[0009] In a possible implementation of the present application, if a target analog-to-digital conversion value matching the operating current value does not exist in the preset current value library, or if a target functional partition corresponding to the target signal value does not exist in the preset signal value library, it includes: not autonomously switching the current software function of the vehicle controller, and reporting a diagnostic fault code, which is used to characterize the existence of an autonomous switching function configuration failure in the vehicle controller.

[0010] In a possible implementation of the present application, if the target load is determined from the replacement load, and the controller of the replacement load is a newly added controller, the method includes: determining a first functional configuration result for the target load based on the operating current value of the target load; determining a second functional configuration result for the target load based on the message identification information of the target load; judging whether the first functional configuration result and the second functional configuration result are consistent; if the first functional configuration result and the second functional configuration result are consistent, autonomously switching the current software function of the vehicle controller to a functional partition corresponding to the first functional configuration result or the second functional configuration result.

[0023] For platform-based modified models, due to inconsistent load parameters, the vehicle controller software needs to re-develop the load function configuration based on different load parameters. Different models require different versions of software, and the vehicle controller software cannot be used on a platform, which increases the cost of software development and management.

[0024] The current configuration switching solutions all require the use of a diagnostic instrument to write configuration words offline, and are unable to switch automatically and adaptively. This increases after-sales costs for manufacturers and increases the time cost of after-sales travel for users. Therefore, in order to solve the above-mentioned problems, an embodiment of the present application provides a solution for the vehicle controller to autonomously switch function configurations, so that the vehicle controller can automatically adapt to the corresponding software according to different vehicle models.

[0025] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0026] Exemplary Methods

[0027] As a first aspect of the present application, the present application provides a method for configuring an autonomous switching function. Figure 1 FIG. 1 is a flow chart of a method for configuring an autonomous switching function provided by an embodiment of the present application. Figure 1 As shown, the method is applied to a vehicle controller, comprising:

[0028] S101, in response to a load change event, obtaining a load change type, wherein the load change type includes replacing a load or adding a load;

[0029] Specifically, the above-mentioned load change events can be used to indicate events in which different loads are changed during the modification process of platform-based vehicle models, including but not limited to adding new loads and replacing loads.

[0030] The so-called load replacement may be to change the driving load, and the type of the corresponding driving load controller does not change, that is, the signal of the bus on the controller does not change.

[0031] The so-called newly added load may be other newly added driving loads on the basis of the existing driving loads, and the switching of some controllers corresponding to the other driving loads involves bus changes.

[0032] In an optional embodiment, in order to cope with different load change events, the load change types can be distinguished in the present application, that is, the load change type can be load replacement or new load addition. Since different load change events involve whether the bus signal on the controller changes, corresponding function configuration strategies can be pre-set for different load change events. Therefore, when the current load changes, the current software function of the vehicle controller can be autonomously switched to the function partition corresponding to the target load through the pre-set function configuration strategy.

[0033] S102, determining a function configuration strategy corresponding to the target load based on the load change type, wherein the function configuration strategy is determined based on the operating current value of the target load, or the function configuration strategy is determined based on the message identification information of the target load, and the message identification information is used to distinguish the controller type of the target load;

[0034] The above-mentioned function configuration strategy can be used to indicate the software function switching of the vehicle controller for the target load based on the load change event.

[0035] It should be noted that the above-mentioned functional configuration strategy is not a fixed strategy, and can be switched accordingly according to the specific load change event. Specifically, if the load change event is to replace the load, the functional configuration strategy of the replaced load can be determined based on the operating current value of the replaced load; if the load change event is to add a new load, the functional configuration strategy of the added load can be determined based on the message identification information of the added load; if the load change event is to change the load, and the switching of some controllers bound to the changed load involves bus changes, the functional configuration strategy of the changed load can be determined based on the operating current value of the changed load, or it can be determined based on the message identification information of the changed load.

[0036] The above-mentioned operating current value can be acquired through the analog-to-digital conversion module inside the vehicle controller, that is, the current value of the target load is acquired through the analog-to-digital conversion module to obtain the above-mentioned operating current value.

[0037] Generally, due to differences in load models, the corresponding load operating current values ​​also vary. Therefore, the load model, operating current value and analog-to-digital conversion value can be associated through a preset truth table, so that the target load can be determined based on the operating current value, thereby realizing the software function partition switching of the target load.

[0038] The above message identification information can be used to distinguish the type of controller that changes the load, that is, different controllers have their corresponding message identifications.

[0039] It should be noted that, during the interaction between the load controller and the bus, the identification information of the interaction message can be filtered to obtain the target interaction message, and the software function partition switching of the target load can be further determined by the target interaction message. Specifically, the message signal value can be obtained by disassembling the target interaction message, and after the vehicle controller detects the message signal value, the control logic can be switched to the software function partition corresponding to the message signal value.

[0040] In an optional embodiment, during the process of platform vehicle model modification, in order to improve the platform adaptability of the vehicle controller software when the electrical load changes, a functional configuration strategy that matches the target load can be determined based on the load change event. Specifically, the target load can be partitioned and functionally configured based on the type of change. Furthermore, if the target load points to a replacement load, the functional configuration strategy for the replacement load is determined based on the operating current value of the replacement load; if the target load points to a new risk, the functional configuration strategy for the new load is determined based on the message identification information of the new load, etc. The present application provides an autonomous switching function configuration strategy so that the software function of the vehicle controller can adaptively adapt to a variety of electrical loads, that is, autonomously switch function partitions based on different electrical loads, realize the platform-based use of the vehicle controller software, and reduce the software development and control costs.

[0041] S103, autonomously partition and switch the software functions of the vehicle controller through the function configuration strategy.

[0042] Specifically, after determining the functional configuration strategy of the target load, the software function of the vehicle controller can be autonomously partitioned and switched. Specifically, since the functional partitions where multiple loads are located can be pre-stored in the vehicle controller chip, each functional partition includes the association between each load and its operating current value and analog-to-digital conversion value, after determining the functional configuration strategy corresponding to the target load, the current software function of the vehicle controller can be autonomously switched to the functional partition corresponding to the target load, so as to achieve the purpose of responding to different load change events. The vehicle controller can autonomously switch the current software function to the functional partition corresponding to the target load without the need for additional software development.

[0043] Based on the above content, the autonomous switching function configuration method provided by the present application includes: in response to a load change event, obtaining a load change type, wherein the load change type includes replacing the load or adding a new load; based on the load change type, determining a function configuration strategy corresponding to the target load, wherein the function configuration strategy is determined based on the operating current value of the target load, or the function configuration strategy is determined based on the message identification information of the target load, and the message identification information is used to distinguish the controller type of the target load; through the function configuration strategy, autonomously partitioning and switching the software functions of the vehicle controller. It is easy to notice that by distinguishing the load change types, when the load change type corresponds to load replacement, the function configuration strategy corresponding to the target load can be determined by the operating current value of the replaced load, and when the load change type corresponds to a newly added load, the function configuration strategy corresponding to the target load can be determined by the message identification information in the newly added load. In this way, in response to different load change events, the vehicle controller can autonomously switch the current software function to the function partition corresponding to the target load without the need for additional software development, thereby realizing the platform-based use of the vehicle controller software, and achieving the technical effect that when the electrical load changes, the vehicle controller autonomously switches the software function of the electrical load to improve the functional configuration efficiency of the electrical load, thereby solving the technical problem of low functional configuration efficiency of the vehicle controller software when the electrical load changes.

[0044] In a possible implementation of the present application, if the target load is determined from the replacement load, based on the load change type, the functional configuration strategy corresponding to the target load is determined, including: collecting the operating current of the replacement load to obtain the operating current value; judging whether there is a target analog-to-digital conversion value that matches the operating current value in the preset current value library, wherein the preset current value library is used to characterize a database that associates preset load operating current values ​​with analog-to-digital conversion values, and the preset current value library supports customized management of load operating current values; if there is a target analog-to-digital conversion value that matches the operating current value in the preset current value library, the target functional configuration strategy corresponding to the target load is determined.

[0045] Specifically, the above-mentioned operating current value can be collected by an analog-to-digital conversion module.

[0046] The above analog-to-digital conversion value can be used to represent the result of converting the analog signal output by the chip into a digital signal.

[0047] The above-mentioned preset current value library can be used to represent a preset database that associates load, operating current value and corresponding analog-to-digital conversion value, and an exemplary reference is made to Table 1:

[0048] Table 1 Preset current value library

[0049] load Current Corresponding analog-to-digital conversion value Load 1 0.1A 500 Load 2 0.2A 1000 Load 3 0.3A 1500

[0050] As shown in Table 1, it can be preset that when the operating current value is 0.1A, the corresponding analog-to-digital conversion value is 500, and the corresponding load is load 1. Similarly, when the operating current value is 0.2A, the corresponding analog-to-digital conversion value is 1000, and the corresponding load is load 2. When the operating current value is 0.3A, the corresponding analog-to-digital conversion value is 1500, and the corresponding load is load 3, etc. Here, each load-current-corresponding analog-to-digital conversion value in the preset current value library is not specifically limited and can be adjusted according to actual conditions.

[0051] In an optional embodiment, when the target load includes a load replaced in a load change event, and the functional configuration strategy is determined based on the operating current value of the target load, the current value of the replaced load can be collected by the analog-to-digital conversion module to obtain the operating current value, and at the same time, based on the preset current value library, it is determined whether there is a target analog-to-digital conversion value that matches the operating current value. If so, the replaced load is functionally configured based on the target analog-to-digital conversion value, that is, the current control logic is switched to the functional partition corresponding to the target load.

[0052] In addition, the above-mentioned preset current value library supports customized management of load operating current values. Specifically, the preset current value library can be managed through a display module such as a large screen or an instrument, including but not limited to deleting or adding values. After the preset current value library is customized, the managed preset current value library can be written into the vehicle controller, and the vehicle controller software can be reset at the same time.

[0053] In a possible implementation of the present application, the method also includes: if there is a target analog-to-digital conversion value that matches the operating current value in the preset current value library, determining a target load associated with the operating current value and the target analog-to-digital conversion value from the replacement load; and autonomously switching the current software function of the vehicle controller to a functional partition corresponding to the target function configuration strategy.

[0054] Specifically, in the switching of hardware current recovery function partitions, since there are multiple replacement loads, but there may be replacement loads that do not have corresponding analog-to-digital conversion values ​​in the preset current value library, it is necessary to determine the target load from the multiple replacement loads and switch the software function of the vehicle controller to the functional partition corresponding to the target load. Specifically, the target load corresponding to the target analog-to-digital conversion value can be determined based on the preset current value library. Exemplarily, as shown in Table 1, if the target analog-to-digital conversion value is 500, the target load is determined to correspond to load 1, if the target analog-to-digital conversion value is 1000, the target load is determined to correspond to load 2, if the target analog-to-digital conversion value is 1500, the target load is determined to correspond to load 3, etc. After determining the target load, the current control logic can be switched to the control logic corresponding to the target load, that is, the software function of the vehicle controller is switched to the functional partition corresponding to the target load.

[0055] Figure 2 FIG. 1 is a flowchart of switching the hardware current recovery function partition according to an embodiment of the present application. Figure 2 As shown, the following steps are included:

[0056] The vehicle controller is powered on and initialized;

[0057] Collect and obtain the operating current value of the replaced load;

[0058] Compare the operating current values ​​using a preset current value library;

[0059] Determine whether there is a corresponding analog-to-digital conversion value of the operating current value in the preset current value library;

[0060] If there is a corresponding analog-to-digital conversion value of the operating current value, the target load is identified; if there is no corresponding analog-to-digital conversion value of the operating current value, the vehicle controller software maintains the status quo and reports a fault diagnostic code;

[0061] The vehicle controller software driver is replaced by different types.

[0062] In a possible implementation of the present application, if the target load is determined from the newly added load, the software function of the vehicle controller is autonomously partitioned and switched through the functional configuration strategy, including: filtering the message identification information of the newly added load to obtain the target identification information, and the target identification information is used to characterize the target controller type corresponding to the target load; disassembling the target interaction message through the target identification information to obtain the target signal value, wherein the target interaction message is used to characterize the message generated by the interaction between the target controller and the bus; judging whether there is a target functional partition corresponding to the target signal value in the preset signal value library, wherein the preset signal value library is used to characterize a database for pre-set custom functional partitioning of the signal value in the message identifier, and the preset signal value library supports custom management of signal values; if there is a target functional partition corresponding to the target signal value in the preset signal value library, the current software function of the vehicle controller is autonomously switched to the target functional partition.

[0063] Specifically, the target identification information mentioned above can be used to indicate the identification information of the interaction message of the desired target controller obtained by filtering.

[0064] Generally, the above-mentioned message identification filtering process can be performed by writing a judgment statement in the vehicle controller, that is, judging whether the current message identification information meets the expected message identification information. If so, the current message identification information is filtered to obtain the target interaction message corresponding to the target identification information.

[0065] The above-mentioned target signal value may be used to represent the original value of the signal in the data field obtained by disassembling the target interaction message.

[0066] Generally, the message disassembly process includes: reading the message, first reading the complete message from the vehicle's communication network (such as CAN, LIN, FlexRay); parsing the message ID to determine the type and source of the message; locating the signal, according to the structure definition of the message, finding the position of each signal in the data field; extracting the signal value, extracting the original value of each signal from the data field.

[0067] The above-mentioned preset signal value library can be used to represent a preset database for customizing functional partitioning of the disassembled signal values, and an exemplary example can be referred to as shown in Table 2:

[0068] Table 2 Preset signal value library

[0069]

[0070] As shown in Table 1, by disassembling the message with the message identification information of 101, multiple signal values ​​of the 0th byte can be obtained. The software function partition of the preset signal value 01 can be function 1, the software function partition of the preset signal value 02 can be function 2, and so on. Here, each signal value-corresponding software function partition in the preset signal value library is not specifically limited and can be adjusted according to actual conditions.

[0071] In an optional embodiment, if the target load is determined from the newly added load, during the process of autonomous partition switching of the software function of the vehicle controller through the functional configuration strategy, since the bus includes multiple messages sent from multiple partial controllers, in order to filter out the desired message from the multiple messages, the identification information of the multiple messages can be filtered to obtain the above-mentioned target identification information, that is, the message information sent by the expected target controller, and then the target interaction message corresponding to the target identification information is disassembled to obtain the target signal value, and compared with the preset signal value library, that is, it is determined whether there is a target function partition corresponding to the target signal value in the preset signal value library. If there is a target function partition corresponding to the target signal value, the current software function of the vehicle controller is autonomously switched to the target function partition.

[0072] In addition, the above-mentioned preset signal value library supports customized management of signal values. Specifically, the preset signal value library can be managed through a display module such as a large screen or an instrument, including but not limited to deleting or adding values. After the preset signal value library is customized, the managed preset signal value library can be written into the vehicle controller, and the vehicle controller software can be reset at the same time.

[0073] Figure 3 FIG. 1 is a flow chart of bus message identification function partition switching provided by an embodiment of the present application, as shown in FIG. Figure 3 As shown, the following steps are included:

[0074] The vehicle controller is powered on and initialized;

[0075] Filter the bus message identifier to obtain the target identifier information;

[0076] Disassemble the target interaction message to obtain the target signal value;

[0077] Determine whether there is a target functional partition corresponding to the target signal value in the preset signal value library;

[0078] If there is a target functional partition corresponding to the target signal value, the vehicle controller software is controlled to switch the partition function. If there is no target functional partition corresponding to the target signal value, the vehicle controller software maintains the status quo and reports a fault diagnostic code.

[0079] In a possible implementation of the present application, if a target analog-to-digital conversion value matching the operating current value does not exist in the preset current value library, or if a target functional partition corresponding to the target signal value does not exist in the preset signal value library, it includes: not autonomously switching the current software function of the vehicle controller, and reporting a diagnostic fault code, which is used to characterize the existence of an autonomous switching function configuration failure in the vehicle controller.

[0080] Specifically, the above-mentioned diagnostic trouble code is a digital universal identifier of a fault state recognized by the on-board diagnostic system, which is used to identify and record the fault occurring in the vehicle.

[0081] In an optional embodiment, as described above Figure 2 or Figure 3 As shown, if there is no target analog-to-digital conversion value matching the operating current value in the preset current value library, or if there is no target function partition corresponding to the target signal value in the preset signal value library, due to incorrect configuration, the vehicle controller cannot be controlled to switch the current software function partition temporarily. At this time, the current software function of the vehicle controller is not switched autonomously, and the diagnostic fault code is reported. By uploading the fault diagnostic code, maintenance personnel can determine the specific fault by reading the diagnostic fault code, and perform fault diagnosis and repair according to the prompt of the fault code.

[0082] In a possible implementation of the present application, if the target load is determined from the replacement load, and the controller of the replacement load is a newly added controller, the method includes: determining a first functional configuration result for the target load based on the operating current value of the target load; determining a second functional configuration result for the target load based on the message identification information of the target load; judging whether the first functional configuration result and the second functional configuration result are consistent; if the first functional configuration result and the second functional configuration result are consistent, autonomously switching the current software function of the vehicle controller to a functional partition corresponding to the first functional configuration result or the second functional configuration result.

[0083] Specifically, the first function configuration result mentioned above can be used to represent the software function partition of the target load obtained by the operating current value of the target load.

[0084] The above-mentioned first function configuration result can be used to represent the software function partition of the target load obtained through the message identification information of the target load.

[0085] In an optional embodiment, based on the above load change event, there may also be a change in the bus involved in the switching of some controllers that replace the load binding. In this case, the target load can be Figure 2 The target load can also be partitioned by switching the hardware current recovery function partition shown in FIG. Figure 3The bus message identification function partition switching method shown is used to obtain the software function partition of the target load, and then the first function configuration result and the second function configuration result mentioned above can be obtained.

[0086] Furthermore, it can be determined whether the first function configuration result and the second function configuration result are consistent. If the first function configuration result and the second function configuration result are consistent, it means that both the hardware current recovery function partition switching method and the line message identification function partition switching method can match the corresponding software function partition of the target load. Therefore, the current software function of the vehicle controller can be autonomously switched to the function partition corresponding to the first function configuration result or the second function configuration result.

[0087] In a possible implementation of the present application, if the first function configuration result and the second function configuration result are inconsistent, the current software function of the vehicle controller is not autonomously switched.

[0088] Specifically, for the above-mentioned result of determining whether the first function configuration result and the second function configuration result are consistent, if the first function configuration result and the second function configuration result are inconsistent, it means that there is a configuration fault in the way the hardware current recovery function partitions are switched, and / or the way the bus message identification function partitions are switched. At this time, the current software function of the vehicle controller may not be switched autonomously, and the diagnostic fault code may be reported. By uploading the diagnostic fault code, maintenance personnel can determine the specific fault by reading the diagnostic fault code, and perform fault diagnosis and repair according to the prompt of the fault code.

[0089] In a possible implementation of the present application, the method further includes: acquiring data storage space inside the vehicle controller chip; and determining the number of partitions of the analog-to-digital conversion value in the preset current value library based on the data storage space.

[0090] Specifically, the above data storage space is determined according to the Flash capacity inside the vehicle controller chip.

[0091] In an optional embodiment, in the process of reserving functional partitions in the preset current value library, the specific number of reserved partitions can be determined according to the Flash capacity inside the vehicle controller chip, that is, the number of reserved partitions does not exceed the maximum data storage space inside the vehicle controller chip.

[0093] As a second aspect of the present application, the present application provides an autonomous switching function configuration system, Figure 4 FIG. 1 is a schematic diagram of an autonomous switching function configuration system provided by an embodiment of the present application. Figure 4 As shown, the system includes:
