-vehicle device 20 perform the first Bluetooth connection, the first Bluetooth connection is authenticated based on the authentication code of the user device 10 pre-stored in the in-vehicle device 20 to confirm that the Bluetooth connection is a secure connection, and the Bluetooth connection between the user device 10 and the in-vehicle device 20 is established, enabling the user to avoid the need for manual operation by the user for authentication during the first establishment of the Bluetooth connection, realizing automatic authentication without the need for user access confirmation during the first establishment of the Bluetooth connection, and improving the convenience of the Bluetooth connection.

[0048] The principles and implementation manners of the Bluetooth automatic connection method, the user device 10, and the storage medium of this embodiment will be elaborated in detail below, enabling those skilled in the art to understand the Bluetooth automatic connection method, the user device 10, and the storage medium of this embodiment without creative labor.

[0049] This embodiment provides a Bluetooth automatic connection method. Figure 2 It is shown as the principle flowchart when the Bluetooth automatic connection method of this embodiment is applied to the user device. As Figure 2 shown, the Bluetooth automatic connection method includes the following steps:

[0050] Step S110: When detecting a Bluetooth demand signal sent by the application, start the Bluetooth connection and determine whether the Bluetooth connection is the first connection;

[0051] Step S120: When the Bluetooth connection is the first connection, obtain the authentication code from the in-vehicle device through the pre-established non-Bluetooth wireless network;

[0052] Step S130: Authenticate the Bluetooth connection initiated by the application based on the authentication code;

[0053] Step S140: After the Bluetooth connection initiated by the application passes the authentication, confirm that the Bluetooth connection initiated by the application is a secure connection, and establish the Bluetooth connection between the user device and the in-vehicle device.

[0054] The following details steps S110 to S140 of the Bluetooth automatic connection method of this embodiment.

[0055] Step S110: When detecting a Bluetooth demand signal sent by the application, start the Bluetooth connection and determine whether the Bluetooth connection is the first connection.

[0056] Specifically, in this embodiment, the user equipment 10 detects a Bluetooth demand signal sent by an application program, starts a Bluetooth connection, scans for connectable Bluetooth signals, and detects the Bluetooth signal strength of the connectable Bluetooth signals. When the detected Bluetooth signal strength is within a preset signal strength range, it is determined whether the Bluetooth connection is a first connection: it is determined whether there is connection information of the vehicle-mounted device 20 to which the connectable Bluetooth signal belongs in the Bluetooth connection list, that is, it is determined whether the vehicle-mounted device 20 to which the connectable Bluetooth signal belongs has established a Bluetooth connection with the user equipment 10. If not, it is determined that the Bluetooth connection is a first connection; if so, it is determined that the Bluetooth connection is not a first connection.

[0057] Step S120: When the Bluetooth connection is a first connection, obtain an authentication code from the vehicle-mounted device 20 through a non-Bluetooth wireless network with a pre-established connection.

[0058] In this embodiment, the user equipment 10 and the vehicle-mounted device 20 pre-establish non-Bluetooth wireless networks such as Wi-Fi, GPRS, 2G / 3G / 4G / 5G wireless networks.

[0059] The vehicle-mounted device 20 pre-stores the authentication code of the user equipment 10, where the authentication code of the user equipment 10 is an authentication code exclusive to the user equipment 10 provided by the manufacturer of the user equipment 10. The authentication code of the user equipment 10 is pre-stored in the vehicle-mounted device 20. When the user equipment 10 requests to establish Bluetooth communication with the vehicle-mounted device 20, through a non-Bluetooth wireless network such as Wi-Fi, GPRS, 2G / 3G / 4G / 5G wireless networks pre-established with the vehicle-mounted device 20, the authentication code exclusive to the user equipment 10 in the vehicle-mounted device 20 is sent to the user equipment 10.

[0060] In this embodiment, the authentication code exclusive to the user equipment 10 can be directly stored in the vehicle-mounted device 20 or stored in the cloud server of the vehicle-mounted device 20. When the user equipment 10 requests to establish Bluetooth communication with the vehicle-mounted device 20, the vehicle-mounted device 20 downloads and obtains the corresponding authentication code from the cloud server.

[0061] Step S130: Authenticate the Bluetooth connection initiated by the application program based on the authentication code.

[0062] Specifically, in this embodiment, as Figure 3 shown, the authenticating the Bluetooth connection initiated by the application program based on the authentication code includes:

[0063] Step S131: Match the obtained authentication code with the local authentication code pre-stored in the user equipment 10;

[0064] Step S132: When the authentication code matches the local authentication code pre-stored in the user device 10, authenticate the application as a trustworthy application;

[0065] Step S133: After authenticating the application as a trustworthy application, confirm that the Bluetooth connection initiated by the application is a secure connection.

[0066] In this embodiment, the authentication code obtained from the vehicle-mounted device 20 is compared with the local authentication code of the user device 10 to determine that the application initiating the Bluetooth connection is a secure and trustworthy application, and then confirm that the Bluetooth connection initiated by the application is a secure connection.

[0067] Step S140: After the Bluetooth connection initiated by the application passes the authentication, confirm that the Bluetooth connection initiated by the application is a secure connection, and establish a Bluetooth connection between the user device 10 and the vehicle-mounted device 20.

[0068] In this embodiment, the application that issues the Bluetooth demand signal is authenticated as a trustworthy application through the authentication code, establishing a higher-level trust relationship for the Bluetooth connection, and realizing automatic authentication without the need for user access confirmation when establishing the Bluetooth connection for the first time.

[0069] In addition, in this embodiment, the Bluetooth automatic connection method further includes: in response to the connection between the user device 10 and the vehicle-mounted device 20, prompting that the user device 10 and the vehicle-mounted device 20 have been connected; wherein, the prompting methods include: controlling the user device 10 to light up the screen, pop-up window prompt, voice prompt, or a combination of one or more of them.

[0070] For example, after the user device 10 and the vehicle-mounted device 20 are connected, the user is prompted that the user device 10 and the vehicle-mounted device 20 are connected by controlling the user device 10 to light up the screen. For example, when the vehicle head unit and the mobile phone Bluetooth connection is successful, the mobile phone lock screen display is triggered to light up the screen.

[0071] For another example, after the user device 10 and the vehicle-mounted device 20 are connected, a message box can also be popped up under the lock screen of the user device 10 for a pop-up window prompt. For example, when the vehicle head unit and the mobile phone Bluetooth connection is successful, the message “Bluetooth connection has been established” is popped up on the mobile phone screen.

[0072] In addition, after the user device 10 and the vehicle-mounted device 20 are connected, it can also be prompted by voice or vibration. For example, when the vehicle head unit and the mobile phone Bluetooth connection is successful, the mobile phone plays: “Bluetooth connection has been established”.

[0073] Therefore, in the Bluetooth automatic connection method of this embodiment, when the user device 10 and the vehicle-mounted device 20 establish a Bluetooth connection for the first time, authentication is automatically performed, achieving the effect of seamless authentication and effectively improving the user experience.

[0074] In this embodiment, an audio signal is transmitted to the vehicle-mounted device 20 through the established Bluetooth connection, and a video signal is transmitted to the vehicle-mounted device 20 through the non-Bluetooth wireless network.

[0075] In this embodiment, as Figure 4 shown, the application program of the user device 10 is a screen mirroring application program. When the video stream of the user device 10 is cast to the vehicle-mounted device 20, the audio signal is transmitted through the Bluetooth network, and the video signal is transmitted through a non-Bluetooth wireless network such as Wi-Fi. After the user device 10 and the vehicle-mounted device 20 establish a connection through Wi-Fi and need to establish a Bluetooth connection, the Bluetooth automatic connection method of this embodiment is automatically used to establish a Bluetooth connection between the user device 10 and the vehicle-mounted device 20. Then, an audio signal is transmitted to the vehicle-mounted device 20 through the established Bluetooth connection, and a video signal is transmitted to the vehicle-mounted device 20 through the non-Bluetooth wireless network.

[0076] This embodiment also provides a Bluetooth automatic connection method, which is applied to the vehicle-mounted device 20. Figure 5 The following shows the principle flowchart when the Bluetooth automatic connection method of this embodiment is applied to the vehicle-mounted device 20. As Figure 5 shown, when the Bluetooth automatic connection method is applied to the vehicle-mounted device 20, it includes the following steps:

[0077] Step S210: When detecting a Bluetooth demand signal sent by the application program mirrored from the user device 10 in the vehicle-mounted device 20, obtain the pre-stored authentication code of the user device 10.

[0078] Among them, the vehicle-mounted device 20 pre-stores the authentication code of the user device 10, or the vehicle-mounted device 20 obtains the authentication code of the user device 10 pre-stored in the cloud server from the cloud server.

[0079] Step S220: Send the authentication code to the user device 10 for the user device 10 to authenticate the Bluetooth connection.

[0080] Step S230: After the user device 10 authenticates the Bluetooth connection, establish a connection with the user device 10.

[0081] That is to say, in this embodiment, when the application program initiating the Bluetooth connection needs to be authenticated, it can obtain the authentication code (certification code) from the in-vehicle device 20 or the cloud server, authenticate the application program as a secure application program, and the user device 10 will authenticate the Bluetooth connection initiated by the application program as a secure connection. If it is not a connection initiated by a third-party application program, fast authentication can be performed.

[0082] As Figure 6 shown, this embodiment also provides a Bluetooth automatic connection device 100, which is applied to the user device 10. The Bluetooth automatic connection device 100 includes: a first connection detection module 110, an authentication code acquisition module 120, an authentication module 130, and a connection confirmation module 140.

[0083] In this embodiment, when the first connection detection module 110 detects a Bluetooth demand signal sent by the application program, it starts the Bluetooth connection and determines whether the Bluetooth connection is a first connection.

[0084] In this embodiment, when the Bluetooth connection is a first connection, the authentication code acquisition module 120 obtains the authentication code from the in-vehicle device 20 through a non-Bluetooth wireless network with a pre-established connection.

[0085] In this embodiment, the authentication module 130 authenticates the Bluetooth connection initiated by the application program based on the authentication code.

[0086] In this embodiment, after the Bluetooth connection initiated by the application program passes the authentication, the connection confirmation module 140 confirms that the Bluetooth connection initiated by the application program is a secure connection and establishes a Bluetooth connection between the user device 10 and the in-vehicle device 20.

[0087] In this embodiment, the technical features and implementation principles of the Bluetooth automatic connection device 100 applied to the user device 10 are the same as those of steps S110 to S140 in the Bluetooth automatic connection method applied to the user device 10 in this embodiment.

[0089] In this embodiment, when the authentication code acquisition module 210 detects a Bluetooth demand signal sent by the application program projected by the user device 10 in the in-vehicle device 20, it acquires the pre-stored authentication code of the user device 10;

[0090] In this embodiment, the authentication code sending module 220 sends the authentication code to the user device 10 for the user device 10 to authenticate the Bluetooth connection;
