It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described herein.

[0028] Example 1

[0029] Figure 1This is a flowchart of a hot update method for vehicle configuration information according to Embodiment 1 of this application. This embodiment is applicable to situations where a small number of configuration parameters in the configuration file of a vehicle-side remote upgrade system need to be updated. This can be executed by a vehicle-side remote upgrade system device, which can be implemented in hardware and / or software. This vehicle-side remote upgrade system device can be configured in a computer device, such as a vehicle terminal device. Figure 1 As shown, the method includes:

[0030] S110. When the target vehicle's on-board remote upgrade system meets the preset update status conditions, a system configuration file verification request is sent to the remote upgrade cloud.

[0031] The system configuration file verification request instructs the remote upgrade cloud to perform file consistency verification and file version number consistency verification between the vehicle-side system configuration file and the cloud-based system configuration file. It should be noted that file consistency verification can refer to verifying the file digest value of each sub-configuration file within the configuration file, while file version number consistency verification can refer to verifying the version number of each sub-configuration file within the configuration file. The file version number of the configuration file can be used to identify the updated version of the vehicle's infotainment system. Optionally, the vehicle-side remote upgrade system can refer to a distributed software management system installed in the vehicle. It is responsible for receiving cloud-based system upgrade tasks, managing the system upgrade process, and ensuring system upgrade security; it is the core carrier for realizing remote upgrades of the vehicle's infotainment system. Optionally, the vehicle-side system configuration file and the cloud-based system configuration file can be considered the same system configuration file, differing only in their deployment location: one is deployed on the vehicle's infotainment terminal, and the other is deployed in the cloud.

[0032] In this embodiment of the invention, the preset update status conditions may include active update conditions or passive update conditions. For example, active update conditions may include the user actively initiating a configuration data update request through the vehicle system, and passive update conditions may include remotely upgrading the cloud to push configuration data to the target vehicle.

[0033] Optionally, in this embodiment of the invention, the cloud system configuration file can independently manage the configuration information of the vehicle-side remote upgrade system. The file version number of the cloud system configuration file is decoupled from the calibration information of the vehicle's electronic control unit and the vehicle's logistics configuration information. It can generate configuration data for different scenarios based on vehicle model, vehicle configuration, and after-sales parts replacement, and distribute this data to the vehicle terminal, achieving precise configuration management tailored to each vehicle. Optionally, the configuration data stored in the cloud system configuration file can be used to manage the upgrade process of the vehicle-side remote upgrade system, control the behavior of the vehicle's electronic system, and define key parameter sets for function switches. For example, this may include upgrade strategy configurations: batch push ratio, upgrade time window, and network environment requirements; vehicle function switches: driver assistance function on / off, vehicle UI display mode, and multimedia function restrictions; system parameter definitions: ECU (Electronic Control Unit) operating thresholds, sensor calibration values, and communication protocol versions; and device authentication information: cloud server address, identity authentication key, and encryption algorithm parameters.

[0034] Optionally, in one specific implementation, the cloud system configuration file, the OTA (Over-the-Air Technology) system, and the controller software maintain independent boundaries of responsibility, interacting through standardized interfaces and protocols to avoid mutual penetration of their internal logic. For example, the cloud system configuration file and the controller software can be decoupled as follows: An independent configuration data specification is defined in the cloud system configuration file. For both the cloud system configuration file and the controller software, the format, encoding, and storage location of the configuration data in the configuration file are separated from the controller software. Standard data configuration guidelines are established in the controller software, allowing it to read configuration data from the configuration file according to these guidelines without participating in the definition of the configuration data. Backward compatibility of the configuration data is implemented in the controller software, meaning that new version configuration data can be recognized by older versions of the controller software, and older version configuration data can be compatible with newer versions of the controller software, avoiding version iteration issues. Incompatibility issues can be addressed, for example, by setting default values ​​when adding new configuration fields: For instance, adding an `auto_shutoff_time` field (automatic shutdown time) for seat heating, while defining a default value of 30 minutes in the controller software if this field is not read. Compatibility handling is also implemented for obsolete configuration fields: when a configuration field is no longer used, the controller software automatically ignores it when reading it, without affecting normal operation. For example, the `old_temp_unit` field in the old version is skipped by the new version software. It should be noted that "new version" and "old version" in this embodiment can refer to the order of time; for example, the timestamp information of the new version configuration data is later than the timestamp information of the old version controller software. The functional logic implementation of the controller software is decoupled from the configuration data, so that the functional logic implementation of the controller software does not depend on specific configuration data. The configuration data is only used as parameter input, and updates to the configuration data do not affect the functional logic implementation of the controller software. For example, the functional logic implementation adopts a parameterized design: for the kinetic energy recovery function, the functional logic implementation of the controller software is to "adjust the motor torque according to the recovery intensity parameter," while the specific value of the recovery intensity (levels 1-5) is defined by the configuration data. Adjusting the level value in the configuration data does not require modifying the functional logic code.

[0035] The cloud system configuration file and the OTA system can be decoupled in the following ways: Establish a standardized configuration data transmission protocol between the cloud system configuration file and the OTA system. This ensures that the transmission of configuration data follows common network protocols and formats, eliminating reliance on the OTA system's proprietary customized logic. The OTA system only needs to transmit data and does not need to parse specific configuration data. For example, it can use common hash algorithms such as MD5 and SHA256 to verify the integrity of the configuration file. The OTA system only needs to calculate and compare hash values ​​and does not need to understand the specific meaning of the configuration data. Separate the data transmission business and upgrade management business of the OTA system. For example, divide the OTA system into a lower-level transport layer responsible for data transmission and a lower-level upgrade management layer. The upper-level business layer, responsible for upgrade management, is only responsible for controlling the upgrade process, such as creating upgrade tasks, monitoring progress, and providing feedback. It does not participate in the parsing and processing of specific configuration data; configuration data upgrades rely solely on the underlying transport layer. An independent triggering mechanism for configuration data upgrades is deployed, allowing configuration data upgrades to be triggered independently of other upgrade tasks in the OTA system. This eliminates the need to rely on OTA system version updates to support new configuration upgrade requirements. For example, request and response interfaces for configuration upgrades are defined on both the vehicle and cloud sides. After the cloud sends a configuration data upgrade request, the vehicle directly triggers the update of the configuration file upon receiving the request, eliminating the need for a full OTA system upgrade.

[0036] It's important to clarify that the cloud-based system configuration file can refer to a set of parameters stored in the ECU, such as instructional data like function switch thresholds, control logic parameters, and permission configuration codes. This serves as an "operation manual" for the controller software, instructing the controller's control logic, such as the heating power corresponding to the seat heating temperature level and the motor torque parameters corresponding to the kinetic energy recovery intensity level. The OTA system refers to the technical framework and management process for remote upgrades, including a cloud server, vehicle-side communication module, upgrade verification mechanism, and installation execution logic. It acts as a "transmission channel + installation manager" for configuration data, system software, and controller software, ensuring the secure and reliable delivery and deployment of necessary updates. The controller software refers to the executable code running on the ECU, used to implement vehicle control actions, such as adjusting charging and discharging strategies based on the battery management system's configuration parameters. By decoupling the configuration data and version in the cloud-based system configuration file, the cloud can directly update the configuration data without requiring remote upgrades to the vehicle-side system or controller software version, reducing version iteration dependencies during configuration updates and improving efficiency.

[0037] S120. Based on the verification result of the system configuration file verification request, send a request to the remote upgrade cloud to obtain the cloud system configuration file and obtain the cloud system configuration file.

[0038] Optionally, based on the verification result of the system configuration file verification request, a request to obtain the cloud system configuration file is sent to the remote upgrade cloud. Obtaining the cloud system configuration file includes: if the vehicle-side remote upgrade system receives a verification result from the remote upgrade cloud indicating a system configuration file inconsistency, it will send a request to obtain the cloud system configuration file to the remote upgrade cloud; after receiving the cloud system configuration file from the remote upgrade cloud, it will store the cloud system configuration file in the spare partition of the vehicle-side remote upgrade system. It should be noted that the setting of the spare partition can prevent the normal operation of the current vehicle-side remote upgrade system. Optionally, the spare partition can be configured adaptively according to those skilled in the art.

[0039] Specifically, if the vehicle-side remote upgrade system receives a verification result from the remote upgrade cloud indicating that the system configuration file is consistent, it means that the latest configuration data stored in the remote upgrade cloud is consistent with the configuration data stored in the vehicle-side remote upgrade system, and there is no need to update the configuration data of the vehicle-side system configuration file. If the vehicle-side remote upgrade system receives a verification result from the remote upgrade cloud indicating that the system configuration file is inconsistent, it means that the latest configuration data stored in the remote upgrade cloud is inconsistent with the configuration data stored in the vehicle-side remote upgrade system. In this case, the vehicle terminal needs to send a configuration data update request to the remote upgrade cloud and update the configuration data of the vehicle-side system configuration file according to the latest configuration data stored in the cloud.

[0040] Optionally, in this embodiment of the invention, the vehicle-side remote upgrade system and the remote upgrade cloud can communicate using the HTTP protocol (HyperText Transfer Protocol).

[0041] S130. Perform consistency verification on the vehicle-side system configuration file and the cloud-side system configuration file, and generate a configuration file update task based on the consistency verification result.

[0042] S140. Based on the current task execution status of the target system update task, perform a hot update of the vehicle-side system configuration file according to the configuration file update task.

[0043] Among them, the target system update task can refer to the task of performing a system update on the vehicle's infotainment system by executing the vehicle-side remote upgrade system.

[0044] It should be noted that before modifying the vehicle-side system configuration file, you need to ensure that there are no system upgrade tasks currently running on the vehicle-side remote upgrade system.

[0045] This application embodiment compares whether the vehicle-side system configuration file and the cloud-side system configuration file are consistent. In the case of inconsistency, priority control is used to perform hot updates on the configuration data in the vehicle-side system configuration file based on the configuration data in the cloud-side system configuration file. This improves the configuration update efficiency of the vehicle-side system configuration file and the system stability of the vehicle-side remote upgrade system.

[0046] Example 2

[0047] Figure 2 This is a flowchart of a method for hot-updating vehicle configuration information according to Embodiment 2 of this application. Based on the technical solutions of the above embodiments, this embodiment further refines the step of "performing consistency verification between the vehicle-side system configuration file and the cloud-side system configuration file, and generating a configuration file update task based on the verification result." It should be noted that for parts not detailed in this embodiment, please refer to the relevant descriptions in other embodiments. Figure 2 As shown, the method includes:

[0048] S210. When the target vehicle's on-board remote upgrade system meets the preset update status conditions, a system configuration file verification request is sent to the remote upgrade cloud.

[0049] S220. Based on the verification result of the system configuration file verification request, send a request to the remote upgrade cloud to obtain the cloud system configuration file and obtain the cloud system configuration file.

[0050] S230. Based on the file digest value, for both the vehicle-side system configuration file and the cloud-side system configuration file, verify the file digest value corresponding to the configuration sub-file of the same file type, and take the file type of the configuration sub-file with inconsistent file digest values ​​as the target sub-file type.

[0051] Optionally, in this embodiment of the invention, a configuration sub-file can be used as a single file unit for calculating its file digest value, or multiple configuration sub-files can be used as a multi-file combination unit for calculating their file digest value. For example, for a single file unit, the entire content of the single file unit can be read, and the read content can be input into a preset digest algorithm to output the file digest value corresponding to the single file unit. For a multi-file combination unit, all configuration sub-files existing in the multi-file combination unit can be determined first, and the reading order of the configuration sub-files within the multi-file combination unit can be determined. Following this reading order, the content of each configuration sub-file is read sequentially, and the content of all read configuration sub-files is concatenated into a continuous byte stream. A unique separator is added between the different contents of the configuration sub-files to avoid semantic ambiguity after concatenation. The concatenated continuous byte stream is then input into the preset digest algorithm to determine the file digest value of the multi-file combination unit. It should be noted that when a group of configuration sub-files jointly completes the configuration of a functional module, this group of configuration sub-files can be used as a multi-file combination unit to calculate the overall digest value. Optionally, the preset digest algorithm can be adapted to the needs of those skilled in the art; for example, the preset digest algorithm can be set to the MD5 hash algorithm.

[0052] S240. Generate at least one configuration file update task based on the target sub-file type.

[0053] The configuration file update task can be used to instruct the configuration data of the corresponding configuration subfile in the vehicle system configuration file to be updated based on the configuration subfile of the target subfile type in the cloud system configuration file.

[0054] It should be noted that the vehicle-side system configuration file and the cloud-based system configuration file can be used to control and manage the operation of the vehicle's electronic control units, such as the engine control unit, transmission control unit, brake stability system control unit, body electronic control unit, and autonomous driving assistance control unit; different configuration sub-files are responsible for controlling and managing different electronic control units.

[0055] Specifically, by comparing and verifying the file digest values ​​of configuration sub-files of the same type in the vehicle-side system configuration file and the cloud-side system configuration file, the target sub-file types with different file digest values ​​are determined, and at least one configuration file update task is generated based on the target sub-file type. It should be noted that the target sub-file type indicates that, compared to the vehicle-side system configuration file, the corresponding configuration sub-file of the target sub-file type in the cloud-side system configuration file has been updated, and the configuration data in the corresponding configuration sub-file of the target sub-file type in the cloud-side system configuration file is inconsistent with that in the vehicle-side system configuration file.

[0056] S250: Based on the current task execution status of the target system update task, perform a hot update of the vehicle-side system configuration file according to the configuration file update task.

[0057] Optionally, once the configuration file update task is completed, only a reset of the vehicle-side remote upgrade system is required for the changes to take effect. No system or firmware upgrade of the vehicle-side remote upgrade system is needed. This enhances the flexibility of the vehicle-side remote upgrade system and improves the user experience.

[0058] Optionally, based on the current task execution status of the target system update task, the configuration file update task is performed, including: if there is a target system update task in the vehicle-side remote upgrade system, and the task execution status of the target system update task is "in execution", then it is necessary to wait until the task execution status of the target system update task is "completed" before executing the configuration file update task, so as to perform a hot update of the vehicle-side system configuration file.

[0059] By prioritizing the execution of configuration file update tasks, the stability of system operation is improved.

[0060] This application embodiment performs summary verification on each configuration sub-file in the vehicle-side system configuration file according to the cloud system configuration file, determines the configuration sub-files that have been updated, and generates a configuration file update task based on the updated configuration sub-files. This avoids the need to upgrade the vehicle-side remote upgrade system version at the same time as updating the vehicle-side system configuration file, thus improving the efficiency and flexibility of configuration data updates.

It is applicable to situations where a small number of configuration parameters in the configuration file of a vehicle-side remote upgrade system need to be updated. This vehicle configuration information hot-update device can be implemented in hardware and / or software, and can be configured in a computer device, such as a server. Figure 3 As shown, the device includes:

[0064] The configuration file acquisition module 320 is used to send a cloud system configuration file acquisition request to the remote upgrade cloud based on the verification result of the system configuration file verification request, and acquire the cloud system configuration file.

[0065] The configuration file verification module 330 is used to perform consistency verification on the vehicle-side system configuration file and the cloud system configuration file, and generate a configuration file update task based on the consistency verification result.

[0066] The configuration update module 340 is used to perform a hot update of the vehicle system configuration file by executing the configuration file update task based on the current task execution status of the target system update task; wherein, the target system update task refers to a task that updates the vehicle system configuration file in the vehicle remote upgrade system or a task that performs a system update on the vehicle infotainment system by executing the vehicle remote upgrade system.

[0067] This application embodiment compares whether the vehicle-side system configuration file and the cloud-side system configuration file are consistent. In the case of inconsistency, priority control is used to perform hot updates on the configuration data in the vehicle-side system configuration file based on the configuration data in the cloud-side system configuration file. This improves the configuration update efficiency of the vehicle-side system configuration file and the system stability of the vehicle-side remote upgrade system.

[0068] Optionally, the configuration file verification module 330 includes:

[0069] The target sub-file unit is used to verify the file digest value of the configuration sub-files of the same file type for the vehicle-side system configuration file and the cloud-side system configuration file, respectively, based on the file digest value, and to take the file type of the configuration sub-files with inconsistent file digest values ​​as the target sub-file type;

[0070] A configuration update task unit is configured to generate at least one configuration file update task based on the target sub-file type; wherein, the configuration file update task is configured to instruct the configuration data of the configuration sub-file corresponding to the target sub-file type in the vehicle-side system configuration file to be updated according to the configuration sub-file corresponding to the target sub-file type in the cloud system configuration file.

[0071] Optionally, the vehicle-side system configuration file and the cloud-based system configuration file are used to control and manage the operation of the vehicle's electronic control units; different configuration sub-files are responsible for controlling and managing different electronic control units.

[0072] Optionally, the configuration file verification module 330 includes:

[0074] The configuration storage unit is used to store the cloud system configuration file sent by the remote upgrade cloud to the spare partition of the vehicle-side remote upgrade system after receiving the cloud system configuration file.

[0075] Optionally, the configuration update module 340 may be specifically used to: if the vehicle-side remote upgrade system has a target system update task, and the task execution status of the target system update task is in progress, then it is necessary to wait until the task execution status of the target system update task is completed before executing the configuration file update task, so as to perform a hot update of the vehicle-side system configuration file.

[0076] Optionally, the cloud system configuration file is independently responsible for managing the configuration information of the vehicle-side remote upgrade system, and the file version number of the cloud system configuration file is decoupled from the calibration information of the vehicle's electronic control unit and the vehicle's logistics configuration information.
