[0012] It is understood that before using any of the technical solutions disclosed in each embodiment of the present disclosure, the type, scope of use, usage scenario, etc. of the personal information related to the present disclosure should be informed to the user in an appropriate manner in accordance with relevant laws and regulations, and the user's permission should be obtained.

[0013] [Example 1] FIG. 1 is a flowchart of an upgrade method in a first embodiment of the present application, which is applicable to upgrading a digital key system. The method can be performed by an upgrade device in the first embodiment of the present application, which can be implemented in software and / or hardware. As shown in FIG. 1, the method is performed by a target terminal connected to a CAN hardware device and a digital key system, respectively. Specifically, the method includes the following steps:

[0014] In S110, the identification information of the CAN hardware device and the target upgrade mode are obtained.

[0015] The target terminal may be an operating terminal connected to the CAN hardware device and the digital key system, for example, a computer. The digital key system may be divided into a master module and a module to be upgraded, and there may be multiple modules to be upgraded. The master module includes a pre-processing node and a master controller node, and the module to be upgraded includes a slave controller node. The target terminal is connected to the CAN hardware device and the digital key system, respectively, and upgrades the digital key system based on the CAN hardware device. The master module in the digital key system and the target terminal communicate via a CAN channel. The target terminal can receive an upgrade file in the digital key system to upgrade the master module and / or the module to be upgraded. The module to be upgraded in the digital key system can be regarded as the flash partition of the master module and can perform the upgrade operation. The CAN hardware device and the master module in the digital key system can communicate using the CAN UDS protocol.

[0016] The CAN hardware device can be a CAN OE or a Zhou Ligong CAN box. The identification information of the CAN hardware device can be used to determine the CAN hardware device required for the digital key system upgrade. Organizations or teams that do not have the means to purchase CAN OE hardware can upgrade their digital key system with a Zhou Ligong CAN box to reduce upgrade costs.

[0017] Here, the target upgrade mode can be divided into two modes: the first upgrade mode can upgrade both the master module and the upgrade target module, and the second upgrade mode can upgrade only the upgrade target module. For example, the first upgrade mode can be a stage upgrade mode, and the second upgrade mode can be a single-antenna upgrade mode.

[0018] Specifically, the method for obtaining the identification information of the CAN hardware device and the target upgrade mode may be such that the target terminal polls and searches for the CAN hardware device currently connected to the target terminal, obtains the identification information of the CAN hardware device, and determines the target upgrade mode.

[0019] Preferably, obtaining the identification information and the target upgrade mode of the CAN hardware device comprises: displaying a list of CAN hardware devices in response to detecting a user touching a load device control in the upgrade interface; In response to detecting a user's touch operation on a CAN hardware device in the CAN hardware device list, acquiring identification information of the CAN hardware device; In response to detecting a user touching a target upgrade mode control in the upgrade interface, obtaining the target upgrade mode.

[0020] Here, the upgrade interface may include contents such as load device control, upgrade mode, master module, upgrade target module, pre-processing node, master controller node, slave controller node, version inquiry, and upgrade progress display frame, etc. The CAN hardware device list may include identification information corresponding to at least one CAN hardware device.

[0021] Specifically, the method of displaying the CAN hardware device list in response to detecting a user's touch operation on a load device control in the upgrade interface may be a method of polling and searching for CAN hardware devices connected to the target terminal in response to detecting a user's tap on a load device control in the upgrade interface, and displaying the CAN hardware device list.

[0022] Specifically, a method for acquiring identification information of a CAN hardware device in response to detection of a user's touch operation on a CAN hardware device in a CAN hardware device list may be a method for selecting the required CAN hardware from the displayed CAN hardware device list, and acquiring identification information of the CAN hardware device corresponding to the selected CAN hardware in response to detection that the user has tapped to select the required CAN hardware device.

[0023] Specifically, the method of obtaining the target upgrade mode in response to detecting a user touch operation on a target upgrade mode control in the upgrade interface may be a method in which the user taps the target upgrade mode control in the upgrade interface to confirm the target upgrade mode.

[0024] In S120, a target upgrade node is determined based on the target upgrade mode.

[0025] Here, the target upgrade node is a node that needs to be upgraded in the master module and / or the upgrade target module in the digital key system selected according to actual needs, where the master module includes a pre-processing node and a master controller node, and the upgrade target module includes a slave controller node.

[0026] Specifically, the method for determining the target upgrade node based on the target upgrade mode may be as follows: after determining the target upgrade mode, select a master module that needs to be upgraded and / or a module to be upgraded; the master module that needs to be upgraded selects a pre-processing node and a master controller node that needs to be upgraded; the module to be upgraded selects a slave controller node that needs to be upgraded; and the pre-processing node, the master controller node that needs to be upgraded, and the slave controller node that needs to be upgraded are all regarded as the target upgrade node. The method for determining the target upgrade node based on the target upgrade mode may further be as follows: determine a corresponding set of nodes to be upgraded based on the target upgrade mode, update the set of nodes to be upgraded based on the nodes to be upgraded selected by the user, and determine the target upgrade node based on the updated set of nodes to be upgraded.

[0027] Preferably, determining the target upgrade node based on the target upgrade mode includes: If the target upgrade mode is a first upgrade mode, generate a first set of upgrade target nodes according to the pre-processing node, the master controller node and the slave controller node, and determine a target upgrade node according to the first set of upgrade target nodes; If the target upgrade mode is a second upgrade mode, generating a second set of nodes to be upgraded based on the slave controller node, and determining the target upgrade node based on the second set of nodes to be upgraded.

[0028] Here, the master controller node may include a BOOT upgrade node, an APP upgrade node, and a BLE upgrade node, and the slave controller node may include a BOOT upgrade node, an MCU upgrade node, and a BLE upgrade node, where the APP upgrade node may represent the application software of the master module MCU, and the BLE upgrade node may represent BLE and BLE&UWB. When selecting and upgrading the BOOT upgrade node among the slave controller nodes, the MCU upgrade node among the master controller node and the slave controller node, and the BLE upgrade node among the slave controller nodes, cannot be upgraded. When upgrading the MCU upgrade node among the master controller node and the slave controller node, and the BLE upgrade node among the slave controller nodes, the BOOT upgrade node among the slave controller nodes cannot be upgraded. Note that only when upgrading the master module in the digital key system, a pre-processing node needs to be selected. That is, in the first upgrade mode, when a user selects the first upgrade node of the master controller of the master module, a pre-processing node needs to be selected and a CAN upgrade protocol service suitable for different vehicle manufacturers needs to be selected based on the pre-processing node to pre-process the digital key system.

[0029] Here, the first set of upgrade target nodes is all nodes when the target upgrade mode is the first upgrade mode, i.e., the pre-processing node, the master controller node and all slave controller nodes, and the second set of upgrade target nodes is all slave controller nodes when the target upgrade mode is the second upgrade mode.

[0030] Specifically, when the target upgrade mode is a first upgrade mode, a first set of upgrade target nodes is generated based on the pre-processing node, the master controller node and the slave controller node, and the target upgrade node is determined based on the first set of upgrade target nodes; in response to detecting a user's touch operation on the first upgrade mode control, a first set of upgrade target nodes is generated based on the pre-processing node, the master controller node and the slave controller node, and the upgrade target nodes that need to be upgraded according to actual needs are selected, and the target upgrade node is determined based on the first set of upgrade target nodes and the upgrade target nodes that need to be upgraded.

[0031] Specifically, when the target upgrade mode is the second upgrade mode, the method of generating a second set of upgrade target nodes based on slave controller nodes and determining the target upgrade nodes based on the second set of upgrade target nodes may be: in response to detecting a user's touch operation on the second upgrade mode control, generating a second set of upgrade target nodes based on all slave controller nodes, selecting upgrade target nodes that need to be upgraded according to actual needs, and determining the target upgrade nodes based on the second set of upgrade target nodes and the upgrade target nodes that need to be upgraded.

[0032] Preferably, determining the target upgrade node based on the first set of upgrade target nodes includes: In response to detecting a touch operation by a user on a first upgrade target node among the master controller nodes, remove a second upgrade target node among the slave controller nodes from a first upgrade target node set, and determine a target upgrade node based on the first upgrade target node; In response to detecting a user's touch operation on a third upgrade target node among the slave controller nodes, removing a second upgrade target node among the slave controller nodes from the first upgrade target node set, and determining a target upgrade node based on the third upgrade target node; In response to detecting a user's touch operation on a second upgrade target node among the slave controller nodes, clearing the first upgrade target node set and determining a target upgrade node based on the second upgrade target node.

[0033] Here, the first upgrade target node may be at least one of the BOOT upgrade node, the APP upgrade node, and the BLE upgrade node in the master controller, the second upgrade target node may be the BOOT upgrade node in the slave controller, and the third upgrade target node may be at least one of the MCU upgrade node and the BLE upgrade node in the slave controller.

[0034] Specifically, the method of removing a second upgrade target node among the slave controller nodes from a first upgrade target node set in response to detecting a user's touch operation on a first upgrade target node among the master controller nodes and determining a target upgrade node based on the first upgrade target node may be, when the target upgrade mode is the first upgrade mode, removing all second upgrade target nodes among the slave controller nodes from the first upgrade target node set upon detecting that the user has selected and upgraded the first upgrade target node among the master controller nodes. The method of determining a target upgrade node based on the first upgrade target node may further be, based on the first upgrade target node selected by the user and a third upgrade target node selected by the user among the slave controller nodes in the upgrade target module selected by the user. The method of determining a target upgrade node based on the first upgrade target node may further be, based on the first upgrade target node selected by the user and a third upgrade target node selected by the user among the slave controller nodes in the upgrade target module selected by the user.For example, when the target upgrade mode is a stage upgrade mode, if the user selects to upgrade the BOOT upgrade node and the APP upgrade node in the master controller, the BOOT upgrade node in the slave controller is deleted from the first set of nodes to be upgraded, that is, the BOOT upgrade node in the slave controller cannot be selected for upgrade, and the pre-processing node, the BOOT upgrade node and the APP upgrade node in the master controller are determined as the target upgrade nodes.

[0035] Specifically, the method of removing the second upgrade target node among the slave controller nodes from the first set of upgrade target nodes in response to detecting a user's touch operation on a third upgrade target node among the slave controller nodes and determining the target upgrade node based on the third upgrade target node may be: if the target upgrade mode is the first upgrade mode, when it is detected that the user has selected a third upgrade target node among the slave controller nodes to be upgraded, the second upgrade target node among all slave controller nodes is removed from the first set of upgrade target nodes and the target upgrade node is determined based on the third upgrade target node selected by the user. The method of determining the target upgrade node based on the third upgrade target node may further be: determining the target upgrade node based on the third upgrade target node selected by the user and the first upgrade target node selected by the user. For example, if the target upgrade mode is the stage upgrade mode, when the user selects an MCU upgrade node in the slave controller to be upgraded, the BOOT upgrade node in the slave controller is removed from the first set of upgrade target nodes, i.e., the BOOT upgrade node in the slave controller cannot be selected for upgrade, and the pre-processing node, the MCU upgrade node in the slave controller, may be determined as the target upgrade node.

[0036] Specifically, the manner of clearing the first set of upgraded nodes and determining the target upgrade node based on the second upgraded node in response to detecting a user's touch operation on a second upgraded node among the slave controller nodes may be as follows: if the target upgrade mode is the first upgrade mode, when it is detected that the user selects a second upgraded node among the slave controller nodes to be upgraded, the first set of upgraded nodes may be directly cleared and the second upgraded node among the slave controller nodes may be determined as the target upgrade node. For example, if the target upgrade mode is the stage upgrade mode, when the user selects a BOOT upgrade node in the slave controller to be upgraded, the BOOT upgrade node in the slave controller may be the target upgrade node.

[0037] Preferably, determining the target upgrade node based on the first set of upgrade target nodes includes: Obtaining a target upgrade target module; determining a target upgrade node based on the target upgrade target module and the first set of upgrade target nodes.

[0038] Here, the target upgrade module may be a default upgrade module or a target upgrade module selected by a user according to actual needs. For example, there may be multiple upgrade modules, and the target upgrade module may be determined based on the identification information corresponding to the upgrade module, and the identification information corresponding to the upgrade module may be the number of the upgrade module.

[0039] Specifically, the method for acquiring the target upgrade target module may be to display a list of upgrade target modules in response to detection of a user's touch operation on an upgrade target module control in an upgrade interface, and to acquire the target upgrade target module in response to detection of a user's touch operation on identification information corresponding to the target upgrade target module in the upgrade target module list.

[0040] Specifically, the method for determining the target upgrade node based on the target upgrade target module and the first set of upgrade target nodes may be as follows: determine the target upgrade target module; determine the upgrade target node corresponding to the target upgrade target module based on the target upgrade target module; if a second upgrade target node in the slave controller of the target upgrade target module is selected, clear the first set of upgrade target nodes and determine the second upgrade target node in the slave controller of the target upgrade target module as the target upgrade node; if a third upgrade target node in the slave controller of the target upgrade target module is selected, delete the second upgrade target node in the slave controller of the target upgrade target module from the first set of upgrade target nodes; and determine the first upgrade target node, pre-processing node and third upgrade target node in the master controller of the master module selected by the user as the target upgrade nodes.For example, if the target upgrade mode is stage upgrade mode, the selected target upgrade module is the third upgrade module, and the BOOT upgrade node of the third upgrade module is selected, the BOOT upgrade node of the third upgrade module is the target upgrade node; if the target upgrade mode is stage upgrade mode, the selected target upgrade module is the third upgrade module, and the BOOT upgrade node and APP upgrade node of the master controller are selected, and the MCU upgrade node and BLE upgrade node of the slave controller of the third upgrade module are selected, the pre-processing node, the BOOT upgrade node and APP upgrade node of the master controller, the MCU upgrade node of the third upgrade module, and the BLE upgrade node of the third upgrade module may be the target upgrade node.

[0041] Preferably, determining the target upgrade node based on the second set of upgraded nodes includes: In response to detecting a user's touch operation on a second upgrade target node among the slave controller nodes, clearing the second upgrade target node set and determining a target upgrade node based on the second upgrade target node; In response to detecting a user's touch operation on a third upgrade target node among the slave controller nodes, deleting the second upgrade target node among the slave controller nodes from the second upgrade target node set, and determining a target upgrade node based on the third upgrade target node.

[0042] Specifically, the manner of clearing the second set of upgrade target nodes and determining the target upgrade node based on the second upgrade target node in response to detecting a user's touch operation on a second upgrade target node among the slave controller nodes may be: if the target upgrade mode is the second upgrade mode, upon detecting that the user selects a second upgrade target node among the slave controller nodes to be upgraded, the second set of upgrade target nodes may be cleared and the second upgrade target node among the slave controller nodes selected by the user may be directly determined as the target upgrade node. For example, if the target upgrade mode is a single-antenna upgrade mode and the user selects a BOOT upgrade node in the slave controller to be upgraded, the second set of upgrade target nodes may be cleared and the BOOT upgrade node in the slave controller selected by the user may be determined as the target upgrade node.

[0043] Specifically, the manner of removing the second upgrade target node among the slave controller nodes from the second set of upgrade target nodes in response to detecting a user's touch operation on a third upgrade target node among the slave controller nodes and determining the target upgrade node based on the third upgrade target node may be as follows: when the target upgrade mode is the second upgrade mode, if it is detected that a user selects a third upgrade target node among the slave controller nodes to be upgraded, the second upgrade target node among the slave controller nodes is removed from the second set of upgrade target nodes, and the third upgrade target node among the slave controller nodes selected by the user is determined as the target upgrade node. For example, when the target upgrade mode is a single-antenna upgrade mode and a user selects an MCU upgrade node in the slave controller to be upgraded, the BOOT upgrade node in the slave controller may be removed from the second set of upgrade target nodes, and the MCU upgrade node in the slave controller selected by the user is determined as the target upgrade node.

[0044] In addition, in the second upgrade mode, if the target upgrade module is not selected and the second or third upgrade target node of the slave controller is directly selected, the second or third upgrade target node of the slave controller will be upgraded in the default upgrade module, and if the target upgrade module is confirmed, the second or third upgrade target node of the slave controller will be upgraded in the target upgrade module.

[0045] In S130, the digital key system is upgraded based on the upgrade file corresponding to the target upgrade node and the identification information of the CAN hardware device.

[0046] Specifically, the method for upgrading the digital key system based on the upgrade file corresponding to the target upgrade node and the identification information of the CAN hardware device may be to determine the identification information of the CAN hardware device, and then load the upgrade file corresponding to the target upgrade node based on the target upgrade node to upgrade the digital key system. Furthermore, when the upgrade file is loaded, it needs to be checked, including determining whether the upgrade file is complete, whether it has been tampered with, and whether a loading error occurs. If the check is successful, the digital key system is upgraded; if the check is unsuccessful, the digital key system upgrade is stopped, and the upgrade interface can display the upgrade file check process and the digital key system upgrade progress.

[0047] The technical solution of this embodiment obtains the identification information and target upgrade mode of the CAN hardware device, determines the target upgrade node based on the target upgrade mode, and upgrades the digital key system based on the upgrade file corresponding to the target upgrade node and the identification information of the CAN hardware device. This solves the problems that the operation interface of the CAN upgrade project is complicated, additional software needs to be installed and configured, resulting in low upgrade efficiency, and the CAN upgrade project includes source code and cannot be provided to organizations and teams other than customers or research and development for use. It does not require the installation of additional software, is easy to operate, further improves upgrade efficiency, does not require upgrading based on source code, and further protects the source code from disclosure.

As shown in FIG. 2, the upgrade device specifically includes an acquisition module 210, a determination module 220, and an upgrade module 230.

[0049] Wherein, the acquisition module 210 is used to acquire the identification information and target upgrade mode of the CAN hardware device; The determining module 220 is used for determining a target upgrade node according to the target upgrade mode; The upgrade module 230 is used to upgrade the digital key system according to the upgrade file corresponding to the target upgrade node and the identification information of the CAN hardware device.
