[0024] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.

[0025] Ordinary users generally cannot read the corresponding fault information in real time. Only professional repair personnel can read the fault information through a dedicated port on the vehicle using specialized tools. As a result, ordinary users cannot detect vehicle faults in a timely manner, which in turn makes it impossible to ensure timely repairs and thus compromises driving safety.

[0026] The purpose of this disclosure is to enable user self-checking and fault monitoring and early warning. Vehicle faults typically refer to abnormalities, noises, malfunctions, or stalling that occur during vehicle operation. These faults may involve various aspects such as the engine, transmission, braking system, steering system, air conditioning system, and tires.

[0027] Figure 1 is a flowchart of a fault information display method according to an embodiment of this disclosure.

[0028] As shown in Figure 1, the fault information display method provided in this embodiment is applied to the electronic equipment of a vehicle to intuitively display fault information to the user. This electronic equipment can be understood as a vehicle infotainment system (VIS) installed in the vehicle. A VIS refers to a computer or embedded device capable of providing multimedia services, information services, and other functions to the user. The fault information display method includes the following steps S1 to S4.

[0029] S1. Obtain multiple diagnostic fault codes (DTCs) from multiple ECUs.

[0030] The aforementioned electronic device 100 has multiple ports, each connected to an ECU 200 for controlling a specific system of the vehicle, as shown in Figure 2. Each ECU in the vehicle periodically sends its generated diagnostic fault codes to a communication bus, such as the CAN bus. In one example, the ECU sends a message to the CAN bus at a certain period (e.g., 100ms). The electronic device then receives the messages from the bus at each port and parses them to obtain multiple diagnostic fault codes.

[0031] In this disclosure, diagnostic fault codes (DTCs) are received based on a preset number; for example, the system may be configured to send 256 DTCs in real time. However, in practical applications, vehicle systems typically do not process such a large number of DTCs simultaneously. This redundancy design helps ensure stable system operation when faced with a large number of DTCs, preventing errors or anomalies. Furthermore, through redundancy, the system is more flexible and scalable in handling DTCs, and can be adjusted and expanded according to the actual needs of the vehicle system. Therefore, this design can improve system performance and reliability, providing better safety and stability for the vehicle.

[0032] S2. Save multiple diagnostic fault codes to a list.

[0033] After obtaining multiple diagnostic fault codes based on the messages sent by each ECU, these diagnostic fault codes are saved in a list format. Specifically, the list may contain the following:

[0034] On the one hand, when multiple diagnostic fault codes are initially obtained, i.e., the list is empty, multiple diagnostic fault codes are written into the list.

[0035] On the other hand, in order to ensure the validity of the diagnostic fault codes in the list, they need to be updated. That is, the existing diagnostic fault codes are updated based on the diagnostic fault codes obtained later, or the diagnostic fault codes corresponding to the faults that have been repaired are deleted.

[0036] S3. Analyze and process multiple diagnostic fault codes to obtain multiple fault messages.

[0037] The ODX parsing tool analyzes the diagnostic fault codes to obtain multiple fault messages corresponding to each code. The ODX parsing tool is a tool for parsing diagnostic fault codes based on ODX files. ODX (Open Diagnostic Data Exchange) is a data exchange format used to standardize vehicle diagnostic data, enabling different diagnostic tools and systems to read and interpret data from the vehicle. ODX files contain the data structure and protocols for vehicle diagnostic information, allowing diagnostic software to correctly parse and display DTCs and related data.

[0038] S4. Display multiple fault messages to the user.

[0039] After obtaining the fault information corresponding to the aforementioned diagnostic fault codes, the electronic device's display interface is used to display this fault information in different ways, so that the user can receive the fault information in real time. The specific methods are as follows:

[0040] One approach is to display one or more fault messages in real time through the display interface when the system detects them. For example, the fault messages can be displayed via a pop-up window or in a preset location.

[0041] Another approach is to not display fault information constantly, but rather based on user actions. For example, when a user requests information display by clicking, dragging, or entering voice control commands, one or more fault messages are displayed on the aforementioned interface. This method avoids interfering with the currently displayed content, only showing it when needed by the user.

[0042] As can be seen from the above technical solution, this embodiment provides a fault information display method. This method is applied to the electronic equipment of a vehicle, which is configured with multiple ports, each port being connected to each ECU of the vehicle. In this fault information display method, multiple diagnostic fault codes are obtained from multiple ECUs; these multiple diagnostic fault codes are saved to a list, which stores valid diagnostic fault codes; each diagnostic fault code in the list is parsed to obtain multiple fault information entries; and these multiple fault information entries are displayed to the user. Through this solution, ordinary users can promptly detect vehicle faults based on the fault information displayed by the vehicle's electronic equipment without relying on dedicated reading equipment, and take timely measures or further repairs accordingly, thereby ensuring driving safety.

[0043] The flowcharts and block diagrams in the accompanying drawings illustrate the architecture, functionality, and operation of possible implementations of systems, methods, and computer program products according to various embodiments of the present disclosure. In this regard, each block in a flowchart or block diagram may represent a module, segment, or portion of code containing one or more executable instructions for implementing a specified logical function. It should also be noted that in some alternative implementations, the functions indicated in the blocks may occur in a different order than those indicated in the drawings. For example, two consecutively indicated blocks may actually be executed substantially in parallel, and they may sometimes be executed in reverse order, depending on the functions involved. It should also be noted that each block in a block diagram and / or flowchart, and combinations of blocks in block diagrams and / or flowcharts, may be implemented using a dedicated hardware-based system that performs the specified function or operation, or using a combination of dedicated hardware and computer instructions.

[0044] Although the operations are described in a specific order, this should not be construed as requiring these operations to be performed in the specific order shown or in a sequential order. In certain environments, multitasking and parallel processing may be advantageous.

[0045] It should be understood that the steps described in the method embodiments of this disclosure may be performed in different orders and / or in parallel. Furthermore, the method embodiments may include additional steps and / or omit the steps shown. The scope of this disclosure is not limited in this respect.

[0046] Computer program code for performing the operations of this disclosure can be written in one or more programming languages ​​or a combination thereof, including but not limited to object-oriented programming languages ​​such as Java, Smalltalk, and C++, as well as conventional procedural programming languages ​​such as C or similar languages. The program code can be executed entirely on the user's computer, partially on the user's computer, as a standalone software package, partially on the user's computer and partially on a remote computer, or entirely on a remote computer or server. In cases involving remote computers, the remote computer can be connected to the user's computer via any type of network—including a local area network (LAN) or a wide area network (WAN)—or can be connected to an external computer.

[0047] Figure 3 is a block diagram of a fault information display device according to an embodiment of the present disclosure.

[0048] As shown in Figure 3, the fault information display method provided in this embodiment is applied to the electronic equipment of a vehicle to intuitively display fault information to the user. This electronic equipment can be understood as a vehicle infotainment system (VIS) installed in the vehicle. A VIS refers to a computer or embedded device capable of providing multimedia services, information services, and other functions 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 display execution module 40.

[0049] The data acquisition module is used to acquire multiple diagnostic fault codes from multiple ECUs.

[0050] The aforementioned electronic equipment has multiple ports, each connected to an ECU (Electronic Control Unit) for controlling a specific system in the vehicle, as shown in Figure 2. Each ECU in the vehicle periodically sends its generated diagnostic fault codes to a communication bus, such as the CAN bus. In one example, the ECU sends a message to the CAN bus at a certain interval (e.g., 100ms). The electronic equipment then receives the messages from the bus at each port and parses them to obtain multiple diagnostic fault codes.

[0051] In this disclosure, diagnostic fault codes (DTCs) are received based on a preset number; for example, the system may be configured to send 256 DTCs in real time. However, in practical applications, vehicle systems typically do not process such a large number of DTCs simultaneously. This redundancy design helps ensure stable system operation when faced with a large number of DTCs, preventing errors or anomalies. Furthermore, through redundancy, the system is more flexible and scalable in handling DTCs, and can be adjusted and expanded according to the actual needs of the vehicle system. Therefore, this design can improve system performance and reliability, providing better safety and stability for the vehicle.

[0052] In this disclosure, messages are sent using the following message sending table:

[0053] The fault code storage module is used to store diagnostic fault codes in a list format.

[0054] After obtaining multiple diagnostic fault codes based on the messages sent by each ECU, these diagnostic fault codes are saved in a list format, that is, multiple diagnostic fault codes are saved as a list. This module includes a storage processing unit 21 and an update processing unit 22, as shown in Figure 4.

[0055] The storage processing unit is used to write multiple diagnostic fault codes into the list when multiple diagnostic fault codes are initially obtained, i.e., the list is empty.

[0056] To ensure the validity of the diagnostic fault codes in the list, they need to be updated. The update processing unit is used to update the existing diagnostic fault codes based on the diagnostic fault codes obtained subsequently, or to delete the diagnostic fault codes corresponding to faults that have been repaired.

[0057] The fault analysis module is used to parse and process multiple diagnostic fault codes to obtain multiple fault messages.

[0058] The ODX parsing tool analyzes the diagnostic fault codes to obtain multiple fault messages corresponding to each code. The ODX parsing tool is a tool for parsing diagnostic fault codes based on ODX files. ODX is a data exchange format used to standardize vehicle diagnostic data, enabling different diagnostic tools and systems to read and interpret data from the vehicle. ODX files contain the data structure and protocols of vehicle diagnostic information, allowing diagnostic software to correctly parse and display DTCs and related data.

[0059] The display execution module is used to show multiple fault messages to the user.

[0060] After obtaining the fault information corresponding to the aforementioned diagnostic fault codes, the electronic device displays the fault information in different display modes through its display interface, so that the user can obtain the fault information in real time. This module includes a first display unit 41 and a second display unit 42, as shown in Figure 5.

[0061] The first display unit is used to display one or more fault messages in real time through the display interface when the system detects them. For example, the fault messages can be displayed via a pop-up window or in a preset location.

[0062] The second display unit is used to display information based on user actions. For example, when a user requests information display by clicking, dragging, or inputting voice control commands, one or more fault messages are displayed on the aforementioned display interface. This method avoids interfering with the currently displayed content on the physical interface, only displaying information when needed by the user.

[0063] As can be seen from the above technical solution, this embodiment provides a fault information display device. This device is applied to the electronic equipment of a vehicle, which is equipped with multiple ports, each port being connected to each ECU of the vehicle. Specifically, the fault information display device acquires multiple diagnostic fault codes from multiple ECUs; saves the multiple diagnostic fault codes into a list, which stores valid diagnostic fault codes; parses and processes each diagnostic fault code in the list to obtain multiple fault information entries; and displays the multiple fault information entries to the user. Through this solution, ordinary users can promptly detect vehicle faults based on the fault information displayed by the vehicle's electronic equipment without relying on dedicated reading equipment, and take timely measures or further repairs accordingly, thereby ensuring driving safety.

[0064] The units described in the embodiments of this disclosure can be implemented in software or in hardware. The name of a unit does not necessarily limit the unit itself; for example, the first acquisition unit can also be described as "a unit that acquires at least two Internet Protocol addresses".

[0065] The functions described above in this document can be performed, at least in part, by one or more hardware logic components. For example, exemplary types of hardware logic components that can be used, without limitation, include: Field Programmable Gate Arrays (FPGAs), Application-Specific Integrated Circuits (ASICs), Application Standard Products (ASSPs), System-on-Chip (SoCs), Complex Programmable Logic Devices (CPLDs), and so on.
