Detailed Description

Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numbers in different drawings refer to the same or similar elements, unless otherwise indicated. The implementations described in the following exemplary examples are not representative of all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with some aspects of the present disclosure as detailed in the accompanying claims.

Before introducing the pairing method, device, storage medium and system of the fob key of the disclosure, an application scenario of the disclosure is first described.

A fob key, i.e., a smart key, is generally a device that allows a user to perform functions such as opening/closing a door and starting a vehicle without inserting a separate key or operating a start button. The fob key may include, for example, an NFC (Near Field Communication ) fob key, a bluetooth fob key, or the like.

Taking the bluetooth fob key as an example, a user may autonomously complete pairing of the vehicle and the bluetooth fob key after lifting the vehicle. Fig. 1 is a pairing flow chart of a bluetooth fob key shown in the present disclosure, and referring to fig. 1, the pairing flow of the bluetooth fob key includes:

The vehicle owner operates the vehicle through a central control large screen of the vehicle to enable the vehicle to enter a pairing mode; in addition, the owner can press the key switch on the bluetooth fob key, makes bluetooth fob key enter the pairing state.

In this way, the vehicle can search for a bluetooth device to be connected by bluetooth search, such as searching for the bluetooth fob key and initiating a connection. After the vehicle and the bluetooth fob key find each other, the vehicle establishes a bluetooth connection with the bluetooth fob key. The bluetooth fob key may then pair with the vehicle. For example, the vehicle may exchange a vehicle key related key with a bluetooth fob key over a bluetooth channel, thereby completing the pairing.

After this process, the user can unlock the vehicle through the bluetooth fob key, thereby using the vehicle.

It should be noted that, in order to ensure the safety of the vehicle, to avoid the vehicle from randomly attempting to connect to an external bluetooth device, it is generally possible to set up: after a user operates the vehicle center control large screen to enable the vehicle to enter a pairing mode, the vehicle can search for a Bluetooth fob key.

However, this arrangement makes it necessary for the user to have the ability to unlock the vehicle and access the vehicle cabin before bluetooth fob key pairing can take place. For example, in some scenarios, to perform a fob key pairing, the user needs to hold another agreed type of vehicle key to unlock the vehicle and enter the vehicle after the unlock, and set the vehicle into pairing mode in the center screen. In addition, the fob key needs to be maintained within the vehicle during pairing. Therefore, the pairing steps of the fob key are complicated, and the pairing process is not flexible enough.

For this reason, the present disclosure provides a pairing method of a fob key, which is applied to a fob key. Fig. 2 is a flowchart of a pairing method of a fob key according to an exemplary embodiment of the disclosure, and referring to fig. 2, the method includes:

in step S21, a pairing code of a vehicle owner and a first key of a vehicle key of the vehicle are acquired from a terminal of the vehicle owner.

For example, the fob key may be connected to the owner's terminal, such as a Bluetooth connection. After connection with the terminal of the vehicle owner, the pairing code and the first key may be obtained from the terminal.

As in one possible embodiment, step S21 may include:

an information acquisition request is sent to the terminal, wherein the information acquisition request is used for acquiring a pairing code and a first secret key of the vehicle;

and receiving the pairing code and the first key sent by the terminal.

For example, in one possible implementation, the pairing code and the first key are preset in the service end of the vehicle and the vehicle. For example, the pairing code and the first key may be generated during the vehicle production process, and the pairing code and the first key may be preset in the vehicle and the server. Or, the pairing code and the first key may be generated at any time before the fob key is connected and paired with the vehicle, and the pairing code and the first key may be preset in the vehicle and the server.

The pairing code and the first key can be generated by the server side or by a related trusted device, and the device for generating the first key and the device for generating the pairing code can be the same or different. In addition, the first key may be a symmetric key or an asymmetric key based on the provision of the car key protocol, which is not limited in the present disclosure.

In this way, after the fob key sends the information acquisition request to the terminal, the terminal may acquire the first key and the pairing code from the server. For example, the terminal may obtain its own associated vehicle, such as by a vehicle enterprise application. In this way, the terminal can send a request to the server through information of the vehicle (which information can be stored in a storage medium of the terminal, such as an identification of the vehicle, production data, etc.). The server side can query the pairing code and the first key of the vehicle according to the information of the vehicle and return the pairing code and the first key to the terminal.

In an embodiment, the terminal may also obtain the user associated with itself, for example, the user associated with itself is obtained through the vehicle enterprise application program, which may be a login user in the vehicle enterprise application program. In this way, the terminal may send a request to the server through the information of the user (these information may be stored in a storage medium of the terminal, such as a user name, an identity identifier, an account name, etc.), thereby obtaining the pairing code and the first key. The server side can query the vehicle associated with the user according to the information of the user, acquire the pairing code and the first key of the vehicle, and return the pairing code and the first key to the terminal.

In a possible implementation manner, the first key is preset in a service end of the vehicle and the vehicle, the first key is obtained from the service end by the terminal, and the pairing code is generated by the terminal and is synchronized into the vehicle through the service end, so that the preset pairing code is obtained.

For example, the first key may be generated during the vehicle production process, and the first key may be preset in the vehicle and the server. The first key may be generated by the server or by a related trusted device.

In this way, after the fob key sends the information acquisition request to the terminal, the terminal may acquire the first key from the server. For example, the terminal may obtain its own associated vehicle, such as by a vehicle enterprise application. In this way, the terminal can send a request to the server through the information of the vehicle. The server side can inquire a first key of the vehicle according to the information of the vehicle and return the first key to the terminal.

In an embodiment, the terminal may also obtain the user associated with itself, for example, by using a vehicle enterprise application. In this way, the terminal can send a request to the server through the information of the user, thereby obtaining the first key. The server side can query the vehicle associated with the user according to the information of the user, acquire the first key of the vehicle and return the first key to the terminal.

Regarding the pairing code, the pairing code may be generated by a terminal, for example, and the generation manner may be generated randomly or based on the provision of the relevant car key protocol. After the terminal generates the pairing code, the pairing code can be sent to a server, and the server sends the pairing code to a vehicle to obtain a pairing code preset in the vehicle. In addition, the terminal can also send the pairing code generated by the terminal and the first key acquired from the server to the fob key.

In one possible implementation manner, the pairing code and the first key are preset in a service end of the vehicle, the vehicle and the terminal, and the pairing code and the first key are acquired from a terminal storage space by the terminal. Thus, after the fob key sends the information obtaining request to the terminal, the terminal may obtain the first key and the pairing code from the terminal storage space, and send the first key and the pairing code to the fob key.

Referring to fig. 2, in step S22, in the case where the vehicle is not unlocked, a first connection is made with the vehicle based on the pairing code.

Under the condition that the pairing code is consistent with the pairing code preset in the vehicle, the vehicle is connected with the fob key for the first time. Because the corresponding pairing code is preset in the vehicle, the device without the pairing code cannot establish connection with the vehicle. In this way, the vehicle in the above scheme has the ability to identify a legitimate fob key. In this case, unlike the related art in which the vehicle is not connected to other devices when not unlocked, the vehicle in the embodiment of the present disclosure may also receive a connection request when not unlocked.

As one example, a vehicle may receive a connection request of a fob key, which may include a pairing code. In this way, the vehicle can determine whether the pairing code is identical to a pairing code preset in the vehicle. In the case that the pairing code is inconsistent with a pairing code preset in the vehicle, the vehicle can reject the connection request; and under the condition that the pairing code is consistent with the pairing code preset in the vehicle, the vehicle can make a first connection with the fob key through the connection request.

In step S23, if the connection with the vehicle is successful, the first pairing with the vehicle is performed based on the first key.

For example, in one possible implementation, the first pairing with the vehicle based on the first key includes:

and sending a pairing request to the vehicle based on the first key, wherein the pairing request comprises verification information of the first key, and the pairing request is used for requesting the vehicle to verify the first key according to a second key of a preset vehicle key in the vehicle and the verification information of the first key, and pairing with the fob key under the condition that the verification is passed.

As an example, if the first key is a symmetric key of the vehicle key, the verification information of the first key may include an encryption result of verification data based on the symmetric key, and the verification data may be any data selected based on a requirement. In this way, the vehicle can decrypt the encryption result according to the first key in the vehicle. And when the decryption is successful, determining that the fob key has the first key and accepting the fob key, thereby completing pairing.

As an example, in some scenarios the first key is a public key of an asymmetric key pair of a car key, the authentication information of the first key may include an encryption result of authentication data based on the public key. In this way, the vehicle can decrypt the encryption result according to the private key in the vehicle. And when the decryption is successful, determining that the fob key has the public key and accepting the fob key, thereby completing pairing.

It should be noted that the process of pairing the vehicle with the fob key may be based on the provision of the vehicle key agreement, which is not limiting of the present disclosure.

In this way, the fob key does not need to unlock the vehicle when first paired with the vehicle. Therefore, the pairing mode can omit the steps of unlocking the vehicle and entering the vehicle by the user, so that the use experience of the user can be improved. For example, the user does not need to carry the relevant vehicle unlocking tool to unlock the vehicle, nor does the user need to enter a pairing mode in which the vehicle is manually turned on.

Based on the same inventive concept, the present disclosure also provides a pairing method of a fob key, which is applied to a terminal, where the terminal may be a terminal related to an embodiment of the present disclosure, and the terminal may be presented in a form of a mobile phone, a tablet device, a wearable device, or the like. Fig. 3 is a flowchart of a pairing method of a fob key according to an exemplary embodiment of the disclosure, and referring to fig. 3, the method includes:

in step S31, a pairing code of a vehicle to be paired with the fob key and a first key of a vehicle key of the vehicle are acquired.

For example, the fob key may be connected to the terminal, such as a bluetooth connection. After connection with a terminal, an information acquisition request may be sent to the terminal. The terminal may acquire a pairing code of a vehicle to be paired with the fob key and a first key of a vehicle key of the vehicle in response to the information acquisition request. Here, for example, the vehicle with which the terminal is associated may be regarded as the vehicle to be paired with the fob key.

In implementing step S31, in one possible implementation manner, the pairing code and the first key are preset in the service end of the vehicle and the vehicle, and the obtaining the pairing code of the vehicle to be paired with the fob key and the first key of the vehicle key includes:

in response to receiving an information acquisition request sent by the fob key, determining a vehicle associated with the terminal, and obtaining the vehicle to be paired with the fob key;

and acquiring the pairing code and the first secret key from the server based on the information of the vehicle.

In one possible implementation manner, the pairing code and the first key are preset in the service end of the vehicle, the vehicle and the terminal, and the obtaining the pairing code of the vehicle to be paired with the fob key and the first key of the vehicle includes:

and acquiring the pairing code and the first key from a terminal storage space based on the information of the vehicle.

In one possible implementation manner, the first key is preset in a service end of the vehicle and the vehicle, and the obtaining a pairing code of the vehicle to be paired with the fob key and the first key of the vehicle includes:

acquiring the first key from the server based on the information of the vehicle;

and generating a pairing code, and synchronizing the pairing code into the vehicle through the server to obtain a preset pairing code in the vehicle.

The embodiment of the terminal for obtaining the pairing code of the vehicle and the first key has been described in detail in the above embodiment of step S21, and for brevity of description, the disclosure is not repeated here.

In step S32, the pairing code and the first key are transmitted to the fob key.

The pairing code is used for enabling the fob key to be connected with the vehicle for the first time based on the pairing code under the condition that the vehicle is not unlocked. Under the condition that the pairing code is consistent with a pairing code preset in the vehicle, the vehicle is connected with the fob key for the first time; the first key is used for first pairing with the vehicle based on the first key under the condition that the fob key is successfully connected with the vehicle.

The embodiments of the first connection and the first pairing of the fob key and the vehicle have been described in detail in the above embodiments of step S22 and step S23, and for brevity of description, the disclosure is not repeated here.

Based on the same inventive concept, the disclosure also provides a pairing method of the fob key, which is applied to a vehicle. The vehicle may be a vehicle as referred to in embodiments of the present disclosure. Fig. 4 is a flowchart of a pairing method of a fob key according to an exemplary embodiment of the disclosure, and referring to fig. 4, the method includes:

in step S41, a connection request of a fob key is received, the connection request including a pairing code, the fob key acquiring the pairing code from a terminal of a vehicle owner and a first key of a vehicle key of the vehicle.

The implementation of the fob key to obtain the pairing code and the first key is described with reference to the embodiment of fig. 2, and the disclosure is not repeated here.

In step S42, in the case where the vehicle is not unlocked and the pairing code matches the pairing code preset in the vehicle, the first connection is made with the fob key.

Because the corresponding pairing code is preset in the vehicle, the device without the pairing code cannot establish connection with the vehicle. In this way, the vehicle in the above scheme has the ability to identify a legitimate fob key. In this case, unlike the related art in which the vehicle is not connected to other devices when not unlocked, the vehicle in the embodiment of the present disclosure may also receive a connection request when not unlocked.

In step S43, if the connection with the fob key is successful, the first pairing is performed with the fob key based on the first key.

For example, in one possible implementation, the first pairing with the fob key based on the first key includes:

receiving a pairing request of a fob key, wherein the pairing request comprises verification information of the first key;

verifying the first key according to a second key of a preset vehicle key in the vehicle and verification information of the first key;

and if the verification is passed, the pair is matched with the fob key.

As an example, the first key is a symmetric key of the car key, and the authentication information of the first key may include an encryption result of authentication data based on the symmetric key. In this way, the vehicle can decrypt the encryption result according to the first key in the vehicle. And when the decryption is successful, determining that the fob key has the first key and accepting the fob key, thereby completing pairing.

Based on the same inventive concept, the disclosure also provides a pairing method of the fob key. Fig. 5 is a flowchart of a pairing method of a fob key according to an exemplary embodiment of the disclosure, and referring to fig. 5, the method includes:

the cloud service of the vehicle factory pre-generates a Bluetooth fob key related key pair, and presets a vehicle side key to the vehicle in a production line filling mode in the vehicle production process. The cloud service of the vehicle factory can be, for example, a service end related in the embodiment of the disclosure.

The user purchases the vehicle and the bluetooth fob key. When the user expects to pair the Bluetooth fob keys, the key switch of the Bluetooth fob keys can be pressed to enable the Bluetooth fob keys to enter the pairing state. The user can also enable the owner mobile phone equipment to enter a collaborative pairing state through a related APP button in a car factory APP (application program) on the owner mobile phone equipment after the identity authentication is completed.

Like this, car owner cell-phone equipment car factory APP can look for the bluetooth fob key that waits to connect through bluetooth. If the car owner mobile phone equipment car factory APP finds the Bluetooth fob key, the Bluetooth connection is established with the Bluetooth fob key.

After the Bluetooth connection is established, the Bluetooth fob key can apply for a Bluetooth pairing code capable of completing Bluetooth pairing with the vehicle and a vehicle key capable of completing key pairing with the vehicle to the mobile phone equipment of the vehicle owner.

After receiving the application of the Bluetooth fob key, the car owner mobile phone equipment car factory APP applies for the Bluetooth pairing code and the car key to car factory cloud service.

After verifying that the request of the vehicle owner mobile phone equipment vehicle factory APP is correct, the vehicle factory cloud service sends the Bluetooth pairing code and the vehicle key to the vehicle owner mobile phone equipment vehicle factory APP.

After receiving the Bluetooth pairing code and the car key issued by the cloud service of the car owner, the car factory APP of the car owner mobile phone equipment sends the Bluetooth pairing code and the car key to a Bluetooth fob key through Bluetooth connection.

In this way, the bluetooth fob key successfully obtains a bluetooth pairing code that can complete bluetooth pairing with the vehicle and a vehicle key that can complete key pairing with the vehicle. In this way, the owner can hold the Bluetooth fob key close to the vehicle for first connection and first pairing with the vehicle.

Referring to a flow chart of a first connection and first pairing of a fob key with a vehicle shown in fig. 6, the flow includes:

the car owner bluetooth fob key is close to the vehicle, and bluetooth scanning and bluetooth discovery processes between the vehicle and the bluetooth fob key are carried out based on a bluetooth pairing mode agreed by a car manufacturer.

The Bluetooth fob key initiates a Bluetooth pairing request to the vehicle based on the acquired Bluetooth pairing code, the Bluetooth pairing request being used to request establishment of a Bluetooth communication channel. The vehicle may respond to the bluetooth pairing request, such as establishing a bluetooth communication channel with the bluetooth fob key if the bluetooth pairing code is consistent with a bluetooth pairing code preset in the vehicle.

After the Bluetooth communication channel is established, the Bluetooth fob key sends a vehicle key to the vehicle to facilitate the vehicle to verify the Bluetooth fob key. For example, the vehicle may verify the car key sent by the bluetooth fob key from a preset car key. After verification is correct, the vehicle can accept the Bluetooth fob key;

in this way, the bluetooth fob key completes the first pairing procedure with the vehicle.

According to the scheme, the vehicle factory cloud service is introduced, and can serve as a generator and an authorizer of the vehicle key. The scheme also introduces a vehicle factory APP to bridge a communication channel between the vehicle factory cloud service and the Bluetooth fob key. In this way, the vehicle key acquisition procedure of the bluetooth fob key can be completed without the participation of the vehicle. And moreover, after the Bluetooth fob key is acquired and approaches to the vehicle, mutual trust between the Bluetooth fob key and the vehicle can be automatically completed, the whole process can be performed without sense, and the use experience of a user can be improved.

In addition, since the corresponding bluetooth pairing code is preset in the vehicle, the device without the bluetooth pairing code cannot establish connection with the vehicle. In this way, the vehicle in the above scheme has the capability of primarily identifying a legitimate fob key. When the vehicle is connected with the Bluetooth fob key for the first time, the Bluetooth fob key has a vehicle key, so that the vehicle can further verify the validity of the fob key through the vehicle key.

Thus, the vehicle can ensure the safety of the connected Bluetooth equipment by combining the Bluetooth pairing code and the double verification of the vehicle key. Therefore, in the above-described embodiment, the vehicle may no longer have the setting of "the vehicle must be manually operated by the user to enter the external bluetooth device accepted state" in the conventional scheme.

Therefore, the fob key in the above scheme can be connected and paired with the vehicle for the first time without unlocking the vehicle. In this way, the fob key pairing process does not require the user to hold an additional agreed type of vehicle key into the cabin nor to keep the fob key in the vehicle. Therefore, the scheme can promote the flexibility of pairing the Bluetooth fob keys and simplify the operation steps of users.
