[0043] 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.

[0044] The original intention of the present invention is to realize user self-check and fault monitoring and early warning. Vehicle faults usually refer to abnormalities, noises, malfunctions, flameouts, etc. during driving. These faults may involve various aspects such as the engine, transmission, brake system, steering system, air conditioning system, tires, etc.

[0045] Figure 1 This is a flowchart of a fault information display method according to an embodiment of the present application.

[0046] like Figure 1 As shown, the fault information display method provided in this embodiment is applied to the electronic equipment of the vehicle, and is used to intuitively display the fault information to the user. The electronic equipment can be understood as the vehicle computer configured on the vehicle, and the so-called vehicle computer refers to a computer or embedded device that can provide multimedia services, information services and other functions to the user. The fault information display method includes the following steps:

[0047] S1. Obtain multiple diagnostic trouble codes from multiple ECUs.

[0048] The electronic device 100 is provided with a plurality of ports, each of which is connected to an ECU 200 for controlling a certain system of the vehicle, such as Figure 2As shown. Each ECU in the vehicle will periodically send the diagnostic trouble code it generates to the communication bus, such as the CAN bus. The ECU will send a message to the CAN bus once at a certain period, such as 100ms. The electronic device will receive the message in the bus based on each port and obtain multiple diagnostic trouble codes through parsing.

[0049] In the present application, diagnostic trouble codes are received based on a preset number. For example, the present application can set the number of diagnostic trouble codes sent by the system in real time to 256. However, in actual applications, vehicle systems usually do not process such a large number of DTCs at the same time. This redundant design helps to ensure that the system can operate stably when faced with a large number of DTCs, avoiding errors or abnormal situations. In addition, through the redundant design, the system is more flexible and scalable when processing DTCs, and can be adjusted and expanded according to the actual needs of the vehicle system. Therefore, this design can improve the performance and reliability of the system and provide better safety and stability for the vehicle.

[0050] S2. Save the diagnostic trouble codes in list format.

[0051] After obtaining multiple diagnostic trouble codes based on the messages sent by each ECU, these diagnostic trouble codes are saved in a list manner, that is, multiple diagnostic trouble codes are saved as a list. The specific method may include the following contents:

[0052] On the one hand, when a plurality of diagnostic trouble codes are initially obtained, that is, when the content in the list is empty, the plurality of diagnostic trouble codes are written into the list.

[0053] On the other hand, in order to ensure the validity of the diagnostic trouble codes in the list, they need to be updated, that is, the existing diagnostic trouble codes are updated according to the diagnostic trouble codes obtained subsequently, or the diagnostic trouble codes corresponding to the faults that have been repaired are deleted.

[0054] S3. Analyze the diagnostic fault code to obtain fault information.

[0055] That is, the diagnostic trouble codes are parsed according to the ODX parsing tool to obtain multiple fault information corresponding to all diagnostic trouble codes. The ODX parsing tool is a tool for parsing diagnostic trouble codes based on ODX files. ODX (Open Diagnosticdata eXchange) is a data exchange format that is used to standardize vehicle diagnostic data so that different diagnostic tools and systems can read and interpret data from the vehicle. The ODX file contains the data structure and protocol of the vehicle diagnostic information, so that the diagnostic software can correctly parse and display DTC and related data.

[0056] S4. Display fault information to the user.

[0057] After obtaining the fault information corresponding to the above diagnostic fault code, the above fault information is displayed in different display modes using the display interface of the electronic device so that the user can obtain the fault information in real time. The specific mode is as follows:

[0058] One way is that when the system finds one or more fault information, the fault information is displayed in real time through the display interface, that is, the fault information is displayed through a pop-up window or in a preset position.

[0059] Another way is to not display the fault information at all times, but to display it according to the user's operation. For example, when the user inputs an information display request by clicking, dragging, or inputting a voice control command, one or more fault information is displayed through the above display interface. This way can avoid interference with the current display content on the real interface, and it is only displayed when the user needs it.

[0060] It can be seen from the above technical solution that this embodiment provides a method for displaying fault information, which is applied to the electronic equipment of the vehicle, and the electronic equipment is equipped with multiple ports, each port is used to connect to an ECU of the vehicle. The method for displaying fault information specifically obtains multiple diagnostic fault codes from multiple ECUs; saves multiple diagnostic fault codes as a list, and the list saves valid diagnostic fault codes; parses and processes each diagnostic fault code in the list to obtain multiple fault information; and displays the fault information to the user. Through this solution, ordinary users can timely discover vehicle faults based on the fault information displayed by the vehicle electronic equipment without relying on the conversion reading device, and take disposal measures or further repairs in time on this basis, thereby ensuring driving safety.

[0066] like Figure 3 As shown, the fault information display method provided in this embodiment is applied to the electronic equipment of the vehicle, and is used to intuitively display the fault information to the user.

The fault information display device includes a data acquisition module 10, a fault code storage module 20, a fault analysis module 30 and a reality execution module 40.

[0067] The data acquisition module is used to obtain multiple diagnostic trouble codes from multiple ECUs.

[0068] The above electronic device is provided with multiple ports, each of which is connected to an ECU for controlling a certain system of the vehicle, such as Figure 2 As shown. Each ECU in the vehicle will periodically send the diagnostic trouble code it generates to the communication bus, such as the CAN bus. The ECU will send a message to the CAN bus once at a certain period, such as 100ms. The electronic device will receive the message in the bus based on each port and obtain multiple diagnostic trouble codes through parsing.

[0069] In the present application, diagnostic trouble codes are received based on a preset number. For example, the present application can set the number of diagnostic trouble codes sent by the system in real time to 256. However, in actual applications, vehicle systems usually do not process such a large number of DTCs at the same time. This redundant design helps to ensure that the system can operate stably when faced with a large number of DTCs, avoiding errors or abnormal situations. In addition, through the redundant design, the system is more flexible and scalable when processing DTCs, and can be adjusted and expanded according to the actual needs of the vehicle system. Therefore, this design can improve the performance and reliability of the system and provide better safety and stability for the vehicle.

[0070] In this application, the message is sent using the following message sending table:

[0071]

[0072] The fault code storage module is used to store diagnostic fault codes in a list format.

[0073] After obtaining multiple diagnostic trouble codes based on the messages sent by each ECU, these diagnostic trouble codes are saved in a list, that is, multiple diagnostic trouble codes are saved as a list. This module includes a saving processing unit 21 and an updating processing unit 22, such as Figure 4 shown.

[0074] The storage processing unit is used for writing the multiple diagnostic trouble codes into the list when multiple diagnostic trouble codes are initially obtained, that is, when the content in the list is empty.

[0075] In order to ensure the validity of the diagnostic trouble codes in the list, they need to be updated. The update processing unit is used to update the existing diagnostic trouble codes according to the diagnostic trouble codes obtained subsequently, or to delete the diagnostic trouble codes corresponding to the faults that have been repaired.

[0076] The fault analysis module is used to analyze the diagnostic fault code and obtain fault information.

[0077] That is, the diagnostic trouble codes are parsed according to the ODX parsing tool to obtain multiple fault information corresponding to all diagnostic trouble codes. The ODX parsing tool is a tool for parsing diagnostic trouble codes based on ODX files. ODX (Open Diagnosticdata eXchange) is a data exchange format that is used to standardize vehicle diagnostic data so that different diagnostic tools and systems can read and interpret data from the vehicle. The ODX file contains the data structure and protocol of the vehicle diagnostic information, so that the diagnostic software can correctly parse and display DTC and related data.

[0078] The display execution module is used to display fault information to the user.

[0079] After obtaining the fault information corresponding to the above diagnostic fault code, the above fault information is displayed in different display modes using the display interface of the electronic device so that the user can obtain the fault information in real time. The module includes a first display unit 41 and a second display unit 42. Figure 5 shown.

[0080] The first display unit is used to display the fault information in real time through the display interface when the system finds that one or more fault information appear, that is, to display the fault information through a pop-up window or at a preset position.

[0081] The second display unit is used to display according to the user's operation. For example, when the user inputs an information display request by clicking, dragging or inputting a voice control command, one or more fault information is displayed through the above display interface. In this way, it can avoid interfering with the current display content on the real interface, and it is only displayed when the user needs it.

[0082] It can be seen from the above technical scheme that this embodiment provides a fault information display device, which is applied to the electronic equipment of the vehicle, and the electronic equipment is equipped with multiple ports, each port is used to connect to an ECU of the vehicle. The fault information display device specifically obtains multiple diagnostic fault codes from multiple ECUs; saves multiple diagnostic fault codes as a list, and the list saves valid diagnostic fault codes; parses and processes each diagnostic fault code in the list to obtain multiple fault information; and displays the fault information to the user.
