first embodiment

Referring to FIG. 1, the present invention provides a method for synchronizing the state of a door lock based on a mobile phone screen, including:

Step S1, when the mobile phone is less than the preset distance from the vehicle TBOX3, the vehicle TBOX3 sends an authentication request to the mobile phone, and when the vehicle TBOX3 receives the mobile phone information fed back by the mobile phone 1, the mobile phone information is authenticated, and if the authentication is passed, then confirm the above. Mobile phone 1 is the user's mobile phone, go to step S2;

In step S2, the vehicle TBOX3 sends a request for “whether to control the door” to the mobile phone 1 through the Internet of Vehicles server 2. If yes, the Internet of Vehicles server 2 will determine the control signal to send to the vehicle TBOX3, and go to step S3; otherwise, the door switch is controlled by the original car key .

Among them, in the request information "whether to control the door" sent by the Internet of Vehicles server 2, the selection operation does not affect the screen status of the mobile phone 1. For example, when mobile phone 1 locks the screen, mobile phone 1 will turn on the screen when it receives the request information, and "Yes" and "No" will be displayed on the screen of mobile phone 1. The user clicks one of the options to operate. After unlocking, the communication between the mobile phone 1 and the Internet of Vehicles server 2 is completed through the radio frequency module in the mobile phone 1 .

In addition, the vehicle TBOX3 includes a positioning unit for measuring the distance between the mobile phone 1 and the vehicle, and the positioning system adopted by the positioning unit is GPS, AGPS, Wifi or cell identification. Cell ID locates one of the positioning systems. Of course, the monitoring range of the positioning unit is the preset distance, and the preset distance can be adjusted according to the actual situation.

Among them, within the preset distance between the mobile phone 1 and the vehicle TBOX3, the vehicle TBOX3 sends an authentication request to the mobile phone 1, and the specific operation steps are as follows:

The positioning unit detects whether there is a mobile phone 1 around the vehicle; if there is a mobile phone 1 around the vehicle, the vehicle TBOX3 sends an authentication request to the mobile phone 1;

After receiving the authentication request, the mobile phone 1 feeds back the mobile phone information to the vehicle TBOX3 for authentication. If the sent mobile phone information is the same as the mobile phone information preset in the vehicle TBOX3, the authentication passes; otherwise, the authentication fails.

Further, before step S1, it is necessary to match the user's mobile phone 1 with the vehicle TBOX3 to establish a unique security matching relationship. After the matching relationship is established, the mobile phone information is stored in the vehicle TBOX3 as the preset mobile phone information, and the TBOX device identification number and mobile phone information are stored by the vehicle. TBOX3 is sent to the Internet of Vehicles server 2 for storage.

Further, the specific operations of establishing a matching relationship between the user's mobile phone 1 and the vehicle TBOX3 include:

S11, the vehicle TBOX3 receives a connection request that the user's mobile phone 1 actively sends to it and includes the user's mobile phone information, where the user's mobile phone information includes the user's mobile phone number and a Bluetooth address. A mobile client can be installed on the user's mobile phone 1, the mobile phone number and Bluetooth address of the user's mobile phone 1 can be entered in the mobile client, and the mobile phone number and Bluetooth address can be sent to the vehicle TBOX3 through the mobile client. You can also turn on the Bluetooth of the mobile phone 1, and after searching the Bluetooth of the vehicle TBOX3, click the Bluetooth address of the vehicle TBOX3 to send the mobile phone information.

S12, the vehicle TBOX3 detects whether the mobile phone information has been saved, and if it has not been saved, it will perform an adaptation operation, and if it has been saved, it will be directly connected.

In addition, when the vehicle TBOX3 detects that the Bluetooth address has not been saved, it indicates that the user's mobile phone 1 is connected to the vehicle TBOX3 for the first time, and the adaptation operation needs to be completed, please refer to Figure 2, including:

S111, the vehicle TBOX3 provides a mobile phone registration interface to the user through the vehicle-machine interface, and the mobile phone registration interface includes a mobile phone number input box and a verification code input box;

S112, the user successfully inputs the user's mobile phone number on the registration interface, the vehicle TBOX3 sends the user's mobile phone number and the TBOX device identification number to the Internet of Vehicles server 2, and the Internet of Vehicles server 2 sends the verification code to the vehicle TBOX3 and the user's mobile phone 1;

S113, the user completes the input of the verification code on the registration interface, and if the entered verification code is consistent with the verification code received by the vehicle TBOX3, the Bluetooth adaptation is successful. After the Bluetooth adaptation is successful, the establishment of the only secure matching relationship between the mobile phone 1 and the vehicle TBOX3 is completed.

The Bluetooth adaptation may be that the vehicle TBOX3 provides the vehicle Bluetooth matching number to the user; the Bluetooth matching number of the vehicle TBOX3 has been set at the factory and belongs to a fixed matching number. The user enters the Bluetooth matching number on the mobile phone 1 to complete the Bluetooth adaptation, and the Bluetooth address of the mobile phone 1 is saved in the vehicle TBOX3. It is also possible to input the pairing code of the same number on the car machine and the mobile phone 1 at the same time to complete the connection.

The Bluetooth address of mobile phone 1 is composed of three parts: LAP (24-bit address low-end part), UAP (8-bit address high-end part) and NAP (16-bit meaningless address part). Among them, NAP and UAP are the only ones of the manufacturer. The identification code must be assigned to different manufacturers by the Bluetooth authority, while the LAP is freely assigned by the manufacturer. Therefore, for a certain type of mobile phone 1, the NAP and UAP of all individuals are fixed, and the variable is LAP. The LAP has a total of 24 bits. Generally speaking, the manufacturer will allocate addresses from 0 to 2 during manufacture. 24 to the power to ensure the distinction of addresses between individuals. However, when there are too many products and the 24th power of 2 is used up, or there is a problem when writing the address, the address will be reused. However, due to the large number of products, in general, although the The bluetooth address may be the same, but the probability of two identical bluetooth addresses appearing in the same scenario is very small; in addition, even if the same bluetooth address appears in the same scenario, the mobile phone numbers matching each bluetooth address cannot be the same Therefore, the combination of mobile phone number + mobile phone Bluetooth address is used to establish a unique security matching relationship during the adaptation operation, which prevents other mobile phones 1 from tampering with the connection relationship between the vehicle TBOX3 and the mobile phone 1 at will. Of course, when the user changes mobile phone 1 or number, and sends a connection request to the car, it belongs to the first connection because it is different from the previously saved mobile phone information, and the matching relationship between mobile phone 1 and vehicle TBOX3 is re-established. The information is replaced with the existing cell phone information.

Step 3, the vehicle TBOX receives the corresponding door control signal obtained by the car networking server identifying the current screen state of the mobile phone, and the vehicle TBOX performs an operation on the vehicle door lock according to the vehicle door control signal.

In the step S3, the screen state of the mobile phone 1 is the open state and the screen lock state respectively, and the opening and closing of the vehicle door are controlled in turn; the Internet of Vehicles server 2 sends the screen state of the mobile phone 1 to the vehicle TBOX3. When the initial state corresponds to the screen state of mobile phone 1, the door state remains unchanged; when the initial state of the door detected by the vehicle TBOX3 is contrary to the screen state of mobile phone 1, the door state is changed.

In the process of controlling the door state through the screen state of the mobile phone 1, the original key remote control function can still be used at the same time. Of course, the original key remote control function can also be set to be invalid during this process. The failure operation can be as follows: In step S2, when After the mobile phone 1 confirms "control the door", the vehicle TBOX3 sends a key failure signal to the vehicle controller 37, the vehicle controller 37 controls the electronic switch module 38 to disconnect, and the door lock ECU and the receiver of the original vehicle remote control door lock system are connected. The connection between the two is disconnected, making the original car key remote control function invalid; when the recovery condition is reached, the original car key remote control function is disabled.

The recovery process of the original key function is as follows: in one case, in step S3, when the screen of the mobile phone 1 is in the locked screen state, when the door is opened, the user uses the password, gesture or fingerprint to unlock the mobile phone 1. If the unlocking fails, The mobile phone 1 sends the unlocking failure information to the vehicle TBOX3 through the IoV server 2, and the vehicle controller 37 receives the unlocking failure information through the vehicle TBOX3. The connection between the ECU and the receiver is closed, so that the original key remote function is restored. Another situation is that in step S3, after the vehicle TBOX3 opens the door, the vehicle controller 37 controls the electronic switch module 38 to close through the door open signal, the connection between the door lock ECU and the receiver is closed, and the original car key remote control function recover.
