[0002] In electric vehicle use, controller upgrades are often required during charging or parking / rest periods. However, current technologies often lack hierarchical and categorized management of controller functions. When a controller is upgraded, some vehicle functions may be interrupted. For example, most vehicle manufacturers stipulate that low-voltage power and terminal communication must be shut down during the upgrade process. This can cause charging interruptions when the controller is being upgraded, severely impacting the driver's and passengers' experience and work efficiency. Summary of the Invention

Detailed Implementation

[0016] The present application will now be described in further detail with reference to the embodiments and accompanying drawings. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the application. Furthermore, it should be noted that, for ease of description, only the parts relevant to the application are shown in the accompanying drawings.

[0017] It should be noted that, unless otherwise specified, the embodiments and features of the embodiments in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0018] The following describes in detail, with reference to the accompanying drawings, a method, system, vehicle, and device for upgrading and optimizing a vehicle controller according to embodiments of this application.

[0019] Figure 1 This is a flowchart of an upgrade and optimization method for a vehicle controller according to an embodiment of this application. Figure 1 As shown, the vehicle controller upgrade and optimization method according to an embodiment of this application includes the following steps: S101: Upon receiving an upgrade request from the target controller, control the vehicle to enter the diagnostic upgrade state.

[0020] The upgrade request process includes: the cloud-based over-the-air (OTA) server detecting that upgrade conditions are met, such as the upgrade package being ready or the scheduled time being reached, and issuing an upgrade request via the TBOX; the driver confirming whether to allow the upgrade via the central control screen or mobile phone; and the local diagnostic tool triggering a diagnostic upgrade at the vehicle's diagnostic interface. Specifically, if the controller to be upgraded is a different domain controller or belongs to a different domain controller, simultaneous local and cloud-based diagnostic upgrade operations are supported.

[0021] In one embodiment of this application, the step of controlling the vehicle to enter the diagnostic upgrade state after receiving the upgrade request from the target controller includes: waking up the central domain controller after receiving the upgrade request from the target controller; and identifying and maintaining the vehicle in a state that allows diagnostic upgrades through the central domain controller.

[0022] Specifically, when upgrades are permitted, the TBOX or local diagnostic tool wakes up the central domain controller, which is in a dormant state. Based on the conditions of the target controller to be upgraded, such as whether it supports sleep wake-up, whether it supports high and low voltage upgrades, and whether the vehicle speed is less than the preset speed, the central domain controller identifies and maintains the vehicle in a state that allows diagnostic upgrades, such as whether it is in a low voltage state, whether it is in a high voltage state, whether the parking brake is engaged, and whether the drive torque is 0.

[0023] S102: Receive a function addressing instruction sent by TBOX or local diagnostic instrument, and determine the first domain controller according to the function addressing instruction, wherein the first domain controller is the central domain controller or area controller to which the target controller belongs.

[0024] In one embodiment of this application, before receiving the function addressing instruction sent by the TBOX or local diagnostic instrument and determining the first domain controller according to the function addressing instruction, the method further includes: obtaining the central domain controller or area controller to which the target controller belongs through the TBOX or local diagnostic instrument; and generating a corresponding function addressing instruction according to the central domain controller or area controller.

[0025] Combination Figure 2 As shown, different domain controllers correspond to different function addressing instructions based on their addresses. For example, if the target controller is under ZCUF, the function addressing instruction is "TBOX_FuncDiag: 0x18DBFFF9"; if the target controller is under ZCUFL, the function addressing instruction is "TBOX_FuncDiag: 0x18DBFFFA"; if the target controller is under ZCUFR, the function addressing instruction is "TBOX_FuncDiag: 0x18DBFFFB"; if the target controller is under ZCUR, the function addressing instruction is "TBOX_FuncDiag: 0x18DBFFFC"; and if the target controller is under CCU, the function addressing instruction is "TBOX_FuncDiag: 0x18DBFFFE".

[0026] Furthermore, the function addressing instructions determined in the above process are sent to the central domain controller, which can then parse them to determine whether the target controller belongs to the central domain controller or the area controller.

[0027] S103: During the upgrade process, the central domain controller is prohibited from sending communication control services, and the diagnostic fault recording function of the first domain controller and its subordinate controllers is disabled.

[0028] In one embodiment of this application, the step of prohibiting the central domain controller from sending communication control services and disabling the diagnostic fault recording function of the first domain controller and its subordinate controllers during the upgrade process includes: prohibiting the central domain controller from sending communication control services to any network segment; and forwarding diagnostic fault recording control instructions to the first domain controller and its subordinate controllers to disable the diagnostic fault recording function of the first domain controller and its subordinate controllers.

[0029] Specifically, to prevent communication shutdown from affecting normal function, the central domain controller is prohibited from sending 0x28 communication control services to any network segment. At the same time, the central controller forwards the 0x85 diagnostic fault recording control command issued by the TBOX or local diagnostic instrument to the first domain controller and its subordinate controllers to temporarily disable its diagnostic fault recording function in order to prevent the fault code from being triggered accidentally during the upgrade process.

[0030] S104: Determine whether the upgrade process affects the function execution of the target controller. If so, prohibit the second domain controller from diagnosing fault records for this function. The second domain controller is a region controller other than the first domain controller.

[0031] In one embodiment of this application, determining whether the upgrade process affects the function execution of the target controller, and if so, prohibiting the second domain controller from recording diagnostic faults for that function, includes: determining whether the upgrade process affects the function execution of the target controller; if so, sending an upgrade process notification instruction to the second domain controller to prohibit the second domain controller from recording diagnostic faults for that function.

[0032] Specifically, if the central domain controller determines that the upgrade process affects the functional execution of the target control area, it sends an upgrade progress notification instruction to the second domain controller, for example, in conjunction with... Figure 2 If the EPS is the target controller, when the upgrade process affects the function execution of the EPS, the central domain controller sends the “CCU_ECUUpgradePrecessing” command to the area controllers ZCUFL, ZCUFR, and ZCUR, which are all other than the area controller ZCUF to which the EPS belongs, indicating that the relevant operation is related to the upgrade of the EPS and that fault recording for this function is prohibited; functions unrelated to the target controller are recorded normally for fault diagnosis.

[0033] In one embodiment of this application, the method further includes: if the communication load rate of any network segment is greater than a predetermined benchmark, or if the number of consecutively lost message frames is greater than or equal to a predetermined number of frames, then the data transmission rate is reduced.

[0034] In a specific example, the communication load rate of each network segment is monitored in real time. If the communication load rate of any network segment is >70%, or if three or more critical packets are lost consecutively, a flow control frame to reduce the continuous frame transmission is sent to the TBOX or local diagnostic instrument to reduce the data transmission rate.

[0035] In addition, to improve efficiency, a flow control frame that speeds up the transmission of consecutive frames can be sent. If the load is detected to be overloaded again or frames are dropped, the parameters of the previous flow control frame will be restored and no further attempts will be made to speed up the transmission of consecutive frames.

[0036] In one embodiment of this application, the method further includes: after the upgrade is completed, forwarding a diagnostic fault record control command to the first domain controller and its subordinate controllers to restore the diagnostic fault record function; restoring the vehicle to its state before the upgrade and providing an upgrade completion notification.

[0037] Among them, restoring the vehicle to its pre-upgrade state, such as hibernation, charging, or parking with the air conditioning on, will report the upgrade success to the OTA server via TBOX, or the local diagnostic tool will pop up a message indicating that the upgrade is complete.

[0038] According to the vehicle controller upgrade optimization method of this application embodiment, firstly, after receiving an upgrade request from the target controller, the vehicle is controlled to enter a diagnostic upgrade state; secondly, a function addressing instruction sent by a TBOX or local diagnostic tool is received, and a first domain controller is determined according to the function addressing instruction, wherein the first domain controller is the central domain controller or regional controller to which the target controller belongs; during the upgrade process, the central domain controller is prohibited from sending communication control services, and the diagnostic fault recording function of the first domain controller and its subordinate controllers is disabled; finally, it is determined whether the upgrade process affects the function execution of the target controller. If so, the second domain controller is prohibited from performing diagnostic fault recording for this function, wherein the second domain controller is a regional controller other than the first domain controller. Therefore, during the upgrade process, by disabling the diagnostic fault recording function of regional controllers and allowing other domain controllers to function normally when the controller function is malfunctioning, false alarms can be avoided, function interruptions can be prevented, and system efficiency can be improved.

[0039] Figure 3 This is a structural block diagram of a vehicle controller upgrade and optimization system according to an embodiment of this application. Figure 3 As shown, an upgrade and optimization system for a vehicle controller according to an embodiment of this application includes: a receiving module 310, an addressing module 320, a control module 330, and a judging module 340, wherein: The receiving module 310 is used to control the vehicle to enter the diagnostic upgrade state after receiving an upgrade request from the target controller. Addressing module 320 is used to receive the domain controller address sent by TBOX or local diagnostic instrument, and determine the first domain controller according to the domain controller address, wherein the first domain controller is the central domain controller or area controller where the target controller is located; During the upgrade process, the control module 330 prohibits the central domain controller from sending communication control services and disables the diagnostic fault recording function of the first domain controller and its subordinate controllers. The judgment module 340 determines whether the upgrade process affects the function execution of the target controller. If so, it prohibits the second domain controller from diagnosing fault records for this function. The second domain controller is a region controller other than the first domain controller.

[0040] According to the vehicle controller upgrade and optimization system of this application embodiment, firstly, upon receiving an upgrade request from the target controller, the system controls the vehicle to enter a diagnostic upgrade state; secondly, it receives a function addressing instruction sent by a TBOX or local diagnostic tool, and determines the first domain controller based on the function addressing instruction, wherein the first domain controller is the central domain controller or regional controller to which the target controller belongs; during the upgrade process, the central domain controller is prohibited from sending communication control services, and the diagnostic fault recording function of the first domain controller and its subordinate controllers is disabled; finally, it is determined whether the upgrade process affects the function execution of the target controller. If so, the second domain controller is prohibited from performing diagnostic fault recording for that function, wherein the second domain controller is a regional controller other than the first domain controller. Therefore, by disabling the diagnostic fault recording function of regional controllers during the upgrade process, and allowing other domain controllers to function normally when the controller's function malfunctions, false alarms can be avoided, function interruptions can be prevented, and system efficiency can be improved.

If so, the second domain controller is prohibited from performing diagnostic fault recording for that function, wherein the second domain controller is an area controller other than the first domain controller.
