Detailed ways

The core of the present invention is to provide a method for updating a vehicle electronic key, so that when the original mobile terminal is lost, the transfer of the authority to control the vehicle can be realized, so as to avoid the theft of the vehicle and the property in the vehicle, causing the economic loss of the user, and improving the safety of the vehicle. safety.

In order to make those skilled in the art better understand the solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are only some, but not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts 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 a vehicle electronic key by a mobile terminal according to an embodiment of the present application, and the method may include:

S11: Send an update key request including the user ID to the cloud server, and download encrypted information from the cloud server.

The encrypted information at least includes a new key generated by the cloud server according to the user identifier.

Specifically, before each vehicle is put into use, it is necessary to register a user account and set a corresponding password. This operation is similar to the more common operation of registering a Taobao account and a WeChat account. The APP that controls the vehicle end can be downloaded on the mobile terminal, or the login of the user account can be realized through the web page, and then the login of the user account can be realized, and each user account corresponds to a vehicle.

S12: Establish a communication connection with the vehicle terminal within a preset distance range, and forward the encrypted information to the vehicle terminal, so that the vehicle terminal can update the current key stored in the vehicle terminal according to the encrypted information.

For the current vehicle, it does not have the function of communication and networking with the cloud server, but it has the function of short-range Bluetooth communication connection and NFC communication connection with the mobile terminal, but the precondition of this communication connection is The distance between the vehicle and the mobile terminal cannot be too far.

In addition, for mobile terminals such as mobile phones, it also has the ability to enable WiFi hotspots to provide network connections for electronic devices within a short distance. Therefore, in this application, a communication device capable of connecting to WiFi hotspots can also be configured for the vehicle end, thereby realizing and Communication connection between mobile terminals.

S13: Receive the vehicle-end update success information sent by the vehicle end, and send the vehicle-end update success information to the cloud server.

S14: Receive a new key sent by the cloud server, so as to control the vehicle end through the new key.

For this application, the key update mainly lies in two aspects, one is the key update in the vehicle, and the other is the key update of the mobile terminal. When both the vehicle and the mobile terminal are successfully updated, the mobile terminal can Realize the control of the vehicle end.

However, for the current vehicle end, the networking function is not configured, that is to say, it is impossible to directly exchange information with the cloud server, and the vehicle end needs to obtain a new key from the cloud server to update the key. Therefore, in this application Using the mobile terminal as the medium of information transmission, after obtaining the encrypted information from the cloud server through the mobile terminal, it is forwarded to the vehicle end, and the vehicle end updates the key according to the encrypted information. Moreover, after the key update on the vehicle side is completed, the mobile terminal is updated.

In order to ensure the security of information exchange between the cloud server and the mobile terminal, the cloud server encrypts the information containing the new key that is forwarded to the vehicle by the mobile terminal to obtain encrypted information. After receiving the encrypted information, the vehicle can The encrypted information is decrypted to obtain a new key in the encrypted information, thereby realizing the update of the vehicle-side key.

And after the vehicle-side key update is completed, when the cloud server sends the new key to the mobile terminal, it is also encrypted and sent to the mobile terminal.

In this application, the mobile terminal is used as the medium to realize the update of the key in the vehicle terminal and the mobile terminal, so that even if the user loses the mobile terminal, he can re-use a new mobile terminal and establish a new connection between the vehicle terminal, thereby making The authority to control the vehicle end is transferred from one mobile terminal to another mobile terminal to avoid the loss of the vehicle or the property in the vehicle when the mobile terminal is lost, which is beneficial to ensure the safety of the user's property.

As mentioned above, the communication connection between the mobile terminal and the vehicle terminal is based on short-range wireless communication such as Bluetooth and NFC, and does not require network operation. That is to say, when the mobile terminal controls the vehicle terminal, it does not need to log in to the relevant APP account, as long as the keys between the vehicle terminal and the mobile terminal can be matched with each other. Then, if the user can control the mobile terminal of the vehicle is lost, but the user cannot find a new mobile terminal to update the key in a short period of time, in this case, the lost mobile terminal still has control authority over the vehicle side, so that the vehicle side exists. Security risks.

To this end, in another specific embodiment of the present application, an available time period may also be set for the keys at the mobile terminal and the vehicle end. For example, 3 days. Under normal circumstances, the mobile terminal automatically exchanges the information in the above embodiment with the cloud server and the vehicle terminal every 3 days to realize the key update between the vehicle terminal and the mobile terminal.

It should be noted that, similar to the currently commonly used methods of logging in to a mobile terminal via WeChat and QQ, the APP for key replacement in this application can only be logged in on one mobile terminal. When the user uses the first mobile terminal to log in to the user account, the mobile terminal will send the user name and password entered by the user and the mobile terminal information to the cloud server. After the cloud server verifies that the user name and password are correct, a user ID will be generated and sent to the mobile terminal. The terminal, when the mobile terminal subsequently exchanges information with the cloud server, the mobile terminal is identified and verified by the user ID. For the user, every time the mobile terminal logs in to the account, there is no need to enter the user name and password again, similar to WeChat, which only needs to log in with the mobile phone for the first time, as long as the user does not log out, every time the APP is opened, there is no need to enter the user name and password again. You can achieve the same login.

When the user's mobile terminal is lost, after the user logs in to the user account with the new mobile terminal, the cloud server will generate a new user ID and send it to the mobile terminal, and the original user ID of the mobile terminal will become invalid. When the mobile terminal logs in to the user account, the user needs to input the user name and password on the original mobile terminal again. After the original mobile terminal obtains a new user ID, the key update operation can be performed. This operation mode can effectively ensure the security of the user account, and avoid the situation where the lost mobile terminal is operated by others to change the keys of the vehicle and the mobile terminal.

To sum up, the process of updating the vehicle electronic key in this application will be carried out in two cases, the first is:

When the usage duration of the current key reaches the preset duration, an update key request is sent.

The second is:

When the user ID is inconsistent with the user ID stored in the cloud server, the interface for entering the login user account is displayed;

Send the received username and password, and mobile terminal information to the cloud server;

After the user name and password are verified, receive the user ID newly generated by the cloud server;

Send an update key request containing the newly generated user ID to the cloud server.

In the above two cases, the mobile terminal can realize the activation of the key update program at the mobile terminal and the vehicle end, thereby ensuring the safety of the vehicle property.
