Detailed Description
The core of the invention is to provide a method for updating the electronic key of the vehicle, which can realize the transfer of the authority of the vehicle under the condition that the original mobile terminal is lost, avoid the economic loss of users caused by the theft of the vehicle and property in the vehicle and improve the safety of the vehicle.
In order that those skilled in the art will better understand the disclosure, the invention will be described in further detail with reference to the accompanying drawings and specific embodiments. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 1, fig. 1 is a schematic flowchart of a method for updating an electronic key of a vehicle by a mobile terminal according to an embodiment of the present application, where the method may include:
s11: and sending an update key request containing the user identification to the cloud server, and downloading the encryption information from the cloud server.
The encryption information at least comprises a new key generated by the cloud server according to the user identification.
Specifically, for each vehicle, before starting to be put into use, a user account needs to be registered and a corresponding password needs to be set. This operation is similar to the operation of registering Taobao account and WeChat account which are common at present. The APP controlling the vehicle end can be downloaded on the mobile terminal, or the user account can be logged in through a network page, and then the user account can be logged in, wherein each user account corresponds to one vehicle.
S12: and establishing communication connection with the vehicle end within the preset distance range, and forwarding the encrypted information to the vehicle end so that the vehicle end can update the current key stored by the vehicle end according to the encrypted information.
For the current vehicle, the function of communication networking with a cloud server is not available, but the function of short-distance bluetooth communication connection and NFC communication connection with a mobile terminal is available, but the precondition of the communication connection is that the distance between the vehicle and the mobile terminal cannot be too far.
In addition, for mobile terminals such as mobile phones, a WiFi hotspot is opened to provide network connection for electronic devices in a short distance, and therefore a communication device capable of connecting the WiFi hotspot can be configured for a vehicle end, and communication connection with the mobile terminal is achieved.
S13: and receiving vehicle end updating success information sent by the vehicle end, and sending the vehicle end updating success information to the cloud server.
S14: and receiving a new key sent by the cloud server so as to control the vehicle terminal through the new key.
For the present application, the key update mainly includes two aspects, that is, the key update in the vehicle side, and the key update of the mobile terminal, and the mobile terminal can only realize the control of the vehicle side after both the vehicle side and the mobile terminal are successfully updated.
However, for the current vehicle end, a networking function is not configured, that is, direct information interaction with the cloud server cannot be performed, and the vehicle end needs to update the key and needs to obtain a new key from the cloud server. After the key update at the vehicle end is completed, the mobile terminal is updated.
In order to ensure the safety of information interaction between the cloud server and the mobile terminal, the cloud server encrypts the information containing the new key forwarded to the vehicle end by the mobile terminal to obtain encrypted information, and the vehicle end can decrypt the encrypted information after receiving the encrypted information to obtain the new key in the encrypted information, so that the key of the vehicle end is updated.
And after the vehicle side key is updated, the cloud server sends a new key to the mobile terminal, and the new key is also sent to the mobile terminal after being encrypted.
The method and the device have the advantages that the mobile terminal is used as a medium to update keys in the vehicle end and the mobile terminal, so that even if a user loses the mobile terminal, new contact can be established between the new mobile terminal and the vehicle end, and the authority of controlling the vehicle end is transferred to another mobile terminal from one mobile terminal, so that the situation that property in the vehicle or the vehicle is lost under the situation that the mobile terminal is lost is avoided, and property safety of the user is guaranteed.
As mentioned above, the communication connection between the mobile terminal and the vehicle terminal is performed based on short-range wireless communication such as bluetooth and NFC, and does not require networking operation. That is to say, when the mobile terminal controls the vehicle end, it is not necessary to log in the relevant APP account, as long as the keys between the vehicle end and the mobile terminal can be matched with each other. If the user can control the mobile terminal of the vehicle to be lost and the user cannot find a new mobile terminal for key updating in a short time, in this case, the lost mobile terminal still has a control authority over the vehicle, so that the vehicle has a potential safety hazard.
For this reason, in another embodiment of the present application, an available time limit may also be set for the keys of the mobile terminal and the vehicle. For example, 3 days. Under normal conditions, the mobile terminal automatically performs the information interaction with the cloud server and the vehicle end every 3 days to update the keys of the vehicle end and the mobile terminal.
When it needs to be explained, similar to the currently common mode of logging in a mobile terminal by WeChat and QQ, the APP with the key changed in the application can only log in one mobile terminal. When a user logs in a user account by using a first mobile terminal, the mobile terminal sends a user name and a password input by the user and mobile terminal information to a cloud server, the cloud server generates a user identifier and sends the user identifier to the mobile terminal after the user name and the password are authenticated to be correct, and the mobile terminal is identified and verified through the user identifier when information interaction with the cloud server is subsequently carried out on the mobile terminal. For the user, when the mobile terminal logs in the account, the user name and the password do not need to be input again, similar to the method that after WeChat logs in only by using a mobile phone for the first time, the user can log in the account without quitting the login and opening the APP every time, and the user name and the password do not need to be input again.
When the mobile terminal of the user is lost, after the user logs in the user account with the new mobile terminal, the cloud server generates a new user identifier and sends the new user identifier to the mobile terminal, the user identifier of the original mobile terminal is invalid, if the user logs in the user account again through the original mobile terminal, the user needs to input the user name and the password again on the original mobile terminal, and after the original mobile terminal obtains the new user identifier again, the key updating operation can be carried out. The operation mode can effectively ensure the safety of the user account, and avoid the condition that the lost mobile terminal is operated by others to change the keys of the vehicle terminal and the mobile terminal.
To sum up, the process of vehicle electronic key renewal in this application can go on under two kinds of circumstances, and first is:
and when the use time of the current key reaches the preset time, sending a key updating request.
Secondly, the following steps:
when the user identification is inconsistent with the user identification stored in the cloud server, displaying an input login user account interface;
sending the received user name and password and the mobile terminal information to a cloud server;
after the user name and the password pass the verification, receiving a user identifier newly generated by the cloud server;
and sending a key updating request containing the newly generated user identification to the cloud server.
Under the two conditions, the mobile terminal can realize the starting of the key updating program of the mobile terminal and the vehicle terminal, and further the safety of vehicle property is ensured.
In the following, the mobile terminal vehicle electronic key updating device provided by the embodiment of the present invention is introduced, and the mobile terminal vehicle electronic key updating device described below and the mobile terminal vehicle electronic key updating method described above may be referred to correspondingly.
Fig. 2 is a block diagram of a mobile terminal device for updating an electronic key of a vehicle according to an embodiment of the present invention, where the mobile terminal device for updating an electronic key of a vehicle according to fig. 2 may include:
an update request module 110, configured to send an update key request including a user identifier to a cloud server, and download encryption information from the cloud server, where the encryption information at least includes a new key generated by the cloud server according to the user identifier;
the first transmission module 120 is configured to establish communication connection with a vehicle end within a preset distance range, and forward the encrypted information to the vehicle end, so that the vehicle end updates a current key stored in the vehicle end according to the encrypted information;
the second transmission module 130 is configured to receive vehicle-side update success information sent by the vehicle side, and send the vehicle-side update success information to the cloud server;
and a key updating module 140, configured to receive the new key sent by the cloud server, so as to control the vehicle end through the new key.
Optionally, in another specific embodiment of the present application, the method may further include:
the update request module 110 is specifically configured to send the key update request when the usage duration of the current key reaches a preset duration.
Optionally, in another specific embodiment of the present application, the update request module 110 may further include:
the first login unit is used for displaying an input login user account interface when the user identification is inconsistent with the user identification stored in the cloud server;

the identification receiving unit is used for receiving a user identification newly generated by the cloud server after the user name and the password are verified;
and the updating request unit is used for sending an updating key request containing the newly generated user identification to the cloud server.
The mobile terminal vehicle electronic key updating device of this embodiment is used to implement the foregoing mobile terminal vehicle electronic key updating method, so that the specific implementation manner of the mobile terminal vehicle electronic key updating device can be seen in the foregoing embodiment section of the mobile terminal vehicle electronic key updating method, and details are not described herein again.
As shown in fig. 3, fig. 3 is a schematic flowchart of a method for updating an electronic key of a vehicle by a vehicle end according to an embodiment of the present application, where the method specifically includes:
s21: establishing communication connection with a mobile terminal within a preset distance range, and receiving encrypted information downloaded by the mobile terminal from a cloud server;
s22: acquiring a new key in the encrypted information according to the encrypted information;
s23: updating the current key stored currently according to the new key;
s24: and sending the vehicle end updating success information to the cloud server through the mobile terminal so that the mobile terminal can obtain a new key from the cloud server.
As described above, the vehicle end uses the mobile terminal as a medium for transmitting data to obtain the encryption information for updating the key from the cloud server, so that the key can be updated. Specifically, as shown in fig. 4, fig. 4 is a schematic diagram of the encryption information provided in the embodiment of the present application. The encryption information may comprise the information shown in fig. 4 in the present application. The encryption information may specifically be a 14-bit string representation. Each character represents different information.
The first bit of information is the zone bit information, the vehicle end decodes after receiving the encrypted information, the zone bit information at the first byte is read, and if the information is 1, the encrypted information is used for updating the key.
The second position information is the vehicle key information, namely a new key.
The third bit of information is the old car key information, namely the current key.
The fourth to sixth pieces of information are information on timeliness of the key.
The seventh to ninth pieces of information are user-related information.
The tenth to thirteenth bits are vehicle-side information.
The fourteenth bit is the bluetooth communication key.
When the key updating process is actually carried out, only the contents of the third bit and the fourth bit are used for verifying the contents of the encrypted information, and after the verification is successful, the key updating is carried out based on the contents of the second bit. That is, the S22 may specifically include:
decrypting the encrypted information to obtain a new key, a current key and a communication key which are at least contained in the encrypted information;
and verifying the current key and the communication key, and when the verification is passed, updating the current key stored currently according to the new key.
In this embodiment, the cloud server transmits information to the vehicle end in an encrypted form, so that the security of the information is ensured, and the content of the encrypted information is further verified, so that the security of information updating is further ensured.
In addition, when the vehicle side verifies the encrypted information, the current key before updating, that is, the old key, needs to be verified, and therefore, the current keys stored in the vehicle side, the cloud server and the mobile terminal must be kept consistent to update the keys. As shown in the foregoing, the mobile terminal needs to update the key after the key at the vehicle end is updated, so that the situations that the key at the vehicle end is not updated successfully, the key at the mobile terminal is not updated successfully, and the old keys at the vehicle end and the mobile terminal are inconsistent can be effectively avoided.
