Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in further detail below.
As an example, the intelligent networked vehicle is basically configured with a Bluetooth digital vehicle key function and supports a multi-Bluetooth positioning function. Under the condition, the user does not need to take out the mobile terminal to unlock and lock the vehicle by clicking the button, and only needs to enter or leave the detection range of the vehicle by the mobile terminal to unlock and lock the vehicle, so that keyless entry is realized. The function of the digital key polling can be positioned through the area of the low-power Bluetooth, noninductive unlocking is carried out, and the vehicle using convenience of a user is effectively improved.
However, in the above process, the owner of the vehicle authorizes the corresponding bluetooth digital key to family or friends, and when the users are near the vehicle at the same time at a certain time, the owner cannot know who mobile terminal is connected to the vehicle-mounted bluetooth of the vehicle-mounted terminal at the current time, and cannot establish bluetooth communication connection between the own mobile terminal and the vehicle-mounted terminal, so that the control of the vehicle function cannot be realized. Moreover, the effective communication distance of the bluetooth can reach dozens of meters, which is more likely to cause the appearance of such scenes, so that the vehicle terminal can not effectively manage the bluetooth connection of different mobile terminals.
In view of the above, one of the core invention points of the embodiments of the present invention is that a main bluetooth and a slave bluetooth are set in a vehicle-mounted terminal, a mobile terminal can initiate a forced connection request of the bluetooth through the slave bluetooth, and the vehicle-mounted terminal disconnects a communication connection between the main bluetooth and a connected terminal according to the forced connection request, so as to create an exclusive and time-limited connection channel for a new mobile terminal, and only allow the mobile terminal initiating the forced connection request to establish a communication connection with the main bluetooth within a certain time, thereby implementing the forced connection of a user terminal through the cooperation between the main bluetooth and the slave bluetooth, and establishing a bluetooth connection according to the connection request of the terminal, thereby greatly improving the flexibility of the vehicle-mounted bluetooth connection, being applicable to a scenario of multi-bluetooth connection, and improving the vehicle experience of a user.
Specifically, referring to fig. 1, a flowchart of steps of a multi-terminal based bluetooth connection method provided in an embodiment of the present invention is shown, where the method at least relates to a vehicle-mounted terminal, a first terminal, and a second terminal, where the vehicle-mounted terminal includes a master bluetooth and at least one slave bluetooth, and the vehicle-mounted terminal is in communication connection with the first terminal based on the master bluetooth, and specifically includes the following steps:
in the embodiment of the present invention, the vehicle-mounted terminal may include a master bluetooth and at least one slave bluetooth, where the master bluetooth may be a vehicle-mounted bluetooth in communication connection with the mobile terminal, and after the mobile terminal establishes communication connection with the master bluetooth, part of functions of the vehicle may be controlled, such as unlocking the vehicle, controlling a vehicle-mounted air conditioner, controlling a vehicle window, and the like; the slave bluetooth may include a first slave bluetooth capable of transmitting a connectable non-directional broadcast, for which it may establish a communication connection with the mobile terminal, and a second slave bluetooth capable of transmitting a non-connectable non-directional broadcast, for which the mobile terminal may not establish a communication connection with the second slave bluetooth although it may receive the broadcast it transmits, and may be used to request disconnection of the communication connection between the master bluetooth and the mobile terminal.
In an example, referring to fig. 2, a schematic diagram of a vehicle-mounted bluetooth provided in an embodiment of the present invention is shown, where a vehicle-mounted terminal may be configured with a vehicle owner bluetooth and a plurality of vehicle slave bluetooth, a mobile terminal may only perform vehicle control communication with the vehicle owner bluetooth through an application program, such as unlocking, turning on and off an air conditioner, flashing lights, and whistling of a vehicle, and the remaining slave bluetooth is mainly used for a positioning algorithm (i.e., bluetooth polling function), for example, the slave bluetooth may include slave bluetooth a, slave bluetooth B, and slave bluetooth C, where:
1. connectable non-directional broadcasts may be sent from bluetooth a. Before broadcasting from Bluetooth A, Bluetooth acquires a mobile phone Bluetooth MAC address currently connected with Bluetooth A from a main BLE through an LIN bus of a vehicle, and fills the MAC address in a specific field (6 bytes) of broadcasting data of the Bluetooth A;
2. the slave Bluetooth A supports a transient connection communication function and is connected with a timeout mechanism, and the holding time of each link is 20 seconds;
3. the broadcast types sent from bluetooth B and from bluetooth C are non-directional broadcasts that are not connectable.
And, the master bluetooth and the slave bluetooth communicate with each other through the LIN line, including the above-mentioned interactive communication therebetween.
It should be noted that, in the embodiment of the present invention, the slave bluetooth is the first slave bluetooth, and the mobile terminal performs data interaction with the first slave bluetooth to establish a bluetooth communication connection with the master bluetooth.
The first terminal and the second terminal can be mobile terminals used by different users, and are terminals that perform authentication in the vehicle-mounted terminal, that is, the first terminal and the second terminal are terminals that are authorized by the vehicle-mounted terminal and can control functions of the vehicle. For the first terminal, the terminal which establishes communication connection with the main Bluetooth of the vehicle-mounted terminal at present can be used; for the second terminal, it may be a terminal that does not currently establish a bluetooth connection with the in-vehicle terminal, but wants to establish a bluetooth connection, and the invention is not limited to this.
In a specific implementation, the second terminal may run a corresponding application program, the content displayed on the graphical user interface of the second terminal may at least include the application interface of the application program, the application interface may include a bluetooth connection control, the second terminal obtains a second terminal address of the second terminal in response to a selection operation acting on the bluetooth connection control, generates a forced connection instruction corresponding to the second terminal address, then generates a first connection request for the vehicle-mounted terminal by using the second terminal address and the forced connection instruction, and sends the first connection request to the vehicle-mounted terminal.
Optionally, the bluetooth connection control may be an interactive control of "forcibly connect to the vehicle-mounted bluetooth" in the application interface, and when the user clicks the control, the second terminal may actively establish a communication connection with the slave bluetooth of the vehicle-mounted terminal and send a first connection request to the second terminal, so as to establish a communication connection with the master bluetooth. Specifically, after the user clicks the bluetooth connection control, the bluetooth communication connection with the slave bluetooth of the vehicle-mounted terminal is established, the mac address of the user is obtained, the forced connection instruction corresponding to the mac address is generated, then the first connection request (such as the bluetooth forced connection request) is generated by the user and the slave bluetooth of the vehicle-mounted terminal, and the first connection request is sent to the slave bluetooth of the vehicle-mounted terminal, so that the vehicle-mounted terminal performs corresponding data processing.
102, the vehicle-mounted terminal receives the first connection request based on the slave Bluetooth and transmits the first connection request to the master Bluetooth;
in a specific implementation, the vehicle-mounted terminal may receive the first connection request from the slave bluetooth, disconnect the communication connection between the slave bluetooth and the second terminal, then parse the first connection request, obtain the second terminal address and the forced connection instruction, and transmit the second terminal address and the forced connection instruction to the master bluetooth.
In one example, the application program run by the second terminal may actively connect the slave bluetooth a of the in-vehicle terminal according to the operation of the user, and after the connection is successful, send the forced connection instruction and the mac address of the second terminal to the slave bluetooth a, and after the connection is successful, the second terminal disconnects the bluetooth communication connection with the slave bluetooth a. The vehicle-mounted terminal sends the forced connection instruction and the mac address of the second terminal to the master Bluetooth through the LIN line of the vehicle through the slave Bluetooth A, so that the vehicle-mounted terminal can perform corresponding data processing and establish Bluetooth communication connection with the second terminal.
103, the vehicle-mounted terminal disconnects the communication connection between the main Bluetooth and the first terminal according to the forced connection instruction;
in a specific implementation, the in-vehicle terminal may execute a forced connection instruction to disconnect the communication connection between the main bluetooth and the first terminal, and then establish a time-limited communication channel for the second terminal by using the address of the second terminal and a preset connection time threshold.
Alternatively, the connection time threshold may be a time threshold set for bluetooth forced connection, and the master bluetooth of the vehicle-mounted terminal may only perform establishment of bluetooth connection with the mobile terminal initiating the bluetooth forced connection within the time threshold, such as the second terminal in the embodiment of the present invention.
In an example, after receiving the forced connection instruction sent from bluetooth a, the master bluetooth may actively disconnect the current bluetooth communication connection with the first terminal, and establish a time-limited communication channel for the second terminal based on the mac address of the second terminal and a preset connection time threshold, for example, within 2 minutes, the master bluetooth of the vehicle-mounted terminal only establishes communication connection with the second terminal, and after 2 minutes, the master bluetooth of the vehicle-mounted terminal is in an idle state, and any mobile terminal may establish bluetooth communication connection therewith.
And 104, the vehicle-mounted terminal receives a second connection request sent by the second terminal based on the main Bluetooth and establishes communication connection with the second terminal.
In a specific implementation, the vehicle-mounted terminal receives a second connection request sent by the second terminal through the main bluetooth, where the second connection request may include a bluetooth connection instruction, and the vehicle-mounted terminal establishes a communication connection between the main bluetooth and the second terminal by using the bluetooth connection instruction and a previously established time-limited communication channel, so as to implement function control of the second terminal on the vehicle.
In one example, after the main bluetooth of the vehicle-mounted terminal disconnects the bluetooth communication connection with the first terminal, the vehicle-mounted terminal can be limited to establish the bluetooth communication connection only with the second terminal within a certain time. In the process, the user can refresh the application interface through the application interface of the second terminal, or wait for a period of time (if the second terminal starts the bluetooth polling function), the second terminal can initiate a bluetooth connection request to the main bluetooth, and after the main bluetooth of the vehicle-mounted terminal receives the bluetooth connection request, the bluetooth communication connection with the second terminal can be established, so that the second terminal can perform corresponding bluetooth vehicle control operations, such as unlocking and locking of a vehicle, window switching, cooling of a vehicle-mounted air conditioner and the like.
In addition, after the second terminal establishes the bluetooth communication connection with the main bluetooth, the vehicle-mounted terminal can acquire the communication connection time between the main bluetooth and the second terminal, and if the vehicle-mounted terminal detects that the communication connection time meets a preset threshold, the communication connection between the main bluetooth and the second terminal is disconnected. The preset threshold value can be a threshold value corresponding to the connection time threshold value, for example, assuming that the preset threshold value is 2 minutes, after the connection time between the second terminal and the main bluetooth reaches 2 minutes, the main bluetooth can actively disconnect the bluetooth communication connection with the second terminal, and the bluetooth forced connection is finished, so that the bluetooth communication connection is established with other mobile terminals, thereby greatly improving the flexibility of vehicle-mounted bluetooth connection, being applicable to a scene of multi-bluetooth connection, and improving the vehicle-using experience of a user.
In an optional embodiment of the present invention, the content displayed on the gui of the second terminal at least includes an application interface of an application program, and the application interface includes a mode selection control, so that the second terminal may further obtain broadcast data sent by the vehicle-mounted terminal from the bluetooth in response to a selection operation performed on the mode selection control, where the broadcast data includes a first terminal address of the first terminal, and then obtain terminal information of the first terminal from a preset server by using the first terminal address, and display the terminal information, so that a user to whom the second terminal belongs notifies the first terminal to disconnect a communication connection with the main bluetooth based on the terminal information.
In an example, the application interface displayed on the image user interface of the second terminal may include a mode selection control, for example, a "vehicle-mounted bluetooth connection preemption mode" control, so that when the user clicks the control, the application program may execute a bluetooth connection preemption function, and an information acquisition control is provided in the application interface, through which terminal information (for example, a mobile phone number, etc.) of the first terminal currently establishing communication connection with the main bluetooth of the vehicle-mounted terminal may be acquired. Specifically, the second terminal may respond to a selection operation applied to the information acquisition control, acquire broadcast data sent by the in-vehicle terminal through the bluetooth a, parse the broadcast data to obtain a target field expressed by 31 bytes, and extract the mac address of the first terminal currently connected to the main bluetooth of the in-vehicle terminal from the target field. Then the second terminal can inquire the mobile phone number corresponding to the mac address from the background server through the mobile internet, and obtain the last four digits of the mobile phone number corresponding to the first terminal returned by the background server, then the corresponding information is displayed in the application interface, so that the user of the second terminal can obtain the terminal of which the terminal connected with the vehicle-mounted terminal is by browsing the corresponding information, further, the user to which the terminal belongs can be directly contacted, so that the corresponding user can control the first terminal to actively disconnect the Bluetooth communication connection with the vehicle-mounted terminal, the second terminal can conveniently carry out the Bluetooth connection with the vehicle-mounted terminal, by acquiring the terminal information of the mobile terminal which is currently connected, the Bluetooth connection between the terminal and the vehicle-mounted terminal is controlled, the flexibility that on-vehicle bluetooth connects can be improved, the scene that can be applicable to many bluetooth and connect has improved user's experience with the car.
