[0049] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0050] In one embodiment, Figure 1 As shown, a controller joint upgrade method is provided. This embodiment uses the method applied to a target controller as an example. In this embodiment, the method includes the following steps:

[0051] Step 102: Send an upgrade instruction to the upgrade diagnostic device, where the upgrade instruction is used by the upgrade diagnostic device to determine upgrade file identifiers of at least two vehicle controllers; the at least two vehicle controllers include a target controller and an associated controller, and the target controller and the associated controller process a vehicle function request in an interactive processing manner, where the vehicle function request is used to request provision of a vehicle function;

[0052] The controller joint upgrade of the present application is mainly realized through the interaction between the target controller and the upgrade diagnostic device. The target controller sends an upgrade instruction to the upgrade diagnostic device, and the upgrade diagnostic device determines the upgrade file identifiers of at least two vehicle controllers based on the upgrade instruction;

[0053] In this embodiment, any vehicle controller has multiple versions of configuration upgrade files, and the multiple versions of configuration upgrade files correspond to different upgrade file identifiers. After determining the upgrade file identifier based on the upgrade instruction, the configuration upgrade file version corresponding to the upgrade file identifier can be determined.

[0054] Wherein, the upgrade diagnostic device determines the upgrade file identifiers of at least two vehicle controllers based on the upgrade instruction, including: the upgrade instruction carries the upgrade file identifiers of at least two vehicle controllers, so that the upgrade diagnostic device can directly determine the upgrade file identifiers of at least two vehicle controllers carried in the upgrade instruction;

[0055] Alternatively, the upgrade instruction carries the controller identifications of at least two vehicle controllers, so that the upgrade diagnostic device determines the upgrade file identifications of at least two vehicle controllers based on the controller identifications of at least two vehicle controllers carried in the upgrade instruction;

[0056] Alternatively, the upgrade diagnostic device pre-stores the upgrade file identifier of each controller, and the association relationship between the upgrade file identifier of the controller and the upgrade file identifier of an associated controller of the controller, the upgrade instruction carries the upgrade file identifier of the target vehicle controller, and the upgrade diagnostic device determines the upgrade file identifier of the associated controller based on the upgrade file identifier of the target vehicle controller and the association relationship, and uses the upgrade file identifier of the target vehicle controller and the upgrade file identifier of the associated controller as the upgrade file identifiers of at least two vehicle controllers;

[0057] Alternatively, the upgrade diagnostic device pre-stores the controller identifier of each controller, as well as the association between the controller identifier of the controller and the controller identifier of the associated controller of the controller, the upgrade instruction carries the controller identifier of the target vehicle controller, the upgrade diagnostic device determines the controller identifier of the associated controller based on the controller identifier and the association relationship, determines the upgrade file identifier of the target vehicle controller based on the controller identifier of the target vehicle controller, determines the upgrade file identifier of the associated vehicle controller based on the controller identifier of the associated vehicle controller, and uses the upgrade file identifier of the target vehicle controller and the upgrade file identifier of the associated controller as the upgrade file identifiers of at least two vehicle controllers.

[0058] In this embodiment, there will be functional linkage between vehicle controllers. A certain vehicle function requires signal interaction between controllers to be implemented, so the versions of the controllers need to match to realize the normal functions of the controllers.

[0059] The relationship between the target controller and the associated controller is: a vehicle function request received through the vehicle machine interface requires one or more interactive processes between the target controller and the associated controller to realize the vehicle function requested by the vehicle function request.

[0060] A possible scenario for the interaction between the target controller and the associated controller to process vehicle function requests is: the target controller obtains processed data after processing the vehicle function request, and the target controller sends the processed data to the associated controller for further processing to complete the processing of the vehicle function request; or the associated controller obtains processed data after processing the vehicle function request, and the associated controller sends the processed data to the target controller for further processing to complete the processing of the vehicle function request.

[0061] Step 104, receiving the configuration upgrade files corresponding to the upgrade file identifiers sent by the upgrade diagnostic device, and using the configuration upgrade files corresponding to the upgrade file identifiers as the configuration upgrade files of the vehicle controller corresponding to the upgrade file identifiers;

[0062] An upgrade file identifier corresponds to a configuration upgrade file, and the configuration upgrade file includes various configuration data required for the controller to perform a version upgrade.

[0063] Step 106: Perform configuration upgrade based on the configuration upgrade file of the target controller, and send the configuration upgrade file of the associated controller to the associated controller to instruct the associated controller to perform configuration upgrade based on the configuration upgrade file of the associated controller.

[0064] The target controller itself performs configuration upgrade based on the configuration upgrade file of the target controller, thereby completing the version upgrade of the target controller. At the same time, the target controller sends the configuration upgrade file of the associated controller to the associated controller, so that the associated controller can perform configuration upgrade based on the configuration upgrade file of the associated controller. In this way, both the target controller and the associated controller can complete the configuration upgrade, thereby realizing the joint upgrade of the target controller and the associated controller.

[0065] It can be seen that after sending the upgrade instruction to the upgrade diagnostic device, the upgrade instruction is used by the upgrade diagnostic device to determine the upgrade file identifiers of at least two vehicle controllers, the at least two vehicle controllers include a target controller and an associated controller, the target controller and the associated controller process vehicle function requests through interactive processing, the vehicle function request is used to request the provision of vehicle functions, that is, the same vehicle function requires interactive processing between the target controller and the associated controller to be realized, after receiving the configuration upgrade files corresponding to each upgrade file identifier sent by the upgrade diagnostic device, the configuration upgrade file corresponding to the upgrade file identifier is used as the configuration upgrade file of the vehicle controller corresponding to the upgrade file identifier, and then the configuration upgrade is performed based on the configuration upgrade file of the target controller, and the configuration upgrade file of the associated controller is sent to the associated controller to instruct the associated controller to perform the configuration upgrade based on the configuration upgrade file of the associated controller, thereby realizing the configuration upgrade of the target controller and the configuration upgrade of the associated controller, realizing the joint upgrade of the configurations of at least two controllers, thereby ensuring that the configurations of at least two controllers match, and the target controller and the associated controller perform interactive processing normally to realize the vehicle function, thereby improving the user experience and ensuring the vehicle safety.

[0066] In one of the embodiments, after performing the configuration upgrade based on the configuration upgrade file of the target controller and sending the configuration upgrade file of the associated controller to the associated controller, the method further includes: determining the upgrade progress of the at least two vehicle controllers; determining the overall upgrade progress based on the upgrade progress of the at least two controllers; and feeding back the overall upgrade progress to the upgrade diagnostic device.

[0067] In one embodiment, determining the upgrade progress of the at least two vehicle controllers includes: determining the unit upgrade progress of at least two control units in the vehicle controller for each vehicle controller; correspondingly, determining the overall upgrade progress based on the upgrade progress of the at least two controllers includes: based on the unit upgrade progress corresponding to each vehicle controller, counting the unit upgrade progress of the same control unit to obtain the unit upgrade progress corresponding to each control unit; determining the target unit upgrade progress of each control unit from the unit upgrade progress corresponding to each control unit; and obtaining the overall upgrade progress based on the target unit upgrade progress corresponding to each control unit and the weight corresponding to each control unit.

[0068] Each vehicle controller includes at least two control units, which may be a system on chip (SoC) and a microcontroller unit (MCU). For each vehicle controller, it is necessary to determine the upgrade progress of the SoC and the upgrade progress of the MCU.

[0069] Based on the upgrade progress of the SOC and the upgrade progress of the MCU corresponding to each vehicle controller, the unit upgrade progress of the MCU is counted to obtain the unit upgrade progress corresponding to the MCU in each vehicle controller, and the target unit upgrade progress of the MCU is determined from the unit upgrade progress corresponding to the MCU in multiple vehicle controllers; the target unit upgrade progress of the SOC is determined from the unit upgrade progress corresponding to the SOC in multiple vehicle controllers;

[0070] Based on the target unit upgrade progress corresponding to the MCU, the target unit upgrade progress corresponding to the SOC, the weight corresponding to the MCU, and the weight corresponding to the SOC, the overall upgrade progress is obtained.

[0071] The step of determining the target unit upgrade progress of the MCU from the unit upgrade progresses corresponding to the MCUs in the multiple vehicle controllers includes: determining the minimum unit upgrade progress from the unit upgrade progresses corresponding to the MCUs in the multiple vehicle controllers, and using the minimum unit upgrade progress as the target unit upgrade progress of the MCU;

[0072] Among them, determining the target unit upgrade progress of SOC from the unit upgrade progresses corresponding to SOC in multiple vehicle controllers includes: determining the minimum unit upgrade progress from the unit upgrade progresses corresponding to SOC in multiple vehicle controllers, and determining the target unit upgrade progress of SOC based on the minimum unit upgrade progress.

[0073] One scenario of this embodiment is:

[0074] The weight of SOC refresh progress is 80%, and the weight of MCU refresh progress is 20%;

[0075] Determine the first minimum value of the refresh progress of the SOC of controller 1 and the refresh progress of the SOC of controller 2, and the second minimum value of the refresh progress of the MCU of controller 1 and the refresh progress of the MCU of controller 2, and add the first minimum value and the second minimum value to report, as shown in the following example:

[0076] When the SOC upgrade progress of controller 1 is 50% and the SOC upgrade progress of controller 2 is 40%, the MCU upgrade progress of controller 1 and controller 2 are both 0%, and the total progress is 32% = 40% * 80%;

[0077] After the SOC upgrade of controller 1 and controller 2 is completed, the MCU upgrade progress of controller 1 is 50%, and the MCU upgrade progress of controller 2 is 60%; the total progress is 90% = 80% + 50% * 20%.

[0078] In one of the embodiments, determining the unit upgrade progress of at least two control units in the vehicle controller includes: sending a progress acquisition instruction to the associated controller; receiving the unit upgrade progress of at least two control units in the associated controller sent by the associated controller based on the progress acquisition instruction.

[0079] For the target controller, the target vehicle controller may determine the unit upgrade progress of at least two control units of the target vehicle controller;

[0080] For the associated controller, the target controller sends a progress acquisition instruction to the associated controller through the scalable service-oriented middleware over IP (someip) protocol. After receiving the progress acquisition instruction, the associated controller feeds back the unit upgrade progress of at least two control units of the vehicle controller to the target controller through the someip protocol.

[0081] The upgrade diagnostic device sends a unified diagnostic services (UDS) protocol 22 service instruction to the target controller to read the installation status of the target controller until the installation is completed. The target controller then feeds back the verification results to the upgrade diagnostic device. The installation status indicates the overall upgrade progress of the target controller and associated controllers.

[0082] In one of the embodiments, using the configuration upgrade file corresponding to the upgrade file identifier as the configuration upgrade file of the vehicle controller corresponding to the upgrade file identifier includes: performing integrity check and consistency check on the configuration upgrade files corresponding to each upgrade file identifier; when all checks pass, using the configuration upgrade file corresponding to the upgrade file identifier as the configuration upgrade file of the vehicle controller corresponding to the upgrade file identifier.

[0083] The upgrade diagnostic device sends UDS protocol 31 service instructions to the target controller to perform routine control on the target controller. The target controller performs integrity and consistency checks on the configuration upgrade files corresponding to each upgrade file identifier, for example, verifying the integrity and consistency of the configuration upgrade file corresponding to the upgrade file identifier of the target controller, and verifying the integrity and consistency of the configuration upgrade file corresponding to the upgrade file identifier of the associated controller.

[0084] If the configuration upgrade file corresponding to the upgrade file identifier of the target controller passes both the integrity check and the consistency check, the configuration upgrade file is used as the configuration upgrade file of the target controller;

[0085] When the integrity check and consistency check of the configuration upgrade file corresponding to the upgrade file identifier of the associated controller are passed, the configuration upgrade file is used as the configuration upgrade file of the associated controller.

[0086] In one embodiment, performing a configuration upgrade based on a configuration upgrade file of a target controller, and sending a configuration upgrade file of an associated controller to an associated controller to instruct the associated controller to perform a configuration upgrade based on the configuration upgrade file of the associated controller, includes:

[0087] The upgrade diagnosis device sends a UDS protocol 31 service instruction to the target controller, performs routine control on the target controller, starts the routine, and the target controller performs configuration upgrade based on the configuration upgrade file of the target controller;

[0088] The target controller sends the configuration upgrade file of the associated controller to the associated controller through the internal protocol, and after the transmission is completed, the target controller and the associated controller each perform a software upgrade action. The internal protocol may be a network file system (NFS) protocol.

[0089] In one of the embodiments, after the overall upgrade progress is fed back to the upgrade diagnostic device, the method further includes: receiving an operation instruction sent by the upgrade diagnostic device, the operation instruction including at least one of an instruction to clear a fault code or a reset instruction sent by the upgrade diagnostic device after determining that the overall upgrade progress meets a preset progress condition; performing corresponding operations on the target controller based on the operation instruction, and sending the operation instruction to the associated controller to instruct the associated controller to perform corresponding operations on the associated controller based on the operation instruction.

[0090] For the scenario where the operation instruction is to clear the fault code, the application scheme is:

[0091] The upgraded diagnostic device sends a UDS protocol 14 service command to the target controller, namely, a clear fault code command, which is used to clear the fault code. After the target controller receives the clear fault code command, the controller needs to clear the fault code.

[0092] At the same time, the target controller needs to send a clear fault code instruction to the MCU of the target controller, and the MCU then sends the clear fault code instruction to the associated controller through the diagnostic controller area network identifier (CAN ID) of the associated controller to clear the fault code.

[0093] For the scenario where the operation instruction is a reset instruction, the application solution is:

[0094] After determining that the overall upgrade progress is greater than a preset progress threshold, the upgrade diagnostic device sends a UDS protocol 11 service instruction to the target controller, and the controller is reset. After receiving the reset instruction, the target controller sends the reset instruction to the MCU and SOC of the target controller through an internal protocol to perform a restart action; the internal protocol may be an inter-process communication (IPC) protocol;

[0095] At the same time, the target controller also needs to send the reset instruction to the associated controller through the internal protocol (the internal protocol can be the someip protocol). After receiving the reset instruction, the associated controller sends it to the MCU and SOC of the associated controller through the internal IPC protocol to execute the restart action.

[0096] In one of the embodiments, receiving the configuration upgrade files corresponding to each upgrade file identifier sent by the upgrade diagnostic device includes: receiving the file path of the configuration upgrade file sent by the upgrade diagnostic device; and receiving the configuration upgrade files corresponding to each upgrade file identifier sent by the upgrade diagnostic device through the file path.

[0097] The upgrade diagnostic device sends a UDS protocol 38 service instruction to the target controller, providing the target controller with a file path and file size of a configuration upgrade file;

[0098] The upgrade diagnostic device sends a UDS protocol 36 service instruction to the target controller, and transmits the configuration upgrade file of each vehicle controller to the target controller;

[0099] After the upgrade diagnostic device determines that the configuration upgrade file transmission is completed, it sends a UDS protocol 37 service instruction to the target controller to exit the transmission of the configuration upgrade file;

[0100] The target controller receives the configuration upgrade files corresponding to the upgrade file identifiers sent by the upgrade diagnosis device through the file path.

[0101] In one embodiment, as shown in FIG2 , a controller joint upgrade method is provided. This embodiment uses the method applied to upgrade a diagnostic device as an example. In this embodiment, the method includes the following steps:

[0102] Step 202: receiving an upgrade instruction sent by a target controller;

[0103] Step 204: determining upgrade file identifiers of at least two vehicle controllers based on the upgrade instruction; the at least two vehicle controllers include a target controller and an associated controller, the target controller and the associated controller process a vehicle function request through an interactive processing manner, and the vehicle function request is a request for providing a vehicle function;

[0104] Step 206: Send the configuration upgrade file corresponding to each upgrade file identifier to the target controller to instruct the target controller to use the configuration upgrade file corresponding to the upgrade file identifier as the configuration upgrade file of the vehicle controller corresponding to the upgrade file identifier; perform configuration upgrade based on the configuration upgrade file of the target controller, and send the configuration upgrade file of the associated controller to the associated controller, and the configuration upgrade file of the associated controller is used for the associated controller to perform configuration upgrade.

[0105] The specific implementation of the steps in this embodiment is the same as above Figure 1 The steps of the illustrated embodiments are similar and are substantially the same technical solutions, which will not be described in detail here.

[0106] It can be seen that after receiving the upgrade instruction sent by the target controller, based on the upgrade instruction, the upgrade file identifiers of at least two vehicle controllers can be determined; the at least two vehicle controllers include a target controller and an associated controller, and the target controller and the associated controller process vehicle function requests through interactive processing. The vehicle function request is a request for providing vehicle functions, that is, the same vehicle function requires interactive processing between the target controller and the associated controller to be realized, and the configuration upgrade file corresponding to each upgrade file identifier is sent to the target controller to instruct the target controller to use the configuration upgrade file corresponding to the upgrade file identifier as the configuration upgrade file of the vehicle controller corresponding to the upgrade file identifier; configuration upgrade is performed based on the configuration upgrade file of the target controller, and the configuration upgrade file of the associated controller is sent to the associated controller, and the configuration upgrade file of the associated controller is used for the associated controller to perform configuration upgrade, thereby realizing the joint upgrade of the configurations of at least two controllers, thereby ensuring that the configurations of at least two controllers match, and the target controller and the associated controller perform normal interactive processing to realize vehicle functions, thereby improving user experience and ensuring vehicle safety.

[0107] In summary, in the existing solutions, there will be functional linkage between vehicle controllers. A certain vehicle function requires signal interaction between controllers to be realized, so the versions (or configurations) between controllers need to match to realize the normal functions of the controllers. The software version updates and iterations of the on-board controllers may be frequent and complicated. If only one controller is upgraded, it will cause the controller version (or configuration) to mismatch, resulting in the inability to think of vehicle functions, affecting the reliability of vehicle functions and user experience.

[0108] The present application provides a controller joint upgrade method. When a controller needs to be upgraded, the associated controller is upgraded synchronously. The upgrade diagnostic device exchanges data with the target controller to achieve unified software upgrade of the target controller and the associated controller. The specific process of the controller joint upgrade method of the present application is as follows:

[0109] Step 1: The upgraded diagnostic device (corresponding to the diagnostic instrument in the figure) establishes a diagnostic communication connection with the vehicle through the on-board diagnostic system (OBD) interface, and performs diagnostic communication with the target controller based on the diagnostic communication protocol over internet protocol (DoIP);

[0110] The process includes three stages: before flashing, during flashing, and after flashing. Before flashing corresponds to steps 2 to 4, during flashing corresponds to steps 5 to 13, and after flashing corresponds to steps 14 to 19;

[0111] Step 2: The upgrade diagnostic device sends a UDS protocol diagnostic session instruction to the target controller, executes 10 service function addressing, and the target controller enters the extended session;

[0112] Step 3: The upgrade diagnostic device sends a UDS protocol 85 service instruction to the target controller, executes the 85 service function addressing, stops updating the diagnostic trouble code (DTC) status of the target controller, and supports the subsequent shutdown of the sending and receiving of network communication messages and network management message information, so as to prevent the DTC from being incorrectly recorded due to the fault triggered by the flashing operation during the controller upgrade process;

[0113] Step 4: The upgrade diagnostic device sends the UDS protocol 28 service instruction to the target controller to close the sending and receiving of network communication messages and network management message information. During the controller upgrade process, by executing the 28 service function addressing, the sending and receiving of bus application messages and network management messages can be suppressed to reduce the network bus load, reduce communication interference, ensure the smooth transmission of key data, and improve the overall communication efficiency.

[0114] Step 5: The upgrade diagnostic device sends a UDS protocol diagnostic session instruction to the target controller, and the target controller switches the session and enters the programming session;

[0115] Step 6: The upgrade diagnostic device sends a UDS protocol 27 service instruction to the target controller, and the target controller passes the corresponding level of security access;

[0116] Step 7: The upgrade diagnostic device sends a UDS protocol 2E service instruction to the target controller, and the target controller writes specific information: the diagnostic device serial number and installation date, and records the controller upgrade record;

[0117] Step 8: The upgrade diagnostic device sends a UDS protocol 38 service instruction to the target controller, providing information such as the controller flash file path and file size, where the flash file is the configuration upgrade file of the controller;

[0118] Step 9: The upgrade diagnostic device sends a UDS protocol 36 service instruction to the target controller to transfer the flash file;

[0119] Step 10: After the upgrade diagnostic device determines that the configuration upgrade file transfer is complete, it sends a UDS protocol 37 service instruction and exits the file transfer;
