[0040] The technical solutions provided by the embodiments of this disclosure may include the following beneficial effects:

[0041] The vehicle broadcasts a key seed generated by itself. Based on this key seed and the key sent by the mobile terminal, the vehicle calculates a first Bluetooth pairing code. The mobile terminal, upon receiving the broadcast key seed, calculates a second Bluetooth pairing code based on the key seed and a pre-obtained key. It then initiates Bluetooth pairing with the vehicle using this second pairing code. If the first and second pairing codes match, a Bluetooth connection is established between the mobile terminal and the vehicle. This prevents mobile terminals without the key from resolving the second pairing code and thus from establishing a Bluetooth connection. This prevents unauthorized external devices from attempting to connect via Bluetooth and from occupying the vehicle's Bluetooth communication channel for extended periods. It also avoids situations where a mobile terminal carrying a Bluetooth digital car key fails to pair with the vehicle's Bluetooth, resulting in the inability to unlock the vehicle using the Bluetooth car key information. When the Bluetooth connection is successful, the mobile terminal sends Bluetooth car key information to the vehicle via Bluetooth, allowing control of the vehicle after successful verification. This improves the stability of vehicle control via Bluetooth car key information, optimizes the overall security of Bluetooth car key information, and enhances the user experience.

[0042] It should be understood that the above general description and the following detailed description are exemplary and explanatory only, and are not intended to limit this disclosure. Attached Figure Description

[0050] Figure 7 This is a functional block diagram of a vehicle illustrating an exemplary embodiment. Detailed Implementation

[0051] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0052] It should be noted that all actions involving the acquisition of signals, information, or data in this application are carried out in compliance with the relevant data protection laws and policies of the country where the application is located, and with the authorization granted by the owner of the relevant device.

[0053] Before introducing the vehicle control method, device, mobile terminal, vehicle, and storage medium provided in this disclosure, the relevant technologies in this scenario are first explained. Firstly, the authenticated vehicle owner's mobile terminal requests a sharing link for a Bluetooth digital car key from the cloud server. The cloud server sends this sharing link to the vehicle owner's mobile terminal. The vehicle owner's mobile terminal can then share this sharing link with other terminals via SMS or other means. Furthermore, both other terminals and the vehicle owner's mobile terminal can obtain the Bluetooth digital car key from the cloud server based on this sharing link. When the vehicle is in a normal parked and powered-on state, it broadcasts Bluetooth information to the surrounding space, including plaintext... The vehicle owner's mobile device or other terminal can parse the received Bluetooth information to obtain the plaintext Bluetooth pairing code corresponding to the vehicle. Based on this pairing code, the vehicle owner can initiate Bluetooth pairing with the vehicle's Bluetooth and send a Bluetooth digital car key to the vehicle's Bluetooth after completing the pairing. Upon receiving the Bluetooth digital car key from the vehicle owner's mobile device or other terminal, the vehicle owner can parse the Bluetooth digital car key and authenticate its trustworthiness through relevant security policies. If the Bluetooth digital car key is verified to be legitimate, the Bluetooth digital car key usage process is completed.

[0054] During this process, the vehicle's Bluetooth broadcasts a plaintext Bluetooth pairing code, guiding the owner's mobile device or other terminals to easily pair and connect with the vehicle's Bluetooth, thus establishing the basic Bluetooth communication channel. The received Bluetooth digital car key then performs relevant security policy authentication, ensuring the secure use of the Bluetooth digital car key. However, due to the limited number of Bluetooth communication channels (typically four), unauthorized external devices may attempt to pair and connect via Bluetooth, effectively occupying the vehicle's Bluetooth communication channels for an extended period. This can prevent the terminal carrying the Bluetooth digital car key from completing the pairing and connection, resulting in the failure to unlock the vehicle using the Bluetooth digital car key.

[0055] Therefore, this disclosure provides a vehicle control method. A mobile terminal without the key cannot parse the second Bluetooth pairing code and cannot establish a Bluetooth connection with the vehicle. This prevents unauthorized external devices from connecting via Bluetooth and from occupying the vehicle's Bluetooth communication channel for extended periods. It also avoids situations where a mobile terminal carrying a Bluetooth digital car key cannot complete Bluetooth pairing with the vehicle, leading to failure to unlock the vehicle using Bluetooth car key information. This improves the stability of vehicle control via Bluetooth car key information, optimizes the overall security of Bluetooth car key information, and enhances the user experience of using Bluetooth car key information.

[0056] Figure 1 This is a flowchart illustrating a vehicle control method according to an exemplary embodiment, such as... Figure 1As shown, this vehicle control method is applied to a mobile terminal and includes the following steps.

[0057] In step S11, in response to receiving the key seed broadcast by the vehicle, the second Bluetooth pairing code corresponding to the mobile terminal is calculated based on the key seed and the pre-obtained key.

[0058] In this embodiment of the disclosure, when a mobile terminal carrying a key enters the broadcast range of a vehicle, it can receive the key seed broadcast by the vehicle via broadcast. Although other mobile terminals, such as unauthorized mobile terminals, can also receive the key seed broadcast by the vehicle, these unauthorized mobile terminals do not carry the key and therefore cannot calculate a Bluetooth pairing code that matches the first Bluetooth pairing code from the key seed.

[0059] The mobile terminal can use a preset, symmetric key generation algorithm to calculate the second Bluetooth pairing code using the key seed and the key.

[0060] The first Bluetooth pairing code is calculated by the vehicle based on a key seed generated by the vehicle and the acquired key. The key seed is generated randomly by the vehicle at a preset period. This key seed can be randomly generated by the vehicle to prevent unauthorized devices from calculating the key seed in advance, thereby increasing the difficulty for unauthorized devices to calculate the Bluetooth pairing code using the key and key seed.

[0061] In step S12, Bluetooth pairing is initiated with the vehicle based on the second Bluetooth pairing code, so that a Bluetooth connection between the mobile terminal and the vehicle is established if the first Bluetooth pairing code matches the second Bluetooth pairing code.

[0062] In this embodiment of the disclosure, the mobile terminal can request the vehicle to broadcast the first Bluetooth pairing code when it calculates the second Bluetooth pairing code, or it can send the first Bluetooth pairing code to the vehicle when it calculates the second Bluetooth pairing code. Thus, both the vehicle and the mobile terminal can establish a Bluetooth connection between the mobile terminal and the vehicle if the first Bluetooth pairing code matches the second Bluetooth pairing code.

[0063] In step S13, if the Bluetooth connection is successful, Bluetooth car key information is sent to the vehicle via Bluetooth so that the vehicle can be controlled via a mobile terminal if the Bluetooth car key information is verified.

[0064] In this embodiment of the disclosure, when the Bluetooth car key information is verified, the vehicle can be unlocked, the doors can be opened and closed, and the vehicle can be started via a mobile terminal. For example, when the Bluetooth connection is successful, the mobile terminal and the vehicle verify each other by issuing certificates. After the verification is successful, a dynamic key is generated based on the certificate, and then the vehicle can be unlocked, the doors can be opened and closed, and the vehicle can be started via the mobile terminal.

[0065] In this embodiment of the disclosure, the mobile terminal may be a mobile terminal equipped with a Bluetooth module and having a vehicle Bluetooth application installed. The vehicle can then be unlocked via a vehicle unlock button displayed on the vehicle Bluetooth application, or the vehicle doors can be opened or closed via a door open / close button displayed on the vehicle Bluetooth application.

[0066] The above technical solution involves the vehicle broadcasting a key seed generated by the vehicle, and the vehicle calculating a first Bluetooth pairing code based on the key seed and the key sent by the mobile terminal. The mobile terminal, upon receiving the broadcast key seed, calculates a second Bluetooth pairing code based on the key seed and a pre-obtained key. It then initiates Bluetooth pairing with the vehicle based on the second Bluetooth pairing code. If the first and second Bluetooth pairing codes match, a Bluetooth connection is established between the mobile terminal and the vehicle. This prevents mobile terminals without the key from resolving the second Bluetooth pairing code and thus from establishing a Bluetooth connection with the vehicle. This prevents unauthorized external devices from connecting via Bluetooth and occupying the vehicle's Bluetooth communication channel for extended periods, avoiding situations where a mobile terminal carrying a Bluetooth digital car key cannot complete the Bluetooth pairing connection with the vehicle, leading to failure to unlock the vehicle using Bluetooth car key information. When the Bluetooth connection is successful, the mobile terminal sends Bluetooth car key information to the vehicle via Bluetooth, allowing control of the vehicle via the mobile terminal if the Bluetooth car key information is verified. This improves the stability of mobile terminal and vehicle control via Bluetooth car key information, optimizes the overall security of Bluetooth car key information, and enhances the user experience of using Bluetooth car key information.

[0067] In one embodiment of this disclosure, before calculating the second Bluetooth pairing code corresponding to the mobile terminal based on the key seed and a pre-received key in response to receiving a key seed broadcast by a vehicle, the process includes:

[0068] Determine the key seed for the first received vehicle broadcast;

[0069] It is understandable that "first time" refers to the first time any mobile terminal establishes a Bluetooth communication connection with the vehicle. After establishing the first Bluetooth communication connection with the vehicle, the mobile terminal can save the second Bluetooth pairing code. Similarly, after establishing the first Bluetooth communication connection with any mobile terminal, the vehicle can save the first Bluetooth pairing code.

[0070] The vehicle control method also includes:

[0071] If it is determined that the key seed is not the first time the vehicle broadcast has been received, the target second Bluetooth pairing code is determined from the historically generated second Bluetooth pairing codes based on the vehicle information carried in the key seed.

[0072] Bluetooth pairing is initiated with the vehicle based on the target second Bluetooth pairing code, so that a Bluetooth connection is established between the mobile terminal and the vehicle if the first Bluetooth pairing code matches the target second Bluetooth pairing code. Similarly, if the Bluetooth connection between the vehicle and the mobile terminal is successfully established using the target second Bluetooth pairing code, the mobile terminal also sends Bluetooth car key information to the vehicle via Bluetooth, so that the vehicle can be controlled via the mobile terminal if the Bluetooth car key information is verified.

[0073] In this way, instead of targeting the same mobile terminal, both the vehicle and the mobile terminal calculate the Bluetooth pairing code each time.

[0074] In one embodiment of this disclosure, the vehicle control method includes:

[0075] When the mobile terminal is an authenticated vehicle owner's mobile terminal, a key and Bluetooth car key information are sent to the target mobile terminal so that the target mobile terminal can execute the steps of receiving the key seed broadcast by the vehicle and sending the Bluetooth car key information to the vehicle via Bluetooth when the Bluetooth connection is successful.

[0076] In this embodiment, the authenticated vehicle owner's mobile terminal can send Bluetooth car key information from the cloud server to the target mobile terminal via SMS or instant messaging. For example, the target mobile terminal can be a mobile terminal with a vehicle Bluetooth application installed. When the target mobile terminal carries the key and enters the vehicle's broadcast range, it can receive the key seed broadcast by the vehicle. It can then calculate a second Bluetooth pairing code based on the key seed and the key, and initiate Bluetooth pairing with the vehicle based on the second Bluetooth pairing code. If the first Bluetooth pairing code matches the second Bluetooth pairing code, a Bluetooth connection is established between the mobile terminal and the vehicle. In this way, not only can the vehicle owner's mobile terminal securely control the vehicle using the Bluetooth car key information, but other mobile terminals, such as those carried by the vehicle owner's friends, can also securely control the vehicle using the Bluetooth car key information.

[0077] In one embodiment of this disclosure, the vehicle control method includes:

[0078] When the mobile terminal is an authenticated vehicle owner's mobile terminal, it requests the vehicle's Bluetooth car key information from the cloud server.

[0079] The Bluetooth car key information is calculated by the cloud server using symmetric or asymmetric encryption algorithms based on vehicle information. The cloud server can calculate both the Bluetooth car key information sent to the mobile terminal and the Bluetooth car key information sent to the vehicle. This allows the vehicle to authenticate the Bluetooth car key information based on both the information sent by the cloud server and the information sent by the mobile terminal when it receives the Bluetooth car key information from the mobile terminal.

[0080] Upon receiving Bluetooth car key information, a key is obtained randomly.

[0081] In this embodiment of the disclosure, the key can be obtained by random algorithms such as numerical random algorithms, Sherwood algorithms, Las Vegas algorithms and Monte Carlo algorithms, so that the vehicle owner's mobile terminal can execute the aforementioned steps S11 to S13.

[0082] Optionally, the vehicle control method includes:

[0083] When the mobile terminal is an authenticated vehicle owner's mobile terminal, it requests the vehicle's Bluetooth car key information from the cloud server.

[0084] Upon receiving Bluetooth car key information, a request is made to the cloud server to send a key. The key is obtained by the cloud server based on the hash of the vehicle information corresponding to the Bluetooth car key information.

[0085] In this embodiment, the method by which the cloud server obtains the key based on the vehicle information hash corresponding to the Bluetooth car key information is not limited.

[0086] In one implementation, if the vehicle owner's mobile terminal requests the cloud server to hash and obtain the Bluetooth car key information, the cloud server can send the Bluetooth car key information and the key together to the vehicle.

[0087] Figure 2 This is a flowchart illustrating a vehicle control method according to an exemplary embodiment, the vehicle control method being applied to a vehicle, such as... Figure 2 As shown, it includes the following steps.

[0088] In step S21, the key seed generated by the vehicle is broadcast, and the first Bluetooth pairing code on the vehicle is calculated based on the key seed and the key sent by the mobile terminal.

[0089] In one implementation, the vehicle can generate a key seed in a normal parked and powered-on state, and then broadcast the key seed. The vehicle can detect whether a mobile terminal exists within a preset range. If a mobile terminal exists within the preset range, the vehicle broadcasts the key seed generated by the vehicle.

[0090] In this embodiment of the present disclosure, the vehicle can calculate the first Bluetooth pairing code on the vehicle side based on the key seed and the key sent by the mobile terminal each time a new key seed is generated. The vehicle can also calculate the first Bluetooth pairing code on the vehicle side based on the key seed and the key sent by the mobile terminal each time a mobile terminal is detected within a preset range, thereby avoiding the calculation of invalid key seeds and the waste of computing resources.

[0091] In step S22, in response to receiving the second Bluetooth pairing code sent by the mobile terminal, the first Bluetooth pairing code is matched with the second Bluetooth pairing code. The second Bluetooth pairing code is calculated by the mobile terminal in response to receiving the key seed broadcast by the vehicle, based on the key seed and the key.

[0092] In this embodiment of the present disclosure, when the vehicle receives the second Bluetooth pairing code sent by the mobile terminal, it can calculate the first Bluetooth pairing code on the vehicle side according to the key seed and the key sent by the mobile terminal, and then match the first Bluetooth pairing code with the second Bluetooth pairing code.

[0093] Similarly, the vehicle can also calculate the first Bluetooth pairing code based on a preset, symmetric key generation algorithm. Since the first Bluetooth pairing code is calculated on the vehicle side and the second Bluetooth pairing code is calculated on the mobile terminal, different car manufacturers can choose different algorithms to calculate the Bluetooth pairing code. Moreover, because Bluetooth car key information needs to be transmitted via Bluetooth, unauthorized devices will not be able to deduce the encryption algorithm chosen by the manufacturer by analyzing the characteristics of the encrypted information.

[0094] In step S23, if the first Bluetooth pairing code matches the second Bluetooth pairing code, a Bluetooth connection is established between the mobile terminal and the vehicle.

[0095] For example, if the first Bluetooth pairing code and the second Bluetooth pairing code are the same, it is determined that the first Bluetooth pairing code and the second Bluetooth pairing code match, and a Bluetooth connection between the mobile terminal and the vehicle is established.

[0096] In step S24, if the Bluetooth connection is successful, the vehicle key information sent by the mobile terminal is received via Bluetooth, so that the vehicle can be controlled via the mobile terminal if the Bluetooth car key information is verified.

[0097] Optionally, before broadcasting the key seed generated by the vehicle, the following steps are included:

[0098] The key seed is generated randomly according to a preset period.

[0099] In this embodiment, the key seed can be updated every preset period, such as 15 seconds or 30 seconds, and the key seed is also randomly generated. Therefore, this scheme cannot be obtained by unauthorized devices through a brute-force approach that iterates through the Bluetooth pairing codes one by one. This further improves the security of controlling the vehicle via Bluetooth car key information.

[0100] The vehicle control method provided in this disclosure is illustrated below by way of a complete embodiment. See also: Figure 3 As shown in the embodiment of this disclosure, after the car owner's mobile terminal obtains the Bluetooth car key information and key, it sends the Bluetooth car key information and key to a target mobile terminal, such as a friend's mobile terminal, so that the target mobile terminal can control the vehicle based on the Bluetooth car key information and key. It can be noted that the car owner's mobile terminal can also control the vehicle based on the Bluetooth car key information and key.

[0101] In this embodiment of the disclosure, during the vehicle owner pairing stage, the vehicle owner's mobile terminal can complete the creation of Bluetooth car key information based on vehicle information and user identity information, and then obtain the Bluetooth car key information from the cloud server. After obtaining the Bluetooth car key information, the vehicle owner's mobile terminal can obtain a key S according to a random algorithm and send the key S to the vehicle corresponding to the Bluetooth car key information.

[0102] Furthermore, during the key sharing phase, the vehicle owner's mobile terminal can share Bluetooth car key information with the target mobile terminal. In this embodiment, the key S is sent to the target mobile terminal after the Bluetooth car key information is shared. Of course, the vehicle owner's mobile terminal can package the Bluetooth car key information and the key S together and share them with the target mobile terminal.

[0103] Furthermore, during the key-sharing phase, the vehicle can randomly generate a key seed at a preset period, calculate a first Bluetooth pairing code based on the key S and the key seed, and broadcast the key seed. Upon receiving the key seed, the target mobile terminal calculates a second Bluetooth pairing code based on the key S and the key seed. The target mobile terminal then initiates Bluetooth pairing with the vehicle based on the second Bluetooth pairing code. Upon receiving the second Bluetooth pairing code, the vehicle matches the first Bluetooth pairing code with the second Bluetooth pairing code. Therefore, when the first Bluetooth pairing code matches the second Bluetooth pairing code, the target mobile terminal can control the vehicle.

[0104] The above technical solution increases security because the key S is sent by the owner's mobile terminal to both the vehicle and the target mobile terminal during the owner pairing and key sharing phases, respectively. Therefore, during the key sharing phase, key S cannot be obtained by unauthorized devices. Furthermore, calculating Bluetooth pairing codes separately for the target mobile terminal and the vehicle reduces the possibility of unauthorized devices preempting available Bluetooth communication channel resources, improving the reliability and success rate of the Bluetooth connection between the mobile terminal and the vehicle. This, in turn, increases the success rate of using Bluetooth car key information and optimizes the overall security and user experience of Bluetooth car key information.
