[0049] It should be understood that the specific embodiments described herein are only used to explain the embodiments of the present application and are not used to limit the embodiments of the present application.

[0050] Reference Figure 1 , Figure 1 This is the diagnostic teaching system architecture used in the implementation of the diagnostic teaching method in the embodiment of this application.

[0051] The diagnostic teaching system includes a teaching-end device, a server, and a learning-end device. The teaching-end device is managed by a teacher and has built-in diagnostic software and teaching software, wherein the diagnostic software is used for the teacher's diagnostic operations, and the teaching software is used for the teacher to convert the diagnostic operations into teaching content. The server is used to store teaching content and learning permissions. The learning-end device is held by the student and is used to obtain learning content from the server for learning. The teaching-end device is communicatively connected to the server, and the learning-end device is communicatively connected to the server. The teaching-end device and the learning-end device can be computing devices with communication and interaction functions, such as mobile terminals, personal digital assistants, and personal computers. The server can be a workstation, a cluster server, or a distributed server, etc., which is not specifically limited here.

[0052] In some specific implementation scenarios, the teaching-end device configures diagnostic teaching content and learning permissions, and sends the diagnostic teaching content to the server; the learning-end device sends a learning request to the server; the server determines the learning permissions and the target diagnostic teaching content corresponding to the learning permissions based on the learning request; the learning-end device receives the target diagnostic teaching content sent by the server; the learning-end device performs diagnostic simulation learning based on the target diagnostic teaching content.

[0053] Based on the above multi-terminal system architecture, an embodiment of the diagnostic teaching method of the present application is proposed.

[0054] Reference Figure 2 , Figure 2 This is a flow chart of the first embodiment of the diagnostic teaching method of the present application. The method is applied to a diagnostic teaching system. The diagnostic teaching system includes a teaching end device, a learning end device and a server. The teaching end device is communicatively connected to the server, and the server is communicatively connected to the learning end device. The diagnostic teaching method includes:

[0055] Step S100: the teaching end device configures diagnostic teaching content and learning authority, and sends the diagnostic teaching content to the server.

[0056] In some specific embodiments, the diagnostic teaching content includes the operation process of vehicle fault diagnosis, the result of vehicle diagnosis, and the processing method for the vehicle diagnosis result. Considering that each student has different understanding of the teaching content, the learning authority of each student terminal can be set in a targeted manner to achieve teaching in accordance with their aptitude.

[0057] In some specific implementation scenarios, teachers can configure the learning rights and corresponding diagnostic teaching content of each learning end user through the teaching end device. Specifically, the learning rights include the vehicle models that the learning end device can perform simulated diagnostic learning and the electronic control system ECU for simulated diagnosis. For example, learning end device 1 can simulate the engine system ECU diagnosis and transmission system ECU diagnosis of Volkswagen models, the engine system ECU diagnosis and body control system ECU diagnosis of BMW models, and learning end device 2 can simulate the engine system ECU diagnosis and brake system ECU diagnosis of Toyota models, the engine system ECU diagnosis and transmission system ECU diagnosis of Honda models, etc. The diagnostic teaching content includes the diagnostic operation process of the electronic control system ECU of each vehicle model, the diagnostic results, and the processing methods for the diagnostic results. After the teaching end device is configured with learning rights and diagnostic teaching content, it is uploaded to the server.

[0058] Step S200: the learning end device sends a learning request to the server.

[0059] In some specific embodiments, the learning request is generated based on the student's operation on the learning end device. For example, the student can select a specific vehicle model and the corresponding ECU in the learning end device and then generate a learning request, which includes the vehicle model information and ECU information. Of course, in some other implementation scenarios, when the user needs to learn specific maintenance operation instructions, the learning request can also include vehicle fault information, fault system information, etc. The learning request carries the learning end device identifier. When the student submits a learning request to start learning, the learning request is sent to the server so that the server provides corresponding diagnostic teaching content based on the learning request.

[0060] Step S300: The server determines corresponding learning authority and target diagnosis teaching content according to the learning request.

[0061] In some specific embodiments, after receiving a learning request, the server first determines the learning authority corresponding to the learning request based on the learning end device identifier in the learning request. For example, when the learning end device identifier included in the learning request is learning end device 1, the corresponding learning authority includes: the vehicle models and ECUs that can be learned by the learning end device 1 include the engine system ECU and transmission system ECU of Volkswagen models, and the engine system ECU and body control system ECU of BMW models; when the learning end device identifier included in the learning request is learning end device 2, the corresponding learning authority includes: the vehicle models and ECUs that can be learned by the learning end device 2 include the engine system ECU and brake system ECU of Toyota models, and the engine system ECU and transmission system ECU of Honda models.

[0062] After determining the corresponding learning authority, the server determines the corresponding target diagnosis teaching content according to the vehicle model and ECU in the learning request. Specifically, when the device identifier contained in the learning request is learning end device 1, the vehicle model is a BMW model, and the ECU is an engine ECU, then the target diagnosis teaching content corresponding to the learning request is the diagnostic process, fault information, fault repair and other teaching content of the BMW model engine system ECU. When the device identifier contained in the learning request is learning end device 1, the vehicle model is an Audi car, and the ECU is an engine ECU, since the vehicle model is not in the learning authority of the learning end device, there is no corresponding target diagnosis teaching content for the learning request. The server feeds back a prompt to the learning end device that it has no permission to operate, reminding the student to adjust the learning request.

[0063] Step S400: the learning end device receives the target diagnosis teaching content sent by the server.

[0064] In some specific embodiments, after determining the corresponding learning authority and target diagnosis teaching content according to the learning request, the server sends the target diagnosis teaching content to the learning end device. After receiving the target diagnosis teaching content, the learning end device starts the learning process.

[0065] Step S500: the learning end device performs diagnosis simulation learning according to the target diagnosis teaching content.

[0066] In some specific embodiments, the learning end device performs diagnostic simulation learning according to the obtained target diagnostic teaching content. Specifically, the learning end device simulates the diagnostic process of the corresponding ECU according to the ECU diagnostic process file in the target diagnostic teaching content, simulates the actual fault code according to the fault information, and simulates the repair steps and process according to the fault repair teaching content, so that the student users of the learning end device can better master the target diagnostic teaching content.

[0067] This embodiment configures the learning authority of the learning end device and the diagnostic teaching content corresponding to the learning authority on the teaching end device. The learning end device sends a learning request, the server determines the learning authority and target diagnostic teaching content corresponding to the learning request, the learning end device receives the corresponding learning authority and target diagnostic teaching content, and performs diagnostic simulation teaching. This reduces the teaching cost to a certain extent, allows students to view the target diagnostic teaching content corresponding to the user's learning request more directly, improves the efficiency of vehicle diagnostic teaching, and optimizes the learning effect of vehicle diagnostic teaching on the learning end device.

[0068] Furthermore, based on the first embodiment of the diagnostic teaching method of the embodiment of the present application, a second embodiment of the diagnostic teaching method of the embodiment of the present application is proposed.

[0069] The difference between the second embodiment of the diagnosis teaching method and the first embodiment of the diagnosis teaching method is that in this embodiment, the diagnosis teaching method is applied to the learning end device, referring to Figure 3 , the diagnostic teaching method includes:

[0070] Step A1, sending a learning request to the server.

[0071] In some specific embodiments, the learning request is generated based on the student's operation on the learning terminal device. For example, the student can select a specific vehicle model and the corresponding ECU in the learning terminal device, and generate a corresponding learning request based on the vehicle model and ECU selected above. The learning request includes the vehicle model information and ECU information. Of course, in some other implementation scenarios, when the user needs to learn specific maintenance operation instructions, the learning request may also include vehicle fault information, fault system information, etc. The learning request carries the learning terminal device identifier. When the student submits a learning request through the learning terminal device to start learning, the learning request is sent to the server through the learning terminal device.

[0072] Step A2, receiving the target diagnosis teaching content determined by the server according to the learning request, wherein the target diagnosis teaching content is determined by the server in the diagnosis teaching content according to the learning authority corresponding to the learning request, and the target diagnosis teaching content and learning authority are pre-configured by the teaching end device and stored in the server.

[0073] In the server, the learning authority corresponding to the learning request from the learning terminal device can be determined through the learning request, and then the target diagnostic teaching content of the server in the diagnostic teaching content can be determined according to the learning authority.

[0074] In some specific embodiments, the diagnostic teaching content includes the operation process of vehicle fault diagnosis, the result of vehicle diagnosis, and the processing method for the vehicle diagnosis result. Considering that each student has different understanding of the teaching content, the learning authority of each student terminal can be set in a targeted manner to achieve teaching in accordance with their aptitude.

[0075] In some specific implementation scenarios, teachers can configure the learning permissions and corresponding diagnostic teaching content of each learning user through the teaching-end device. Specifically, the learning permissions include the vehicle models for which the learning-end device can perform simulated diagnostic learning and the electronic control system ECU for simulated diagnosis. For example, learning-end device 1 can simulate the engine system ECU diagnosis and transmission system ECU diagnosis of Volkswagen models, the engine system ECU diagnosis and body control system ECU diagnosis of BMW models, and learning-end device 2 can simulate the engine system ECU diagnosis and brake system ECU diagnosis of Toyota models, the engine system ECU diagnosis and transmission system ECU diagnosis of Honda models, etc. The diagnostic teaching content includes the diagnostic operation process of the electronic control system ECU of each vehicle model, the diagnostic results, and the processing methods for the diagnostic results.

[0076] In some specific embodiments, after receiving a learning request, the server first determines the learning authority corresponding to the learning request based on the learning end device identifier in the learning request. For example, when the learning end device identifier included in the learning request is learning end device 1, the corresponding learning authority includes: the vehicle models and ECUs that can be learned by the learning end device 1, specifically including the engine system ECU and transmission system ECU of Volkswagen models, and the engine system ECU and body control system ECU of BMW models; when the learning end device identifier included in the learning request is learning end device 2, the corresponding learning authority includes: the vehicle models and ECUs that can be learned by the learning end device 2 include the engine system ECU and brake system ECU of Toyota models, and the engine system ECU and transmission system ECU of Honda models.

[0077] After determining the corresponding learning authority, the server determines the corresponding target diagnosis teaching content according to the vehicle model and ECU in the learning request. Specifically, when the device identifier contained in the learning request is learning end device 1, the vehicle model is a BMW model, and the ECU is an engine ECU, then the target diagnosis teaching content corresponding to the learning request is the diagnostic process, fault information, fault repair and other teaching content of the BMW model engine system ECU. When the device identifier contained in the learning request is learning end device 1, the vehicle model is an Audi car, and the ECU is an engine ECU, since the vehicle model is not in the learning authority of the learning end device, there is no corresponding target diagnosis teaching content for the learning request. The server feeds back a prompt to the learning end device that it has no permission to operate, reminding the student to adjust the learning request.

[0078] Step A3, performing diagnostic simulation learning according to the target diagnostic teaching content.

[0079] In some specific embodiments, the learning end device performs diagnostic simulation learning according to the obtained target diagnostic teaching content. Specifically, the learning end device simulates the diagnostic process of the corresponding ECU according to the ECU diagnostic process file in the target diagnostic teaching content, simulates the actual fault code according to the fault information, and simulates the repair steps and process according to the fault repair teaching content, so that the student users of the learning end device can better master the target diagnostic teaching content.

[0080] In this embodiment, the learning end device sends a learning request to the server, then receives the target diagnostic teaching content determined by the server based on the learning request, and then performs diagnostic simulation learning based on the target diagnostic teaching content. This not only meets the students' needs for personalized learning through the learning end device, but also reduces the cost of real-vehicle demonstrations for diagnostic teaching, meets students' real-time diagnostic simulation teaching needs, and improves teaching efficiency.

[0081] Furthermore, based on the first and second embodiments of the diagnostic teaching method of the embodiment of the present application, a third embodiment of the diagnostic teaching method of the embodiment of the present application is proposed.

[0082] The difference between the third embodiment of the diagnosis teaching method and the first and second embodiments of the diagnosis teaching method is that this embodiment is a refinement of the diagnosis teaching method applied to the learning end device steps A2 and A3. Figure 4 , the method comprising:

[0083] Step B2, receiving the vehicle model information of the learning request and determining the target diagnosis teaching content of the ECU to be learned by the server.

[0084] In some specific embodiments, after determining the corresponding learning authority, the server determines the corresponding target diagnostic teaching content according to the vehicle model and ECU in the learning request, and sends the specific diagnostic teaching content to the learning end device, which receives the diagnostic teaching content. Specifically, when the device identifier contained in the learning request is learning end device 1 and the vehicle model is a BMW model, the target diagnostic teaching content corresponding to the learning request is the diagnostic process, fault information, fault repair and other teaching content of the BMW model engine system ECU and body control system ECU. The learning end device receives the target diagnostic teaching content including the diagnostic process, fault information, fault repair and other teaching content of the BMW model engine system ECU and body control system ECU.

[0085] Step B3, based on the target ECU selected by the user from the ECUs to be learned, obtain the simulation file of the target ECU in the server, and learn the diagnostic process of the target ECU.

[0086] In some specific embodiments, when the ECUs to be learned include at least 2, the learning user can select a target ECU from the ECUs to be learned for learning. After the user determines the target ECU, it is sent to the server through the learning end device. The server determines the diagnostic simulation file matching the target ECU in the preset diagnostic teaching database according to the target ECU, and sends the diagnostic simulation file to the learning end device. The user uses the learning end device to complete the diagnostic learning process according to the acquired diagnostic simulation file. Among them, the preset diagnostic teaching database is formed by the diagnostic simulation file generated by the teaching end device according to the teacher's operation. Continuing the above example, when the learning end device 1 initiates a learning request, the target diagnostic teaching content it obtains includes the diagnostic process, fault information, fault repair and other teaching contents of the BMW model engine system ECU and the body control system ECU. Then the user selects the engine system ECU as the target ECU, and then the server finds the diagnostic simulation file of the engine system ECU in the preset diagnostic teaching content database according to the engine system ECU, and sends it to the learning end device 1. After receiving the diagnostic simulation file of the engine system ECU, the learning end device 1 can learn the diagnostic process of the engine system ECU.

[0087] Reference Figure 5 , step B3 specifically includes:

[0088] Step b1, obtaining the target simulated fault code determined by the server according to the target ECU.

[0089] In the process of vehicle fault diagnosis, we usually analyze the cause of the vehicle fault by reading the fault code determined by the ECU, and after knowing the cause of the vehicle fault, we use it to eliminate the vehicle fault. Furthermore, in the process of vehicle diagnosis teaching, the fault code still plays a very important role. We can analyze and diagnose the specific cause of the vehicle fault through the fault code determined by the target ECU, and achieve the purpose of simulated diagnosis teaching of vehicle diagnosis.

[0090] In some specific embodiments, a target ECU is selected from the ECUs to be learned, and the server matches the corresponding simulation file according to the target ECU, and calls the target simulation fault code corresponding to the target ECU in the simulation file. Specifically, a learning request is obtained through a learning end device, and the target diagnostic teaching content in the server that needs to be called under the learning authority is determined according to the learning request. According to the target diagnostic teaching content, the corresponding vehicle model information and the ECU to be learned corresponding to the learning authority are obtained. The user selects the ECU to be learned through the learning end device, obtains the target ECU for diagnostic simulation teaching, obtains the corresponding simulation file in the server according to the target ECU, and determines the corresponding target simulation fault code according to the above target ECU. Among them, the above fault code information includes the vehicle number and the fault content, for example, 9000-B6 / 1 (Camshaft Hall sensor) Nosignal.

[0091] Step b2, displaying the target simulated fault code.

[0092] The target simulation fault code in the simulation file corresponding to the target ECU in the target diagnostic teaching content in the server is returned to the learning end device and displayed in the learning end device to achieve the purpose of diagnostic simulation teaching.

[0093] In this embodiment, after the learning end device sends a learning request to the server, it receives the target diagnostic teaching content returned by the server, which includes the ECU diagnostic teaching content to be learned determined according to the vehicle model information in the learning request, and then the learning end device selects the target ECU from the ECU to be learned according to the user's instructions, obtains the simulation file of the target ECU in the server, simulates the learning diagnosis process according to the simulation file, and then further obtains the target simulation fault code determined by the server according to the target ECU, and displays the target simulation fault code after completing the simulation learning diagnosis process, thereby allowing users to have a more realistic diagnostic experience, improving the authenticity of vehicle diagnosis teaching, and further improving the efficiency of vehicle diagnosis teaching.

[0094] Furthermore, based on the first, second and third embodiments of the diagnostic teaching method of the embodiments of the present application, a fourth embodiment of the diagnostic teaching method of the embodiments of the present application is proposed.

[0095] The fourth embodiment of the diagnostic teaching method is different from the first, second and third embodiments of the diagnostic teaching method in that the fourth embodiment of the diagnostic teaching method further includes a solution for obtaining a maintenance instruction demonstration. Figure 6 , the method further comprises:

[0096] Step C1: Obtain the user's maintenance guidance demonstration request.

[0097] In some specific embodiments, the learning end device is connected to the virtual reality device for communication. After the learning end device performs simulation learning according to the target diagnosis teaching content, it can also demonstrate the maintenance guidance demonstration request based on the target fault code through the virtual reality device. In some specific application scenarios, the learning end device can display the fault repair demonstration option according to the displayed target simulation fault code after the user completes the simulation learning. When the user's selection of the fault repair demonstration option is obtained, the user's maintenance guidance demonstration request is obtained.

[0098] Step C2: Determine demonstration information according to the maintenance guidance demonstration request, and send the demonstration information to the virtual reality device, while prompting the user to wear the virtual reality device, so that the virtual reality device determines the target demonstration content according to the demonstration information and presents it to the user.

[0099] In some specific embodiments, after obtaining the user's maintenance guidance demonstration request, the learning end device determines the demonstration information according to the fault maintenance demonstration option selected by the user, and the demonstration information includes information such as vehicle model, ECU, fault code, etc. The learning end device sends the demonstration information to the virtual reality display device and reminds the user to wear the virtual reality device. After receiving the demonstration information, the virtual reality device determines the target demonstration content according to the demonstration information and presents it to the user. In some specific application scenarios, the virtual reality device can determine the 3D vehicle schematic diagram and the position of the ECU in the 3D vehicle schematic diagram according to the vehicle model and ECU in the demonstration information, and determine the maintenance demonstration program of the fault code according to the fault code in the demonstration information, that is, the operation process of each maintenance step, and then present the 3D vehicle schematic diagram, the position of the ECU in the 3D vehicle schematic diagram, and the operation process of each maintenance step corresponding to the fault code to the user, so that the user can experience the maintenance process more intuitively.

[0100] In the scheme of this embodiment, after the learning end device performs diagnostic simulation learning according to the target diagnostic teaching content, it obtains the user's maintenance guidance demonstration request, determines demonstration information according to the maintenance guidance demonstration request, and sends the demonstration information to the virtual reality device that is communicatively connected to the learning end device, so that the virtual reality device determines the target demonstration content according to the demonstration information and presents it to the user, so that the user can view the maintenance process more intuitively and three-dimensionally through the virtual reality device, providing the user with a vivid and realistic learning environment, and improving the teaching effect of vehicle maintenance.

[0101] Furthermore, based on the first, second, third and fourth embodiments of the diagnostic teaching method of the embodiments of the present application, a fifth embodiment of the diagnostic teaching method of the embodiments of the present application is proposed.

[0102] The fifth embodiment of the diagnosis teaching method is different from the first, second, third and fourth embodiments of the diagnosis teaching method in that, in this embodiment, the diagnosis teaching method is applied to a virtual reality device, referring to Figure 7 , the method further comprises:

[0103] Step D1, obtaining demonstration information sent by the learning terminal device.

[0104] Wherein, the demonstration information is generated by the student terminal device according to the user's maintenance guidance demonstration request, the maintenance guidance demonstration request is obtained by the student terminal device after the user performs diagnostic simulation learning according to the target diagnosis teaching content, the target diagnosis teaching content is obtained by the student terminal device from the server, the target diagnosis teaching content is determined by the server according to the learning request, and the learning request is sent by the student terminal device to the server;

[0105] In some specific embodiments, the learning end device can display a fault repair demonstration option according to the displayed target simulated fault code after the user completes the simulation learning. When the user's selection of the fault repair demonstration option is obtained, the learning end device obtains the user's maintenance guidance demonstration request. At this time, the learning end device can determine the demonstration information such as vehicle type, ECU, fault code information, etc. according to the maintenance guidance demonstration request. After receiving the demonstration information, the virtual reality device connected to the learning end device can determine the demonstration content according to the demonstration information.

[0106] Step D2: determining target demonstration content based on the demonstration information and presenting it to the user.

[0107] The demonstration information includes vehicle model information, target ECU and target simulated fault code. According to the demonstration information, the target demonstration content is determined to include:

[0108] Determine the location information of the target ECU on the vehicle model and / or the maintenance operation process of the target simulated fault code.

[0109] In some specific embodiments, after acquiring the demonstration information of the learning end device, the virtual reality device determines the position information of the target ECU on the vehicle model for the simulated maintenance teaching demonstration in the demonstration information and / or the maintenance operation process of the target simulated fault code based on the demonstration information. For example, when the demonstration information is the engine ECU of a BMW model and the fault code of the engine ECU, the virtual reality device determines that the target demonstration content includes the 3D vehicle schematic diagram of the BMW model, the position of the engine ECU on the 3D vehicle schematic diagram, the operation process of the dynamic maintenance step of the fault code, etc. according to the demonstration information.

[0110] In some optional embodiments, presenting the target demonstration content to the user specifically includes:

If there is a new car model, various fault repair demonstration programs for the new car model can be added. By only upgrading the software, corresponding demonstration programs for more car models or different faults can be obtained, thereby being able to display more car models, vehicle components and repair methods, and expand the corresponding demonstration content.

The learning authority of student A includes the vehicle models that the learning end device can perform simulated diagnostic learning and the electronic control system ECU for simulated diagnosis. Specifically, for example, student A can simulate the engine system ECU diagnosis and transmission system ECU diagnosis of Volkswagen models, the engine system ECU diagnosis and body control system ECU diagnosis of BMW models.

[0120] After completing the simulation diagnosis teaching, if student A of the student-side device still wants to obtain the maintenance method of the simulated fault of the target ECU Volkswagen vehicle transmission system ECU of the above target diagnosis teaching content, student A can select the maintenance guidance demonstration option corresponding to the simulated fault code through the fault code interface of the learning-side device, and automatically generate a maintenance guidance demonstration request through the maintenance guidance demonstration option. The learning-side device determines the demonstration information corresponding to the maintenance guidance demonstration request of student A according to the maintenance guidance demonstration request, and the demonstration information includes the transmission system ECU of the Volkswagen vehicle and the fault code information of the transmission system ECU. Then, the learning-side device sends the demonstration information to the virtual reality device connected to the learning-side device for communication, and prompts student A to wear the virtual reality device at the same time. The virtual reality device determines the target demonstration content including the 3D vehicle schematic diagram of the Volkswagen vehicle, the position of the transmission system ECU on the 3D vehicle schematic diagram, and / or the maintenance operation process corresponding to the target simulated fault code according to the demonstration information, and presents it to the student A. During the demonstration, the virtual reality device dynamically adjusts the demonstration content according to the interactive instructions of the student A, such as adjusting the viewing angle, switching different component models, adjusting the progress of the maintenance steps, etc., thereby completing the maintenance simulation teaching.
