The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0018] Embodiment 1 Please refer to Figure 1 , which shows the UWB digital key management method in the first embodiment of the present invention. The method includes steps S10 to S11.

[0019] Step S10, when a key deletion request sent by a user through a preset port is received, the key deletion request is sent to the vehicle-mounted Bluetooth module and the cloud server respectively.

[0020] Among them, after the UWB digital key is shared with others for use, the device information of others will be stored all the time, and others can enter the vehicle again through the shared key. To manage the key information of the UWB digital key, this user key management method for the mobile phone UWB digital key is designed, enabling users to manage key information. UWB is ultra-wideband Bluetooth.

[0021] Specifically, users can manage keys through a preset port. For example, the UWB digital key management on the in-vehicle device side and the UWB digital key management on the mobile device side (mobile phone), and a corresponding key deletion request is sent to the vehicle-mounted Bluetooth module and the cloud server storing the key information through the preset port.

[0022] More specifically, the cloud server may include one or more cloud servers: the cloud server of the vehicle manufacturer, the cloud server of the UWB digital key function development manufacturer, and the cloud server of the mobile phone APP. Among them, the key information in the cloud is only stored in the cloud server of the UWB digital key function development manufacturer, and other cloud servers only serve as the transmission channels for key information to the mobile phone or the vehicle, which can ensure the security of data stored in the cloud server.

[0023] Further, when the preset port is the in-vehicle device side, when it is detected that the user enters the UWB digital key management interface of the in-vehicle device, the in-vehicle device requests key information from the vehicle-mounted Bluetooth module; After receiving the key information request from the in-vehicle device, the vehicle-mounted Bluetooth module sends the current key situation to the in-vehicle device; The in-vehicle device sends a key deletion request to the vehicle-mounted Bluetooth module and the gateway; After receiving the key deletion request sent by the in-vehicle device, the gateway forwards it to the vehicle networking intelligent terminal; After the vehicle networking intelligent terminal receives the key deletion request forwarded by the gateway, it sends a key deletion instruction to the cloud server.

[0024] Exemplarily, when the user enters the IVI (in-vehicle infotainment) UWB digital key management interface, the IVI requests key information from the BLE (Bluetooth module); After the BLE accepts the key information request from the IVI, it sends the current key situation to the IVI; The IVI issues a key deletion request to the BLE and the GW (gateway). After receiving the key deletion instruction, the BLE executes a timeout judgment mechanism; After the GW receives the key deletion request sent by the IVI, it forwards it to the TBOX (vehicle networking intelligent terminal), that is, the vehicle's remote communication module; After the TBOX receives the key deletion request forwarded by the GW, it sends a key deletion instruction to the cloud.

[0025] Furthermore, when the preset port is a mobile terminal, the mobile terminal issues a key deletion request to the cloud; After the cloud server receives the key deletion request from the mobile terminal, it passes the received key deletion request to the vehicle networking intelligent terminal; After the vehicle networking intelligent terminal receives the key deletion request sent by the cloud, it passes the key deletion request to the gateway; After the gateway receives the key deletion request from the vehicle networking intelligent terminal, it passes the key deletion request to the in-vehicle Bluetooth module.

[0026] Exemplarily, the mobile phone APP and the mobile phone wallet issue a key deletion request to the cloud; After the cloud receives the key deletion requests from the mobile phone APP and the mobile phone wallet, it passes the received key deletion requests to the vehicle TBOX; After the TBOX receives the key deletion request sent by the cloud, it passes the key deletion request to the GW; After the GW receives the key deletion request from the TBOX, it passes the key deletion request to the BLE.

[0027] Step S11: Delete the key information stored in one of the in-vehicle Bluetooth module and the cloud server according to the key deletion request, and after the deletion is successful, send the deletion result to the other of the in-vehicle Bluetooth module and the cloud to synchronously delete the key information stored therein.

[0028] Among them, according to the key deletion requests sent from different ports, first delete the key information of one of them, send the deletion result to the other, delete the key information of the other, and synchronize the key deletion information.

[0029] Specifically, when the preset port is the in-vehicle unit, after the cloud server receives the key deletion request from the vehicle networking intelligent terminal, it deletes the key information stored in the cloud server; The cloud server sends the deletion result of the key information to the vehicle networking intelligent terminal, and the vehicle networking intelligent terminal sends the deletion result of the cloud server to the gateway; The gateway sends the deletion result of the cloud server to the in-vehicle Bluetooth module, and the in-vehicle Bluetooth module synchronously deletes the key information stored therein and feeds back the successful deletion of the key information to the in-vehicle unit.

[0030] Exemplarily, after the GW receives the key deletion request sent by the IVI, it forwards it to the TBOX (vehicle networking intelligent terminal); After the TBOX receives the key deletion request forwarded by the GW, it sends a key deletion instruction to the cloud. After the cloud receives the key deletion request from the TBOX, it deletes the key information stored in the cloud; After the key information stored in the cloud is deleted, it synchronizes the key information to the mobile phone APP; The cloud sends the key information deletion result to the TBOX; The TBOX sends the cloud key deletion result to the GW; The GW sends the cloud key deletion result to the BLE; synchronously deletes the key information stored in the BLE.

[0031] When the preset port is the mobile terminal, after the in-vehicle Bluetooth module receives the key deletion request sent by the gateway, it deletes the stored key information and feeds back the deletion result to the gateway; After the gateway receives the key information deletion result fed back by the in-vehicle Bluetooth module, it sends the key information deletion result of the in-vehicle Bluetooth module to the vehicle networking intelligent terminal; After the vehicle networking intelligent terminal receives the key information deletion result of the in-vehicle Bluetooth module sent by the gateway, it uploads the key information deletion result of the in-vehicle Bluetooth module to the cloud server; After the cloud server receives the key information deletion result of the in-vehicle Bluetooth module uploaded by the vehicle networking intelligent terminal, it synchronously deletes the key information stored in the cloud server and feeds back the successful key information deletion result to the mobile terminal, and the mobile terminal deletes the key information according to the result fed back by the cloud server.

[0032] Exemplarily, after the BLE receives the key deletion request sent by the GW, it deletes the stored key information and feeds back the deletion result to the GW; After the GW receives the key information deletion result fed back by the BLE, it sends the BLE key information deletion result to the TBOX; After the TBOX receives the BLE key information deletion result sent by the GW, it uploads the BLE key information deletion result to the cloud; After the cloud receives the BLE key information deletion result uploaded by the TBOX, it synchronously deletes the key information stored in the cloud, and feeds back the successful result of the key information deletion to the mobile wallet and the mobile APP. The mobile wallet and the APP delete the key information according to the result fed back by the cloud.

[0033] In summary, when the present invention receives a key deletion request sent by a user through a preset port, it sends the key deletion request to the in-vehicle Bluetooth module and the cloud server respectively; deletes the key information stored in one of the in-vehicle Bluetooth module and the cloud server according to the key deletion request, and after the deletion is successful, sends the deletion result to the other of the in-vehicle Bluetooth module and the cloud to synchronously delete the key information stored therein, and deletes the shared digital key. It solves the problem in the prior art that after the UWB digital key is shared with others for use, the device information of others will be stored all the time, and others can enter the vehicle again through the already shared key, resulting in low vehicle security.

[0034] Embodiment 2 This embodiment also proposes a method for managing UWB digital keys. The difference between the method for managing UWB digital keys in this embodiment and the method for managing UWB digital keys in Embodiment 1 is as follows: After the step of the vehicle head unit sending the key deletion request to the in-vehicle Bluetooth module and the gateway, the following steps are further included: The in-vehicle Bluetooth module executes a timeout judgment mechanism after receiving the key deletion request; If the in-vehicle Bluetooth module receives the deletion result sent by the gateway to the cloud server before triggering the timeout judgment mechanism, it synchronously deletes the key information stored in the in-vehicle Bluetooth module and feeds back the successful deletion of the key information to the vehicle head unit; If the in-vehicle Bluetooth module triggers the timeout judgment mechanism, it feeds back the failure of the key information deletion to the vehicle head unit and synchronously uploads the log data to the cloud server, and the cloud server synchronizes the log data of the in-vehicle Bluetooth module and synchronizes the key information.

[0035] After the step that the cloud server synchronously deletes the key information stored in the cloud server and feeds back the successful result of the key information deletion to the mobile terminal after receiving the key information deletion result of the in-vehicle Bluetooth module uploaded by the vehicle networking intelligent terminal, the following steps are further included: If the cloud server receives the timeout of the deletion key information result fed back by the vehicle networking intelligent terminal, it feeds back the failure of the key information deletion to the mobile terminal and synchronously sends down the log data to the in-vehicle Bluetooth module, and the in-vehicle Bluetooth module synchronizes the key information according to the log data sent down by the cloud server.

[0036] Among them, whether the key deletion request is initiated from the mobile phone side or the in-vehicle device side, a corresponding timeout mechanism is set, and after the timeout, the log data will be uploaded via Bluetooth or the log data will be sent from the cloud to ensure that the key information cannot be deleted when the network is poor or in other situations such as receiving a data security attack, avoiding the situation where the key information received on the in-vehicle device side and the mobile phone side is inconsistent.

[0037] In summary, for the UWB digital key management method in the above embodiments of the present invention, when receiving a key deletion request sent by a user through a preset port, the key deletion request is respectively sent to the in-vehicle Bluetooth module and the cloud server; according to the key deletion request, the key information stored in one of the in-vehicle Bluetooth module and the cloud server is deleted, and after the deletion is successful, the deletion result is sent to the other of the in-vehicle Bluetooth module and the cloud to synchronously delete the key information stored therein, and the shared digital key is deleted.
