Detailed Description
The technical solutions in the embodiments of the present invention will be described below with reference to the drawings in the embodiments of the present invention.
Referring to fig. 1, fig. 1 is a flowchart illustrating a method for visualizing a vehicle diagnostic device according to an embodiment of the present invention, where the method can be applied to the vehicle diagnostic device 100 in fig. 2, and the vehicle diagnostic device 100 and a vehicle 200 establish a communication connection. Specifically, the vehicle diagnosis device 100 may be a dedicated instrument for diagnosing a vehicle fault, or may be an electronic device, such as a mobile phone or a tablet computer, which is equipped with vehicle diagnosis software and can implement a diagnosis function. As shown in fig. 1, the vehicle failure information display method may include the following steps 110 to 150.
In step 110, vehicle information is obtained.
Specifically, the vehicle information includes vehicle type information, and the vehicle diagnosis device may obtain the vehicle type information of the vehicle according to a vehicle identification VIN code of the vehicle by obtaining the VIN code.
And step 120, determining the Electronic Control Unit (ECU) system configuration information of the vehicle to be diagnosed according to the vehicle information.
In one embodiment, the vehicle information includes vehicle type information, and the determining the electronic control unit ECU system configuration information of the vehicle to be diagnosed according to the vehicle information specifically includes the following steps:
and determining the ECU system configuration information of the vehicle to be diagnosed according to the vehicle type information.
Specifically, the vehicle type information of the vehicle and the ECU system configuration information of the vehicle are corresponding, and thus the ECU system configuration information of the vehicle can be acquired according to the vehicle type information. The ECU system configuration information may include an ECU name and a name of a branch line to which the ECU belongs, where the branch line to which the ECU belongs is used to represent a communication bus by which the ECU communicates with an associated ECU.
And step 130, drawing a topological graph of the vehicle to be diagnosed according to the ECU system configuration information and presenting the topological graph to a user.
In one embodiment, the ECU system configuration information includes a branch name to which each ECU belongs, and the step of drawing the topological graph of the vehicle to be diagnosed according to the ECU system configuration information may specifically include the following steps:
drawing ECUs with the same name of the branch lines on the same branch line of the vehicle topological graph;
and connecting all branch lines of the vehicle topological graph to generate a complete topological graph of the vehicle to be diagnosed.
Specifically, branch lines in a vehicle topological graph corresponding to each ECU can be determined according to the name of the branch line to which the ECU belongs, the ECUs with the same name of the branch lines to which the ECU belongs are drawn on the same branch line of the vehicle topological graph, all the branch lines are connected to obtain a complete topological graph, and the complete topological graph is presented to a user, so that the combination mode of the ECUs of the vehicle can be visually embodied, and the communication connection mode and the working state among different ECUs can be visually displayed. In addition, the ECU system configuration information may further include root node information indicating whether an ECU is a root node, and if an ECU is a root node, the ECU may be drawn on a main line of the vehicle topology map, and a complete topology map may be obtained after the main line is connected to all branch lines. The ECU located on the main line and the other ECUs located on the branch lines communicate via a communication bus represented by the main line.
And step 140, determining a target ECU to be diagnosed according to the operation instruction of the topological graph by the user.
In one embodiment, the determining a target ECU to be diagnosed according to an operation instruction of a user on the topological graph specifically includes the following steps:
acquiring a target diagnosis mode selected by a user;
and determining a target ECU to be diagnosed according to the target diagnosis mode.
Specifically, each ECU on the topological graph may correspond to one ECU selection control, and if an operation instruction of a user for one or more ECU selection controls among all the ECU selection controls is received, it is determined that the obtained target diagnosis mode is the selection detection mode, and the vehicle diagnosis device determines the ECU corresponding to the one or more ECU selection controls as the target ECU to be diagnosed, so as to diagnose the target ECU. It can be understood that the user may select a single ECU on a certain branch line, or select all ECUs on a certain branch line, or select ECUs on all branch lines, or the like, so that the vehicle diagnosis apparatus determines it as the target ECU to be diagnosed.
Optionally, a detection control for indicating different diagnosis modes may be further included on the display interface displaying the topological diagram. Illustratively, a selection detection control may be included for triggering a selection detection mode. If the user operation aiming at the selection detection control is received, the target diagnosis mode is determined to be the selection detection mode, the operation instruction of the user aiming at the specific ECU selection control in the ECU topological graph is obtained, and the ECU corresponding to the selected specific ECU selection control is determined to be the target ECU to be detected, so that the specific ECU is detected. It can be understood that the user can choose to test a single ECU, the ECUs of the same branch line or all the ECUs according to actual requirements. By displaying the ECU topology including the ECU selection control on the display interface of the vehicle diagnosis apparatus 100, the ECUs that can be detected can be displayed more intuitively, the user operation is more convenient than the display manner of the menu list, and various selection detection manners are provided, and the operation time of the user can be saved while the selection detection function is confirmed.
Illustratively, the display interface displaying the topological graph may further include an intelligent detection control, where the intelligent detection control is used to trigger an intelligent detection mode and select an ECU meeting a preset condition for detection. The preset condition may be adjusted according to actual requirements, for example, only the ECU with a failure in the history of the vehicle may be selected, or the ECU with a high possibility of failure may be selected, or all the ECUs may be selected by default for detection, and the like, which is not limited in the present application. And if the user operation aiming at the intelligent detection control is received, determining that the target diagnosis mode is the intelligent detection mode, and determining the ECU meeting the preset conditions as the target ECU to be diagnosed to detect the target ECU.
For example, a system scanning control may be further included on the display interface displaying the topological diagram, where the system scanning control is configured to trigger a system scanning mode to scan all ECUs of the vehicle, and the purpose of the scanning is to detect whether the ECU is configured, that is, whether the ECU can normally communicate with the vehicle diagnostic device. Then, if the user operation for the system scanning control is received, the target diagnosis mode is determined to be the system scanning mode, and all the ECUs of the vehicle are scanned. By displaying the different detection controls on the display interface of the vehicle diagnosis device 100 displaying the topological graph, multiple detection modes can be provided for a user, the user can conveniently select the detection modes according to needs, the visualization degree of the diagnosis interface of the vehicle diagnosis device is improved, and the user experience is improved.
And 150, diagnosing the target ECU to be diagnosed to obtain a diagnosis result and presenting the diagnosis result to a user.
In one embodiment, the method further comprises the steps of:
acquiring the diagnosis state of an ECU of the vehicle to be diagnosed;
and marking the vehicle ECU on the topological graph according to the mapping relation between the preset diagnosis state and the mark.
Specifically, in the process of diagnosing the target ECU to be diagnosed, the diagnostic state of the ECU of the vehicle to be diagnosed may be obtained, and the ECU may be marked in a corresponding marking form according to the diagnostic state and a preset mapping relationship, and displayed in the topological graph. For example, the diagnostic status of the ECU may include: detected completed and fault code present, detected completed and fault code absent, detected, not detected, unconfigured, etc. Accordingly, the diagnostic states may each correspond to a different marker format. For example, the ECU whose detection is completed and the fault code exists may be identified in red, and in addition, the number of faults existing in the ECU may be displayed in numbers, while the ECU whose detection is completed and the fault code does not exist may be identified in green, the ECU whose detection is in progress may be identified in yellow, the ECU whose detection is not in progress may be identified in white, the ECU whose configuration is not in progress may be identified in gray, and so on, which is not limited in the present application.
After the detection of all the target ECUs to be diagnosed is completed, a diagnosis result can be obtained, and the diagnosis result is presented to a user, specifically, the diagnosis result can comprise an ECU graphical control corresponding to the ECU with the fault code, and the ECU graphical control and general ECU icons corresponding to other ECUs are displayed on a user interface of the vehicle diagnosis equipment in a topological graph mode, so that the user can conveniently know the whole fault condition of the ECU system of the vehicle. For example, if there are 2 red ECU graphical controls in the topology map of the user interface, the user may be notified that the vehicle has a fault associated with this 2 ECUs, independent of the other ECUs, thereby defining the range in which the fault may exist. Further, the ECU graphical control may be configured to trigger display of fault code information of the ECU, where the fault code information is used to describe a component having a fault and a fault cause of the component having the fault, among vehicle components controlled by the ECU, and thus the fault code information may include information such as a fault code, a fault description (i.e., a faulty component and a fault cause), so as to provide more specific fault information for a user.
Thus, in one embodiment, the method may further comprise the steps of:
acquiring a fault code information checking instruction of a user;
and displaying the fault code information according to the fault code information viewing instruction.
Specifically, a fault code information checking instruction of a user is obtained, that is, a user operation instruction of the user for the ECU graphical control is obtained, and according to the fault code information checking instruction, the vehicle-mounted diagnostic device displays the fault code information of the ECU. If a plurality of fault codes exist in the ECU, a plurality of pieces of fault code information corresponding to the ECU may be displayed, and each piece of fault code information may include a fault code, a fault description, that is, a faulty component and a fault cause), and the like. Therefore, the specific fault information of the ECU can be visually displayed, and a user can conveniently find the specific fault position of the vehicle to be diagnosed according to the information.
In one embodiment, the method further comprises the steps of:
displaying a data stream viewing control on a display interface for displaying the fault code information;
acquiring a data stream viewing instruction of a user for the data stream viewing control;
and displaying the data stream associated with the fault code information according to the data stream viewing instruction.
Specifically, a data stream viewing control is displayed on a display interface for displaying the fault code information, and the data stream viewing control is used for triggering and displaying the data stream associated with the fault code information. And then acquiring a data stream viewing instruction of a user, and responding to the instruction to display the data stream related to the fault code information. In this way, the display of the fault code associated with the data stream is achieved. In the prior art, after the fault code is acquired, the user interface of the vehicle diagnostic equipment needs to be manually operated, the ECU menu option related to the fault code is found from the plurality of ECU menu options, and the corresponding data stream is acquired after selection. Therefore, compared with the prior art, the method and the device can be used for displaying the fault codes and the data streams in a correlation mode, a user can conveniently and quickly find the data streams related to the fault codes, and the diagnosis efficiency is improved.
It can be understood that if a plurality of fault codes exist in the ECU, a plurality of data stream viewing controls can be displayed while a plurality of pieces of fault code information corresponding to the ECU are displayed, each data stream viewing control corresponds to one piece of fault code information, so that a user can conveniently obtain a data stream associated with certain fault code information, abnormal signal data can be found, and a specific fault reason can be found.
And the display interface of the data stream can display a part of the data stream associated with the fault code information, wherein the part of the data stream is determined according to preset configuration information. In this case, the display interface may include an addition control, and the addition control is configured to configure the other data stream associated with the fault code information to be displayed on the data stream display interface, that is, if a user operation instruction for the addition control is received, the vehicle diagnostic device adds the other data stream associated with the fault code information to the data stream display interface, or replaces the existing data stream, and the like. In addition, the display interface of the data stream may also display all data streams associated with the fault code information.
Optionally, the vehicle diagnosis apparatus may provide a fault analysis function, the fault analysis function including: and comparing the abnormal data flow with the normal data flow, explaining the abnormal data flow, and analyzing the potential influence of the fault, such as the influence on driving safety and the like. And if a fault analysis instruction of a user is received, the vehicle diagnosis equipment performs fault analysis and displays a fault analysis result.
Optionally, the user interface for displaying the diagnosis result may further include a report generation control, where the report generation control is configured to trigger generation of a detection report, the detection report includes fault code information of the ECU having the fault code and a data stream associated with the fault code information, and the detection report may further include the fault analysis result. Therefore, if an operation instruction of the user for the report generation control is received, a detection report is generated and stored.
Namely, the report generation control is displayed on the user interface for displaying the diagnosis result, so that a user can conveniently and quickly obtain the detection report to find and solve the fault. Of course, the report generation control may also be displayed on a data stream display interface, and the like, which is not limited in this application.
In the embodiment of the invention, after vehicle information is acquired, ECU system configuration information is determined, a topological graph of the vehicle to be diagnosed is drawn according to the ECU system configuration information, and the topological graph is presented to a user; and determining the target ECU to be diagnosed according to the operation instruction of the user, diagnosing the target ECU to be diagnosed to obtain a diagnosis result and presenting the diagnosis result to the user. The combination mode of the ECU of the vehicle is visually displayed in the form of a topological graph, so that the ECU can be conveniently operated by a user, a data stream viewing control piece associated with the fault code information is displayed on a user interface displaying the fault code information, the associated display of the fault code and the data stream is realized, the data stream can be conveniently and quickly acquired by the user, the visual diagnosis is also realized, and the vehicle fault can be conveniently and quickly diagnosed by the user. Therefore, the method and the device can simplify user operation and improve diagnosis efficiency.
The following describes a process for implementing the visual vehicle diagnosis method of the present application, which is executed by a vehicle diagnosis apparatus, in a specific application scenario with reference to fig. 3 to 7. The method may comprise the steps of:

specifically, ECU system configuration information of the vehicle is acquired, and the ECU system configuration information includes the ECU name and the branch line name to which the ECU belongs, then the branch line name to which each ECU of the vehicle belongs can be determined. If the names of the branch lines to which the plurality of ECUs belong are the same, the plurality of ECUs can be drawn on the same branch line of the vehicle topological graph, and then all the branch lines to which the ECUs of the vehicle belong are connected to obtain the complete topological graph of the vehicle. Thus, the map of the ECU topology of the vehicle is completed. For example, as shown in fig. 3, the ECU topology of the vehicle includes 3 branches: the system comprises an H-CAN branch Line, an MS-CAN branch Line and a K-Line branch Line, wherein each branch Line comprises a plurality of different ECUs. Through the ECU topological graph of the vehicle, the ECU included in the vehicle can be intuitively known, and different ECUs communicate with each other through the communication bus corresponding to the branch line.

for example, selection instructions for the ECU selection controls (i.e., the ECM selection control, the TCM selection control, and the ABS selection control) and the detection control (i.e., the selection detection control) in the user interface 301 are received, and the 3 ECUs of the ECM, the TCM, and the ABS are detected. When the detection process is performed, a user interface 302 may be displayed, where the graphic controls corresponding to the ECM, the TCM, and the ABS are respectively represented in different mark forms, and present diagnostic statuses of the 3 ECUs are shown, that is, the ECM has completed detection and has a fault code, the TCM has completed detection and has no fault code, and the ABS is still in detection.
(4) In response to the user operation on the ECU graphical control, displaying a user interface 303 (see fig. 5), which includes fault code information and data stream viewing controls of the ECU having the fault code;
for example, a selection instruction for an ECM graphical control in the user interface 302 is received, failure information related to the ECM is acquired, and the user interface 303 is displayed. Because 6 fault codes exist in the ECM through detection, the 6 fault codes are all displayed, and for each fault code, the associated fault code information and a data stream viewing control are displayed, wherein the fault code information can comprise the fault code, a fault component and a fault reason, and the data stream viewing control can trigger the display of the data stream associated with the fault code information.
(5) In response to user operation of the data flow view control, displaying a user interface 304 (see FIG. 6) including a data flow associated with fault code information for the ECU having the fault code;
for example, a selection instruction for the data stream viewing control associated with the 2 nd fault code (specifically, P164a00) in the user interface 303 is received, and the user interface 304 is displayed to show the data stream associated with the fault code information (i.e., oil pressure switch-unreliable signal), so that the user can find abnormal signal data and find a specific fault reason and position conveniently.
(6) In response to a user interface jump operation, displaying a user interface 305 (see FIG. 7) that includes a report generation control; and generating and saving the detection report in response to the user operation of the report generation control.
For example, an instruction of user interface jump or return is received, and a user interface 305 is displayed, which displays a detection result after the ECU detection is completed, so that a user can conveniently continue to check the ECU fault information or obtain a detection report. When a selection instruction for a report generation control in the user interface 305 is received, a detection report is generated and saved.
