[0070] Based on the above hardware structure, an embodiment of the vehicle fault information processing method of the present invention is proposed.

[0071] Reference Figure 2 , Figure 2 This is a flowchart illustrating the first embodiment of the vehicle fault information processing method of the present invention.

[0072] In the first embodiment, the vehicle fault information processing method includes the following steps:

[0073] Step S10: Obtain the vehicle information and ECU characteristic data of the current vehicle and the electronic control unit (ECU), and generate a characteristic list based on the vehicle information and the ECU characteristic data.

[0074] It should be noted that the system obtains the current vehicle information and the characteristic data of the Electronic Control Unit (ECU), and then generates a characteristic list based on the vehicle information and the ECU characteristic data.

[0075] Step S20: Generate the structure of the current vehicle based on the characteristic list.

[0076] It is understandable that a structural diagram of each component unit object in the current vehicle can be generated based on the aforementioned feature list.

[0077] Step S30: Generate a fault list based on the structure, and process the faults of the current vehicle based on the fault list.

[0078] It should be understood that a fault list can be generated based on the structure diagram, and then the faults of the corresponding component unit objects in the current vehicle can be processed according to the fault list.

[0079] This embodiment, through the above-described scheme, obtains the vehicle information and ECU characteristic data of the current vehicle, generates a characteristic list based on the vehicle information and ECU characteristic data, generates the structure of the current vehicle based on the characteristic list, generates a fault list based on the structure, and processes the faults of the current vehicle based on the fault list. This approach can more intuitively reflect the fault status of the current product, reduce the processing difficulty of vehicle fault information processing methods, better process fault information according to the design object, solve the problems of poor software reusability and scalability, simplify method code maintenance, and improve the speed and efficiency of vehicle fault information processing.

[0080] Furthermore, Figure 3 This is a flowchart illustrating the second embodiment of the vehicle fault information processing method of the present invention, as shown below. Figure 3 As shown, based on the first embodiment, a second embodiment of the vehicle fault information processing method of the present invention is proposed. In this embodiment, step S10 specifically includes the following steps:

[0081] Step S11: Obtain the current vehicle information and the ECU characteristic data of the electronic control unit (ECU).

[0082] It should be noted that the data acquisition unit can acquire the current vehicle information and the ECU characteristic data of the electronic control unit (ECU). The data acquisition unit can be an on-board data acquisition unit or an independent data acquisition unit or device.

[0083] Step S12: Extract relevant data related to the fault diagnosis results and on-board instrument display content of the current vehicle from the vehicle information and the ECU characteristic data, and generate a characteristic list based on the relevant data.

[0084] It is understood that relevant data related to the fault diagnosis results of the current vehicle and the content displayed on the vehicle instrument panel can be extracted from the vehicle information and the ECU characteristic data, and a characteristic list can be generated based on the relevant data.

[0085] This embodiment, through the above-described scheme, obtains the current vehicle information and ECU characteristic data of the electronic control unit (ECU); extracts relevant data related to the current vehicle's fault diagnosis results and the content displayed on the vehicle's instrument panel from the vehicle information and ECU characteristic data; and generates a characteristic list based on the relevant data. This can more intuitively reflect the current product's fault status and reduce the operational difficulty of vehicle fault information processing methods.

[0086] Furthermore, Figure 4 This is a flowchart illustrating the third embodiment of the vehicle fault information processing method of the present invention, as shown below. Figure 4 As shown, based on the second embodiment, a third embodiment of the vehicle fault information processing method of the present invention is proposed. In this embodiment, step S12 specifically includes the following steps:

[0087] Step S121: Obtain the fault code corresponding to the current vehicle's fault diagnosis result, and obtain the fault information corresponding to the content displayed on the vehicle's instrument panel.

[0088] It should be noted that, while obtaining the fault code corresponding to the current vehicle's fault diagnosis result, it is also possible to obtain the fault information corresponding to the content displayed on the vehicle's instrument panel.

[0089] Step S122: Extract relevant data related to the fault code and the fault information from the vehicle information and the ECU characteristic data, and generate a characteristic list based on the relevant data.

[0090] It is understood that relevant data related to the fault codes and fault information can be extracted from the vehicle information and the ECU characteristic data, and then a characteristic list can be generated based on the relevant data.

[0091] In practice, by sorting out the requirements of the whole vehicle and ECU, and based on the requirements related to fault handling, a feature list is extracted from the perspective of software maintenance convenience.

[0092] This embodiment, through the above-described scheme, obtains the fault code corresponding to the current vehicle's fault diagnosis result and the fault information corresponding to the content displayed on the vehicle's instrument panel; extracts relevant data related to the fault code and the fault information from the vehicle information and the ECU characteristic data, and generates a characteristic list based on the relevant data; it can more intuitively reflect the current product's fault status and reduce the operational difficulty of vehicle fault information processing methods.

[0093] Furthermore, Figure 5 This is a flowchart illustrating the fourth embodiment of the vehicle fault information processing method of the present invention, as shown below. Figure 5 As shown, based on the first embodiment, a fourth embodiment of the vehicle fault information processing method of the present invention is proposed. In this embodiment, step S20 specifically includes the following steps:

[0094] Step S21: Obtain the attributes of each attribute object in the attribute list, and create several instances based on the attributes.

[0095] It should be noted that the attributes of each characteristic object in the characteristic list are obtained. The attributes correspond to different fault behaviors, including but not limited to short circuit, open circuit, over-temperature, message timeout, etc. Several instances can be created according to the above description.

[0096] Step S22: Determine the structure variables based on the instance, unify the format of the attribute characteristics of each characteristic object in the current vehicle based on the structure variables, and generate the structure of each characteristic object.

[0097] It is understandable that, based on the example, the structure variables are determined, and then the structure of each characteristic object is generated based on the unified format of the structure variables, that is, the unified format of the attribute characteristics of each characteristic object in the current vehicle.

[0098] In the specific implementation, a suitable structure can be designed based on the feature list to describe the relevant attribute characteristics of fault information processing.

[0099] This embodiment, through the above scheme, obtains the attributes of each characteristic object in the characteristic list, creates several instances based on the attributes, determines structure variables based on the instances, and unifies the format of the attribute characteristics of each characteristic object in the current vehicle based on the structure variables, generating the structure of each characteristic object. This can more intuitively reflect the fault status of the current product, reduce the processing difficulty of vehicle fault information processing methods, better process fault information according to the design object, and improve the speed and efficiency of vehicle fault information processing.

[0100] Furthermore, Figure 6 This is a flowchart illustrating the fifth embodiment of the vehicle fault information processing method of the present invention, as shown below. Figure 6 As shown, based on the first embodiment, a fifth embodiment of the vehicle fault information processing method of the present invention is proposed. In this embodiment, step S30 specifically includes the following steps:

[0101] Step S31: Obtain an initial list of faults related to the ECU from the structure.

[0102] It should be noted that an initial list of faults related to the ECU is obtained from the structure.

[0103] Step S32: Obtain changes in vehicle demand, and add, delete, or modify the initial fault list based on the changes in vehicle demand to obtain a fault list.

[0104] It is understandable that the changes in vehicle demand are obtained, and the initial fault list is added to, deleted from, or modified based on these changes to obtain a fault list.

[0105] Step S33: Process the fault of the current vehicle according to the fault list.

[0106] It should be understood that, based on the structural design, a corresponding fault list can be compiled, and the relevant fault information can be listed in the list according to the vehicle's requirements and other parameters.

[0107] Furthermore, step S33 includes the following steps:

[0108] The fault details in the fault list are read through the Unified Diagnostic Service (UDS).

[0109] The system searches for a processing strategy corresponding to the fault details in a preset fault handling strategy library, and handles the fault of the current vehicle according to the processing strategy.

[0110] In a specific implementation, Unified Diagnostic Services (UDS) can be supported to read the fault details from the fault list, search for the corresponding processing strategy from a pre-set fault handling strategy library, and handle the fault of the current vehicle according to the processing strategy.

[0111] Furthermore, the step of reading the fault details from the fault list through the Unified Diagnostic Service (UDS) includes the following steps:

[0112] The fault list is read using the fault handling function in the Unified Diagnostic Service (UDS) to obtain fault details.

[0113] In the specific implementation, it supports the reading and clearing of Diagnostic Trouble Code (DTC) information by the UDS service; after the power is turned off, the fault information is stored in the address of the Electrically Erasable Programmable Read Only Memory (EEPROM); for fault information that needs to be displayed on instrument panels and other display devices, as well as whether the fault information is valid, related fault handling functions are designed to read and write parameters in the fault list, so as to meet the requirements of the whole vehicle to obtain fault information through UDS, display prompt information through the instrument panel, and related changes in requirements.

[0114] This embodiment, through the above-described scheme, obtains an initial fault list related to the ECU from the structure; acquires changes in vehicle requirements; adds to, deletes, and modifies the initial fault list according to the changes in vehicle requirements to obtain a fault list; and processes the faults of the current vehicle according to the fault list. This approach can more intuitively reflect the fault status of the current product, reduce the processing difficulty of vehicle fault information processing methods, better process fault information according to the design object, solve the problems of poor software reusability and scalability, simplify method code maintenance, and improve the speed and efficiency of vehicle fault information processing.
