Detailed Description
Embodiments of the present invention are described below with reference to the drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of, and enabling description for, those skilled in the art. It will be apparent, however, to one skilled in the art, that the present invention may be practiced without some of these specific details. Furthermore, it should be understood that the invention is not limited to specific described embodiments. Rather, any combination of the features and elements described below is contemplated as carrying out the invention, whether or not they relate to different embodiments. Thus, the following aspects, features, embodiments and advantages are merely illustrative and are not considered elements or limitations of the claims except where explicitly recited in a claim.
Referring now to fig. 1, a flow chart of a method for vehicle launch with a mobile smart device is shown in accordance with an embodiment of the present invention.
Firstly, when the whole vehicle is in a power-off state, the mobile intelligent device initiates a Bluetooth connection request to a BLE module (the BLE module can be a separate module or integrated in a vehicle-mounted T-BOX) of the vehicle according to the operation of a user on a user interface. The BLE module carries out identity authentication on the mobile intelligent device and establishes BLE connection with the mobile intelligent device after the identity authentication is passed. The identity authentication of the mobile intelligent device can be realized by adopting any appropriate identity authentication mode in the prior art.
Then, the mobile intelligent device sends a start authorization authentication request to the BLE module according to the operation of the user on the user interface, and the BLE module sends the start authorization authentication request to a vehicle body control unit of the vehicle through a CAN (Controller Area Network) bus.
Then, the vehicle body control unit carries out start authorization authentication on the BLE module. Specifically, the body control unit may generate a random code, calculate the random code based on an encryption algorithm (e.g., AES128), and send the random code to the BLE module, which calculates the random code based on the same encryption algorithm (e.g., AES128), and send the calculation result to the body control unit. And the vehicle body control unit compares the calculation result obtained by the vehicle body control unit with the calculation result from the BLE module, and if the two calculation results are the same, the starting authorization authentication is considered to be successful.
If the start authorization authentication is successful, the vehicle body control unit allows a user of the vehicle to start the vehicle (such as opening a door or an engine of the vehicle), and transmits a result of successful start authorization to the BLE module, and the BLE module transmits a result of successful start authorization to the mobile intelligent device. And the mobile intelligent equipment displays the result of successful vehicle starting authorization to the user.
After the start authorization authentication is successful, the vehicle body control unit may set therein a flag indicating a start authorization state, the flag being valid for a preset period or before the start authorization is cancelled. During the period that the zone bit is effective, a user holding the mobile intelligent device can directly start the vehicle through the in-vehicle starting switch.
Referring now to fig. 2, a flow chart of a method for implementing vehicle locking by means of a mobile smart device is shown in accordance with an embodiment of the present invention.
Firstly, when the whole vehicle is in a starting authorization state, the mobile intelligent device initiates a Bluetooth connection request to a BLE module of the vehicle according to the operation of a user on a user interface. The BLE module carries out identity authentication on the mobile intelligent device and establishes BLE connection with the mobile intelligent device after the identity authentication is passed. The identity authentication of the mobile intelligent device can be realized by adopting any appropriate identity authentication mode in the prior art.
Then, the mobile intelligent device sends a whole vehicle locking authentication request to the BLE module according to the operation of the user on the user interface, and the BLE module sends the whole vehicle locking authentication request to a vehicle body control unit of the vehicle.
Then, the vehicle body control unit performs locking authentication on the BLE module. Specifically, the body control unit may generate a random code, calculate the random code based on an encryption algorithm (e.g., AES128), and send the random code to the BLE module, which calculates the random code based on the same encryption algorithm (e.g., AES128), and send the calculation result to the body control unit. And the vehicle body control unit compares the calculation result obtained by the vehicle body control unit with the calculation result from the BLE module, and if the two calculation results are the same, the locking authentication is considered to be successful.
If the locking authentication is successful, the vehicle body control unit locks the vehicle (for example, locks the door and the engine of the vehicle) and cancels the starting authorization of the user holding the mobile intelligent device, and sends the results that the vehicle locking is successful and the starting authorization is cancelled to the BLE module, and the BLE module sends the results that the vehicle locking is successful and the starting authorization is cancelled to the mobile intelligent device. And the mobile intelligent device displays the results that the vehicle is locked successfully and the starting authorization is cancelled to the user.
After the start authorization is cancelled, a flag bit which is arranged in the vehicle body control unit and represents the start authorization state is invalid. After the zone bit became invalid, the user who holds mobile intelligent equipment can not directly start the vehicle through the start switch in the vehicle.
In the invention, a complete scheme for realizing vehicle starting and locking by means of the mobile intelligent equipment is provided, thereby filling the blank of the prior art.
In the invention, the identity authentication is carried out on the mobile intelligent equipment by utilizing the vehicle-mounted BLE module, and the start authorization authentication and the locking authentication are carried out on the BLE module by utilizing the vehicle body control unit, so that the interference of an illegal message source to the communication process is prevented, and the safety of the communication process is improved.
It should be noted that the above description is only an example and not a limitation of the present invention. In other embodiments of the invention, the method may have more, fewer, or different steps, and the order, inclusion, or functional relationship between the steps may be different from that described and illustrated. For example, generally, steps may be combined into a single step, or a single step may be split into multiple steps. For a person skilled in the art, the sequence of the steps is not changed without creative efforts and is within the protection scope of the invention.
The technical solution of the present invention may be substantially implemented or partially implemented in the prior art, or all or part of the technical solution may be implemented in a software product, which is stored in a storage medium and includes several instructions to enable a computer device (which may be a personal computer, a server, or a network device) or a processor or a microcontroller to execute all or part of the steps of the method according to the embodiments of the present invention.
