fig. 1 is a flowchart of a method for conveniently connecting an automobile bluetooth key according to an embodiment of the invention.
Detailed Description
Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to like or similar elements or elements having like or similar functions throughout. The embodiments described below by referring to the drawings are illustrative only and are not to be construed as limiting the invention.
The invention provides an embodiment of a convenient connection method for an automobile Bluetooth key, specifically, as shown in fig. 1, the method comprises the following steps:
step S1, when Bluetooth key connection is carried out for the first time, a user mobile terminal establishes Bluetooth connection with a vehicle end through a digital key APP;
specifically, a mobile terminal digital key APP is opened to establish connection with a vehicle-end Bluetooth, bluetooth safe connection pairing is completed, and LTK (long-term password) is generated; further, after the first digital key authentication is successful (including standard protocol ICCE or CCC authentication, or private Bluetooth authentication), the mobile phone terminal stores long-term password information (LTK).
Step S2, the user mobile terminal sends Bluetooth key connection information to a vehicle end for storage;
specifically, the bluetooth key connection information includes: long-term password, bluetooth MAC information, key ID, expiration date, etc. Further, the Bluetooth controller of the vehicle end uses the HID profile, and the user mobile terminal marks the vehicle end as an HID device.
Step S3, when the user mobile terminal is subsequently connected with the vehicle-end Bluetooth key, the user mobile terminal is actively connected with the vehicle-end;
the active connections described herein may include: the user mobile terminal opens a digital key APP to perform active connection; or when the Bluetooth of the mobile phone is in an on state and the mobile phone enters a Bluetooth broadcasting range (for example, 20 meters) of the vehicle end, the mobile phone system is actively connected with the Bluetooth of the vehicle end, specifically, the mobile phone system reads corresponding LTK information from the locally stored data and automatically connects with the HID equipment (namely, the vehicle end).
S4, the vehicle end performs information checking (LTK information and Bluetooth MAC information), and when checking is passed and within the validity period, connection success is determined;
regarding the expiration date, the following schemes are provided herein for reference: when the information is calibrated, the calibration times are recorded and used as the service life of the Bluetooth key, specifically, when the information is calibrated for each Bluetooth connection, the calibration is recorded once until the calibration times are larger than a preset time threshold, namely the characterization exceeds the effective period, at the moment, the vehicle end actively deletes the previously stored Bluetooth key connection information, prompts a user to carry out Bluetooth safety pairing again and reports the Bluetooth key connection information to the background, and therefore the Bluetooth connection safety can be improved.
Step S5, after connection is successful, bluetooth positioning calculation is performed by acquiring Bluetooth signal intensity to judge the position of a key, so that a sensorless control vehicle (unlocking, starting and the like) is realized, the time for operating a mobile phone and opening an APP can be effectively saved, and the verification is performed by adopting LTK information, so that the verification process is simple and the time is shorter.
Finally, it may be further added that, in order to avoid the risk of losing or replacing the mobile terminal of the user, the method further includes: binding key owner information with a corresponding vehicle in advance, and sending an instruction for deleting current Bluetooth key connection information to a vehicle end after receiving loss report information of a user.
In summary, the main design concept of the invention is that when the user completes the connection between the user mobile terminal and the bluetooth of the vehicle end once and uses the bluetooth key again, the user mobile terminal activated by bluetooth is automatically connected with the vehicle end in the bluetooth area of the vehicle, and the non-inductive unlocking and locking are realized, so that the user is not required to take out the mobile phone and connect with the bluetooth of the vehicle end through the operation of the digital key APP, the connection time of the user mobile terminal and the bluetooth key is greatly shortened, and the use is convenient and quick.
